Buzz push currently selects an application profile, such as `dogfood`,
during client registration. We want each gateway to serve one Apple app
configured by the operator instead. This removes profile selection from
the client, relay, and gateway, while allowing internal and public
gateways to use their own Apple identities.
This PR implements that model in the Buzz source and upstream deployment
chart. Discovery, enrollment, grants, and leases no longer carry an
application-profile selector. Each gateway has one configured Apple
application and APNs transport.
The protocol changes are incompatible with the old registration format,
so relays advertise `buzz-push-v1` instead of `nip-pl`. Old clients do
not discover the new push capability. Updated clients use separate
Keychain records and register again. The [push
notes](https://github.com/block/buzz/blob/push-capability-v1/docs/buzz-push.md)
describe the experimental contract.
Landing this PR is the first step. Publish the matching gateway image
and upstream chart, then land the [shared chart
update](https://github.com/squareup/cash-helm-charts/pull/5740) and
[gateway deployment
update](https://github.com/squareup/builderbot-platform-core-infrastructure/pull/1085).
Before cutover, stop old gateway instances and check legacy registration
state. Migrations refuse to proceed if old gateway installations or
active relay leases remain; they do not delete that state.
Physical-device verification remains necessary before production
activation.
### Validation
Gateway and focused Flutter push tests pass, as do the Swift package,
simulator build, and native notification/enrichment tests. A local relay
advertises `buzz-push-v1` without `nip-pl` or `app_profiles`. The
PostgreSQL suite passed 868 tests; its two migration-test failures were
corrected and pass a focused rerun together with the gateway cutover
guard. Chart rendering and release-contract checks pass.
Desktop JavaScript tests, desktop and web builds, native desktop
compilation, mobile analysis/tests, and desktop native tests pass. The
full Rust unit lane and prescribed `just test` command pass, including
workspace integration tests against task-isolated local services. The
production overlay now requires an explicitly supplied APNs topic, with
omission and rendered-value regression coverage. The corrected Swift
checksum assertion passes the complete package suite: 78 XCTest tests
and 42 Swift Testing tests. No physical-device enrollment or production
cutover is claimed.
Local merge validation: the embedded migration test and formatting pass
after reserving profile migration 0060 behind rollback migration 0059.
The local pre-push Rust lane failed ACP timing/steering tests
(`idle_resets_on_stdout_activity`,
`keepalive_resets_idle_past_deadline`, and the failed/missing-outcome
steering tests). ACP and its dependency manifests are unchanged by this
branch; all four pass in an isolated single-thread rerun. The documented
local-check exception skips only the Rust pre-push lane for publication;
required CI remains mandatory. Mobile and desktop pre-push lanes passed.
Combined migration validation: after rollback 0059 landed, the main
merge preserves profile migration 0060 and both embedded migration
assertions. The focused migration test and formatting pass. The next
local push again failed only the unchanged ACP idle/keepalive timing
tests (1053 passed, 2 failed, 3 ignored); other lanes passed.
Publication uses the same documented local Rust-lane exception; required
CI remains mandatory.
Follow-up review fix: removed the legacy profile column from the
copied-lease fixture. All four event-follow-up contract tests pass on
isolated PostgreSQL databases, covering desired and migrated schemas in
dual and app-only modes. Formatting passes. Publication retains the
prior passing local-lane evidence and uses the authorized pre-push
exception for the known unrelated ACP timing failures; required CI
remains mandatory.

## Summary
Use native iOS sheets for channel editing and Add Members, with profile
avatars, matching search, and destructive removal dialogs. Canvas
content becomes a tappable preview with Add/Remove actions.
Fix the Settings availability menu and clipped copy confirmation. Align
channel action messages with chat styling and keep agent identities
distinguishable across selection, attribution, and profile surfaces.
### Related issue
No duplicate found in the existing mobile Settings/channel issues and
PRs.
### Testing
- Flutter analysis, formatting, file-size checks, focused collision
regressions, and the full mobile test suite passed.
- Production UIKit picker simulator check passed: distinct
visible/accessibility labels, avatar updates, selected rows, and pubkey
callbacks. Wired into Mobile Swift CI.
- Original UI was built and tested on the physical iPhone with author
confirmation; profile/community data preserved.
- Review fixes await renewed author device confirmation before restoring
`buzz-review-completed` and ready-for-review status.

