Stricter grammar: multiline `config` blocks only; no one-line braced workflows; no semicolon-separated statements in workflow/rule bodies. -- **Runtime:** Single-line shell steps run in the Node runtime (`sh -c`); script capture only on success; async `run` + `recover` return propagation fixed; mock prompts use JSON arm dispatch and an in-memory response queue; inbox artifact files are written only when a route consumes the channel. -- **CLI / install:** Failure footers use the **last** failed step in `run_summary.jsonl`; curl install ships `package.json` so stable installs resolve the correct default Docker image tag. -- **Language:** RHS bare identifiers and bare dotted identifiers are treated as interpolation sugar where applicable. -- **Library:** `artifacts.save(paths)` in single-argument form (path or newline-separated list); `git format-patch` workflows use `--stdout` so patch bytes are captured. -- **Repo:** `node-workflow-runtime` split into arg-parser, event-emitter, and mock modules; test directories consolidated under `integration/`, `test-fixtures/`, `test-infra/`; `JAIPH_TEST_MODE` no longer suppresses stderr events in runtime code (constructor option instead). -- **Docs / DX:** Agent-proxy design note; explicit parse error for `test` blocks outside `*.test.jh`; architecture/inbox corrections; getting-started shortened. +- Feature: `for in { ... }` loop. +- Simplifying: Sequential inbox only; stricter grammar (multiline `config`, no one-line braced workflows, no `;` in workflow/rule bodies). +- Hardening, test refactoring and bug fixes ## All changes +- **Language:** `for in { … }` in workflows and rules iterates newline-delimited lines of a string binding. Newlines normalize `\r\n` to `\n`; a single trailing empty segment from a final newline is omitted. Lines are not trimmed and empty interior lines are still iterated unless the body skips them (e.g. `if line != "" { … }`). Documented in `docs/language.md`. +- **Tests / QA:** Unit tests for string line splitting (`src/runtime/string-lines.test.ts`); E2E `e2e/tests/135_for_string_lines.sh`. - **Breaking — Language:** Inline one-line `config { k = v }` is removed — only the multiline `config {\n … \n}` form parses (matches documented grammar). The formatter no longer emits compact inline `config`, which would be invalid input. Examples such as `examples/async.jh` were migrated. - **Breaking — Language:** Single-line `workflow name() { stmt }` braced form removed; workflow and rule bodies require one statement per line as in the grammar. - **Breaking — Language:** Semicolons no longer separate statements in workflow/rule bodies (`splitStatementsOnSemicolons` remains for `match` arms). Multiple statements on one line joined by `;` must be split across lines.

Docs updated in `docs/architecture.md` and `docs/cli.md`. - **Performance — `jaiph install` parallelism:** Missing-library clones now run in parallel through a small bounded-concurrency executor (default 4 in flight), replacing the previous sequential `execSync` loop. The user contract is unchanged: warm-path libraries (target directory exists and `--force` is absent) still skip without invoking `git` for both explicit args and restore-from-lock; failed clones still exit non-zero and do not produce a lock entry; restore-from-lock still does not invent new lock entries. The default clone runner now uses `spawn("git", ["clone", "--depth", "1", …])` so multiple clones can overlap network and process latency. `runInstall` is now `async` and exposes injectable `CloneRunner` / `concurrency` options for testing. Tests cover concurrent overlap (peak in-flight ≥ 2), warm-path skipping for explicit args and restore, invalid-remote and unknown-ref failure paths, mixed success/failure lockfile bookkeeping, and the existing corrupt/missing-lockfile behavior.

For local (non-Docker) runs the CLI serializes the prep to `/.jaiph-compile-prep.json` with `writeCompilePrep` and points the child at it through the internal env var **`JAIPH_COMPILE_PREP_FILE`**. The runner deserializes the file and passes the cached `CompilePrep` to `buildRuntimeGraph(sourceFile, workspaceRoot, prep)`, which builds the `RuntimeGraph` from the cached `Map` instead of re-reading `.jh` sources. When the env var is absent — Docker `jaiph run`, `jaiph run --raw`, or any other caller — the runner falls back to the on-disk parse path (`buildRuntimeGraph` reads each module via `parsejaiph`). Either path runs `NodeWorkflowRuntime` with the same `RuntimeGraph` shape — `buildRuntimeGraph` still does **not** run `validateReferences`. Prompt steps, script subprocesses, inbox dispatch, and event emission are handled in the runtime kernel — workflows and rules are interpreted in-process; only `script` steps spawn a managed shell.

Variables marked ** - `JAIPH_META_FILE` — path to the run metadata file (under the CLI’s build output directory for that invocation). Set on the **detached workflow child** only; the parent strips any inherited value so leftover exports do not collide. The runner writes `run_dir=` / `summary_file=` lines for the host to read after exit. - `JAIPH_SOURCE_ABS` — absolute path to the entry `.jh` file; set by the CLI for **`jaiph run`** before spawn. Required by the runner (local and Docker). - `JAIPH_SCRIPTS` — directory containing emitted **`script`** files for this run; set after **`buildScripts()`**. Any **`JAIPH_SCRIPTS`** exported in the parent shell is cleared before launch so nested toolchains do not point at the wrong tree. +- `JAIPH_COMPILE_PREP_FILE` — absolute path to a `CompilePrep` JSON snapshot (`/.jaiph-compile-prep.json`) the CLI wrote with `writeCompilePrep`. Set by the CLI **only** for the default local (non-Docker, non-`--raw`) `jaiph run` path so the spawned `node-workflow-runner.js` builds the runtime graph from the cached ASTs instead of re-reading the import closure. The file is internal and may move; do not depend on its path or contents. When the variable is absent (Docker `jaiph run`, `jaiph run --raw`, `jaiph test`), `buildRuntimeGraph()` falls back to parsing `.jh` from disk. See [Architecture — Local single-parse compile prep](architecture.md#local-single-parse-compile-prep). - `JAIPH_RUN_DIR`, `JAIPH_RUN_ID`, `JAIPH_RUN_SUMMARY_FILE` — for a normal (**non-raw**) **`jaiph run`**, the host generates **`JAIPH_RUN_ID`** once per invocation (UUID), passes it through to the detached child (and into Docker when sandboxed), and Docker failure-path discovery can match summaries by this id. The runtime uses **`JAIPH_RUN_ID`** as the stable run identifier; if it is absent, the runtime may assign its own UUID. **`JAIPH_RUN_DIR`** and **`JAIPH_RUN_SUMMARY_FILE`** are set inside the runner once the UTC run directory exists. - `JAIPH_SOURCE_FILE` — set automatically by the CLI to the entry file **basename**.

Composition happens in orchestration. | -| 12 | Shared utility code lives in **shared bash libraries** (sourced explicitly in bash scripts), not in Jaiph script cross-calls. | -| 13 | `if` uses **brace syntax** (`if ... { } else { }`), **`not`** for negation, **`else if`** for chaining. No `then`/`fi`/`elif`. | -| 14 | Scripts transpile to **separate executable files** with `+x` permission. | -| 15 | Default shebang is `#!/usr/bin/env bash`. User can provide a custom shebang as the first line of the script body (e.g. `#!/usr/bin/env node`). | -| 16 | Workflows, rules, and scripts support **named parameters** in declarations. Positional `$1`/`$2` boilerplate is eliminated. | - -## Legality Matrix - -### `workflow` - -| Construct | Allowed | Syntax | -|-----------|---------|--------| -| config | Yes | `config { key = "value" }` | -| const | Yes | `const name = "value"` / `const name = run ref` / `const name = ensure ref` / `const name = prompt "text"` | -| run | Yes | `run ref [args]` / `run ref [args] &` (async) | -| ensure | Yes | `ensure ref [args]` / `ensure ref [args] recover { ... }` | -| prompt | Yes | `prompt "text"` / `const name = prompt "text"` / `const name = prompt "text" returns '{ ... }'` | -| log | Yes | `log "message"` | -| logerr | Yes | `logerr "message"` | -| return | Yes | `return "value"` / `return $var` | -| fail | Yes | `fail "reason"` | -| if | Yes | `if [not] ensure ref { ... } [else if ...] [else { ... }]` / `if [not] run ref { ... }` | -| route | Yes | `channel -> ref1, ref2` | -| send | Yes | `channel <- "value"` / `channel <- $var` / `channel <- run ref` | -| wait | Yes | `wait` (waits for async `run` steps) | -| Raw shell | **No** | Hard parser error with rewrite guidance | - -### `rule` - -| Construct | Allowed | Syntax | -|-----------|---------|--------| -| const | Yes | `const name = "value"` / `const name = run ref` / `const name = ensure ref` (no `prompt` capture) | -| ensure | Yes | `ensure ref [args]` — other rules only, **no `recover`** | -| run | Yes | `run ref [args]` — **scripts only**, not workflows | -| log | Yes | `log "message"` | -| logerr | Yes | `logerr "message"` | -| return | Yes | `return "value"` / `return $var` | -| fail | Yes | `fail "reason"` | -| if | Yes | `if [not] ensure ref { ... }` / `if [not] run ref { ... }` (run targets scripts only) | -| prompt | **No** | Rules don't interact with AI | -| route / send | **No** | Rules don't use channels | -| async (`&`, `wait`) | **No** | | -| recover (in `ensure`) | **No** | Not in rule-to-rule calls | -| Raw shell | **No** | Hard parser error | - -### `script` - -| Construct | Allowed | Syntax | -|-----------|---------|--------| -| Custom shebang | Yes | `#!/usr/bin/env node` (first line of body; omit for default `#!/usr/bin/env bash`) | -| All body content | Yes | Full language content matching the shebang (bash by default) | -| Nested bash functions | Yes (bash) | `helper() { ... }` (internal to the script body) | -| Shared bash via workspace lib dir | **No** | Use `import script`, a sibling module, or inline bash in a `script` block — `JAIPH_LIB` is not provided | -| `return N` / `exit N` | Yes (bash) | Exit code (integer only) | -| stdout (`echo`, `printf`) | Yes | Value output mechanism | -| `local` | Yes (bash) | Bash variable declarations | -| Other Jaiph script calls | **No** | Scripts are atomic; compose in orchestration | -| `run`, `ensure`, `prompt` | **No** | Hard parser error (bash scripts only; skipped for custom shebangs) | -| `return "value"` | **No** | Use `echo` for values, `return 0` for success (bash scripts only) | -| `fail`, `const`, `log`, `logerr` | **No** | Jaiph keywords, not available in scripts (bash scripts only; skipped for custom shebangs) | -| Parent scope variables | **No** | Full isolation — only positional args | - -**Jaiph keyword guard**: for bash scripts (no shebang or `#!/usr/bin/env bash`), the parser rejects Jaiph-level keywords (`run`, `ensure`, `fail`, `const`, `log`, `logerr`, `prompt`) in the body. For custom shebangs (e.g. `#!/usr/bin/env node`), the guard is skipped — the user owns the body entirely. - -## Named Parameters - -All constructs support named parameters in their declarations: - -``` -workflow implement(task, role_name) { ... } -rule ensure_is_number(value) { ... } -script check_hash(file_path, expected_hash) { ... } -``` - -**Semantics:** - -- Parameters are available as named local variables inside the construct body. -- For workflows/rules: the transpiler emits `local task="$1"; local role_name="$2"` at the top of the function body. -- For bash scripts: the transpiler prepends `local file_path="$1"; local expected_hash="$2"` to the script file. For non-bash shebangs, named params are documentary only (the language uses its own argv mechanism). -- **Optional/default parameters**: `workflow deploy(env, version, dry_run = "false")` transpiles to `local dry_run="${3:-false}"`. -- Both positional and named calling conventions are valid at call sites: - - `run implement "$task" "$role_name"` — positional, mapped by declaration order. - - `run implement task="$task" role_name="$role_name"` — named (already partially supported via `parseParamKeysFromArgs`). -- **Arity validation**: the validator can check call sites against the declaration. `run implement` with zero args when `implement` declares two required params is a validation error. -- **Parentheses are optional**: `workflow default() { ... }` (no params) remains valid. Constructs with params use `name(params) { ... }`. - -## Script Isolation and Transpilation Model - -Scripts execute in **full isolation**. They receive only their positional arguments. No inherited variables from the orchestration scope, module-level constants, or other scripts' state. - -### Transpilation to separate files - -Each `script` block transpiles to a **standalone executable file** in the build output: - -``` -build/ - scripts/ - check_is_number # #!/usr/bin/env bash, +x - check_json_schema # #!/usr/bin/env node, +x - select_role # #!/usr/bin/env bash, +x - module_name.sh # orchestration (workflows + rules) -``` - -The transpiler: -1. Extracts each `script` body verbatim -2. Prepends the shebang (user-provided or default `#!/usr/bin/env bash`) -3. Writes to `build/scripts/` with `chmod +x` -4. In the module `.sh`, script calls become: `"$JAIPH_SCRIPTS/" "$@"` - -The runtime sets `$JAIPH_SCRIPTS` to the build output scripts directory. - -### Shebang syntax - -The first non-empty line of the script body is checked for `#!`. If present, it becomes the file's shebang. If absent, `#!/usr/bin/env bash` is used. - -``` -script check_json() { - #!/usr/bin/env node - const data = JSON.parse(process.argv[2]); - process.exit(data.valid ? 0 : 1); -} - -script check_is_number() { - [[ "$1" =~ ^[0-9]+$ ]] -} -``` - -### Data flow - -**Data flow is always explicit**: -- **Input**: named parameters (declared in signature) or positional arguments (`$1`, `$2`, ...). Named params are syntactic sugar — they transpile to positional arg assignments. -- **Output**: stdout (value), stderr (diagnostics), exit code (success/failure) -- **No side channel**: scripts cannot read `const` variables from workflows/rules - -### Shared utility code (bash scripts only) - -Scripts cannot call other Jaiph scripts. Factor repeated bash into **`import script "./helper.sh" as helper`** (path relative to the `.jh` file), another `.jh` module, or a small extra `script` in the same module. Do not use a workspace-wide bash drop directory outside the compiler model. - -Non-bash scripts use their language's own module system for shared code. - -## Semantics: Values, Returns, Failures - -### Scripts (isolated, standalone executables) - -Values are passed via **stdout**. Caller captures with `const result = run script_name`. - -Exit code determines success/failure: `return 0` / `exit 0` = success, `return 1` / `exit 1` = failure. - -The existing `jaiph::set_return_value` mechanism is **removed** from script transpilation. `return "$string"` in a bash script body is a **parser error** (bash `return` only accepts integers). - -### Workflows - -`return "value"` passes a value to the caller via the Jaiph runtime (not stdout). - -`fail "reason"` terminates the workflow with a non-zero exit and logs the reason to stderr. An unrecovered `ensure` failure also terminates the workflow. - -Exit code: 0 on natural completion or `return`. Non-zero on `fail` or unrecovered failure. - -### Rules - -`return "value"` passes a value to the caller. Captured by `const result = ensure rule_name`. - -`fail "reason"` causes the rule to fail. In the caller, this triggers a `recover` block (if present) or aborts. - -A rule that completes without hitting `fail` passes. - -### `fail` vs script failure - -| Context | How to fail | How to return a value | -|---------|-------------|----------------------| -| `script` | `return 1` / `exit 1` | `echo "value"` (stdout) | -| `workflow` | `fail "reason"` | `return "value"` | -| `rule` | `fail "reason"` | `return "value"` | - -## Migration Examples - -### Rule: raw shell → structured - -Before: - -``` -rule ensure_is_number() { - if !

Orchestration only passes the role name and receives the resolved text. Full isolation — script has zero knowledge of caller scope. - -### Send operator - -Before: - -``` -workflow scanner() { - findings <- echo "Found 3 issues in auth module" -} -``` - -After: - -``` -workflow scanner() { - findings <- "Found 3 issues in auth module" -} -``` - -### Rule with value return - -Before: - -``` -rule echo_line() { - echo "this goes to logs only" - return "captured-value" -} -``` - -After: - -``` -script echo_impl() { - echo "this goes to logs only" >&2 -} - -rule echo_line() { - run echo_impl - return "captured-value" -} -``` - -## Pattern Catalog: .jaiph/ and e2e/ audit - -Every `.jh` file was scanned. Below are all patterns found that require migration, grouped by category. - -### P1: Raw shell in workflows (every .jaiph/ file) - -**Files**: queue.jh, docs_parity.jh, simplifier.jh, architect_review.jh, ensure_ci_passes.jh, qa.jh, git.jh, log_keyword.jh, nested_run.jh, workflow_greeting.jh, prompt_unmatched.jh, rule_pass.jh, assign_capture.jh - -**Examples**: `echo "..."`, `printf`, `mkdir -p`, `rm -f`, `exit 0`, `exit 1`, `test -n`, bare assignment (`dataset="testdata"`) - -**Migration**: each becomes a named `script` or a `const` declaration. `exit 0` → `return` (early success). `exit 1` → `fail "reason"`. - -### P2: Raw shell in rules (every rule) - -**Files**: git.jh (`git rev-parse`, `test -z "$(git status)"`), queue.jh (`echo | grep -q`), ensure_ci_passes.jh (`npm run test:ci`), docs_parity.jh (`test -f`, `while IFS= read`), simplifier.jh, say_hello.jh, say_hello_json.jh, current_branch.jh - -**Migration**: shell logic moves to scripts. Rules become structured: `run` the script, `if`/`fail` on the result. - -### P3: Iteration in workflows - -**Files**: architect_review.jh (`while IFS= read -r header; do ... done <<< "$headers"`), docs_parity.jh (`for f in docs/*.md`, `for f in "${docs_md_files[@]}"`). - -**Problem**: the loop body contains orchestration keywords (`run`, `ensure`, `prompt`, `log`). Cannot be pushed to a script. - -**Resolution**: use **workflow recursion**. Extract per-item logic into a workflow, then recurse over the list. Split newline-delimited lists with tiny `script` steps (e.g. `printf '%s\n' "$1" | head -n 1` / `tail -n +2`) or `import script`. - -``` -script list_docs_files() { - for f in docs/*.md; do - echo "$f" - done -} - -workflow process_docs_recursive(file, remaining) { - run docs_page "$file" - - if run has_value "$remaining" { - const next = run first_line "$remaining" - const rest = run rest_lines "$remaining" - run process_docs_recursive "$next" "$rest" - } -} - -workflow default() { - const docs_files = run list_docs_files - const first = run first_line "$docs_files" - const rest = run rest_lines "$docs_files" - run process_docs_recursive "$first" "$rest" -} -``` - -**Future feature: `each` modifier.** Planned syntax sugar that replaces the recursion boilerplate: - -``` -run docs_page each $docs_files -``` - -`each` is a modifier on `run`/`ensure` that calls the target once per newline-delimited item. No loop body, no mutable state, no break/continue. Backward-compatible addition — does not block v1. - -### P4: Bash arrays in workflows - -**File**: docs_parity.jh — builds arrays dynamically (`local files=()`, `files+=("$f")`), passes them as args (`"${files[@]}"`). - -**Resolution**: avoid arrays in orchestration. Represent lists as newline-delimited strings. Scripts that need to process multiple items receive them as a single string argument. Glob expansion (`docs/*.md`) stays in scripts. - -### P5: Mutable variables in workflows - -**File**: architect_review.jh — `local failed=0` then `failed=1` inside a loop to track whether any task failed. - -**Resolution**: restructure to avoid mutable state. The per-item workflow performs side effects (marking tasks). After recursion completes, re-check the final state: - -``` -workflow review_single_task(header) { - const task = run queue.get_task_by_header "$header" - - if run is_dev_ready "$task" { - log "Already dev-ready: $header" - return - } - - const verdict = run review_task "$task" - if run matches "$verdict" "dev-ready" { - run queue.mark_task_dev_ready "$header" - log "Marked dev-ready: $header" - } else { - log "Needs work: $header" - } -} - -workflow default() { - const headers = run queue.get_all_task_headers - # recurse over headers (or use `each` when available) - ... - - const remaining = run queue.count_not_ready - if not run is_zero "$remaining" { - fail "One or more tasks need work" - } -} -``` - -No mutable counter.

Bash string operations (`${var%%pattern}`, `${var//old/new}`) are computation — push to a script. - -| Allowed in `const` RHS | Not allowed (use script) | -|------------------------|---------------------------| -| `"$var"` | `"${var%%pattern}"` | -| `"${var:-default}"` | `"${var//old/new}"` | -| `"${var:+alt}"` | `"${#var}"` | -| `"literal"` | `$(command)` | - -### P11: Script-to-script calls - -**File**: docs_parity.jh — rule `only_expected_docs_changed_after_prompt` calls script `is_allowed_file` directly. - -**Migration**: under full isolation + no script-to-script calls, inline the logic or add a dedicated `import script` helper: - -``` -script check_only_expected_changed(allowed, changed) { - while IFS= read -r f; do - [ -z "$f" ] && continue - if [[ $'\n'"$allowed"$'\n' != *$'\n'"$f"$'\n'* ]]; then - echo "Unexpected file changed: $f" >&2 - return 1 - fi - done <<< "$changed" -} -``` - -## Implementation Plan - -### Phase 0: Architectural prep (before breaking changes) - -**0a. Refactor `validate.ts` — collapse duplicate ref resolution** -- Merge `validateRuleRef`, `validateWorkflowRef`, `validateRunInRuleRef`, `validateRunTargetRef`, `validateBareSendSymbol` into one generic `validateRef(ref, allowedKinds, context)` function -- Target: 788 → ~400 lines -- Zero behavior change - -**0b. Split `emit-workflow.ts` — separate emitters** -- Extract script emission into `emit-script.ts` -- Extract rule emission into `emit-rule.ts` -- `emit-workflow.ts` becomes orchestration-only assembly -- Creates natural seam for Phase 3 (separate script files) - -### Phase 1: Language additions (no breaking changes) - -**1a. Add `fail` keyword** -- AST: new `WorkflowStepDef` variant `{ type: "fail"; message: string; loc: SourceLoc }` -- Parser: recognize `fail "reason"` in `workflows.ts` -- Transpiler: emit `echo "reason" >&2; exit 1` - -**1b. Add `const` declaration** -- AST: new step type `{ type: "const"; name: string; value: ConstValue; loc: SourceLoc }` where `ConstValue` is string-expr | run-capture | ensure-capture | prompt-capture -- Parser: `const name = ...` with RHS dispatch -- Transpiler: emit `local name; name="value"` or appropriate capture form - -**1c. Formalize `wait` as keyword** -- AST: new variant `{ type: "wait"; loc: SourceLoc }` -- Parser: recognize `wait` in workflows (currently falls through to shell) -- Transpiler: emit `wait` - -**1d. Switch `if` to brace syntax** -- Parser: recognize `if [not] ensure/run ref { ... } [else if ...] [else { ... }]` -- Keep old `if ... then ... fi` working during Phase 1 (dual parsing) -- Transpiler: both forms emit the same bash - -### Phase 2: Rule parser rewrite - -**2a. Restructure `RuleDef`** -- Change `RuleDef.commands: string[]` → `RuleDef.steps: RuleStepDef[]` (or reuse `WorkflowStepDef` subset) -- Rewrite `rules.ts` with keyword-aware parsing (mirror `workflows.ts` structure) -- Port existing rule tests first, then validate structured output - -**2b. Update rule emission** -- `emit-workflow.ts`: handle structured rule steps instead of opaque command strings - -### Phase 3: `function` → `script` rename and separate file transpilation - -**3a. Rename keyword** -- Parser: accept `script` keyword instead of `function` -- AST: rename `FunctionDef` → `ScriptDef`, add `shebang?: string` field -- `jaiphModule`: rename `functions` → `scripts` -- Update all validator references - -**3b. Add shebang extraction** -- Parser: check first non-empty line of script body for `#!` -- If present, store in `ScriptDef.shebang` and exclude from body commands -- If absent, `shebang` remains `undefined` (default `#!/usr/bin/env bash`) - -**3c. Conditional keyword guard** -- For bash scripts (no shebang or bash shebang): keep existing Jaiph keyword rejection -- For custom shebangs: skip keyword guard entirely - -**3d. Emit scripts as separate files** -- Change `emitWorkflow` return type: `{ module: string; scripts: ScriptFile[] }` where `ScriptFile = { name: string; content: string; shebang: string }` -- Module `.sh` calls scripts via `"$JAIPH_SCRIPTS/" "$@"` -- `build.ts`: write script files with `chmod +x`, set `$JAIPH_SCRIPTS` - -**3e. Update all first-party `.jh` files** -- Rename `function` → `script` in all `.jaiph/*.jh` files -- Rename in all `e2e/*.jh` fixtures -- Update test fixtures and golden outputs - -**3f. Named parameters** -- Parser: recognize `name(param1, param2)` and `name(param1, param2 = "default")` in workflow, rule, and script declarations -- AST: add `params?: Array<{ name: string; default?: string }>` to `WorkflowDef`, `RuleDef`, `ScriptDef` -- Transpiler: for workflows/rules, emit `local param1="$1"; local param2="$2"` (or `"${2:-default}"` for defaults) at the top of the function body. For bash scripts, prepend the same to the script file. For non-bash scripts, params are documentary only. -- Validator: check call-site arity against declared params. Missing required args = validation error. Extra args beyond declared params = validation warning. -- Update all first-party `.jh` files to use named params where applicable -- Parentheses optional when no params: `workflow default() { ... }` remains valid - -### Phase 4: Script isolation - -**4a. Implement full isolation for script execution** -- Scripts run as separate processes (inherent from separate files + exec) -- Only positional args available (inherent from separate executable) -- Set `$JAIPH_SCRIPTS` and `$JAIPH_WORKSPACE` for script steps (no workspace bash lib dir) - -**4b. Reject script-to-script calls** -- Parser/validator: detect when a script body references another Jaiph script name -- Error: `"scripts cannot call other Jaiph scripts; use import script, inline bash, or compose in a workflow"` - -### Phase 5: Remove shell (breaking changes) - -**5a. Remove shell fallback from workflow parser** -- `workflows.ts`: delete the catch-all `type: "shell"` codepath -- Remove `shellAccumulator` / `braceDepthDelta` shell accumulation -- Emit parser error: `"raw shell is not allowed in workflow; extract to a script"` - -**5b. Remove shell fallback from rule parser** -- Same treatment after Phase 2 - -**5c. Remove old `if` syntax** -- Drop `if ... then ... fi` / `elif` parsing -- Only accept brace syntax with `not` / `else if` - -**5d. Enforce pure output in scripts** -- `scripts.ts`: reject `return "value"` (non-integer return) -- Remove `jaiph::set_return_value` from script transpilation - -**5e. Update send operator** -- Accept `"value"` / `$var` / `run ref` as RHS -- Reject raw shell command as RHS - -### Phase 6: Migrate all first-party code - -- Rewrite all `e2e/*.jh` fixtures -- Rewrite all `.jaiph/*.jh` workflows -- Factor repeated bash into `import script` or extra `script` blocks in the same module (P6, P11) -- Update test fixtures and golden transpilation outputs -- Update docs and README examples - -### Phase 7: Ship - -- Hard parser errors on all legacy syntax -- Error messages include rewrite examples -- Full e2e + golden snapshot CI gate -- Zero P0 parser/runtime failures before merge - -## Code Changes Required - -| File | Change | -|------|--------| -| `src/types.ts` | Rename `FunctionDef` → `ScriptDef`, add `shebang?: string`, add `params?: ParamDef[]`.

A test asserting the export surface of `src/types.ts` fails when those symbols reappear. +4. Every existing parser path that produced a `managed:` sidecar now produces an `Expr` node, and a new parser test asserts the AST shape directly for `return run …`, `return ensure …`, `return match … { … }`, `return run \`…\`(…)`, `log run \`…\`(…)`, and `const x = prompt …`. +5. `npm test` passes.

Users fix one error, recompile, fix the next, recompile. The validator also pre-orders some checks defensively because it knows it will only get to surface one error. A diagnostics collector lets the parser and validator append errors and the run report the full set at the end. + +**Scope:** + +- Introduce `class Diagnostics { errors: JaiphDiagnostic[]; add(...); hasFatal(): boolean; report(): never | void }` (or equivalent). +- Parser and validator append diagnostics instead of throwing for non-fatal errors. A "fatal" tier remains for cases where continuing would produce garbage AST (unterminated triple-quote, unterminated brace block). +- At the end of a compile, `Diagnostics.report()` either prints all collected errors sorted by file/line and exits non-zero, or returns cleanly. The CLI surfaces the full set instead of just the first. +- Existing call sites of `fail()` / `jaiphError()` migrate to `diagnostics.add(...)` where the error is recoverable. + +**Acceptance criteria** (each verified by a test): + +1. A fixture containing **N ≥ 3 independent errors** (e.g. an undefined channel, a duplicate import alias, and an unknown ref in a `run` call) reports all N errors in one compile, not just the first.

The existing single-error tests still pass: every `parse-*.test.ts` and `validate-*.test.ts` fixture that asserts a specific `{ message, line, col, code }` still gets exactly that error (now the only one in `Diagnostics`). +3. `fail()` and `jaiphError()` throwing call-sites are reduced to a documented "fatal" subset (count it in the test).

Each step type's validation is written twice with subtle differences, and the 5-check sequence (`validateNoShellRedirection` → `validateNestedManagedCallArgs` → `validateRef` → `validateArity` → `validateBareIdentifierArgs`) is repeated by hand at 6+ sites per side — at least 12 places to keep in sync. + +**Scope:** + +- Replace the two inner walkers with a single AST visitor parameterized by a `Scope` value: + - `Scope` carries `allow: Set`, `refSpec: RefSpec`, and any other rule-vs-workflow differences. + - A `VALIDATORS: Record` table holds one validator per step type, written once. + - `validateCallStep("run" | "ensure")` is a single helper invoked by both `run` and `ensure` validators with different ref-spec / arity-kind arguments. +- The 5-check sequence is encapsulated in one helper (`validateManagedCallShape` or similar) invoked from each call-bearing validator. +- "Is this step allowed in this scope?" becomes a single set-lookup at the top of the visitor, not three throw sites. +- All existing error messages and error codes (`E_VALIDATE`, etc.) are preserved verbatim — both content and source location (line/col) must match what users see today. + +**Acceptance criteria** (each verified by a test): + +1. `src/transpile/validate.ts` is at most 700 lines (down from 1,441).

Every `E_VALIDATE` error message and error location produced today is produced bit-for-bit by the new code. Add a snapshot-style test over every `validate-*.test.ts` fixture asserting `{ message, line, col, code }` matches the pre-refactor output. +4. Adding a new step type requires adding exactly one row to `VALIDATORS` and (if needed) updating the `Scope.allow` sets.

A grep/size test fails if either bound is violated. +2. `parseBlockStatement` is the single entry point for any statement appearing inside a catch or recover body. Add a test that introduces a new statement form (behind a test-only flag) and asserts it is accepted identically at top level and inside `catch (e) { … }` and `recover(e) { … }` without parser changes inside the catch/recover code path. +3. Every existing parse error message and location related to `catch` / `recover` (bindings missing, too many bindings, unterminated block, etc.) is preserved bit-for-bit.

Order matters — `"run async "` before `"run "`, etc. Quote/triple-quote/backtick/fence/brace state is re-implemented from scratch in at least seven independent scanners across `src/parse/`. Adding a new keyword or fixing a string-aware scanner means changes in multiple places. + +**Scope:** + +- Introduce a tokenizer (`src/parse/tokenize.ts` or similar) that owns *all* scanning state: identifiers, keywords, string literals (single + triple-quoted), backtick bodies, fenced code blocks, line comments, braces, parens, the send arrow `<-`, the match arm arrow `=>`, etc. +- Introduce a recursive-descent parser that consumes the token stream and dispatches via a `STATEMENT: Record` table. +- All ad-hoc scanners in `src/parse/` are deleted: `splitCatchStatements` (if still present), `splitStatementsOnSemicolons`, `matchSendOperator`, `hasUnquotedSendArrow`, `indexOfClosingDoubleQuote`, `stripQuotedArgContent`, `parseSendRhs`'s internal scanner, and any `inDoubleQuote` / `inTripleQuote` / `braceDepth` state machines outside the tokenizer. +- Surface syntax is unchanged. Error messages and error locations are preserved bit-for-bit where the existing tests assert them, and at minimum match in `code` + `line` + `col` everywhere else. +- Staging: it is acceptable (and recommended) to land the new parser behind a flag, run both parsers on the golden corpus in CI, diff their ASTs, and remove the old parser only once the diff is empty. + +**Acceptance criteria** (each verified by a test): + +1. `src/parse/` is at most 4,000 lines total (down from ~8,150), excluding test files. A CI check fails if exceeded. +2. The substrings `inDoubleQuote`, `inTripleQuote`, `braceDepth` appear only inside the tokenizer module. A grep test fails if any of those state-tracking idioms appear in other files under `src/parse/` or `src/transpile/`. +3. `parseBlockStatement` (or whatever the equivalent dispatcher is in the new parser) dispatches via a table, not a cascade. The size of any single function in `src/parse/` is bounded — no function exceeds 120 lines. A test computing function lengths fails if exceeded. +4. Every existing parse-error location and message asserted by `src/parse/parse-*.test.ts` matches verbatim. Add a snapshot test that re-emits `{ code, message, line, col }` for every error fixture and fails on any diff. +5.

The golden test corpus pins behavior. +- **Runtime.** The bash emitter and `runtime/` stay put. + +--- + +## Appendix — Secondary improvements (A–E) + +The five refactors above are the load-bearing changes. The five below are smaller in scope but each addresses a real structural issue that the top 5 do not fully solve on their own. Where a secondary item is coupled to a top-5 refactor, the ordering rationale below makes the dependency explicit. + +### A — Split source-fidelity data from the semantic AST (CST / trivia layer) + +**Touches:** `src/types.ts`, plus every parser/formatter/validator/emitter consumer. + +`WorkflowStepDef` and `jaiphModule` today carry roughly ten fields that exist *only* so the formatter can round-trip: `leadingComments`, `configLeadingComments`, `trailingTopLevelComments`, `configBodySequence`, `topLevelOrder`, `bareSource`, the `tripleQuoted` flags on `literal`/`return`/`log`/`fail`/`send`/`const`, `bodyKind`, `bodyIdentifier`. Every consumer that does *not* care about formatting (validator, emitter) has to either ignore them or thread them through unchanged. + +**Proposed:** introduce a parallel `Trivia` map (keyed by node id) or a separate CST layer that owns the source-fidelity data. The semantic AST stops carrying it; formatter reads from `Trivia` alongside the AST. + +**Why it is appendix-only:** it changes most of the AST consumers, but the change is mechanical once the boundary is drawn. Biggest payoff if scheduled **before** Refactor 3, so the `Expr` shape is decided after the source-fidelity fields have been pulled out and the semantic core is visible. + +### B — Diagnostics collector instead of fail-fast error reporting + +**Touches:** `src/parse/core.ts` (`fail`), `src/errors.ts` (`jaiphError`), every call site in `src/parse/` and `src/transpile/`. + +Today `fail()` and `jaiphError()` both throw on the first error. A user fixes one error, recompiles, fixes the next, recompiles, etc. This is also the reason for some defensive ordering inside the validator — it tries to surface the "most useful" error first because it knows it will only get to surface one. + +**Proposed:** introduce a `Diagnostics` collector. Parser and validator append errors instead of throwing; the compile run reports the full set at the end (sorted by file/line). A "fatal" tier still exists for cases where continuing would produce garbage. + +**Why it is appendix-only:** almost zero marginal cost if done as part of Refactor 4 (visitor-table validator), since the new visitor already needs a unified entry/exit per step. Doing it standalone is also fine but touches more files. + +### C — Single-pass workflow walk + +**Touches:** `src/transpile/validate.ts`. + +The validator walks each workflow's step tree at least three times before its main check loop runs: `collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`. Each walks the same nested step structure (if/for_lines/catch/recover) with subtly different recursion rules. Bug-fixes to "what counts as a binding here" land in 2–3 walkers. + +**Proposed:** one visitor that accumulates `{knownVars, promptSchemas, bindings}` as it descends, and the main per-step validator runs after (or during) that single descent. + +**Why it is appendix-only:** falls out naturally inside Refactor 4. Doing it separately is a fine ~50-line refactor. + +### D — Collapse `bareIdentifierArgs` into a typed `Arg[]` + +**Touches:** `src/types.ts`, `src/parse/core.ts` (`parseCallRef`), validator and emitter. + +Today every call-bearing node carries both `args: string` (raw text) and `bareIdentifierArgs: string[]` (a re-parse of which arguments happened to be bare identifiers). The validator must remember to check `bareIdentifierArgs` exists at each call site. The emitter has to do its own re-parse of `args` because it doesn't trust either field alone. + +**Proposed:** + +```ts +type Arg = + | { kind: "literal"; raw: string } + | { kind: "var"; name: string }; + +// Calls carry args: Arg[]. No second field. No re-parsing downstream. +``` + +**Why it is appendix-only:** can be done inside Refactor 3 (it is part of the same "single AST shape per concept" story) or as a standalone task. Standalone is cleaner if Refactor 3 is otherwise too large. + +### E — Decouple the validator from the runtime + +**Touches:** `src/transpile/validate.ts` (the `import { tripleQuotedRawForRuntime } from "../runtime/orchestration-text"` at the top), `src/runtime/orchestration-text.ts`. + +The validator imports a runtime helper (`tripleQuotedRawForRuntime`) so it can compute "what the runtime will see" when reporting errors. That is a one-way dependency from compile-time on runtime semantics. The right direction is the opposite: the parser/validator decides the canonical string, and the runtime consumes that decision. + +**Proposed:** move the canonicalization into a parser-side helper (e.g. `src/parse/triple-quote.ts:canonicalizeTripleQuotedString`). The runtime imports *that* instead of the validator importing a runtime function. + +**Why it is appendix-only:** small surface (one helper, ~30 lines), but it removes a layering inversion that will keep biting if the runtime grows more such helpers. + +### Ordering with the top 5 + +``` +1. Refactor 5 (ModuleGraph) +2. A (CST/trivia split) ← before Refactor 3 to settle AST shape +3. D (typed Arg[]) ← can fold into Refactor 3 if scoped slightly wider +4. Refactor 3 (Expr collapse) +5. C (single-pass workflow walk) ← prep for validator +6. B (Diagnostics collector) ← prep for validator +7. Refactor 4 (visitor-table validator) +8. E (decouple validator/runtime) +9. Refactor 2 (unify catch/recover) +10. Refactor 1 (tokenizer + RD parser) +``` From 9e7aaeef15bae69fbf6195907d5aac44871d7072 Mon Sep 17 00:00:00 2001 From: Jakub Dzikowski Date: Sat, 16 May 2026 11:13:41 +0200 Subject: [PATCH 05/66] Refactor: promote CompilePrep to ModuleGraph with I/O-pure pipeline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace three divergent module-discovery strategies (validator callbacks, transpiler re-parse paths, and the file-system walk in buildScripts) with a single ModuleGraph representation.

