 ## Project Overview
 
-`tensors` is a Python CLI tool (`tsr`) for reading safetensor file metadata and interacting with the CivitAI API (search, fetch, download models). Built with Typer, Rich, and httpx.
+`tensors` is a Python CLI + FastAPI server for:
+- Reading safetensor file metadata
+- Searching CivitAI and HuggingFace models
+- Managing a local model database (SQLModel ORM)
+- Image gallery management
+- Model downloads with resume support
+
+Built with: Typer, Rich, FastAPI, httpx, SQLModel.
+
+## Deployment
+
+### Production (junkpile server)
+
+| Service | Port | URL | Status |
+|---------|------|-----|--------|
+| tensors API | 51200 | https://tensors-api.saiden.dev | `systemctl status tensors` |
+| ComfyUI | 8188 | internal only | `systemctl status comfyui` |
+
+**Note:** ComfyUI runs separately - no integration with tensors yet.
+
+```bash
+# Deploy to junkpile
+/deploy  # or: ssh junkpile "cd /opt/tensors && git pull && pip install -e '.[server]' && systemctl restart tensors"
+
+# Check status
+curl https://tensors-api.saiden.dev/status
+ssh junkpile "systemctl status tensors"
+ssh junkpile "journalctl -u tensors -f"  # logs
+```
+
+### TypeScript Client
+
+Package: `@saiden/tensors` (GitHub: saiden-dev/tensors-typescript)
+
+```bash
+# Regenerate client after API changes
+ruby ~/.claude/scripts/commands/tensors/generate_client.rb
+```

 ## Architecture
 
-Five modules with clean separation:
+### CLI (`tsr`)
 
-- **`cli.py`** — Typer CLI with commands: `info`, `search`, `get`, `dl`, `config`. Legacy mode auto-converts bare `tsr file.safetensors` to `tsr info`.
-- **`api.py`** — CivitAI REST API wrapper using httpx. Search, fetch model/version/by-hash, download with resume support and Rich progress bars.
-- **`config.py`** — XDG-compliant paths (`~/.config/tensors/config.toml`, `~/.local/share/tensors/`). Enums with `to_api()` methods for CivitAI parameter mapping. API key resolution: env var → config file → legacy `~/.sftrc`.
-- **`safetensor.py`** — Binary safetensor header parsing (8-byte u64 LE header size → JSON metadata). SHA256 streaming hash computation.
-- **`display.py`** — Rich table formatting for all output types. All major commands support `--json` output.

+### Modules
+
+| Module | Purpose |
+|--------|---------|
+| `cli.py` | Typer CLI commands |
+| `api.py` | CivitAI REST API wrapper (httpx) |
+| `hf.py` | HuggingFace Hub integration |
+| `config.py` | XDG paths, enums, API key resolution |
+| `safetensor.py` | Binary header parsing, SHA256 |
+| `display.py` | Rich table formatting |
+| `models.py` | SQLModel ORM (17 tables) |
+| `db.py` | Database operations |
+
+### Server (`/api/*`)
+
+| Endpoint | Description |
+|----------|-------------|
+| `/api/search` | Unified CivitAI + HuggingFace search |
+| `/api/civitai/model/{id}` | CivitAI model info |
+| `/api/db/*` | Local database CRUD |
+| `/api/images/*` | Gallery management |
+| `/api/download/*` | Model downloads |
+
+Auth: `X-API-Key` header (configured via `TENSORS_API_KEY` env var)
+
+### Database
+
+SQLite with SQLModel ORM. Tables:
+- Local files: `local_files`, `safetensor_metadata`
+- CivitAI cache: `models`, `model_versions`, `creators`, `tags`, `version_files`, `file_hashes`, `trained_words`, `version_images`, `image_generation_params`, `image_resources`
+- HuggingFace cache: `hf_models`, `hf_model_tags`, `hf_safetensor_files`
 
 ## Code Standards
 
 - Python 3.12+, strict mypy, line length 130
 - Ruff with extended rule set (E, W, F, I, B, C4, UP, ARG, SIM, TCH, PTH, PL, RUF)
 - PLR0913 (too many arguments) is intentionally ignored for CLI commands
-- Tests use respx for HTTP mocking and a `temp_safetensor` fixture from conftest.py
+- Tests use respx for HTTP mocking and pytest fixtures from conftest.py
+
+## Testing
+
+```bash
+# Full test suite
+just test
+
+# Specific test file
+uv run pytest tests/test_db.py -v
+
+# Test with coverage
+uv run pytest --cov=tensors --cov-report=term-missing
+
+# Test API endpoints locally
+uv run tsr serve --port 8000 &

+## TODO: ComfyUI Integration
+
+ComfyUI is running on junkpile (port 8188) but NOT integrated with tensors.
+
+Needed:
+- [ ] Add `/api/generate` endpoint that proxies to ComfyUI
+- [ ] Workflow template management
+- [ ] Queue job → poll for completion → return image
+- [ ] Config: `[comfyui] url = "http://127.0.0.1:8188"`