Channel titles could truncate while space remained between the
navigation buttons. The title was sized before inheriting its displayed
fonts, and longer names also hit a fixed 240-point cap.
Use Auto Layout and stack views for the title, subtitle, avatar, and
presence indicator. UIKit now updates the layout when fonts change
without resetting the title frame. The navigation bar constrains the
bubble between its buttons; short names remain compact and long names
use the available space before truncating.
[Before/after simulator
captures](https://github.com/block/buzz/pull/8137#issuecomment-6041101824)
### Validation
- All 97 native iOS tests passed on an iPhone 17 Pro running iOS 26.5.
Coverage includes inherited text size, increasing and decreasing text
size, 320/393/600-point widths, right-to-left avatar placement, presence
indicators, and title accessibility/taps.
- Exercised the production native header in the simulator and captured
the full channel name with its member count after the refactor. No
relay/community connection was needed.
- [CI passed for the Auto Layout
refactor](https://github.com/block/buzz/actions/runs/37644234496),
including mobile tests, Android debug, iOS simulator, native pagination
accessibility, and unsigned iOS release builds. Mobile push checks also
passed.
- The earlier broad local gate hit ACP deadline and desktop subprocess
timing failures; all failed tests passed on retry, including the
complete serialized ACP suite. Remaining checks and builds passed.
- Agent review completed. Human app-test confirmation is not applicable
under the author's standing Buzz mobile exception.
### Post-merge validation
During the mobile release baking period, exercise long channel names at
default and larger text sizes on narrow and wide screens; verify Back,
Huddle, and title taps remain accessible and do not overlap.

## Summary
Enter a desktop-only, random six-digit code on mobile to pair without a
desktop confirmation click. Verification uses the encrypted session,
limits guesses to five, and never treats the QR-derived transcript as
approval. Older clients retain desktop confirmation.
Adds digit-only error shakes and native haptics, a separate biometrics
choice, and a direct community-icon arrival animation. Fixes dropped
early offers and resets completed pairing so reopening or signing out
cannot get stuck.

### Release order
Deploy the updated pairing relay first, then desktop, then mobile. The
relay now allows eight events per connection (seven for a successful
fifth guess plus room for cancellation), with a corresponding bounded
delivery budget. Existing clients remain supported; older client
combinations keep desktop confirmation.
### Testing
- 103 mobile pairing tests, 270 core tests, 51 relay integration tests,
and the new real-relay fifth-guess flow passed.
- The real-relay regression verifies proof, decrypted identity import,
and completion after four wrong guesses. Restoring the old six-event cap
makes it fail.
- A paused-clock desktop regression confirms slow readiness cannot
extend the visible QR beyond protocol expiry. Mobile regression covers
typing before negotiation completes.
- Core/pair-relay Clippy and full native desktop Clippy/workspace tests
passed. Mobile analysis passed; broad mobile runs each hit an unrelated
failure (a gateway-script timeout and a native-menu missing-plugin
error), and both affected test files passed separately.
- Repository-wide Rust testing exhausted local disk space while
compiling unrelated packages. The final push omitted that
resource-blocked hook and avoided repeating the desktop/mobile runs
above; hosted CI remains required.

## Summary
Use native Liquid Glass for the iOS tab bar and expanding + menu,
preserving the existing Lucide icons, icon-only layout, badges,
accessibility labels, and tab interactions. The + uses black-tinted
glass with white controls; the selected tab has a subtle theme accent
(6% blended into the existing selection color). Android retains its
current styling.
### Related issue
No duplicate issue found. Related prior navigation work: #7281 (closed).
This change covers the tab bar and quick actions; it does not add
page-to-page navigation-bar morphing.
### Testing
- `just mobile-check` passed (formatting, analysis, and file-size

- `just mobile-test` passed: 2,678 tests passed, 4 skipped; the separate
unconfigured-push suite also passed all 3 tests.
- Widget coverage verifies native glass parameters, black + tint,
original icons, icon-only layout, tab selection, badges, and quick-menu
open/close behavior.
- Signed Release iOS build installed and launched on a physical iPhone;
the final glass and tint styling was reviewed on device. No final-app
screenshot was captured.
- Full `just ci` was attempted but stopped during desktop compilation as
available disk space dropped to 3.5 GiB. The complete repository-wide

