 ### Changed
+- **Audiobook-cast namespace migration.** Cast serialization, page stamping, and speaker normalization now use a private
+  scope with compatibility exports and the existing `window.TTVC.audiobook.cast` API.
+- **SillyTavern namespace migration.** Character-card parsing, import, and export helpers now use a private scope with
+  compatibility exports and a `window.TTVC.sillyTavern` API.
 - **Seed-finder namespace migration.** Seed sample generation, caching, and batch controls now use a private scope with
   compatibility exports and a `window.TTVC.seedFinder` API.
 - **Character-column namespace migration.** Character-table metadata, persisted column visibility, and completeness
