 ### Fixed
 
+- **The "Response complete" notification now previews the final answer, not the start of the stream.** The browser/PWA completion notification body was built from the live streaming accumulator sliced to 100 chars, so it showed the *beginning* of the response (often a preamble or empty) rather than what the user actually got. It now derives the preview from the settled final answer (anchor projection → message content → raw text), strips inline thinking, normalizes whitespace, and truncates at 100 chars — and works for completions that finish while the session isn't the active pane. Thanks @claw-io. (#5036, fixes #5035)
+
 - **Onboarding now has the same searchable model picker as Settings.** A fresh install (e.g. an OpenRouter-only first run) previously showed only a small default model list in the onboarding step — no search box and no way to enter a custom model ID — so picking a model not in the short list meant finishing setup and fixing it later. Onboarding now reuses the same searchable picker (with custom-model-ID entry) that Settings uses, instead of a separate onboarding-only dropdown that could drift. The custom-provider free-text branch is unchanged, and the plain-`<select>` fallback (when the shared picker is unavailable) correctly preserves a saved/default model instead of resetting to the first option. Thanks @rodboev. (#5031, fixes #4706)
 
 - **French localization is complete again — 40 missing UI strings now have French translations.** The `fr` locale was missing ~40 keys that exist in English (goal status messages, profile management, session metadata, upload/checkpoint messages, "Open in VS Code", and more), so those strings fell back to English for French users. All 40 are now translated, idiomatic-French wording fixes from the contributor are applied (including correcting a machine-mistranslation of "Steer" → "Bœuf"/beef), and the `theme_usage` non-breaking space before the colon is preserved per French typography. Thanks @Pichatu. (#4876)