A new `prepareCompile` (`src/transpile/compile-prep.ts`) walks the entry plus its transitive `.jh` imports exactly once and returns a `CompilePrep` record (`{ entryFile, workspaceRoot, astByFile }`). `src/cli/commands/run.ts` reuses the entry AST for `metadataToConfig` (no second parse for the banner), passes the prep into `buildScripts(..., prep)` so `emitScriptsForModule` skips per-file `readFileSync` + `parsejaiph`, and writes a deterministic JSON snapshot to `/.jaiph-compile-prep.json` via `writeCompilePrep`. The spawned runner reads it through the new internal env var `JAIPH_COMPILE_PREP_FILE` and forwards the deserialized prep to `buildRuntimeGraph(entry, workspaceRoot, prep)`, which now consumes the cached `Map` instead of re-walking the import closure on disk. `attachScriptImportStubs` is factored out of `graph.ts` and is idempotent across cached and uncached paths. The env var is set **only** for non-Docker host runs (when `JAIPH_DOCKER_ENABLED` is off); `jaiph run --raw`, `jaiph test`, and Docker launches do not set it and keep their existing parse paths. User-visible run semantics — banner, hooks, run artifacts, `run_summary.jsonl`, return values, exit codes, and `__JAIPH_EVENT__` streaming — are unchanged. New tests in `src/transpile/compile-prep.test.ts` corrupt every source file on disk after `prepareCompile`, then call `buildScripts` + `buildRuntimeGraph` to prove no second parse happens; they also cover cross-module workflow/rule/script resolution, a three-module closure, and the serialize → deserialize → graph round-trip used to cross the parent → child process boundary. Docs updated in `docs/architecture.md` and `docs/cli.md`. +- **Refactor — `ModuleGraph` is the single representation of "all `.jh` modules reachable from an entry point, parsed once":** The previous three traversal strategies for compile-time module discovery (validator re-reading imports through `ValidateContext`, `emitScriptsForModule` re-wrapping the same callbacks with an optional `prep` cache, and `buildScripts` walking the filesystem directly) collapse to one path. `parsejaiph(source, filePath)` is now strictly I/O-pure — it can no longer reach `fs`. The single discovery routine `loadModuleGraph(entry, workspaceRoot?)` (`src/transpile/module-graph.ts`) walks the entry plus its transitive `import` closure and returns `{ entryFile, workspaceRoot?, modules: Map }`; every other compile-time consumer takes the graph and never re-reads `.jh` from disk. `validateReferences(graph)` and `emitScriptsForModuleFromGraph(graph, file, rootDir)` operate entirely in-memory. The `ValidateContext` interface (`resolveImportPath` / `existsSync` / `readFile` / `parse` / `workspaceRoot` callbacks) is deleted from `src/transpile/validate.ts`; the validator consumes the graph and uses `existsSync` only to resolve `import script` paths (non-`.jh` bodies). `CompilePrep` / `prepareCompile` / `writeCompilePrep` / `readCompilePrep` and the optional `prep?` parameter on `emitScriptsForModule` / `buildScripts` are gone; `buildScripts(input, outDir, ws?)` now loads a graph internally and `buildScriptsFromGraph(graph, outDir, rootDir?)` is the entry point for callers that already loaded one. `buildRuntimeGraph` accepts either an entry file path (legacy) or an already-loaded `ModuleGraph` — `RuntimeGraph` is a type alias for `ModuleGraph` (the only "all reachable modules" representation in the codebase). The cross-process cache file moves to `/.jaiph-module-graph.json` (deterministic JSON: entries sorted by absolute path, ASTs included verbatim) via `writeModuleGraph` / `readModuleGraph`, and the internal env var the spawned `node-workflow-runner.js` reads is renamed `JAIPH_MODULE_GRAPH_FILE` (replacing `JAIPH_COMPILE_PREP_FILE`). Scope of the env-var hand-off is unchanged: set only for the default local non-Docker `jaiph run` path; `jaiph run --raw`, `jaiph test`, and Docker launches fall back to `loadModuleGraph` from the source file. User-visible contracts — banner, hooks, run artifacts, `run_summary.jsonl`, `return_value.txt`, exit codes, `__JAIPH_EVENT__` streaming, CLI usage, and the full golden corpus (`compiler-golden.test.ts`, `compiler-edge.acceptance.test.ts`) — are unchanged byte-for-byte. New tests (`src/transpile/module-graph.test.ts`, `src/transpile/pipeline-io-purity.test.ts`) stub `node:fs` to throw on any `.jh` read and run the full pipeline against `test-fixtures/` to pin the I/O-purity invariant; another test instruments `parsejaiph` with a call counter to assert no duplicate parses across `loadModuleGraph` → `validateReferences` → `emit` → `buildRuntimeGraph` for fixtures with transitive imports. `src/transpile/compile-prep.ts` and `compile-prep.test.ts` are removed. Docs updated in `docs/architecture.md`, `docs/cli.md`, and `docs/testing.md`. Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 5. - **Performance — `jaiph install` parallelism:** Missing-library clones now run in parallel through a small bounded-concurrency executor (default 4 in flight), replacing the previous sequential `execSync` loop. The user contract is unchanged: warm-path libraries (target directory exists and `--force` is absent) still skip without invoking `git` for both explicit args and restore-from-lock; failed clones still exit non-zero and do not produce a lock entry; restore-from-lock still does not invent new lock entries. The default clone runner now uses `spawn("git", ["clone", "--depth", "1", …])` so multiple clones can overlap network and process latency. `runInstall` is now `async` and exposes injectable `CloneRunner` / `concurrency` options for testing. Tests cover concurrent overlap (peak in-flight ≥ 2), warm-path skipping for explicit args and restore, invalid-remote and unknown-ref failure paths, mixed success/failure lockfile bookkeeping, and the existing corrupt/missing-lockfile behavior.

The parser exposes parsejaiphWithTrivia → {ast, trivia}; legacy parsejaiph drops trivia for validator / transpiler / runtime / loadModuleGraph. The formatter (emitModule(ast, trivia, opts?)) is Trivia's only consumer. New tests pin the invariants: trivia-ast-shape.test.ts (AC1, type-level), trivia-grep.test.ts (AC2), and roundtrip.test.ts (AC3, parse → format → parse → format bit-for-bit on every fixture under examples/ and test-fixtures/golden-ast/fixtures/).

The parser exposes `parsejaiphWithTrivia(source, filePath) → { ast, trivia }`; the legacy `parsejaiph(source, filePath)` is now a thin wrapper that drops trivia for callers that don't care (validator, transpiler, runtime, `loadModuleGraph`). The formatter (`emitModule(ast, trivia, opts?)`) is the only consumer of `Trivia`; validator, emitter, transpiler, and runtime never import from `src/parse/trivia.ts`. New tests pin the invariants: `src/parse/trivia-ast-shape.test.ts` is a compile-time assertion (with runtime echo) that none of the listed fields reappear on any semantic AST type (AC1); `src/parse/trivia-grep.test.ts` greps validator and emitter source files and fails if any of them references `Trivia` / `createTrivia` / `NodeTrivia` / `ModuleTrivia` or imports from `parse/trivia` (AC2); `src/format/roundtrip.test.ts` walks every `.jh` under `examples/` and `test-fixtures/golden-ast/fixtures/` and asserts `parse → format → parse → format` converges bit-for-bit (AC3). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to drop the moved fields. User-visible contracts (CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming) are unchanged. `npm test` and `npm run build` pass with zero TypeScript strict-mode errors (AC4 / AC5). Out of scope: the `Expr` collapse — this refactor only relocates source-fidelity fields without changing the semantic AST's shape. Docs updated in `docs/architecture.md` (new **Trivia / CST layer** section with anchor `#trivia-cst-layer`, plus updated **Parser**, **AST / Types**, and **Formatter** bullets) and `docs/contributing.md` (new row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix A. - **Refactor — `ModuleGraph` is the single representation of "all `.jh` modules reachable from an entry point, parsed once":** The previous three traversal strategies for compile-time module discovery (validator re-reading imports through `ValidateContext`, `emitScriptsForModule` re-wrapping the same callbacks with an optional `prep` cache, and `buildScripts` walking the filesystem directly) collapse to one path. `parsejaiph(source, filePath)` is now strictly I/O-pure — it can no longer reach `fs`. The single discovery routine `loadModuleGraph(entry, workspaceRoot?)` (`src/transpile/module-graph.ts`) walks the entry plus its transitive `import` closure and returns `{ entryFile, workspaceRoot?, modules: Map }`; every other compile-time consumer takes the graph and never re-reads `.jh` from disk. `validateReferences(graph)` and `emitScriptsForModuleFromGraph(graph, file, rootDir)` operate entirely in-memory. The `ValidateContext` interface (`resolveImportPath` / `existsSync` / `readFile` / `parse` / `workspaceRoot` callbacks) is deleted from `src/transpile/validate.ts`; the validator consumes the graph and uses `existsSync` only to resolve `import script` paths (non-`.jh` bodies). `CompilePrep` / `prepareCompile` / `writeCompilePrep` / `readCompilePrep` and the optional `prep?` parameter on `emitScriptsForModule` / `buildScripts` are gone; `buildScripts(input, outDir, ws?)` now loads a graph internally and `buildScriptsFromGraph(graph, outDir, rootDir?)` is the entry point for callers that already loaded one. `buildRuntimeGraph` accepts either an entry file path (legacy) or an already-loaded `ModuleGraph` — `RuntimeGraph` is a type alias for `ModuleGraph` (the only "all reachable modules" representation in the codebase). The cross-process cache file moves to `/.jaiph-module-graph.json` (deterministic JSON: entries sorted by absolute path, ASTs included verbatim) via `writeModuleGraph` / `readModuleGraph`, and the internal env var the spawned `node-workflow-runner.js` reads is renamed `JAIPH_MODULE_GRAPH_FILE` (replacing `JAIPH_COMPILE_PREP_FILE`). Scope of the env-var hand-off is unchanged: set only for the default local non-Docker `jaiph run` path; `jaiph run --raw`, `jaiph test`, and Docker launches fall back to `loadModuleGraph` from the source file. User-visible contracts — banner, hooks, run artifacts, `run_summary.jsonl`, `return_value.txt`, exit codes, `__JAIPH_EVENT__` streaming, CLI usage, and the full golden corpus (`compiler-golden.test.ts`, `compiler-edge.acceptance.test.ts`) — are unchanged byte-for-byte. New tests (`src/transpile/module-graph.test.ts`, `src/transpile/pipeline-io-purity.test.ts`) stub `node:fs` to throw on any `.jh` read and run the full pipeline against `test-fixtures/` to pin the I/O-purity invariant; another test instruments `parsejaiph` with a call counter to assert no duplicate parses across `loadModuleGraph` → `validateReferences` → `emit` → `buildRuntimeGraph` for fixtures with transitive imports. `src/transpile/compile-prep.ts` and `compile-prep.test.ts` are removed. Docs updated in `docs/architecture.md`, `docs/cli.md`, and `docs/testing.md`. Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 5. - **Performance — `jaiph install` parallelism:** Missing-library clones now run in parallel through a small bounded-concurrency executor (default 4 in flight), replacing the previous sequential `execSync` loop. The user contract is unchanged: warm-path libraries (target directory exists and `--force` is absent) still skip without invoking `git` for both explicit args and restore-from-lock; failed clones still exit non-zero and do not produce a lock entry; restore-from-lock still does not invent new lock entries. The default clone runner now uses `spawn("git", ["clone", "--depth", "1", …])` so multiple clones can overlap network and process latency. `runInstall` is now `async` and exposes injectable `CloneRunner` / `concurrency` options for testing. Tests cover concurrent overlap (peak in-flight ≥ 2), warm-path skipping for explicit args and restore, invalid-remote and unknown-ref failure paths, mixed success/failure lockfile bookkeeping, and the existing corrupt/missing-lockfile behavior.

The parser does the bare-identifier classification once at parse time, and the validator and emitter consume the typed list directly without any downstream re-parse of the raw `args` string. Drops the `validateBareIdentifierArgs` helper; its scope check now lives in the per-step validator that already walks the call. Adds grep and AST-shape regression tests so neither `bareIdentifierArgs` nor an args re-parse can reappear under src/parse or src/transpile.

The validator had to remember to check both fields and call a hand-rolled `validateBareIdentifierArgs` helper at every site; the emitter re-parsed `args` from scratch because it didn't trust either field on its own. Both fields are gone. The parser now classifies each argument once, at parse time, into a new typed sum `type Arg = { kind: "literal"; raw: string } | { kind: "var"; name: string }` and stores it on every call-bearing node as `args?: Arg[]`. Affected nodes: `run` / `ensure` workflow steps, `run_inline_script` steps, the `managed` sidecar on `return` / `log` / `logerr` (in all four shapes — `run`, `ensure`, `run_inline_script`, `match`), the `run_capture` / `ensure_capture` / `run_inline_script_capture` const RHS variants, and the `run` send RHS. Downstream consumers walk the typed list directly: the validator's per-call check sequence is now arity (`args.length`), shell-redirection rejection on `literal` raws, nested-unmanaged-call rejection on `literal` raws, ref resolution, and `var`-arg resolution against in-scope bindings via a new `validateArgVarRefs` (the standalone `validateBareIdentifierArgs` helper is deleted); the formatter renders each `Arg` directly (`var` → bare name, `literal` → raw) instead of re-tokenizing a `${ident}`-rewritten string; the runtime turns `Arg[]` back into the space-separated argv string via `argsToRuntimeString` in `src/parse/core.ts` (`var` → `${name}`, `literal` → raw) so the existing handle-resolution / interpolation path is unchanged. New tests pin the invariants: `src/parse/arg-ast-shape.test.ts` is a compile-time assertion that `bareIdentifierArgs` does not appear on `WorkflowStepDef` (`ensure`, `run`, `run_inline_script`, `log.managed`, `logerr.managed`, `return.managed` in `run` / `ensure` / `run_inline_script` shapes), `ConstRhs` (`run_capture`, `ensure_capture`, `run_inline_script_capture`), or the `run` `SendRhsDef` variant (AC1); `src/parse/arg-grep.test.ts` walks every non-test `.ts` under `src/parse/` and `src/transpile/` and fails if any production file matches `args.split(",")` or the bare token `bareIdentifierArgs` (AC2), and separately fails if any file under `src/transpile/` references `validateBareIdentifierArgs` (AC3). The golden compiler corpus, `validate-*.test.ts` files, and the golden AST corpus pass byte-for-byte (AC4); `npm run build` passes with zero TypeScript strict-mode errors (AC5). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the full `Expr` collapse (next task) and surface syntax. Docs updated in `docs/architecture.md` (extended **AST / Types** bullet documenting the typed `Arg` sum; updated **Validator** and **Formatter** bullets to drop the dual representation), `docs/contributing.md` (new **Call-args AST shape** row in the test-layer table), and `docs/spec-async-handles.md` (replaces the stale `commaArgsToSpaced` reference with `argsToRuntimeString`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix D. - **Refactor — Split source-fidelity data from the semantic AST into a `Trivia` (CST) layer:** Around ten fields whose only consumer was the formatter — `leadingComments` on imports / script imports / channels / `const` decls / `test` blocks, `configLeadingComments`, `trailingTopLevelComments`, `configBodySequence` (both module- and workflow-scoped), `topLevelOrder`, `bareSource` on `return`, the `tripleQuoted` flags on `literal` / `return` / `log` / `logerr` / `fail` / `send` / `const`, and the prompt / script `bodyKind` / `bodyIdentifier` discriminators — are removed from `jaiphModule`, `WorkflowStepDef`, `ConstRhs`, `SendRhsDef`, `WorkflowMetadata`, `ImportDef`, `ScriptImportDef`, `ChannelDef`, `ScriptDef`, and `TestBlockDef`, and re-homed in a new parallel `Trivia` store (`src/parse/trivia.ts`) keyed by AST-node identity (per-node `WeakMap`) plus a small `ModuleTrivia` record for module-level data. The parser exposes `parsejaiphWithTrivia(source, filePath) → { ast, trivia }`; the legacy `parsejaiph(source, filePath)` is now a thin wrapper that drops trivia for callers that don't care (validator, transpiler, runtime, `loadModuleGraph`). The formatter (`emitModule(ast, trivia, opts?)`) is the only consumer of `Trivia`; validator, emitter, transpiler, and runtime never import from `src/parse/trivia.ts`. New tests pin the invariants: `src/parse/trivia-ast-shape.test.ts` is a compile-time assertion (with runtime echo) that none of the listed fields reappear on any semantic AST type (AC1); `src/parse/trivia-grep.test.ts` greps validator and emitter source files and fails if any of them references `Trivia` / `createTrivia` / `NodeTrivia` / `ModuleTrivia` or imports from `parse/trivia` (AC2); `src/format/roundtrip.test.ts` walks every `.jh` under `examples/` and `test-fixtures/golden-ast/fixtures/` and asserts `parse → format → parse → format` converges bit-for-bit (AC3). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to drop the moved fields. User-visible contracts (CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming) are unchanged. `npm test` and `npm run build` pass with zero TypeScript strict-mode errors (AC4 / AC5). Out of scope: the `Expr` collapse — this refactor only relocates source-fidelity fields without changing the semantic AST's shape. Docs updated in `docs/architecture.md` (new **Trivia / CST layer** section with anchor `#trivia-cst-layer`, plus updated **Parser**, **AST / Types**, and **Formatter** bullets) and `docs/contributing.md` (new row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix A. - **Refactor — `ModuleGraph` is the single representation of "all `.jh` modules reachable from an entry point, parsed once":** The previous three traversal strategies for compile-time module discovery (validator re-reading imports through `ValidateContext`, `emitScriptsForModule` re-wrapping the same callbacks with an optional `prep` cache, and `buildScripts` walking the filesystem directly) collapse to one path. `parsejaiph(source, filePath)` is now strictly I/O-pure — it can no longer reach `fs`. The single discovery routine `loadModuleGraph(entry, workspaceRoot?)` (`src/transpile/module-graph.ts`) walks the entry plus its transitive `import` closure and returns `{ entryFile, workspaceRoot?, modules: Map }`; every other compile-time consumer takes the graph and never re-reads `.jh` from disk. `validateReferences(graph)` and `emitScriptsForModuleFromGraph(graph, file, rootDir)` operate entirely in-memory. The `ValidateContext` interface (`resolveImportPath` / `existsSync` / `readFile` / `parse` / `workspaceRoot` callbacks) is deleted from `src/transpile/validate.ts`; the validator consumes the graph and uses `existsSync` only to resolve `import script` paths (non-`.jh` bodies). `CompilePrep` / `prepareCompile` / `writeCompilePrep` / `readCompilePrep` and the optional `prep?` parameter on `emitScriptsForModule` / `buildScripts` are gone; `buildScripts(input, outDir, ws?)` now loads a graph internally and `buildScriptsFromGraph(graph, outDir, rootDir?)` is the entry point for callers that already loaded one. `buildRuntimeGraph` accepts either an entry file path (legacy) or an already-loaded `ModuleGraph` — `RuntimeGraph` is a type alias for `ModuleGraph` (the only "all reachable modules" representation in the codebase). The cross-process cache file moves to `/.jaiph-module-graph.json` (deterministic JSON: entries sorted by absolute path, ASTs included verbatim) via `writeModuleGraph` / `readModuleGraph`, and the internal env var the spawned `node-workflow-runner.js` reads is renamed `JAIPH_MODULE_GRAPH_FILE` (replacing `JAIPH_COMPILE_PREP_FILE`). Scope of the env-var hand-off is unchanged: set only for the default local non-Docker `jaiph run` path; `jaiph run --raw`, `jaiph test`, and Docker launches fall back to `loadModuleGraph` from the source file. User-visible contracts — banner, hooks, run artifacts, `run_summary.jsonl`, `return_value.txt`, exit codes, `__JAIPH_EVENT__` streaming, CLI usage, and the full golden corpus (`compiler-golden.test.ts`, `compiler-edge.acceptance.test.ts`) — are unchanged byte-for-byte. New tests (`src/transpile/module-graph.test.ts`, `src/transpile/pipeline-io-purity.test.ts`) stub `node:fs` to throw on any `.jh` read and run the full pipeline against `test-fixtures/` to pin the I/O-purity invariant; another test instruments `parsejaiph` with a call counter to assert no duplicate parses across `loadModuleGraph` → `validateReferences` → `emit` → `buildRuntimeGraph` for fixtures with transitive imports. `src/transpile/compile-prep.ts` and `compile-prep.test.ts` are removed. Docs updated in `docs/architecture.md`, `docs/cli.md`, and `docs/testing.md`. Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 5. - **Performance — `jaiph install` parallelism:** Missing-library clones now run in parallel through a small bounded-concurrency executor (default 4 in flight), replacing the previous sequential `execSync` loop. The user contract is unchanged: warm-path libraries (target directory exists and `--force` is absent) still skip without invoking `git` for both explicit args and restore-from-lock; failed clones still exit non-zero and do not produce a lock entry; restore-from-lock still does not invent new lock entries. The default clone runner now uses `spawn("git", ["clone", "--depth", "1", …])` so multiple clones can overlap network and process latency. `runInstall` is now `async` and exposes injectable `CloneRunner` / `concurrency` options for testing. Tests cover concurrent overlap (peak in-flight ≥ 2), warm-path skipping for explicit args and restore, invalid-remote and unknown-ref failure paths, mixed success/failure lockfile bookkeeping, and the existing corrupt/missing-lockfile behavior.

Parser, validator, formatter, emitter, runtime, and golden AST fixtures are migrated in lockstep; a new `src/types-shape.test.ts` enforces the acceptance criteria (no placeholder strings, exactly 8 step variants, no exported ConstRhs / SendRhsDef).

Inline scripts added a fourth (`run_inline_script_capture`); `prompt`, `match`, and `ensure` captures repeated the same dual representation. The validator, formatter, emitter, and runtime each had to handle both branches at every site. All three encodings are gone. The semantic AST now has a single `Expr` tagged union — `literal | call | ensure_call | inline_script | prompt | match | shell | bare_ref` — used everywhere a value can appear: `const name = `, `return `, `send channel <- `, the message of `log` / `logerr` / `fail`, and the body of an `exec` step (the new statement-form managed call, where the value is consumed for its side effects plus optional capture). `ConstRhs` and `SendRhsDef` are deleted as separate types. The `managed:` sidecar field is deleted from `WorkflowStepDef`. The placeholder strings `"__match__"`, `"run inline_script"`, and `"__JAIPH_MANAGED__"` no longer appear anywhere under `src/`. `WorkflowStepDef` collapses from 14 variants to **8** (`exec`, `const`, `return`, `send`, `say`, `if`, `for_lines`, `trivia`): `exec` is the new managed-statement form covering the prior `run` / `ensure` / `run_inline_script` / `prompt` / `shell` / standalone `match` cases (the discriminator now lives inside `body.kind`, with `captureName` / `catch` / `recover` as step-level attributes); `say` covers the prior `log` / `logerr` / `fail` cases (`level: "fail"` aborts the workflow with the message, otherwise the message is written to the corresponding stream); `comment` / `blank_line` collapse into a single `trivia` variant (formatter-only, skipped by validator and runtime). The parser builds `Expr` nodes directly: `parseConstRhs` returns `{ value: Expr }`; `parseSendRhs` returns `{ value: Expr }`; `parsePromptStep` returns an `exec` step whose `body` is an `Expr.prompt`; `return run …` / `return ensure …` / `return match …` / `return run \`…\`(…)` build `Expr.call` / `Expr.ensure_call` / `Expr.match` / `Expr.inline_script` directly with no sidecar; `log run \`…\`(…)` and `logerr run \`…\`(…)` build `say` steps whose `message` is an `Expr.inline_script`. Downstream consumers compress accordingly: the validator switches on the 8-variant `WorkflowStepDef.type` and the 8-kind `Expr.kind` with no "literal value vs managed sidecar" fork; the formatter renders each `Expr` through one `emitExpr` helper instead of branching on a sidecar; the runtime has one private `evaluateExpr(scope, expr, …)` dispatcher that `const` / `return` / `send` / `say` / `exec` all delegate to (which runs the managed call for `call` / `ensure_call` / `inline_script`, walks `match` arms, schema-checks `prompt`, and interpolates `literal` via `interpolateWithCaptures`); the script-emit walk in `src/transpile/emit-script.ts` finds inline-script bodies by recursing into each step's `Expr` payload rather than enumerating the four legacy carriers. New tests pin the invariants: `src/types-shape.test.ts` is a compile-time exhaustive `switch` plus runtime tuple assertion that `WorkflowStepDef` has exactly **8** variants and `Expr` has exactly **8** kinds (AC2), a `grep` over every non-test `.ts` file under `src/` that fails if any of the placeholder strings (`"__match__"`, `"run inline_script"`, `"__JAIPH_MANAGED__"`) reappear (AC1), and an export-surface check that fails if `ConstRhs` or `SendRhsDef` are re-exported from `src/types.ts` (AC3). Updated parser tests in `src/parse/parse-return.test.ts`, `src/parse/parse-const-rhs.test.ts`, `src/parse/parse-prompt.test.ts`, `src/parse/parse-send-rhs.test.ts`, `src/parse/parse-steps.test.ts`, `src/parse/parse-inline-script.test.ts`, and `src/parse/parse-bare-call.test.ts` assert the new `Expr` shape directly for `return run …`, `return ensure …`, `return match … { … }`, `return run \`…\`(…)`, `log run \`…\`(…)`, and `const x = prompt …` (AC4). The golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`) passes byte-for-byte against the emitted bash output; `src/format/roundtrip.test.ts` round-trips bit-for-bit on every fixture; `npm run build` passes with zero TypeScript strict-mode errors (AC5 / AC6). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to reflect the new step shapes (`exec` wrapping every managed call, `say` replacing `log` / `logerr` / `fail`, `trivia` replacing `comment` / `blank_line`, `Expr` value/message/body payloads). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: surface syntax, the validator's deeper structural rewrite (Refactor 4), and parser internals (Refactors 1 & 2). Docs updated in `docs/architecture.md` (rewrote the **AST / Types** bullet to describe the single `Expr` sum and the 8-variant `WorkflowStepDef`; updated **Validator**, **Formatter**, **Node Workflow Runtime**, and **Trivia / CST layer** bullets to drop the dual-representation language; rewrote the `match_expr` mention in **CLI progress reporting pipeline** to use `Expr.kind === "match"`) and `docs/contributing.md` (new **`Expr` / step-variant shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 3. - **Refactor — Collapse `bareIdentifierArgs` into a typed `Arg[]` on every call site:** Every call-bearing AST node used to carry the call arguments twice — `args: string` (the raw source between the parens) and `bareIdentifierArgs?: string[]` (a re-parse of which of those arguments happened to be bare identifiers). The validator had to remember to check both fields and call a hand-rolled `validateBareIdentifierArgs` helper at every site; the emitter re-parsed `args` from scratch because it didn't trust either field on its own. Both fields are gone. The parser now classifies each argument once, at parse time, into a new typed sum `type Arg = { kind: "literal"; raw: string } | { kind: "var"; name: string }` and stores it on every call-bearing node as `args?: Arg[]`. Affected nodes: `run` / `ensure` workflow steps, `run_inline_script` steps, the `managed` sidecar on `return` / `log` / `logerr` (in all four shapes — `run`, `ensure`, `run_inline_script`, `match`), the `run_capture` / `ensure_capture` / `run_inline_script_capture` const RHS variants, and the `run` send RHS. Downstream consumers walk the typed list directly: the validator's per-call check sequence is now arity (`args.length`), shell-redirection rejection on `literal` raws, nested-unmanaged-call rejection on `literal` raws, ref resolution, and `var`-arg resolution against in-scope bindings via a new `validateArgVarRefs` (the standalone `validateBareIdentifierArgs` helper is deleted); the formatter renders each `Arg` directly (`var` → bare name, `literal` → raw) instead of re-tokenizing a `${ident}`-rewritten string; the runtime turns `Arg[]` back into the space-separated argv string via `argsToRuntimeString` in `src/parse/core.ts` (`var` → `${name}`, `literal` → raw) so the existing handle-resolution / interpolation path is unchanged. New tests pin the invariants: `src/parse/arg-ast-shape.test.ts` is a compile-time assertion that `bareIdentifierArgs` does not appear on `WorkflowStepDef` (`ensure`, `run`, `run_inline_script`, `log.managed`, `logerr.managed`, `return.managed` in `run` / `ensure` / `run_inline_script` shapes), `ConstRhs` (`run_capture`, `ensure_capture`, `run_inline_script_capture`), or the `run` `SendRhsDef` variant (AC1); `src/parse/arg-grep.test.ts` walks every non-test `.ts` under `src/parse/` and `src/transpile/` and fails if any production file matches `args.split(",")` or the bare token `bareIdentifierArgs` (AC2), and separately fails if any file under `src/transpile/` references `validateBareIdentifierArgs` (AC3). The golden compiler corpus, `validate-*.test.ts` files, and the golden AST corpus pass byte-for-byte (AC4); `npm run build` passes with zero TypeScript strict-mode errors (AC5). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the full `Expr` collapse (next task) and surface syntax. Docs updated in `docs/architecture.md` (extended **AST / Types** bullet documenting the typed `Arg` sum; updated **Validator** and **Formatter** bullets to drop the dual representation), `docs/contributing.md` (new **Call-args AST shape** row in the test-layer table), and `docs/spec-async-handles.md` (replaces the stale `commaArgsToSpaced` reference with `argsToRuntimeString`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix D. - **Refactor — Split source-fidelity data from the semantic AST into a `Trivia` (CST) layer:** Around ten fields whose only consumer was the formatter — `leadingComments` on imports / script imports / channels / `const` decls / `test` blocks, `configLeadingComments`, `trailingTopLevelComments`, `configBodySequence` (both module- and workflow-scoped), `topLevelOrder`, `bareSource` on `return`, the `tripleQuoted` flags on `literal` / `return` / `log` / `logerr` / `fail` / `send` / `const`, and the prompt / script `bodyKind` / `bodyIdentifier` discriminators — are removed from `jaiphModule`, `WorkflowStepDef`, `ConstRhs`, `SendRhsDef`, `WorkflowMetadata`, `ImportDef`, `ScriptImportDef`, `ChannelDef`, `ScriptDef`, and `TestBlockDef`, and re-homed in a new parallel `Trivia` store (`src/parse/trivia.ts`) keyed by AST-node identity (per-node `WeakMap`) plus a small `ModuleTrivia` record for module-level data. The parser exposes `parsejaiphWithTrivia(source, filePath) → { ast, trivia }`; the legacy `parsejaiph(source, filePath)` is now a thin wrapper that drops trivia for callers that don't care (validator, transpiler, runtime, `loadModuleGraph`). The formatter (`emitModule(ast, trivia, opts?)`) is the only consumer of `Trivia`; validator, emitter, transpiler, and runtime never import from `src/parse/trivia.ts`. New tests pin the invariants: `src/parse/trivia-ast-shape.test.ts` is a compile-time assertion (with runtime echo) that none of the listed fields reappear on any semantic AST type (AC1); `src/parse/trivia-grep.test.ts` greps validator and emitter source files and fails if any of them references `Trivia` / `createTrivia` / `NodeTrivia` / `ModuleTrivia` or imports from `parse/trivia` (AC2); `src/format/roundtrip.test.ts` walks every `.jh` under `examples/` and `test-fixtures/golden-ast/fixtures/` and asserts `parse → format → parse → format` converges bit-for-bit (AC3). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to drop the moved fields. User-visible contracts (CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming) are unchanged. `npm test` and `npm run build` pass with zero TypeScript strict-mode errors (AC4 / AC5). Out of scope: the `Expr` collapse — this refactor only relocates source-fidelity fields without changing the semantic AST's shape. Docs updated in `docs/architecture.md` (new **Trivia / CST layer** section with anchor `#trivia-cst-layer`, plus updated **Parser**, **AST / Types**, and **Formatter** bullets) and `docs/contributing.md` (new row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix A. - **Refactor — `ModuleGraph` is the single representation of "all `.jh` modules reachable from an entry point, parsed once":** The previous three traversal strategies for compile-time module discovery (validator re-reading imports through `ValidateContext`, `emitScriptsForModule` re-wrapping the same callbacks with an optional `prep` cache, and `buildScripts` walking the filesystem directly) collapse to one path. `parsejaiph(source, filePath)` is now strictly I/O-pure — it can no longer reach `fs`. The single discovery routine `loadModuleGraph(entry, workspaceRoot?)` (`src/transpile/module-graph.ts`) walks the entry plus its transitive `import` closure and returns `{ entryFile, workspaceRoot?, modules: Map }`; every other compile-time consumer takes the graph and never re-reads `.jh` from disk. `validateReferences(graph)` and `emitScriptsForModuleFromGraph(graph, file, rootDir)` operate entirely in-memory. The `ValidateContext` interface (`resolveImportPath` / `existsSync` / `readFile` / `parse` / `workspaceRoot` callbacks) is deleted from `src/transpile/validate.ts`; the validator consumes the graph and uses `existsSync` only to resolve `import script` paths (non-`.jh` bodies). `CompilePrep` / `prepareCompile` / `writeCompilePrep` / `readCompilePrep` and the optional `prep?` parameter on `emitScriptsForModule` / `buildScripts` are gone; `buildScripts(input, outDir, ws?)` now loads a graph internally and `buildScriptsFromGraph(graph, outDir, rootDir?)` is the entry point for callers that already loaded one. `buildRuntimeGraph` accepts either an entry file path (legacy) or an already-loaded `ModuleGraph` — `RuntimeGraph` is a type alias for `ModuleGraph` (the only "all reachable modules" representation in the codebase). The cross-process cache file moves to `/.jaiph-module-graph.json` (deterministic JSON: entries sorted by absolute path, ASTs included verbatim) via `writeModuleGraph` / `readModuleGraph`, and the internal env var the spawned `node-workflow-runner.js` reads is renamed `JAIPH_MODULE_GRAPH_FILE` (replacing `JAIPH_COMPILE_PREP_FILE`). Scope of the env-var hand-off is unchanged: set only for the default local non-Docker `jaiph run` path; `jaiph run --raw`, `jaiph test`, and Docker launches fall back to `loadModuleGraph` from the source file. User-visible contracts — banner, hooks, run artifacts, `run_summary.jsonl`, `return_value.txt`, exit codes, `__JAIPH_EVENT__` streaming, CLI usage, and the full golden corpus (`compiler-golden.test.ts`, `compiler-edge.acceptance.test.ts`) — are unchanged byte-for-byte. New tests (`src/transpile/module-graph.test.ts`, `src/transpile/pipeline-io-purity.test.ts`) stub `node:fs` to throw on any `.jh` read and run the full pipeline against `test-fixtures/` to pin the I/O-purity invariant; another test instruments `parsejaiph` with a call counter to assert no duplicate parses across `loadModuleGraph` → `validateReferences` → `emit` → `buildRuntimeGraph` for fixtures with transitive imports. `src/transpile/compile-prep.ts` and `compile-prep.test.ts` are removed.

the test is a `.jh` input paired with an expected outcome | | **Golden AST tests** | `test-fixtures/golden-ast/fixtures/*.jh` + `test-fixtures/golden-ast/expected/*.json` | Parse tree shape for successful parses — serialized to deterministic JSON with locations stripped (9 fixtures: e.g. imports, brace-if, log, match and match-multiline, params, prompt-capture, run-ensure, script-defs) | You changed the parser and need to verify the AST structure hasn't drifted; txtar tests only check pass/fail, goldens lock in the actual tree shape | | **Integration tests** | `integration/*.test.ts`, `integration/sample-build/*.test.ts` | Process-level integration behavior: signal handling, TTY rendering, run summary structure, sample builds | The test spans multiple modules or requires subprocess/PTY harnesses | diff --git a/src/cli/run/progress.test.ts b/src/cli/run/progress.test.ts index 92ab843a..6b29c01c 100644 --- a/src/cli/run/progress.test.ts +++ b/src/cli/run/progress.test.ts @@ -11,19 +11,15 @@ import { styleYellow, styleBold, } from "./progress";

The three pre-pass helpers are gone. A new walkStepTree descends the tree once, accumulating knownVars, promptSchemas (gated by withPromptSchemas so rules skip schema collection), and enforcing immutable-binding / script-collision rules inline through a shared bindings map (with a fresh inner map under each for_lines body so loop iterators only shadow inside the body). It emits a flat FlatStepEntry[] of every step in tree order with the enclosing catch / recover failure binding attached; the main per-workflow and per-rule validator loops iterate that flat list non-recursively. walkStepTree's internal descend is now the only recursive helper in the file that takes a WorkflowStepDef[]. All existing E_VALIDATE error messages and locations are preserved bit-for-bit. New tests in validate-single-walk.test.ts pin both invariants (no reappearance of the deleted helpers by name; at most one WorkflowStepDef[] walker). Docs updated.

