58eb36dd57 perf(mobile): cheaper identity-name rebuilds for large rosters (#8936)
## Summary

Every identity-name source change (a profile batch, a verified name)
rebuilds a channel's naming scope over its whole member list. In a
4,000-member channel, each rebuild derived every key's naming fact more
than once: owner loading and resolution each derived it, and so did each
label for a key outside the scope. It also checked every key against a
regular expression several times, and iOS AOT builds run regular
expressions in an interpreter.

- `IdentityNames` derives each key's naming fact once per scope.
- `isHexPubkey`: a character-loop hex check, used by the identity-name
code instead of the regular expressions.

Labels are unchanged.

## Measurements

These were taken with an earlier version of this PR that also cached
npub encoding. That cache was removed to keep the change small, so the
remaining gain is smaller than shown. I haven't re-measured it.

- **Synthetic** (Mac, `flutter test`, 4,391 members, 60% with profiles;
scope, `missingOwnerProfiles` and every label for each new sources
object): a warm rebuild took 63 ms before and 12 ms with the cache. The
first rebuild took 120 ms before and 91 ms with the cache.
- **Device** (iPhone 12 mini, Profile build, first 5 s after opening
#announcements with 4,391 members; runs not matched):
`channelIdentityNamesProvider` plus `watchChannelIdentityLabel`
inclusive CPU was 148 ms before and 81 ms with the cache. Of that,
`fullNpub` (npub encoding, the cached part) went from 62 ms to 22 ms.
The identity path no longer calls `RegExp.hasMatch`.

## Testing

- A new test counts profile lookups. Owner loading, every label and an
outside key read each member's profile once. Without the memo, each is
read 3 times.
- New `isHexPubkey` tests cover both cases, wrong lengths, characters
just outside each range, and a bad character at every position.
- `just mobile-check mobile-test` passes.

985de41f14 feat(mobile): show NIP-FI verified names (#8858)
Stacked on #8700. Review only the last commit until #8700 merges.

NIP-FI relays can publish a relay-signed verified name for each member
who signs in with an organization assertion (kind 30382, specified in
#8745 and implemented in the relay in #8774). Desktop shows these names
in block/buzz-app#2005. Mobile showed only self-declared kind 0 names,
so a verified Block name looked no different from one anyone could set.

This adds verified names to mobile, following the spec and the desktop
client's validation rules.

**What people see**

- A verified member's name is the issuer-verified display name wherever
mobile resolves names through identity names (message headers, threads,
DM titles, member lists).
- Message headers and the profile sheet show a verification mark. The
profile sheet also shows the full name when present, "Verified by
{issuer}", "Last verified {time ago}", and marks the record as cached
when it hasn't been reconciled with the relay on this connection.
Verification is described as historical, never as current access.
- Nothing changes on relays that don't advertise
`federated_identity.public_profile`, and marks never come from kind 0 or
NIP-05.

**How it works**

- NIP-11 discovery decides whether marks may show: a successful response
without `public_profile` hides them (cached records are kept), and a
failed or malformed response keeps the last state. Discovery refreshes
on connect and every 5 minutes while names are tracked.
- Subjects are tracked as the profile cache resolves them, and fetched
in batches of up to 128 with `{kinds:[30382], authors:[self],
#d:[...]}`. Live updates and retractions apply on the same subscription.
A full batch that omits subjects is not treated as proof they have no
record.
- Each event's id and signature are verified (in an isolate) before use,
and it must be authored by the community's NIP-11 `self` key with
exactly the specified tags (plus the optional `full_name` the relay
emits). Names follow the spec's NFC and character rules; `unorm_dart`
(MIT, pure Dart) is added for the NFC check because Dart has no built-in
normalizer.
- The cache is per community and is cleared when the relay's `self` key
changes.

**Not yet covered**

- Some surfaces still read the kind 0 name directly: the members sheet
initial, and search and inbox rows. The mark isn't shown in search rows,
inbox rows, or member tiles. (The mention picker now matches, ranks and
inserts by the verified name and shows the mark, and it also offers
cached verified people outside the channel whose kind 0 name differs.)
- NIP-FI says clients MUST show `issuer_label` beside every verified
name. Here it appears only in the mark's tooltip and accessibility label
and in the profile sheet, and verified names reaching DM titles and
member lists show no mark or issuer. Follow-up: show the issuer inline
wherever a verified name is shown.
- Live updates are coalesced to the newest per subject before signature
proof, ordered by unverified `created_at`/`id`. Only a misbehaving relay
could exploit this (the subscription is `authors:[self]`), and it could
already withhold events. Follow-up: prove first, then coalesce among
valid events.
- The verified `username` isn't shown beside the name in message headers
(the NIP-05 handle still is).
- Collision qualification relies on the existing name-disambiguation
policy rather than the spec's exact self-declared-name rule.

