# BRIEFING — 2026-10-09T02:44:30Z

## Mission
Conduct an in-depth survey of the pipeline codebase and critic architecture for the Ep01 Re-production Campaign of 'Thập Ngũ Niên'.

## 🔒 My Identity
- Archetype: Explorer
- Roles: Read-only investigation, pipeline analysis, critic architecture design & synthesis
- Working directory: c:\Projects\KieuStory\.agents\teamwork\explorer_survey_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: Ep01 Re-production Campaign - Pipeline & Critic Architecture Survey

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Strictly adhere to AGENTS.md, GEMINI.md, ORIGINAL_REQUEST.md
- Follow Anti-dilution / Project Isolation guidelines (project='KieuStory')

## Investigation State
- **Explored paths**:
  - `c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md`
  - `AGENTS.md` and `GEMINI.md`
  - `05_Production_Pipeline/` (`production_orchestrator.py`, `multi_worker_orchestrator.py`, `episode_manager.py`, `audio_continuity_engine.py`, `pipeline_helper.py`, `run_shot.py`, `continuity_checker.py`)
  - `02_AI_Prompts/gemini_banana_prompts.json` & `muse_ai_video_prompts.json`
  - `episodes/ep01/prompts/muse_prompts.json` & `banana_prompts.json`
  - `00_Project_Bible/` (`CHARACTER_BIBLE.md`, `FUTURE_SOFTWARE_PLAN_AUTONOMOUS_CINEMA.md`)
  - `FilmMaker/TAP_01_XUAN_SAC_THE_NGUYEN_VA_GIONG_BAO_DOAN_TRUONG.md`
  - `04_Assets/characters/`, `04_Assets/keyframes/`, `04_Assets/videos/`, `04_Assets/archive/`
  - Python runtime environment (`pydantic` 2.13.5, `google.antigravity`, `google.genai`, `cv2`, `GEMINI_API_KEY`)
- **Key findings**:
  - Root cause of character morphing ("nhiễm Thúy Kiều"): blind `shot_num > 1 -> prev_tail` logic in `resolve_start_frame` of `production_orchestrator.py`.
  - Defined deterministic classification for `Cinematic Cut` vs `Continuous Take` using `character_anchor` in `gemini_banana_prompts.json`.
  - Architecture of R1 2-Tier Quality Gate fully designed in `antigravity_critic_gate.py` with Pydantic v2 `VideoCriticVerdict`.
  - Dual-engine strategy: Google Antigravity SDK (`Agent`, `LocalAgentConfig`, `Video`, `Image`) + `google.genai.Client` + rule-based offline fallback.
  - Threshold rule: `score >= 0.8` for acceptance.
- **Unexplored areas**: None for this survey scope. Architecture is fully mapped out and ready for implementation.

## Key Decisions Made
- Confirmed placement of critic module: `05_Production_Pipeline/antigravity_critic_gate.py`.
- Formulated `VideoCriticVerdict` with 6 detailed sub-models covering Shot Gate (character validation, visual quality, audio guard) and Scene Gate (junctions, 180-degree rule, eyeline, color continuity, editing tempo, trims).
- Established `resolve_start_frame_v2` logic to strictly prevent tail frame inheritance on Cinematic Cuts.