The three pre-pass helpers are deleted. One new helper `walkStepTree(filePath, steps, envDecls, params, declLoc, moduleScripts, parseSchemaFieldNames, { withPromptSchemas })` descends the tree once and returns `{ knownVars, promptSchemas, flat }`: it accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings — workflow walks set `withPromptSchemas: true`, rule walks set it `false`), enforces immutable-binding and `script`-collision rules inline through a shared `bindings` map (with a fresh inner map under each `for_lines` body so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding (`recoverBindings: Set | undefined`) attached. The per-workflow and per-rule validator loops now iterate that flat list non-recursively — the `if` / `for_lines` / `catch` / `recover` recursion that used to live inside `validateStep` / `validateRuleStep` is gone. `walkStepTree`'s internal `descend` is the only recursive helper in the file that takes a `WorkflowStepDef[]`. Failure order matches the prior "binding errors first, then per-step errors" behavior because binding checks fire during the descent, before any flat-list iteration starts. Every existing `E_VALIDATE` error message and location is preserved bit-for-bit: the full `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New tests pin the invariants: `src/transpile/validate-single-walk.test.ts` greps `validate.ts` and fails if any of `collectKnownVars`, `collectPromptSchemas`, or `validateImmutableBindings` reappear by name (AC1), and a textual AST scan asserts that at most one recursive helper whose parameter list mentions `WorkflowStepDef[]` exists in the file (AC2). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the visitor-table refactor (Refactor 4) and any change to validation rules. Docs updated in `docs/architecture.md` (new **Single workflow walk** bullet under **Validator**) and `docs/contributing.md` (new **Validator single-walk shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix C. - **Refactor — Collapse the AST around a single `Expr` type, eliminating the three "managed call" encodings:** The same concept "a managed call that yields a value" used to be encoded three different ways: as a statement (`{ type: "run", workflow, args }`), as a const RHS (`{ kind: "run_capture", ref, args }`), and as a `managed:` sidecar on `return` / `log` / `logerr` whose `value` / `message` carried a placeholder string (`"__match__"`, `"run inline_script"`, etc.). Inline scripts added a fourth (`run_inline_script_capture`); `prompt`, `match`, and `ensure` captures repeated the same dual representation. The validator, formatter, emitter, and runtime each had to handle both branches at every site. All three encodings are gone. The semantic AST now has a single `Expr` tagged union — `literal | call | ensure_call | inline_script | prompt | match | shell | bare_ref` — used everywhere a value can appear: `const name = `, `return `, `send channel <- `, the message of `log` / `logerr` / `fail`, and the body of an `exec` step (the new statement-form managed call, where the value is consumed for its side effects plus optional capture). `ConstRhs` and `SendRhsDef` are deleted as separate types. The `managed:` sidecar field is deleted from `WorkflowStepDef`. The placeholder strings `"__match__"`, `"run inline_script"`, and `"__JAIPH_MANAGED__"` no longer appear anywhere under `src/`. `WorkflowStepDef` collapses from 14 variants to **8** (`exec`, `const`, `return`, `send`, `say`, `if`, `for_lines`, `trivia`): `exec` is the new managed-statement form covering the prior `run` / `ensure` / `run_inline_script` / `prompt` / `shell` / standalone `match` cases (the discriminator now lives inside `body.kind`, with `captureName` / `catch` / `recover` as step-level attributes); `say` covers the prior `log` / `logerr` / `fail` cases (`level: "fail"` aborts the workflow with the message, otherwise the message is written to the corresponding stream); `comment` / `blank_line` collapse into a single `trivia` variant (formatter-only, skipped by validator and runtime). The parser builds `Expr` nodes directly: `parseConstRhs` returns `{ value: Expr }`; `parseSendRhs` returns `{ value: Expr }`; `parsePromptStep` returns an `exec` step whose `body` is an `Expr.prompt`; `return run …` / `return ensure …` / `return match …` / `return run \`…\`(…)` build `Expr.call` / `Expr.ensure_call` / `Expr.match` / `Expr.inline_script` directly with no sidecar; `log run \`…\`(…)` and `logerr run \`…\`(…)` build `say` steps whose `message` is an `Expr.inline_script`. Downstream consumers compress accordingly: the validator switches on the 8-variant `WorkflowStepDef.type` and the 8-kind `Expr.kind` with no "literal value vs managed sidecar" fork; the formatter renders each `Expr` through one `emitExpr` helper instead of branching on a sidecar; the runtime has one private `evaluateExpr(scope, expr, …)` dispatcher that `const` / `return` / `send` / `say` / `exec` all delegate to (which runs the managed call for `call` / `ensure_call` / `inline_script`, walks `match` arms, schema-checks `prompt`, and interpolates `literal` via `interpolateWithCaptures`); the script-emit walk in `src/transpile/emit-script.ts` finds inline-script bodies by recursing into each step's `Expr` payload rather than enumerating the four legacy carriers. New tests pin the invariants: `src/types-shape.test.ts` is a compile-time exhaustive `switch` plus runtime tuple assertion that `WorkflowStepDef` has exactly **8** variants and `Expr` has exactly **8** kinds (AC2), a `grep` over every non-test `.ts` file under `src/` that fails if any of the placeholder strings (`"__match__"`, `"run inline_script"`, `"__JAIPH_MANAGED__"`) reappear (AC1), and an export-surface check that fails if `ConstRhs` or `SendRhsDef` are re-exported from `src/types.ts` (AC3). Updated parser tests in `src/parse/parse-return.test.ts`, `src/parse/parse-const-rhs.test.ts`, `src/parse/parse-prompt.test.ts`, `src/parse/parse-send-rhs.test.ts`, `src/parse/parse-steps.test.ts`, `src/parse/parse-inline-script.test.ts`, and `src/parse/parse-bare-call.test.ts` assert the new `Expr` shape directly for `return run …`, `return ensure …`, `return match … { … }`, `return run \`…\`(…)`, `log run \`…\`(…)`, and `const x = prompt …` (AC4). The golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`) passes byte-for-byte against the emitted bash output; `src/format/roundtrip.test.ts` round-trips bit-for-bit on every fixture; `npm run build` passes with zero TypeScript strict-mode errors (AC5 / AC6). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to reflect the new step shapes (`exec` wrapping every managed call, `say` replacing `log` / `logerr` / `fail`, `trivia` replacing `comment` / `blank_line`, `Expr` value/message/body payloads). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: surface syntax, the validator's deeper structural rewrite (Refactor 4), and parser internals (Refactors 1 & 2). Docs updated in `docs/architecture.md` (rewrote the **AST / Types** bullet to describe the single `Expr` sum and the 8-variant `WorkflowStepDef`; updated **Validator**, **Formatter**, **Node Workflow Runtime**, and **Trivia / CST layer** bullets to drop the dual-representation language; rewrote the `match_expr` mention in **CLI progress reporting pipeline** to use `Expr.kind === "match"`) and `docs/contributing.md` (new **`Expr` / step-variant shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 3. - **Refactor — Collapse `bareIdentifierArgs` into a typed `Arg[]` on every call site:** Every call-bearing AST node used to carry the call arguments twice — `args: string` (the raw source between the parens) and `bareIdentifierArgs?: string[]` (a re-parse of which of those arguments happened to be bare identifiers). The validator had to remember to check both fields and call a hand-rolled `validateBareIdentifierArgs` helper at every site; the emitter re-parsed `args` from scratch because it didn't trust either field on its own. Both fields are gone. The parser now classifies each argument once, at parse time, into a new typed sum `type Arg = { kind: "literal"; raw: string } | { kind: "var"; name: string }` and stores it on every call-bearing node as `args?: Arg[]`. Affected nodes: `run` / `ensure` workflow steps, `run_inline_script` steps, the `managed` sidecar on `return` / `log` / `logerr` (in all four shapes — `run`, `ensure`, `run_inline_script`, `match`), the `run_capture` / `ensure_capture` / `run_inline_script_capture` const RHS variants, and the `run` send RHS. Downstream consumers walk the typed list directly: the validator's per-call check sequence is now arity (`args.length`), shell-redirection rejection on `literal` raws, nested-unmanaged-call rejection on `literal` raws, ref resolution, and `var`-arg resolution against in-scope bindings via a new `validateArgVarRefs` (the standalone `validateBareIdentifierArgs` helper is deleted); the formatter renders each `Arg` directly (`var` → bare name, `literal` → raw) instead of re-tokenizing a `${ident}`-rewritten string; the runtime turns `Arg[]` back into the space-separated argv string via `argsToRuntimeString` in `src/parse/core.ts` (`var` → `${name}`, `literal` → raw) so the existing handle-resolution / interpolation path is unchanged. New tests pin the invariants: `src/parse/arg-ast-shape.test.ts` is a compile-time assertion that `bareIdentifierArgs` does not appear on `WorkflowStepDef` (`ensure`, `run`, `run_inline_script`, `log.managed`, `logerr.managed`, `return.managed` in `run` / `ensure` / `run_inline_script` shapes), `ConstRhs` (`run_capture`, `ensure_capture`, `run_inline_script_capture`), or the `run` `SendRhsDef` variant (AC1); `src/parse/arg-grep.test.ts` walks every non-test `.ts` under `src/parse/` and `src/transpile/` and fails if any production file matches `args.split(",")` or the bare token `bareIdentifierArgs` (AC2), and separately fails if any file under `src/transpile/` references `validateBareIdentifierArgs` (AC3). The golden compiler corpus, `validate-*.test.ts` files, and the golden AST corpus pass byte-for-byte (AC4); `npm run build` passes with zero TypeScript strict-mode errors (AC5). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the full `Expr` collapse (next task) and surface syntax. Docs updated in `docs/architecture.md` (extended **AST / Types** bullet documenting the typed `Arg` sum; updated **Validator** and **Formatter** bullets to drop the dual representation), `docs/contributing.md` (new **Call-args AST shape** row in the test-layer table), and `docs/spec-async-handles.md` (replaces the stale `commaArgsToSpaced` reference with `argsToRuntimeString`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix D. - **Refactor — Split source-fidelity data from the semantic AST into a `Trivia` (CST) layer:** Around ten fields whose only consumer was the formatter — `leadingComments` on imports / script imports / channels / `const` decls / `test` blocks, `configLeadingComments`, `trailingTopLevelComments`, `configBodySequence` (both module- and workflow-scoped), `topLevelOrder`, `bareSource` on `return`, the `tripleQuoted` flags on `literal` / `return` / `log` / `logerr` / `fail` / `send` / `const`, and the prompt / script `bodyKind` / `bodyIdentifier` discriminators — are removed from `jaiphModule`, `WorkflowStepDef`, `ConstRhs`, `SendRhsDef`, `WorkflowMetadata`, `ImportDef`, `ScriptImportDef`, `ChannelDef`, `ScriptDef`, and `TestBlockDef`, and re-homed in a new parallel `Trivia` store (`src/parse/trivia.ts`) keyed by AST-node identity (per-node `WeakMap`) plus a small `ModuleTrivia` record for module-level data. The parser exposes `parsejaiphWithTrivia(source, filePath) → { ast, trivia }`; the legacy `parsejaiph(source, filePath)` is now a thin wrapper that drops trivia for callers that don't care (validator, transpiler, runtime, `loadModuleGraph`). The formatter (`emitModule(ast, trivia, opts?)`) is the only consumer of `Trivia`; validator, emitter, transpiler, and runtime never import from `src/parse/trivia.ts`. New tests pin the invariants: `src/parse/trivia-ast-shape.test.ts` is a compile-time assertion (with runtime echo) that none of the listed fields reappear on any semantic AST type (AC1); `src/parse/trivia-grep.test.ts` greps validator and emitter source files and fails if any of them references `Trivia` / `createTrivia` / `NodeTrivia` / `ModuleTrivia` or imports from `parse/trivia` (AC2); `src/format/roundtrip.test.ts` walks every `.jh` under `examples/` and `test-fixtures/golden-ast/fixtures/` and asserts `parse → format → parse → format` converges bit-for-bit (AC3). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to drop the moved fields. User-visible contracts (CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming) are unchanged. `npm test` and `npm run build` pass with zero TypeScript strict-mode errors (AC4 / AC5). Out of scope: the `Expr` collapse — this refactor only relocates source-fidelity fields without changing the semantic AST's shape. Docs updated in `docs/architecture.md` (new **Trivia / CST layer** section with anchor `#trivia-cst-layer`, plus updated **Parser**, **AST / Types**, and **Formatter** bullets) and `docs/contributing.md` (new row in the test-layer table).

The main per-step validator loop iterates that flat list non-recursively, so `walkStepTree`'s internal `descend` is the **only** recursive helper in the file that takes a `WorkflowStepDef[]`. A pair of grep / AST tests (`src/transpile/validate-single-walk.test.ts`) pins both invariants: the prior helpers (`collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`) cannot reappear by name, and at most one recursive `WorkflowStepDef[]` walker may live in `validate.ts`. - Per call site the validator runs five checks against the typed **`Arg[]`** directly — shell-redirection rejection (only `literal` args are scanned), nested-unmanaged-call rejection inside `literal` raws, ref resolution, arity (`args.length` vs declared params), and `var`-arg resolution against in-scope bindings via `validateArgVarRefs`.

Each top-level validation unit (per-import block, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step, per-channel route) is wrapped in `diag.capture(fn)` so a bailout from one error unwinds only that unit; the four leaf helpers (validate-ref-resolution, validate-string, validate-prompt-schema, shell-jaiph-guard) still throw and every caller captures them. `jaiph compile` routes through `collectDiagnostics`, prints the full sorted set (stderr lines or a single JSON array under `--json`), and exits non-zero on any non-empty set. New tests in `src/transpile/diagnostics-collector.test.ts` pin all five acceptance criteria, including a three-error fixture and a source-tree allowlist scan over remaining `throw jaiphError(` sites.

The validator also pre-ordered some checks defensively because it knew it would only get to surface one error per run. That model is replaced. A new `Diagnostics` class lives in `src/diagnostics.ts` and exposes `add(d)`, `error(file, line, col, code, message)` (records the diagnostic and short-circuits the current unit through a `BailoutError`), `capture(fn)` (runs `fn` and absorbs both `BailoutError` and any thrown legacy `jaiphError` whose message parses as `path:line:col CODE message` — turning the throw into a recoverable entry without re-throwing), `hasErrors()` / `hasFatal()`, `sorted()` (stable order by file, then line, then column), `formatLines()` (one `path:line:col CODE message` per line), and a legacy `throwFirstIfAny()` bridge that throws the first sorted diagnostic via `jaiphError` so existing single-error call sites and per-error tests are unchanged. `src/transpile/validate.ts` exposes a new `collectDiagnostics(graph): Diagnostics` entry that walks the import closure and never throws on user-level errors; the previous `validateReferences(graph)` is now a thin wrapper that calls `collectDiagnostics` and then `throwFirstIfAny()`, preserving the throw-on-first contract for `emitScriptsForModuleFromGraph` / `buildScriptsFromGraph` and for every existing `parse-*.test.ts` / `validate-*.test.ts` fixture that asserts one specific `{ message, line, col, code }`. Inside `validate.ts` every `throw jaiphError(...)` site at user-level (~50 sites across import resolution, channel-route validation, per-rule and per-workflow step walks, prompt schema checks, and `validateTestBlocks`) is migrated to `diag.error(...)`; each top-level unit is wrapped in `diag.capture(...)` (per-import block, per-channel route, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step) so the bailout from one error unwinds only that unit and the next sibling still runs. The four leaf validation helpers (`validate-ref-resolution.ts`, `validate-string.ts`, `validate-prompt-schema.ts`, `shell-jaiph-guard.ts`) still throw via `jaiphError`, but every caller wraps them in `diag.capture(...)`, which converts the thrown error into a recoverable diagnostic and returns. The CLI command `jaiph compile` (`src/cli/commands/compile.ts`) is rewritten to route through `collectDiagnostics`: it accumulates every error from every entry's import closure, sorts them by `(file, line, col)`, and prints the full set — as a single JSON array on stdout under `--json`, or as one `path:line:col CODE message` line per diagnostic on stderr otherwise — exiting **1** on any non-empty diagnostic set. Fatal aborts during graph load or parsing (unterminated triple-quote, unterminated brace block, missing imports during graph build) are reported as a single diagnostic for the affected entry; the command then continues with the next entry. New tests in `src/transpile/diagnostics-collector.test.ts` pin the invariants: a fixture with three independent errors (duplicate import alias, undefined channel, unknown `run` target in one workflow body) asserts `collectDiagnostics(graph)` returns all three in source order (AC1); a source-tree scan asserts `validate.ts` holds **zero** `throw jaiphError(` sites and **≥40** `diag.error(` sites, and that every remaining `throw jaiphError(` under `src/` lives in the documented fatal allowlist — `src/diagnostics.ts` (legacy bridge), `src/parse/core.ts` (parser `fail()`), `src/cli/commands/test.ts` (test-file shape fatal), `src/transpile/module-graph.ts` (loader), `src/transpile/validate-string.ts`, `src/transpile/validate-prompt-schema.ts`, `src/transpile/validate-ref-resolution.ts`, `src/transpile/shell-jaiph-guard.ts` (leaf helpers, each captured) (AC3); and a CLI test runs `jaiph compile --json` against the same fixture and asserts the returned array has all three diagnostics and `status !== 0` (AC4). Existing single-error tests (every `parse-*.test.ts` and `validate-*.test.ts` that pins one specific `{ message, line, col, code }`) still pass because `validateReferences` continues to throw the first sorted diagnostic (AC2); `npm test` and `npm run build` pass (AC5). User-visible contracts on the `jaiph run` / `jaiph test` paths — banner, hooks, run artifacts, exit codes, `__JAIPH_EVENT__` streaming, and golden corpus — are unchanged. Out of scope: changing what counts as an error (this refactor only changes the *how*); LSP integration follows in a separate task. Docs updated in `docs/architecture.md` (new **Diagnostics collector (recoverable errors)** bullet under **Validator**; updated **System overview** to describe the two entry points and the new `jaiph compile` behavior), `docs/cli.md` (new **Multiple-error reporting** paragraph and refined **`--json`** description under **`jaiph compile`**), and `docs/contributing.md` (new **Diagnostics collector shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix B. - **Refactor — Fold the validator's three workflow pre-passes into a single step-tree walk:** `src/transpile/validate.ts` used to descend each workflow's / rule's step tree four times before its main check loop finished — `collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`, and the per-step validator itself — each re-implementing the same recursion over `if` / `for_lines` / `catch` / `recover` with subtly different rules, so "what counts as a binding here" fixes had to land in two or three walkers. The three pre-pass helpers are deleted. One new helper `walkStepTree(filePath, steps, envDecls, params, declLoc, moduleScripts, parseSchemaFieldNames, { withPromptSchemas })` descends the tree once and returns `{ knownVars, promptSchemas, flat }`: it accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings — workflow walks set `withPromptSchemas: true`, rule walks set it `false`), enforces immutable-binding and `script`-collision rules inline through a shared `bindings` map (with a fresh inner map under each `for_lines` body so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding (`recoverBindings: Set | undefined`) attached. The per-workflow and per-rule validator loops now iterate that flat list non-recursively — the `if` / `for_lines` / `catch` / `recover` recursion that used to live inside `validateStep` / `validateRuleStep` is gone. `walkStepTree`'s internal `descend` is the only recursive helper in the file that takes a `WorkflowStepDef[]`. Failure order matches the prior "binding errors first, then per-step errors" behavior because binding checks fire during the descent, before any flat-list iteration starts. Every existing `E_VALIDATE` error message and location is preserved bit-for-bit: the full `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New tests pin the invariants: `src/transpile/validate-single-walk.test.ts` greps `validate.ts` and fails if any of `collectKnownVars`, `collectPromptSchemas`, or `validateImmutableBindings` reappear by name (AC1), and a textual AST scan asserts that at most one recursive helper whose parameter list mentions `WorkflowStepDef[]` exists in the file (AC2). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the visitor-table refactor (Refactor 4) and any change to validation rules. Docs updated in `docs/architecture.md` (new **Single workflow walk** bullet under **Validator**) and `docs/contributing.md` (new **Validator single-walk shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix C. - **Refactor — Collapse the AST around a single `Expr` type, eliminating the three "managed call" encodings:** The same concept "a managed call that yields a value" used to be encoded three different ways: as a statement (`{ type: "run", workflow, args }`), as a const RHS (`{ kind: "run_capture", ref, args }`), and as a `managed:` sidecar on `return` / `log` / `logerr` whose `value` / `message` carried a placeholder string (`"__match__"`, `"run inline_script"`, etc.). Inline scripts added a fourth (`run_inline_script_capture`); `prompt`, `match`, and `ensure` captures repeated the same dual representation. The validator, formatter, emitter, and runtime each had to handle both branches at every site. All three encodings are gone. The semantic AST now has a single `Expr` tagged union — `literal | call | ensure_call | inline_script | prompt | match | shell | bare_ref` — used everywhere a value can appear: `const name = `, `return `, `send channel <- `, the message of `log` / `logerr` / `fail`, and the body of an `exec` step (the new statement-form managed call, where the value is consumed for its side effects plus optional capture). `ConstRhs` and `SendRhsDef` are deleted as separate types. The `managed:` sidecar field is deleted from `WorkflowStepDef`. The placeholder strings `"__match__"`, `"run inline_script"`, and `"__JAIPH_MANAGED__"` no longer appear anywhere under `src/`. `WorkflowStepDef` collapses from 14 variants to **8** (`exec`, `const`, `return`, `send`, `say`, `if`, `for_lines`, `trivia`): `exec` is the new managed-statement form covering the prior `run` / `ensure` / `run_inline_script` / `prompt` / `shell` / standalone `match` cases (the discriminator now lives inside `body.kind`, with `captureName` / `catch` / `recover` as step-level attributes); `say` covers the prior `log` / `logerr` / `fail` cases (`level: "fail"` aborts the workflow with the message, otherwise the message is written to the corresponding stream); `comment` / `blank_line` collapse into a single `trivia` variant (formatter-only, skipped by validator and runtime). The parser builds `Expr` nodes directly: `parseConstRhs` returns `{ value: Expr }`; `parseSendRhs` returns `{ value: Expr }`; `parsePromptStep` returns an `exec` step whose `body` is an `Expr.prompt`; `return run …` / `return ensure …` / `return match …` / `return run \`…\`(…)` build `Expr.call` / `Expr.ensure_call` / `Expr.match` / `Expr.inline_script` directly with no sidecar; `log run \`…\`(…)` and `logerr run \`…\`(…)` build `say` steps whose `message` is an `Expr.inline_script`. Downstream consumers compress accordingly: the validator switches on the 8-variant `WorkflowStepDef.type` and the 8-kind `Expr.kind` with no "literal value vs managed sidecar" fork; the formatter renders each `Expr` through one `emitExpr` helper instead of branching on a sidecar; the runtime has one private `evaluateExpr(scope, expr, …)` dispatcher that `const` / `return` / `send` / `say` / `exec` all delegate to (which runs the managed call for `call` / `ensure_call` / `inline_script`, walks `match` arms, schema-checks `prompt`, and interpolates `literal` via `interpolateWithCaptures`); the script-emit walk in `src/transpile/emit-script.ts` finds inline-script bodies by recursing into each step's `Expr` payload rather than enumerating the four legacy carriers. New tests pin the invariants: `src/types-shape.test.ts` is a compile-time exhaustive `switch` plus runtime tuple assertion that `WorkflowStepDef` has exactly **8** variants and `Expr` has exactly **8** kinds (AC2), a `grep` over every non-test `.ts` file under `src/` that fails if any of the placeholder strings (`"__match__"`, `"run inline_script"`, `"__JAIPH_MANAGED__"`) reappear (AC1), and an export-surface check that fails if `ConstRhs` or `SendRhsDef` are re-exported from `src/types.ts` (AC3). Updated parser tests in `src/parse/parse-return.test.ts`, `src/parse/parse-const-rhs.test.ts`, `src/parse/parse-prompt.test.ts`, `src/parse/parse-send-rhs.test.ts`, `src/parse/parse-steps.test.ts`, `src/parse/parse-inline-script.test.ts`, and `src/parse/parse-bare-call.test.ts` assert the new `Expr` shape directly for `return run …`, `return ensure …`, `return match … { … }`, `return run \`…\`(…)`, `log run \`…\`(…)`, and `const x = prompt …` (AC4). The golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`) passes byte-for-byte against the emitted bash output; `src/format/roundtrip.test.ts` round-trips bit-for-bit on every fixture; `npm run build` passes with zero TypeScript strict-mode errors (AC5 / AC6). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to reflect the new step shapes (`exec` wrapping every managed call, `say` replacing `log` / `logerr` / `fail`, `trivia` replacing `comment` / `blank_line`, `Expr` value/message/body payloads). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: surface syntax, the validator's deeper structural rewrite (Refactor 4), and parser internals (Refactors 1 & 2). Docs updated in `docs/architecture.md` (rewrote the **AST / Types** bullet to describe the single `Expr` sum and the 8-variant `WorkflowStepDef`; updated **Validator**, **Formatter**, **Node Workflow Runtime**, and **Trivia / CST layer** bullets to drop the dual-representation language; rewrote the `match_expr` mention in **CLI progress reporting pipeline** to use `Expr.kind === "match"`) and `docs/contributing.md` (new **`Expr` / step-variant shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 3. - **Refactor — Collapse `bareIdentifierArgs` into a typed `Arg[]` on every call site:** Every call-bearing AST node used to carry the call arguments twice — `args: string` (the raw source between the parens) and `bareIdentifierArgs?: string[]` (a re-parse of which of those arguments happened to be bare identifiers). The validator had to remember to check both fields and call a hand-rolled `validateBareIdentifierArgs` helper at every site; the emitter re-parsed `args` from scratch because it didn't trust either field on its own. Both fields are gone. The parser now classifies each argument once, at parse time, into a new typed sum `type Arg = { kind: "literal"; raw: string } | { kind: "var"; name: string }` and stores it on every call-bearing node as `args?: Arg[]`. Affected nodes: `run` / `ensure` workflow steps, `run_inline_script` steps, the `managed` sidecar on `return` / `log` / `logerr` (in all four shapes — `run`, `ensure`, `run_inline_script`, `match`), the `run_capture` / `ensure_capture` / `run_inline_script_capture` const RHS variants, and the `run` send RHS. Downstream consumers walk the typed list directly: the validator's per-call check sequence is now arity (`args.length`), shell-redirection rejection on `literal` raws, nested-unmanaged-call rejection on `literal` raws, ref resolution, and `var`-arg resolution against in-scope bindings via a new `validateArgVarRefs` (the standalone `validateBareIdentifierArgs` helper is deleted); the formatter renders each `Arg` directly (`var` → bare name, `literal` → raw) instead of re-tokenizing a `${ident}`-rewritten string; the runtime turns `Arg[]` back into the space-separated argv string via `argsToRuntimeString` in `src/parse/core.ts` (`var` → `${name}`, `literal` → raw) so the existing handle-resolution / interpolation path is unchanged. New tests pin the invariants: `src/parse/arg-ast-shape.test.ts` is a compile-time assertion that `bareIdentifierArgs` does not appear on `WorkflowStepDef` (`ensure`, `run`, `run_inline_script`, `log.managed`, `logerr.managed`, `return.managed` in `run` / `ensure` / `run_inline_script` shapes), `ConstRhs` (`run_capture`, `ensure_capture`, `run_inline_script_capture`), or the `run` `SendRhsDef` variant (AC1); `src/parse/arg-grep.test.ts` walks every non-test `.ts` under `src/parse/` and `src/transpile/` and fails if any production file matches `args.split(",")` or the bare token `bareIdentifierArgs` (AC2), and separately fails if any file under `src/transpile/` references `validateBareIdentifierArgs` (AC3). The golden compiler corpus, `validate-*.test.ts` files, and the golden AST corpus pass byte-for-byte (AC4); `npm run build` passes with zero TypeScript strict-mode errors (AC5). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the full `Expr` collapse (next task) and surface syntax. Docs updated in `docs/architecture.md` (extended **AST / Types** bullet documenting the typed `Arg` sum; updated **Validator** and **Formatter** bullets to drop the dual representation), `docs/contributing.md` (new **Call-args AST shape** row in the test-layer table), and `docs/spec-async-handles.md` (replaces the stale `commaArgsToSpaced` reference with `argsToRuntimeString`).

The **`jaiph compile`** command walks the same import closure but routes through `collectDiagnostics`: it builds a graph per entry, collects diagnostics, prints them all (sorted by file/line/col, in `path:line:col CODE message` form on stderr — or as a single JSON array on stdout with `--json`), and exits non-zero if any diagnostic was collected.

Export visibility is enforced by `validateRef` in `validate-ref-resolution.ts`: if an imported module declares any `export`, only exported names are reachable through the import alias. + - **Diagnostics collector (recoverable errors).** The validator no longer fails fast on the first user-level error. Every recoverable check appends to a `Diagnostics` collector (`src/diagnostics.ts`) via `diag.error(file, line, col, code, msg)`, which records a `JaiphDiagnostic` and short-circuits the current validation unit through a `BailoutError`. Each top-level unit (per-import block, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step, per-channel route) is wrapped in `diag.capture(fn)`, which absorbs the bailout (and any thrown `jaiphError` from leaf helpers like `validate-ref-resolution.ts` / `validate-string.ts` / `validate-prompt-schema.ts` / `shell-jaiph-guard.ts`) so the next sibling unit still runs. `collectDiagnostics(graph)` walks every module and returns the populated collector; the legacy `validateReferences(graph)` is now a thin wrapper that throws the first sorted diagnostic via `jaiphError` so existing per-error tests and the `emitScriptsForModuleFromGraph` path keep working unchanged. `Diagnostics.sorted()` returns errors ordered by `(file, line, col)`; `formatLines()` renders the standard `path:line:col CODE message` shape. A grep test (`src/transpile/diagnostics-collector.test.ts`) pins the migration: `validate.ts` holds **zero** `throw jaiphError(` sites, and the remaining `throw jaiphError(` call sites under `src/` are confined to a documented allowlist — fatal aborts in the parser (`src/parse/core.ts`), the loader (`src/transpile/module-graph.ts`), and the test-file shape check (`src/cli/commands/test.ts`); the legacy bridge in `src/diagnostics.ts`; and the four leaf validation helpers above, each of which has every caller wrapped in `diag.capture(...)`. - The validator drives off `WorkflowStepDef.type` (8 variants) and `Expr.kind` (8 variants). For every value-bearing step (`const` / `return` / `send` / `say`) and for the body of every `exec` step, a single `validateExpr(expr, ...)` dispatcher handles the value: it routes `call` / `ensure_call` / `inline_script` to call-site validation, walks `match` arms, schema-checks `prompt`, and runs the substitution scanner on `literal` raws. There is no dual code path for "managed sidecar vs literal value" — that branch is gone. - **Single workflow walk.** Each workflow / rule has its step tree descended exactly once by `walkStepTree`, which simultaneously accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings, gated by `options.withPromptSchemas` so rules skip schema collection), enforces immutable-binding / `script`-collision rules inline (mutating a shared `bindings` map and threading a fresh inner map under each `for_lines` so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding attached. The main per-step validator loop iterates that flat list non-recursively, so `walkStepTree`'s internal `descend` is the **only** recursive helper in the file that takes a `WorkflowStepDef[]`. A pair of grep / AST tests (`src/transpile/validate-single-walk.test.ts`) pins both invariants: the prior helpers (`collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`) cannot reappear by name, and at most one recursive `WorkflowStepDef[]` walker may live in `validate.ts`. - Per call site the validator runs five checks against the typed **`Arg[]`** directly — shell-redirection rejection (only `literal` args are scanned), nested-unmanaged-call rejection inside `literal` raws, ref resolution, arity (`args.length` vs declared params), and `var`-arg resolution against in-scope bindings via `validateArgVarRefs`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the 1,441-LoC validate.ts monolith — two near-identical inner walkers (validateRuleStep, validateStep) plus the five-check call-shape sequence repeated at 12+ sites — with a two-file split. validate.ts (~430 LoC) keeps the outer layer: import / channel-route / test-block checks and walkStepTree (the single descent that builds knownVars, promptSchemas, and the flat step list). validate-step.ts (~1,025 LoC) holds the per-step visitor: one validateStep(step, ctx) entry, a VALIDATORS: Record table with one row per variant, a validateExpr(expr, ...) dispatcher over the 8 Expr.kind values, and a single validateCallable(expr, ctx) helper that runs the five managed-call-shape checks once for both call (run) and ensure_call (ensure). Rule-vs-workflow differences are captured in a Scope value (WORKFLOW_SCOPE / RULE_SCOPE) with allowSteps (single set-lookup gate at the top of validateStep), runRefExpect, and withPromptSchemas. Every E_VALIDATE message and source location is preserved bit-for-bit. New tests in validate-visitor.test.ts pin the invariants: a ≤700-line cap on validate.ts (AC1), a JSON snapshot over every validate-* txtar fixture asserting each diagnostic's { code, line, col, message } bit-for-bit (AC3), and an "unknown step type" test asserting a synthetic variant produces exactly one internal: no validator for step type "…" diagnostic in both scopes (AC4). The diagnostics-collector fatal-allowlist test now sums throw jaiphError / diag.error counts across both files. Docs updated in docs/architecture.md, docs/contributing.md, and docs/grammar.md.

Both inner walkers and every duplicated check site are gone. The validator now spans two files. `validate.ts` (~430 LoC) keeps the **outer** layer: import / channel-route / test-block checks and `walkStepTree` (the single descent that builds `{ knownVars, promptSchemas, flat }`). `validate-step.ts` (~1,025 LoC) holds the **per-step** visitor: a single `validateStep(step, ctx)` entry, a `VALIDATORS: Record` table with one row per step variant (`trivia`, `const`, `return`, `send`, `say`, `exec`, `if`, `for_lines`), one `validateExpr(expr, …)` dispatcher over the 8 `Expr.kind` values, and one `validateCallable(expr, ctx)` helper that runs the five managed-call-shape checks once for both `call` (`run`) and `ensure_call` (`ensure`) — parameterized by the scope's `runRefExpect` and the target kind. Rule-vs-workflow differences are captured in a `Scope` value (`WORKFLOW_SCOPE` / `RULE_SCOPE`) with three fields: `allowSteps: Set` (single set-lookup gate at the top of `validateStep` — rules reject `send` outright; rules also reject `prompt` and `run async` from inside `exec` bodies), `runRefExpect: RefExpectMessages` (workflow vs rule semantics for `run ref(…)`), and `withPromptSchemas: boolean` (workflows collect prompt-returning bindings, rules skip schema collection). `ValidatorCtx` threads the scope plus the precomputed `knownVars`, `promptSchemas`, and `recoverBindings` into every visitor — none of which are re-derived per step. Every existing `E_VALIDATE` error message and source location is preserved bit-for-bit: the entire `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New acceptance tests in `src/transpile/validate-visitor.test.ts` pin the invariants: an LoC test caps `validate.ts` at **≤700 lines** so new per-step logic lands in `validate-step.ts` (AC1); a JSON snapshot over every `validate-*` txtar fixture (`test-fixtures/compiler-txtar/validate-errors.txt` + `validate-errors-multi-module.txt`) stored in `test-fixtures/compiler-txtar/validate-diagnostics-snapshot.json` asserts each diagnostic's `{ code, line, col, message }` against `collectDiagnostics(graph)` bit-for-bit (AC3 — refreshable via `UPDATE_SNAPSHOTS=1` only after confirming the message change is intentional); and an "unknown step type" test casts a synthetic step variant into `WorkflowStepDef`, runs `validateStep` in both `WORKFLOW_SCOPE` and `RULE_SCOPE`, and asserts each call produces exactly one diagnostic with the documented `internal: no validator for step type "…"` message (AC4 — proving that adding a new step type costs exactly one row in `VALIDATORS`). The existing `src/transpile/validate-single-walk.test.ts` still passes — `walkStepTree`'s internal `descend` remains the only recursive `WorkflowStepDef[]` walker in `validate.ts` (AC2). The `diagnostics-collector.test.ts` "fatal allowlist" scan now sums `throw jaiphError(` counts across `validate.ts` + `validate-step.ts` (both files are zero) and `diag.error(` counts likewise (≥40). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: changes to validation rules (the *what* — this refactor only changes the *how*), parser changes, AST changes. Docs updated in `docs/architecture.md` (rewrote the **Validator** section to describe the two-file split, `VALIDATORS` table, `Scope` value, and the single `validateCallable` helper), `docs/contributing.md` (new **Validator visitor-table shape** row in the test-layer table), and `docs/grammar.md` (refreshed two stale `validateRuleStep` references to point at the new visitor / `RULE_SCOPE`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 4. - **Refactor — Replace fail-fast errors with a `Diagnostics` collector that aggregates every recoverable error per compile:** Today `fail()` (in `src/parse/core.ts`) and `jaiphError()` (in `src/errors.ts`) both throw on the first error, so a user fixed one error, recompiled, hit the next, recompiled, and so on. The validator also pre-ordered some checks defensively because it knew it would only get to surface one error per run. That model is replaced. A new `Diagnostics` class lives in `src/diagnostics.ts` and exposes `add(d)`, `error(file, line, col, code, message)` (records the diagnostic and short-circuits the current unit through a `BailoutError`), `capture(fn)` (runs `fn` and absorbs both `BailoutError` and any thrown legacy `jaiphError` whose message parses as `path:line:col CODE message` — turning the throw into a recoverable entry without re-throwing), `hasErrors()` / `hasFatal()`, `sorted()` (stable order by file, then line, then column), `formatLines()` (one `path:line:col CODE message` per line), and a legacy `throwFirstIfAny()` bridge that throws the first sorted diagnostic via `jaiphError` so existing single-error call sites and per-error tests are unchanged. `src/transpile/validate.ts` exposes a new `collectDiagnostics(graph): Diagnostics` entry that walks the import closure and never throws on user-level errors; the previous `validateReferences(graph)` is now a thin wrapper that calls `collectDiagnostics` and then `throwFirstIfAny()`, preserving the throw-on-first contract for `emitScriptsForModuleFromGraph` / `buildScriptsFromGraph` and for every existing `parse-*.test.ts` / `validate-*.test.ts` fixture that asserts one specific `{ message, line, col, code }`. Inside `validate.ts` every `throw jaiphError(...)` site at user-level (~50 sites across import resolution, channel-route validation, per-rule and per-workflow step walks, prompt schema checks, and `validateTestBlocks`) is migrated to `diag.error(...)`; each top-level unit is wrapped in `diag.capture(...)` (per-import block, per-channel route, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step) so the bailout from one error unwinds only that unit and the next sibling still runs. The four leaf validation helpers (`validate-ref-resolution.ts`, `validate-string.ts`, `validate-prompt-schema.ts`, `shell-jaiph-guard.ts`) still throw via `jaiphError`, but every caller wraps them in `diag.capture(...)`, which converts the thrown error into a recoverable diagnostic and returns. The CLI command `jaiph compile` (`src/cli/commands/compile.ts`) is rewritten to route through `collectDiagnostics`: it accumulates every error from every entry's import closure, sorts them by `(file, line, col)`, and prints the full set — as a single JSON array on stdout under `--json`, or as one `path:line:col CODE message` line per diagnostic on stderr otherwise — exiting **1** on any non-empty diagnostic set. Fatal aborts during graph load or parsing (unterminated triple-quote, unterminated brace block, missing imports during graph build) are reported as a single diagnostic for the affected entry; the command then continues with the next entry. New tests in `src/transpile/diagnostics-collector.test.ts` pin the invariants: a fixture with three independent errors (duplicate import alias, undefined channel, unknown `run` target in one workflow body) asserts `collectDiagnostics(graph)` returns all three in source order (AC1); a source-tree scan asserts `validate.ts` holds **zero** `throw jaiphError(` sites and **≥40** `diag.error(` sites, and that every remaining `throw jaiphError(` under `src/` lives in the documented fatal allowlist — `src/diagnostics.ts` (legacy bridge), `src/parse/core.ts` (parser `fail()`), `src/cli/commands/test.ts` (test-file shape fatal), `src/transpile/module-graph.ts` (loader), `src/transpile/validate-string.ts`, `src/transpile/validate-prompt-schema.ts`, `src/transpile/validate-ref-resolution.ts`, `src/transpile/shell-jaiph-guard.ts` (leaf helpers, each captured) (AC3); and a CLI test runs `jaiph compile --json` against the same fixture and asserts the returned array has all three diagnostics and `status !== 0` (AC4). Existing single-error tests (every `parse-*.test.ts` and `validate-*.test.ts` that pins one specific `{ message, line, col, code }`) still pass because `validateReferences` continues to throw the first sorted diagnostic (AC2); `npm test` and `npm run build` pass (AC5). User-visible contracts on the `jaiph run` / `jaiph test` paths — banner, hooks, run artifacts, exit codes, `__JAIPH_EVENT__` streaming, and golden corpus — are unchanged. Out of scope: changing what counts as an error (this refactor only changes the *how*); LSP integration follows in a separate task. Docs updated in `docs/architecture.md` (new **Diagnostics collector (recoverable errors)** bullet under **Validator**; updated **System overview** to describe the two entry points and the new `jaiph compile` behavior), `docs/cli.md` (new **Multiple-error reporting** paragraph and refined **`--json`** description under **`jaiph compile`**), and `docs/contributing.md` (new **Diagnostics collector shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix B. - **Refactor — Fold the validator's three workflow pre-passes into a single step-tree walk:** `src/transpile/validate.ts` used to descend each workflow's / rule's step tree four times before its main check loop finished — `collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`, and the per-step validator itself — each re-implementing the same recursion over `if` / `for_lines` / `catch` / `recover` with subtly different rules, so "what counts as a binding here" fixes had to land in two or three walkers. The three pre-pass helpers are deleted. One new helper `walkStepTree(filePath, steps, envDecls, params, declLoc, moduleScripts, parseSchemaFieldNames, { withPromptSchemas })` descends the tree once and returns `{ knownVars, promptSchemas, flat }`: it accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings — workflow walks set `withPromptSchemas: true`, rule walks set it `false`), enforces immutable-binding and `script`-collision rules inline through a shared `bindings` map (with a fresh inner map under each `for_lines` body so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding (`recoverBindings: Set | undefined`) attached. The per-workflow and per-rule validator loops now iterate that flat list non-recursively — the `if` / `for_lines` / `catch` / `recover` recursion that used to live inside `validateStep` / `validateRuleStep` is gone. `walkStepTree`'s internal `descend` is the only recursive helper in the file that takes a `WorkflowStepDef[]`. Failure order matches the prior "binding errors first, then per-step errors" behavior because binding checks fire during the descent, before any flat-list iteration starts. Every existing `E_VALIDATE` error message and location is preserved bit-for-bit: the full `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New tests pin the invariants: `src/transpile/validate-single-walk.test.ts` greps `validate.ts` and fails if any of `collectKnownVars`, `collectPromptSchemas`, or `validateImmutableBindings` reappear by name (AC1), and a textual AST scan asserts that at most one recursive helper whose parameter list mentions `WorkflowStepDef[]` exists in the file (AC2). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the visitor-table refactor (Refactor 4) and any change to validation rules. Docs updated in `docs/architecture.md` (new **Single workflow walk** bullet under **Validator**) and `docs/contributing.md` (new **Validator single-walk shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix C. - **Refactor — Collapse the AST around a single `Expr` type, eliminating the three "managed call" encodings:** The same concept "a managed call that yields a value" used to be encoded three different ways: as a statement (`{ type: "run", workflow, args }`), as a const RHS (`{ kind: "run_capture", ref, args }`), and as a `managed:` sidecar on `return` / `log` / `logerr` whose `value` / `message` carried a placeholder string (`"__match__"`, `"run inline_script"`, etc.). Inline scripts added a fourth (`run_inline_script_capture`); `prompt`, `match`, and `ensure` captures repeated the same dual representation. The validator, formatter, emitter, and runtime each had to handle both branches at every site. All three encodings are gone. The semantic AST now has a single `Expr` tagged union — `literal | call | ensure_call | inline_script | prompt | match | shell | bare_ref` — used everywhere a value can appear: `const name = `, `return `, `send channel <- `, the message of `log` / `logerr` / `fail`, and the body of an `exec` step (the new statement-form managed call, where the value is consumed for its side effects plus optional capture). `ConstRhs` and `SendRhsDef` are deleted as separate types. The `managed:` sidecar field is deleted from `WorkflowStepDef`. The placeholder strings `"__match__"`, `"run inline_script"`, and `"__JAIPH_MANAGED__"` no longer appear anywhere under `src/`. `WorkflowStepDef` collapses from 14 variants to **8** (`exec`, `const`, `return`, `send`, `say`, `if`, `for_lines`, `trivia`): `exec` is the new managed-statement form covering the prior `run` / `ensure` / `run_inline_script` / `prompt` / `shell` / standalone `match` cases (the discriminator now lives inside `body.kind`, with `captureName` / `catch` / `recover` as step-level attributes); `say` covers the prior `log` / `logerr` / `fail` cases (`level: "fail"` aborts the workflow with the message, otherwise the message is written to the corresponding stream); `comment` / `blank_line` collapse into a single `trivia` variant (formatter-only, skipped by validator and runtime). The parser builds `Expr` nodes directly: `parseConstRhs` returns `{ value: Expr }`; `parseSendRhs` returns `{ value: Expr }`; `parsePromptStep` returns an `exec` step whose `body` is an `Expr.prompt`; `return run …` / `return ensure …` / `return match …` / `return run \`…\`(…)` build `Expr.call` / `Expr.ensure_call` / `Expr.match` / `Expr.inline_script` directly with no sidecar; `log run \`…\`(…)` and `logerr run \`…\`(…)` build `say` steps whose `message` is an `Expr.inline_script`. Downstream consumers compress accordingly: the validator switches on the 8-variant `WorkflowStepDef.type` and the 8-kind `Expr.kind` with no "literal value vs managed sidecar" fork; the formatter renders each `Expr` through one `emitExpr` helper instead of branching on a sidecar; the runtime has one private `evaluateExpr(scope, expr, …)` dispatcher that `const` / `return` / `send` / `say` / `exec` all delegate to (which runs the managed call for `call` / `ensure_call` / `inline_script`, walks `match` arms, schema-checks `prompt`, and interpolates `literal` via `interpolateWithCaptures`); the script-emit walk in `src/transpile/emit-script.ts` finds inline-script bodies by recursing into each step's `Expr` payload rather than enumerating the four legacy carriers. New tests pin the invariants: `src/types-shape.test.ts` is a compile-time exhaustive `switch` plus runtime tuple assertion that `WorkflowStepDef` has exactly **8** variants and `Expr` has exactly **8** kinds (AC2), a `grep` over every non-test `.ts` file under `src/` that fails if any of the placeholder strings (`"__match__"`, `"run inline_script"`, `"__JAIPH_MANAGED__"`) reappear (AC1), and an export-surface check that fails if `ConstRhs` or `SendRhsDef` are re-exported from `src/types.ts` (AC3). Updated parser tests in `src/parse/parse-return.test.ts`, `src/parse/parse-const-rhs.test.ts`, `src/parse/parse-prompt.test.ts`, `src/parse/parse-send-rhs.test.ts`, `src/parse/parse-steps.test.ts`, `src/parse/parse-inline-script.test.ts`, and `src/parse/parse-bare-call.test.ts` assert the new `Expr` shape directly for `return run …`, `return ensure …`, `return match … { … }`, `return run \`…\`(…)`, `log run \`…\`(…)`, and `const x = prompt …` (AC4). The golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`) passes byte-for-byte against the emitted bash output; `src/format/roundtrip.test.ts` round-trips bit-for-bit on every fixture; `npm run build` passes with zero TypeScript strict-mode errors (AC5 / AC6). Golden AST fixtures under `test-fixtures/golden-ast/expected/` are regenerated to reflect the new step shapes (`exec` wrapping every managed call, `say` replacing `log` / `logerr` / `fail`, `trivia` replacing `comment` / `blank_line`, `Expr` value/message/body payloads). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: surface syntax, the validator's deeper structural rewrite (Refactor 4), and parser internals (Refactors 1 & 2). Docs updated in `docs/architecture.md` (rewrote the **AST / Types** bullet to describe the single `Expr` sum and the 8-variant `WorkflowStepDef`; updated **Validator**, **Formatter**, **Node Workflow Runtime**, and **Trivia / CST layer** bullets to drop the dual-representation language; rewrote the `match_expr` mention in **CLI progress reporting pipeline** to use `Expr.kind === "match"`) and `docs/contributing.md` (new **`Expr` / step-variant shape** row in the test-layer table).

