## Mission
Execute Milestone M2: Archival & Workspace Hygiene of 'Thập Ngũ Niên' Ep01 Re-production Campaign without data loss, preserving all invariants and establishing full IP audit trail.

## 🔒 My Identity

- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M2 - Archival & Workspace Hygiene

## 🔒 Key Constraints
- DO NOT CHEAT: Genuine implementation, no hardcoded values or mock facades.
- EXCLUSIVE WRITE OWNERSHIP:
  - c:\Projects\KieuStory\04_Assets\archive\ep01_legacy_v1\
  - c:\Projects\KieuStory\04_Assets\keyframes\ep01_* and c:\Projects\KieuStory\04_Assets\keyframes\ep01_scene03_start_720p.png
  - c:\Projects\KieuStory\tests\test_m2_hygiene.py
  - Local metadata in .agents\teamwork\worker_m2_hygiene_1\
- READ-ONLY: c:\Projects\KieuStory\04_Assets\characters\ (DO NOT MODIFY OR DELETE)
- Protect all non-Ep01 videos and keyframes (ep02-ep06, prologue, standalone).

## Task Summary
- **What to build**:
  1. Invariant baseline check (14 character portraits in 04_Assets/characters/).
  2. Migrate exactly 184 Ep01 legacy videos to 04_Assets/archive/ep01_legacy_v1/.
  3. Create legal and creative justification README.md in archive directory.
  4. Purge exactly 155 Ep01 keyframe directories and 1 root keyframe file.
  5. Invariant post-check (14 character portraits intact).
  6. Automated test suite in tests/test_m2_hygiene.py verifying all hygiene requirements.
- **Success criteria**: All automated tests pass with pytest / python.
- **Interface contracts**: PROJECT.md and survey_assets_hygiene.md.
- **Code layout**: tests/test_m2_hygiene.py, 04_Assets/archive/ep01_legacy_v1/.

## Key Decisions Made
- Migrated 184 Ep01 video files flat directly into `04_Assets/archive/ep01_legacy_v1/` to satisfy exact file count assertions and flat file lookup.
- Authored comprehensive legal README.md (9,931 bytes) citing Vietnamese IP Law Articles 4(8), 14, 20, 43, Nguyễn Du's Public Domain status, author Nguyễn Sĩ Sơn's credentials, and Human-in-the-Loop creative evidence.
- Purged all 155 `ep01_*` keyframe directories and `ep01_scene03_start_720p.png` root file, eliminating all sources of character facial contamination.
- Maintained 100% integrity of `04_Assets/characters/` (14 core portraits + 48 supporting = 62 total).
- Maintained 100% integrity of non-Ep01 assets (118 videos, 67 keyframe dirs, 10 keyframe root files).
- Created automated test suite `tests/test_m2_hygiene.py` with 6 tests, all passing (0.20s).
