The 2026-09-06 headscale cutover retired irv-ml1's wg0 tunnel IP 10.100.79.3 (now 10.6.110.50). Repointed all LIVE canonical refs to the DNS NAME so the next move can't re-break them: homepage.href/siteMonitor labels across 25 stack composes, load-bearing env defaults (asset-engine INFERENCE_HOST, open-webui AUDIO_TTS_OPENAI_API_BASE_URL, skaldsong SKALDSONG_TTS_BASE_URL, zonos-gateway ZONOS_URL, dia), homepage services.yaml manual cards (Voice Design Studio, IRV-ML1), and servers/irv-ml1/ssh-target. Updated the stale 'WG tunnel' comment to the mesh reality. Left as-is: README curl-examples and .env.example comments (docs), and historical mentions in CLAUDE.md/persistent-memory. NOTE: applying the label repoints to the RUNNING irv-ml1 containers needs a recreate per service (labels read at creation); deployed .env values are separate from these canonical defaults.
stable-audio-open
Stability AI's Stable Audio Open 1.0 — text-to-audio latent diffusion.
Strong on SFX, foley, ambience, short loops. Not a music model — it
does not generate intelligible vocals or structured songs (use
ace-step for that).

API surface
server.py (custom FastAPI shim) exposes:
GET /health— returns 200 once the model is loaded.POST /v1/audio/sfx— returns aaudio/wavblob.
{
"prompt": "a vintage typewriter clacking in a quiet room",
"negative_prompt": "Low quality.", // optional, default "Low quality."
"duration": 10.0, // seconds, 0.5 – 47
"steps": 100, // 10 – 300, more = better quality
"seed": 42, // optional
"cfg_scale": 7.0 // 0 – 20
}
Why a custom shim: there's no upstream Docker image and no upstream
HTTP server for Stable Audio Open. Diffusers exposes
StableAudioPipeline cleanly — the shim is ~70 lines.
Deploy
scripts/elway irv-ml1 --playbook playbooks/deploy-stable-audio-open.yaml
Pre-deploy: visit https://huggingface.co/stabilityai/stable-audio-open-1.0
once and accept the Community License (HF token alone is not enough —
the gate is per-model). Then put the token in SAO_HF_TOKEN in .env
on the host.
Tunables
See .env.example — copy to .env on the host (lives at
/opt/docker/compose/stable-audio-open/.env, gitignored).