The main per-step validator loop iterates that flat list non-recursively, so `walkStepTree`'s internal `descend` is the **only** recursive helper in the file that takes a `WorkflowStepDef[]`.

It looks the step's `type` up in `VALIDATORS` (the dispatch table), then consults `ctx.scope.allowSteps` (a `Set`) once to decide whether this step is permitted in the current scope. Two scopes exist: `WORKFLOW_SCOPE` (allows every step variant including `send` and `prompt`) and `RULE_SCOPE` (rejects `send` outright; rejects `prompt` and `run async` from inside `exec` bodies). The scope also carries `runRefExpect` (`RUN_TARGET_REF_EXPECT` for workflows, `RUN_IN_RULE_REF_EXPECT` for rules) and `withPromptSchemas` (workflows collect prompt-returning bindings; rules skip schema collection). Adding a new step type requires exactly one row in `VALIDATORS` and, if the rule/workflow split needs to differ, an entry in `Scope.allowSteps` — an `AC4` test in `validate-visitor.test.ts` injects a synthetic step type and asserts it produces exactly one diagnostic with the documented `internal: no validator for step type "…"` message until the row is added. + - **Single managed-call-shape helper.** Every `call` / `ensure_call` site runs the same five checks against the typed `Arg[]` directly — shell-redirection rejection (only `literal` args are scanned), nested-unmanaged-call rejection inside `literal` raws, ref resolution (with the scope's `runRefExpect` for `call`, `RULE_REF_EXPECT` for `ensure_call`), arity (`args.length` vs declared params), and `var`-arg resolution against in-scope bindings via `validateArgVarRefs`. The sequence lives once in `validateCallable(expr, ctx)`; both `run` and `ensure` validators invoke it with a different ref expectation / target kind.

Use | **Call-args AST shape** | `src/parse/arg-ast-shape.test.ts`, `src/parse/arg-grep.test.ts` | Pins the typed-`Arg[]` invariant: no `bareIdentifierArgs` field on any call-bearing AST type (compile-time), no `args.split(",")` or `bareIdentifierArgs` text in production `src/parse/` or `src/transpile/` sources, and no `validateBareIdentifierArgs` helper in the validator | You changed how call arguments flow through the parser, validator, or emitter and need to confirm nothing re-introduces the parallel raw-string representation (see [Architecture — AST / Types](architecture.md#core-components)) | | **`Expr` / step-variant shape** | `src/types-shape.test.ts` | Pins the collapsed-AST invariants from the `Expr` refactor: exactly 8 `WorkflowStepDef` variants and exactly 8 `Expr` kinds (compile-time exhaustive switch + runtime tuple count), no AST placeholder strings (`"__match__"`, `"run inline_script"`, `"__JAIPH_MANAGED__"`) anywhere under `src/`, and `ConstRhs` / `SendRhsDef` no longer exported from `src/types.ts` | You added or renamed a step variant or `Expr` kind, or reshuffled how value positions are encoded; rerun this test to confirm nothing re-introduces the three-way "managed call" encoding (see [Architecture — AST / Types](architecture.md#core-components)) | | **Validator single-walk shape** | `src/transpile/validate-single-walk.test.ts` | Pins the validator's "one descent per workflow / rule" invariant: a name-grep fails if `collectKnownVars`, `collectPromptSchemas`, or `validateImmutableBindings` reappear as separate helpers in `validate.ts`, and a textual AST scan fails if more than one recursive helper walking `WorkflowStepDef[]` lives in that file | You touched `walkStepTree`, added a new pre-pass over workflow steps, or restructured how the validator accumulates `knownVars` / `promptSchemas` / `bindings` — rerun this test to confirm the step tree is still descended exactly once (see [Architecture — Validator](architecture.md#core-components)) | +| **Validator visitor-table shape** | `src/transpile/validate-visitor.test.ts` | Pins the per-step visitor refactor: an LoC test caps `validate.ts` at **≤700 lines** so new per-step logic lands in `validate-step.ts` instead of the outer entry; a `JSON` snapshot over every `validate-*` txtar fixture (stored in `test-fixtures/compiler-txtar/validate-diagnostics-snapshot.json`) pins each diagnostic's `{ code, line, col, message }` bit-for-bit, so any drift in wording or location across the visitor table fails the test; an "unknown step type" test injects a synthetic `WorkflowStepDef.type` and asserts it produces exactly one `internal: no validator for step type "…"` diagnostic in both `WORKFLOW_SCOPE` and `RULE_SCOPE` — proving adding a new step type costs exactly one row in `VALIDATORS` | You touched the `VALIDATORS` table, changed `validateStep` / `validateExpr` / `validateCallable` / `Scope`, added or renamed a per-step validator in `validate-step.ts`, or changed any `E_VALIDATE` message wording or source location — refresh the snapshot with `UPDATE_SNAPSHOTS=1` only after confirming the message change is intentional (see [Architecture — Validator](architecture.md#core-components)) | | **Diagnostics collector shape** | `src/transpile/diagnostics-collector.test.ts` | Pins the migration from fail-fast `throw jaiphError(...)` to the `Diagnostics` collector: a fixture with three independent errors (duplicate import alias, undefined channel, unknown `run` target) asserts that `collectDiagnostics(graph)` returns **all three** in source order; a source grep asserts `validate.ts` holds **zero** `throw jaiphError(` sites and many `diag.error(` sites; an allowlist scan over every non-test `*.ts` under `src/` rejects new `throw jaiphError(` sites outside the documented fatal subset (parser `fail()`, loader, test-file shape check, legacy bridge, four leaf helpers wrapped in `diag.capture(...)`); a CLI test asserts `jaiph compile --json` returns the full diagnostic array and exits non-zero | You added a new `throw jaiphError(...)` site, migrated more checks to the collector, changed the fatal/recoverable boundary, or changed `jaiph compile`'s exit-code or output shape (see [Architecture — Validator](architecture.md#core-components) and [CLI](cli.md)) | | **Compiler tests (txtar)** | `test-fixtures/compiler-txtar/*.txt` | Parse and validate outcomes — success, parse errors, validation errors — using language-agnostic txtar fixtures (hundreds of `===` cases across the four `*.txt` files) | You want a portable test case that can be reused by alternative compiler implementations; the test is a `.jh` input paired with an expected outcome | | **Golden AST tests** | `test-fixtures/golden-ast/fixtures/*.jh` + `test-fixtures/golden-ast/expected/*.json` | Parse tree shape for successful parses — serialized to deterministic JSON with locations stripped (9 fixtures: e.g. imports, brace-if, log, match and match-multiline, params, prompt-capture, run-ensure, script-defs) | You changed the parser and need to verify the AST structure hasn't drifted;

import `tripleQuotedRawForRuntime` from `src/runtime/orchestration-text.ts` to compute "what the runtime will see" for triple-quoted match-arm bodies — a one-way compile-time dependency on runtime semantics. Move the helper into the parser layer as `canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts`; both the validator and the runtime now import it from `src/parse/`, and the `src/runtime/orchestration-text.ts` wrapper is deleted. New tests pin the invariants: `no-runtime-imports.test.ts` greps every non-test `*.ts` under `src/transpile/` and fails on any `from "…/runtime/…"` import, and `canonicalize-triple-quoted.test.ts` walks every triple-quoted match-arm body in `test-fixtures/` and `examples/` and asserts bit-for-bit parity against an inlined legacy baseline. --- CHANGELOG.md | 1 + QUEUE.md | 26 ----- docs/architecture.md | 3 +- docs/contributing.md | 1 + src/parse/canonicalize-triple-quoted.test.ts | 105 +++++++++++++++++++ src/parse/triple-quote.ts | 17 +++ src/runtime/kernel/node-workflow-runtime.ts | 4 +- src/runtime/orchestration-text.ts | 18 ---- src/transpile/no-runtime-imports.test.ts | 38 +++++++ src/transpile/validate-step.ts | 4 +- 10 files changed, 168 insertions(+), 49 deletions(-) create mode 100644 src/parse/canonicalize-triple-quoted.test.ts delete mode 100644 src/runtime/orchestration-text.ts create mode 100644 src/transpile/no-runtime-imports.test.ts diff --git a/CHANGELOG.md b/CHANGELOG.md index 0d96e98c..ae98f452 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -1,5 +1,6 @@ # Unreleased +- **Refactor — Decouple the validator from runtime semantics:** `src/transpile/validate.ts` (now `validate-step.ts`) used to `import { tripleQuotedRawForRuntime } from "../runtime/orchestration-text"` so it could compute "what the runtime will see" when checking the content of a triple-quoted `match`-arm body. That was a one-way dependency from compile-time on runtime semantics — a layering inversion that would have kept biting as the runtime grew more such helpers. The canonicalization helper moves into the parser layer as `canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts` (same algorithm: validate the outer `"…"` shape, unescape DSL-quoted inner with `\"` → `"` and `\\` → `\`, then re-wrap via `tripleQuoteBodyToRaw(dedentCommonLeadingWhitespace(inner))`). Both the validator (`validate-step.ts`'s `validateMatchExpr`) and the runtime (`src/runtime/kernel/node-workflow-runtime.ts`'s match-arm dispatch in `runMatchExpr`) now import that helper from `src/parse/`; the wrapper file `src/runtime/orchestration-text.ts` is deleted. New tests pin the invariants: `src/transpile/no-runtime-imports.test.ts` (AC1) greps every non-test `*.ts` under `src/transpile/` and fails if any `from "…/runtime/…"` import reappears, so compile-time code can no longer reach into runtime semantics; `src/parse/canonicalize-triple-quoted.test.ts` (AC2) parses every `.jh` under `test-fixtures/` and `examples/`, collects every triple-quoted `match`-arm body across workflow / rule step trees, and asserts `canonicalizeTripleQuotedString(body) === legacyTripleQuotedRawForRuntime(body)` bit-for-bit (the legacy implementation is inlined in the test as the parity baseline). Existing `validate-string.test.ts` cases and the golden corpus pass unchanged (AC3); `npm run build` passes with zero TypeScript strict-mode errors (AC4). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: rethinking what the canonical form *is* — this refactor only relocates the helper. Docs updated in `docs/architecture.md` (new **No compile-time → runtime imports** bullet under **Validator**; extended **Parser** bullet to document `canonicalizeTripleQuotedString` alongside `parseTripleQuoteBlock`) and `docs/contributing.md` (new **Compile-time / runtime layering** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix E. - **Refactor — Replace the 1,441-line validator switch with a per-step visitor table indexed by scope:** `src/transpile/validate.ts` used to be one ~1,441-LoC function with two near-identical inner walkers (`validateRuleStep` ~250 lines, `validateStep` ~350 lines): every step type's validation was written twice with subtle differences, and the five-check call-shape sequence (`validateNoShellRedirection` → `validateNestedManagedCallArgs` → `validateRef` → `validateArity` → `validateBareIdentifierArgs`) was repeated by hand at 6+ sites per side — at least 12 places to keep in sync. Both inner walkers and every duplicated check site are gone. The validator now spans two files. `validate.ts` (~430 LoC) keeps the **outer** layer: import / channel-route / test-block checks and `walkStepTree` (the single descent that builds `{ knownVars, promptSchemas, flat }`). `validate-step.ts` (~1,025 LoC) holds the **per-step** visitor: a single `validateStep(step, ctx)` entry, a `VALIDATORS: Record` table with one row per step variant (`trivia`, `const`, `return`, `send`, `say`, `exec`, `if`, `for_lines`), one `validateExpr(expr, …)` dispatcher over the 8 `Expr.kind` values, and one `validateCallable(expr, ctx)` helper that runs the five managed-call-shape checks once for both `call` (`run`) and `ensure_call` (`ensure`) — parameterized by the scope's `runRefExpect` and the target kind. Rule-vs-workflow differences are captured in a `Scope` value (`WORKFLOW_SCOPE` / `RULE_SCOPE`) with three fields: `allowSteps: Set` (single set-lookup gate at the top of `validateStep` — rules reject `send` outright; rules also reject `prompt` and `run async` from inside `exec` bodies), `runRefExpect: RefExpectMessages` (workflow vs rule semantics for `run ref(…)`), and `withPromptSchemas: boolean` (workflows collect prompt-returning bindings, rules skip schema collection). `ValidatorCtx` threads the scope plus the precomputed `knownVars`, `promptSchemas`, and `recoverBindings` into every visitor — none of which are re-derived per step. Every existing `E_VALIDATE` error message and source location is preserved bit-for-bit: the entire `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New acceptance tests in `src/transpile/validate-visitor.test.ts` pin the invariants: an LoC test caps `validate.ts` at **≤700 lines** so new per-step logic lands in `validate-step.ts` (AC1); a JSON snapshot over every `validate-*` txtar fixture (`test-fixtures/compiler-txtar/validate-errors.txt` + `validate-errors-multi-module.txt`) stored in `test-fixtures/compiler-txtar/validate-diagnostics-snapshot.json` asserts each diagnostic's `{ code, line, col, message }` against `collectDiagnostics(graph)` bit-for-bit (AC3 — refreshable via `UPDATE_SNAPSHOTS=1` only after confirming the message change is intentional); and an "unknown step type" test casts a synthetic step variant into `WorkflowStepDef`, runs `validateStep` in both `WORKFLOW_SCOPE` and `RULE_SCOPE`, and asserts each call produces exactly one diagnostic with the documented `internal: no validator for step type "…"` message (AC4 — proving that adding a new step type costs exactly one row in `VALIDATORS`). The existing `src/transpile/validate-single-walk.test.ts` still passes — `walkStepTree`'s internal `descend` remains the only recursive `WorkflowStepDef[]` walker in `validate.ts` (AC2). The `diagnostics-collector.test.ts` "fatal allowlist" scan now sums `throw jaiphError(` counts across `validate.ts` + `validate-step.ts` (both files are zero) and `diag.error(` counts likewise (≥40). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: changes to validation rules (the *what* — this refactor only changes the *how*), parser changes, AST changes. Docs updated in `docs/architecture.md` (rewrote the **Validator** section to describe the two-file split, `VALIDATORS` table, `Scope` value, and the single `validateCallable` helper), `docs/contributing.md` (new **Validator visitor-table shape** row in the test-layer table), and `docs/grammar.md` (refreshed two stale `validateRuleStep` references to point at the new visitor / `RULE_SCOPE`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 4. - **Refactor — Replace fail-fast errors with a `Diagnostics` collector that aggregates every recoverable error per compile:** Today `fail()` (in `src/parse/core.ts`) and `jaiphError()` (in `src/errors.ts`) both throw on the first error, so a user fixed one error, recompiled, hit the next, recompiled, and so on. The validator also pre-ordered some checks defensively because it knew it would only get to surface one error per run. That model is replaced. A new `Diagnostics` class lives in `src/diagnostics.ts` and exposes `add(d)`, `error(file, line, col, code, message)` (records the diagnostic and short-circuits the current unit through a `BailoutError`), `capture(fn)` (runs `fn` and absorbs both `BailoutError` and any thrown legacy `jaiphError` whose message parses as `path:line:col CODE message` — turning the throw into a recoverable entry without re-throwing), `hasErrors()` / `hasFatal()`, `sorted()` (stable order by file, then line, then column), `formatLines()` (one `path:line:col CODE message` per line), and a legacy `throwFirstIfAny()` bridge that throws the first sorted diagnostic via `jaiphError` so existing single-error call sites and per-error tests are unchanged. `src/transpile/validate.ts` exposes a new `collectDiagnostics(graph): Diagnostics` entry that walks the import closure and never throws on user-level errors; the previous `validateReferences(graph)` is now a thin wrapper that calls `collectDiagnostics` and then `throwFirstIfAny()`, preserving the throw-on-first contract for `emitScriptsForModuleFromGraph` / `buildScriptsFromGraph` and for every existing `parse-*.test.ts` / `validate-*.test.ts` fixture that asserts one specific `{ message, line, col, code }`. Inside `validate.ts` every `throw jaiphError(...)` site at user-level (~50 sites across import resolution, channel-route validation, per-rule and per-workflow step walks, prompt schema checks, and `validateTestBlocks`) is migrated to `diag.error(...)`; each top-level unit is wrapped in `diag.capture(...)` (per-import block, per-channel route, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step) so the bailout from one error unwinds only that unit and the next sibling still runs. The four leaf validation helpers (`validate-ref-resolution.ts`, `validate-string.ts`, `validate-prompt-schema.ts`, `shell-jaiph-guard.ts`) still throw via `jaiphError`, but every caller wraps them in `diag.capture(...)`, which converts the thrown error into a recoverable diagnostic and returns. The CLI command `jaiph compile` (`src/cli/commands/compile.ts`) is rewritten to route through `collectDiagnostics`: it accumulates every error from every entry's import closure, sorts them by `(file, line, col)`, and prints the full set — as a single JSON array on stdout under `--json`, or as one `path:line:col CODE message` line per diagnostic on stderr otherwise — exiting **1** on any non-empty diagnostic set. Fatal aborts during graph load or parsing (unterminated triple-quote, unterminated brace block, missing imports during graph build) are reported as a single diagnostic for the affected entry; the command then continues with the next entry. New tests in `src/transpile/diagnostics-collector.test.ts` pin the invariants: a fixture with three independent errors (duplicate import alias, undefined channel, unknown `run` target in one workflow body) asserts `collectDiagnostics(graph)` returns all three in source order (AC1); a source-tree scan asserts `validate.ts` holds **zero** `throw jaiphError(` sites and **≥40** `diag.error(` sites, and that every remaining `throw jaiphError(` under `src/` lives in the documented fatal allowlist — `src/diagnostics.ts` (legacy bridge), `src/parse/core.ts` (parser `fail()`), `src/cli/commands/test.ts` (test-file shape fatal), `src/transpile/module-graph.ts` (loader), `src/transpile/validate-string.ts`, `src/transpile/validate-prompt-schema.ts`, `src/transpile/validate-ref-resolution.ts`, `src/transpile/shell-jaiph-guard.ts` (leaf helpers, each captured) (AC3); and a CLI test runs `jaiph compile --json` against the same fixture and asserts the returned array has all three diagnostics and `status !== 0` (AC4). Existing single-error tests (every `parse-*.test.ts` and `validate-*.test.ts` that pins one specific `{ message, line, col, code }`) still pass because `validateReferences` continues to throw the first sorted diagnostic (AC2); `npm test` and `npm run build` pass (AC5). User-visible contracts on the `jaiph run` / `jaiph test` paths — banner, hooks, run artifacts, exit codes, `__JAIPH_EVENT__` streaming, and golden corpus — are unchanged. Out of scope: changing what counts as an error (this refactor only changes the *how*); LSP integration follows in a separate task. Docs updated in `docs/architecture.md` (new **Diagnostics collector (recoverable errors)** bullet under **Validator**; updated **System overview** to describe the two entry points and the new `jaiph compile` behavior), `docs/cli.md` (new **Multiple-error reporting** paragraph and refined **`--json`** description under **`jaiph compile`**), and `docs/contributing.md` (new **Diagnostics collector shape** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix B. - **Refactor — Fold the validator's three workflow pre-passes into a single step-tree walk:** `src/transpile/validate.ts` used to descend each workflow's / rule's step tree four times before its main check loop finished — `collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`, and the per-step validator itself — each re-implementing the same recursion over `if` / `for_lines` / `catch` / `recover` with subtly different rules, so "what counts as a binding here" fixes had to land in two or three walkers. The three pre-pass helpers are deleted. One new helper `walkStepTree(filePath, steps, envDecls, params, declLoc, moduleScripts, parseSchemaFieldNames, { withPromptSchemas })` descends the tree once and returns `{ knownVars, promptSchemas, flat }`: it accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings — workflow walks set `withPromptSchemas: true`, rule walks set it `false`), enforces immutable-binding and `script`-collision rules inline through a shared `bindings` map (with a fresh inner map under each `for_lines` body so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding (`recoverBindings: Set | undefined`) attached. The per-workflow and per-rule validator loops now iterate that flat list non-recursively — the `if` / `for_lines` / `catch` / `recover` recursion that used to live inside `validateStep` / `validateRuleStep` is gone. `walkStepTree`'s internal `descend` is the only recursive helper in the file that takes a `WorkflowStepDef[]`. Failure order matches the prior "binding errors first, then per-step errors" behavior because binding checks fire during the descent, before any flat-list iteration starts. Every existing `E_VALIDATE` error message and location is preserved bit-for-bit: the full `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New tests pin the invariants: `src/transpile/validate-single-walk.test.ts` greps `validate.ts` and fails if any of `collectKnownVars`, `collectPromptSchemas`, or `validateImmutableBindings` reappear by name (AC1), and a textual AST scan asserts that at most one recursive helper whose parameter list mentions `WorkflowStepDef[]` exists in the file (AC2). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged. Out of scope: the visitor-table refactor (Refactor 4) and any change to validation rules. Docs updated in `docs/architecture.md` (new **Single workflow walk** bullet under **Validator**) and `docs/contributing.md` (new **Validator single-walk shape** row in the test-layer table).

Every recoverable check appends to a `Diagnostics` collector (`src/diagnostics.ts`) via `diag.error(file, line, col, code, msg)`, which records a `JaiphDiagnostic` and short-circuits the current validation unit through a `BailoutError`. Each top-level unit (per-import block, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step, per-channel route) is wrapped in `diag.capture(fn)`, which absorbs the bailout (and any thrown `jaiphError` from leaf helpers like `validate-ref-resolution.ts` / `validate-string.ts` / `validate-prompt-schema.ts` / `shell-jaiph-guard.ts`) so the next sibling unit still runs. `collectDiagnostics(graph)` walks every module and returns the populated collector; the legacy `validateReferences(graph)` is now a thin wrapper that throws the first sorted diagnostic via `jaiphError` so existing per-error tests and the `emitScriptsForModuleFromGraph` path keep working unchanged. `Diagnostics.sorted()` returns errors ordered by `(file, line, col)`; `formatLines()` renders the standard `path:line:col CODE message` shape. A grep test (`src/transpile/diagnostics-collector.test.ts`) pins the migration: `validate.ts` + `validate-step.ts` hold **zero** `throw jaiphError(` sites, and the remaining `throw jaiphError(` call sites under `src/` are confined to a documented allowlist — fatal aborts in the parser (`src/parse/core.ts`), the loader (`src/transpile/module-graph.ts`), and the test-file shape check (`src/cli/commands/test.ts`); the legacy bridge in `src/diagnostics.ts`; and the four leaf validation helpers above, each of which has every caller wrapped in `diag.capture(...)`. - The validator drives off `WorkflowStepDef.type` (8 variants) and `Expr.kind` (8 variants). For every value-bearing step (`const` / `return` / `send` / `say`) and for the body of every `exec` step, a single `validateExpr(expr, ...)` dispatcher handles the value: it routes `call` / `ensure_call` / `inline_script` to call-site validation (`validateCallable`), walks `match` arms, schema-checks `prompt`, and runs the substitution scanner on `literal` raws. There is no dual code path for "managed sidecar vs literal value" — that branch is gone. + - **No compile-time → runtime imports.** Nothing under `src/transpile/` may `import … from "…/runtime/…"`. Compile-time code must not depend on runtime semantics: when the validator needs the same canonical form the runtime will see (the dedented, escape-decoded view of a triple-quoted match-arm body), both sides import a parser-side helper (`canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts`) rather than reaching across the layer. A grep test (`src/transpile/no-runtime-imports.test.ts`) scans every non-test `*.ts` under `src/transpile/` and fails if any `from "…/runtime/…"` import appears; a separate corpus test (`src/parse/canonicalize-triple-quoted.test.ts`) parses every `.jh` under `test-fixtures/` and `examples/`, collects every triple-quoted match-arm body, and asserts `canonicalizeTripleQuotedString` matches the pre-move `tripleQuotedRawForRuntime` output bit-for-bit. - **Single workflow walk.** Each workflow / rule has its step tree descended exactly once by `walkStepTree` (in `validate.ts`), which simultaneously accumulates `knownVars` (env decls + params + every nested `const` / capture / `for_lines` iterator), `promptSchemas` (top-level prompt-returning bindings, gated by `options.withPromptSchemas` so rules skip schema collection), enforces immutable-binding / `script`-collision rules inline (mutating a shared `bindings` map and threading a fresh inner map under each `for_lines` so loop iterators only shadow inside the body), and emits a flat `FlatStepEntry[]` of every step in tree order with the enclosing `catch` / `recover` failure binding attached. The main per-step validator loop iterates that flat list non-recursively and calls `validateStep` once per entry, so `walkStepTree`'s internal `descend` is the **only** recursive helper in `validate.ts` that takes a `WorkflowStepDef[]`. A pair of grep / AST tests (`src/transpile/validate-single-walk.test.ts`) pins both invariants: the prior helpers (`collectKnownVars`, `collectPromptSchemas`, `validateImmutableBindings`) cannot reappear by name, and at most one recursive `WorkflowStepDef[]` walker may live in `validate.ts`. - **Transpiler (`src/transpiler.ts`, `src/transpile/*`)** diff --git a/docs/contributing.md b/docs/contributing.md index 0bac96df..cb3ee5d1 100644 --- a/docs/contributing.md +++ b/docs/contributing.md @@ -107,6 +107,7 @@ Jaiph uses several test layers.

All four functions and every helper that existed only to serve them are deleted from `src/parse/steps.ts`. The file drops from **757 → ~140 lines**. The new shape: one entry point `parseAttachedBlock(filePath, lines, idx, innerNo, innerRaw, keyword: "catch" | "recover", textAfterKeyword, trivia)` in `src/parse/steps.ts` parses the bindings (`()` — exactly one identifier, with the same too-many / too-few / non-identifier errors as before) and dispatches on the body shape: a `{` at end of host line walks the existing brace-block scanner and delegates each body statement to `parseBraceBlockBody`, an inline `{ stmt[; stmt]* }` splits on `;` via the shared `splitStatementsOnSemicolons` and dispatches each fragment, and a bare single statement is parsed in-place. In all three cases the body statements run through the **same** `parseBlockStatement` (`src/parse/workflow-brace.ts`) that handles top-level statements — there is no mini parser for catch/recover bodies anymore. The host side moves to one helper `parseRunOrEnsure(filePath, lines, idx, …, host: "run" | "ensure", hostBody, isAsync, captureName, trivia)` in `src/parse/workflow-brace.ts`, called from `parseBlockStatement`'s three call sites (`ensure ref(...)`, `run ref(...)`, `run async ref(...)`). It scans `hostBody` once for a trailing ` recover` (run-only) then ` catch ` segment, parses the host call before the keyword, and delegates the attached clause to `parseAttachedBlock`. "Is this statement allowed inside a catch/recover body?" is now a validator concern — `WORKFLOW_SCOPE` and `RULE_SCOPE` in `validate-step.ts` already gate which step types are accepted in each scope, so rules still reject unstructured shell inside `catch` / `recover` bodies; workflows still accept it. New tests in `src/parse/parse-attached-block.test.ts` pin the invariants: AC1 — an LoC test caps `src/parse/steps.ts` at **≤200 lines** and a grep test fails if any function named `parse(Run)?(Catch|Recover|EnsureStep)` reappears; AC2 — a `for line in items { log "$line" }` statement (a `parseBlockStatement`-only form historically) is parsed as a `for_lines` step at the top level, inside `ensure check() catch (e) { … }`, and inside `run target() recover(e) { … }` — proving `parseBlockStatement` is the single entry point for any statement inside a catch / recover body and there is no separate mini parser; AC3 — a 10-case error-snapshot battery asserts every existing parse error message and column (bindings missing, too many bindings, empty inline / multiline block, unterminated multiline block, missing-paren for both `catch` and `recover` on both `run` and `ensure` hosts) is preserved bit-for-bit. The full parser / validator / emitter golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, `parse-steps.test.ts`, `parse-bare-call.test.ts`, `parse-run-async.test.ts`, and the txtar / golden-AST fixtures) passes byte-for-byte (AC4). User-visible contracts — surface syntax for `catch` / `recover`, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Out of scope: the wider tokenizer rewrite (Refactor 1, deferred); validator changes beyond the per-keyword scope rules that already exist. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Unified `run` / `ensure` host parsing** paragraph), `docs/contributing.md` (new **Attached-block parser shape** row in the test-layer table), and `docs/grammar.md` (replaced the stale `parseCatchStatement` reference in the EBNF aside with a note that `parseAttachedBlock` delegates to `parseBlockStatement`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 2. - **Refactor — Decouple the validator from runtime semantics:** `src/transpile/validate.ts` (now `validate-step.ts`) used to `import { tripleQuotedRawForRuntime } from "../runtime/orchestration-text"` so it could compute "what the runtime will see" when checking the content of a triple-quoted `match`-arm body. That was a one-way dependency from compile-time on runtime semantics — a layering inversion that would have kept biting as the runtime grew more such helpers. The canonicalization helper moves into the parser layer as `canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts` (same algorithm: validate the outer `"…"` shape, unescape DSL-quoted inner with `\"` → `"` and `\\` → `\`, then re-wrap via `tripleQuoteBodyToRaw(dedentCommonLeadingWhitespace(inner))`). Both the validator (`validate-step.ts`'s `validateMatchExpr`) and the runtime (`src/runtime/kernel/node-workflow-runtime.ts`'s match-arm dispatch in `runMatchExpr`) now import that helper from `src/parse/`; the wrapper file `src/runtime/orchestration-text.ts` is deleted. New tests pin the invariants: `src/transpile/no-runtime-imports.test.ts` (AC1) greps every non-test `*.ts` under `src/transpile/` and fails if any `from "…/runtime/…"` import reappears, so compile-time code can no longer reach into runtime semantics; `src/parse/canonicalize-triple-quoted.test.ts` (AC2) parses every `.jh` under `test-fixtures/` and `examples/`, collects every triple-quoted `match`-arm body across workflow / rule step trees, and asserts `canonicalizeTripleQuotedString(body) === legacyTripleQuotedRawForRuntime(body)` bit-for-bit (the legacy implementation is inlined in the test as the parity baseline). Existing `validate-string.test.ts` cases and the golden corpus pass unchanged (AC3); `npm run build` passes with zero TypeScript strict-mode errors (AC4). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: rethinking what the canonical form *is* — this refactor only relocates the helper. Docs updated in `docs/architecture.md` (new **No compile-time → runtime imports** bullet under **Validator**; extended **Parser** bullet to document `canonicalizeTripleQuotedString` alongside `parseTripleQuoteBlock`) and `docs/contributing.md` (new **Compile-time / runtime layering** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix E. - **Refactor — Replace the 1,441-line validator switch with a per-step visitor table indexed by scope:** `src/transpile/validate.ts` used to be one ~1,441-LoC function with two near-identical inner walkers (`validateRuleStep` ~250 lines, `validateStep` ~350 lines): every step type's validation was written twice with subtle differences, and the five-check call-shape sequence (`validateNoShellRedirection` → `validateNestedManagedCallArgs` → `validateRef` → `validateArity` → `validateBareIdentifierArgs`) was repeated by hand at 6+ sites per side — at least 12 places to keep in sync. Both inner walkers and every duplicated check site are gone. The validator now spans two files. `validate.ts` (~430 LoC) keeps the **outer** layer: import / channel-route / test-block checks and `walkStepTree` (the single descent that builds `{ knownVars, promptSchemas, flat }`). `validate-step.ts` (~1,025 LoC) holds the **per-step** visitor: a single `validateStep(step, ctx)` entry, a `VALIDATORS: Record` table with one row per step variant (`trivia`, `const`, `return`, `send`, `say`, `exec`, `if`, `for_lines`), one `validateExpr(expr, …)` dispatcher over the 8 `Expr.kind` values, and one `validateCallable(expr, ctx)` helper that runs the five managed-call-shape checks once for both `call` (`run`) and `ensure_call` (`ensure`) — parameterized by the scope's `runRefExpect` and the target kind. Rule-vs-workflow differences are captured in a `Scope` value (`WORKFLOW_SCOPE` / `RULE_SCOPE`) with three fields: `allowSteps: Set` (single set-lookup gate at the top of `validateStep` — rules reject `send` outright; rules also reject `prompt` and `run async` from inside `exec` bodies), `runRefExpect: RefExpectMessages` (workflow vs rule semantics for `run ref(…)`), and `withPromptSchemas: boolean` (workflows collect prompt-returning bindings, rules skip schema collection). `ValidatorCtx` threads the scope plus the precomputed `knownVars`, `promptSchemas`, and `recoverBindings` into every visitor — none of which are re-derived per step. Every existing `E_VALIDATE` error message and source location is preserved bit-for-bit: the entire `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New acceptance tests in `src/transpile/validate-visitor.test.ts` pin the invariants: an LoC test caps `validate.ts` at **≤700 lines** so new per-step logic lands in `validate-step.ts` (AC1); a JSON snapshot over every `validate-*` txtar fixture (`test-fixtures/compiler-txtar/validate-errors.txt` + `validate-errors-multi-module.txt`) stored in `test-fixtures/compiler-txtar/validate-diagnostics-snapshot.json` asserts each diagnostic's `{ code, line, col, message }` against `collectDiagnostics(graph)` bit-for-bit (AC3 — refreshable via `UPDATE_SNAPSHOTS=1` only after confirming the message change is intentional); and an "unknown step type" test casts a synthetic step variant into `WorkflowStepDef`, runs `validateStep` in both `WORKFLOW_SCOPE` and `RULE_SCOPE`, and asserts each call produces exactly one diagnostic with the documented `internal: no validator for step type "…"` message (AC4 — proving that adding a new step type costs exactly one row in `VALIDATORS`). The existing `src/transpile/validate-single-walk.test.ts` still passes — `walkStepTree`'s internal `descend` remains the only recursive `WorkflowStepDef[]` walker in `validate.ts` (AC2). The `diagnostics-collector.test.ts` "fatal allowlist" scan now sums `throw jaiphError(` counts across `validate.ts` + `validate-step.ts` (both files are zero) and `diag.error(` counts likewise (≥40). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: changes to validation rules (the *what* — this refactor only changes the *how*), parser changes, AST changes. Docs updated in `docs/architecture.md` (rewrote the **Validator** section to describe the two-file split, `VALIDATORS` table, `Scope` value, and the single `validateCallable` helper), `docs/contributing.md` (new **Validator visitor-table shape** row in the test-layer table), and `docs/grammar.md` (refreshed two stale `validateRuleStep` references to point at the new visitor / `RULE_SCOPE`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 4. - **Refactor — Replace fail-fast errors with a `Diagnostics` collector that aggregates every recoverable error per compile:** Today `fail()` (in `src/parse/core.ts`) and `jaiphError()` (in `src/errors.ts`) both throw on the first error, so a user fixed one error, recompiled, hit the next, recompiled, and so on. The validator also pre-ordered some checks defensively because it knew it would only get to surface one error per run. That model is replaced. A new `Diagnostics` class lives in `src/diagnostics.ts` and exposes `add(d)`, `error(file, line, col, code, message)` (records the diagnostic and short-circuits the current unit through a `BailoutError`), `capture(fn)` (runs `fn` and absorbs both `BailoutError` and any thrown legacy `jaiphError` whose message parses as `path:line:col CODE message` — turning the throw into a recoverable entry without re-throwing), `hasErrors()` / `hasFatal()`, `sorted()` (stable order by file, then line, then column), `formatLines()` (one `path:line:col CODE message` per line), and a legacy `throwFirstIfAny()` bridge that throws the first sorted diagnostic via `jaiphError` so existing single-error call sites and per-error tests are unchanged. `src/transpile/validate.ts` exposes a new `collectDiagnostics(graph): Diagnostics` entry that walks the import closure and never throws on user-level errors; the previous `validateReferences(graph)` is now a thin wrapper that calls `collectDiagnostics` and then `throwFirstIfAny()`, preserving the throw-on-first contract for `emitScriptsForModuleFromGraph` / `buildScriptsFromGraph` and for every existing `parse-*.test.ts` / `validate-*.test.ts` fixture that asserts one specific `{ message, line, col, code }`. Inside `validate.ts` every `throw jaiphError(...)` site at user-level (~50 sites across import resolution, channel-route validation, per-rule and per-workflow step walks, prompt schema checks, and `validateTestBlocks`) is migrated to `diag.error(...)`; each top-level unit is wrapped in `diag.capture(...)` (per-import block, per-channel route, per-rule walk, per-rule step, per-workflow walk, per-workflow step, per-test-block step) so the bailout from one error unwinds only that unit and the next sibling still runs. The four leaf validation helpers (`validate-ref-resolution.ts`, `validate-string.ts`, `validate-prompt-schema.ts`, `shell-jaiph-guard.ts`) still throw via `jaiphError`, but every caller wraps them in `diag.capture(...)`, which converts the thrown error into a recoverable diagnostic and returns. The CLI command `jaiph compile` (`src/cli/commands/compile.ts`) is rewritten to route through `collectDiagnostics`: it accumulates every error from every entry's import closure, sorts them by `(file, line, col)`, and prints the full set — as a single JSON array on stdout under `--json`, or as one `path:line:col CODE message` line per diagnostic on stderr otherwise — exiting **1** on any non-empty diagnostic set. Fatal aborts during graph load or parsing (unterminated triple-quote, unterminated brace block, missing imports during graph build) are reported as a single diagnostic for the affected entry; the command then continues with the next entry. New tests in `src/transpile/diagnostics-collector.test.ts` pin the invariants: a fixture with three independent errors (duplicate import alias, undefined channel, unknown `run` target in one workflow body) asserts `collectDiagnostics(graph)` returns all three in source order (AC1); a source-tree scan asserts `validate.ts` holds **zero** `throw jaiphError(` sites and **≥40** `diag.error(` sites, and that every remaining `throw jaiphError(` under `src/` lives in the documented fatal allowlist — `src/diagnostics.ts` (legacy bridge), `src/parse/core.ts` (parser `fail()`), `src/cli/commands/test.ts` (test-file shape fatal), `src/transpile/module-graph.ts` (loader), `src/transpile/validate-string.ts`, `src/transpile/validate-prompt-schema.ts`, `src/transpile/validate-ref-resolution.ts`, `src/transpile/shell-jaiph-guard.ts` (leaf helpers, each captured) (AC3); and a CLI test runs `jaiph compile --json` against the same fixture and asserts the returned array has all three diagnostics and `status !== 0` (AC4). Existing single-error tests (every `parse-*.test.ts` and `validate-*.test.ts` that pins one specific `{ message, line, col, code }`) still pass because `validateReferences` continues to throw the first sorted diagnostic (AC2); `npm test` and `npm run build` pass (AC5). User-visible contracts on the `jaiph run` / `jaiph test` paths — banner, hooks, run artifacts, exit codes, `__JAIPH_EVENT__` streaming, and golden corpus — are unchanged. Out of scope: changing what counts as an error (this refactor only changes the *how*); LSP integration follows in a separate task. Docs updated in `docs/architecture.md` (new **Diagnostics collector (recoverable errors)** bullet under **Validator**; updated **System overview** to describe the two entry points and the new `jaiph compile` behavior), `docs/cli.md` (new **Multiple-error reporting** paragraph and refined **`--json`** description under **`jaiph compile`**), and `docs/contributing.md` (new **Diagnostics collector shape** row in the test-layer table).

