@@ -259,9 +259,10 @@ several "obvious" merges turned out to hide debt and are **not** clean drop-ins.
 - **`check:docs-sync` runs twice** — standalone in the `lint` job and again inside `check:docs-all` (`docs-sync-strict`) and the husky pre-commit hook. ✅ **DONE** — standalone `lint` invocation removed.
 - **CVE scanning** — ❌ **NOT a clean merge.** `audit:deps` hard-fails on any high/critical CVE; `check:vuln-ratchet` (osv) only fails on a _regression_ vs baseline (currently 1 MODERATE). Different semantics — dropping `audit:deps` would lose the absolute high/critical gate. Keep both.
 - **Cycle detection** — ❌ **NOT a clean merge.** `check:circular-deps` (dpdm) reports **91 cycles** (that is why it is advisory); it cannot be promoted to blocking without first resolving them, and it has a broader scope than the green, curated `check:cycles`. Keep `check:cycles` blocking; resolving the 91 dpdm cycles is its own backlog.
-- **Complexity** — ⏳ valid but real surgery. `check:complexity` (core ESLint) + `check:cognitive-complexity` (sonarjs) are two ESLint passes over `src` + `open-sse`; merging into one config emitting both metrics needs careful ratchet re-wiring. Deferred.
-- **`/api` anti-hallucination** — ⏳ valid but script surgery. `check:openapi-routes` (spec→route) + `check:docs-symbols` (prose→route) share resolution logic; collapsing them is a non-trivial script change. Deferred.
+- **Complexity** — ✅ **DONE** (`check:complexity-ratchets` / `eslint.complexity-ratchets.config.mjs`): one ESLint walk, counts by ruleId so cyclomatic+max-lines and cognitive baselines stay independent; individual `check:complexity` / `check:cognitive-complexity` remain for local `--update`.
+- **`/api` anti-hallucination** — ✅ **DONE** (`check:api-docs-refs` + `scripts/check/lib/apiRoutes.mjs`): one FS inventory of `src/app/api`, openapi-routes + docs-symbols still report independently; individuals remain for local runs.
 - **`check:node-runtime` runs in 11 jobs** — ⚠️ **low ROI.** Each is a separate runner and the check is <1s; total savings ~10s, against losing a cheap per-job guard. Not worth the churn.
+- **`typecheck:noimplicit:core` on CI lint** — ✅ **removed from lint job** (was advisory `continue-on-error`); blocking type surface is `typecheck:core` + `check:type-coverage`. Local script retained.
