## Architecture Patterns

### Config access

```python
from config import settings
url = settings.ollama_url   # never use os.environ.get() directly in app code
```

### Singletons

```python
from dashboard.store import message_log
from infrastructure.notifications.push import notifier
from infrastructure.ws_manager.handler import ws_manager
```

### HTMX response pattern

```python
return templates.TemplateResponse(
    "partials/chat_message.html",
    {"request": request, "role": "user", "content": message}
)
```

### Graceful degradation

Optional services (Ollama, Redis, AirLLM) degrade gracefully — log the error,
return a fallback, never crash.

### Route registration

New routes: `src/dashboard/routes/<name>.py` → register in `src/dashboard/app.py`.

---

## Development Environments (tox)

**tox is the single source of truth for all Python environments.**
Never run `poetry run` directly — always go through tox. All environment
config (deps, markers, flags) lives in `tox.ini`. The Makefile and CI
both delegate to tox.

### Quick reference

```bash
tox -e unit             # Fast unit tests (default pre-commit gate)
tox -e ci               # Full CI suite with coverage + JUnit XML
tox -e lint             # black --check + isort --check + bandit
tox -e format           # Auto-format (black + isort)
tox -e dev              # Start dashboard with auto-reload
```

### All tox environments

| Environment | Purpose |
|---|---|
| `lint` | Check formatting + imports + security |
| `format` | Auto-format code |
| `typecheck` | mypy static analysis |
| `unit` | Fast unit tests, parallel |
| `integration` | Integration tests, parallel |
| `functional` | Functional tests, sequential |
| `e2e` | End-to-end tests |
| `fast` | unit + integration combined |
| `ollama` | Live LLM tests (requires Ollama) |
| `ci` | Coverage + JUnit XML (mirrors GitHub Actions) |
| `coverage` | Coverage terminal + XML |
| `coverage-html` | Coverage HTML report |
| `pre-push` | Lint + full CI suite (mirrors GitHub Actions exactly) |
| `dev` | uvicorn with auto-reload |
| `all` | All tests, parallel |

### Testing notes

- **Stubs in conftest:** `agno`, `airllm`, `pyttsx3`, `telegram`, `discord`
  stubbed via `sys.modules.setdefault()` — tests run without those packages
- **Test mode:** `TIMMY_TEST_MODE=1` set automatically in conftest
- **FastAPI testing:** Use the `client` fixture
- **Async:** `asyncio_mode = "auto"` — async tests detected automatically
- **Coverage threshold:** 73% (`fail_under` in `pyproject.toml`)

## Key Conventions

1. **Tests must stay green.** Run `tox -e unit` before committing. Run `tox -e pre-push` before pushing (mirrors CI exactly).
2. **No cloud AI dependencies.** All inference on localhost.
3. **Keep the root directory clean.** No new top-level files without purpose.
4. **Follow existing patterns** — singletons, graceful degradation, pydantic config.
5. **Security defaults:** Never hard-code secrets.
6. **XSS prevention:** Never use `innerHTML` with untrusted content.
7. **Keep routes thin** — business logic lives in the module, not the route.
8. **Prefer editing existing files** over creating new ones.
9. **Use `from config import settings`** for all env-var access.
10. **Use tox for everything.** Never run `poetry run` directly — use `tox -e <env>`.
11. **No inline CSS in templates.** All styles go in `static/style.css` (base theme) or `static/css/mission-control.css` (page-specific). `{% block extra_styles %}` must stay empty. If you need new styles, append them to the appropriate CSS file.
12. **Use the panel macro** for repeated `.card.mc-panel` markup: `{% from "macros.html" import panel %}` / `{% call panel("TITLE") %}...{% endcall %}`. See `macros.html` for kwargs (id, hx_get, etc.).
13. **Toast for transient messages.** Use `McToast.show(msg, level)` (info/warn/error) instead of rendering errors inline in the chat log. The toast container lives in `base.html`.
14. **Never block the event loop.** Wrap synchronous I/O (HTTP calls, file reads) in `asyncio.to_thread()`. Cache health-check results with a TTL when polling external services.

