Operator decision 2026-06-13 (relayed by comfy-dev, confirmed in-session):
turn off the prod arbo engine's bearer auth and rely on the WireGuard
perimeter. Reverses ADR-0001's open-auth-hole-closed posture (comfy-dev owns
the ADR update on the vh/arbo side).
The app's protected-gate no-ops only when ENGINE_TOKEN is ABSENT — an empty
string still gates (verified: ENGINE_TOKEN="" -> /workflows 401). So both
inject paths are removed: the compose environment line is commented out and
the .env line deleted on the host. Result: tokenless GET /workflows 200 (was
401), matching the dev engine. Original token preserved in the host's
.env.pre-auth-off.bak for re-enable.
playbooks/arbo-disable-engine-token.yaml captures the reversible procedure.
The arbo-prompt-enhance vkey was extended to reach qwen3.5-9b-fp8 for the
hero auto-judge step (v0.11.3+), not granite-only. Confirmed via /v1/models
for the key. Docs-only; no version bump.
New stack mirroring the canonical convention for the Arbo (catalog) engine,
co-located beside comfyui on irv-ml1 per ADR-0001 D1/D3:
- engine<->ComfyUI over traefik-net container DNS (http://comfyui:8188),
SSH dependency eliminated; file ops bind the shared basedir input/output
- named local-disk volumes for the gallery SQLite (arbo_db, restic-backed)
and hero images (arbo_heroes); catalog as a ro git-checkout mount (D2)
- ENGINE_TOKEN + GRANITE_KEY via on-host .env; GRANITE via the LiteLLM gateway
- Q5 catalog-pull: manual day-1, ytvc-style webhook follow-on
Image build, /healthz, catalog in-container path, and non-root UID are
comfy-dev's to confirm (CONFIRM items in README).
