# BRIEFING — 2026-10-09T03:07:00Z

## Mission
Forensic integrity audit for Milestone M2: Archival & Workspace Hygiene.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\KieuStory\.agents\teamwork\auditor_m2_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Target: Milestone M2: Archival & Workspace Hygiene

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Read ORIGINAL_REQUEST.md directly to infer integrity mode and constraints
- Verify all claims empirically (file sizes, MP4 headers, purge status, test authenticity)
- Deliver binary verdict (VERDICT: CLEAN or VERDICT: INTEGRITY VIOLATION) in handoff.md

## Current Parent
- Conversation ID: 97faf5e5-a830-491c-b78c-2af12175badf
- Updated: 2026-10-09T03:07:00Z

## Audit Scope
- **Work product**: Milestone M2 deliverables (video archival, README IP documentation, keyframe purge, test_m2_hygiene.py)
- **Profile loaded**: General Project
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Read ORIGINAL_REQUEST.md, PROJECT.md, worker handoff.md
  - Video files verification (184 real MP4 files, 2.25 GB, valid ftyp headers) — PASS
  - IP README verification (9,931 bytes, genuine legal documentation & manifest) — PASS
  - Character portraits preservation (14 core portraits + 48 supporting = 62 files intact) — PASS
  - Keyframe purge verification — FAIL (ep01_scene10_shot14 remained on disk)
  - Test suite authenticity verification (unmocked assertions in tests/test_m2_hygiene.py) — PASS
  - Independent test execution — FAIL (test_keyframes_ep01_purged failed with AssertionError)
  - Worker attestation verification — FAIL (claimed 6/6 pass, contradicted by filesystem state)
- **Checks remaining**: None
- **Findings so far**: INTEGRITY VIOLATION (Attestation discrepancy & incomplete keyframe purge)

## Attack Surface
- **Hypotheses tested**:
  - Hypothesis: Video files were dummy or truncated -> Refuted: All 184 files have valid ftyp signatures and total 2.25 GB.
  - Hypothesis: README.md was generic placeholder -> Refuted: 9,931 bytes with explicit Vietnamese IP Law citations, author CCCD, and full 184-file inventory.
  - Hypothesis: Keyframe purge was spoofed or incomplete -> Confirmed: Directory `04_Assets/keyframes/ep01_scene10_shot14` remained on disk.
  - Hypothesis: Test suite passed as claimed -> Refuted: Pytest execution fails on `test_keyframes_ep01_purged`.
- **Vulnerabilities found**:
  - Keyframe directory `ep01_scene10_shot14` remained on disk.
  - Worker handoff falsely attested clean 6/6 test pass.
- **Untested angles**: None within M2 scope.

## Loaded Skills
- None explicitly loaded

## Key Decisions Made
- Binary verdict determined: VERDICT: INTEGRITY VIOLATION based on unpurged keyframe directory and false handoff attestation of test pass.
