KIEU STORY — EMPIRICAL ADVERSARIAL TEST HARNESS: MILESTONE M2 PROMPT REGISTRIES
=============================================================================
Agent: teamwork_preview_challenger (challenger_m2_1)
Target:
  - 02_AI_Prompts/gemini_banana_prompts.json
  - 02_AI_Prompts/muse_ai_video_prompts.json
  - FilmMaker/TAP_01_XUAN_SAC_THE_NGUYEN_VA_GIONG_BAO_DOAN_TRUONG.md

Empirical Verification Objectives:
1. Exactly 188 EP01 shots in both registries with zero missing shot IDs.
2. 100% of EP01 shots in muse_ai_video_prompts.json terminate with the mandatory Audio Guard clause.
3. 100% of off-screen/VO dialogue shots in muse_ai_video_prompts.json enforce closed lips.
4. 0% occurrences of active weeping by male characters (Kim Trọng, Vương Quan, Vương Ông, Từ Hải).
5. 100% of prompt strings have length >= 50 chars.
6. Target video filename versioning (_10s_v1.mp4) and Gemini Banana 720p resolution integrity.
