     > Removal is ~1,000 lines and mechanical: `.pre-commit-hooks.yaml`, `check-release-needed.sh`, both tests, the hook block at ~~`.pre-commit-config.yaml:194-201`~~ → `.pre-commit-config.yaml:186-193`, the ~~`gates.md:83`~~ → `gates.md:96` row and its "External consumers" section (`gates.md:789`). Tags are inert and can stay. **The one real loss:** `test-vale-hooks-consumer.sh` is the sole test exercising the entry-resolution path that once shipped broken — it goes only *with* the manifest, never while it stays. Reversal cost is bounded provided ADR-0014 and `LESSONS.md:101,105` are kept: they preserve the `entry[0]`-only constraint that took three review rounds to find.

The `check-release-needed` block is now `.pre-commit-config.yaml:186-193` (`grep -n "id: check-release-needed"`); the three internal `repo: local` wirings' `entry:` lines are `:221` (`skill-size-check`), `:254` and `:269` (the two `vale-audit-prefilter-*` hooks, both now on `factory-audit`'s one `vale-wrap.sh`); the `check-release-needed` table row is `gates.md:96` and the "External consumers" section heading is `gates.md:789`. Verified with `grep -n` and `sed -n`. Line counts in this note were not re-measured.

+    > **Decided and done (2026-09-16):** see commit `4de5b6b` on `docs/simplification-audit`. The human took the deferred decision: remove the mechanism. Deleted `.pre-commit-hooks.yaml` (31 lines), `scripts/check-release-needed.sh` (242), `tests/test-check-release-needed.sh` (449 at HEAD, not the 442 above) and `tests/test-vale-hooks-consumer.sh` (276 at HEAD, not 272), plus the `check-release-needed` hook block, for **1,443 lines removed and 234 added** across 20 files. ADR-0014 is **amended, not retired**, as the note above says: its runtime bundling decision stands, and the amendment records why the export went and keeps the `entry[0]`-only constraint (`LESSONS.md:101,105`) in case it returns. ADR-0025 gets a pointer to that amendment. Tags are left in place. **One cost the finding did not count:** `tests/test-vale-wrap.sh` case 33, the cross-manifest `files:` drift check, and case 28's hook-scope half both read the published manifest and went with it. Case 33's one guard that did not need a second manifest, a local regex narrowed to one plugin, is now a third property of case 32, with its own mutation test, so that coverage is kept. `gates.md` now counts 8 authored pre-push hooks (10 reported), no longer 9 (11).
 
 37. [x] ~~**Two `.mcp.json` files declare an Obsidian vault server over `docs/`** (root and `plugins/bin/`; the other five plugin `.mcp.json` files are empty stubs), while `AGENTS.md` forbids using an external memory system for this repo. If the Obsidian tools are unused, drop both and the `reinject_mcp_servers` explanation in the bin README; the bin `plugin.json` pair regenerates. Effort S.~~
     > **Not proceeding (2026-09-13):** premise doesn't hold. The server exposes the repo's own git-tracked `docs/` folder — not an external/off-repo store — so it isn't the "external memory system" AGENTS.md's rule targets. It was deliberately added and versioned (3 commits), is documented as current intended behavior in both READMEs, and ADR-0018 uses it as its only concrete worked example of apm's MCP-dependency propagation mechanism actually working. No skill invokes the Obsidian tools as a workflow step, but that alone doesn't make the config dead. No changes made; recommend a human confirm whether the vault tooling is still wanted before removing it.

The mechanism is additionally **already broken** (a consumer pinning `rev: v2.0.1` gets a stale `skill-size-check.sh`, and the guard cannot fire through Gitea's merge button).
