 | State reducer | `crates/chanora_state/src/lib.rs` | Reused the main snapshot reducer for reconnect snapshots instead of duplicating normalization and delta construction. |

 | Gap | Risk | Required evidence before release claim |
 |---|---|---|
 | Android Keystore-backed DEK remains deferred | Android identity/bookmark encryption has weaker fail-safe properties than final target secure-storage design. | Android secure-storage audit or waiver; explicit release-readiness limitation. |
-| Android runtime verification not executed in this review | Rust unit tests pass, but device permission/audio/lifecycle paths are not proven without a connected device or emulator. | `adb devices -l` showing a target plus Android build/install/smoke evidence. |
-| Android target compilation blocked locally | Android build evidence cannot be recorded while the Android NDK compiler `aarch64-linux-android-clang` is unavailable in the local toolchain. | Install/fix the Android NDK toolchain, rerun Android target build, then install/smoke on an authorized target. |
+| Android permission/audio lifecycle needs deeper route exercise | Build/install/launch smoke now passes on the emulator, but full permission-flow and audio-route lifecycle behavior still need an interactive scenario or device test before release. | Device/emulator scenario covering permission request/denial/grant, voice controls, foreground service, audio focus, and route/SCO transitions. |
 | iOS device runtime verification not executed in this review | The iOS audio-session error path is hardened, but VoiceProcessingIO/session ordering and runtime audio behavior still need device evidence. | iOS device or simulator build/run plus audio-session smoke evidence before iOS runtime success is claimed. |
 | VAD / VoiceActivity wording drift | VAD assets, tests, and scaffolding exist, but product-enabled `VoiceActivity` remains reserved/disabled per DEC-030. | Release, README, and verification wording must distinguish scaffolding/assets/tests from shipped product behavior. |
 | Protocol voice packet re-export is an intentional exception | Future maintainers may assume complete protocol isolation and accidentally widen the Seam. | Architecture note in SAD/SDD or a decision-register entry. |

 ## 6. Android ADB Status for This Review
 
-`adb` is installed at `/opt/homebrew/bin/adb`, but `adb devices -l` returned no connected devices. Android runtime verification is therefore blocked until a device or emulator is connected and authorized.
+`adb devices -l` now reports an authorized emulator target:
 
-Android target compilation is also blocked locally until the Android NDK compiler `aarch64-linux-android-clang` is available. No Android runtime success, permission-flow success, or audio-lifecycle success is claimed by this review.
