+Default-model initialization runs after publishing and accepting the sign-in frame, without delaying subsequent account frames. Failures are recorded with `console.error` in the renderer Console and do not mark the signed-in account as failed. Profile and balance reads also report only failures, without account data or raw exceptions; successful refreshes and account frames are silent.
 
 Read-only onboarding settings and a failed initial account stream leave the workspace accessible. A failed initial settings read exposes Retry, which reissues the shared settings read. Overlapping onboarding and Platform overlays release background interaction only after their last owner unmounts.

 The authenticated client supplies its browser-accessible callback origin, including the local SSH forwarding port, and its UI kind. The provider fixes the callback path and binds the resulting redirect_uri to both initialization and exchange. Callback requests use state and PKCE validation rather than RPC authentication. Completion, cancellation and disposal remove only the attempt route. Exchange failures publish failed state without retrying: Web closes its authorization tab and keeps the failure dialog in the original tab; the callback page attempts to close itself and offers a manual-close message. Desktop receives HTTP 204 and focuses its existing login UI through the account stream.
 
-Host diagnostics use the `[deepseek-account]` prefix on standard output and in the Host inspector Console. They include endpoint paths, HTTP status, numeric response codes, failure stages, invalid field paths, received types and validation codes, and browser URL rejection rules; headers, request and response bodies, authorization URLs, and raw exceptions are excluded.
+Host diagnostics use `console.error` with the `[deepseek-account]` prefix on standard error and in the Host inspector Console, only for request, response-validation, or sign-in failures. Successful requests, caller cancellation, and normal account state changes are silent; request timeouts remain failures. Failure diagnostics include endpoint paths, HTTP status, numeric response codes, failure stages, invalid field paths, received types and validation codes, and browser URL rejection rules; headers, request and response bodies, authorization URLs, and raw exceptions are excluded.
 
 `rewriteBrowserOrigin` defaults to `false`, requiring same-origin browser URLs. A private development patch may set it to `true` to map authorization and completion URLs to `platformOrigin`, preserving their fixed paths and query strings. Source URLs must use HTTPS or already match the configured origin; user information, fragments and unexpected paths remain rejected. Shipped profiles retain strict same-origin validation.
