Go daemon listening on :8770 that fronts mvoice (8766), whisper-server
(8178), ollama (11434), comfyui (8188) behind a single /v1 façade.
What this MVP does:
- Loads config/consumers.yaml: routing table, per-consumer URL + health +
paths + vram_resident_mib + can_coexist_with + load/unload routes.
- Background health probe (5s) on every consumer; refuses fast with a
structured 503 if the last probe failed (no Felix-Banholzer-style
silent fallback).
- POST /v1/{tts,stt,llm,image} proxies the request body + Content-Type
to the routed consumer's path and streams the response back.
- GET /audio/* proxies to audio_proxy consumer (wa.sh fetches its WAV
this way).
- GET /v1/status exposes live GPU sample (nvidia-smi every 2s),
per-consumer health/loaded/gpu_resident_mib/active/total_requests,
scheduler stats.
- GET /healthz, GET / — broker liveness.
The Scheduler interface is in place but the implementation is
'Passthrough' — every job runs immediately, no lock, no queue. Schritt 4
replaces it with a serialising mutex; Schritt 5 adds VRAM-pressure
eviction. The interface boundary means server.go stays unchanged.
Out of scope here:
- Schritt 3: wa.sh migration (parallel work in mAi).
- Schritt 4: queue + global GPU lock.
- Schritt 5: nvidia-smi-driven LRU eviction.
Tests: config validation (good/bad), proxy forwards body, audio proxy
streams bytes, unhealthy consumer returns 503, /v1/status JSON shape.
