## Task Summary
- **What to build**: Full patch of Critic Gate engine and Production Orchestrator; update prompt registries (Scene 10, Scene 06, Scene 05); sync to master; update and run tests.
- **Success criteria**: 100% tests pass on test_critic_gate.py, test_m2_hygiene.py, test_tier1_features.py (not test_render), test_m1_challenger2_probe.py.
- **Interface contracts**: Remediation specs from Explorer 1 and Explorer 2.
- **Code layout**: Production pipeline under 05_Production_Pipeline/, prompts under episodes/ep01/ and 02_AI_Prompts/, tests under tests/.

## Change Tracker
- **Files modified**:
  * `05_Production_Pipeline/antigravity_critic_gate.py`: Implemented Blocks 1-4 remediation (keyframe/junction bytes extraction, severe defect scoring, character contamination detection, upfront scene validation).
  * `05_Production_Pipeline/production_orchestrator.py`: Implemented bilateral & multi-character safeguards, heuristic title/prompt fallback, non-none anchor validation.
  * `episodes/ep01/prompts/muse_prompts.json`: Corrected Scene 10 character refs (Thúy Kiều vs Kim Trọng), Scene 09 Kim Trọng shots, outdoor scenes (Scene 04/05/06) studio portrait isolation.
  * `02_AI_Prompts/gemini_banana_prompts.json`: Updated character anchors for Scene 10, Scene 06, Scene 05, Scene 09.
  * `episodes/ep01/prompts/banana_prompts.json`: Synchronized character anchors with master banana prompts.
  * `02_AI_Prompts/muse_ai_video_prompts.json`: Synced via episode_manager.
  * `tests/test_critic_gate.py`: Added frozen video, cross-contamination, corrupt scene tests, and TestBilateralAndCharacterSafeguards with live data.
  * `tests/test_m1_challenger2_probe.py`: Hardened probe with 0-anomaly and 0-defect assertions.
- **Build status**: PASS (All 142 tests passing across 4 test suites)
- **Pending issues**: None

## Quality Status
- **Build/test result**: PASS (100% across all suites):
  * `tests/test_critic_gate.py`: 30/30 PASSED
  * `tests/test_m2_hygiene.py`: 6/6 PASSED
  * `tests/test_tier1_features.py -k "not test_render"`: 65/65 PASSED
  * `tests/test_m1_challenger2_probe.py`: 41/41 PASSED
- **Lint status**: Clean
- **Tests added/modified**: 4 new tests in `test_critic_gate.py`, replaced fixture with `@classmethod`, hardened 3 tests in `test_m1_challenger2_probe.py`.

## Loaded Skills
- None explicitly requested via skill path.

## Key Decisions Made
- Strictly executed Explorer 1 and Explorer 2 blueprints.
- In `production_orchestrator.py`, added Bilateral Safeguards for `kim_trong`, `thuy_kieu`, `vuong_quan`, `vuong_ong`, `thuy_van` preventing any cross-contamination.
- Enforced outdoor scene isolation in `muse_prompts.json` for Scene 04, 05, 06 per F5.3, relying on `banana_prompts` anchors and dynamic pipeline resolution.
- Updated `ep01_scene09_shot01` anchor to `kim_trong` aligning screenplay, muse prompts, and challenger probe.
