## Summary
- downgrade Mobile Huddle authentication and native media configuration
from protocol v3 to the currently deployed relay's v2 contract
- restore the released one-byte relay peer prefix while retaining later
reconnect, roster, and playout-reset reliability fixes
- update Android, iOS, protocol documentation, and focused tests
together
Protocol v2 does not carry v3's occupancy epoch on audio frames, so it
cannot fence the narrow delayed-packet/peer-index-reuse race. This is an
intentional compatibility tradeoff until the relay v3 rollout is ready.
### Related issue

- Android debug build installed and launched on Pixel 10 as
`xyz.block.buzz.mobile.sprout_mobile_profile_settings`; foreground
process verified

A live two-device Huddle audio call remains a manual verification step.

**Category:** new-feature
**User Impact:** Mobile users must confirm with Face ID, biometrics, or
their device passcode before sending their Buzz identity to Desktop.
**Problem:** A signed-in phone could send its full identity, including
the `nsec`, to a desktop without fresh local verification.
**Solution:** Require OS device authentication before opening the
identity-recovery scanner, retain that authorization only for the active
pairing session and short pairing window, and require fresh
authentication again if it expires before the identity payload is sent.
Normal app opening, identity import, and community removal remain
unchanged.

**Android and iOS integration**
- `mobile/android/app/build.gradle.kts` declares the AppCompat
dependency required by the biometric activity theme.
-
`mobile/android/app/src/main/kotlin/xyz/block/buzz/mobile/MainActivity.kt`
uses the activity type required by the system authentication prompt.
- `mobile/android/app/src/main/res/values/styles.xml` and
`mobile/android/app/src/main/res/values-night/styles.xml` use the
compatible launch theme.
- `mobile/ios/Podfile.lock` records the native local-authentication
dependency.
- `mobile/ios/Runner/Info.plist` explains why Buzz requests Face ID
access.
**Identity policy and pairing flow**
- `mobile/lib/shared/security/sensitive_action_authorizer.dart` wraps OS
authentication and maps platform errors to stable app-level outcomes.
- `mobile/lib/shared/community/community.dart` and
`mobile/lib/shared/community/community_storage.dart` persist the
sensitive-action policy.
- `mobile/lib/features/invites/invite_join_provider.dart` assigns the
explicit policy for invite-created communities.
- `mobile/lib/features/pairing/pairing_provider.dart` gates export,
binds grants to the active community/session, reauthenticates expired
grants, and clears grants on every terminal path.
- `mobile/lib/features/pairing/pairing_page.dart` lets users choose
biometric protection while importing an identity.
- `mobile/lib/features/settings/settings_page.dart` wires pairing into
settings.
- `mobile/lib/features/settings/settings_page/connection_section.dart`
authenticates before opening export recovery and bounds the
foreground-resume wait.
- `mobile/pubspec.yaml` and `mobile/pubspec.lock` add and lock
`local_auth`.
**Coverage**
- `mobile/test/shared/security/sensitive_action_authorizer_test.dart`
covers native result mapping, unsupported devices, and single-flight
behavior.
- `mobile/test/shared/community/community_test.dart` and
`mobile/test/shared/community/community_storage_test.dart` cover policy
defaults and persistence.
- `mobile/test/features/invites/invite_join_provider_test.dart` covers
the invite policy.
- `mobile/test/features/pairing/pairing_page_test.dart` covers import
protection controls.
- `mobile/test/features/pairing/pairing_provider_test.dart` covers
export/import authorization, stale/reset/concurrent guards, malformed
payload cleanup, and no-export failure paths.
- `mobile/test/features/settings/connection_section_test.dart` covers
the tap gate, lifecycle resume, and timeout behavior.

## Reproduction steps
1. Pair an identity into the mobile app.
2. Open Settings and choose “Send identity to desktop.”
3. Verify Face ID, biometrics, or the device passcode is required before
the recovery scanner opens.
4. Cancel device authentication and verify the scanner does not open and
no identity transfer begins.
5. Authenticate, scan a Desktop recovery code, confirm the SAS, and
verify the identity transfer completes.
## Validation

**Category:** improvement
**User Impact:** Developers can identify which worktree produced a
mobile debug app, keep a bounded set of worktree builds installed side
by side, and preserve each worktree app's login and local state while
switching branches.
**Problem:** Mobile debug builds from every checkout currently appear as
the same “Buzz” app and share one application identity, so the running
source is ambiguous and one worktree build replaces another. A
branch-keyed identity would avoid replacement but create stale installs
and fresh app state on every branch switch.
**Solution:** Give each linked worktree a stable Debug-only application
identity derived from its sanitized directory name. Show the sanitized
branch name (or short commit SHA when detached) in the display label,
persist generated native overrides for direct IDE builds, and leave
Release/Profile identities unchanged. Worktree defaults remain lower
precedence than a developer's iOS `AppOverrides.xcconfig`. `just
mobile-clean` provides a safe cleanup path for suffixed worktree
installs while preserving production Buzz.

</details>
## Reproduction steps
1. From a linked worktree, activate the repository toolchain and run
`just mobile-dev`.
2. Inspect the running app: its label should be `Buzz
(<sanitized-branch>)`, while its application ID suffix is derived from
the worktree directory.
3. Switch branches in the same worktree, rerun the override script, and
confirm the application ID remains stable while the display label
updates. In detached HEAD, confirm the label uses a short SHA.
4. Build Debug from a second worktree and confirm both apps remain
installed side by side with independent state.
5. Build from Xcode after setting `AppOverrides.xcconfig` and confirm
developer overrides still win over generated worktree defaults.
6. Run `just mobile-clean --dry-run`, then `just mobile-clean`, and
confirm suffixed worktree installs are targeted while the production app
is preserved.
7. Build Release/Profile and confirm the production name and application
identity remain unchanged.
8. Run `scripts/test-mobile-worktree-overrides.sh`, `just mobile-check`,
`just mobile-test`, and `just mobile-build-android`.
