Note: contract value "1w ago" is impossible to produce — weeks start at ≥30d, so minimum is 4w. Test correctly demonstrates week-level precision with a reachable value. |

## Independent Findings

**Prediction resolution:**

1. **Anchor I/O leak in matrix path** — Not found. The `--matrix` path (proof.ts:1637-1788) uses its own loop that never calls `fs.existsSync` or `fs.readFileSync`. Clean separation.
2. **recent_entries finding_count counting wrong source** — Not found. Code counts current active findings per entry slug during the same filtered iteration (proof.ts:1693).
3. **formatRelativeTime edge cases** — Confirmed. Invalid ISO strings produce `NaN` → `"NaNw ago"`. Future dates produce negative diff → hours < 1 → `"<1h ago"` regardless of how far in the future. No caller validation.
4. **Template sync divergence** — Not found. `diff` confirms byte-for-byte identical output.
5. **Cross-tab filter test weakness** — Not found. Test iterates all keys and asserts each matches `/^risk\//` — strong verification.

**Surprise:** Contract A027 specifies value "1w ago" but the implementation makes this output impossible (weeks start at ≥30 days, minimum week value is 4w). The test correctly uses a reachable value ("5w ago") instead.

## AC Walkthrough

- [x] AC1: `by_severity_action` in JSON output — ✅ PASS. Verified via test (proof.test.ts:4358) and code inspection (proof.ts:1962). Field added to JSON envelope.
- [x] AC2: Human-readable cross-tab line — ✅ PASS. Verified via test (proof.test.ts:4389-4391) and code (proof.ts:1986-1996). Cross-tab displayed after severity line with ` · ` separators.
- [x] AC3: `--matrix` returns only orientation data — ✅ PASS. Verified via test (proof.test.ts:4405-4411). No `by_file`, all orientation fields present.
- [x] AC4: `--matrix --json` envelope shape — ✅ PASS. Verified via test. `recent_entries` includes slug, result, finding_count, completed_at, ago.
- [x] AC5: `--matrix` human-readable orientation block — ✅ PASS. Verified via test (proof.test.ts:4465-4469). Shows header, staleness, recent proofs.
- [x] AC6: `--matrix` skips anchor I/O — ✅ PASS. Code inspection: matrix path (proof.ts:1637-1788) has no fs.existsSync/readFileSync calls. Separate loop from standard audit path.
- [x] AC7: `--matrix` ignores filters — ✅ PASS. Verified via tests (proof.test.ts:4487, 4497). Matrix early-returns before filter application.
- [x] AC8: 0 findings edge case — ✅ PASS. Verified via test (proof.test.ts:4512-4529). Returns zeros and includes recent_entries.
- [x] AC9: 0 entries edge case — ✅ PASS. Verified via test (proof.test.ts:4534-4539). Returns "no proof chain data".
- [x] AC10: Template update — ✅ PASS. Both template and dogfood updated, byte-for-byte identical. Contains `--matrix` instruction and three-option menu.
- [x] AC11: `--matrix` without `--json` omits file list — ✅ PASS. Verified via test (proof.test.ts:4543-4548).
- [x] AC12: Cross-tab respects filters in standard mode — ✅ PASS. Verified via test (proof.test.ts:4553-4563). All keys match `/^risk\//` when `--severity risk` applied.
- [x] AC13: Tests pass — ✅ PASS. 2458 passed, 0 failed, 2 skipped (pre-existing).
- [x] AC14: No build errors — ✅ PASS. Clean typecheck + tsup.

## Blockers

No blockers. All 29 contract assertions satisfied, all 14 ACs pass. Tests pass, build clean, lint clean (pre-existing warning only). Checked for: unused exports in new code (formatRelativeTime is imported in proof.ts and used), unused parameters (none), error paths without tests (formatRelativeTime invalid input — noted in findings but not a blocker), dead code paths (none — every branch in matrix path is exercised by tests).

## Findings

- **Code — formatRelativeTime doesn't handle invalid input:** `packages/cli/src/utils/proofSummary.ts:2320` — passing an invalid ISO string produces `"NaNw ago"`. No caller currently passes invalid data (all call sites use `entry.completed_at` from parsed chain JSON), so this is latent, not active. Future dates return `"<1h ago"` due to negative diff falling through all comparisons.

- **Upstream — Contract A027 value unreachable:** Contract specifies `value: "1w ago"` but the implementation's 30-day threshold for weeks means the minimum week output is `"4w ago"`. The test correctly uses `"5w ago"` (35 days). Update contract value on next seal to match implementation behavior.

- **Upstream — Contract A003 fixture assumption:** Contract specifies `value: 2` for `risk/scope`, but the test fixture (`createAuditChain(6, 3)`) produces `risk/scope = 1`. The test correctly verifies counts match the distribution — the contract assumed different test data. Update contract value on next seal.

- **Upstream — Contract A029 case mismatch:** Contract specifies `value: "cleanup"` (lowercase) but template uses "Cleanup" (capital C). The test correctly asserts `'Cleanup'`. The intent is met — this is a case convention issue in the contract value.

- **Code — Duplicated zero-entry/zero-chain payloads:** `packages/cli/src/commands/proof.ts:1598-1621` and `packages/cli/src/commands/proof.ts:1638-1656` — the JSON payload for "no proof chain file" and "empty entries array" is identical (same object literal repeated). Could extract to a shared constant. Not a bug — duplication is manageable at two instances.

- **Test — A008/A009 existence-only assertions:** `packages/cli/tests/commands/proof.test.ts:4408-4409` — `stale_count` and `recent_entries` checked with `toBeDefined()` rather than specific values. These are weak per testing standards ("assert on specific expected values"). The fixture has known data — stale_count should be assertable. However, staleness depends on date computation relative to Date.now(), making exact values time-dependent. The existence check is defensible here.

- **Code — proofSummary.ts approaching comfort threshold:** `packages/cli/src/utils/proofSummary.ts` — now ~2330 lines. Active proof chain finding (v1-code-changes-C3) already notes this at ~1550 lines. The 20-line addition is minimal, but the file continues growing. Still present — see v1-code-changes-C3.

## Deployer Handoff

Clean additive feature. The `--matrix` flag adds a new code path that early-returns before the existing audit logic — no risk to existing behavior. Template changes replace two sections in ana-learn.md; verify by reading the diff that section boundaries are correct (sections 2 and 4 replaced, sections 1, 3, 5+ unchanged).

The lint warning about unused eslint-disable in git-operations.ts is pre-existing (not introduced by this build).

Test count increased from baseline 2429 to 2458 (+29 new tests). No test files added — all new tests in existing proof.test.ts.

## Verdict

**Shippable:** YES

All 29 contract assertions satisfied. All 14 acceptance criteria pass. Tests green, build clean, templates synced. The implementation is well-structured — matrix path cleanly separates from standard audit with an early return, avoids file I/O as specified, and handles both edge cases (0 findings, 0 entries). Findings are upstream contract issues and minor code observations — nothing that prevents shipping.
