 ## Tech debt
 
-- **Android build not yet run on the 2026-10-12 fixes.** The tech-debt
-  pass changed the APK asset mount (`web/static/audio/` is now the
-  assets root, so clip paths dropped the `audio/` prefix) and was only
-  compiled against a JVM-only harness — no Android SDK on the dev host.
-  CI's `android-debug` job (lint, test, assembleDebug/Release) must pass,
-  and a debug APK must play a clip, before the next release tag.
 - **Android loading-flag timeouts.** `MasterStore.loading` and
   `PlayerUiState.loading` have no timeout; a hung DataStore read would
   leave the UI on its loading state. (Web has no async loads.)
