## Status
All implementation tasks completed. Final test suite verification in progress.

## Plan & Progress
1. [x] Setup DISPATCH.md and BRIEFING.md
2. [x] Read and analyze all required explorer handoffs and contracts:
   - `ORIGINAL_REQUEST.md`
   - `PROJECT.md`
   - `explorer_m4_1/handoff.md` (`proposed_server_production.py`, `test_proposed_server.py`)
   - `explorer_m4_2/handoff.md`
   - `explorer_m4_3/handoff.md` (`analysis.md`, `proposed_frontend_enhancements.js`)
3. [x] Native Impact Guard Protocol acknowledgment for all target files (`server.py`, `run_shot.py`, `index.html`, `PROJECT.md`).
4. [x] Upgrade `05_Production_Pipeline/run_shot.py`:
   - `--shot` alias added for `--shot-id`
   - `--prompt` made optional with auto-resolution from `muse_ai_video_prompts.json`
   - `--input-frame` made optional with auto-resolution from `resolve_start_frame`
5. [x] Upgrade `web_review/server.py`:
   - `DEFAULT_PORT = 1515`, `DEFAULT_HOST = "0.0.0.0"` exposed
   - `ConcatRequest(scene_id, output_path, crossfade_dur)` defined
   - `GenerateRequest` with root validator requiring either prompt or shot_id
   - `POST /api/concat` implemented with 409 Conflict guard and background runner
   - `POST /api/generate` modernized with `shot_id` routing to `production_orchestrator`
   - Filterable `/api/shots` and `/api/scenes` with `?episode=` and `?scene=` queries
   - `/api/matrix/ep01` endpoint serving 188 shots matrix across 15 scenes
   - `build_library_data()` indexing scene masters from both `04_Assets/videos/` and `06_Exports/`
   - Safe UTF-8/ascii console output in `log_msg()`
6. [x] Upgrade `web_review/templates/index.html`:
   - Added `🎞️ Ma Trận 188 Shots (EP01)` tab navigation
   - Added full 15-scene matrix pane with stats and filters
   - Added status badges (`✓ Đã Render`, `⏳ Chưa Render`)
   - Added 2-column Shot Detail Modal with Sweet-spot 720p Start Frame prompt, Muse.ai motion prompt, Lip-Sync Closed Lips Guard callout, and Audio Guard callout
   - Added "🎬 Ghép Master Cảnh" button in scene headers
   - Updated `pollStatus()` with `concatenating` styling
7. [x] Update `PROJECT.md`:
   - Milestone 3 Status -> `DONE`
   - Milestone 4 Status -> `IN_PROGRESS`
8. [x] Verification:
   - `python tests/run_all_tests.py`: 155/155 tests passed (100.0%)
   - `python 05_Production_Pipeline/run_shot.py --help`: `--shot` works
   - `test_proposed_server.py`: 12/12 passed
   - `pytest tests/ -q`: running task-189
9. [ ] Author hard handoff report (`handoff.md`) and notify parent agent
