## Summary
The version line at the bottom of mobile Settings (for example `v0.27.0
(36)`) couldn't be copied, which made it awkward to paste into bug
reports. Tapping it now copies the whole string and shows a "Version
copied" toast, matching the existing "Copy public key" row. It's
keyboard-focusable and has a 48dp tap target. Partial selection isn't
supported; it's whole-string only.

### Related issue
N/A
### Validation
- Added test: tapping the footer, or reaching it with Tab and pressing
Enter, puts `v0.16.0 (432)` on the clipboard and shows the toast. The
test also checks that the tap target is at least 48dp tall.
- `just mobile-check` and `just mobile-test` pass.
- Automated simulator run (debug build, iOS 27): opened Settings, tapped
the version, confirmed via `simctl pbpaste` that the clipboard held the
exact footer text and the toast appeared; then confirmed the neighboring
"Copy public key" row still copies the npub and Settings still closes.
Human testing waived per the mobile testing exception. A full recording
was posted in Buzz instead of here because it shows internal channel
names.

## Summary
Deletes mobile code that no longer has a user-reachable path and has no
counterpart in buzz-app, so it is unlikely to come back for parity. Net:
104 files, about 5,500 lines removed. No intended behavior change.
- **iOS native message menu and action surface:**
`NativeMessageMenu.swift` and `NativeMessageActionSurface.swift`, the
`message`/`supportsMessage` coordinator branches, and the Dart selection
hook. Dart stopped creating this view in
[#8280](https://github.com/block/buzz/pull/8280). The native reactions
sheet in the same coordinator is kept.
- **Old home quick-actions launcher and `ComposeMorphIcon`:** only
instantiated in tests since the nav-bar creation actions replaced them.
- **Retired local theme stack:** `ThemeNotifier`, `AccentNotifier`,
`SchemeNotifier`, `adaptive_theme.dart`, `AccentPickerPage`, the
appearance-mode sheet and their helpers. These predate per-community
theme sync. The legacy prefs migration in
`community_theme_preference.dart` is kept.
- **Unused widgets:** `ProfileAvatar` and `MaskedAvatarBadge`.
- **Push permission-status plumbing:** the iOS
`notificationAuthorizationStatus`/`openNotificationSettings` handlers,
plus the uncalled strict age-gate snapshot registration and its Swift
`syncAgeGatePushSnapshot` path.
- **Orphaned files** with no importer: `profile_text_edit_sheet`,
`editor_option_button`, `retained_page_transition`,
`tappable_flapping_bee`, `agent_model_info`, `community_bot_profiles`,
`sheet_divider`, `success_haptic`.
- **Uncalled helpers:** the `pickAndUpload*`/camera helpers in
`media_upload.dart`, unused `NostrFilters` builders,
`mediaGetHeadersFor*`, and about 20 other uncalled functions, providers
and styles.
- **Removed-UI leftovers:** the never-wired invite directory providers,
`AuthNotifier.signOut` and `removeActiveCommunityForSignOut` (the Sign
out row is gone), `renameCommunity`,
`HomePage.profilePageBuilder`/`SettingsPage.embedded`, and the
create-forum branches of the create-channel sheet. Forum viewing is
unchanged.
Tests that only covered deleted code are removed. Tests of surviving
code that used deleted helpers as drivers were repointed to the
surviving API.
An audit of `mobile/android` found no dead Kotlin, resources, manifest
entries or Gradle dependencies, so Android code is unchanged.
## Validation
- `flutter analyze`: no issues.
- After rebasing onto main
([93b8b8f](https://github.com/block/buzz/commit/93b8b8febc)), `just
mobile-check` is clean (format and analyze), and `just mobile-test`
passes (4,070 passed, 35 skipped, 0 failed, plus the push-unconfigured
and secp256k1 suites).
- `dart format`: clean.
- Android: `just mobile-build-android` builds the debug APK, and
`./gradlew :app:testDebugUnitTest` passes.
- iOS: `build-for-testing` succeeds and BuzzPushKit `swift test` passes
(65 tests). In RunnerTests, 97 of 98 pass.
`testNativeNavigationTitleExpandsAgainAtTop` fails, but it fails the
same way on unmodified `main` (acf56fff6f) on the same machine (Xcode
27, iPhone 17 Pro simulator), so it is not caused by this change.
- Agent review of the diff ran. Its one blocker (stale `project.pbxproj`
entries for the deleted Swift files) is fixed.
- In-app smoke run at
[66141c1](66141c10b9):
a debug build on a fresh iPhone 17 Pro simulator (iOS 27), signed in to
the internal community. The following flows all worked with no errors:
- Home: the New menu (channel, DM, workspace, chat) and the
create-channel sheet, including its channel-type options.
- A chat, with the message action sheet (reactions row, Reply, Copy
link, Remind me, Mark unread, Copy text, Edit and Delete).
- Appearance: the previews, and cycling the System and Light modes.
- Settings: the profile header, the display name editor, and Edit photo
(Image and Emoji tabs).
- The Agents directory.
- Search, including the Channels filter, plus opening a team channel
from the results.
- Tapping a reaction summary, which opens the native iOS Reactions
sheet.
- The recording isn't attached here because it shows internal channels
and messages.

