 ### Changed
 - **Audiobook cast normalization extraction.** Same-speaker post-cast merging now lives in
-  `audiobook-cast.js`, including dialogue-only merging, keeping deterministic segment cleanup separate from live casting orchestration.
+  `audiobook-cast.js`, including dialogue-only merging, split-sentence repair, and nearby-duplicate removal,
+  keeping deterministic segment cleanup separate from live casting orchestration.
 - **Audiobook segmentation extraction.** Quote segmentation, conservative turn-taking, and dialogue-piece validation
   now live in `audiobook-segmentation.js`; the live casting pipeline remains compatible with the same global helpers.
 - **Rehearser voice-design extraction.** Character development, backend selection, and backend-refresh synchronization
