   - [x] C11 preview caching: Discord-hosted image/GIF previews (WebP 320px, hash-addressed, 5 MiB
     cap, one attempt) run after every walk in both modes. Live run `...-20260916090722`:
     `previewed: 2`; thumbs served over `/api/media/<scrape>/<item>/thumb` (200).
+  - [x] C72 Voice processing settings and the speak bypass. The TTS panel gained a **voice
+    processing** block (echo cancellation, auto gain, noise cancellation, and **off while
+    speaking**), stored in `preferences.voice` and applied live on save. While a TTS burst plays,
+    the daemon turns every supported gate off and restores the resting state when the queue drains;
+    `voice.join` applies the resting state after connecting. `voice.processing` gained a
+    `readOnly` probe (MCP `set_voice_processing` too). Verified live: gates ON at rest → all off
+    during speech → restored after. Krisp noise suppression is not a checkbox because its getter
+    ignores the setter in this client build.
   - [x] C71 Voice processing gates off. The TTS line was ramping in because Discord's automatic
     gain control (and echo/noise cancellation) were on. New `voice.processing` core action reads and
     sets the gates (defaults off) plus an optional input volume; MCP `set_voice_processing` exposes