Standardizes mobile navigation headers: Android uses Home’s shared
Flutter blur; iOS uses native soft edges, with graduated material
retained during large-title collapse and the iOS 26 fallback preserved.
Preserves Home’s upward title motion with a soft boundary and keeps the
avatar crop title visible.
Validation: 4,112 Flutter tests and 111 native tests passed after
merging main. Rendered partial-scroll regression verified on the iOS 27
simulator; removing either review fix fails its regression assertion.
The earlier preview was installed on a physical iPhone with the existing

Reverts [#8615](https://github.com/block/buzz/pull/8615).
Mobile push for Solo chats returns to mention-only, matching buzz-app,
which alerts on every message only in DMs. This also removes the
lease-size guards #8615 added, since they existed to fit Solo chats into
the lease.
### Validation
- Clean revert of bad9d26142 with no conflicts.
- Mobile lint and the full mobile test suite pass.

Follows #8654.
Deriving an x-only public key from a secret key with
`nostr.Keys(secret).public` costs about 5.6 ms in pure Dart on an iPhone
SE (2nd gen, Profile). The app does it in 10 places, including relay
config, the signed-event relay's `pubkey` getter, push lease checks,
status updates, and the settings identity row's `build` method. This
routes all of them through `derivePublicKeyHex` from #8654, which takes
16.5 µs on the same device.
Behavior is unchanged for valid keys: output is the same lowercase hex.
For a malformed or out-of-range key the thrown type changes from nostr's
`InvalidKeyException` to `ArgumentError`; every affected site either
catches all errors or rethrows its own `FormatException`/`StateError`,
and nothing in `lib` or `test` matches on the old type.
Sites that need a full `nostr.Keys` object (key generation,
`AccountIdentityStore`) are unchanged.
### Validation
- `derivePublicKeyHex` is checked against `nostr.Keys` for 64 random
keys in #8654's `event_signing_test.dart`.
- Full mobile analyze and test suite pass on this branch after rebasing
onto main, including the package's own tests.
- iPhone 12 mini, Profile build of this stack (with #8656 and #8657 on
top): paired to the internal Buzz community through Desktop; relay auth,
identity row, avatar, and channel/DM/inbox loading all worked under the
derived key.

