# Progress — Forensic Auditor (Milestone M4 Gate Integrity Verification)

- **Status**: Completed (Verdict Rendered)
- **Last visited**: 2026-10-09T08:24:00Z
- **Current task**: Forensic verification of M4 deliverables complete

## Step-by-Step Execution Plan:
1. [x] Step 1: Initialize DISPATCH.md and BRIEFING.md
2. [x] Step 2: Read ORIGINAL_REQUEST.md, PROJECT.md, worker_m4_assembly_1/handoff.md
3. [x] Step 3: Forensic Inspection of Source Code Authenticity:
   - `05_Production_Pipeline/production_orchestrator.py`: `resolve_audio_asset`, `resolve_scene_master`, `concat_scene_shots` Mode A default, `assemble_episode_master` verified genuine.
   - `05_Production_Pipeline/assemble_ep01_feature.py`: `_master_audio` detection, `--scenes 10` verified genuine.
   - OpenCV check: verified 0 `cv2.VideoWriter` in concat routines.
   - DEFECT DISCOVERED: Line 1170 `ffmpeg_exe.replace("ffmpeg", "ffprobe")` breaks executable path on Windows.
4. [x] Step 4: Forensic Inspection of Test Suite Authenticity:
   - `tests/test_production_pipeline_m4.py`: verified tests run against real physical media files generated via FFmpeg/lavfi, unmocked pipeline logic.
5. [x] Step 5: Independent Test Execution:
   - `python -m pytest tests/test_production_pipeline_m4.py -v`: 15/15 PASSED (10.13s)
   - `python -m pytest tests/test_production_pipeline_m3.py -v`: 16/16 PASSED (6.53s)
   - `python -m pytest tests/test_adversarial_m3_audio_engine.py -v`: 6/6 PASSED (29.52s)
   - `python -m pytest tests/test_critic_gate.py -v`: 30/30 PASSED (13.49s)
   - `python -m pytest tests/test_tier5_pipeline_hardening.py -v`: 20/20 PASSED (4.69s)
   - `python -m pytest tests/test_m2_hygiene.py -v`: 1 FAILED, 5 PASSED (0.31s) -> VIOLATION
6. [x] Step 6: Asset Integrity & Legacy Archive Verification:
   - `04_Assets/archive/ep01_legacy_v1/`: 185 items intact and unhampered.
   - `04_Assets/characters/`: exactly 62 files tracked in git, but 40 untracked turnaround files present on disk -> VIOLATION
7. [x] Step 7: Integrity Forensics Search:
   - Searched for hardcoded strings/test IDs, dummy facades, mocked passes.
8. [x] Step 8: Author forensic handoff report (`handoff.md`) with Binary Verdict: VERDICT: INTEGRITY VIOLATION.
9. [ ] Step 9: Send notification to orchestrator.
