| A017 | Detail JSON still works with a slug                         | ✅ SATISFIED  | test line 316, `expect(json.slug).toBe('stripe-payments')` |

## Independent Findings

**Code quality:** Clean. `formatListTable` is 36 lines, well-structured, follows existing patterns. The `!slug` branch in the action handler is 23 lines with clear separation from detail view. No new dependencies added.

**Pattern compliance:** Table formatting uses chalk + padEnd, matching `work.ts` style. JSON branching follows existing `options.json` pattern. Commander argument changed from `<slug>` to `[slug]` correctly; handler signature updated to `string | undefined`.

**Sort implementation:** Uses `localeCompare` on ISO 8601 strings (line 195), which is correct for lexicographic date comparison. Handles undefined `completed_at` by pushing to end (lines 192-194).

**Error handling in list view:** Corrupt JSON is caught and treated as empty (line 233-235). This is a reasonable defensive choice — the detail view throws on parse errors, but for list view, graceful degradation is appropriate.

**Over-building check:** No over-building detected. The diff adds exactly what the spec requires: `formatListTable` function, `!slug` branch, and nothing else. No unused exports, no extra parameters, no dead code paths. Every `if` branch in the new code serves a purpose (json check, empty check, file exists check, parse error catch).

**Test quality:** 11 new test cases covering all list view scenarios. Tests use the established pattern (temp dir, `createProofChain` helper, `runProof` wrapper, `FORCE_COLOR=0`). Each test is focused on a single behavior. The `undatedEntry` fixture correctly omits `completed_at` for edge case testing.

**Regression safety:** Existing 24 detail view tests remain unchanged and all pass. The Commander argument change from `<slug>` to `[slug]` doesn't break existing tests because they all pass a slug argument.

## AC Walkthrough

- ✅ **AC1:** `ana proof` with no arguments displays table with columns: slug, result, assertion ratio, timestamp — Verified via tests (lines 152-186) and live invocation. Output matches spec mockup exactly.
- ✅ **AC2:** Table rows sorted most-recent-first — Verified via test (lines 191-199), inserts in wrong order and asserts correct output order.
- ✅ **AC3:** Assertion ratio shows `contract.satisfied / contract.total` — Verified in source (proof.ts line 203: `` `${entry.contract.satisfied}/${entry.contract.total}` ``), confirmed by test asserting "20/22", and live output shows "20/22".
- ✅ **AC4:** Missing/empty proof_chain.json outputs "No proofs yet." exit 0 — Verified via tests (lines 216-235) and live invocation on project root (no proof_chain.json).
- ✅ **AC5:** `ana proof --json` outputs full proof_chain.json as JSON — Verified via test (lines 239-253) and live invocation returning `{"entries":[]}`.
- ✅ **AC6:** Detail card behavior unchanged — Verified via test (lines 296-305), existing 24 tests pass, source diff shows no changes to detail view logic.
- ✅ **AC7:** Detail JSON behavior unchanged — Verified via test (lines 308-318), `json.slug` equals expected value.
- ✅ **Tests pass:** 946 tests, 74 files, 0 failures. `pnpm run test -- --run`.
- ✅ **No build errors:** `pnpm run build` succeeds cleanly.
- ✅ **Lint clean:** 0 errors, 17 pre-existing warnings (none in proof.ts or proof.test.ts).

## Blockers

No blockers found. Examined all 289 lines of proof.ts, all 630 lines of proof.test.ts, verified all 19 contract assertions, ran build/test/lint, and performed live invocation of both empty-state and populated-state paths. No regressions detected — baseline was 932 tests, now 946 (14 new tests added, all pass).

## Callouts

1. **Slug truncation for long slugs:** The `padEnd(24)` column width means slugs longer than 24 characters will push subsequent columns right, misaligning the table. The spec notes "slugs are typically 15-30 chars" and "no truncation needed for 80-col terminals." This is acceptable for now but will look odd with a 30+ char slug.

2. **Duplicate `@ana` tag IDs between list and detail tests:** The test file reuses assertion IDs (e.g., `@ana A001` appears on both line 150 for list view and line 322 for detail view). The list view tags (lines 150-281) are the ones that map to this contract. The detail view tags (lines 322+) were from the original proof-command contract. Pre-check correctly identifies coverage. Not a problem, but worth knowing.

3. **Result column alignment with chalk:** The result column uses `entry.result.padEnd(9)` before applying chalk coloring (line 201-202). This is correct — padding the raw string before coloring ensures alignment works. If someone refactors to pad after coloring, alignment will break because chalk escape codes add invisible characters.

4. **Test count discrepancy vs spec estimate:** Spec estimated ~10 new tests (932 → ~942). Actual: 14 new tests (932 → 946). The extra tests are for "Proof History" title assertion and the separate slug/date row assertions. Reasonable — more coverage, not over-building.

## Deployer Handoff

- **What changed:** `ana proof` with no arguments now shows a summary table instead of erroring. `ana proof <slug>` and `ana proof <slug> --json` are unchanged.
- **Commander signature change:** The argument changed from `<slug>` (required) to `[slug]` (optional). This is a user-facing improvement — help text now shows `[slug]` as optional.
- **No new dependencies.** No config changes. No migration needed.
- **Test baseline moved:** 932 → 946 tests across 74 files.

## Verdict
**Shippable:** YES

All 19 contract assertions SATISFIED. All 10 acceptance criteria PASS. 946 tests pass, build clean, lint clean. Live invocation confirms both empty and populated states render correctly. No regressions in existing proof command behavior. Implementation is minimal and follows established patterns.
