You are Explorer 1 for Milestone M1 Iteration 2 (Critic Gate Remediation).

Your working directory is: c:\Projects\KieuStory\.agents\teamwork\explorer_m1_remediation_1

MANDATORY FIRST STEP:
Read c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md completely. Do not skip this.
Read c:\Projects\KieuStory\.agents\teamwork\orchestrator_1\PROJECT.md.

MANDATORY AUDIT & REVIEW EVIDENCE:
You must read the full handoff reports from Iteration 1 Gate:
- Reviewer 1 Report: c:\Projects\KieuStory\.agents\teamwork\reviewer_m1_1\handoff.md
- Challenger 1 Report: c:\Projects\KieuStory\.agents\teamwork\challenger_m1_1\handoff.md
- Auditor Report: c:\Projects\KieuStory\.agents\teamwork\auditor_m1_1\handoff.md

SPECIFIC DEFECTS TO INVESTIGATE & REMEDIATE IN 05_Production_Pipeline/antigravity_critic_gate.py:
1. MLLM Multimodal Facade:
   - In GoogleGenAIEngine (lines 664-724) and AntigravitySDKEngine (lines 629-662): media (keyframes/video) was never bound to contents, creating a text-only prompt that hallucinates visual scores.
   - Design the exact, robust fix: Extract keyframes from the video using OpenCV, convert to JPEG/PNG bytes, and attach as image Parts (e.g. genai.types.Part.from_bytes or PIL image) to Gemini contents, OR if running in offline mode without API key, cleanly delegate to OfflineHeuristicEngine without pretending to query Gemini.
2. Scene Gate False-Positive Approval on Missing/Corrupt Files:
   - evaluate_scene_gate (lines 451-458, 516-540) silently catches errors on non-existent or corrupted files with continue and defaults empty junction_scores / color_diffs to 0.95 and APPROVE!
   - Design upfront validation: verify that all video files in shot_video_paths exist, are non-empty, and can be opened with cv2.VideoCapture. If any file fails, immediately return overall_score=0.0, approved=False, suggested_action="RETAKE_SHOT", critique_notes detailing which files were missing/corrupt.
3. Frozen / Defective Video Approval Leak:
   - In evaluate_shot_gate, a frozen video or single visual defect docks only 0.15, leaving score at 0.85 and approved=True.
   - Design strict penalty and action override: if frozen video, black frames, or severe defects are detected, ensure overall_score is docked below 0.8 (e.g. min 0.35 dock or score <= 0.65), approved=False, and suggested_action="RETAKE_SHOT".
4. Dead Code & Incomplete Character Cross-Contamination:
   - _find_character_portrait is defined but never called. Only Kim Trọng is checked, allowing Thúy Kiều to pass as Vương Ông với score 1.0!
   - Design wiring of _find_character_portrait in evaluate_shot: for any expected character, load their canonical portrait and cross-correlate against sampled frames; if correlation with Thúy Kiều is high (>0.85) while correlation with the expected character is low (<0.6), flag as character cross-contamination defect.
5. Audio Stream Inspection:
   - _check_audio_stream queries ffprobe as JSON but ignores stdout. Parse json.loads(res.stdout) to verify presence of audio stream and valid codec.

OUTPUT REQUIREMENTS:
- Write your detailed remediation analysis and exact code patches to:
  c:\Projects\KieuStory\.agents\teamwork\explorer_m1_remediation_1\remediation_critic_gate.md
- Write your handoff report to c:\Projects\KieuStory\.agents\teamwork\explorer_m1_remediation_1\handoff.md.
- Send a message to parent orchestrator when complete.