## Summary
Unify mobile conversations in Messages with All / Solo / Team filters, a
collapsing header, and separate Search, New, and default-agent
shortcuts. Move workspace actions into the community menu and keep
collapsed sections intact across filters.
Align Inbox and list typography, spacing, and muted controls. Preserve
native glass layering through navigation and give every filtered list
enough clearance above the footer. The default-agent shortcut reads the
shared encrypted preference and opens an existing chat immediately. When
unset, it opens Agents; a star action selects the default through a
production signed, self-encrypted preference writer. Save failures
remain visible and retryable.
Android now uses rounded navigation controls and filters, optically
balanced search icons, and expanding New/community menus with leading
Tabler icons matching iOS. Preset avatars retain transparent WebM
animation through an Android WebView renderer, with lifecycle pausing
and poster fallback.
### Related issue
None found in searches for mobile navigation issues and open PRs.
### Testing
- Android follow-up: ARM64 debug build, Dart analysis, and emulator
checks passed for menu placement, selection, icon alignment, search, and
avatar playback/pause/resume. The avatar implementation passed 3,840
Flutter tests and native Android tests before subsequent styling
iterations. Automated tests for the later menu/icon iterations were
skipped at the author’s request; those earlier results do not cover the
final styling changes.
- Mobile formatting/analysis and full test suite (3,838 passed, 23
skipped, plus 4 push-configuration tests); regression journey covers
filtering, collapse retention, and scrolling the last Solo row above the
footer.
- iPhone 18 Pro simulator (Honeycomb): filters, menus, Inbox,
Invite/Back, Switch Community, and default-agent chat/Back exercised.
iOS release build and Pairing Preview install/launch passed during
iteration, preserving the saved profile.
- P1 follow-up: production writer-to-reader widget journey covers
selection, publish failure/retry, and the unset footer opening Agents.
Simulator Agents open/close passes; its saved community has no
selectable agents, so live selection was not verified there.
- Independent agent review completed; its Solo footer-clearance finding
is fixed. The final clearance adjustment is covered by widget tests;
physical-device acceptance of that adjustment and hosted CI remain
pending.
Final Messages layout:

## Summary
Mobile push only covered Solo chats through explicit mentions. Solo
chats are private streams rather than DMs, and the push lease subscribed
channel-wide only to DMs. Agent replies in your own Solo chats therefore
never woke the phone.
The lease now subscribes channel-wide to the viewer's own joined,
unarchived Solo chats, using the same predicate as the Solo tab,
including older unlabelled Solo chats listed in the encrypted Solo
record. Self-authored messages stay excluded through the existing lease
ignores. Muted Solo chats stay out of the lease, like muted channels, so
they push only on mention. The lease waits while the Solo record loads
so an unresolved record never drops legacy Solo chats. If that record
fails with no cached copy, DM and mention updates proceed without the
legacy chats, which the Solo tab cannot list either, and they return
when it recovers. Solo chats created by someone else still push only on
mention, matching how they appear in the channel list.
A lease is bounded by its channel count (750), by the relay's advertised
plaintext and content sizes, and by NIP-44's 65535-byte plaintext
ceiling. DMs always stay, as before. Solo chats fill the remaining room
most recent first, sized with the publisher's own lease encoding, the
exact NIP-44 payload length and the largest endpoint the relay accepts.
Sizes are computed rather than built, so a relay's advertised limits
never drive an allocation. Solo chats beyond the room push only on
mention instead of failing the lease update or publication, and
Notifications settings says how many. A relay too small even for DMs and
mentions fails push setup visibly instead of saving a lease it would
reject. Publication accepts only endpoint grants in the gateway's
JSON-safe alphabet, so the sizing assumption holds.
Thread replies outside DMs still do not push unless they mention you.
That is a separate gap.
### Related issue
None found.
### Validation
- Added test: the desired lease includes joined DMs and the viewer's own
Solo chats, and includes legacy Solo chats from the Solo record, and
excludes archived and muted Solo chats, other people's Solo chats, and
unlabelled private streams. It fails without the fix.
- Added test: the sync provider holds the desired lease while the Solo
record loads, proceeds without legacy chats if the record fails, and
adds them once it arrives. It fails if loading is treated as empty or if
a failure blocks updates.
- Added tests: over the channel count, and over each size limit (relay
plaintext, relay content, NIP-44 plaintext), the lease keeps every DM
and exactly the newest Solo chats, reports the rest as omitted, and is
accepted by `publishBuzzDevPushLease` with a grant at the relay's
endpoint limit, while a max-length grant that JSON would escape is
rejected as not a gateway grant. A relay advertising a 2^50-byte
endpoint limit is sized without allocating. Each row fails if its guard
is removed.
- Added test: a relay whose content or plaintext limit cannot fit even
the lease without Solo chats rejects that lease at publication, and the
provider fails setup instead of saving it. It fails if the guard is
removed.
- Added test: the NIP-44 payload length matches real encryption at every
padding boundary up to 65535 bytes.
- Added test: Notifications settings shows "Older Solo chats notify only
on mention" with the omitted count. It fails without the row.
- Mobile lint and the full mobile test suite pass.
- Not exercised end to end on a device. A signed dev build was installed
on a test iPhone against a personal dev relay, but the phone's dev
identity owns no assistant there, so the device could not create a Solo
chat without exporting its key. This will be validated in dogfood. The
relay matcher already handles channel-wide `#h` leases for DMs, and Solo
messages use the same kind and scoping.

