# Trixie API Shared versioned HTTP and authenticated WebSocket contracts for `trixie-server` and `trixy-linux-client`. This repository contains schemas, shared enums, error codes, compatibility fixtures, contract tests, and API documentation only. The first contract slice is under `contracts/v1/` and `fixtures/v1/`. It covers server readiness, health, errors, and the transport-neutral realtime event envelope so the client and server can be developed and tested together before Twitch integration. It also defines the first administrator authentication request and response envelopes; bearer values in fixtures are synthetic only. Twitch OAuth link and completion response envelopes are also versioned here; fixtures contain no real credentials or tokens. The shared boundary vocabulary includes the ordered permission levels in `contracts/v1/permissions.json` and the client/server compatibility result in `contracts/v1/version-negotiation.json`. Server-owned state is delivered as the authenticated `realtime-event.json` envelope; clients must ignore event types they do not understand. Guest Star channel settings are described by `contracts/v1/guest-star-channel-settings-response.json`. The browser-source token is a server-to-authenticated-client value and fixtures use a synthetic placeholder only. Destructive backup recovery uses the explicit `backup-restore-request.json` and `backup-restore-response.json` contracts; test fixtures contain no real database paths or credentials.
