+## Companion56 physical background failure — 2026-10-07
+
+- Operator reports audio stops about five seconds **after locking the phone or
+  switching apps**, with no playback notification. Foreground playback works.
+  This is a failed acceptance check, superseding the earlier nearly-finished
+  status; automated browser and Robolectric passes do not close it.
+- USB debugging is unavailable (operator corrected the initial can-connect
+  response). Do not keep requesting USB or claim device logs were inspected.
+- Actual delivered APK manifest includes CompanionAudioService, mediaPlayback
+  foreground type and required foreground-service permissions. This verifies
+  packaging only, not service startup on the phone. No root cause confirmed.
+- Companion retains its dashboard WebView across navigation. Operator was asked
+  to use the existing Restart app action, reconnect to Yaya, play a free demo,
+  and check for the notification before backgrounding, to rule out a retained
+  page from before the matching UI deployment. No result yet; not a fix claim.
+- No replacement APK, real payment, phone reset or wallet change performed.
+- IndeeHub agent committed final dispatch fixes as 2bfa84ef: isolated backend
+  suite 2,004 passed, zero failed, five ignored. VM-only binary preparation and
+  isolated full update/recovery rehearsal are ongoing; no live activation.