Push subscription setup ran synchronously inside the root widget build,
so an invalid subscription could replace the entire app with Flutter's
error surface. Push initialization and the cold-start native
notification read could also prevent the app from rendering.
Keep push work independent of the app subtree, observe asynchronous
persistence failures, and retain the original errors and stack traces.
Setup retries use bounded backoff; Settings shows a failure and offers
manual retry without resetting navigation. Retry preserves a healthy
revocation worker, and community-removal callbacks follow a recovered
worker so lease cleanup continues after setup recovery.
Related: [#8608](https://github.com/block/buzz/pull/8608) fixes the
specific unrelated-mute input that exposed this startup coupling.
### Validation
Added Flutter journeys cover invalid subscriptions, asynchronous storage
failure, dependency initialization failure, retry exhaustion and manual
recovery, navigation preservation, accessible retry actions, and
pending/failed native startup reads with notification-target recovery.
Both original rendering regressions failed before the fix.
Community-removal coverage also verifies cleanup after a worker
initialization failure and after retrying healthy setup; that regression
failed before the worker fix.
The full mobile suite passed (3,782 tests; 19 existing skips), as did
the four unconfigured-build tests and static analysis. The corrected
head also passed the full pre-push mobile checks and tests, plus 42
focused push and community tests. Rendered widget evidence uses mocked
native platform channels; no device APNs delivery test was performed.
Rendered Flutter widget evidence with synthetic data and mocked native
platform views.
### Setup failure
The app remains usable and Settings offers a retry after push
initialization fails.

