KIEU STORY AI CINEMA — TIER 5 ADVERSARIAL COVERAGE HARDENING (CHALLENGER 1)
=============================================================================
Test Suite: test_tier5_creative_hardening.py
Scope: Features F1 through F7 (Creative, Directives, Screenplay & Prompts)
Agent: teamwork_preview_challenger (Tier 5 Challenger 1 - Creative & Directives)

Adversarial Stress Verification Targets:
- F1: EP01 Screenplay & Pacing Expansion (188 shots, 15 scenes C01-C15, 3-Act structure)
- F2: Đạm Tiên Grave 3-Beat Sequence (C05-A/B/C, 27 shots, anti-premature-weeping)
- F3: Anti-Male-Tears Script Purge (0% male crying, feudal stoicism across 188 shots)
- F4: Character & Acting Directives in Bibles (Kiều-Vân 4-axis twin, pure East Asian Sai Nha)
- F5: 2-Step Sweet-Spot Start Frame Protocol (Gemini Banana 720p, zero reverse physics)
- F6: Lip-Sync & Off-Screen Dialogue Guard (Mandatory closed-lips on off-screen/VO)
- F7: EP01 188-Shot AI Prompt Registry Consistency & Asset Integrity

Empirical Gap Discovery Objectives:
1. Audit Thúy Vân age & twin status consistency across bibles, screenplay, and prompts.
2. Audit filesystem integrity for all 83 character_asset_ref paths in Muse prompts.
3. Audit production orchestrator start-frame resolution fallback vulnerability.
