The sin:4098 sidecar service has been dead since the last reboot, and the
real binding mechanism is the chat-persona.ts opencode plugin (now in
madcat-plugin) that reads the operator cart file directly. The sidecar
HTTP round-trip was vestigial.
Changes:
- Remove SIDECAR_URL env, _sidecar_get_binding(), _sidecar_bind(),
_session_id_for_user() — all dead code paths.
- Add _slug_from_cart(cart): derives canonical PERSONAS slug from a cart's
persona_name (case-insensitive) or voice prefix fallback.
- Simplify _pick_system_prompt(cart): cart.system_prompt (calibrated) →
BT default. No more sidecar override layer.
- / route: bound_slug from _slug_from_cart(cart) instead of sidecar lookup.
- /api/persona POST: mutates the cart file in-place (preserves calibrated
UI prefs), creates a minimal cart for fresh operators. The opencode plugin
re-reads the cart on every turn, so switches take effect on the very next
message — no session reconnect.
- /api/persona/current GET: reads from cart, returns {slug, display, voice,
bound}.
- WS handler: re-loads cart at the start of each turn for live persona
switching; voice falls back cart.voice → TTS_VOICE.
Operator cart at /home/madcat/.local/share/chat-saiden/operators/<email>.json
is now the single source of truth.
chat.saiden.dev
A quiet channel. Spike Jonze's Her (2013) as a chat UI.

Deployment
Not deployed yet. Stages remaining:
- Caddyfile on marauder.saiden.dev (reverse proxy chat.saiden.dev → :8765)
- systemd unit for the FastAPI app
- DNS swap:
chat.saiden.devCNAME →marauder.saiden.dev(currently broken — points to deleted CF tunnel from Phase 1) - Google OAuth client production redirect URI:
https://chat.saiden.dev/auth/callback - 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.
Description
Web chat interface with persona calibration, SSE streaming, and real-time TTS playback.
