- Endpoint: per-API-key model allowlist (schema v3) enforced on chat (403)
and /v1/models; Full-access toggle + multi-select picker in Keys UI.
- Providers: honor x-connection-id in /v1/chat/completions — pinned requests
no longer rotate to another account on failure.
- Providers: strategy saves merge into stored enabled:false override;
Test All groups match grid sections; 1-by-1 skips disabled connections.
- Dashboard: provider-card toggle syncs from server on failure; grid toggles
always visible; connection rows get clear-✕ for stale error banners.
- Combo editor: on desktop (xl+) the Add-Model picker opens as a floating
side panel beside the untouched combo popup instead of stacking on top;
mobile keeps the full-screen overlay.
- Long API-key overflow fixed in key rows + provider model sections.