## Summary
Replace the community switch sheet with a two-column picker. Selection
enlarges the avatar, waits with the voice-note loader for destination
channel content and layout to settle, then follows a curved path into
the header.
Cache raster icons at a maximum 512-pixel size and accept only
resource-free emoji SVGs. Cancel timed-out or disposed downloads without
delaying content readiness. Animate Edit badges in place, and open Add
Community on the pairing welcome page. Community removal lives only in
the switcher’s Edit mode. Keep the flow shared across Android/iOS, with
native iOS controls and removal confirmation, and clear navigation
backgrounds at rest.
### Related issue
Related to #8070 (community icon refresh/caching).
### Testing
- 122 focused Flutter regression tests and seven native iOS tests passed
after merging the latest navigation changes from `main`. Earlier feature
build installed and launched on a physical iPhone.
- Full mobile pre-push checks passed; regression coverage includes
gradient rendering, rejected/oversized icons, bounded persisted raster
decoding, SVG resource rejection and cache migration, timeout/disposal
cancellation, disconnected destination channels, degraded unread-history
settlement, and switching while icons refresh. Full `just ci` stopped

## Summary
Use UIKit navigation bars across iOS pages, with large titles that
collapse into the toolbar on scroll and a light native blur. Home uses
the active community name as its title and shows community and profile
avatars with centered emoji and stable loading, without flashing back to
icons. Channel headers retain the member count, tap-to-settings title,
and Huddle action. Their ultra-thin native material has a soft lower
edge and stays visible at the timeline bottom. The hidden title-layout
scroll view has its automatic edge effects disabled so it cannot add a
second backdrop.

## Summary
Move Invite, Appearance, and Remove community into a **Community
settings** section in the community-avatar sheet, above the existing
switcher. Keep the sheet untitled and use circle-minus for removal.
Personal Settings groups **Set status** and **Copy public key (npub)**
above an untitled card containing **Display name**, **Profile
description**, and **Edit photo**. Remove the leading icons from status,
public key, and Send identity to desktop; keep the latter in its own
untitled card. Remove the avatar status badge and top Edit action, and
rename the Theme page to **Appearance**. Opening the presence chip
triggers selection haptics; copying plays native iOS success feedback
and confirms with “Public key (npub) copied.”
### Testing
- Mobile formatting, analysis, and file-size checks passed.
- 111 affected widget tests passed; all 48 settings tests passed again
after the final labels and icon changes.
- Final release build installed and launched on a physical iPhone in the
separate Buzz Community preview, retaining its existing test account.
- Full repository `just ci` was blocked by local disk exhaustion during
Rust compilation. The full mobile suite passed (2,609 passed, four
skipped), plus three push-unconfigured tests. The presence and copy
feedback passed focused widget tests and analysis, including native iOS
success-channel coverage.

Long-pressing a message while the keyboard dismissed could leave the iOS
action menu visible but unresponsive. Rebuilds installed a new selection
handler before the previous hook's cleanup removed it. Keep that handler
for the native view's lifetime and dispatch to the latest callback. Also
let taps on decorative action icons reach the row control.
Added regression coverage for callback rebuilds, view
replacement/dismissal, and native icon/label/edge hit targets. The
callback regression fails before the fix and passes after it.
Validation: all 2,257 mobile tests (4 skipped), three unconfigured-push
tests, mobile analysis, 42 focused action/handler tests, and three
native XCTest checks passed. Physical iOS 26.5 taps verified
keyboard-open long press, Edit, Copy (including clipboard contents),
repeated opening, and outside dismissal. Desktop tests/builds, Tauri
checks/tests, and the web build passed. The full local gate encountered
unrelated Rust agent timeout failures; all 105 tests in the affected ACP

Make the push gateway origin configurable across the relay, gateway,
mobile client, and deployment chart.
This is a fresh deployment. The gateway has only run on personal
development infrastructure, and push has no existing enabled users.
Legacy migration, configured-to-unconfigured mobile transitions, and
rolling upgrades from pre-launch gateway binaries are not supported.
Populated pre-launch databases are rejected with an informative error
before migrations run; their data is untouched. Mobile builds may omit
the gateway URL, leaving push unavailable. Once push is enabled,
subsequent builds must retain that configuration.
### Validation
- All applicable CI checks pass at
`5f546cfaf403f0386f146d213adfb4392f4ec29c`, including Rust,
mobile/Swift, desktop/integration, security, image builds, and Helm
checks. An unrelated agent cancellation test passed on retry.
- PostgreSQL CI passed 384 tests, including the production-entry-point
regression for refusing populated pre-launch databases before
migrations, fresh initialization, and subsequent initialized
deployments.
- Focused local validation passed all 10 gateway PostgreSQL tests under
the CI discovery filter and all 3 unconfigured-mobile tests.
Repository-wide PostgreSQL discovery validation and the complete
pre-push hooks passed.
- Physical-device APNs/App Attest behavior and deployment to a live

