# chat.saiden.dev

A quiet channel. Spike Jonze's *Her* (2013) as a chat UI.

```
chat.saiden.dev
  → Caddy reverse-proxy (TLS via Let's Encrypt)
  → FastAPI on marauder.saiden.dev:8765
      ├─ Google OAuth (authlib) + email whitelist
      └─ WebSocket → Anthropic API streaming
```

## Status

Phase 3 — Her-aesthetic. UI plan in `UI-PLAN.md`. Phase 1 (ttyd + CF Tunnel)
archived in `_archive-ttyd/`.

## Local dev

```bash
cd ~/Projects/chat-saiden
uv sync
cp .env.example .env
# fill in ANTHROPIC_API_KEY, GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, COOKIE_SECURE=false
uv run python -m app.main
# → http://127.0.0.1:8765
```

Google OAuth redirect URI for local dev (add to your Google Cloud Console
OAuth client): `http://127.0.0.1:8765/auth/callback`

## Deployment

Not deployed yet. Stages remaining:

1. Caddyfile on marauder.saiden.dev (reverse proxy chat.saiden.dev → :8765)
2. systemd unit for the FastAPI app
3. DNS swap: `chat.saiden.dev` CNAME → `marauder.saiden.dev` (currently broken — points
   to deleted CF tunnel from Phase 1)
4. Google OAuth client production redirect URI: `https://chat.saiden.dev/auth/callback`
5. Smoke test live

## Persona

System prompt currently hardcoded as BT-7274 (placeholder). Will swap to a
dedicated **Samantha cart** when authored — see EEMS subject `project.samantha-cart`.
