|
## Status: PASS
|

|
|
|
||
|
|
## Artifacts reviewed
|
||
|
|
|
||
|
|
- `SPEC.md` — R1-R5 + D-V1 to D-V5; 13-item test plan
|
||
|
|
- `IMPLEMENTATION.md` — files touched, decisions locked, inline bug found and fixed, tests enumerated
|
||
|
|
- `CODE_REVIEW.md` — SPEC coverage table, defensive correctness check, cross-script impact, spot-check, PASS verdict
|
||
|
|
- `BUG_REPORT.md` — O1-O4 observations; all non-blocking; documented behaviors per SPEC
|
||
|
|
- `ADVERSARIAL_BUG_REPORT.md` — A1-A8 sweep; no blockers; documented behaviors per SPEC
|
||
|
|
- `DOC_REVIEW.md` — docs touched: technical.md §7, functional.md §10, CHANGELOG.md; AGENTS/README/prompt intentionally untouched; cross-references confirmed

## Final acceptance criteria
|
||
|
|
|
||
|
|
1. **R1 (pass string coercion)**: ✓ three-way dispatch; `"true"`→True, `"false"`→False, others→`bool(...)`.
|
||
|
|
2. **R2 (score clamp [0,1])**: ✓ `max(0.0, min(1.0, score))`.
|
||
|
|
3. **R3 (non-numeric score → 0.5)**: ✓ `try/except (TypeError, ValueError)`.
|
||
|
|
4. **R4 (backwards compat)**: ✓ strict emitters unaffected; tested.
|
||
|
|
5. **R5 (no new deps)**: ✓ `math` stdlib only.
|
||
|
|
6. **Tests pass**: ✓ 469 passed (447 baseline + 22 new; 0 regressions).
|
||
|
|
7. **Docs in sync**: ✓ technical.md §7 + functional.md §10 + CHANGELOG.md updated.

## Inline bug found during implementation
|
||
|
|
|
||
|
|
The first iteration of the three-way branch set `verdict_pass = (raw_pass.strip().lower() == "true")`, mapping every non-`"true"` string to False. SPEC R1's `bool(...)` fallback clause was violated (`"yes"` would have regressed from True to False). The implementer caught this via `test_other_truthy_string_pass` before running the full suite, fixed the branch to explicit `if/elif/else: bool(...)`, and the test now guards the contract.
|
||
|
|
|
||
|
|
This is exactly the failure mode the phase pipeline is designed to surface: test-driven discovery of SPEC non-conformance during implement, not after deploy.
|
||
|
|
|
||
|
|
## Adversarial highlights
|
||
|
|
|
||
|
|
- `pass: null`/`[]`/`{}`/`0` → False, `pass: [false]` → True (Python truthy non-empty list). All match v1 `bool(...)` semantics; no regression.
|
||
|
|
- `score: NaN`/`Infinity`/`-Infinity` literals (json.loads accepts) → 0.5 via `math.isfinite`. Confirmed.
|
||
|
|
- `score: "2.0"` (out-of-range numeric string) → clamped to 1.0. The clamp fires after the try/except float() parse, so numeric strings are clamped too. Confirmed.
|
||
|
|
- `score: true` / `score: false` (JSON bool) → 1.0 / 0.0 via `float(True)` / `float(False)`. Documented quirk; downstream plateau gate handles consistently.
|
||
|
|
|
||
|
|
## Verdict
|
||
|
|
|
||
|
|
PASS — task is complete; all artifacts present; all phase gates satisfied; no blockers; no outstanding follow-ups for this task. The score-clamping improvement to plateau detection (BUG_REPORT.md O3) is a positive side effect noted in the CHANGELOG.

Approve transition to complete.
