RainbowBird fb0e149c4a feat(server): finalize in-process LLM/TTS router cutover ... End-state of the multi-step KTD-5 / KTD-6 / U8 work. The knoway sidecar is no longer reachable from server code; the router is required at boot and now owns chat completions, TTS synthesis, and voice catalog listing. Highlights: - LLM_ROUTER_MASTER_KEY becomes required; app.ts drops the graceful- skip branch and the chat fallback fetch path is gone. - /audio/speech and /audio/voices route through new routeTts / listTtsVoices entries that reuse the chat key-rotator + per-attempt timeout + abort propagation. - DEFAULT_CHAT_MODEL / DEFAULT_TTS_MODEL move from env to configKV so default-model swaps are hot-reloadable via Pub/Sub. - GATEWAY_BASE_URL removed from env schema, .env, .env.local, smoke, verification harness. Redis upstream-voices cache deleted — catalogs come from in-process adapter JSON. - routeTts splits adapter error contract by ApiError statusCode: 4xx propagates without fallback; 5xx folds into the network-failure fallback path. handleTTS wraps billing + span attribute in try/finally to plug a span leak when ttsMeter.accumulate() throws. - seed-router-config.ts rewritten with --merge (default) / --reset / --dry-run modes and env-var key handoff (OPENROUTER_KEY / AZURE_KEY / DASHSCOPE_KEY) so prod seed flows never put plaintext on the CLI. Adds DashScope CosyVoice seeding. Docs (CLAUDE.md, architecture-overview.md, transport-and-routes.md) reflect the new boundary. verifications/llm-router.md replaces the overstated "U1-U9 shipped" line with an evidence-vs-pending table. Tests: full 40-file / 343-case server suite green. New regressions pin ApiError 4xx → no-fallback, ApiError 5xx → fallback, TTS billing failure → span closed and error propagated.		2026-05-16 03:21:24 +08:00