### Recovery
Retry clears the error without replacing the navigator or leaving
Settings.

## Behavior
Adds optional mobile Builderlab sign-in, identity backup/recovery,
community discovery/creation, and account-aware reconnect. **Builderlab
features are disabled by default:** when `BUZZ_AUTH_DOMAINS` is unset or
empty, account login, creation, backup/recovery, reconnect prompts, and
background account restoration are hidden/disabled. QR/code pairing,
links, and invites retain Nostr-only entry. Saved account state is
retained for later opt-in.
`--dart-define=BUZZ_AUTH_DOMAINS=communities.buzz.xyz,communities.public.builderlabstaging.xyz`
opts those DNS domains and their subdomains into required account setup.
The same policy gates pairing, deep links, durable community admission,
and reconnect. A nonempty list enables Builderlab features;
`BUZZ_BUILDERLAB_URL` alone does not. Enabled flows still require their
backend services. Existing Nostr relay authentication remains mandatory.
`BUZZ_HOSTED_RELAY_AUTH=true` enables scoped relay assertions and
reconnect prompts only for configured authentication domains. Configure
assertion issuance and each community's issuer binding before enabling
assertions; enable relay enforcement last. Account credentials stay at
Builderlab. Wrong-account recovery preserves keys; failed writes are not
replayed; authentication is bounded by request deadlines.
Hosted flows preserve keys across cancellation/restart, reconcile
interrupted creation/invitation acceptance, and support manual nsec file
import/export. Account identities are scoped to backend and
authenticated subject; reusing an existing local key for an unbound
account requires an explicit selection. Recovery reconciles the
advertised and recovered inventories before automatic selection.
Successful self-hosted admission retires its pending key, and iOS
startup removes interrupted export files. Adds authenticated relay `GET
/operator/communities/joined` for the companion Builderlab membership
endpoint.
## Validation
- Follow-up review repair at `66a12ac92`: self-hosted entry presents
readable choices and import despite incomplete enumeration, while
generation still requires a complete empty inventory; explicit selection
uses exact-key lookup. Consuming a value-equal duplicate now advances
dispatch. Reconnect requires an existing account binding or a
subject-scoped backup receipt before signing an assertion, and pins the
subject inside the serialized account request. An empty different
account is refused without sending key proof. Focused checks: configured
domains 58 passed; default 49 passed, 9 hosted-only skips. Separate
isolated mutations fail the incomplete-inventory sheet, exact-key reuse,
duplicate dispatch and reconnect journeys (including an
empty-account-only bypass); restored controls pass. Evidence uses
synthetic storage/network boundaries, not physical Android or live
backend association. All mandatory commit/push hooks passed; fresh
GitHub CI is pending.
- Bounded review repair at `d3cc0003f`: incomplete secure-storage
enumeration now blocks automatic identity generation while explicit
known-key reads retain their fallback; declined/failed onboarding links
release the queue; HTTP 429/5xx keeps Retry regardless of response
encoding. Default app-gate coverage exercises a bind link followed by
ordinary community entry. Focused checks: configured domains 47 passed;
default 38 passed, 9 hosted-only skips. Removing the three production
fixes in an isolated source/Git/build copy fails the
identity-resolution, declined/failed queue, and Retry journey
assertions; clean and restored controls pass. Storage and HTTP failures
are synthetic; physical Android and live outage behavior were not
exercised. Published after all mandatory commit/push hooks passed
(mobile analysis/tests, branch-skew and file-size gates); fresh GitHub
CI remains pending.
- Existing whole-PR source review cleared the reconnect defects at
`fb15d5b82`.
- Domain-policy increment: focused environment, entry, app-gate, pairing
and onboarding journeys pass with empty and configured domains. Existing
pairing provider/page tests pass. Changed Dart files analyze cleanly.
- Isolated source/Git/build mutation: forcing paired credentials through
hosted login fails the default-build journey; clean and restored
controls pass. CI now runs configured-domain journeys in addition to the
default-build suite.
- Integrated main through `5b433d929` at `0067c069c`, including its
pinned Flutter upgrade. Preserved the PR welcome UI with the updated
transition API and added Material surfaces around onboarding
selection/consent rows. Focused post-merge runs pass in both
configurations; all mandatory local push gates passed (mobile
analysis/tests, Rust tests, desktop-native checks, branch-skew and
file-size checks).
- Merge-review repair at `a315bce11`: focused identity/storage/admission
and widget journeys pass, including account switching with an empty or
already-bound second account, explicit reuse, and self-hosted
removal/rejoin with another key. Default-domain journeys pass too
(hosted-only cases intentionally skip there).
- Isolated source/Git/build mutation checks: bypassing account scoping,
reuse consent, pending-key retirement, or recovery inventory
reconciliation fails the relevant journey/invariant assertions; clean
and restored controls pass.
- Native `RunnerTests/IdentityFilePluginTests`: both tests pass on the
iPhone 18 Pro iOS 27 simulator with an isolated app identifier. At
`24a0dcaac`, the picker journey seeds residue in Library/Caches,
matching path_provider_foundation, and verifies plugin startup removes
it while preserving an unrelated file. The earlier tmp-only fixture did
not exercise the actual export location. This is synthetic native
cleanup/picker evidence, not a real terminated-share or live account
round trip.
- Follow-up: Caches and tmp cleanup; fallback to individually known
identity slots when Android bulk enumeration fails; explicit replacement
of a refused self-hosted key preserves its original before swapping the
retry slot. Configured-domain journeys/invariants: 34 passed; default:
31 passed, 3 hosted-only skips. Isolated enumeration/retry mutations
fail with passing controls. Bulk-read fallback preserves but cannot
enumerate arbitrary other-account slots until bulk reads recover.
- Configured-domain CI exposed a stale pairing-status assertion after
account scoping. The repaired test checks the admission mismatch,
preserved account/transfer keys, and no admitted community. The
configured-domain CI selection passes locally (56 tests); removing the
production mismatch guard fails the updated test, with clean/restored
controls passing. This is synthetic coordinator evidence, not physical
QR acceptance.
- Final review repair (`40e1e6101`): native iOS export creation uses
atomic complete file protection; normal and restart cleanup remain.
Account/policy/claim HTTP uses one 30-second total deadline with request
abort and body cancellation. Removed the unrelated NIP-FA spec edit.
- Focused account/admission/export tests: 25 pass; configured-domain
account/admission/onboarding journeys: 33 pass. Isolated deadline and
native-dispatch mutations fail, with passing clean/restored controls.
Native export/picker tests: 2 pass on iOS 27 simulator. The real
file-protection attribute assertion is physical-device-only because
simulator provides no Data Protection attribute; locked-device
protection and interrupted real sharing have not been observed.
- Opt-in UI: configured-domain CI selection passes (57 tests); default
selection passes (7 tests, 10 hosted-only skips); URL-only plus
whitespace/empty domains passes (6 tests, 9 hosted-only skips). Changed
Dart files analyze cleanly. Independent mutations that unconditionally
initialize the coordinator in the app gate, welcome entry, or link form
fail the default journey; clean/restored controls pass.
- Native welcome screens exercised on iPhone 18 Pro / iOS 27 simulator
in default and configured builds: default exposes community link / QR /
pairing code only; configured build additionally exposes Builderlab
connection and community creation. No live hosted login was exercised in
this check.
- Delivery at `e48fe73a9`: all mandatory push hooks passed (full mobile
analysis/tests, Rust tests, desktop-native checks, branch and file-size
checks). GitHub checks had not yet populated at the immediate post-push
snapshot.
## Review disposition
| Feedback | Disposition |
| --- | --- |
| Explicit self-hosted entry under unreadable inventory, duplicate
invite dispatch, reconnect cross-account binding
([entry](https://github.com/block/buzz/pull/8375#discussion_r4318421622),
[queue](https://github.com/block/buzz/pull/8375#discussion_r4318421640),
[reconnect](https://github.com/block/buzz/pull/8375#discussion_r4318455512))
| Repaired at `66a12ac92`; evidence above. Reconnect refuses unproven
ownership rather than silently establishing a binding. |
| Incomplete Android identity inventory, stranded deep-link queue,
transient HTTP retry classification
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5576864143))
| All three repaired in `d3cc0003f`; focused journeys and isolated
mutation evidence above. |
| Account cross-link, incomplete recovery inventory, committed invite
checkpoint, pending local key retirement/replacement | Repaired in the
preceding commits; journey and mutation evidence above. |
| iOS interrupted key export
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575253252))
| Native cleanup plus complete protection at creation implemented.
Physical-device lock and real interrupted sharing acceptance remains
pending. |
| Trickle responses bypass idle timeout; unrelated NIP-FA edit
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575764556))
| Total request deadline/abort implemented; spec edit removed. |
| Production domains rejected | Ordinary entry now needs no Builderlab
configuration. Opt-in account-required domains must still use supported
community mappings. |
| Lost Android Keystore recovery | Backup exclusions prevent the
reviewed stale-restore scenario; genuine key loss still has no in-app
recovery/reset and remains deferred. |
| Native secp256k1 dependency question | Obsolete against the current
base: upstream C integration landed in #8398; no package diff remains
here. |
| Operator membership endpoint contract | Documentation now states the
operator chooses the pubkey; no end-user session binding is implied.
Additional handler-level coverage is optional follow-up. |
| Optional Android partial document cleanup/activity retention; local
work after backup cancellation | Follow-up hardening, not claimed
implemented. Cancellation prevents remote backup upload. |
| Semgrep crypto inventory notices | Informational inventory, not
demonstrated defects. |
## Remaining draft gates
Native QR/browser-return acceptance remains unverified for this
revision. Optional Builderlab onboarding still needs backend
backup-status and joined-community routes, recovery
policy/configuration, and real backup/recovery/reconnect acceptance. The
empty-domain build removes these services as prerequisites for ordinary
pairing; it does not make the optional hosted flows backend-ready. Human
acceptance and current CI are still required before merge.
Review dispositions retained: production auth-domain configuration must
use supported community mappings; enabling `builderlab.xyz` does not add
support for `buzz.block.builderlab.xyz`. Recovery after genuinely losing
an Android Keystore key remains a follow-up, not a newly implemented
capability.
Human acceptance steps: build once without `BUZZ_AUTH_DOMAINS`
(including with a previously saved account) and confirm no Builderlab
controls/restoration while ordinary link and QR/code entry work. Build
with supported domains and confirm connection/creation appear; exercise
browser return and live backup/recovery/reconnect. On physical iOS,
exercise export and interrupted sharing/locked-device protection. Record
results before marking review complete.