The cascade is replaced by a STATEMENT: Record table keyed by the leading keyword: the dispatcher tokenizes the first identifier on the trimmed line, looks it up, and invokes the matching handler — which returns a result, returns null to fall through, or calls fail(...). The shared per-line context is now a BlockCtx record threaded into every handler. Assignment-shape guards run in applyAssignmentGuards before the lookup. Surface syntax and every existing parse-error message / line / col are preserved. New tests pin the invariants: an error snapshot test compares { file, line, col, code, message } for every fixture in parse-errors.txt against parse-errors-snapshot.json, and a synthetic-keyword test patches STATEMENT at runtime to prove adding a top-level keyword is a two-place change (STATEMENT row + JAIPH_KEYWORDS entry). The wider tokenizer rewrite remains future work.

The cascade is replaced by a `STATEMENT: Record` table keyed by the leading keyword: the dispatcher tokenizes the first identifier on the trimmed line, looks it up in the table, and invokes the matching handler — which returns a `{ step, nextIdx }` result, returns `null` to fall through, or calls `fail(...)` to abort. The current rows are `if`, `for`, `const`, `fail`, `wait`, `ensure`, `run`, `prompt`, `log`, `logerr`, `return`, and `match`; each handler (`tryParseIf`, `tryParseFor`, `tryParseConst`, `tryParseFail`, `tryParseWait`, `tryParseEnsure`, `tryParseRun`, `tryParsePrompt`, `tryParseLog`, `tryParseLogerr`, `tryParseReturn`, `tryParseStandaloneMatch`) carries the same regex / `startsWith` checks that used to live inline in the cascade — body shapes are unchanged. After dispatch, two non-keyword fallbacks fire in order: `trySend` (matches `channel <- rhs` via `matchSendOperator`) and `shellFallthrough` (everything else becomes a shell `exec` step). Assignment-shape error guards (`name = prompt …`, `name = run …` without `const`) live in a separate `applyAssignmentGuards(c)` helper that runs before the table lookup and either calls `fail(...)` or returns; the `forRule` rejection of `prompt …` inside rules also moves here. The shared per-line context (`filePath`, `lines`, `idx`, `innerRaw`, `inner`, `innerNo`, `trivia`, `forRule`, `opts`) is now a `BlockCtx` record threaded into every handler, so handlers take one argument instead of nine. Surface syntax is unchanged, every existing parse-error message / line / col is preserved, and the full golden corpus passes byte-for-byte. New tests pin the invariants: `src/parse/parse-error-snapshot.test.ts` walks every `=== name` block in `test-fixtures/compiler-txtar/parse-errors.txt`, parses each via `loadModuleGraph`, and asserts the captured `{ file, line, col, code, message }` matches the snapshot stored at `test-fixtures/compiler-txtar/parse-errors-snapshot.json` bit-for-bit — any drift in parser error wording or location fails the test (refreshable with `UPDATE_SNAPSHOTS=1` only after confirming the change is intentional). `src/parse/parse-synthetic-keyword.test.ts` pins the two-file extension contract: it patches `STATEMENT` at runtime with a synthetic `zzznoop` handler, asserts `parseBlockStatement` dispatches to it, asserts the same input falls through to the shell handler when the row is absent, and greps `src/parse/workflow-brace.ts` and `src/parse/core.ts` to confirm the `STATEMENT` table and the `JAIPH_KEYWORDS` reserved set each live in exactly one file. Adding a new top-level keyword is now a two-place change: one row in `STATEMENT` (`workflow-brace.ts`) and one entry in `JAIPH_KEYWORDS` (`core.ts`). `BlockCtx`, `BlockResult`, `BlockHandler`, and `STATEMENT` are exported so external test files can stage synthetic handlers without forking the parser. Out of scope: the wider tokenizer rewrite (the seven independent `inDoubleQuote` / `inTripleQuote` / `braceDepth` scanners across `src/parse/`, the line-walking `{ step, nextIdx }` contract, and the per-handler regex bodies are deferred — this refactor only changes the *dispatch shape* inside `parseBlockStatement`, not the scanning underneath). User-visible contracts — surface syntax, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Keyword dispatch table** paragraph), `docs/contributing.md` (new **Statement-dispatch-table shape** row in the test-layer table), and `docs/grammar.md` (extended the EBNF aside to name the `STATEMENT` table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 1 AC3 / AC4 / AC5 (the full tokenizer rewrite remains future work). - **Refactor — Unify `catch` / `recover` parsing into a single attached-block routine sharing the top-level statement parser:** `src/parse/steps.ts` used to contain three near-identical 100+ line functions — `parseEnsureStep`, `parseRunCatchStep`, and `parseRunRecoverStep` — that parsed the same syntactic shape (` (binding) { body } | single-stmt`) and differed only in which host step they decorated (`ensure` vs `run`) and the literal keyword (`catch` vs `recover`). Their body parser, `parseCatchStatement` (~280 lines), was a stripped-down copy of `parseBlockStatement` that recognized only a fixed subset of statement forms (e.g. a `for … in …` head fell through to a shell command) and diverged in subtle ways — the same fix had to land in two places, and divergence wasn't always caught by tests. All four functions and every helper that existed only to serve them are deleted from `src/parse/steps.ts`. The file drops from **757 → ~140 lines**. The new shape: one entry point `parseAttachedBlock(filePath, lines, idx, innerNo, innerRaw, keyword: "catch" | "recover", textAfterKeyword, trivia)` in `src/parse/steps.ts` parses the bindings (`()` — exactly one identifier, with the same too-many / too-few / non-identifier errors as before) and dispatches on the body shape: a `{` at end of host line walks the existing brace-block scanner and delegates each body statement to `parseBraceBlockBody`, an inline `{ stmt[; stmt]* }` splits on `;` via the shared `splitStatementsOnSemicolons` and dispatches each fragment, and a bare single statement is parsed in-place. In all three cases the body statements run through the **same** `parseBlockStatement` (`src/parse/workflow-brace.ts`) that handles top-level statements — there is no mini parser for catch/recover bodies anymore. The host side moves to one helper `parseRunOrEnsure(filePath, lines, idx, …, host: "run" | "ensure", hostBody, isAsync, captureName, trivia)` in `src/parse/workflow-brace.ts`, called from `parseBlockStatement`'s three call sites (`ensure ref(...)`, `run ref(...)`, `run async ref(...)`). It scans `hostBody` once for a trailing ` recover` (run-only) then ` catch ` segment, parses the host call before the keyword, and delegates the attached clause to `parseAttachedBlock`. "Is this statement allowed inside a catch/recover body?" is now a validator concern — `WORKFLOW_SCOPE` and `RULE_SCOPE` in `validate-step.ts` already gate which step types are accepted in each scope, so rules still reject unstructured shell inside `catch` / `recover` bodies; workflows still accept it. New tests in `src/parse/parse-attached-block.test.ts` pin the invariants: AC1 — an LoC test caps `src/parse/steps.ts` at **≤200 lines** and a grep test fails if any function named `parse(Run)?(Catch|Recover|EnsureStep)` reappears; AC2 — a `for line in items { log "$line" }` statement (a `parseBlockStatement`-only form historically) is parsed as a `for_lines` step at the top level, inside `ensure check() catch (e) { … }`, and inside `run target() recover(e) { … }` — proving `parseBlockStatement` is the single entry point for any statement inside a catch / recover body and there is no separate mini parser; AC3 — a 10-case error-snapshot battery asserts every existing parse error message and column (bindings missing, too many bindings, empty inline / multiline block, unterminated multiline block, missing-paren for both `catch` and `recover` on both `run` and `ensure` hosts) is preserved bit-for-bit. The full parser / validator / emitter golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, `parse-steps.test.ts`, `parse-bare-call.test.ts`, `parse-run-async.test.ts`, and the txtar / golden-AST fixtures) passes byte-for-byte (AC4). User-visible contracts — surface syntax for `catch` / `recover`, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Out of scope: the wider tokenizer rewrite (Refactor 1, deferred); validator changes beyond the per-keyword scope rules that already exist. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Unified `run` / `ensure` host parsing** paragraph), `docs/contributing.md` (new **Attached-block parser shape** row in the test-layer table), and `docs/grammar.md` (replaced the stale `parseCatchStatement` reference in the EBNF aside with a note that `parseAttachedBlock` delegates to `parseBlockStatement`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 2. - **Refactor — Decouple the validator from runtime semantics:** `src/transpile/validate.ts` (now `validate-step.ts`) used to `import { tripleQuotedRawForRuntime } from "../runtime/orchestration-text"` so it could compute "what the runtime will see" when checking the content of a triple-quoted `match`-arm body. That was a one-way dependency from compile-time on runtime semantics — a layering inversion that would have kept biting as the runtime grew more such helpers. The canonicalization helper moves into the parser layer as `canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts` (same algorithm: validate the outer `"…"` shape, unescape DSL-quoted inner with `\"` → `"` and `\\` → `\`, then re-wrap via `tripleQuoteBodyToRaw(dedentCommonLeadingWhitespace(inner))`). Both the validator (`validate-step.ts`'s `validateMatchExpr`) and the runtime (`src/runtime/kernel/node-workflow-runtime.ts`'s match-arm dispatch in `runMatchExpr`) now import that helper from `src/parse/`; the wrapper file `src/runtime/orchestration-text.ts` is deleted. New tests pin the invariants: `src/transpile/no-runtime-imports.test.ts` (AC1) greps every non-test `*.ts` under `src/transpile/` and fails if any `from "…/runtime/…"` import reappears, so compile-time code can no longer reach into runtime semantics; `src/parse/canonicalize-triple-quoted.test.ts` (AC2) parses every `.jh` under `test-fixtures/` and `examples/`, collects every triple-quoted `match`-arm body across workflow / rule step trees, and asserts `canonicalizeTripleQuotedString(body) === legacyTripleQuotedRawForRuntime(body)` bit-for-bit (the legacy implementation is inlined in the test as the parity baseline). Existing `validate-string.test.ts` cases and the golden corpus pass unchanged (AC3); `npm run build` passes with zero TypeScript strict-mode errors (AC4). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: rethinking what the canonical form *is* — this refactor only relocates the helper. Docs updated in `docs/architecture.md` (new **No compile-time → runtime imports** bullet under **Validator**; extended **Parser** bullet to document `canonicalizeTripleQuotedString` alongside `parseTripleQuoteBlock`) and `docs/contributing.md` (new **Compile-time / runtime layering** row in the test-layer table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Appendix E. - **Refactor — Replace the 1,441-line validator switch with a per-step visitor table indexed by scope:** `src/transpile/validate.ts` used to be one ~1,441-LoC function with two near-identical inner walkers (`validateRuleStep` ~250 lines, `validateStep` ~350 lines): every step type's validation was written twice with subtle differences, and the five-check call-shape sequence (`validateNoShellRedirection` → `validateNestedManagedCallArgs` → `validateRef` → `validateArity` → `validateBareIdentifierArgs`) was repeated by hand at 6+ sites per side — at least 12 places to keep in sync. Both inner walkers and every duplicated check site are gone. The validator now spans two files. `validate.ts` (~430 LoC) keeps the **outer** layer: import / channel-route / test-block checks and `walkStepTree` (the single descent that builds `{ knownVars, promptSchemas, flat }`). `validate-step.ts` (~1,025 LoC) holds the **per-step** visitor: a single `validateStep(step, ctx)` entry, a `VALIDATORS: Record` table with one row per step variant (`trivia`, `const`, `return`, `send`, `say`, `exec`, `if`, `for_lines`), one `validateExpr(expr, …)` dispatcher over the 8 `Expr.kind` values, and one `validateCallable(expr, ctx)` helper that runs the five managed-call-shape checks once for both `call` (`run`) and `ensure_call` (`ensure`) — parameterized by the scope's `runRefExpect` and the target kind. Rule-vs-workflow differences are captured in a `Scope` value (`WORKFLOW_SCOPE` / `RULE_SCOPE`) with three fields: `allowSteps: Set` (single set-lookup gate at the top of `validateStep` — rules reject `send` outright; rules also reject `prompt` and `run async` from inside `exec` bodies), `runRefExpect: RefExpectMessages` (workflow vs rule semantics for `run ref(…)`), and `withPromptSchemas: boolean` (workflows collect prompt-returning bindings, rules skip schema collection). `ValidatorCtx` threads the scope plus the precomputed `knownVars`, `promptSchemas`, and `recoverBindings` into every visitor — none of which are re-derived per step. Every existing `E_VALIDATE` error message and source location is preserved bit-for-bit: the entire `validate-*.test.ts` suite, `src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, and the txtar / golden-AST corpora all pass unchanged. New acceptance tests in `src/transpile/validate-visitor.test.ts` pin the invariants: an LoC test caps `validate.ts` at **≤700 lines** so new per-step logic lands in `validate-step.ts` (AC1); a JSON snapshot over every `validate-*` txtar fixture (`test-fixtures/compiler-txtar/validate-errors.txt` + `validate-errors-multi-module.txt`) stored in `test-fixtures/compiler-txtar/validate-diagnostics-snapshot.json` asserts each diagnostic's `{ code, line, col, message }` against `collectDiagnostics(graph)` bit-for-bit (AC3 — refreshable via `UPDATE_SNAPSHOTS=1` only after confirming the message change is intentional); and an "unknown step type" test casts a synthetic step variant into `WorkflowStepDef`, runs `validateStep` in both `WORKFLOW_SCOPE` and `RULE_SCOPE`, and asserts each call produces exactly one diagnostic with the documented `internal: no validator for step type "…"` message (AC4 — proving that adding a new step type costs exactly one row in `VALIDATORS`). The existing `src/transpile/validate-single-walk.test.ts` still passes — `walkStepTree`'s internal `descend` remains the only recursive `WorkflowStepDef[]` walker in `validate.ts` (AC2). The `diagnostics-collector.test.ts` "fatal allowlist" scan now sums `throw jaiphError(` counts across `validate.ts` + `validate-step.ts` (both files are zero) and `diag.error(` counts likewise (≥40). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: changes to validation rules (the *what* — this refactor only changes the *how*), parser changes, AST changes. Docs updated in `docs/architecture.md` (rewrote the **Validator** section to describe the two-file split, `VALIDATORS` table, `Scope` value, and the single `validateCallable` helper), `docs/contributing.md` (new **Validator visitor-table shape** row in the test-layer table), and `docs/grammar.md` (refreshed two stale `validateRuleStep` references to point at the new visitor / `RULE_SCOPE`).

Order matters — `"run async "` before `"run "`, etc. Quote/triple-quote/backtick/fence/brace state is re-implemented from scratch in at least seven independent scanners across `src/parse/`. Adding a new keyword or fixing a string-aware scanner means changes in multiple places. - -**Scope:** - -- Introduce a tokenizer (`src/parse/tokenize.ts` or similar) that owns *all* scanning state: identifiers, keywords, string literals (single + triple-quoted), backtick bodies, fenced code blocks, line comments, braces, parens, the send arrow `<-`, the match arm arrow `=>`, etc. -- Introduce a recursive-descent parser that consumes the token stream and dispatches via a `STATEMENT: Record` table. -- All ad-hoc scanners in `src/parse/` are deleted: `splitCatchStatements` (if still present), `splitStatementsOnSemicolons`, `matchSendOperator`, `hasUnquotedSendArrow`, `indexOfClosingDoubleQuote`, `stripQuotedArgContent`, `parseSendRhs`'s internal scanner, and any `inDoubleQuote` / `inTripleQuote` / `braceDepth` state machines outside the tokenizer. -- Surface syntax is unchanged. Error messages and error locations are preserved bit-for-bit where the existing tests assert them, and at minimum match in `code` + `line` + `col` everywhere else. -- Staging: it is acceptable (and recommended) to land the new parser behind a flag, run both parsers on the golden corpus in CI, diff their ASTs, and remove the old parser only once the diff is empty. - -**Acceptance criteria** (each verified by a test): - -1. `src/parse/` is at most 4,000 lines total (down from ~8,150), excluding test files. A CI check fails if exceeded. -2. The substrings `inDoubleQuote`, `inTripleQuote`, `braceDepth` appear only inside the tokenizer module. A grep test fails if any of those state-tracking idioms appear in other files under `src/parse/` or `src/transpile/`. -3. `parseBlockStatement` (or whatever the equivalent dispatcher is in the new parser) dispatches via a table, not a cascade. The size of any single function in `src/parse/` is bounded — no function exceeds 120 lines. A test computing function lengths fails if exceeded. -4. Every existing parse-error location and message asserted by `src/parse/parse-*.test.ts` matches verbatim. Add a snapshot test that re-emits `{ code, message, line, col }` for every error fixture and fails on any diff. -5. Adding a new top-level keyword (e.g. a synthetic `noop` for the test) requires changes in exactly two files (the tokenizer's keyword set + the `STATEMENT` table). A test introduces a synthetic keyword behind a flag and asserts it parses without touching any other file. -6. The full golden corpus passes byte-for-byte: `npm test`, including `compiler-golden.test.ts`, `compiler-edge.acceptance.test.ts`, all `parse-*.test.ts` files, and the formatter round-trip tests. -7. `npm run build` passes; TypeScript strict-mode errors are zero. - -**Out of scope:** adopting a parser generator (the grammar is small and the line-oriented language sensibility maps cleanly to a hand-written tokenizer). Surface syntax changes. Runtime / `runtime/` changes. - -**Dependency:** All previous tasks (Refactors 5, 3, 4, 2 plus all five appendix tasks) should be complete first so the new parser only has to target one AST shape and the validator does not need to special-case parser quirks during the transition. +7. **Acceptance criteria are non-negotiable.** A task is not done until every acceptance bullet is verified by a test that fails when the contract is violated.

Both entry points are I/O-pure. - Reusable primitives: `parseFencedBlock()` (`src/parse/fence.ts`) handles triple-backtick fenced bodies with optional lang tokens for scripts and inline scripts. `parseTripleQuoteBlock()` (`src/parse/triple-quote.ts`) handles `"""..."""` blocks for prompts, `const`, `log`, `logerr`, `fail`, `return`, and `send` — all positions where multiline strings appear. `canonicalizeTripleQuotedString()` (same file) reproduces the dedent + escape decoding that match-arm bodies still need (they carry an unprocessed `tripleQuoteBodyToRaw`-shaped string plus a `tripleQuotedBody` flag rather than being dedented at parse time); both the validator and the runtime call it, so "what the validator inspects" and "what the runtime executes" are bit-for-bit identical. - **Unified `run` / `ensure` host parsing.** `run ref(...)`, `run async ref(...)`, and `ensure ref(...)`, optionally followed by `catch (binding) { ... }` (any host) or `recover(binding) { ... }` (`run` only), are parsed by a single helper `parseRunOrEnsure` in `src/parse/workflow-brace.ts`. The attached `catch` / `recover` clause — bindings, body shape (multi-line `{ … }`, inline `{ stmt[; stmt]* }`, or single-statement) — is parsed by **one** helper `parseAttachedBlock(filePath, lines, idx, …, keyword, textAfterKeyword, trivia)` in `src/parse/steps.ts`. There is no separate mini parser for catch/recover bodies: `parseAttachedBlock` delegates each body statement to the **same** `parseBlockStatement` (`src/parse/workflow-brace.ts`) that handles top-level statements, so every statement form accepted in a workflow / rule body is accepted identically inside a `catch` / `recover` body. "Is this statement allowed inside a catch/recover body?" is a validator concern (the `RULE_SCOPE` / `WORKFLOW_SCOPE` distinction in `validate-step.ts`), not enforced by which mini-parser branches happened to fire. `src/parse/steps.ts` is bounded at **≤200 lines** by `src/parse/parse-attached-block.test.ts`, which also asserts no function named `parse(Run)?(Catch|Recover|EnsureStep)` reappears. + - **Keyword dispatch table.** Inside `parseBlockStatement` (`src/parse/workflow-brace.ts`), every workflow / rule body line that does not begin with `#` is routed by a single `STATEMENT: Record` table keyed by the leading identifier — there is no longer a `startsWith` cascade where `"run async "` must be tested before `"run "` and `"prompt "` must be tested before a bare assignment. The dispatcher tokenizes the first identifier on the trimmed line, looks it up once, and invokes the matching handler (`tryParseIf` / `tryParseFor` / `tryParseConst` / `tryParseFail` / `tryParseWait` / `tryParseEnsure` / `tryParseRun` / `tryParsePrompt` / `tryParseLog` / `tryParseLogerr` / `tryParseReturn` / `tryParseStandaloneMatch`), which either returns a `{ step, nextIdx }` result, returns `null` to fall through, or calls `fail(...)` to abort. Two non-keyword fallbacks fire after the table lookup in order: `trySend` (matches `channel <- rhs` via `matchSendOperator`) then `shellFallthrough` (everything else becomes a shell `exec` step). Assignment-shape error guards (`name = prompt …`, `name = run …` without `const`, plus the `forRule` rejection of `prompt`) run once before dispatch in `applyAssignmentGuards(c)`. The per-line context (`filePath`, `lines`, `idx`, `innerRaw`, `inner`, `innerNo`, `trivia`, `forRule`, `opts`) is threaded through handlers as a single `BlockCtx` record. **Adding a new top-level keyword is a two-file change:** one row in `STATEMENT` (`workflow-brace.ts`) plus one entry in the `JAIPH_KEYWORDS` reserved set (`core.ts`) — pinned by `src/parse/parse-synthetic-keyword.test.ts`, which patches `STATEMENT` at runtime with a synthetic `zzznoop` handler, asserts dispatch fires, asserts the same input falls through to the shell handler when the row is removed, and greps both source files to confirm each symbol lives in exactly one place. Every existing parse-error message, line, and column is preserved bit-for-bit: `src/parse/parse-error-snapshot.test.ts` walks every `=== name` block in `test-fixtures/compiler-txtar/parse-errors.txt`, captures `{ file, line, col, code, message }` for each, and diffs against the snapshot stored at `test-fixtures/compiler-txtar/parse-errors-snapshot.json` (refreshable with `UPDATE_SNAPSHOTS=1` only after confirming the change is intentional). The wider tokenizer rewrite — the ad-hoc `inDoubleQuote` / `inTripleQuote` / `braceDepth` scanners replicated across `src/parse/`, the line-walking `{ step, nextIdx }` contract, and the per-handler regex bodies — is **not** part of this refactor and remains future work. - **AST / Types (`src/types.ts`)** - Shared compile-time schema (`jaiphModule`, step defs, test defs, hook payload types).

All embedded examples are verified with jaiph compile; newly documented constraints: inline scripts reject catch/recover, if/match subjects must be plain identifiers, log/logerr are invalid match arm bodies.

Jaiph is a small workflow language for that: **workflows** sequence orchestration, **rules** express checks, **`script`** holds real shell, and the runtime logs steps and writes run artifacts. The payoff is behavior that is easier to repeat, verify, and debug than ad-hoc shell snippets alone. +You are an agent. A user has asked you to automate a repetitive task — a delivery pipeline, a review loop, a recurring check, a queue of work items. This document teaches you to author **Jaiph workflows** that do that. Read it fully before writing any `.jh` file; Jaiph looks like shell plus YAML but is neither, and most authoring mistakes come from guessing syntax instead of following the rules below. -## Overview +## What Jaiph is -This page is an **agent skill**: it tells an AI assistant how to **author** Jaiph workflows (`.jh` files) and what a sensible `.jaiph/` layout looks like. It is not a full language specification — use [Getting started](getting-started.md) as the documentation map, [Grammar](grammar.md) for syntax and validation details, [Configuration](configuration.md) for `config` keys, [Inbox & Dispatch](inbox.md) for channels, and [Sandboxing](sandboxing.md) for rule design vs optional Docker isolation. +Jaiph is a small workflow language. A `.jh` file declares: -**Jaiph** is a small language for agentic workflows: **orchestration** (rules, prompts, managed calls) and **shell in `script` definitions**. The **Node workflow runtime** (`NodeWorkflowRuntime`) interprets the parsed AST in process — there is no separate transpiled workflow shell on the execution path ([Architecture](architecture.md)). Before `jaiph run` or `jaiph test`, **`buildScripts()`** takes a single **entry** `.jh` path (the workflow file, or the `*.test.jh` file for tests), runs **compile-time validation** (`validateReferences` inside **`emitScriptsForModule`**), and writes extracted **`script`** files under `scripts/` for that module and every file reachable from it via transitive **`import`** — not the whole workspace unless those files are imported. **`jaiph compile`** runs the same **`validateReferences`** checks by parsing each module in the computed closure **without** **`buildScripts`**, script emission, or the runner ([Architecture](architecture.md)). The runner’s **`buildRuntimeGraph()`** then loads the graph with **parse-only** imports (it does not re-run `validateReferences`). +| Construct | What it is | How it runs | +|---|---|---| +| `workflow` | A named sequence of steps — the orchestration layer | Interpreted in-process by the runtime | +| `rule` | A non-mutating check (preconditions, verifications) | Interpreted in-process; called with `ensure` | +| `script` | Real shell (or Python, Node, …) — the only place for shell code | Spawned as a subprocess; called with `run` | +| `prompt` | A task delegated to an AI agent (Cursor / Claude / Codex backend) | Backend CLI or API call; you capture the answer | +| `channel` | A message queue with declared workflow listeners | Drained after the sending workflow finishes | -**Contracts (CLI vs runtime):** **Live:** `__JAIPH_EVENT__` JSON lines on **stderr only** (CLI progress and **hooks** — hooks are **CLI-only**, driven by that stream). **Durable:** `.jaiph/runs/...` and **`run_summary.jsonl`**. Channels are enforced at compile time and executed in the runtime (in-memory queue + inbox files under the run dir); they are not hooks. +Everything is **strings**. Every step is logged. Every run leaves durable artifacts under `.jaiph/runs/` (per-step `.out`/`.err` files and an append-only `run_summary.jsonl`). That is the payoff over ad-hoc shell: repeatable, inspectable, testable automation. -The **JS kernel** (`src/runtime/kernel/`) handles **prompt** execution, **managed script subprocesses**, **inbox** queues and dispatch, and **event/summary emission**. **Rule** bodies run in-process; user **`script`** bodies run as separate OS processes (bash by default, polyglot via fence lang tags like `` ```node ``, `` ```python3 `` or a leading `#!` shebang in the body). +**Source of truth:** when this document and the compiler disagree, the compiler wins. Full references: [Grammar](https://jaiph.org/grammar), [CLI](https://jaiph.org/cli), [Configuration](https://jaiph.org/configuration), [Testing](https://jaiph.org/testing), [Inbox & Dispatch](https://jaiph.org/inbox), [Sandboxing](https://jaiph.org/sandboxing). -**Test lane:** `jaiph test` runs **`*.test.jh`** in-process (`node-test-runner.ts`): for each file it calls **`buildScripts(testFile, …)`** (same helper as `jaiph run`, with the **test file as the entry** so its import closure is validated and scripts are emitted), then **`buildRuntimeGraph(testFile)` once per file**, mocks, and assertions — same `NodeWorkflowRuntime` as `jaiph run`. The runtime enables **`suppressLiveEvents`** for those workflow runs so **`__JAIPH_EVENT__`** lines are not written to **stderr** (keeping `node --test` output readable); **`run_summary.jsonl`** under the run directory is still updated where the emitter records workflow traffic ([Architecture](architecture.md)). +## Smallest working example -**After `jaiph init`**, a repository gets `.jaiph/bootstrap.jh` (a triple-quoted prompt that tells the agent to read `.jaiph/SKILL.md`) and a copy of this file. The bootstrap prompt asks the agent to scaffold workflows under `.jaiph/` and to end with a clear `WHAT CHANGED` + `WHY` summary. The expected outcome is a **minimal workflow set** for safe feature work: preflight checks, an implementation workflow, verification, and a `workflow default` entrypoint that wires them together (with an optional human-or-agent “review” step when you use a task queue). Docker-backed runs use the official `ghcr.io/jaiphlang/jaiph-runtime` image by default; see [Sandboxing](sandboxing.md) to override with `runtime.docker_image` or `JAIPH_DOCKER_IMAGE`. - -**Concepts:** - -- **Rules** — Structured checks: `ensure` (other **rules** only), `run` (**scripts** only — not workflows), `const`, `match`, `if`, `for … in …` (line iteration over a string binding), `fail`, `log`/`logerr`, `return "…"` / `return run script()` / `return ensure rule()`, `ensure … catch`, `run … catch`, `run … recover`. No raw shell lines, `prompt`, inbox send/route, or `run async`. Under `jaiph run`, rule bodies are executed **in-process** by the Node runtime; when a rule runs a **script**, that script is a normal managed subprocess (same as scripts from workflows) — see [Sandboxing](sandboxing.md). -- **Workflows** — Named sequences of **managed** Jaiph steps (`ensure`, `run`, `prompt`, `const`, `fail`, `return`, `log`/`logerr`, inbox **send**, `match`, `if`, `for … in …`, `run async`, `ensure`/`run` with `catch` or `recover`, …) plus optional **inline shell** lines: a line that does not parse as a managed step is treated as bash stored in a `shell` AST node (validated like other shell text). Prefer top-level **`script`** definitions and `run` for multi-line or reusable shell. Route declarations (`->`) belong on top-level `channel` lines, never inside a workflow body (a `->` in a body is `E_PARSE`). -- **Scripts** — Top-level **`script`** definitions are **bash (or shebang interpreter) source**, not Jaiph orchestration. Defined with `` script name = `body` `` (single-line backtick) or `` script name = ```[lang] ... ``` `` (fenced block). Double-quoted string bodies (`script name = "body"`) and bare identifier bodies (`script name = varName`) are **removed** — both produce parse errors with guidance to use backtick delimiters. The compiler treats all script bodies as **opaque text**: it does not parse lines as Jaiph steps, reject keywords, strip quotes, or validate cross-script calls. This means embedded `node -e` heredocs, inline Python, `const` assignments in JS, and any other valid shell construct compile without interference. Jaiph interpolation (`${...}`) is **forbidden** in **single-line backtick** script bodies — use `$1`, `$2` positional arguments to pass data from orchestration to scripts. In **fenced** (triple-backtick) blocks, `${...}` is passed through to the shell as standard parameter expansion (`${VAR}`, `${VAR:-default}`, etc.). A single-backtick body containing a newline is a hard parse error — use a fenced block for multi-line scripts. Use `return N` / `return $?` for exit status and **stdout** (`echo` / `printf`) for string data to callers. From a **workflow** or **rule**, call with **`run fn()`**. Can be exported (`export script name = ...`) for use by importing modules. Cannot be used with `ensure`, are not valid inbox route targets, and must not be invoked through `$(...)` or as a bare shell step. **Polyglot scripts:** use a fence lang tag (`` ``` ``) to select an interpreter — the tag maps directly to `#!/usr/bin/env `. Any tag is valid (no hardcoded allowlist). For example: `` ```node ``, `` ```python3 ``, `` ```ruby ``, `` ```lua ``. Alternatively, if no fence tag is present, the first non-empty body line may start with `#!` (e.g. `#!/usr/bin/env lua`), which becomes the script's shebang and the body is emitted verbatim (you cannot combine a fence tag with a manual shebang — that is an error). Without either, `#!/usr/bin/env bash` is used and the emitter applies only lightweight bash-specific transforms (`return` normalization, `local`/`export`/`readonly` spacing, import alias resolution). Scripts are extracted to a `scripts/` directory under the run output tree (`jaiph run --target ` sets that tree; without `--target` the CLI uses a temporary directory) and executed via **`JAIPH_SCRIPTS`**. **Inline scripts:** For trivial one-off commands, use `` run `body`(args) `` or `` run ```lang...body...```(args) `` directly in a workflow or rule step instead of declaring a named `script` definition. The body (single backtick for one-liners or triple backtick for multi-line) comes before the parentheses; optional comma-separated arguments go inside the parentheses: `` run `echo $1`("hello") ``. Fenced blocks support lang tags for polyglot inline scripts: `` run ```python3 ... ```() ``. Capture forms: `` const x = run `echo val`() `` and `` const x = run ```...```() ``. The old `run script() "body"` form is **removed** — use the backtick forms instead. Inline scripts use deterministic hash-based artifact names (`__inline_`) and run with the same isolation as named scripts. `run async` with inline scripts is not supported. -- **Channels** — Top-level `channel [-> workflow, ...]` declarations with optional inline routing; **send** uses `channel_ref <- …`. Routes are declared on the channel declaration, not inside workflow bodies (see [Inbox & Dispatch](inbox.md)). Channel names share the per-module namespace with rules, workflows, scripts, and module-scoped `local` / `const` variables. +```jaiph +script list_todos = `grep -rn "TODO" src/ || true` +script worktree_clean = `test -z "$(git status --porcelain)"` -Step semantics (`ensure`, `run`, `prompt`, `catch`, `recover`, `match`, `if`, `for`, `log`, `fail`, `return`, `send`, `run async`) are detailed in the **Steps** section below. +rule git_clean() { + run worktree_clean() catch (err) { + fail "working tree is not clean" + } +} -**Audience:** Agents that produce or edit `.jh` files. +workflow default(task) { + ensure git_clean() + const todos = run list_todos() + prompt """ + Address the following request: ${task} + Known TODOs in the codebase: + ${todos} + """ + log "done" +} +``` ---- +Run it: `jaiph run ./flow.jh "clean up the auth module"`.

