+# fullsend shim workflow (per-repo installation mode)
+# Routes events to agent workflows via reusable-dispatch.yml.
+# All agent execution happens in this repo's context — no external
+# config repo is needed.
+#
+# Security: pull_request_target runs the BASE branch version of this workflow,
+# preventing PRs from modifying it to exfiltrate credentials.
+# This shim never checks out PR code, so it is not vulnerable to "pwn request"
+# attacks.
+#
+# Routing: this shim forwards the raw event context to reusable-dispatch.yml,
+# which determines the stage and conditionally calls the appropriate
+# reusable-{stage}.yml workflow. Adding a new stage requires only a case
+# branch in reusable-dispatch.yml — zero changes to this repo.
+#
+# Concurrency: per-role cancel-in-progress groups live in reusable-dispatch.yml
+# stage jobs and agent-scoped groups on reusable-{stage}.yml — not on this shim.
+# A monolithic shim group would serialize unrelated roles and drop pending runs (#2452).