Keep notification settings as a separate card with a single
“Notifications” toggle. Remove the section heading, bell, all subtitles
(including permission/capability and pending opt-out messages), and the
iOS settings button.
Toggle callbacks, capability visibility, persisted opt-in/out, and relay
synchronization are unchanged. The disable failure is being investigated
separately. This intentionally removes the pending warning rather than
claiming to fix synchronization. Tom explicitly requested removal of the
immediate opt-out synchronization warning and all other status text;
this is an intentional exception to the pending-feedback guidance in
VISION_MOBILE.md. [Codex’s finding is answered against that agreed
scope](https://github.com/block/buzz/pull/8199#discussion_r4225426842).
No new tests. Delete tests for the removed permission/settings UI and
remove obsolete display assertions from existing recovery tests while
preserving their opt-out synchronization coverage.
Closest related issue:
[#7826](https://github.com/block/buzz/issues/7826). No duplicate cleanup
PR found.
### Validation
Mobile formatting/static analysis passed. The full existing mobile suite
passed (3,216 tests; 4 skipped), plus the three unconfigured-build tests
and gateway recipe checks. Existing opt-out recovery tests exercised the
switch, persisted tombstone, snapshot synchronization, and successful
relay retry.
Before/after renders use the existing Flutter widget fixture with
synthetic data and mocked native navigation. No simulator or TestFlight
run was performed. After merge, validate the settings row and on/off
flow in the next iOS candidate; remote disable failure remains a
separate investigation.
GitHub CI also passed the mobile tests, unconfigured-build tests, and
gateway recipe checks. The [security
review](https://github.com/block/buzz/actions/runs/37863885299)
completed successfully. The [Android
build](https://github.com/block/buzz/actions/runs/37863554077/job/113605025305)
passed. The iOS simulator build, native accessibility checks, and
unsigned iOS release build passed. [All required CI
checks](https://github.com/block/buzz/actions/runs/37863554077) are
green.
### Before and after