## Error Handling Patterns

All optional services (Ollama, Redis, AirLLM, voice, etc.) must degrade gracefully. Three approved patterns:

### Pattern 1: Optional Return (data retrieval)
```python
def get_user_setting(key: str) -> Optional[str]:
    try:
        return db.query(...)
    except Exception as exc:
        logger.warning("Setting lookup failed: %s", exc)
        return None
```

### Pattern 2: Fallback Value (computations)
```python
def compute_embedding(text: str) -> list[float]:
    try:
        return model.encode(text)
    except Exception as exc:
        logger.warning("Embedding failed, using hash: %s", exc)
        return hash_based_fallback(text)
```

### Pattern 3: Feature Disable (optional services)
```python
async def transcribe_audio(audio: bytes) -> str:
    try:
        return await voice_service.transcribe(audio)
    except ServiceUnavailable:
        logger.warning("Voice service unavailable — feature disabled")
        return ""  # Silently disable feature
```

### Service Fallback Matrix

| Service | When Unavailable | Fallback Behavior |
|---------|------------------|-------------------|
| Ollama | No local LLM | Claude backend (if ANTHROPIC_API_KEY set) |
| Redis | Cache/storage down | In-memory dict (ephemeral) |
| AirLLM | Import error or no Apple Silicon | Ollama backend |
| Voice (Piper) | Service down | Browser Web Speech API |
| WebSocket | Connection failed | HTTP polling (degraded) |
| Telegram/Discord | No token configured | Bot doesn't start (logs only) |

**Rule:** Never crash the app when an optional service is down. Log at WARNING level and continue.

---

## Frontend Architecture

### Stylesheets

| File | Purpose |
|------|---------|
| `static/style.css` | Base theme: palette, layout, header, chat, Bootstrap overrides, mobile breakpoints |
| `static/css/mission-control.css` | Page-specific styles (tasks, briefing, swarm, calm, etc.), toast system, connection indicator |

**Rule:** No `<style>` blocks in Jinja2 templates. All CSS lives in the two static files above. The `{% block extra_styles %}` hook exists for emergencies only and must remain empty in committed code.

### CSS custom properties

Defined in `:root` in `style.css`. Use these — never hard-code colours:

```css
var(--green)  var(--amber)  var(--red)  var(--purple)  var(--orange)
var(--text-bright)  var(--text)  var(--text-dim)
var(--bg-deep)  var(--bg-panel)  var(--bg-card)  var(--border)
```

### Jinja2 macros

`src/dashboard/templates/macros.html` — reusable components:

```jinja2
{% from "macros.html" import panel %}
{% call panel("TITLE", hx_get="/endpoint", hx_trigger="every 10s") %}
  <p>Panel body content</p>
{% endcall %}
```

### Toast notifications (JS)

```javascript
McToast.show('Ollama reconnected', 'info');   // green border
McToast.show('Connection lost', 'warn');       // amber border
McToast.show('Request failed', 'error');       // red border
```

## Security-Sensitive Areas

- `src/timmy_serve/` — API server, payment configuration
- Any file handling secrets or authentication tokens

---

## Entry Points

| Command | Module | Purpose |
|---------|--------|---------|
| `timmy` | `src/timmy/cli.py` | Chat, think, status |
| `timmy-serve` | `src/timmy_serve/cli.py` | API server (port 8402) |

---

## Module Map (8 packages)

| Package | Purpose |
|---------|---------|
| `timmy/` | Core agent, personas, agent interface, semantic memory |
| `dashboard/` | FastAPI web UI, routes, templates |
| `infrastructure/` | WebSocket, notifications, events, LLM router |
| `integrations/` | Discord, Telegram, Siri Shortcuts, voice NLU |
| `spark/` | Event capture and advisory engine |
| `brain/` | Identity system, memory interface |
| `timmy_serve/` | API server |
| `config.py` | Pydantic settings (foundation for all modules) |

### Change Impact Guide

| If you modify... | You should test... |
|------------------|-------------------|
| `config.py` | Full suite (`tox -e ci`) — affects everything |
| `infrastructure/` | Unit + integration + functional |
| `timmy/` | Unit tests + chat/CLI tests |
| `dashboard/routes/` | Dashboard route tests (usually isolated) |
| `brain/` | Brain client/worker tests + timmy tests |
