docs(architecture): the spine told once — narrative out, numbers to the ledger, one tree drawing

[drewstone]

What

The spine-cluster consolidation from the grounded DX evaluation: architecture.md is the decreed canonical spine, but it told the atom/tree/timescales 3x each, carried dated session narrative, and mirrored every gate number that already lives in the ledger.

• docs/architecture.md (888 -> 668 lines). Header loses the dated stamps + status inventory (live status = .evolve/current.json + the memory ledger; the wins-on-conflict rule stays). The session-narrative §0 is deleted (each locked decision verified restated: atom -> §1, selector != judge -> §1/§7, scaffold-then-GEPA -> §9, moat -> §8, sandbox driver -> §3). Gate-A/Gate-B inline definitions become pointers to their canonical homes (interpretations §5 / learning-flywheel.md). §11 collapses to a ledger pointer keeping only the two timeless laws verbatim (domain-boundary, honesty). §12 is deleted (executed to-do list; the vocabulary law moves to glossary.md; bench/src/{refine-loop,run-pool,directives}.ts verified present). §13/§14 merge into ONE picture book with a single tree drawing.
• Two stale factual claims corrected: §13.7 said the ask/answer edges were "designed, not built" — ask_parent/answer_question are shipped (src/mcp/tools/coordination.ts:159-160, priority-queued on the event bus); and two anchors re-verified against code (Agent at supervise/types.ts:49, not :51; createExecutor at supervise/runtime.ts:1517, not :1137).
• docs/architecture-interpretations.md (236 -> 233 lines). Status header + §2 selector numbers + §5 measured paragraph become qualitative verdict + ledger pointer; the five lenses, §4 verdict, and the Gate-A definition stay verbatim as the audit record they are. The dangling architecture.md §11 cite now points at the ledger.
• docs/glossary.md (70 -> 72 lines). Absorbs the vocabulary law (qualify driver-worker loop by timescale; benchmark = adapter; selector picks, never the judge) so the §12 deletion is lossless.

Every deleted number was verified present in .evolve/current.json or the memory ledger before deletion; the one missing cluster (the FinSearchComp SOTA breakdown) was appended to the ledger first. concepts.md, execution-model.md, and canonical-api §1/§1.5 are untouched per the evaluation verdicts.

Note for external readers: architecture.md §11/§12 deep-links now resolve to the ledger pointer; the picture book keeps the §13 number.

Checks

• pnpm run docs:check — green (freshness gate: version pins, 10 citations, prose symbols across the 3 curated docs)
• pnpm run lint / pnpm run typecheck — green
• grep -c '2026-' docs/architecture.md -> 0; cross-file grep for refs to deleted sections -> 0
