 ⚠️ Capture MUST be linear16/16 kHz/mono, so it uses an **AudioWorklet**, not MediaRecorder (which cannot emit raw PCM); `voice-pcm-worklet.js` is fetched from JS, so it is invisible to `cacheBustAssets` and borrows voice-input.js's `?v=` token — **edit the two together**.
 
-⚠️ Transcript frames carry the WHOLE running transcript, not deltas: the Claude path replaces where the Deepgram path appends. Provider choice is `voiceSettings.provider` (`auto` prefers Claude → Deepgram → Web Speech). → `docs/claude-voice-plan.md`
+⚠️ Claude transcript frames are cumulative within the current utterance: replace interims, then append each endpoint final once. An endpoint does not stop dictation unless finalization was requested. Finalization has a 5-second client backstop; reconnect cleanup salvages accumulated/interim text and releases the microphone immediately. Provider choice is `voiceSettings.provider` (`auto` prefers Claude → Deepgram → Web Speech). → `docs/claude-voice-plan.md`

+### Thinking pauses
+
+In **App Settings → Voice → Stop after silence**, choose 3, 6, 15 or 30 seconds,
+or **Manual** to keep listening until you tap the mic again (`Ctrl+Shift+V`).
+**Provider default** uses 6 seconds for Claude and 3 seconds for Deepgram or Web
+Speech. Final transcript events no longer stop Deepgram or Web Speech immediately:
+they wait for the configured silence deadline. The timeout counts from the latest
+transcript update. A browser can still end its native recognition run; extended
+and Manual dictation restart it while preserving the text and silence deadline.
+A silent run that lasts its full length never ends one, so 30 seconds and Manual
+survive long pauses. Connection failures, microphone errors, or a recognizer that
+keeps ending within a second of starting without hearing anything can still end
+a recording.
+
+On Chrome for Android, live words replace earlier partial results without repeating
+them in the input. The browser microphone bars indicate speech activity; streaming
+providers show audio levels. After Stop, dictation briefly waits for the final
+words before inserting text. Reconnecting preserves the available words and resets
+the mic so another recording can start.

 ### Dictating through your Claude login