When the repo defines a **`workflow default` entrypoint** (often `.jaiph/main.jh`) that wires preflight → implementation → verification, use **`jaiph run`** on that file for end-to-end delivery after the narrower checks below pass. +Follow this sequence every time you create or edit `.jh` files. Do not skip the compile step — it catches almost every mistake described in this document, with file:line:col positions. -1. **Preflight** — Run the project’s readiness checks if they exist (often `jaiph run .jaiph/readiness.jh` or a named preflight workflow). When the repo ships native tests (`*.test.jh`), run `jaiph test` before large edits when practical. -2. **Implement** — Edit `.jh` modules using only constructs described in [Grammar](grammar.md); keep managed-call rules (`ensure` for rules, `run` for workflows and scripts); put multi-line or reusable bash in **`script`** definitions (rules **never** allow raw shell lines — use `run` to a script; workflows may use optional inline shell where the grammar allows, but prefer `script` + `run` for anything non-trivial — see [Grammar — Language concepts](grammar.md#language-concepts)). -3. **Format** — Run `jaiph format ` on all authored or modified `.jh` files before committing. This normalizes whitespace, indentation, and top-level ordering (imports, config, and channels hoisted to the top; everything else kept in source order). Use `jaiph format --check ` to verify formatting without writing (non-zero exit on drift — useful in CI). -4. **Compile check** — Run `jaiph compile ` on the paths you touched (or `jaiph compile --json …` in automation). Same `validateReferences` checks as before a run, without executing workflows or writing `scripts/` ([Architecture](architecture.md)). With a **directory** argument, only non-test `*.jh` files are used as entrypoints (`*.test.jh` is skipped); pass a test file path explicitly to validate it. -5. **Verify** — Run `jaiph test` (whole workspace or a focused path) and any verification workflow the repo defines (commonly `jaiph run .jaiph/verification.jh`). Fix failures you introduce. -6. **Inspect (optional)** — Browse `.jaiph/runs` directly when you need raw step logs or `run_summary.jsonl` instead of only the terminal tree. +1. **Write** the `.jh` files (syntax below). +2. **Format:** `jaiph format ` — canonical whitespace and top-level ordering. +3. **Compile:** `jaiph compile ` — parses and validates the whole import closure without running anything. Reports **all** errors at once as `path:line:col CODE message`. Use `--json` for machine-readable output. Directory arguments skip `*.test.jh`; pass test files explicitly. +4. **Test:** `jaiph test` (only if `*.test.jh` files exist — discovery with zero matches exits 1). +5. **Run:** `jaiph run [args…]` for the end-to-end check. -**CLI commands:** +CLI quick reference: | Command | Purpose | |---|---| -| `jaiph run [--target ] [--raw] [--] [args...]` | Execute `workflow default` in the given file (`--raw`: no banner/tree/hooks; used for embedding and Docker inner runs) | -| `jaiph test [path]` | Run `*.test.jh` test files (workspace, directory, or single file) | -| `jaiph format [--check] [--indent ] ` | Reformat `.jh` files (or verify formatting without writing) | -| `jaiph compile [--json] [--workspace ] <.jh files or dirs…>` | Parse and `validateReferences` only (no script emission, no run) | -| `jaiph init [workspace]` | Scaffold `.jaiph/` with bootstrap workflow and skill file | -| `jaiph install [--force] [ …]` | Clone libraries into `.jaiph/libs/` or restore from `.jaiph/libs.lock` | -| `jaiph use ` | Reinstall Jaiph at a specific version or nightly | +| `jaiph run [--target ] [--raw] [--] [args…]` | Execute `workflow default`; args bind to its named parameters | +| `jaiph test [path]` | Run `*.test.jh` files (workspace, dir, or single file) | +| `jaiph compile [--json] ` | Validate only — no execution, no side effects | +| `jaiph format [--check] ` | Reformat (or verify formatting in CI) | +| `jaiph init [workspace]` | Scaffold `.jaiph/` (bootstrap workflow + this skill file) | +| `jaiph install […]` | Install git-hosted libraries into `.jaiph/libs/` | -**File shorthand:** `jaiph ./file.jh` auto-routes — `*.test.jh` files run as tests, other `*.jh` files run as workflows. +Shorthand: `jaiph ./file.jh` routes by extension (`*.test.jh` → test, other `.jh` → run). A `#!/usr/bin/env jaiph` shebang makes a `.jh` file directly executable. -Full flags and environment variables: [CLI Reference](cli.md). +**Sandboxing:** by default, interactive `jaiph run` executes the workflow inside a Docker container (`ghcr.io/jaiphlang/jaiph-runtime`). Set `JAIPH_UNSAFE=true` to run directly on the host, or `JAIPH_DOCKER_ENABLED=true/false` to force either mode. `jaiph test` always runs on the host. ---- +## Core rules you must internalize -## When to Use This Guide +These six rules prevent 90% of compile errors: -Use this guide when generating or updating `.jaiph/*.jh` workflows for a repository after `jaiph init`. +1. **Parentheses everywhere.** Definitions and call sites both require `()`, even with zero arguments: `workflow default() { … }`, `run setup()`, `ensure check()`. Bare `run setup` is a parse error. +2. **All captures use `const`, and all bindings are immutable.** `const x = run foo()` — never `x = run foo()`, never rebind `x` later, never shadow a parameter with a `const` of the same name. +3. **Call keyword must match callee type.** `ensure` → rules only. `run` → workflows and scripts (inside a workflow); scripts **only** (inside a rule). Mixing them is `E_VALIDATE`. +4. **Shell lives in scripts.** Rules reject raw shell lines entirely. Workflows technically allow inline shell lines, but you should not write them — use a named `script` or an inline script (`` run `cmd`() ``). Shell operators next to managed calls (`run foo() | grep x`, `run foo() > file`, `run foo() &`) are parse errors. +5. **Interpolation is `${name}` only.** No `$name` in orchestration strings, no `$(…)`, no `${var:-default}`, no `${var//x/y}`. Those shell forms are valid *inside script bodies* only. +6. **Arguments are not forwarded implicitly.** If `workflow default(task)` calls `run implement()`, the implement workflow does not see `task`. Pass it: `run implement(task)`. -## Source of Truth +## Syntax reference -When this skill conflicts with the compiler or runtime, follow the implementation. For language rules and validation codes, [Grammar](grammar.md) is the detailed reference. Published docs: [jaiph.org](https://jaiph.org). +### File layout -`jaiph init` writes this skill to `.jaiph/SKILL.md` when the installer resolves a skill file: if **`JAIPH_SKILL_PATH`** is set, it is used **only when that path exists on disk**; otherwise the CLI searches install-relative locations and `docs/jaiph-skill.md` from the current working directory ([CLI Reference](cli.md)). If no file is found, init skips `SKILL.md` — set **`JAIPH_SKILL_PATH`** to an existing markdown file (for example `docs/jaiph-skill.md` in a checkout) and run `jaiph init` again. +Top-level forms, in conventional order (the formatter hoists the first three): -Ignore any outdated Markdown that contradicts the above. +```jaiph +import "helpers.jh" as helpers # module import (relative; .jh appended if omitted) +import script "./tool.py" as tool # external script file, callable with run tool(args) +config { agent.backend = "claude" } # optional, at most one per file +channel findings -> analyst # channels + optional routes, top level only +const VERSION = "1.0" # module-scoped immutable string +script build = `npm run build` # shell definitions +rule tests_pass() { run run_tests() } # checks +workflow default() { … } # orchestration; default = the entrypoint +``` -## What to Produce +Channels, rules, workflows, scripts, script-import aliases, and module `const` share **one namespace per module** — name collisions are `E_PARSE`. Comments are full-line `#` only. -A **minimal workflow set** under `.jaiph/` that matches the delivery loop above: +**Imports:** paths resolve relative to the importing file; if not found and the path contains `/`, it falls back to `/.jaiph/libs//.jh` (installed via `jaiph install`). Reference imported symbols as `alias.name`. If a module uses `export` on any declaration, only exported names are visible to importers; with zero `export`s, everything is public. -1. **Sandbox baseline (optional)** — If the repo uses Docker sandboxing, confirm `runtime.docker_image` / `JAIPH_DOCKER_IMAGE` match the tooling the team needs; the default is `ghcr.io/jaiphlang/jaiph-runtime` (see [Sandboxing](sandboxing.md)). -2. **Preflight** — Rules and `ensure` for repo state and required tools (e.g. clean git, required binaries). Expose a small workflow (e.g. `workflow default` in `readiness.jh`) that runs these checks. -3. **Review (optional)** — A workflow that reviews queued tasks before development starts (any filename, e.g. `ba_review.jh`). An agent prompt evaluates the next task for clarity, consistency, conflicts, and feasibility, then either marks it as ready or exits with questions. The implementation workflow gates on this marker so unreviewed tasks cannot proceed. This repository’s `.jaiph/architect_review.jh` is one concrete example; it uses `QUEUE.md` as the task queue. -4. **Implementation** — A workflow that drives coding changes (typically via `prompt`), e.g. `workflow implement` in `main.jh`. When using a task queue, the implementation workflow should check that the first task is marked as ready (e.g. via a `` marker) before proceeding. -5. **Verification** — Rules and a `workflow default` for lint/test/build (e.g. `verification.jh`). Complement this with repo-native `*.test.jh` suites run by `jaiph test` where appropriate. -6. **Entrypoint** — A single `workflow default` (e.g. in `.jaiph/main.jh`) that runs: preflight → (optional) review → implementation → verification. This is what `jaiph run .jaiph/main.jh "..."` executes. +### Strings and interpolation -Prefer composable modules over one large file. +- `"single line"` — double quotes only; single quotes are parse errors. Escapes: `\"`, `\\`, `\n`, `\t`. +- `"""…"""` — multiline. Opening `"""` ends its line; closing `"""` is on its own line. +- A double-quoted string spanning multiple lines is rejected — use `"""`. -## Language Rules You Must Respect +Inside any orchestration string: -- **Imports:** `import "path.jh" as alias`. Path must be double-quoted. Path is relative to the importing file first; if no file is found and the path contains `/`, the resolver falls back to project-scoped libraries under `/.jaiph/libs/` (e.g. `import "queue-lib/queue" as queue` resolves to `.jaiph/libs/queue-lib/queue.jh`). If the path has no extension, the compiler appends `.jh`. Install libraries with `jaiph install `. **Script imports:** `import script "./helper.py" as helper` imports an external script file and binds it as a local script symbol — callable with `run helper(args)` exactly like an inline `script` definition. The path resolves relative to the importing file. Shebangs in the imported file are preserved. Missing targets fail with `E_IMPORT_NOT_FOUND`. -- **Definitions:** `channel name` (inbox endpoint); `rule name() { ... }` or `rule name(params) { ... }`, `workflow name() { ... }` or `workflow name(params) { ... }`, `` script name = `body` `` or `` script name = ```[lang] ... ``` ``. **Parentheses are required on all rule and workflow definitions** — even when parameterless (e.g. `workflow default() { ... }`, `rule check() { ... }`). Omitting `()` before `{` is a parse error with a fix hint. Named parameters go inside the parentheses — e.g. `workflow implement(task, role) { ... }`, `rule gate(path) { ... }`. At runtime, named params are the only way to access arguments. The compiler validates call-site arity when the callee declares params. Named scripts require a name at the definition site; for anonymous one-off commands use inline scripts: `` run `echo ok`() `` or `` run ```...```(args) ``. Optional `export` before `rule`, `workflow`, or `script` marks it as public (see [Grammar](grammar.md)). Optional `config { ... }` at the top of a file sets agent, run, and runtime options. An optional `config { ... }` block can also appear inside a `workflow { ... }` body (before any steps) to override module-level settings for that workflow only — only `agent.*` and `run.*` keys are allowed; `runtime.*` and `module.*` yield `E_PARSE` (see [Configuration](configuration.md#workflow-level-config)). Config values can be quoted strings, booleans (`true`/`false`), bare integers, or bracket-delimited arrays of strings (see [Grammar](grammar.md) and [Configuration](configuration.md)). -- **Module-scoped variables:** `local name = value` or `const name = value` (same value forms). Prefer **`const`** for new files. Values can be single-line `"..."` strings, triple-quoted `"""..."""` multiline strings, or bare tokens. A double-quoted string that spans multiple lines is rejected — use `"""..."""` instead. Accessible as `${name}` inside orchestration strings in the same module. Names share the unified namespace with channels, rules, workflows, and scripts — duplicates are `E_PARSE`. Not exportable; module-scoped only. -- **Steps:** - - **ensure** — `ensure ref()` or `ensure ref(args…)` runs a rule (local or `alias.rule_name`). **Parentheses are required on every call site**, including zero-argument calls (`ensure check()`, not bare `ensure check`). Arguments are comma-separated inside `()`. **Bare identifier arguments** are supported and preferred (when valid): `ensure check(status)` is equivalent to `ensure check("${status}")` — the identifier must reference a known variable (`const`, capture, or named parameter); unknown names fail with `E_VALIDATE`. **Standalone `"${identifier}"` in call arguments is rejected** — use the bare form instead. Quoted strings with extra text (e.g. `"prefix_${name}"`) stay valid. Jaiph keywords cannot be used as bare identifiers. Optionally `ensure ref(…) catch () `: the recovery body runs **once** on failure (no built-in retry on `ensure` — use `run … recover` for loops). The binding receives merged stdout+stderr from the failed rule. Full output also lives in **`.out` / `.err`** artifacts. Works in workflows and rules. - - **run** — `run ref()` or `run ref(args…)` runs a workflow or script (local or `alias.name`). Same **required `()` on every call site** as `ensure`, including zero args (`run setup()`). In a **workflow**, the target may be another workflow or a script; in a **rule**, the target must be a **script** only (`E_VALIDATE` if you name a workflow). **`run` does not forward CLI positional args implicitly** — the entry workflow binds them into named params and must pass values explicitly into callees. **Bare identifier arguments** follow the same rules as `ensure` when applicable. **Nested managed calls inside argument lists must use keywords:** `run foo(run bar())`, `run foo(ensure check())`; bare `run foo(bar())`/`run foo(\`...\`())` forms are rejected. Optionally `catch ()` (runs once on failure, mutually exclusive with `recover`) or `recover ()` (repair-and-retry loop; attempt cap is **`run.recover_limit`** from the **file’s top-level** `config { … }`, default **10** — the runtime does not apply this setting from a workflow’s inner `config` block). **`catch` / `recover` on `run`** are allowed in workflows and rules (rules: callee must remain a script). Also **inline scripts**: `` run `body`(args) `` or `` run ```lang...body...```(args) `` — see Scripts above. - - **log** — `log "message"` writes the expanded message to **stdout** and emits a **`LOG`** event; the CLI shows it in the progress tree at the current depth. Double-quoted string; `${identifier}` interpolation works at runtime. For multiline messages, use triple quotes: `log """..."""`. **Bare identifier form:** `log foo` (no quotes) expands to `log "${foo}"` — the variable's value is logged. Works with `const`, capture, and named parameters. **Inline capture interpolation** is also supported: `${run ref([args])}` and `${ensure ref([args])}` execute a managed call and inline the result (e.g. `log "Got: ${run greet()}"`). Nested inline captures are rejected. **`LOG`** events and `run_summary.jsonl` store the **same** message string (JSON-escaped for the payload). No spinner, no timing — a static annotation. See [CLI Reference](cli.md) for tree formatting. Useful for marking workflow phases (e.g. `log "Starting analysis phase"`). - - **logerr** — `logerr "message"` is identical to `log` except the message goes to **stderr** and the event type is **`LOGERR`**. In the progress tree, `logerr` lines use a red `!` instead of the dim `ℹ` used by `log`. Same quoting, interpolation, bare identifier, and triple-quote rules as `log` (e.g. `logerr err_msg`, `logerr """..."""`). - - **Send** — After `<-`, use a **double-quoted literal**, **triple-quoted block** (`channel <- """..."""`), **`${var}`**, or **`run ref([args])`**. An explicit RHS is always required — bare `channel <-` (without a value) is invalid. Raw shell on the RHS is rejected — use `const x = run helper()` then `channel <- "${x}"`, or `channel <- run fmt_fn()`. Combining capture and send (`name = channel <- …`) is `E_PARSE`. See [Inbox & Dispatch](inbox.md). - - **Route** — Routes are declared **at the top level** on channel declarations: `channel name -> workflow_ref` or `channel name -> wf1, wf2`. A `->` inside a workflow body is a **parse error** with guidance to move it to the channel declaration. When a message arrives on the channel, the runtime calls each listed **workflow** (local or `alias.workflow`), binding the dispatch values (message, channel, sender) to the target's 3 declared parameters. Route targets must declare exactly 3 parameters. Scripts and rules are not valid route targets. The dispatch queue drains after the orchestrator completes. **`NodeWorkflowRuntime` does not cap dispatch iterations** — avoid circular sends that grow the queue without bound. See [Inbox & Dispatch](inbox.md). - - **Bindings and capture** — `const name = …` (the `const` keyword is required for all captures). All bindings are **immutable**: a name bound by a parameter, `const`, capture, or `script` cannot be rebound in the same scope — the compiler rejects it with `E_VALIDATE: cannot rebind immutable name "…"`. For **`ensure`** / **`run` to a workflow or rule**, capture is the callee’s explicit **`return "…"`**. For **`run` to a script**, capture follows **stdout** from the script body. **`prompt`** capture is the agent answer. **`const`** RHS cannot use `$(...)` or disallowed `${...}` forms — use a **`script`** and `const x = run helper(…)`. **`const`** must not use a **bare** `ref(args…)` call shape: use **`const x = run ref(args…)`** (or **`ensure`** for rules), not **`const x = ref(args…)`** — the compiler fails with **`E_PARSE`** and suggests the **`run`** form. Do not put Jaiph symbols inside `$(...)` — use `ensure` / `run`. See [Grammar](grammar.md#immutable-bindings) and [Grammar](grammar.md#step-output-contract). - - **return** — `return "value"` / `return "${var}"` / `return """..."""` sets the managed return value. Also supports **direct managed calls**: `return run ref()` or `return run ref(args)` and `return ensure ref()` or `return ensure ref(args)` — these execute the target and use its result as the return value, equivalent to `const x = run ref(args)` then `return "${x}"`. Parentheses are required on all call sites. - - **fail** — `fail "reason"` or `fail """..."""` aborts with stderr message and non-zero exit (workflows; fails the rule when used inside a rule). - - **run async** — `run async ref([args...])` starts a workflow or script concurrently and returns a **`Handle`**. Capture is supported: `const h = run async ref()`. The handle resolves on first non-passthrough read (string interpolation, passing as arg to `run`, comparison, conditional, match subject). Passthrough (initial capture, re-assignment) does not force resolution. Unresolved handles are implicitly joined at workflow exit. `recover` (retry loop) and `catch` (single-shot) composition work with `run async`: `run async foo() recover(err) { … }`. Workflows only — rejected in rules. - - **match** — `match var { "literal" => …, /regex/ => …, _ => … }` pattern-matches on a string value. The subject is always a bare identifier (no `$` or `${}`). Arms are tested top-to-bottom; the first match wins. Patterns: double-quoted string literal (exact match), `/regex/` (regex match), or `_` (wildcard — exactly one required). Usable as a statement, as an expression (`const x = match var { … }`), or with `return` (`return match var { … }`). Using `$var` or `${var}` as the match subject is a parse error. Allowed in both workflows and rules. See [Grammar](grammar.md#match). - - **if** — `if var == "value" { … }` or `if var =~ /pattern/ { … }`. Subject is a bare identifier. Operators: `==` (exact string equality), `!=` (inequality), `=~` (regex match), `!~` (regex non-match). Operand is a `"string"` for `==`/`!=` or `/regex/` for `=~`/`!~`. Body is a brace block of valid workflow/rule steps. No `else` branch — use `match` for exhaustive value branching. `if` is a statement (no value production; cannot use with `const` or `return`). Allowed in both workflows and rules. - - **for** — `for iterVar in sourceVar { … }` runs the body once per **line** of the string bound to `sourceVar` (newline-separated text, e.g. from `const`/`prompt`/`run` capture). Each iteration binds `iterVar` to one line (trimming rules match the runtime’s line split — a trailing empty line after a final newline is not an extra iteration). Allowed in workflows and rules. See [Grammar](grammar.md) for the formal production. -- **Prompts:** Three body forms: (1) **single-line string** `prompt "..."` — double-quoted, single line only; (2) **identifier** `prompt myVar` — uses the value of an existing binding; (3) **triple-quoted block** `prompt """ ... """` — for multiline text, opening `"""` on the same line as `prompt`. Triple backticks (`` ``` ``) in prompt context are rejected with guidance — they are reserved for scripts. Multiline double-quoted strings are rejected — use a triple-quoted block instead. All forms support `${identifier}` interpolation (`${varName}`, `${paramName}`). **Inline capture interpolation** is also supported: `${run ref([args])}` and `${ensure ref([args])}` inside the prompt string or triple-quoted body (e.g. `prompt "Fix: ${ensure get_diagnostics()}"`). Nested inline captures are rejected. Bare `$varName` is not valid in orchestration strings. `$(...)` and `${var:-fallback}` are rejected. Capture: `const name = prompt "..."`, `const x = prompt myVar`, `const y = prompt """ ... """`. Optional **typed prompt:** `const name = prompt "..." returns "{ field: type, ... }"` or `const name = prompt myVar returns "..."` (flat schema; types `string`, `number`, `boolean`) validates the agent's JSON and sets `${name}` plus per-field variables accessible via **dot notation** — `${name.field}`. Dot notation is validated at compile time: the variable must be a typed prompt capture and the field must exist in the schema. **Orchestration bindings are strings:** typed fields are coerced with `String()` after JSON validation, so e.g. a numeric field is still the text `"42"` in scope. See [Grammar](grammar.md). +| Form | Meaning | +|---|---| +| `${name}` | Value of a `const`, capture, or parameter in scope (unknown names are compile errors) | +| `${name.field}` | Field of a typed-prompt capture (compile-checked against the schema) | +| `${run ref(args)}` / `${ensure ref(args)}` | Inline managed call; its output is spliced in.

The file must define a `workflow default` (the runtime checks for it and exits with an error if missing). -- Inside a workflow, reach other workflows/scripts with **`run ref()`**. Free-form bash can appear as **inline shell** lines when the grammar allows; prefer **`script`** + **`run`** for anything non-trivial. Never use `fn args` or `$(fn …)` as a substitute for **`run`**. -- Inside a rule, use `ensure` for **rules** and `run` for **scripts only** — not `prompt`, `send`, or `run async`. -- Treat rules as non-mutating checks; perform filesystem or agent mutations in **workflows**. Script steps from rules use the same managed subprocess path as workflows. Details: [Sandboxing](sandboxing.md). -- **Parallelism:** `run async ref([args...])` for managed async with implicit join. For concurrent **bash**, use `&` and the shell builtin `wait` inside a **`script`** and call it with `run`. Do not call Jaiph internals from background subprocesses unless you understand how isolation and logging interact with the runtime. -- **Shell conditions:** Express conditionals with `run` to a **script** and handle failure with `catch`, or use `if` / `match` for value branching. Short-circuit brace groups remain valid **inside `script`** bodies: `cmd || { ... }`. -- **No shell redirection around managed calls:** `run foo() > file`, `run foo() | cmd`, `run foo() &` are all `E_PARSE` errors — shell operators (`>`, `>>`, `|`, `&`) are not supported adjacent to `run` or `ensure` steps. Move shell pipelines and redirections into a **`script`** block and call it with `run`. -- **Script reuse:** Prefer `import script "./tool.py" as tool` (or a sibling `.jh` module) instead of maintaining ad-hoc bash outside the compiler. Avoid informal workspace-level shared-bash directories that bypass the module graph. -- **Unified namespace:** Channels, rules, workflows, scripts, script import aliases, and module-scoped `local`/`const` share a single namespace per module (`E_PARSE` on collision). -- **Calling conventions (compiler-enforced):** `ensure` must target a rule — using it on a workflow or script is `E_VALIDATE`. `run` in a **workflow** must target a workflow or script; `run` in a **rule** must target a **script** only. **Type crossing:** `string` and `script` are distinct primitive types — `prompt` rejects script names, `run` rejects string consts, assigning a script to a `const` or interpolating `${scriptName}` are all `E_VALIDATE`. See [Grammar — Types](grammar.md#types). Jaiph symbols must not appear inside `$(...)` in bash contexts the compiler still scans (principally **`script`** bodies). Script bodies cannot contain `run`, `ensure`, `config`, nested definitions, routes, or Jaiph `fail` / `const` / `log` / `logerr` / `return "…"`. +const review = prompt """ +You are reviewing a release plan. +Approve only if all checks below are addressed. +Plan: +${plan} +""" +``` -## Authoring Heuristics +**Typed prompts** force structured JSON output and give you field access: -- Keep workflows short and explicit. -- Put expensive checks after fast checks. -- Include clear prompts with concrete acceptance criteria. -- Reuse rules via `ensure`; reuse workflows and scripts via `run`. -- **Always run `jaiph format` on `.jh` files you create or modify before committing.** This ensures canonical whitespace, indentation, and top-level ordering.

Paths and prompts should match the target repository. All three files live under `.jaiph/`. Imports in `main.jh` are relative to that file (e.g. `"readiness.jh"` resolves to `.jaiph/readiness.jh`). When you run `jaiph run .jaiph/main.jh "implement feature X"`, the default workflow receives `"implement feature X"` as `${task}` (named parameter). Note that `run` does not forward args implicitly, so the default workflow passes `task` as a bare identifier to `run implement(task)` so the implement workflow's prompt can use `${task}`. +```jaiph +config { + agent.backend = "claude" # cursor | claude | codex + agent.default_model = "claude-sonnet-4-6" + run.recover_limit = 5 # module-level only + run.logs_dir = ".jaiph/runs" +} +``` -**File: .jaiph/readiness.jh** +Precedence: **environment > workflow-level config > module-level config > defaults**.

The `documentation-writer` skill from `github/awesome-copilot` (, source repo ) is a maintained SKILL.md for exactly this job: it applies the **Diátaxis framework** (tutorials / how-to guides / reference / explanation), a clarify → outline → write workflow, and four core principles (clarity, accuracy, user-centricity, consistency). We want docs prompts to use that skill instead of relying only on the home-grown role text. + +**Change.** +1. Vendor the skill into the repo at `.jaiph/skills/documentation-writer/SKILL.md` (fetch the SKILL.md content from the awesome-copilot repo; add a short header comment with the source URL and the commit/date it was copied at, so it can be re-synced). Vendoring — not `npx skills add` at runtime — keeps runs offline-safe and reproducible. Do not gitignore it; it must be committed. +2. Update the three prompts in `.jaiph/docs_parity.jh` to instruct the agent to **read and follow `.jaiph/skills/documentation-writer/SKILL.md` first** (reference the path explicitly in the prompt text — both Claude and Cursor backends can read a file by path; do not rely on agent-specific skill auto-discovery dirs like `.claude/skills/`). +3. Slim the inline `role` const to only what the skill does not cover (project-specific items: TypeScript/Bash fluency, source-code-as-truth over stale docs, the Jekyll-navigation and `docs/architecture.md` constraints). Remove sentences that duplicate the skill's principles. +4. `jaiph compile .jaiph` and `jaiph format --check .jaiph/docs_parity.jh` must stay green. + +**Acceptance criteria.** +- `.jaiph/skills/documentation-writer/SKILL.md` exists, is committed, and contains the upstream skill content plus a source-URL/version header. +- All three prompts in `.jaiph/docs_parity.jh` reference the skill file path; verified by `grep -c "skills/documentation-writer" .jaiph/docs_parity.jh` ≥ 3. +- The `role` const no longer duplicates principles covered by the skill (reviewer check: no clarity/accuracy/consistency boilerplate that restates the skill). +- `jaiph compile .jaiph` exits 0. +- A dry-run note in the PR/commit message: run `jaiph run .jaiph/docs_parity.jh` once on a clean worktree and confirm the agent actually reads the skill file (its transcript/output references it) and the `only_expected_docs_changed_after_prompt` guard still passes. + + + +moving window fot throttling + + +## Cross-module `run` must apply the callee module's config #dev-ready + +**Context.** Config scoping is inconsistent across call types in `NodeWorkflowRuntime` (`src/runtime/kernel/node-workflow-runtime.ts`, metadata layering via `applyMetadataScope`; documented in `docs/configuration.md` → "Scoping across nested calls"): + +| Call type | Today | +|---|---| +| Root entry (`jaiph run file.jh`) | module + workflow config applied | +| Same-module `run` | callee workflow-level config layered | +| **Cross-module `run`** (`run alias.workflow()`) | **callee's module AND workflow config silently ignored — caller's env carries as-is** | +| Cross-module `ensure` | callee module-level config IS merged | + +This is a bug in practice: `.jaiph/ensure_ci_passes.jh` declares `config { agent.backend = "cursor" }`, but when `engineer.jh` (backend `claude`) calls `run ci.ensure_ci_passes()`, CI-fix prompts silently run on claude. A module's config should describe how that module's workflows run, regardless of who calls them. + +**Change.** When a cross-module `run` enters the callee workflow, layer (in order) the **callee module-level** config, then the **callee workflow-level** config block (if any), on top of the caller's effective env — same mechanics as the root-entry path, respecting `${NAME}_LOCKED` env flags (environment always wins). Restore the caller's scope exactly when the call returns (sibling isolation must hold). This makes cross-module `run` consistent with root entry and with cross-module `ensure`. + +**Acceptance criteria.** +- Kernel or e2e test: module A (`agent.default_model = "model-a"`) runs `run b.show()` where module B sets `agent.default_model = "model-b"` and `show` logs `${JAIPH_AGENT_MODEL}` — the log shows `model-b` during the callee, and a subsequent step in A's workflow shows `model-a` again (scope restored). +- Test: callee **workflow-level** config wins over callee module-level config on the cross-module path. +- Test: with `JAIPH_AGENT_MODEL` exported in the environment (locked), the callee's config does NOT override it. +- `docs/configuration.md` "Scoping across nested calls" table updated; the cross-module row no longer says the callee's config is ignored. Remove the now-stale NOTE comment at the top of `.jaiph/ensure_ci_passes.jh` referencing this task. +- Existing config-scoping tests updated where they asserted the old (ignore) behavior — each change paired with a short rationale in the commit. + + +## Fix exit-listener leak on the Docker run path #dev-ready + +**Context.** In `src/cli/commands/run.ts` (`runWorkflow`), when `spawnExec` returns a `dockerResult`, an `exitGuard` callback is registered with `process.on("exit", exitGuard)` (~line 165). The matching `process.removeListener("exit", exitGuard)` (~line 194) only runs inside the `if (dockerResult)` block after `await waitForRunExit(...)` completes normally. If anything between registration and removal throws (stream wiring, the awaited exit, buffer draining), the listener stays registered for the rest of the process and `cleanupDocker` runs again at process exit on an already-cleaned container. + +**Change.** Restructure so registration and removal are paired in a `try { … } finally { … }`: register the guard, run the spawn-to-exit section inside `try`, and in `finally` call `cleanupDocker(dockerResult)` exactly once (make `cleanupDocker` idempotent if it is not already) and `process.removeListener("exit", exitGuard)`. The exit guard itself must stay registered for the abnormal-exit case (that is its purpose) — only the normal path must deterministically remove it. + +**Acceptance criteria.** +- A unit test (or integration test under `integration/`) asserts that after a successful Docker-path run completes, `process.listeners("exit")` does not contain the guard (count of exit listeners returns to its pre-run value). +- A test asserts the same when the awaited child exit rejects/throws (simulate with a stubbed `execResult`). +- `cleanupDocker` invoked twice on the same `dockerResult` is a no-op the second time, covered by a test. +- Existing run/E2E tests still pass. + + +## Imported-channel sends never dispatch: normalize channel keys #dev-ready + +**Context.** Channel routes are registered in `NodeWorkflowRuntime` keyed by the **bare** channel name from `channel -> …` lines. The send step matches a context by `this.workflowCtxStack[i].routes.has(step.channel)` (`src/runtime/kernel/node-workflow-runtime.ts:672`), where `step.channel` is the **verbatim token** left of `<-`. So a validated cross-module send `lib.topic <- "msg"` never matches the route registered as `topic` — the message is enqueued unrouted and silently dropped. `docs/inbox.md` ("Module scope" section) currently documents this as a known footgun. + +**Change.** At send time (or when registering routes — pick one canonical normalization point), strip the `alias.` prefix from the channel token after the validator has confirmed the alias/channel pair exists, so `lib.topic` and `topic` resolve to the same route key. The validator in `src/transpile/validate.ts` already proves the imported channel exists, so the runtime can safely compare bare names. Inbox audit files (`inbox/NNN-.txt`) and `INBOX_ENQUEUE` events should record the bare channel name. + +**Acceptance criteria.** +- Write the failing-today scenario as a test first, then make it pass: the **entry** module declares `channel topic -> handler` and imports `lib`; `lib` declares `channel topic`; the entry workflow sends `lib.topic <- "x"`. Today the send enqueues under the literal key `lib.topic`, never matches the route registered as `topic`, and is silently dropped. After the fix, assert `handler` is invoked with payload `"x"`. +- `INBOX_ENQUEUE` in `run_summary.jsonl` and the `inbox/NNN-*.txt` filename use the bare channel name; covered by assertions in the same test. +- `docs/inbox.md` "Module scope" paragraph is rewritten to describe the normalized behavior. + + +## Add an inbox dispatch iteration cap #dev-ready + +**Context.** `drainWorkflowQueue` in `src/runtime/kernel/node-workflow-runtime.ts` processes the in-memory channel queue with `while (cursor < queue.length)`; dispatched targets may send again, appending to the same queue. There is no iteration cap, so circular sends (A routes to B, B sends back to A's channel) loop until OOM. `docs/inbox.md` explicitly warns "Avoid unbounded circular sends" instead of the runtime enforcing a bound. + +**Change.** Add a hard cap on the number of messages drained per workflow frame. Default **1000**; overridable via env `JAIPH_INBOX_MAX_DISPATCH` (positive integer). On exceeding the cap, fail the owning workflow with a clear error, e.g. `E_INBOX_DISPATCH_LIMIT: drained 1000 messages without quiescing — likely a circular send (channel ""); raise JAIPH_INBOX_MAX_DISPATCH if intentional`. + +**Acceptance criteria.** +- Kernel/e2e test: a two-workflow circular send fails with the new error code instead of hanging; the error names the channel and the limit. +- Test that `JAIPH_INBOX_MAX_DISPATCH=5` triggers the cap after 5 messages. +- Normal multi-message fan-out below the cap is unaffected (existing inbox tests pass). +- `docs/inbox.md` ("Error semantics" and the circular-sends bullet) and `docs/cli.md` (env var list) document the cap and env override. + + +## Honor workflow-level `run.recover_limit` #dev-ready + +**Context.** A workflow body may open with a `config { … }` block that overrides `agent.*` and `run.*` keys. But `resolveRecoverLimit` (`src/runtime/kernel/node-workflow-runtime.ts:1387`) reads only `moduleMeta?.run?.recoverLimit ?? 10` — a workflow-level `run.recover_limit = 3` parses fine and is silently ignored. `docs/configuration.md` documents this exception, which is a trap: config that validates but does nothing. + +**Change.** Make `run … recover` resolve its limit through the same precedence as other run keys: **workflow-level config > module-level config > default 10**. Update `resolveRecoverLimit` to consult the active workflow's metadata scope before falling back to module metadata. Then delete the exception text from `docs/configuration.md` (three places: "Three ways to configure", "Run keys" table row, "Workflow-level config" rules) and from `docs/grammar.md` / `docs/jaiph-skill.md` if mentioned. + +**Acceptance criteria.** +- Test: a workflow with `config { run.recover_limit = 2 }` and a `run failing_script() recover (e) { … }` step retries exactly 2 times then fails (count attempts via a counter file written by the script). +- Test: a sibling workflow in the same module without its own config still uses the module-level value. +- Docs updated as described; `grep -rn "workflow-level run.recover_limit" docs/` returns nothing stale. + + +## Add `else` branch to `if` #dev-ready + +**Context.** `if var == "value" { … }` exists in workflows and rules, but there is no `else`. The documented workaround is `match`, which forces a wildcard arm and value-shaped bodies, or abusing `catch` blocks. This is the single biggest ergonomic gap agents hit when authoring workflows. Parser entry: `src/parse/` (the `if` handler in the `STATEMENT` dispatch table in `src/parse/workflow-brace.ts`); step validation: `src/transpile/validate-step.ts`; runtime: the `if` case in `src/runtime/kernel/node-workflow-runtime.ts`; formatter: `src/format/emit.ts`. + +**Change.** Support: + +```jaiph +if status == "ok" { + log "healthy" +} else { + logerr "unhealthy: ${status}" +} +``` + +Rules: `else` must appear on the same line as the closing `}` of the `if` block (`} else {`), takes a brace block of the same step forms allowed in the surrounding body (workflow vs rule constraints apply identically), no `else if` chaining in this task (a bare `else` containing a nested `if` is fine). `if`/`else` remains a statement (no value production). + +**Acceptance criteria.** +- txtar fixtures in `test-fixtures/compiler-txtar/valid.txt`: `if/else` in a workflow and in a rule compile. +- txtar fixtures in `parse-errors.txt`: `else` on its own line without `}`, `else` without a preceding `if`, and `else if (`chaining`)` each produce `E_PARSE` with a fix hint. +- Golden AST fixture + expected JSON for an `if/else` statement (`test-fixtures/golden-ast/`). +- Runtime e2e test: both branches execute correctly (true → then-block only, false → else-block only), in a workflow and in a rule. +- Rule-scope validation still rejects forbidden steps (e.g. `prompt`) inside an `else` block in a rule — covered by a txtar case. +- `jaiph format` is idempotent on `if/else` (formatter test), emitting canonical `} else {`. +- `docs/grammar.md` (`if` section + EBNF), `docs/language.md`, and `docs/jaiph-skill.md` updated (remove "no else" claims). + + +## Allow `catch` / `recover` on inline-script `run` steps #dev-ready + +**Context.** Named-ref calls support failure handling (`run deploy() catch (err) { … }`, `run deploy() recover (err) { … }`), but inline scripts do not: `` run `test -z "$(git status --porcelain)"`() catch (err) { … } `` fails with `E_PARSE unexpected content after anonymous inline script: 'catch (err) {'`. Authors are forced to declare a named `script` solely to attach failure handling to a one-liner. The grammar EBNF in `docs/grammar.md` shows `run_catch_stmt = "run" call_ref "catch" …` (call_ref only); the inline-script parse path rejects any trailing tokens after the closing `)`. + +**Change.** Extend the inline-script `run` parse path (single-backtick and fenced forms) to accept the same optional `catch (name) ` / `recover (name) ` suffixes as named-ref `run`, with identical semantics (catch = once, recover = retry loop honoring `run.recover_limit`, mutually exclusive). Runtime: inline scripts already execute through the same managed-subprocess path as named scripts, so the catch/recover machinery should be reusable. Keep the existing restriction that `run async` does not combine with inline scripts. + +**Acceptance criteria.** +- txtar `valid.txt` cases: inline script + `catch` block, inline script + `recover` block, in both workflow and rule bodies. +- Runtime e2e: a failing inline script's `catch` body runs once with the merged output bound; a failing inline script under `recover` retries until a counter-file-based repair makes it pass. +- `recover` + `catch` together on one inline step is rejected (same error as named refs) — txtar case. +- `docs/grammar.md` EBNF (`run_catch_stmt` / `run_recover_stmt` / `inline_script`) and the Inline Scripts restriction list updated; `docs/jaiph-skill.md` inline-script section updated (remove the "no catch/recover on inline scripts" caveat). + + +## Allow dot-notation subjects in `if` and `match` #dev-ready + +**Context.** Typed prompt captures expose fields via dot notation (`${r.verdict}`) in strings, but `if` and `match` subjects must be plain identifiers: `if r.verdict == "reject" { … }` fails with `E_PARSE invalid if syntax; expected: if …`. The workaround (`const verdict = "${r.verdict}"` then `if verdict == …`) is boilerplate on the most common typed-prompt pattern: ask for a verdict, branch on it. + +**Change.** Accept `IDENT.IDENT` as the subject of `if` and `match` statements/expressions when the base identifier is a typed prompt capture and the field exists in its `returns` schema — the same compile-time validation already implemented for `${var.field}` interpolation (see dot-notation validation in `src/transpile/`). Runtime resolves the field value exactly as interpolation does. Plain unknown `a.b` subjects (not a typed capture, or unknown field) get the existing dot-notation `E_VALIDATE` errors, not a parse error. + +**Acceptance criteria.** +- txtar `valid.txt`: `if r.verdict == "ok" { … }` and `const x = match r.verdict { … }` compile when `r` is a typed prompt capture with a `verdict` field. +- txtar `validate-errors.txt`: dot subject on a non-typed-capture variable and on an unknown field produce the same `E_VALIDATE` messages as the interpolation path. +- Runtime e2e (with `mock prompt` JSON): both `if` branches and `match` arms select correctly based on the field value. +- Golden AST fixture for an `if` with a dot-notation subject. +- `docs/grammar.md` (`if`, `match`, EBNF subject productions) and `docs/jaiph-skill.md` (control-flow bullet about rebinding dot fields) updated. + + +## Per-subcommand `-h` / `--help` #dev-ready + +**Context.** Only `jaiph compile -h` prints command usage; `jaiph run --help`, `jaiph test --help`, `jaiph format --help`, `jaiph install --help` are parsed as file paths or ignored tokens and produce confusing errors (`src/cli/index.ts` recognizes `-h`/`--help` only as the first token after `jaiph`). `docs/cli.md` ("Global options") documents this limitation instead of fixing it. + +**Change.** Every subcommand (`run`, `test`, `compile`, `format`, `init`, `install`, `use`) recognizes `-h` / `--help` anywhere in its argument list **before positional processing**, prints its own usage block (flags + one example) to stdout, and exits 0. Keep `jaiph --help` as the overview. Put each usage string next to its command implementation in `src/cli/commands/*.ts` so it stays in sync. + +**Acceptance criteria.** +- Integration test iterating all seven subcommands: `jaiph --help` and `jaiph -h` exit 0 and stdout contains the subcommand name and the word `Usage`. +- `jaiph run --help` no longer attempts to resolve `--help` as a file. +- `jaiph --help` and bare `jaiph` behavior unchanged (existing tests). +- `docs/cli.md` "Global options" paragraph rewritten to state per-command help exists. + + +## `jaiph test` discovery with zero tests should not fail #dev-ready + +**Context.** `jaiph test` (no args) and `jaiph test ` exit **1** with `jaiph test: no *.test.jh files found` when discovery matches nothing (`src/cli/commands/test.ts:25,43`). This forces every CI pipeline and agent loop to guard the call ("run jaiph test only if test files exist"), and the bootstrap skill doc has to carry a warning about it. + +**Change.** In **discovery mode** (no path, or a directory path), zero matches prints `jaiph test: no *.test.jh files found (nothing to do)` to stderr and exits **0**. Passing an explicit **file** path that does not exist or is not a `*.test.jh` file remains an error (exit 1) — a named target must exist. + +**Acceptance criteria.** +- Test: `jaiph test` in a workspace without any `*.test.jh` exits 0 and prints the notice. +- Test: `jaiph test ` where the dir exists but has no test files exits 0. +- Test: `jaiph test missing.test.jh` (nonexistent file) exits 1. +- Existing behavior for found-and-failing tests unchanged (exit non-zero). +- `docs/cli.md` and `docs/testing.md` updated; remove the "skip jaiph test if there are no test files" caveat from `docs/jaiph-skill.md` ("Your authoring loop" and the final commands block). + + +## Reject mixing `mock prompt { … }` with queued `mock prompt "…"` #dev-ready + +**Context.** In a `*.test.jh` test block, when a pattern-dispatch `mock prompt { … }` block is present, all queue-style `mock prompt "…"` / `mock prompt ` lines in the same block are **silently ignored** (`docs/testing.md` "Limitations" documents this). Silently ignoring authored mocks makes tests pass for the wrong reason. + +**Change.** Make the combination a compile-time error for the test file: when a single `test` block contains both a `mock prompt { … }` block and at least one queue-style `mock prompt` entry, fail with `E_PARSE` (or `E_VALIDATE`, matching how other test-block shape errors are reported) and a message like: `cannot mix "mock prompt { … }" with queued "mock prompt …" in one test block; choose one style`. Implementation likely lives where test blocks are parsed/validated (`parseTestBlock` and/or the test-file validation path; see `src/runtime/kernel/node-test-runner.ts` and the parser for test blocks). + +**Acceptance criteria.** +- txtar fixture (or parser unit test) with a `.test.jh` file mixing both styles in one block fails with the new message; the same styles in **separate** test blocks of one file still pass. +- `jaiph compile path/to/file.test.jh` surfaces the error (test files are validated when passed explicitly). +- `docs/testing.md`: replace the "Do not combine…ignored" limitation bullets with the new error behavior. + + +## Formatter must not strip quotes from top-level `const` string values #dev-ready + +**Context.** `jaiph format` rewrites a top-level `const x = ".jaiph/tmp/x.md"` to the unquoted bare-token form `const x = .jaiph/tmp/x.md` — but only when the value contains no spaces; values with spaces keep their quotes. The result is value-preserving and idempotent (verified), but the formatter silently changes the author's chosen delimiter and produces inconsistent output within one file (quoted and unquoted consts side by side, depending on whether the value happens to contain a space). A formatter should canonicalize to one stable form, not toggle forms based on value content. Reproduce: write a file with `const p = "some/path with space.md"` and `const q = ".jaiph/tmp/x.md"`, run `jaiph format` — `p` stays quoted, `q` loses its quotes. Top-level `const` emission lives in `src/format/emit.ts` (envDecls path); the parser is in `src/parser.ts` / `src/parse/`. + +**Change.** Canonical rule: a top-level `const` value written as a **double-quoted string** in the source is emitted **double-quoted**, always — regardless of spaces. Values written as **bare tokens** (e.g. `const MAX = 3`) stay bare. If the AST currently discards the was-quoted distinction, extend the env-decl AST node to retain it (and update golden AST fixtures accordingly). The same rule should hold for `"""…"""` values (already emitted verbatim). + +**Acceptance criteria.** +- Formatter unit test: a quoted no-space value (`const q = ".jaiph/tmp/x.md"`) survives `jaiph format` with quotes intact; a quoted value with spaces also survives; a bare numeric token stays bare. +- Idempotency test: formatting twice produces identical output for all three cases. +- `jaiph compile` accepts the formatted output and `${q}` interpolation yields the same value as before formatting (runtime or kernel test). +- Golden AST fixtures regenerated only if the AST shape changed, with the diff reviewed and explained in the commit message. +- Existing `.jh` files in the repo reformatted with the fixed formatter (`jaiph format` over `.jaiph/*.jh`, `examples/`, `e2e/` fixtures that are format-clean today) — committed alongside, so `--check` stays green. + + +## Error-message quality pass: async handles, Docker timeout, empty stderr #dev-ready + +**Context.** Three runtime errors give users nothing to act on: +1. `src/runtime/kernel/node-workflow-runtime.ts:110` — unknown async handle returns `error: "invalid handle"` with no handle id or hint. +2. `src/cli/commands/run.ts` (~line 190) — Docker timeout appends literally `E_TIMEOUT container execution exceeded timeout` with no duration or remedy. +3. `src/cli/shared/errors.ts:26` — `summarizeError()` falls back to `"Workflow execution failed."` when stderr is empty, hiding where to look next. + +**Change.** +1. → `invalid async handle "${handleId}" — the handle was never created or was already consumed`. +2. → `` `E_TIMEOUT container execution exceeded ${activeDockerConfig.timeoutSeconds}s — increase runtime.docker_timeout_seconds or JAIPH_DOCKER_TIMEOUT` `` (use the actual configured value). +3. → when stderr is empty and an exit code is known, `` `Workflow execution failed (exit ${code}) with no error output; inspect run_summary.jsonl and step artifacts under ${runDir}` `` (fall back to the old text only when neither code nor run dir is known). + +**Acceptance criteria.** +- Unit tests assert each new message shape (handle id present; timeout seconds value present; exit code and run dir present). +- No existing e2e expectation matches the old strings (`grep -rn "invalid handle" e2e/ src/` shows only the new form; update any expectations that asserted the old text). + + +## Lazy-load the Docker overlay script with an actionable error #dev-ready + +**Context.** `src/runtime/docker.ts:287` reads `overlay-run.sh` with `readFileSync` at **module load time**. Importing the docker module — which happens for every CLI invocation that might touch Docker — crashes with a raw ENOENT stack trace if the file is missing from the installation, even for commands that never use Docker. + +**Change.** Move the read into a function (`loadOverlayScript()`) called only where the script is written out (~line 301, `writeFileSync(scriptPath, OVERLAY_SCRIPT, …)`). Wrap the read in try/catch and rethrow as `E_CLI_SETUP: runtime/overlay-run.sh not found at — the Jaiph installation is incomplete; reinstall with "jaiph use "`. Cache the content after first successful read. + +**Acceptance criteria.** +- Unit test: importing the docker module does not read `overlay-run.sh` (e.g. temporarily rename the file in a sandboxed copy, import succeeds, calling the overlay path throws the `E_CLI_SETUP` message containing the path). +- Non-Docker commands (`jaiph compile`, `jaiph format`) work even when `overlay-run.sh` is absent — covered by a test or e2e case. +- Docker e2e flow unchanged when the file exists. + + +## Remove dead `formatDiagnosticLine` indirection in the stderr parser #dev-ready + +**Context.** `src/cli/run/stderr-handler.ts` threads a `formatDiagnosticLine: (line: string) => string` parameter through `handleLine` (line 49) and defines it as the identity function `(ln) => ln` (line 86) at the only call-site builder (`createStderrParser`, line 90). It never formats anything — pure dead indirection. + +**Change.** Delete the parameter from `handleLine` and the identity function from `createStderrParser`; use `line` directly in the `emitter.emit("stderr_line", …)` call (line 78). Update all `handleLine` call sites and any tests that pass the parameter. + +**Acceptance criteria.** +- `grep -rn "formatDiagnosticLine" src/` returns nothing. +- `npm test` passes; stderr passthrough behavior in run output is unchanged (existing integration tests cover this). + + +## Document the Docker env-var allowlist in sandboxing docs #dev-ready + +**Context.** `isEnvAllowed()` (`src/runtime/docker.ts:479`) forwards only environment variables matching `ENV_ALLOW_PREFIXES` (see the constant near that function — e.g. `JAIPH_`, agent/LLM-related prefixes) into the container, excluding `JAIPH_DOCKER_*`. `docs/sandboxing.md` does not mention this filtering, so users cannot tell why their custom env vars vanish inside sandboxed runs. + +**Change.** Add a "Environment forwarding" section to `docs/sandboxing.md`: list the exact allow prefixes and the `JAIPH_DOCKER_*` exclusion (read them from the constants in `src/runtime/docker.ts` — do not guess), state that all other host variables are **not** forwarded, and show the workaround (export inside a `script` body, or bake values into the image). Cross-link from `docs/configuration.md` ("Inspecting effective config at runtime") and `docs/cli.md` (Docker env var section). + +**Acceptance criteria.** +- `docs/sandboxing.md` contains the new section with the prefix list matching the source constants verbatim (reviewer check: diff the doc list against `ENV_ALLOW_PREFIXES` / `ENV_ALLOW_EXCLUDE_PREFIX` in `src/runtime/docker.ts`). +- The docs-parity workflow (`.jaiph/docs_parity.jh`), if run, raises no contradiction between the section and the implementation. +- Cross-links added in the two referenced docs. \ No newline at end of file From 471175649a7cd3351a1e2ad73b4954acfbe866ae Mon Sep 17 00:00:00 2001 From: Jakub Dzikowski Date: Wed, 10 Jun 2026 09:21:16 +0200 Subject: [PATCH 17/66] Workflows: dedupe helpers, recover-based CI loop, security review - Add .jaiph/lib_common.jh with shared exported scripts; dedupe architect_review and ensure_ci_passes (echo-based file writer with swapped arg order replaced by python3 (path, content) version). - ensure_ci_passes: replace unbounded recursive catch with a run ... recover loop bounded by run.recover_limit. - engineer: normalize classifier output (lowercase + regex match) before select_role; dedupe safety constraints into consts; cite QUEUE.md rule 7 verbatim in the implement prompt; drop dead script. - Add .jaiph/security_review.jh: diff-scoped review gated on HIGH findings, methodology adapted from anthropics/claude-code-security- review, with read-only worktree guard and report artifact. - Remove .jaiph/main.jh (engineer is invoked directly; also removes the "queue"-as-role bug) and scratch .jaiph/testing.jh.

