kenny lopez 19b476bae5 fix(theme): refresh appearance snapshot on edit and hold mobile edits until hydration
Second pass on the community-theme sync engine, closing four data-loss defects
re-flagged in review. All are silent persistence/sync bugs; no UI or feature
behavior changes.

Desktop, snapshot lifetime and refresh:
- The appearance snapshot that seeds no-record communities was captured once
  and never cleared, so after a user changed glass/opacity/prominent-tab a later
  empty community resurrected the stale pre-migration value and republished it
  over the current choice. Refresh the durable snapshot on a genuine user glass
  edit only; accent- or theme-only edits leave it untouched so a community's own
  glass can never leak into the profile-wide seed, and programmatic per-community
  applies never reach the persist branch.
- The snapshot lived on the per-community controller instance, which remounts
  under a keyed provider, so a full store lost it across mounts and the next
  community re-captured the previous one's already-rewritten appearance. Back
  the capture with a module-level in-memory cache so the profile's first-seen
  value survives a full store for the life of the process.

Mobile, merge and hydration gate:
- Merging desktop-only glass from a decoded full cache trusted stale fields, so
  a mobile accent edit republished stale glass over current relay state. Always
  overlay the observed remote's desktop-only fields; mobile has no glass-editing
  UI, so those fields are never locally authored, only inherited.
- The pre-hydration hold could strand an edit forever when the first fetch
  returned unavailable and the subscription stayed quiet. Add a bounded-backoff
  hydration recovery that re-queries and releases the gate, mirroring the
  subscription-retry pattern, with cleanup wired into cancelPending and dispose.

Buzz Mobile

Flutter mobile client for Buzz.

Setup

cd mobile
flutter pub get

Run

# From repo root (recommended — starts Docker, relay, and simulator):
just mobile-dev

# Direct (requires services and relay already running):
cd mobile && flutter run

Worktree-aware debug identity

Debug builds produced from a git worktree get a unique app identifier keyed to the worktree directory name (com.buzz.buzzMobile.<slug> on iOS, xyz.block.buzz.mobile.<slug> on Android) plus a display-only branch label in the app name (Buzz (my-branch), or a short SHA when the worktree is detached). Because the identifier follows the directory rather than the branch, one worktree keeps exactly one installed app — and its login state — across branch switches, and builds from multiple worktrees install side by side, mirroring the desktop dev experience. Release and profile builds always keep the production identity and name.

just mobile-dev and just mobile-build-android apply this automatically by running scripts/mobile-worktree-overrides.sh, which writes two gitignored files:

  • mobile/ios/Flutter/WorktreeOverrides.xcconfig (included by Debug builds only; a developer's AppOverrides.xcconfig is included after it, so app-specific overrides like a personal BUNDLE_IDENTIFIER for device signing always win)
  • mobile/android/worktree.properties (read by the debug build type only)

For direct Xcode / Android Studio / flutter run development, run ./scripts/mobile-worktree-overrides.sh from the repo root once per branch switch to refresh the display label (the install identity never changes); the persisted files are then picked up by any subsequent build. In the main checkout the script is a no-op that removes stale override files, restoring the plain Buzz identity.

To remove leftover worktree-suffixed installs from booted iOS simulators and connected Android emulators, run just mobile-clean (add --dry-run via ./scripts/mobile-worktree-clean.sh --dry-run to preview). Production installs are never touched.

Checks

dart format --output=none --set-exit-if-changed .
flutter analyze
flutter test

Or from the repo root: just mobile-check and just mobile-test.

Android release signing

Android release builds fail unless all upload-key inputs are supplied through the environment:

  • BUZZ_ANDROID_UPLOAD_KEYSTORE_PATH: path to a CI-vended keystore file
  • BUZZ_ANDROID_UPLOAD_KEYSTORE_PASSWORD
  • BUZZ_ANDROID_UPLOAD_KEY_ALIAS
  • BUZZ_ANDROID_UPLOAD_KEY_PASSWORD

The keystore path must be absolute, and the keystore must remain outside the repository. Development and debug builds do not require these variables.

Release pipelines that sign through the central APK Signer service instead of a local upload keystore must set BUZZ_ANDROID_RELEASE_SIGNING=external. That mode produces an unsigned release bundle and refuses to run if any BUZZ_ANDROID_UPLOAD_* value is also set.
