Stand up Open WebUI v0.11.0 parallel to lobe-chat (:3210) as an
operator-approved candidate replacement. Env-declarative config
(ENABLE_PERSISTENT_CONFIG=False = the deploy is the config source of
truth), model picker auto-tracks the LiteLLM gateway with no pins,
background task model pinned to summarizer, TTS routed direct at the
dots gateway (:8198).
Gates verified on the box: G1 (declarative config, both directions),
G2 (picker == live gateway roster, no hand-listing), G3 (models/sync
genuinely reconciles create+delete), G5 (task model pinned). G4 (TTS)
handed to tts-dev.
Credential posture (G6): fresh capped LiteLLM key open-webui-esh
(all-proxy-models, $50/1mo budget) rather than inheriting the uncapped
lobe-chat-esh key; signup locked off after admin creation. Secrets
vaulted under esh-docker-vm/open-webui-*.
Note: the API-key toggle env var is ENABLE_API_KEYS (plural); a var
only reaches the container if compose names it in environment:.
lobe-chat is untouched.
