## Current Status
Last visited: 2026-10-09T09:00:15Z (Gate M4 Iteration 2 Verification Team actively verifying)
- [x] Received dispatch instructions and initialized BRIEFING.md & DISPATCH.md
- [x] Phase 0 Survey completed by 3 parallel Explorers:
  - Explorer 1: Pipeline & Critic Architecture (`survey_pipeline_critic.md`)
  - Explorer 2: Assets, Keyframes & Archival Hygiene (`survey_assets_hygiene.md`)
  - Explorer 3: Ep01 Script Breakdown & Prompts (`survey_ep01_production.md`)
- [x] Synthesized survey findings and created `PROJECT.md`.
- [x] Milestone M2: Archival & Workspace Hygiene (COMPLETED & VERIFIED)
  - 184 legacy Ep01 video files safely archived in `04_Assets/archive/ep01_legacy_v1/` (2.25 GB, valid ftyp).
  - Legal IP documentation README.md (9,931 bytes) authored.
  - All keyframe directories and root keyframes purged.
  - All 62 character assets intact.
  - Pipeline scripts hardened against eager directory creation.
  - `tests/test_m2_hygiene.py` passes 6/6 cleanly.
- [x] Milestone M1: 2-Tier Quality Gate & Classifier (`antigravity_critic_gate.py`, `resolve_start_frame_v2`) [DONE]
  - [x] Iteration 1: Worker implemented core critic gate & classifier (23 tests). Gate review surfaced edge cases.
  - [x] Iteration 2: Major remediation (multimodal Parts, frozen dock, upfront scene check, bilateral safeguards, prompt sync).
  - [x] Iteration 3: Surgical safeguards finalization (Thúy Vân Steps C & D, compound anchor precedence, attendant substring order).
  - [x] Unanimous Gate PASS: Reviewer APPROVE, Challenger APPROVE, Auditor CLEAN. 170+ tests passing across all suites.
- [ ] Milestone M3: 10-Scene Production Pipeline & Start Frame Generation [IN_PROGRESS]
  - [x] Explorer 1 (`explorer_m3_1`): Complete audit of 140 shots (105 Cuts, 35 Takes), Critic Gate retake loop design, Audio Guard check.
  - [x] Worker 1 (`worker_m3_pipeline_1`): Implemented 100% Start Frame resolution, Shot Gate retake loop, Scene Gate integration, Audio Guard sync, MUSE_DRY_RUN engine, and `test_production_pipeline_m3.py` (158/158 tests passing).

Handoff delivered.
    - Reviewer 1 (`reviewer_m3_iter3_1`) -> APPROVE (verified dual-bucket sync, classifier logic, defense-in-depth, 427/427 tests passing)
    - Challenger 1 (`challenger_m3_iter3_1`) -> APPROVE (0 actor-switch mismatches across 140 shot transitions, 8 diverse adversarial physical tail frame injections with 0 face leaks)