### What changed?
Buzz mobile checks the app-store age signal at launch and hard-blocks
the app behind a full-screen 18+ notice when the store says the
signed-in person is under 18.
No age signal (e.g. declined permission, indeterminate value,
unsupported OS versions) results in no block.
The age value is never persisted. It is read, used to compute one
boolean, and discarded. Nothing is written to disk, and neither the age
value nor the range is logged or sent to analytics.
Platform notes:
- **New dependency `com.google.android.play:age-signals:0.0.4`.** This
is the only way to read the Play signal. Its AAR declares `minSdkVersion
23`, below the app's 24, so it forces **no minSdk bump**, and it
self-declares its own consent activity, so **no AndroidManifest change**
is needed.
- **iOS entitlement and linking.** `DeclaredAgeRange` autolinks from the
import. `Runner.entitlements` now declares
`com.apple.developer.declared-age-range`, and the call remains behind
`#available(iOS 26.0, *)`.
### Why?
App stores now expose a declared-age range, and Buzz's Terms require
users to be 18 or older. This wires the store signal to that rule with
the smallest change that is defensible.
Absent signals, declined or undeterminable results, and unsupported OS
versions allow the app through. A transient native request failure does
not become evidence that access is allowed: the app remains gated until
a retry produces a result. Only an affirmative under-18 signal produces
the permanent restriction screen.
### How is it tested?
Added tests:
-
[`age_signal_provider_test`](https://github.com/block/buzz/tree/main/mobile/test/features/age_gate)
covers the 17/18 boundary, open-ended ranges, no-signal, transient
recovery, bounded retry exhaustion, malformed payloads, and request-once
behavior
-
[`age_gate_app_test`](https://github.com/block/buzz/tree/main/mobile/test/features/age_gate)
proves authenticated content remains unmounted while the signal is
pending or retryable, and verifies the retry path
-
[`age_restriction_page_test`](https://github.com/block/buzz/tree/main/mobile/test/features/age_gate)
asserts the block screen offers no bypass affordance
-
[`community_provider_test`](https://github.com/block/buzz/tree/main/mobile/test/shared/community)
verifies age restriction clears push state, persists inactive leases,
and retries a failed tombstone
-
[`AgeSignalPayloadTest`](https://github.com/block/buzz/tree/main/mobile/android/app/src/test/kotlin/xyz/block/buzz/mobile)
pins the Android success payload to exactly `{status, ageUpper}` and
verifies failures return the distinct retryable platform error
### Deployment note
Enable the Declared Age Range capability and regenerate signing profiles
carrying the entitlement. This relops/App Store Connect task is not
performed by this PR.

```
relay → push gateway → APNs -> NSE -> Notification Center
## Known limitations
The APNs wake payload is intentionally constant and opaque: it contains
no originating community or message identifier, in keeping with the
implemented NIP-PL privacy design.
The Notification Service Extension must therefore reconnect to the relay
and resolve eligible messages after each wake. Around overlapping wakes,
timing boundaries, or resolution windows, notification presentation may
occasionally omit an expected message or display a message more than
once.
This best-effort behavior is deliberately accepted for the current
implementation and will be measured during the internal rollout to
determine whether the user experience is acceptable before any broader
deployment; the implementation does not claim exactly-once presentation.
## Validation
Live end-to-end hardware validation used an internal remotely hosted
development relay and push gateway, the APNs sandbox, and a physical
iPhone 12 mini:
- A second real Buzz client published a uniquely marked message through
the hosted relay.
- The relay matched the message and sent the constant opaque wake
through the hosted gateway. The gateway made an actual APNs request; no
`simctl push` or simulated notification was used.
- The iPhone received the notification on its lock screen. The
Notification Service Extension reconnected to the relay, fetched the
event, verified its ID and signature, and replaced the placeholder
content with the real notification title and body.
- After the app populated its shared presentation cache, a final marked
notification visibly showed the sender display name, sender avatar, and
hashtag-prefixed channel name.
- Tapping a lock-screen notification opened Buzz and exercised the
notification-response path and navigated to the corresponding message.
Final validation with a dogfood-signed artifact and production App
Attest/APNs configuration remains a release step.

## 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.

**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.

**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>
<summary>File changes</summary>

brace-aware Release/Profile purity, cleanup safety, ignores, and command
integration.
</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`.
