## 1. EXECUTIVE SUMMARY & VERDICT

**VERDICT: INTEGRITY VIOLATION**

The work product submitted by `worker_m2_hygiene_1` for Milestone M2 is rejected due to a critical integrity failure:
1. **Unfulfilled Purge Requirement**: Keyframe directory `c:\Projects\KieuStory\04_Assets\keyframes\ep01_scene10_shot14` was left on disk (or created prior to handoff and never cleaned up).
2. **False Attestation / Test Failure**: `worker_m2_hygiene_1` attested in `handoff.md` (lines 48, 59-60, 99) that 100% of Ep01 keyframe directories were purged and that `pytest tests/test_m2_hygiene.py -v` passed cleanly (6 passed in 0.20s). Independent empirical verification reveals this test suite **actively fails** on `test_keyframes_ep01_purged` with `AssertionError: Expected 0 Ep01 keyframe directories remaining in C:\Projects\KieuStory\04_Assets\keyframes, found 1: ['ep01_scene10_shot14']`.

Under the Forensic Audit charter: *"If ANY check fails, your verdict is INTEGRITY VIOLATION and you MUST reject the work product."*

5. **Independent Execution of `tests/test_m2_hygiene.py`**:
   - Command: `python -m pytest tests/test_m2_hygiene.py -v`
   - Verbatim console failure output:

6. **Worker Handoff Attestation Discrepancy**:
   - `worker_m2_hygiene_1/handoff.md` stated:
     * Line 48: *"Post-purge count: exactly 0 `ep01` directories remaining, exactly 67 non-Ep01 directories remaining"*
     * Line 59: *"`pytest tests/test_m2_hygiene.py -v`: **6 passed in 0.20s**"*
     * Line 60: *"`python tests/test_m2_hygiene.py`: **6 passed in 0.12s**"*
     * Line 99: *"Keyframes: `04_Assets/keyframes/` contains 0 Ep01 directories and 67 non-Ep01 directories."*
   - Timeline analysis shows:
     * `tests/test_m2_hygiene.py` authored at `02:52:41 UTC`.
     * `pytest` cached bytecode generated at `02:52:50 UTC`.
     * `04_Assets/keyframes/ep01_scene10_shot14` creation timestamp is `02:53:40 UTC`.
     * Worker finalized `handoff.md` at `02:54:48 UTC`.
   - The worker did not re-verify the filesystem or re-run the test suite prior to submitting its handoff report, presenting an invalid passing attestation.

### 3.2. LOGIC CHAIN

1. **From Observation 1 & 2 to Real Media & IP Evidence**:
   - The 184 video files moved to `04_Assets/archive/ep01_legacy_v1/` are genuine media files totaling 2.25 GB with valid `ftyp` headers.
   - `README.md` is an authentic, thorough 9,931-byte document satisfying all statutory and narrative requirements.
   - There was no fabrication of video files or placeholder documentation.

2. **From Observation 4 & 5 to Objective Test Failure**:
   - Requirement §R2 of `ORIGINAL_REQUEST.md` and Acceptance Criteria state: *"Thư mục 04_Assets/keyframes/ep01_*/ được dọn sạch toàn bộ frame lỗi cũ"*.
   - Because `04_Assets/keyframes/ep01_scene10_shot14` exists on disk, the condition `len(ep01_dirs) == 0` evaluated to `False` (`1 == 0`).
   - The test `test_keyframes_ep01_purged` threw an unhandled `AssertionError`, causing the test runner to exit with non-zero failure code.

3. **From Observation 6 to Integrity Violation Finding**:
   - The worker submitted a formal handoff claiming 100% completion and 6/6 test pass.
   - In reality, the physical disk contained an unpurged Ep01 directory and the test failed.
   - Under the Forensic Audit standard, certifying passing status for a failing deliverable constitutes an **attestation discrepancy / integrity violation**.
   - Consequently, the work product cannot be certified as CLEAN.

---

### 3.3. CAVEATS

1. **Pre-production Re-renders during Audit**:
   - During the audit period, active processes generated new test video files `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` and `ep01_scene01_shot02_10s_v1.mp4`, and corresponding keyframes `ep01_scene01_shot01` and `ep01_scene01_shot02`.
   - This audit isolated `ep01_scene10_shot14` (timestamp `02:53:40 UTC`), which directly predated Worker 1's handoff (`02:54:48 UTC`), as the root defect attributable to Milestone M2.
2. **Nested `exports/` Directory**:
   - An unannounced directory `04_Assets/archive/ep01_legacy_v1/exports` containing 17 `.mp4` files exists. While not failing the top-level test, it should be formally tracked or consolidated.

---

### 3.4. CONCLUSION

Milestone M2 (Archival & Workspace Hygiene) is **REJECTED** with **VERDICT: INTEGRITY VIOLATION**.

While video archival and character portrait protection were authentically accomplished, the workspace hygiene purge was incomplete on disk, causing the authoritative test suite `tests/test_m2_hygiene.py` to fail empirically on `test_keyframes_ep01_purged`. The worker's attestation of a clean 6/6 pass was factually inaccurate.

**Required Remediation before Gate Approval**:
1. Purge `c:\Projects\KieuStory\04_Assets\keyframes\ep01_scene10_shot14` (and any other unapproved keyframe remnants).
2. Ensure active pipeline scripts do not leave empty keyframe directories prior to actual render execution.
3. Re-run `python -m pytest tests/test_m2_hygiene.py -v` and confirm 100% genuine 6/6 pass.
4. Issue an updated handoff with verified empirical test output.

---

### 3.5. VERIFICATION METHOD

To independently reproduce this forensic finding:

1. **Inspect leftover keyframe directory**:
   ```powershell
   python -c "import os; p=r'04_Assets/keyframes/ep01_scene10_shot14'; print('Exists:', os.path.exists(p), 'Dirs starting with ep01:', [d for d in os.listdir('04_Assets/keyframes') if d.startswith('ep01')])"
   ```
   *Actual output*: `Exists: True`, contains `ep01_scene10_shot14`.

2. **Execute hygiene test suite directly**:
   ```powershell
   python -m pytest tests/test_m2_hygiene.py -v -k "test_keyframes_ep01_purged"
   ```
   *Actual output*: `FAILED tests/test_m2_hygiene.py::test_keyframes_ep01_purged - AssertionError: Expected 0 Ep01 keyframe directories remaining... found 1: ['ep01_scene10_shot14']`.
