 - **New RFC: Stable Assistant Turn Anchors for Live-to-Final rendering.** Defines a frontend presentation/reconciliation model for anchoring one assistant turn across live streaming, settlement, replay/reload/recovery, Compact Worklog, Transparent Stream, terminal states, artifacts, and side effects. (#3926)

 ### Fixed
 
-- **On a non-default profile, Settings → Providers no longer times out and the model picker now shows that profile's configured providers/models.** WebUI profile switching is per-client/cookie-scoped (#798), but the read-only `GET /api/providers` and `GET /api/models` endpoints resolved provider credentials from the process-global default profile instead of the active per-request one, and the `/api/models` disk cache was a single file shared across all profiles (whose profile-specific fingerprint forced a cold rebuild — and the serial provider probes behind it — on every non-default-profile open, pushing the request past the 30s frontend timeout). Both endpoints now apply the active profile's `.env` for the duration of the read (mirroring streaming), and the models disk cache is profile-keyed (`models_cache.<profile>.json`), so each profile keeps its own warm cache and resolves its own credentials. The default profile is unaffected (the env-wrap is a no-op and the cache filename is unchanged). (#3957)