Each prompt now opens with an instruction to read and follow `.jaiph/skills/documentation-writer/SKILL.md` **before doing anything else**; the skill is referenced by explicit path so both the Claude and Cursor backends can `Read` it directly without depending on agent-specific skill auto-discovery directories. The skill is vendored from `github/awesome-copilot` at `.jaiph/skills/documentation-writer/SKILL.md` (committed, not gitignored; the file header records the upstream URL, blob SHA, and copy date so it can be re-synced) — vendoring rather than `npx skills add` at runtime keeps docs runs offline-safe and reproducible. It supplies the **Diátaxis** framework's four document types (tutorial / how-to / reference / explanation), the clarify → outline → write workflow, and the four guiding principles (clarity, accuracy, user-centricity, consistency). The inline `role` const is slimmed to project-specific context the skill does not cover — TypeScript / Bash fluency for verifying docs against the implementation, `docs/architecture.md` as the single source of truth (do not trust existing docs blindly), and the constraint that navigation between docs pages is provided by the Jekyll template in `docs/_layouts/docs.html` (no manual "More Documentation" blocks). `jaiph compile .jaiph` and `jaiph format --check .jaiph/docs_parity.jh` stay green. - **Refactor — Replace the `parseBlockStatement` keyword cascade with a `STATEMENT` dispatch table:** `parseBlockStatement` in `src/parse/workflow-brace.ts` used to dispatch each statement form via a long ordered cascade of `startsWith` + regex tests (`"run async "` before `"run "`, `"prompt "` before bare assignment, etc.), so adding a new keyword meant finding the right slot in the cascade and any reordering risked changing which branch fired. The cascade is replaced by a `STATEMENT: Record` table keyed by the leading keyword: the dispatcher tokenizes the first identifier on the trimmed line, looks it up in the table, and invokes the matching handler — which returns a `{ step, nextIdx }` result, returns `null` to fall through, or calls `fail(...)` to abort. The current rows are `if`, `for`, `const`, `fail`, `wait`, `ensure`, `run`, `prompt`, `log`, `logerr`, `return`, and `match`; each handler (`tryParseIf`, `tryParseFor`, `tryParseConst`, `tryParseFail`, `tryParseWait`, `tryParseEnsure`, `tryParseRun`, `tryParsePrompt`, `tryParseLog`, `tryParseLogerr`, `tryParseReturn`, `tryParseStandaloneMatch`) carries the same regex / `startsWith` checks that used to live inline in the cascade — body shapes are unchanged. After dispatch, two non-keyword fallbacks fire in order: `trySend` (matches `channel <- rhs` via `matchSendOperator`) and `shellFallthrough` (everything else becomes a shell `exec` step). Assignment-shape error guards (`name = prompt …`, `name = run …` without `const`) live in a separate `applyAssignmentGuards(c)` helper that runs before the table lookup and either calls `fail(...)` or returns; the `forRule` rejection of `prompt …` inside rules also moves here. The shared per-line context (`filePath`, `lines`, `idx`, `innerRaw`, `inner`, `innerNo`, `trivia`, `forRule`, `opts`) is now a `BlockCtx` record threaded into every handler, so handlers take one argument instead of nine. Surface syntax is unchanged, every existing parse-error message / line / col is preserved, and the full golden corpus passes byte-for-byte. New tests pin the invariants: `src/parse/parse-error-snapshot.test.ts` walks every `=== name` block in `test-fixtures/compiler-txtar/parse-errors.txt`, parses each via `loadModuleGraph`, and asserts the captured `{ file, line, col, code, message }` matches the snapshot stored at `test-fixtures/compiler-txtar/parse-errors-snapshot.json` bit-for-bit — any drift in parser error wording or location fails the test (refreshable with `UPDATE_SNAPSHOTS=1` only after confirming the change is intentional). `src/parse/parse-synthetic-keyword.test.ts` pins the two-file extension contract: it patches `STATEMENT` at runtime with a synthetic `zzznoop` handler, asserts `parseBlockStatement` dispatches to it, asserts the same input falls through to the shell handler when the row is absent, and greps `src/parse/workflow-brace.ts` and `src/parse/core.ts` to confirm the `STATEMENT` table and the `JAIPH_KEYWORDS` reserved set each live in exactly one file. Adding a new top-level keyword is now a two-place change: one row in `STATEMENT` (`workflow-brace.ts`) and one entry in `JAIPH_KEYWORDS` (`core.ts`). `BlockCtx`, `BlockResult`, `BlockHandler`, and `STATEMENT` are exported so external test files can stage synthetic handlers without forking the parser. Out of scope: the wider tokenizer rewrite (the seven independent `inDoubleQuote` / `inTripleQuote` / `braceDepth` scanners across `src/parse/`, the line-walking `{ step, nextIdx }` contract, and the per-handler regex bodies are deferred — this refactor only changes the *dispatch shape* inside `parseBlockStatement`, not the scanning underneath). User-visible contracts — surface syntax, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Keyword dispatch table** paragraph), `docs/contributing.md` (new **Statement-dispatch-table shape** row in the test-layer table), and `docs/grammar.md` (extended the EBNF aside to name the `STATEMENT` table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 1 AC3 / AC4 / AC5 (the full tokenizer rewrite remains future work). - **Refactor — Unify `catch` / `recover` parsing into a single attached-block routine sharing the top-level statement parser:** `src/parse/steps.ts` used to contain three near-identical 100+ line functions — `parseEnsureStep`, `parseRunCatchStep`, and `parseRunRecoverStep` — that parsed the same syntactic shape (` (binding) { body } | single-stmt`) and differed only in which host step they decorated (`ensure` vs `run`) and the literal keyword (`catch` vs `recover`). Their body parser, `parseCatchStatement` (~280 lines), was a stripped-down copy of `parseBlockStatement` that recognized only a fixed subset of statement forms (e.g. a `for … in …` head fell through to a shell command) and diverged in subtle ways — the same fix had to land in two places, and divergence wasn't always caught by tests. All four functions and every helper that existed only to serve them are deleted from `src/parse/steps.ts`. The file drops from **757 → ~140 lines**. The new shape: one entry point `parseAttachedBlock(filePath, lines, idx, innerNo, innerRaw, keyword: "catch" | "recover", textAfterKeyword, trivia)` in `src/parse/steps.ts` parses the bindings (`()` — exactly one identifier, with the same too-many / too-few / non-identifier errors as before) and dispatches on the body shape: a `{` at end of host line walks the existing brace-block scanner and delegates each body statement to `parseBraceBlockBody`, an inline `{ stmt[; stmt]* }` splits on `;` via the shared `splitStatementsOnSemicolons` and dispatches each fragment, and a bare single statement is parsed in-place. In all three cases the body statements run through the **same** `parseBlockStatement` (`src/parse/workflow-brace.ts`) that handles top-level statements — there is no mini parser for catch/recover bodies anymore. The host side moves to one helper `parseRunOrEnsure(filePath, lines, idx, …, host: "run" | "ensure", hostBody, isAsync, captureName, trivia)` in `src/parse/workflow-brace.ts`, called from `parseBlockStatement`'s three call sites (`ensure ref(...)`, `run ref(...)`, `run async ref(...)`). It scans `hostBody` once for a trailing ` recover` (run-only) then ` catch ` segment, parses the host call before the keyword, and delegates the attached clause to `parseAttachedBlock`. "Is this statement allowed inside a catch/recover body?" is now a validator concern — `WORKFLOW_SCOPE` and `RULE_SCOPE` in `validate-step.ts` already gate which step types are accepted in each scope, so rules still reject unstructured shell inside `catch` / `recover` bodies; workflows still accept it. New tests in `src/parse/parse-attached-block.test.ts` pin the invariants: AC1 — an LoC test caps `src/parse/steps.ts` at **≤200 lines** and a grep test fails if any function named `parse(Run)?(Catch|Recover|EnsureStep)` reappears; AC2 — a `for line in items { log "$line" }` statement (a `parseBlockStatement`-only form historically) is parsed as a `for_lines` step at the top level, inside `ensure check() catch (e) { … }`, and inside `run target() recover(e) { … }` — proving `parseBlockStatement` is the single entry point for any statement inside a catch / recover body and there is no separate mini parser; AC3 — a 10-case error-snapshot battery asserts every existing parse error message and column (bindings missing, too many bindings, empty inline / multiline block, unterminated multiline block, missing-paren for both `catch` and `recover` on both `run` and `ensure` hosts) is preserved bit-for-bit. The full parser / validator / emitter golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, `parse-steps.test.ts`, `parse-bare-call.test.ts`, `parse-run-async.test.ts`, and the txtar / golden-AST fixtures) passes byte-for-byte (AC4). User-visible contracts — surface syntax for `catch` / `recover`, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Out of scope: the wider tokenizer rewrite (Refactor 1, deferred); validator changes beyond the per-keyword scope rules that already exist. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Unified `run` / `ensure` host parsing** paragraph), `docs/contributing.md` (new **Attached-block parser shape** row in the test-layer table), and `docs/grammar.md` (replaced the stale `parseCatchStatement` reference in the EBNF aside with a note that `parseAttachedBlock` delegates to `parseBlockStatement`). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 2. - **Refactor — Decouple the validator from runtime semantics:** `src/transpile/validate.ts` (now `validate-step.ts`) used to `import { tripleQuotedRawForRuntime } from "../runtime/orchestration-text"` so it could compute "what the runtime will see" when checking the content of a triple-quoted `match`-arm body. That was a one-way dependency from compile-time on runtime semantics — a layering inversion that would have kept biting as the runtime grew more such helpers. The canonicalization helper moves into the parser layer as `canonicalizeTripleQuotedString` in `src/parse/triple-quote.ts` (same algorithm: validate the outer `"…"` shape, unescape DSL-quoted inner with `\"` → `"` and `\\` → `\`, then re-wrap via `tripleQuoteBodyToRaw(dedentCommonLeadingWhitespace(inner))`). Both the validator (`validate-step.ts`'s `validateMatchExpr`) and the runtime (`src/runtime/kernel/node-workflow-runtime.ts`'s match-arm dispatch in `runMatchExpr`) now import that helper from `src/parse/`; the wrapper file `src/runtime/orchestration-text.ts` is deleted. New tests pin the invariants: `src/transpile/no-runtime-imports.test.ts` (AC1) greps every non-test `*.ts` under `src/transpile/` and fails if any `from "…/runtime/…"` import reappears, so compile-time code can no longer reach into runtime semantics; `src/parse/canonicalize-triple-quoted.test.ts` (AC2) parses every `.jh` under `test-fixtures/` and `examples/`, collects every triple-quoted `match`-arm body across workflow / rule step trees, and asserts `canonicalizeTripleQuotedString(body) === legacyTripleQuotedRawForRuntime(body)` bit-for-bit (the legacy implementation is inlined in the test as the parity baseline). Existing `validate-string.test.ts` cases and the golden corpus pass unchanged (AC3); `npm run build` passes with zero TypeScript strict-mode errors (AC4). User-visible contracts — CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming, and the full golden corpus — are unchanged byte-for-byte. Out of scope: rethinking what the canonical form *is* — this refactor only relocates the helper. Docs updated in `docs/architecture.md` (new **No compile-time → runtime imports** bullet under **Validator**; extended **Parser** bullet to document `canonicalizeTripleQuotedString` alongside `parseTripleQuoteBlock`) and `docs/contributing.md` (new **Compile-time / runtime layering** row in the test-layer table).

This was inconsistent with the other three call types (root entry, same-module `run`, cross-module `ensure`) and bit `.jaiph/ensure_ci_passes.jh` in particular: that module declares `agent.backend = "cursor"`, but when `engineer.jh` (backend `claude`) called `run ci.ensure_ci_passes()`, the CI-fix prompts silently ran on `claude`. A module's `config` should describe how *that* module's workflows run, regardless of who called them. `NodeWorkflowRuntime` now layers the callee's module-level metadata then the callee's workflow-level metadata on top of the caller's effective env when entering a cross-module `run` — same mechanics as the root-entry path, respecting `${NAME}_LOCKED` env flags (environment still always wins). The caller's scope is restored exactly when the call returns, so sibling isolation still holds. New / updated tests: `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` adds three cases — (a) module A (`agent.default_model = "model-a"`) runs `run b.show()` where module B sets `agent.default_model = "model-b"` and `show` logs the model: callee logs `model-b`, the next step in A's workflow logs `model-a` again (scope restored); (b) callee workflow-level config wins over callee module-level config on the cross-module path; (c) with `JAIPH_AGENT_MODEL` exported in the environment (locked), the callee's config does NOT override it. `e2e/tests/86_metadata_scope_nested.sh` and `e2e/tests/87_workflow_config.sh` are updated where they previously asserted the old (ignore) behavior — the nested call now sees the callee's backend during execution and the caller's backend is restored after. The now-stale `NOTE` comment at the top of `.jaiph/ensure_ci_passes.jh` (which warned that cross-module callers' config would win) is removed. Docs updated in `docs/configuration.md` ("Scoping across nested calls" table — the cross-module row no longer says the callee's config is ignored; "Module-level config" paragraph rewritten to describe nested `run` as same- *or* cross-module and to flag same-module `ensure` as the one remaining caller's-scope-as-is case). - **Tooling — Documentation prompts follow a vendored Diátaxis skill:** The three prompts in `.jaiph/docs_parity.jh` (`update_from_task`, `docs_page`, `docs_overview`) used to inline the same ad-hoc "expert technical writer" `role` const and repeat its guiding principles in prose. Each prompt now opens with an instruction to read and follow `.jaiph/skills/documentation-writer/SKILL.md` **before doing anything else**; the skill is referenced by explicit path so both the Claude and Cursor backends can `Read` it directly without depending on agent-specific skill auto-discovery directories. The skill is vendored from `github/awesome-copilot` at `.jaiph/skills/documentation-writer/SKILL.md` (committed, not gitignored; the file header records the upstream URL, blob SHA, and copy date so it can be re-synced) — vendoring rather than `npx skills add` at runtime keeps docs runs offline-safe and reproducible. It supplies the **Diátaxis** framework's four document types (tutorial / how-to / reference / explanation), the clarify → outline → write workflow, and the four guiding principles (clarity, accuracy, user-centricity, consistency). The inline `role` const is slimmed to project-specific context the skill does not cover — TypeScript / Bash fluency for verifying docs against the implementation, `docs/architecture.md` as the single source of truth (do not trust existing docs blindly), and the constraint that navigation between docs pages is provided by the Jekyll template in `docs/_layouts/docs.html` (no manual "More Documentation" blocks). `jaiph compile .jaiph` and `jaiph format --check .jaiph/docs_parity.jh` stay green. - **Refactor — Replace the `parseBlockStatement` keyword cascade with a `STATEMENT` dispatch table:** `parseBlockStatement` in `src/parse/workflow-brace.ts` used to dispatch each statement form via a long ordered cascade of `startsWith` + regex tests (`"run async "` before `"run "`, `"prompt "` before bare assignment, etc.), so adding a new keyword meant finding the right slot in the cascade and any reordering risked changing which branch fired. The cascade is replaced by a `STATEMENT: Record` table keyed by the leading keyword: the dispatcher tokenizes the first identifier on the trimmed line, looks it up in the table, and invokes the matching handler — which returns a `{ step, nextIdx }` result, returns `null` to fall through, or calls `fail(...)` to abort. The current rows are `if`, `for`, `const`, `fail`, `wait`, `ensure`, `run`, `prompt`, `log`, `logerr`, `return`, and `match`; each handler (`tryParseIf`, `tryParseFor`, `tryParseConst`, `tryParseFail`, `tryParseWait`, `tryParseEnsure`, `tryParseRun`, `tryParsePrompt`, `tryParseLog`, `tryParseLogerr`, `tryParseReturn`, `tryParseStandaloneMatch`) carries the same regex / `startsWith` checks that used to live inline in the cascade — body shapes are unchanged. After dispatch, two non-keyword fallbacks fire in order: `trySend` (matches `channel <- rhs` via `matchSendOperator`) and `shellFallthrough` (everything else becomes a shell `exec` step). Assignment-shape error guards (`name = prompt …`, `name = run …` without `const`) live in a separate `applyAssignmentGuards(c)` helper that runs before the table lookup and either calls `fail(...)` or returns; the `forRule` rejection of `prompt …` inside rules also moves here. The shared per-line context (`filePath`, `lines`, `idx`, `innerRaw`, `inner`, `innerNo`, `trivia`, `forRule`, `opts`) is now a `BlockCtx` record threaded into every handler, so handlers take one argument instead of nine. Surface syntax is unchanged, every existing parse-error message / line / col is preserved, and the full golden corpus passes byte-for-byte. New tests pin the invariants: `src/parse/parse-error-snapshot.test.ts` walks every `=== name` block in `test-fixtures/compiler-txtar/parse-errors.txt`, parses each via `loadModuleGraph`, and asserts the captured `{ file, line, col, code, message }` matches the snapshot stored at `test-fixtures/compiler-txtar/parse-errors-snapshot.json` bit-for-bit — any drift in parser error wording or location fails the test (refreshable with `UPDATE_SNAPSHOTS=1` only after confirming the change is intentional). `src/parse/parse-synthetic-keyword.test.ts` pins the two-file extension contract: it patches `STATEMENT` at runtime with a synthetic `zzznoop` handler, asserts `parseBlockStatement` dispatches to it, asserts the same input falls through to the shell handler when the row is absent, and greps `src/parse/workflow-brace.ts` and `src/parse/core.ts` to confirm the `STATEMENT` table and the `JAIPH_KEYWORDS` reserved set each live in exactly one file. Adding a new top-level keyword is now a two-place change: one row in `STATEMENT` (`workflow-brace.ts`) and one entry in `JAIPH_KEYWORDS` (`core.ts`). `BlockCtx`, `BlockResult`, `BlockHandler`, and `STATEMENT` are exported so external test files can stage synthetic handlers without forking the parser. Out of scope: the wider tokenizer rewrite (the seven independent `inDoubleQuote` / `inTripleQuote` / `braceDepth` scanners across `src/parse/`, the line-walking `{ step, nextIdx }` contract, and the per-handler regex bodies are deferred — this refactor only changes the *dispatch shape* inside `parseBlockStatement`, not the scanning underneath). User-visible contracts — surface syntax, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Keyword dispatch table** paragraph), `docs/contributing.md` (new **Statement-dispatch-table shape** row in the test-layer table), and `docs/grammar.md` (extended the EBNF aside to name the `STATEMENT` table). Implements `design/2026-05-15-parser-compiler-simplification.md` § Refactor 1 AC3 / AC4 / AC5 (the full tokenizer rewrite remains future work). - **Refactor — Unify `catch` / `recover` parsing into a single attached-block routine sharing the top-level statement parser:** `src/parse/steps.ts` used to contain three near-identical 100+ line functions — `parseEnsureStep`, `parseRunCatchStep`, and `parseRunRecoverStep` — that parsed the same syntactic shape (` (binding) { body } | single-stmt`) and differed only in which host step they decorated (`ensure` vs `run`) and the literal keyword (`catch` vs `recover`). Their body parser, `parseCatchStatement` (~280 lines), was a stripped-down copy of `parseBlockStatement` that recognized only a fixed subset of statement forms (e.g. a `for … in …` head fell through to a shell command) and diverged in subtle ways — the same fix had to land in two places, and divergence wasn't always caught by tests. All four functions and every helper that existed only to serve them are deleted from `src/parse/steps.ts`. The file drops from **757 → ~140 lines**. The new shape: one entry point `parseAttachedBlock(filePath, lines, idx, innerNo, innerRaw, keyword: "catch" | "recover", textAfterKeyword, trivia)` in `src/parse/steps.ts` parses the bindings (`()` — exactly one identifier, with the same too-many / too-few / non-identifier errors as before) and dispatches on the body shape: a `{` at end of host line walks the existing brace-block scanner and delegates each body statement to `parseBraceBlockBody`, an inline `{ stmt[; stmt]* }` splits on `;` via the shared `splitStatementsOnSemicolons` and dispatches each fragment, and a bare single statement is parsed in-place. In all three cases the body statements run through the **same** `parseBlockStatement` (`src/parse/workflow-brace.ts`) that handles top-level statements — there is no mini parser for catch/recover bodies anymore. The host side moves to one helper `parseRunOrEnsure(filePath, lines, idx, …, host: "run" | "ensure", hostBody, isAsync, captureName, trivia)` in `src/parse/workflow-brace.ts`, called from `parseBlockStatement`'s three call sites (`ensure ref(...)`, `run ref(...)`, `run async ref(...)`). It scans `hostBody` once for a trailing ` recover` (run-only) then ` catch ` segment, parses the host call before the keyword, and delegates the attached clause to `parseAttachedBlock`. "Is this statement allowed inside a catch/recover body?" is now a validator concern — `WORKFLOW_SCOPE` and `RULE_SCOPE` in `validate-step.ts` already gate which step types are accepted in each scope, so rules still reject unstructured shell inside `catch` / `recover` bodies; workflows still accept it. New tests in `src/parse/parse-attached-block.test.ts` pin the invariants: AC1 — an LoC test caps `src/parse/steps.ts` at **≤200 lines** and a grep test fails if any function named `parse(Run)?(Catch|Recover|EnsureStep)` reappears; AC2 — a `for line in items { log "$line" }` statement (a `parseBlockStatement`-only form historically) is parsed as a `for_lines` step at the top level, inside `ensure check() catch (e) { … }`, and inside `run target() recover(e) { … }` — proving `parseBlockStatement` is the single entry point for any statement inside a catch / recover body and there is no separate mini parser; AC3 — a 10-case error-snapshot battery asserts every existing parse error message and column (bindings missing, too many bindings, empty inline / multiline block, unterminated multiline block, missing-paren for both `catch` and `recover` on both `run` and `ensure` hosts) is preserved bit-for-bit. The full parser / validator / emitter golden corpus (`src/transpile/compiler-golden.test.ts`, `src/transpile/compiler-edge.acceptance.test.ts`, `parse-steps.test.ts`, `parse-bare-call.test.ts`, `parse-run-async.test.ts`, and the txtar / golden-AST fixtures) passes byte-for-byte (AC4). User-visible contracts — surface syntax for `catch` / `recover`, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Out of scope: the wider tokenizer rewrite (Refactor 1, deferred); validator changes beyond the per-keyword scope rules that already exist. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Unified `run` / `ensure` host parsing** paragraph), `docs/contributing.md` (new **Attached-block parser shape** row in the test-layer table), and `docs/grammar.md` (replaced the stale `parseCatchStatement` reference in the EBNF aside with a note that `parseAttachedBlock` delegates to `parseBlockStatement`).

Any throw between registration and removal (stream wiring, the awaited child exit, buffer draining) left the listener on the process for the rest of its lifetime and re-invoked cleanupDocker on an already-cleaned container at exit. Introduce withDockerExitGuard in src/runtime/docker.ts: it registers the guard, runs the body inside try, and in finally — on both normal return and on throw — removes the listener and calls cleanupDocker exactly once. The guard itself stays registered for the abnormal-exit case (that is its purpose). cleanupDocker is already idempotent via the cleaned flag; its JSDoc now states that contract explicitly. New tests pin the invariants: cleanupDocker called twice is a no-op the second time, process.listeners("exit") returns to its pre-run value after a successful body, the same holds when the body throws, and no listener is registered when dockerResult is undefined.

The matching `process.removeListener("exit", exitGuard)` only ran inside the `if (dockerResult)` block *after* `await waitForRunExit(...)` resolved normally — so if anything between registration and removal threw (stream wiring, the awaited child exit, buffer draining), the listener stayed on the `process` object for the rest of the host CLI's lifetime and `cleanupDocker` would fire again at process exit on an already-cleaned container, also fattening the `exit`-listener list across nested or repeated runs. Registration and removal are now paired in a `try { … } finally { … }` block via a new helper `withDockerExitGuard(dockerResult, body)` exported from `src/runtime/docker.ts`. The helper registers the guard, runs the spawn-to-exit body inside `try`, and in `finally` — on both normal return *and* on throw — removes the listener and calls `cleanupDocker(dockerResult)`. The guard itself stays registered for the abnormal-exit case (that is its purpose); only the normal and thrown-body paths now deterministically remove it. When `dockerResult` is `undefined` (non-Docker run), no listener is registered at all. `cleanupDocker` was already idempotent through the `cleaned` flag on `DockerSpawnResult` (so both the finally path and any surviving guard / signal handler can call it without double-`rmSync` warnings); its JSDoc now states that contract explicitly because the exit-guard + finally pairing relies on it. New tests in `src/runtime/docker.test.ts` pin the invariants: (a) `cleanupDocker` invoked twice on the same `DockerSpawnResult` is a no-op the second time — sentinel files recreated under the overlay tempdir and sandbox tempdir after the first call survive the second call, and the cleared timeout timer never fires; (b) after a successful `withDockerExitGuard` body, `process.listenerCount("exit")` returns to its pre-run value and no new listener identity remains in `process.listeners("exit")`; (c) the same holds when the body throws — `await assert.rejects(...)` confirms the listener is still removed and `cleanupDocker` ran exactly once; (d) when `dockerResult` is `undefined`, the helper registers no listener and just returns the body's value. Existing E2E / run tests pass unchanged. Docs updated in `docs/sandboxing.md` (extended the **Signal-safe cleanup** paragraph under **Runtime behavior** to describe the `withDockerExitGuard` try/finally pairing, the abnormal-exit role of the guard, the no-op behavior for non-Docker runs, and `cleanupDocker`'s idempotency contract). - **Fix — Cross-module `run` applies the callee module's config:** Previously, when a workflow in module A reached a callee in module B via `run alias.workflow()`, both module B's module-level `config { … }` and the callee workflow's `config { … }` block were silently ignored — the caller's effective env carried through as-is. This was inconsistent with the other three call types (root entry, same-module `run`, cross-module `ensure`) and bit `.jaiph/ensure_ci_passes.jh` in particular: that module declares `agent.backend = "cursor"`, but when `engineer.jh` (backend `claude`) called `run ci.ensure_ci_passes()`, the CI-fix prompts silently ran on `claude`. A module's `config` should describe how *that* module's workflows run, regardless of who called them. `NodeWorkflowRuntime` now layers the callee's module-level metadata then the callee's workflow-level metadata on top of the caller's effective env when entering a cross-module `run` — same mechanics as the root-entry path, respecting `${NAME}_LOCKED` env flags (environment still always wins). The caller's scope is restored exactly when the call returns, so sibling isolation still holds. New / updated tests: `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` adds three cases — (a) module A (`agent.default_model = "model-a"`) runs `run b.show()` where module B sets `agent.default_model = "model-b"` and `show` logs the model: callee logs `model-b`, the next step in A's workflow logs `model-a` again (scope restored); (b) callee workflow-level config wins over callee module-level config on the cross-module path; (c) with `JAIPH_AGENT_MODEL` exported in the environment (locked), the callee's config does NOT override it. `e2e/tests/86_metadata_scope_nested.sh` and `e2e/tests/87_workflow_config.sh` are updated where they previously asserted the old (ignore) behavior — the nested call now sees the callee's backend during execution and the caller's backend is restored after. The now-stale `NOTE` comment at the top of `.jaiph/ensure_ci_passes.jh` (which warned that cross-module callers' config would win) is removed. Docs updated in `docs/configuration.md` ("Scoping across nested calls" table — the cross-module row no longer says the callee's config is ignored; "Module-level config" paragraph rewritten to describe nested `run` as same- *or* cross-module and to flag same-module `ensure` as the one remaining caller's-scope-as-is case). - **Tooling — Documentation prompts follow a vendored Diátaxis skill:** The three prompts in `.jaiph/docs_parity.jh` (`update_from_task`, `docs_page`, `docs_overview`) used to inline the same ad-hoc "expert technical writer" `role` const and repeat its guiding principles in prose. Each prompt now opens with an instruction to read and follow `.jaiph/skills/documentation-writer/SKILL.md` **before doing anything else**; the skill is referenced by explicit path so both the Claude and Cursor backends can `Read` it directly without depending on agent-specific skill auto-discovery directories. The skill is vendored from `github/awesome-copilot` at `.jaiph/skills/documentation-writer/SKILL.md` (committed, not gitignored; the file header records the upstream URL, blob SHA, and copy date so it can be re-synced) — vendoring rather than `npx skills add` at runtime keeps docs runs offline-safe and reproducible. It supplies the **Diátaxis** framework's four document types (tutorial / how-to / reference / explanation), the clarify → outline → write workflow, and the four guiding principles (clarity, accuracy, user-centricity, consistency). The inline `role` const is slimmed to project-specific context the skill does not cover — TypeScript / Bash fluency for verifying docs against the implementation, `docs/architecture.md` as the single source of truth (do not trust existing docs blindly), and the constraint that navigation between docs pages is provided by the Jekyll template in `docs/_layouts/docs.html` (no manual "More Documentation" blocks). `jaiph compile .jaiph` and `jaiph format --check .jaiph/docs_parity.jh` stay green. - **Refactor — Replace the `parseBlockStatement` keyword cascade with a `STATEMENT` dispatch table:** `parseBlockStatement` in `src/parse/workflow-brace.ts` used to dispatch each statement form via a long ordered cascade of `startsWith` + regex tests (`"run async "` before `"run "`, `"prompt "` before bare assignment, etc.), so adding a new keyword meant finding the right slot in the cascade and any reordering risked changing which branch fired. The cascade is replaced by a `STATEMENT: Record` table keyed by the leading keyword: the dispatcher tokenizes the first identifier on the trimmed line, looks it up in the table, and invokes the matching handler — which returns a `{ step, nextIdx }` result, returns `null` to fall through, or calls `fail(...)` to abort. The current rows are `if`, `for`, `const`, `fail`, `wait`, `ensure`, `run`, `prompt`, `log`, `logerr`, `return`, and `match`; each handler (`tryParseIf`, `tryParseFor`, `tryParseConst`, `tryParseFail`, `tryParseWait`, `tryParseEnsure`, `tryParseRun`, `tryParsePrompt`, `tryParseLog`, `tryParseLogerr`, `tryParseReturn`, `tryParseStandaloneMatch`) carries the same regex / `startsWith` checks that used to live inline in the cascade — body shapes are unchanged. After dispatch, two non-keyword fallbacks fire in order: `trySend` (matches `channel <- rhs` via `matchSendOperator`) and `shellFallthrough` (everything else becomes a shell `exec` step). Assignment-shape error guards (`name = prompt …`, `name = run …` without `const`) live in a separate `applyAssignmentGuards(c)` helper that runs before the table lookup and either calls `fail(...)` or returns; the `forRule` rejection of `prompt …` inside rules also moves here. The shared per-line context (`filePath`, `lines`, `idx`, `innerRaw`, `inner`, `innerNo`, `trivia`, `forRule`, `opts`) is now a `BlockCtx` record threaded into every handler, so handlers take one argument instead of nine. Surface syntax is unchanged, every existing parse-error message / line / col is preserved, and the full golden corpus passes byte-for-byte. New tests pin the invariants: `src/parse/parse-error-snapshot.test.ts` walks every `=== name` block in `test-fixtures/compiler-txtar/parse-errors.txt`, parses each via `loadModuleGraph`, and asserts the captured `{ file, line, col, code, message }` matches the snapshot stored at `test-fixtures/compiler-txtar/parse-errors-snapshot.json` bit-for-bit — any drift in parser error wording or location fails the test (refreshable with `UPDATE_SNAPSHOTS=1` only after confirming the change is intentional). `src/parse/parse-synthetic-keyword.test.ts` pins the two-file extension contract: it patches `STATEMENT` at runtime with a synthetic `zzznoop` handler, asserts `parseBlockStatement` dispatches to it, asserts the same input falls through to the shell handler when the row is absent, and greps `src/parse/workflow-brace.ts` and `src/parse/core.ts` to confirm the `STATEMENT` table and the `JAIPH_KEYWORDS` reserved set each live in exactly one file. Adding a new top-level keyword is now a two-place change: one row in `STATEMENT` (`workflow-brace.ts`) and one entry in `JAIPH_KEYWORDS` (`core.ts`). `BlockCtx`, `BlockResult`, `BlockHandler`, and `STATEMENT` are exported so external test files can stage synthetic handlers without forking the parser. Out of scope: the wider tokenizer rewrite (the seven independent `inDoubleQuote` / `inTripleQuote` / `braceDepth` scanners across `src/parse/`, the line-walking `{ step, nextIdx }` contract, and the per-handler regex bodies are deferred — this refactor only changes the *dispatch shape* inside `parseBlockStatement`, not the scanning underneath). User-visible contracts — surface syntax, CLI behavior, `jaiph format` round-trip, run artifacts, banner, hooks, exit codes, `__JAIPH_EVENT__` streaming — are unchanged. Docs updated in `docs/architecture.md` (extended **Parser** bullet with a new **Keyword dispatch table** paragraph), `docs/contributing.md` (new **Statement-dispatch-table shape** row in the test-layer table), and `docs/grammar.md` (extended the EBNF aside to name the `STATEMENT` table).

