+
+## User Request
+
+User asked to:
+1. Review files in `./docs` directory related to API documentation
+2. Save chat history to note.md
+
+## Files Reviewed
+
+### 1. API_REFERENCE.md
+- Base URL: `http://localhost:3002/api/v1`
+- Port 3000 is used by Gitea, API runs on 3002
+
+**Endpoints:**
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| POST | `/api/v1/register` | Register a video file |
+| GET | `/api/v1/progress/:uuid` | Get real-time processing progress via Redis |
+| POST | `/api/v1/search` | Natural language search using RAG |
+| GET | `/api/v1/lookup` | Lookup video UUID by path or get video details |
+| GET | `/api/v1/videos` | List all registered videos |
+
+**Processor Status Values:**
+- `pending` - Not started
+- `info` - Starting/info message
+- `progress` - In progress
+- `complete` - Finished
+- `error` - Failed
+
+### 2. CHUNK_DESIGN.md
+**Design Principles:**
+- Dual UUID system (external_uuid + internal id)
+- Internal tables use `videos.id` (4 bytes) instead of uuid (32 bytes) for space efficiency
+
+**Database Tables:**
+- `videos` - File mapping table with internal ID
+- `pre_chunks` - Pre-processed chunks from ASR, CUT, TIME, YOLO trace
+- `frames` - Single image recognition results (YOLO, OCR, Face per frame)
+- `chunks` - Final chunks after combination rules
+- `chunk_vectors` - Vector embeddings
+
+**Combination Rules:**
+- Rule 1 (Direct): pre_chunk → chunk
+- Rule 2 (Enrich): pre_chunk + frames → enriched chunk
+
+### 3. CHUNK_SPEC.md
+**Chunk Types:**
+| Type | Description | Can Overlap |
+|------|-------------|-------------|
+| Sentence | Speech recognition segments | Yes |
+| Cut | Scene detection segments | Yes |
+| TimeBased | Fixed duration segments (default 10s) | Yes |
+
+**Time Coordinate System:**
+- All times in seconds (float with microsecond precision)
+- Frame calculation: `frame_number = floor(time_in_seconds * fps)`
+
+**Chunk ID Format:** `{chunk_type}_{chunk_index:04}`
+- Examples: `sentence_0001`, `cut_0002`, `time_based_0015`
+
+**Processors:**
+| Processor | Model | Description |
+|-----------|-------|-------------|
+| ASR | WhisperX (faster-whisper) | Speech recognition |
+| CUT | PySceneDetect | Scene detection |
+| YOLO | YOLOv8n | Object detection |
+| OCR | EasyOCR | Text recognition |
+| Face | OpenCV Haar Cascade | Face detection |
+| Pose | YOLOv8n-Pose | Pose estimation |
+
+### 4. SERVICES.md

+| PostgreSQL | 5432 | Video metadata storage |
+| Redis | 6379 | Cache and job queue |
+| Ollama | 11434 | Local LLM inference |
