- server/whisper-server: compose stack built from the pinned whisper.cpp
v1.9.3 release, same as the Android JNI layer
- Vulkan GPU backend (AMD Radeon AI PRO R9700 / RADV) with transparent
CPU fallback and NO_GPU override; GGML models auto-download on first
start (MODEL env, default large-v3)
- API bound to the Tailscale interface only (100.103.83.12:8080) since
whisper-server has no authentication; render-group GID passthrough for
/dev/dri
- validated locally: image builds, entrypoint downloads tiny, POST
/inference returns verbose_json with language + segments; GPU-less
fallback confirmed