So a validated cross-module send like `lib.topic <- "msg"` never matched the route registered as `topic` — the message was enqueued unrouted and silently dropped. `docs/inbox.md` previously documented this as a known footgun ("Module scope" paragraph) and steered users to bare-channel sends from the entry module. The send step in `node-workflow-runtime.ts` now normalizes `step.channel` once, at send time: after the validator (`validateChannelRef` in `src/transpile/validate.ts`) has already proven that an `alias.name` token refers to an existing imported channel, the runtime strips the `alias.` prefix and uses the bare name as `channelKey` for both the `routes.has(channelKey)` walk up the workflow stack and the `InboxMsg.channel` field. `lib.topic <-` and a bare `topic <-` therefore resolve to the same route key. The `INBOX_ENQUEUE` record in `run_summary.jsonl` carries the bare channel name; the audit copy is written to `inbox/NNN-.txt`. New E2E coverage in `e2e/tests/91_inbox_dispatch.sh` ("Imported channel send: lib.topic normalizes to topic for routing") writes the failing-today scenario as a test first — entry module declares `channel topic -> handler` and imports `lib`, `lib` declares `channel topic`, the entry workflow sends `lib.topic <- "x"` — then asserts `handler` is invoked with payload `"x"`, the inbox audit file is `inbox/001-topic.txt` containing `x`, and the `INBOX_ENQUEUE` line in `run_summary.jsonl` records `channel: "topic"` (bare, alias prefix stripped). Docs updated in `docs/inbox.md` — the "Module scope" paragraph under [Who registers routes and who drains](docs/inbox.md#who-registers-routes-and-who-drains) is rewritten to describe the normalized behavior (and references `validateChannelRef` as the guarantee that any `alias.` prefix the runtime strips already names a real imported channel), the imported-channel bullet under **Send operator** drops the "literal token" caveat, and the [Send operator](docs/inbox.md#send-operator--channel_ref-rhs) paragraph clarifies that `sendChannel` is the bare channel name used for both the route lookup and the audit filename. - **Fix — Docker-run path no longer leaks the `process.on("exit")` cleanup guard:** In `src/cli/commands/run.ts` (`runWorkflow`), when `spawnExec` returned a `dockerResult`, an `exitGuard` callback was registered with `process.on("exit", exitGuard)` so that, if the host CLI crashed before the run finished, `cleanupDocker(dockerResult)` would still tear down the copy-mode sandbox directory and clear the timeout timer. The matching `process.removeListener("exit", exitGuard)` only ran inside the `if (dockerResult)` block *after* `await waitForRunExit(...)` resolved normally — so if anything between registration and removal threw (stream wiring, the awaited child exit, buffer draining), the listener stayed on the `process` object for the rest of the host CLI's lifetime and `cleanupDocker` would fire again at process exit on an already-cleaned container, also fattening the `exit`-listener list across nested or repeated runs. Registration and removal are now paired in a `try { … } finally { … }` block via a new helper `withDockerExitGuard(dockerResult, body)` exported from `src/runtime/docker.ts`. The helper registers the guard, runs the spawn-to-exit body inside `try`, and in `finally` — on both normal return *and* on throw — removes the listener and calls `cleanupDocker(dockerResult)`. The guard itself stays registered for the abnormal-exit case (that is its purpose); only the normal and thrown-body paths now deterministically remove it. When `dockerResult` is `undefined` (non-Docker run), no listener is registered at all. `cleanupDocker` was already idempotent through the `cleaned` flag on `DockerSpawnResult` (so both the finally path and any surviving guard / signal handler can call it without double-`rmSync` warnings); its JSDoc now states that contract explicitly because the exit-guard + finally pairing relies on it. New tests in `src/runtime/docker.test.ts` pin the invariants: (a) `cleanupDocker` invoked twice on the same `DockerSpawnResult` is a no-op the second time — sentinel files recreated under the overlay tempdir and sandbox tempdir after the first call survive the second call, and the cleared timeout timer never fires; (b) after a successful `withDockerExitGuard` body, `process.listenerCount("exit")` returns to its pre-run value and no new listener identity remains in `process.listeners("exit")`; (c) the same holds when the body throws — `await assert.rejects(...)` confirms the listener is still removed and `cleanupDocker` ran exactly once; (d) when `dockerResult` is `undefined`, the helper registers no listener and just returns the body's value. Existing E2E / run tests pass unchanged. Docs updated in `docs/sandboxing.md` (extended the **Signal-safe cleanup** paragraph under **Runtime behavior** to describe the `withDockerExitGuard` try/finally pairing, the abnormal-exit role of the guard, the no-op behavior for non-Docker runs, and `cleanupDocker`'s idempotency contract). - **Fix — Cross-module `run` applies the callee module's config:** Previously, when a workflow in module A reached a callee in module B via `run alias.workflow()`, both module B's module-level `config { … }` and the callee workflow's `config { … }` block were silently ignored — the caller's effective env carried through as-is. This was inconsistent with the other three call types (root entry, same-module `run`, cross-module `ensure`) and bit `.jaiph/ensure_ci_passes.jh` in particular: that module declares `agent.backend = "cursor"`, but when `engineer.jh` (backend `claude`) called `run ci.ensure_ci_passes()`, the CI-fix prompts silently ran on `claude`. A module's `config` should describe how *that* module's workflows run, regardless of who called them. `NodeWorkflowRuntime` now layers the callee's module-level metadata then the callee's workflow-level metadata on top of the caller's effective env when entering a cross-module `run` — same mechanics as the root-entry path, respecting `${NAME}_LOCKED` env flags (environment still always wins). The caller's scope is restored exactly when the call returns, so sibling isolation still holds. New / updated tests: `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` adds three cases — (a) module A (`agent.default_model = "model-a"`) runs `run b.show()` where module B sets `agent.default_model = "model-b"` and `show` logs the model: callee logs `model-b`, the next step in A's workflow logs `model-a` again (scope restored); (b) callee workflow-level config wins over callee module-level config on the cross-module path; (c) with `JAIPH_AGENT_MODEL` exported in the environment (locked), the callee's config does NOT override it. `e2e/tests/86_metadata_scope_nested.sh` and `e2e/tests/87_workflow_config.sh` are updated where they previously asserted the old (ignore) behavior — the nested call now sees the callee's backend during execution and the caller's backend is restored after. The now-stale `NOTE` comment at the top of `.jaiph/ensure_ci_passes.jh` (which warned that cross-module callers' config would win) is removed. Docs updated in `docs/configuration.md` ("Scoping across nested calls" table — the cross-module row no longer says the callee's config is ignored; "Module-level config" paragraph rewritten to describe nested `run` as same- *or* cross-module and to flag same-module `ensure` as the one remaining caller's-scope-as-is case). - **Tooling — Documentation prompts follow a vendored Diátaxis skill:** The three prompts in `.jaiph/docs_parity.jh` (`update_from_task`, `docs_page`, `docs_overview`) used to inline the same ad-hoc "expert technical writer" `role` const and repeat its guiding principles in prose. Each prompt now opens with an instruction to read and follow `.jaiph/skills/documentation-writer/SKILL.md` **before doing anything else**; the skill is referenced by explicit path so both the Claude and Cursor backends can `Read` it directly without depending on agent-specific skill auto-discovery directories. The skill is vendored from `github/awesome-copilot` at `.jaiph/skills/documentation-writer/SKILL.md` (committed, not gitignored; the file header records the upstream URL, blob SHA, and copy date so it can be re-synced) — vendoring rather than `npx skills add` at runtime keeps docs runs offline-safe and reproducible. It supplies the **Diátaxis** framework's four document types (tutorial / how-to / reference / explanation), the clarify → outline → write workflow, and the four guiding principles (clarity, accuracy, user-centricity, consistency). The inline `role` const is slimmed to project-specific context the skill does not cover — TypeScript / Bash fluency for verifying docs against the implementation, `docs/architecture.md` as the single source of truth (do not trust existing docs blindly), and the constraint that navigation between docs pages is provided by the Jekyll template in `docs/_layouts/docs.html` (no manual "More Documentation" blocks). `jaiph compile .jaiph` and `jaiph format --check .jaiph/docs_parity.jh` stay green. diff --git a/QUEUE.md b/QUEUE.md index 2a3fd7dc..ac028bd4 100644 --- a/QUEUE.md +++ b/QUEUE.md @@ -14,17 +14,6 @@ Process rules: *** -## Imported-channel sends never dispatch: normalize channel keys #dev-ready - -**Context.** Channel routes are registered in `NodeWorkflowRuntime` keyed by the **bare** channel name from `channel -> …` lines.

The runtime now caps the number of messages a single workflow frame may drain. The default cap is **1000**; override via the environment variable **`JAIPH_INBOX_MAX_DISPATCH`** (positive integer; non-numeric, empty, or non-positive values fall back to the default — resolved by a new `resolveInboxDispatchLimit(env)` helper at the top of `node-workflow-runtime.ts`). When the cap is exceeded `drainWorkflowQueue` aborts the owning workflow with status `1` and the error message `E_INBOX_DISPATCH_LIMIT: drained messages without quiescing — likely a circular send (channel ""); raise JAIPH_INBOX_MAX_DISPATCH if intentional`, where `` is the next un-drained message's channel (typically the channel involved in the cycle). New kernel tests in `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` pin the invariants: (a) a two-workflow circular send (`on_ping` enqueues on `pong`; `on_pong` enqueues on `ping`) fails the workflow with `E_INBOX_DISPATCH_LIMIT` instead of hanging, and the error names one of the cycle channels and the limit; (b) `JAIPH_INBOX_MAX_DISPATCH=5` against a self-loop triggers the cap after **exactly 5** `INBOX_DISPATCH_START` records in `run_summary.jsonl`; (c) multi-message fan-out below the cap (one producer enqueues 3 messages on a channel with 3 routed targets, cap = 5) still succeeds with no `E_INBOX_DISPATCH_LIMIT` in the summary. Existing inbox tests pass unchanged. Docs updated in `docs/inbox.md` (new **Dispatch cap** paragraph under [Dispatch loop](docs/inbox.md#dispatch-loop); the circular-sends bullet under [Error semantics](docs/inbox.md#error-semantics) now describes `E_INBOX_DISPATCH_LIMIT` and the env override instead of the old "no built-in iteration cap" warning), `docs/cli.md` (new `JAIPH_INBOX_MAX_DISPATCH` entry under **Execution behavior**), and `docs/jaiph-skill.md` (the inbox paragraph now states the 1000-message default cap and the env override). - **Fix — Imported-channel sends now dispatch:** Channel routes are registered in `NodeWorkflowRuntime`'s `ctx.routes` keyed by the **bare** channel name from `channel -> …` lines, but the send step looked the channel up with `this.workflowCtxStack[i].routes.has(step.channel)` where `step.channel` was the **verbatim token** left of `<-` (`src/runtime/kernel/node-workflow-runtime.ts`). So a validated cross-module send like `lib.topic <- "msg"` never matched the route registered as `topic` — the message was enqueued unrouted and silently dropped. `docs/inbox.md` previously documented this as a known footgun ("Module scope" paragraph) and steered users to bare-channel sends from the entry module. The send step in `node-workflow-runtime.ts` now normalizes `step.channel` once, at send time: after the validator (`validateChannelRef` in `src/transpile/validate.ts`) has already proven that an `alias.name` token refers to an existing imported channel, the runtime strips the `alias.` prefix and uses the bare name as `channelKey` for both the `routes.has(channelKey)` walk up the workflow stack and the `InboxMsg.channel` field. `lib.topic <-` and a bare `topic <-` therefore resolve to the same route key. The `INBOX_ENQUEUE` record in `run_summary.jsonl` carries the bare channel name; the audit copy is written to `inbox/NNN-.txt`. New E2E coverage in `e2e/tests/91_inbox_dispatch.sh` ("Imported channel send: lib.topic normalizes to topic for routing") writes the failing-today scenario as a test first — entry module declares `channel topic -> handler` and imports `lib`, `lib` declares `channel topic`, the entry workflow sends `lib.topic <- "x"` — then asserts `handler` is invoked with payload `"x"`, the inbox audit file is `inbox/001-topic.txt` containing `x`, and the `INBOX_ENQUEUE` line in `run_summary.jsonl` records `channel: "topic"` (bare, alias prefix stripped). Docs updated in `docs/inbox.md` — the "Module scope" paragraph under [Who registers routes and who drains](docs/inbox.md#who-registers-routes-and-who-drains) is rewritten to describe the normalized behavior (and references `validateChannelRef` as the guarantee that any `alias.` prefix the runtime strips already names a real imported channel), the imported-channel bullet under **Send operator** drops the "literal token" caveat, and the [Send operator](docs/inbox.md#send-operator--channel_ref-rhs) paragraph clarifies that `sendChannel` is the bare channel name used for both the route lookup and the audit filename. - **Fix — Docker-run path no longer leaks the `process.on("exit")` cleanup guard:** In `src/cli/commands/run.ts` (`runWorkflow`), when `spawnExec` returned a `dockerResult`, an `exitGuard` callback was registered with `process.on("exit", exitGuard)` so that, if the host CLI crashed before the run finished, `cleanupDocker(dockerResult)` would still tear down the copy-mode sandbox directory and clear the timeout timer. The matching `process.removeListener("exit", exitGuard)` only ran inside the `if (dockerResult)` block *after* `await waitForRunExit(...)` resolved normally — so if anything between registration and removal threw (stream wiring, the awaited child exit, buffer draining), the listener stayed on the `process` object for the rest of the host CLI's lifetime and `cleanupDocker` would fire again at process exit on an already-cleaned container, also fattening the `exit`-listener list across nested or repeated runs. Registration and removal are now paired in a `try { … } finally { … }` block via a new helper `withDockerExitGuard(dockerResult, body)` exported from `src/runtime/docker.ts`. The helper registers the guard, runs the spawn-to-exit body inside `try`, and in `finally` — on both normal return *and* on throw — removes the listener and calls `cleanupDocker(dockerResult)`. The guard itself stays registered for the abnormal-exit case (that is its purpose); only the normal and thrown-body paths now deterministically remove it. When `dockerResult` is `undefined` (non-Docker run), no listener is registered at all. `cleanupDocker` was already idempotent through the `cleaned` flag on `DockerSpawnResult` (so both the finally path and any surviving guard / signal handler can call it without double-`rmSync` warnings); its JSDoc now states that contract explicitly because the exit-guard + finally pairing relies on it. New tests in `src/runtime/docker.test.ts` pin the invariants: (a) `cleanupDocker` invoked twice on the same `DockerSpawnResult` is a no-op the second time — sentinel files recreated under the overlay tempdir and sandbox tempdir after the first call survive the second call, and the cleared timeout timer never fires; (b) after a successful `withDockerExitGuard` body, `process.listenerCount("exit")` returns to its pre-run value and no new listener identity remains in `process.listeners("exit")`; (c) the same holds when the body throws — `await assert.rejects(...)` confirms the listener is still removed and `cleanupDocker` ran exactly once; (d) when `dockerResult` is `undefined`, the helper registers no listener and just returns the body's value. Existing E2E / run tests pass unchanged. Docs updated in `docs/sandboxing.md` (extended the **Signal-safe cleanup** paragraph under **Runtime behavior** to describe the `withDockerExitGuard` try/finally pairing, the abnormal-exit role of the guard, the no-op behavior for non-Docker runs, and `cleanupDocker`'s idempotency contract). - **Fix — Cross-module `run` applies the callee module's config:** Previously, when a workflow in module A reached a callee in module B via `run alias.workflow()`, both module B's module-level `config { … }` and the callee workflow's `config { … }` block were silently ignored — the caller's effective env carried through as-is. This was inconsistent with the other three call types (root entry, same-module `run`, cross-module `ensure`) and bit `.jaiph/ensure_ci_passes.jh` in particular: that module declares `agent.backend = "cursor"`, but when `engineer.jh` (backend `claude`) called `run ci.ensure_ci_passes()`, the CI-fix prompts silently ran on `claude`. A module's `config` should describe how *that* module's workflows run, regardless of who called them. `NodeWorkflowRuntime` now layers the callee's module-level metadata then the callee's workflow-level metadata on top of the caller's effective env when entering a cross-module `run` — same mechanics as the root-entry path, respecting `${NAME}_LOCKED` env flags (environment still always wins). The caller's scope is restored exactly when the call returns, so sibling isolation still holds. New / updated tests: `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` adds three cases — (a) module A (`agent.default_model = "model-a"`) runs `run b.show()` where module B sets `agent.default_model = "model-b"` and `show` logs the model: callee logs `model-b`, the next step in A's workflow logs `model-a` again (scope restored); (b) callee workflow-level config wins over callee module-level config on the cross-module path; (c) with `JAIPH_AGENT_MODEL` exported in the environment (locked), the callee's config does NOT override it. `e2e/tests/86_metadata_scope_nested.sh` and `e2e/tests/87_workflow_config.sh` are updated where they previously asserted the old (ignore) behavior — the nested call now sees the callee's backend during execution and the caller's backend is restored after.

But `resolveRecoverLimit` in `src/runtime/kernel/node-workflow-runtime.ts` read only `moduleMeta?.run?.recoverLimit ?? 10`, so a workflow-level `run.recover_limit = 3` parsed and validated fine but was silently ignored at retry time — a `run … recover` step inside that workflow still used the module-level cap (or the default of 10). `docs/configuration.md` documented this as an explicit exception ("`run.recover_limit` is an exception: only **module-level** values affect `run … recover`"), making it a trap: config that validates but does nothing. `NodeWorkflowRuntime` now resolves `run.recover_limit` through the same precedence as other run keys: it consults the **active workflow's** metadata scope first (the top of `workflowCtxStack`, whose `workflowMeta` is captured when the workflow frame is pushed), then falls back to the module-level metadata of the file owning the current step's scope, then to the default of `10`. The workflow-frame side of the wiring is a new `workflowMeta?: WorkflowMetadata` field on `WorkflowContext` populated at frame-creation time from `resolved.workflow.metadata`, so cross-module `run` calls correctly see the callee workflow's own config (the cross-module call already pushes a new frame). New tests in `integration/sample-build/recover-handle.test.ts` pin the invariants: (a) a workflow with `config { run.recover_limit = 2 }` calling a failing script via `run failing() recover(e) { … }`, with module-level `run.recover_limit = 50` set as a deliberately wrong fallback, executes the script exactly **3 times** (1 initial + 2 retries) — verified by reading a counter file that the failing script increments and exits non-zero on every attempt; (b) a sibling workflow in the same module without its own `config` block still uses the module-level value (`config { run.recover_limit = 2 }` at module level → 3 attempts), proving workflow-level config is correctly scoped per-workflow and does not bleed into siblings (an unrelated sibling workflow's own `config { run.recover_limit = 50 }` is also present in the fixture to prove it does not leak into `default`). Both tests run `dist/src/cli.js` end-to-end under `JAIPH_DOCKER_ENABLED=false`. Docs updated to delete the exception text from `docs/configuration.md` (three places: the "Three ways to configure" intro, the "Run keys" table row, and the "Workflow-level config" rules) and to refresh `docs/grammar.md`, `docs/jaiph-skill.md`, `docs/language.md`, and `docs/spec-async-handles.md` so the retry-limit override description matches the now-standard precedence (workflow-level > module-level > default 10). `grep -rn "workflow-level run.recover_limit" docs/` returns nothing stale. - **Feature — Inbox dispatch iteration cap:** `drainWorkflowQueue` in `src/runtime/kernel/node-workflow-runtime.ts` walked the in-memory channel queue with `while (cursor < queue.length)` and had no upper bound — dispatched targets that sent on the same (or a routed) channel could append to the same queue indefinitely, so a circular send (A routes to B, B sends back to A's channel) looped until the host OOM'd. `docs/inbox.md` previously *documented* the footgun ("Avoid unbounded circular sends") rather than the runtime enforcing a bound. The runtime now caps the number of messages a single workflow frame may drain. The default cap is **1000**; override via the environment variable **`JAIPH_INBOX_MAX_DISPATCH`** (positive integer; non-numeric, empty, or non-positive values fall back to the default — resolved by a new `resolveInboxDispatchLimit(env)` helper at the top of `node-workflow-runtime.ts`). When the cap is exceeded `drainWorkflowQueue` aborts the owning workflow with status `1` and the error message `E_INBOX_DISPATCH_LIMIT: drained messages without quiescing — likely a circular send (channel ""); raise JAIPH_INBOX_MAX_DISPATCH if intentional`, where `` is the next un-drained message's channel (typically the channel involved in the cycle). New kernel tests in `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` pin the invariants: (a) a two-workflow circular send (`on_ping` enqueues on `pong`; `on_pong` enqueues on `ping`) fails the workflow with `E_INBOX_DISPATCH_LIMIT` instead of hanging, and the error names one of the cycle channels and the limit; (b) `JAIPH_INBOX_MAX_DISPATCH=5` against a self-loop triggers the cap after **exactly 5** `INBOX_DISPATCH_START` records in `run_summary.jsonl`; (c) multi-message fan-out below the cap (one producer enqueues 3 messages on a channel with 3 routed targets, cap = 5) still succeeds with no `E_INBOX_DISPATCH_LIMIT` in the summary. Existing inbox tests pass unchanged. Docs updated in `docs/inbox.md` (new **Dispatch cap** paragraph under [Dispatch loop](docs/inbox.md#dispatch-loop); the circular-sends bullet under [Error semantics](docs/inbox.md#error-semantics) now describes `E_INBOX_DISPATCH_LIMIT` and the env override instead of the old "no built-in iteration cap" warning), `docs/cli.md` (new `JAIPH_INBOX_MAX_DISPATCH` entry under **Execution behavior**), and `docs/jaiph-skill.md` (the inbox paragraph now states the 1000-message default cap and the env override). - **Fix — Imported-channel sends now dispatch:** Channel routes are registered in `NodeWorkflowRuntime`'s `ctx.routes` keyed by the **bare** channel name from `channel -> …` lines, but the send step looked the channel up with `this.workflowCtxStack[i].routes.has(step.channel)` where `step.channel` was the **verbatim token** left of `<-` (`src/runtime/kernel/node-workflow-runtime.ts`). So a validated cross-module send like `lib.topic <- "msg"` never matched the route registered as `topic` — the message was enqueued unrouted and silently dropped. `docs/inbox.md` previously documented this as a known footgun ("Module scope" paragraph) and steered users to bare-channel sends from the entry module. The send step in `node-workflow-runtime.ts` now normalizes `step.channel` once, at send time: after the validator (`validateChannelRef` in `src/transpile/validate.ts`) has already proven that an `alias.name` token refers to an existing imported channel, the runtime strips the `alias.` prefix and uses the bare name as `channelKey` for both the `routes.has(channelKey)` walk up the workflow stack and the `InboxMsg.channel` field. `lib.topic <-` and a bare `topic <-` therefore resolve to the same route key. The `INBOX_ENQUEUE` record in `run_summary.jsonl` carries the bare channel name; the audit copy is written to `inbox/NNN-.txt`. New E2E coverage in `e2e/tests/91_inbox_dispatch.sh` ("Imported channel send: lib.topic normalizes to topic for routing") writes the failing-today scenario as a test first — entry module declares `channel topic -> handler` and imports `lib`, `lib` declares `channel topic`, the entry workflow sends `lib.topic <- "x"` — then asserts `handler` is invoked with payload `"x"`, the inbox audit file is `inbox/001-topic.txt` containing `x`, and the `INBOX_ENQUEUE` line in `run_summary.jsonl` records `channel: "topic"` (bare, alias prefix stripped). Docs updated in `docs/inbox.md` — the "Module scope" paragraph under [Who registers routes and who drains](docs/inbox.md#who-registers-routes-and-who-drains) is rewritten to describe the normalized behavior (and references `validateChannelRef` as the guarantee that any `alias.` prefix the runtime strips already names a real imported channel), the imported-channel bullet under **Send operator** drops the "literal token" caveat, and the [Send operator](docs/inbox.md#send-operator--channel_ref-rhs) paragraph clarifies that `sendChannel` is the bare channel name used for both the route lookup and the audit filename. - **Fix — Docker-run path no longer leaks the `process.on("exit")` cleanup guard:** In `src/cli/commands/run.ts` (`runWorkflow`), when `spawnExec` returned a `dockerResult`, an `exitGuard` callback was registered with `process.on("exit", exitGuard)` so that, if the host CLI crashed before the run finished, `cleanupDocker(dockerResult)` would still tear down the copy-mode sandbox directory and clear the timeout timer. The matching `process.removeListener("exit", exitGuard)` only ran inside the `if (dockerResult)` block *after* `await waitForRunExit(...)` resolved normally — so if anything between registration and removal threw (stream wiring, the awaited child exit, buffer draining), the listener stayed on the `process` object for the rest of the host CLI's lifetime and `cleanupDocker` would fire again at process exit on an already-cleaned container, also fattening the `exit`-listener list across nested or repeated runs. Registration and removal are now paired in a `try { … } finally { … }` block via a new helper `withDockerExitGuard(dockerResult, body)` exported from `src/runtime/docker.ts`. The helper registers the guard, runs the spawn-to-exit body inside `try`, and in `finally` — on both normal return *and* on throw — removes the listener and calls `cleanupDocker(dockerResult)`. The guard itself stays registered for the abnormal-exit case (that is its purpose); only the normal and thrown-body paths now deterministically remove it. When `dockerResult` is `undefined` (non-Docker run), no listener is registered at all. `cleanupDocker` was already idempotent through the `cleaned` flag on `DockerSpawnResult` (so both the finally path and any surviving guard / signal handler can call it without double-`rmSync` warnings); its JSDoc now states that contract explicitly because the exit-guard + finally pairing relies on it. New tests in `src/runtime/docker.test.ts` pin the invariants: (a) `cleanupDocker` invoked twice on the same `DockerSpawnResult` is a no-op the second time — sentinel files recreated under the overlay tempdir and sandbox tempdir after the first call survive the second call, and the cleared timeout timer never fires; (b) after a successful `withDockerExitGuard` body, `process.listenerCount("exit")` returns to its pre-run value and no new listener identity remains in `process.listeners("exit")`; (c) the same holds when the body throws — `await assert.rejects(...)` confirms the listener is still removed and `cleanupDocker` ran exactly once; (d) when `dockerResult` is `undefined`, the helper registers no listener and just returns the body's value. Existing E2E / run tests pass unchanged. Docs updated in `docs/sandboxing.md` (extended the **Signal-safe cleanup** paragraph under **Runtime behavior** to describe the `withDockerExitGuard` try/finally pairing, the abnormal-exit role of the guard, the no-op behavior for non-Docker runs, and `cleanupDocker`'s idempotency contract). diff --git a/QUEUE.md b/QUEUE.md index 761f808c..cde6348e 100644 --- a/QUEUE.md +++ b/QUEUE.md @@ -14,17 +14,6 @@ Process rules: *** -## Honor workflow-level `run.recover_limit` #dev-ready - -**Context.** A workflow body may open with a `config { … }` block that overrides `agent.*` and `run.*` keys.

The documented workarounds — `match` (which forces a wildcard arm and value-shaped bodies) or a `catch`-as-failure-branch — were the single biggest ergonomic gap agents hit when authoring workflows and rules. `if` now accepts an optional `else { … }` clause that runs when the condition is false. Surface syntax: `} else {` must sit on the **same line** as the closing `}` of the `if` body — `else` on its own line is `E_PARSE` (`"else" must appear on the same line as the closing "}" of an "if" block`); `else` without a preceding `if` is the same `E_PARSE`; and `else if` chaining is rejected with a dedicated `E_PARSE` (`"else if" chaining is not supported; nest an "if" inside the "else" block, or use "match" for multi-way branching`) — a bare `else` containing a nested `if` is fine. `if` / `else` remains a **statement** (no value production); `const x = if …` and `return if …` are still parse errors, and value-shaped branching is still expressed with `match`. The `else` body uses a brace block of the same step forms allowed in the surrounding workflow / rule body — rule scope still rejects `prompt`, channel sends, `run async`, and `run` to a workflow inside `else`, exactly as it does inside the `if` body. The parser entry is the `if` row of the `STATEMENT` dispatch table in `src/parse/workflow-brace.ts`: `tryParseIf` calls `parseBraceBlockBody` with a new `allowElseTerminator: true` opt that recognizes `} else {` as a block terminator and signals it via a new `closedWithElse` field on the return tuple, then `tryParseIf` parses the else body with a second `parseBraceBlockBody` call (without the opt, so the else body terminates only on `}`). A dedicated `tryParseElseError` row on `else` produces the same two error messages when a stray `else` appears as a top-level statement (outside an `if` body), so the diagnostic doesn't depend on which side of the `}` the parser hits. AST: `WorkflowStepDef`'s `if` variant gains an optional `elseBody?: WorkflowStepDef[]` (absent when there is no `else`, preserving the old shape byte-for-byte). Validator (`src/transpile/validate.ts`'s `walkStepTree`) descends into `elseBody` with the same scope as `body`, so binding rules and per-step rule/workflow gates apply uniformly to both arms. Runtime (`src/runtime/kernel/node-workflow-runtime.ts`): the `if` case picks `step.body` when the condition is met and `step.elseBody` otherwise, executes only the chosen branch's steps in order, and propagates any non-zero status or `return` value through the existing `mergeStepResult` path — the false-with-no-else path is still a no-op. Formatter (`src/format/emit.ts`'s `emitStep`): emits canonical `} else {` between the two arms when `elseBody` is set; `jaiph format` is idempotent on `if/else` (formatter test in `src/format/emit.test.ts`). New txtar fixtures cover (a) `if/else` in a workflow, in a rule, and a nested `if` inside an `else` block (`test-fixtures/compiler-txtar/valid.txt`); (b) the three parse-error shapes — `else` on its own line, bare `else` without a preceding `if`, and `else if (…)` chaining (`test-fixtures/compiler-txtar/parse-errors.txt`); and (c) rule-scope validation rejecting `const … = prompt …` inside an `else` block in a rule (`test-fixtures/compiler-txtar/validate-errors.txt`). A golden AST fixture pair (`test-fixtures/golden-ast/fixtures/if-else.jh` + `test-fixtures/golden-ast/expected/if-else.json`) pins the tree shape for an `if/else` statement. New runtime E2E `e2e/tests/136_if_else_branch.sh` runs the same `.jh` source twice: with `status="ok"` the then-branch logs `healthy` and `done`, with `status="bad"` the else-branch logs `unhealthy: bad` and `done` — proving only the chosen arm executes — plus the same shape inside a rule (then-branch fails the workflow on empty input; else-branch passes the rule and the workflow continues to `log "validated"`). Docs updated in `docs/grammar.md` (rewrote the `if` section to document `else`, added the `else_clause` production to the EBNF), `docs/language.md` (updated the **`if` — Conditional Guard** section: dropped the "No `else` branch" claim and added a `} else {` example), and `docs/jaiph-skill.md` (replaced the "`if` has **no `else`**" bullet with the new `} else {` rules and the no-`else if` chaining caveat); `docs/contributing.md` bumps the golden AST fixture count from 9 to 10 and names the new `if-else` fixture. - **Fix — Workflow-level `run.recover_limit` now applies:** A workflow body may open with a `config { … }` block that overrides `agent.*` and `run.*` keys, and the precedence chain (workflow-level > module-level > defaults) was already documented for every other run key. But `resolveRecoverLimit` in `src/runtime/kernel/node-workflow-runtime.ts` read only `moduleMeta?.run?.recoverLimit ?? 10`, so a workflow-level `run.recover_limit = 3` parsed and validated fine but was silently ignored at retry time — a `run … recover` step inside that workflow still used the module-level cap (or the default of 10). `docs/configuration.md` documented this as an explicit exception ("`run.recover_limit` is an exception: only **module-level** values affect `run … recover`"), making it a trap: config that validates but does nothing. `NodeWorkflowRuntime` now resolves `run.recover_limit` through the same precedence as other run keys: it consults the **active workflow's** metadata scope first (the top of `workflowCtxStack`, whose `workflowMeta` is captured when the workflow frame is pushed), then falls back to the module-level metadata of the file owning the current step's scope, then to the default of `10`. The workflow-frame side of the wiring is a new `workflowMeta?: WorkflowMetadata` field on `WorkflowContext` populated at frame-creation time from `resolved.workflow.metadata`, so cross-module `run` calls correctly see the callee workflow's own config (the cross-module call already pushes a new frame). New tests in `integration/sample-build/recover-handle.test.ts` pin the invariants: (a) a workflow with `config { run.recover_limit = 2 }` calling a failing script via `run failing() recover(e) { … }`, with module-level `run.recover_limit = 50` set as a deliberately wrong fallback, executes the script exactly **3 times** (1 initial + 2 retries) — verified by reading a counter file that the failing script increments and exits non-zero on every attempt; (b) a sibling workflow in the same module without its own `config` block still uses the module-level value (`config { run.recover_limit = 2 }` at module level → 3 attempts), proving workflow-level config is correctly scoped per-workflow and does not bleed into siblings (an unrelated sibling workflow's own `config { run.recover_limit = 50 }` is also present in the fixture to prove it does not leak into `default`). Both tests run `dist/src/cli.js` end-to-end under `JAIPH_DOCKER_ENABLED=false`. Docs updated to delete the exception text from `docs/configuration.md` (three places: the "Three ways to configure" intro, the "Run keys" table row, and the "Workflow-level config" rules) and to refresh `docs/grammar.md`, `docs/jaiph-skill.md`, `docs/language.md`, and `docs/spec-async-handles.md` so the retry-limit override description matches the now-standard precedence (workflow-level > module-level > default 10). `grep -rn "workflow-level run.recover_limit" docs/` returns nothing stale. - **Feature — Inbox dispatch iteration cap:** `drainWorkflowQueue` in `src/runtime/kernel/node-workflow-runtime.ts` walked the in-memory channel queue with `while (cursor < queue.length)` and had no upper bound — dispatched targets that sent on the same (or a routed) channel could append to the same queue indefinitely, so a circular send (A routes to B, B sends back to A's channel) looped until the host OOM'd. `docs/inbox.md` previously *documented* the footgun ("Avoid unbounded circular sends") rather than the runtime enforcing a bound. The runtime now caps the number of messages a single workflow frame may drain. The default cap is **1000**; override via the environment variable **`JAIPH_INBOX_MAX_DISPATCH`** (positive integer; non-numeric, empty, or non-positive values fall back to the default — resolved by a new `resolveInboxDispatchLimit(env)` helper at the top of `node-workflow-runtime.ts`). When the cap is exceeded `drainWorkflowQueue` aborts the owning workflow with status `1` and the error message `E_INBOX_DISPATCH_LIMIT: drained messages without quiescing — likely a circular send (channel ""); raise JAIPH_INBOX_MAX_DISPATCH if intentional`, where `` is the next un-drained message's channel (typically the channel involved in the cycle). New kernel tests in `src/runtime/kernel/node-workflow-runtime.artifacts.test.ts` pin the invariants: (a) a two-workflow circular send (`on_ping` enqueues on `pong`; `on_pong` enqueues on `ping`) fails the workflow with `E_INBOX_DISPATCH_LIMIT` instead of hanging, and the error names one of the cycle channels and the limit; (b) `JAIPH_INBOX_MAX_DISPATCH=5` against a self-loop triggers the cap after **exactly 5** `INBOX_DISPATCH_START` records in `run_summary.jsonl`; (c) multi-message fan-out below the cap (one producer enqueues 3 messages on a channel with 3 routed targets, cap = 5) still succeeds with no `E_INBOX_DISPATCH_LIMIT` in the summary. Existing inbox tests pass unchanged. Docs updated in `docs/inbox.md` (new **Dispatch cap** paragraph under [Dispatch loop](docs/inbox.md#dispatch-loop); the circular-sends bullet under [Error semantics](docs/inbox.md#error-semantics) now describes `E_INBOX_DISPATCH_LIMIT` and the env override instead of the old "no built-in iteration cap" warning), `docs/cli.md` (new `JAIPH_INBOX_MAX_DISPATCH` entry under **Execution behavior**), and `docs/jaiph-skill.md` (the inbox paragraph now states the 1000-message default cap and the env override). - **Fix — Imported-channel sends now dispatch:** Channel routes are registered in `NodeWorkflowRuntime`'s `ctx.routes` keyed by the **bare** channel name from `channel -> …` lines, but the send step looked the channel up with `this.workflowCtxStack[i].routes.has(step.channel)` where `step.channel` was the **verbatim token** left of `<-` (`src/runtime/kernel/node-workflow-runtime.ts`). So a validated cross-module send like `lib.topic <- "msg"` never matched the route registered as `topic` — the message was enqueued unrouted and silently dropped. `docs/inbox.md` previously documented this as a known footgun ("Module scope" paragraph) and steered users to bare-channel sends from the entry module. The send step in `node-workflow-runtime.ts` now normalizes `step.channel` once, at send time: after the validator (`validateChannelRef` in `src/transpile/validate.ts`) has already proven that an `alias.name` token refers to an existing imported channel, the runtime strips the `alias.` prefix and uses the bare name as `channelKey` for both the `routes.has(channelKey)` walk up the workflow stack and the `InboxMsg.channel` field. `lib.topic <-` and a bare `topic <-` therefore resolve to the same route key. The `INBOX_ENQUEUE` record in `run_summary.jsonl` carries the bare channel name; the audit copy is written to `inbox/NNN-.txt`. New E2E coverage in `e2e/tests/91_inbox_dispatch.sh` ("Imported channel send: lib.topic normalizes to topic for routing") writes the failing-today scenario as a test first — entry module declares `channel topic -> handler` and imports `lib`, `lib` declares `channel topic`, the entry workflow sends `lib.topic <- "x"` — then asserts `handler` is invoked with payload `"x"`, the inbox audit file is `inbox/001-topic.txt` containing `x`, and the `INBOX_ENQUEUE` line in `run_summary.jsonl` records `channel: "topic"` (bare, alias prefix stripped). Docs updated in `docs/inbox.md` — the "Module scope" paragraph under [Who registers routes and who drains](docs/inbox.md#who-registers-routes-and-who-drains) is rewritten to describe the normalized behavior (and references `validateChannelRef` as the guarantee that any `alias.` prefix the runtime strips already names a real imported channel), the imported-channel bullet under **Send operator** drops the "literal token" caveat, and the [Send operator](docs/inbox.md#send-operator--channel_ref-rhs) paragraph clarifies that `sendChannel` is the bare channel name used for both the route lookup and the audit filename. diff --git a/QUEUE.md b/QUEUE.md index cde6348e..0e7c571e 100644 --- a/QUEUE.md +++ b/QUEUE.md @@ -14,31 +14,6 @@ Process rules: *** -## Add `else` branch to `if` #dev-ready - -**Context.** `if var == "value" { … }` exists in workflows and rules, but there is no `else`.

Tutorials: docs/first-workflow.md (permalink /tutorials/first-workflow, absorbs /getting-started) and docs/first-agent-run.md (permalink /tutorials/first-agent-run) author the two learning-oriented entry points from source first and reconcile against docs/_legacy/. IA finalization: docs/_layouts/docs.html nav is regrouped into the five Diátaxis sections in order — Tutorials, How-to guides, Reference, Explanation, Contributing — each listing exactly its published pages with active-page highlighting preserved. docs/index.html's top nav and footer lead with the first tutorial and the how-to index instead of a flat docs link. jaiph-skill.md absorbs /contributing.md for parity with the other live pages. architecture.md drops /getting-started from its redirect_from list (now owned by the new tutorial), so each historical permalink resolves through exactly one stub. Two new integration tests grade the work: docs-tutorials-task6.test.ts asserts the tutorial front-matter, nav presence, redirect ownership, and that the first .jh fence in first-workflow.md is executable end- to-end against the CLI; docs-nav-structure-task7.test.ts asserts the five nav-group headings appear in order and that every published diataxis: page sits under the matching section exactly once. README.md is updated to surface the two tutorials in the top link bar and the Docs-note callout, and to repoint the remaining legacy getting-started references at the live tutorial. No runtime, CLI, or language behavior changes.

The Jekyll nav in `docs/_layouts/docs.html` is regrouped into **five labeled `
  • ` sections in the documented Diátaxis order — Tutorials → How-to guides → Reference → Explanation → Contributing** — each containing exactly the published pages whose `diataxis:` front-matter matches the section (`tutorial` → Tutorials, `how-to` → How-to guides, `reference` → Reference, `explanation` → Explanation, `contributor` → Contributing). The active-page highlighting (`{% if page.permalink == '/...' %} class="docs-nav-active" aria-current="page"{% endif %}`) is preserved on every entry, and the contributor Agent Skill link continues to point at the in-site permalink `/jaiph-skill` (the raw-`jaiph-skill.md` URL stays in `README.md` and `docs/index.html` because those are the entry points agents themselves consume and they need the unrendered Markdown — that contract is unchanged from task 2). Tutorials lead the panel because they are the entry point for newcomers; Contributing trails because it is in-repo developer surface, not user-facing. The landing page (`docs/index.html`) entry points are repointed to lead with the **first tutorial** and the **how-to index** (not a flat page list): the top-nav `Docs` link is split into `Tutorial` (→ `/tutorials/first-workflow`) and `How-to` (→ `/how-to/install`), and the footer `Architecture` link is replaced with the same `Tutorial` + `How-to` pair so the landing page guides newcomers down the tutorial path and operators down the how-to path rather than dumping them on an explanation page. The redirect sweep adds `/contributing.md` to `docs/jaiph-skill.md`'s `redirect_from:` (jaiph-skill.md already absorbed `/contributing`; the `.md` form is added for parity with the other live pages that absorb both the bare permalink and the `.md` form held by the legacy page). Every URL in the pre-redesign nav (`/getting-started`, `/setup`, `/libraries`, `/artifacts`, `/language`, `/grammar`, `/cli`, `/configuration`, `/testing`, `/spec-async-handles`, `/inbox`, `/hooks`, `/sandboxing`, `/architecture`, `/contributing`) now resolves to its new home — either directly (the slug is unchanged on a live page) or via a single `jekyll-redirect-from` stub emitted from the absorbing page's `redirect_from:` list. `bundle exec jekyll build` exits 0 with no missing-link / front-matter warnings and emits no page from `docs/_legacy/` (already build-excluded via the `_config.yml` `exclude:` list from task 1). A new integration test `integration/docs-nav-structure-task7.test.ts` (Node `--test`, auto-picked up by `npm test`) graders this task end-to-end as two checks: (1) the nav layout's `
  • ` headings are exactly `["Tutorials", "How-to guides", "Reference", "Explanation", "Contributing"]` in that order — drift in heading text or ordering fails the test; (2) every published `docs/*.md` with a `diataxis:` front-matter value appears under the matching section exactly once (no miss / no miscategorisation / no cross-section duplicate), and every section's link list equals the set of permalinks for its diataxis bucket — so adding a new how-to page without nav-wiring it, or accidentally listing a tutorial under Explanation, fails the test. The existing docs-lint harness from task 2 (`integration/docs-structure.test.ts`) continues to enforce the historical-permalink resolution check (`every historical nav permalink still resolves`) — that test mines every `'' | relative_url` reference from `git log -p --all -- docs/_layouts/docs.html` and asserts the URL still resolves via a published page or a `redirect_from:` alias, which is the redirect-coverage backstop for this task. With this task in, the IA is complete: all four user-facing Diátaxis quadrants are nav-grouped under their section heading, plus the in-repo Contributing bucket; the remaining task 8 finalizes the contributor page replacements and the README/landing sweep. No runtime, CLI, or language behavior changes; the only edits are to `docs/_layouts/docs.html`, `docs/index.html`, and `docs/jaiph-skill.md`'s front-matter. +- **Docs — Diátaxis Tutorials pass: guided first-success paths (docs redesign 6/8):** Fourth content task in the [Diátaxis](https://diataxis.fr/) docs rewrite. Two learning-oriented pages now land in `docs/` as published Diátaxis tutorials, each authored greenfield from the TypeScript/Bash source plus `docs/architecture.md` first and only then reconciled against `docs/_legacy/getting-started.md` (per the anti-bias protocol in `.jaiph/skills/documentation-writer/SKILL.md`). Both pages walk a newcomer from "have nothing" to a working first-success outcome, with every command copy-pasteable and one happy path only — branching/optional knobs link out to the relevant How-to or Reference page rather than expanding inline: `docs/first-workflow.md` (permalink `/tutorials/first-workflow`, `redirect_from: /getting-started`, `/getting-started.md`) — install → write a six-line script-only `.jh` with one `script` step and one `workflow default(who)` that returns the script's stdout → run with `jaiph run ./hello.jh "Adam"` → read the live progress tree, the printed return value, and the durable files under `.jaiph/runs//