## 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.

## Summary
Preview buzz-app's Tabler icon style in the mobile app, replacing
app-drawn Lucide glyphs across channels, messages, activity, search, and
settings. A shared `BuzzIcons` mapping uses the bundled Tabler 3.46.0
outline font, matching buzz-app's version, with its MIT license and
source documented.
Native UIKit controls retain SF Symbols. The former 300/500 navigation
glyphs use Tabler's standard outline; existing selection colors and
labels remain.
### Related issue
No matching Tabler mobile migration issue or PR found. Related native
iOS controls: #8055.
### Testing
- Pre-push mobile analysis, formatting, file-size checks, and the full
mobile test suite passed.
- 194 focused widget tests passed, including channels, home, search,
settings, and message content.
- Light and dark community-settings renders inspected.
- Signed iPhone Release build succeeded; installed and launched as Buzz
Tabler on a physical iPhone.
- Full `just ci` attempted; stopped during Rust clippy compilation
because the Mac ran low on disk space. Full repository validation is not
claimed.

## 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.

Hide the iOS Notifications settings section for communities that have
not enabled push unless their relay advertises valid push support. A
build with a configured gateway previously showed the switch even when
the relay could not support push.
Communities where push is already enabled retain an off switch and iOS
Settings recovery during discovery or when push support is unavailable.
The section explains that support is unavailable instead of claiming
notifications will arrive.
Capability discovery keeps its existing refresh behavior. Returning
after at least five seconds in the background reconnects the session and
fetches capability again. Tom explicitly chose this behavior without new
retries, polling, or refresh triggers.
Companion client change for squareup/buzz-releases#104. Related: #7826
(broader notification availability diagnostics).
### Validation
Settings widget tests cover hidden first-time opt-in during loading,
absent capability, and discovery errors. Recovery tests exercise the
real off switch for already-enabled communities in all three states,
verifying persisted opt-out, the native snapshot writer, a durable
pending relay tombstone after failure, and the iOS Settings link. They
also verify that pending recovery stays visible after a relay failure
and disappears only after opt-out confirmation. Tests without a gateway
definition verify hidden first-time settings and disabled native
registration. Mobile analysis and the mobile test suite passed.

