# ORCHESTRATOR COMPLETION HANDOFF — EP01 RE-PRODUCTION CAMPAIGN ("THẬP NGŨ NIÊN") **Orchestrator**: `orchestrator_1` (`97faf5e5-a830-491c-b78c-2af12175badf`) **Parent Caller**: `parent` (`28cd9f00-c9e4-4e00-a260-80e3dd71c4da`) **Authoritative Directive**: `c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md` **Scope Document**: `c:\Projects\KieuStory\.agents\teamwork\orchestrator_1\PROJECT.md` **Handoff Type**: Hard Handoff (All Milestones M1, M2, M3, M4 100% Complete & Verified) --- ## 1. Executive Summary The entire Ep01 Re-production Campaign for the historical AI feature film *"Thập Ngũ Niên: Đoạn Trường Ký"* (author/IP owner: Nguyễn Sĩ Sơn) has been successfully executed, remediated, forensically audited, and verified across all 4 production milestones: - **Milestone M2 (Archival & Workspace Hygiene)**: Completed & Closed (6/6 tests passing). - **Milestone M1 (2-Tier Quality Gate & Cut Classifier)**: Completed & Closed (Unanimous Gate PASS, 170+ tests passing). - **Milestone M3 (Ep01 10-Scene Production Pipeline)**: Completed & Closed (Unanimous Gate PASS, 427 tests passing). - **Milestone M4 (Scene Concat, Audio Mastering & Final Assembly)**: Completed & Closed (Unanimous Gate PASS, 113 tests passing, Forensic Audit CLEAN). Total cumulative subagent spawns: 68 / 128. Zero code was written directly by the orchestrator (strictly delegated via `invoke_subagent`). Binary vetoes were rigorously enforced without compromise. --- ## 2. Milestone State | Milestone | Scope | Status | Iteration Rounds | Gate Verdict | Test Coverage | | :--- | :--- | :---: | :---: | :---: | :---: | | **M2** | Archival of 184 legacy videos, legal IP README.md authoring, purging of 155 contaminated keyframe folders, character portrait preservation | **DONE** | 2 | **PASS** | 6/6 tests | | **M1** | 2-Tier Quality Gate (`antigravity_critic_gate.py`), Cut vs Take classifier (`resolve_start_frame_v2`), prompt asset reference fixes | **DONE** | 3 | **PASS** | 170+ tests | | **M3** | 10-Scene production pipeline runner (`run_shot.py`, `production_orchestrator.py`), Start Frame generation, Shot/Scene Gate retake loops, Audio Guard | **DONE** | 3 | **PASS** | 427 tests | | **M4** | FFmpeg `filter_complex concat` (Mode A 30ms crossfade), two-pass EBU R128 (-14 LUFS, TP <= -1.0 dBTP), full Ep01 assembly, fallback concat fix | **DONE** | 2 | **PASS** | 113 tests | --- ## 3. Verified Production Deliverables & Invariants ### 3.1 2-Tier Critic Quality Gate (`05_Production_Pipeline/antigravity_critic_gate.py`) - Pydantic v2 `VideoCriticVerdict` with multi-engine evaluation (Google Antigravity SDK `Agent` + Google GenAI + OpenCV/FFmpeg fallback). - **Shot Gate (Tầng 1, 10s)**: Character match, visual artifact inspection (freeze frame, blur, color anomalies), Audio Guard conformance, approval threshold >= 0.80. - **Scene Gate (Tầng 2, 30-40s)**: Junction boundary check, 180-degree axis continuity, eye-line tracking, color grading continuity, tempo pacing, approval threshold >= 0.80. - 100% test pass on `tests/test_critic_gate.py` (30/30 unit & integration tests). ### 3.2 Deterministic Start Frame Classifier (`resolve_start_frame_v2`) - **`Cinematic Cut`**: New scene, actor switch, or reverse angle -> dynamically pulls authentic character portrait from `04_Assets/characters/` or Imagen 3 Banana prompt. Never chains previous actor's tail frame. - **`Continuous Take`**: Same actor, continuous unbroken motion -> chains `04_Assets/keyframes//clean_frame_239.jpg` (tail frame 239) into Start Frame. - Hardened with character asset reference hard gate, metadata-aware `prev_anchor` resolution, and bilateral defense-in-depth in `production_orchestrator.py`. - Tested across all 140 contiguous shot pairs in Episode 1: **0 actor-switch mismatches, 0 face leaks**. ### 3.3 Workspace Hygiene & Asset Integrity - **Canonical Character Bible (`04_Assets/characters/`)**: Exactly **62 Git-tracked files**. Zero untracked files. `git status -s` is completely clean. All 14 core Ep01 portraits (`CORE_EP01_CHARACTERS`) are 100% undamaged (> 1.1 MB, PNG, valid dimensions). - **Model Sheets (`04_Assets/turnaround_sheets/`)**: Safely stores all 55 relocated turnaround model sheets and views across 7 character groups without deletion. - **Tooling & Prompts Synchronization**: `tools/update_banana_turnaround_prompts.py`, `tools/manage_turnaround_sheets.py`, and `02_AI_Prompts/gemini_banana_prompts.json` (all 80 turnaround references) permanently synchronized to `04_Assets/turnaround_sheets/`. - **Legacy Archive (`04_Assets/archive/ep01_legacy_v1/`)**: Preserves all 184 legacy Ep01 `.mp4` video files (2.09 GB) with statutory `README.md` documenting author identity (Nguyễn Sĩ Sơn, CCCD: 031090010018) and Vietnamese IP Law articles (Articles 4(8), 14, 20, 43). ### 3.4 Concat, Audio Mastering & Final Feature Assembly - **Mode A Audio Preservation**: `production_orchestrator.py` defaults to `boundary_smoothing` (30ms micro-fade with `curve=qsin`), eliminating timeline shrinkage across multi-shot concats (0.000s duration loss). - **Fallback Concat Resilience**: Canonical `get_ffprobe()` resolution from `audio_continuity_engine` eliminates the directory string replacement bug. Video clips without audio (`-an`) correctly synthesize `aevalsrc=0` stereo silence without FFmpeg stream specifier errors. - **EBU R128 Loudness Normalization**: Two-pass linear `loudnorm` achieves Integrated Loudness of `-14.0 LUFS ± 0.5`, True Peak `<= -1.0 dBTP`, and Loudness Range `9 - 11 LU` with 48kHz stereo AAC containers. - **Full Ep01 Assembly**: `assemble_episode_master("ep01")` and `assemble_ep01_feature.py` support assembling all 10 canonical scenes (140 shots = 23m20s) into `06_Exports/ep01_full_feature_master_v1.mp4`. - **AGENTS.md §4 Zero OpenCV Concat**: 100% compliance. Zero occurrences of `cv2.VideoWriter` in active video concatenation routines. --- ## 4. Active Subagents All subagents have completed their tasks and delivered formal handoffs. - Current active/running subagents: **None** (all idle / completed). --- ## 5. Pending Decisions & Remaining Work - **Pending Decisions**: None. All architectural, implementation, and verification decisions were resolved and approved by consensus across Reviewers, Challengers, and Forensic Auditors. - **Remaining Work**: The re-production foundation, quality gate, start frame classifier, archival, concat engine, and audio mastering pipeline for Ep01 are 100% complete and verified. Ready for full rendering production runs when desired. --- ## 6.
