REVIEW INSTRUCTIONS:
1. Review the remediated module c:\Projects\KieuStory\05_Production_Pipeline\antigravity_critic_gate.py:
   - Verify MLLM multimodal media binding: check that _extract_keyframe_bytes and _extract_junction_frame_bytes extract JPEG byte parts and attach them to GoogleGenAIEngine and AntigravitySDKEngine, and verify clean None return in offline environments.
   - Verify evaluate_scene upfront validation: verify that missing, empty, or unopenable video files immediately return score=0.0, approved=False, suggested_action='RETAKE_SHOT'.
   - Verify severe defect penalties in evaluate_shot: verify that frozen video (-0.35), black frame (-0.35), short duration (-0.35), or cross-contamination (-0.50) properly dock score below 0.80 and trigger RETAKE_SHOT.
   - Verify _find_character_portrait is fully wired and performs Thúy Kiều cross-correlation for non-Kiều characters.
   - Verify _check_audio_stream parses json.loads(res.stdout) and verifies valid codecs and channels.
2. Review tests in c:\Projects\KieuStory\tests\test_critic_gate.py.
3. Run the test suite: python -m pytest tests/test_critic_gate.py -v
4. Output your formal review verdict (APPROVE or REQUEST_CHANGES) in c:\Projects\KieuStory\.agents\teamwork\reviewer_m1_iter2_1\handoff.md.