## Summary
In the mobile app, anyone who hasn't set a display name shows up as a
raw 64-character hex key (e.g. `3a5d4f9c…`) — unreadable, and
unrecognizable as the same identity across screens. Profile and Settings
also let you copy that raw hex. Nostr public keys have a standard
readable form — `npub1…`, the same encoding other Nostr apps and our
desktop app already display. This PR makes every mobile identity surface
render npub instead:
- **Unnamed people everywhere** — message and thread authors, reactions,
typing indicators, member lists, channel details, DM headers and tiles,
inbox, search, forum cards, Pulse notes and reply context, mention
suggestions, and invite rows — now show a compact npub label: first 8 +
last 4 characters of the full npub joined by an ellipsis
(`npub1abcd…wxyz`), the same truncation desktop uses. Previously these
showed truncated raw hex.
- **DM fallback avatars and blank names** — 1:1 DM tiles and headers key
their fallback avatar to the same non-self counterpart the label names,
including self-first participant order; a self-DM keeps its
hex-key-derived initial. Blank or whitespace-only display names fall
back to the compact npub instead of rendering empty, while nonblank
authored names render verbatim (padding included).
- **Profile sheet → "Copy public key"** now copies the full canonical
npub — never raw hex. When the identity string isn't a valid public key,
the copy tile is disabled, so a malformed key never reaches the
clipboard.
- **Settings → Identity (pubkey)** displays and copies the full npub; an
invalid identity reads "Identity unavailable" with copy disabled.
- **Invalid identities never leak truncated raw hex** into the UI
anywhere — they render a neutral "Unknown identity" label.
- **Unchanged on purpose:** display names and verified handles (NIP-05 —
the `name@domain` badge) still render as before. Unnamed avatars keep
distinct per-key initials, derived from the underlying hex key rather
than the npub — otherwise every unnamed key would render the same "N"
initial. Event IDs are not public keys, so they keep their hex
truncation (in Pulse's "Replying to", the parent author shows npub while
an event-id fallback still shows hex). The nevent share link, private
keys, and internal hex storage are untouched. Inputs that accept a key
(invite/member entry) accept both hex and npub and keep working in hex
internally.
### Related issue
N/A. Searched open issues/PRs for npub identity display on mobile —
closest related: none found. Desktop's parallel npub standardization
lives in the stacked desktop PRs (#7488 foundation, #7489 controls,
#7495 display surfaces); this is the independent mobile slice (based
directly on `main`, not on those branches).
### Testing
At exact head `5a620e420a1fd57d9d8011ac26434eed32fcf765` (base: `main`
`44316ff72`; 40 files, +1,345/−154):
- Full mobile suite: 2,098 tests passing (`cd mobile && flutter test`);
`flutter analyze` clean; `dart format --set-exit-if-changed .` clean —
the same checks CI runs.
- Widget/unit coverage at production seams: compact labels and hex-keyed
avatar initials for DM headers/tiles, member rows, mention suggestions,
and Pulse reply context; DM fallback avatars keyed to the labeled
counterpart (self-first order and self-DMs); blank/whitespace
display-name npub fallback with nonblank authored labels verbatim,
including the Activity inbox sender and profile-sheet heading (each with
its own empty/whitespace production-seam regression); full-npub copy and
disabled-copy semantics in profile and settings; invalid-key
suppression; and hex↔npub input round-trips.
Verified via unit and widget tests — no device/simulator validation is
claimed.

This PR implements MVP, iOS-only,
[NIP-PL](8d2d0ff5ad/docs/nips/NIP-PL.md)-compliant
push notifications.
A relay with `BUZZ_PUSH_ENABLED` will send a push notification for any
message that appears in the in-app Notifications tab.
## Enrollment flow

`BUZZ_PUSH_ENABLED`:

```
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.

**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
At `be5620f5f10aa6cc16e86a4f01f102f3d9aeef9b`:
- `cd mobile && ../bin/flutter analyze` — no issues

## Reproduction steps
1. Launch Buzz Desktop with identity-lost state and choose **Recover
from your phone**.
2. Confirm the QR and persistent **Copy pairing code** fallback appear
without layout shift.
3. On a signed-in phone, open **Settings → Send identity to desktop**,
scan or paste the recovery code, and compare the six-digit SAS on both
devices.
4. Confirm on both sides and verify Desktop restores the identity and
continues to harness setup.
5. Repeat from identity-lost state with **Recover from a backup file**;
verify picker and drag-and-drop both advance to password entry and
restore the encrypted backup.
6. Exercise cancellation, mismatched/unsupported codes, expired
sessions, and an invalid backup; verify each returns actionable,
non-stuck UI.
