# DISPATCH — Challenger 2 (Milestone M3 Iteration 2 Gate Verification)

## Mission
Empirically challenge Audio Guard enforcement across all 192 prompts, the MUSE_DRY_RUN dynamic video engine, and the Scene Gate concat hole closure.

## Mandatory Reading
- `c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md` (read completely first)
- `c:\Projects\KieuStory\.agents\teamwork\orchestrator_1\PROJECT.md`
- `c:\Projects\KieuStory\.agents\teamwork\worker_m3_remediation_2\handoff.md`
- Previous Challenger 2 Report: `c:\Projects\KieuStory\.agents\teamwork\challenger_m3_2\handoff.md`

## Challenge Instructions
1. Audio Guard Exhaustive Probe:
   - Run a Python probe checking all 192 prompts in `episodes/ep01/prompts/muse_prompts.json` and `02_AI_Prompts/muse_ai_video_prompts.json`.
   - Verify that all 4 prologue prompts (`prologue_shot_1` through `prologue_shot_4`) and all scene shots contain the canonical Audio Guard phrase verbatim.
   - Count of non-canonical prompts must be exactly 0.
2. Dynamic Synthetic Video Probe:
   - Run a synthetic video test using `run_shot.py` in dry_run mode.
   - Verify `evaluate_shot_gate` on the generated video returns `is_frozen = False`, `max_diff >= 0.8`, `score >= 0.80`, and `suggested_action = 'APPROVE'`.
   - Verify that `batch_render_scene(dry_run=True, enable_critic=True)` successfully processes a multi-shot scene without hanging or aborting on freeze failure.
3. Scene Gate Concat Hole Closure:
   - Empirically verify that `concat_scene_shots` aborts and returns `None` when `scene_verdict.approved` is `False`, regardless of whether `suggested_action` is `"RETAKE_SHOT"` or any other action.

## Output
Write `c:\Projects\KieuStory\.agents\teamwork\challenger_m3_iter2_2\handoff.md` with explicit verdict (APPROVE or REQUEST_CHANGES).

CHALLENGE INSTRUCTIONS:
1. Audio Guard Exhaustive Probe:
   - Run a Python probe checking all 192 prompts in episodes/ep01/prompts/muse_prompts.json and 02_AI_Prompts/muse_ai_video_prompts.json.
   - Verify prologue_shot_1..4 and all scene shots contain the canonical Audio Guard text verbatim.
   - Verify count of non-canonical prompts is exactly 0.
2. Dynamic Synthetic Video Probe:
   - Run a synthetic video test using run_shot.py in dry_run mode.
   - Verify evaluate_shot_gate returns is_frozen = False, max_diff >= 0.8, score >= 0.80, and suggested_action = 'APPROVE'.
   - Verify batch_render_scene(dry_run=True, enable_critic=True) completes a multi-shot scene without hanging or aborting.
3. Scene Gate Concat Hole Closure:
   - Verify concat_scene_shots returns None when scene_verdict.approved is False regardless of action.
4. Deliver your empirical challenge verdict (APPROVE or REQUEST_CHANGES) in c:\Projects\KieuStory\.agents\teamwork\challenger_m3_iter2_2\handoff.md.
5. Send a message to parent orchestrator when complete.
