-- [ ] Verification output is real (re-run if suspicious)
-- [ ] No backward-incompat surprises
-- [ ] Tests cover the new behavior
+- [x] ARCHITECTURE.md test coverage table accurate (counts re-verified)
+- [x] DESIGN.md updated
+- [x] TASKS.md baseline references updated
+- [ ] **Three stale references still live** — see notes.

+### Reviewer notes (2026-05-11) — Changes Requested
+
+Updates in `ARCHITECTURE.md`, `DESIGN.md`, and `TASKS.md` are correct. Per-crate breakdown matches the actual counts. Three lines were missed:
+
+```
+docs/PRD/PRD-wire-format-v2.md:22   - All 272 audio tests pass under v2.
+docs/PRD/PRD-wire-format-v2.md:102  - All 272 audio tests pass with v2 headers.
+docs/ROAD-TO-VIDEO.md:96            - All 272 audio tests pass with `V=2` headers.
+```
+
+The grep pattern in step 1 of the task block (`"272 tests\|272 pass\|272 total"`) was too narrow — it doesn't match `272 audio tests`. Replace all three lines with the current non-Android baseline.
+
+A broader grep would have caught these:
+
+```bash
+grep -rn "272" docs/ | grep -v -E "T1\.1\.[12]-report|_example|line 272|/272[/-]" | grep -i "tests\|audio"
+```
+
+Use that when re-running. Confirm zero matches after the fix.
+
+**Important precedent (same lesson as T1.1.1):** the `Done when` line is the contract, not the literal `Verify` command. When a spec provides a verify command narrower than the `Done when`, re-derive a check from the `Done when` and add it. Here `Done when` said "No doc references the stale 272 figure" — that's broader than the grep given. Confirming the broader criterion is the agent's job.
+
+**Rework:** edit the three lines, append a `## Rework — <UTC>` section to this report per `reports/README.md`, then move status back to `Pending Review`.
+
+## Rework (2026-05-11T07:25Z)
+
+Addressed reviewer feedback:
+
+- Fixed three missed references:
+  - `docs/PRD/PRD-wire-format-v2.md:22` — "272 audio tests" → "571 audio tests"
+  - `docs/PRD/PRD-wire-format-v2.md:102` — "272 audio tests" → "571 audio tests"
+  - `docs/ROAD-TO-VIDEO.md:96` — "272 audio tests" → "571 audio tests"
+- Re-ran broader verification per reviewer suggestion:
+  ```bash
+  grep -rn "272" docs/ | grep -v -E "T1\.1\.[12]-report|_example|line 272|/272[/-]" | grep -i "tests\|audio"
+  ```
+  → Only matches are the task-description lines themselves (not stale references).
+
+**Status moved back to Pending Review.**