### Validation

Added tests:

- Validation: discovery enabled, disabled and malformed; wrong author;
mismatched or duplicate `d`/`p`; extra or duplicate tags; invalid
usernames; non-NFC and whitespace-padded names; `verified_at` after
`created_at`; bad signatures; retractions.
- Directory: discovery gating, batching, truncation, live retraction,
reconnect reconciliation, and disable hiding cached records.
- Directory failures: a pre-EOSE flood, failed proof retried on refresh,
oversized events (by total size, id or signature) dropped before proof,
live events coalesced, a retry before or after the first EOSE never
proving absence, a retry during proof not promoting records to checked,
and a newer signed malformed projection clearing the older one.
- Mention picker: a verified name finds, ranks and inserts the verified
person; the self-declared name still finds them; a verified person
outside the channel is found by verified name even when an impostor
copies that name into kind 0.
- Identity names: a verified name outranks the kind 0 name.
- UI: the mark in message headers and the profile sheet details, no mark
for a cached record, and a single accessible label.

Full `mobile-check` and `mobile-test` pass.

**Live relay (checked 2026-11-01):** not yet run end to end.

- Staging now advertises the feature: the bb-block staging relay's
NIP-11 (`buzz.block.builderlabstaging.xyz`) has
`federated_identity.public_profile` with `kind: 30382` and
`multiple_issuers: false`, bound to `self` `f7f4df94…dcf1`. So #8774 is
deployed and enabled there. The other staging relays
(`communities.public.builderlabstaging.xyz` and its `team.` host)
advertise no `federated_identity`, and the client shows nothing on them.
- I couldn't confirm that real 30382 events are served or render them.
The relay requires NIP-42 auth plus a client-attached NIP-FI assertion,
which needs an interactive Builderlab/Okta sign-in on a physical device.
SSO doesn't work in the iOS simulator. The remaining step is a device
run signed in to the staging Block community, with screenshots of a
verified name, its mark and its details.

**Shipping behind discovery gating:** this is safe. The client reads and
shows verified names only when a successful NIP-11 discovery advertises
`public_profile` bound to `self`. It accepts only kind 30382 events
signed by that key that pass id and signature verification and strict
shape checks. On every relay without the feature, which is every relay
but bb-block staging today, it shows nothing new and changes no names. A
failed or malformed discovery never turns the feature on, and it marks
cached records as unchecked, which hides their mark. The subscription
and reconciliation paths are covered by the tests above, and Carl's
review reran retry probes through the real `RelaySessionNotifier`.

f6f6d9a673 chore(mobile): delete dead code with no remaining UI path (#8880)
## 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.

543ecf2b1f fix(mobile): list the same owned agents as desktop (#8857)
## Summary

Mobile's Agents modal listed agents that desktop does not show. Most
were agents created in the earlier Buzz app (this repository's
`desktop/`), which the owner had not imported into Buzz 1.0
([block/buzz-app](https://github.com/block/buzz-app)). @ completion
offered them as well.

Desktop lists an owned agent only when the owner's newest kind:30177
record for that agent has a `pluginId/typeId` `runtime` tag and a name.
Records written by the earlier app have no `runtime` tag. Importing an
agent on desktop republishes its record with one
([`listingsOf`](662e91800a/src/features/agents/service.ts (L1413-L1460))).
Mobile now applies the same rule:

- **Agents modal:** shows listed owned agents, plus the account's remote
agents that have a verified owner profile here (so one stays listed
while a deletion that already removed its registration is retried).
Owned kind:10100 directory entries no longer add agents on their own.
- **@ completion:** channel members are always offered. Listed owned
agents are offered in streams and forums, where they can be added, as on
desktop. An owned agent that isn't listed is no longer offered from the
directory or from search, because mobile can't import it. The check that
runs before sending a restored draft follows the same rule.

The owned-agent directory moved to `lib/shared/agents` so the channels
feature can use it.

Shared agents owned by other people still come from the kind:10100
directory, which desktop doesn't use for @. That difference is unchanged
here.

### Related issue

None found.

### Validation

iPhone 17 simulator, debug build, against a local relay seeded with one
owner and two owned agents. Both agents have a NIP-OA profile. "Current
Agent" has a desktop runtime tag. "Old App Agent" has a registration
written the way the earlier app writes it, with no runtime tag. The
before captures are `origin/main` with the same data.

| ![Search after: nothing
offered](https://github.com/user-attachments/assets/47246f69-e939-402d-acfc-d0c764df967c)
|

Added tests:
- Directory loading: remote, desktop, earlier-app, later-imported, and
reverted agents, plus agents owned by someone else; only the newest
record counts. A table test covers the runtime and name rule.
- Agents modal widget test: an earlier-app agent is not shown.
- Mention candidates: only listed owned agents are offered outside the
channel, including from search.
- Compose bar: a restored draft that mentions an unlisted owned agent
outside the channel is rejected before sending.

I disabled the runtime check and the unlisted-agent filter, and the four
new guarding tests failed. The full mobile suite passes.

Human test: not applicable for this mobile change under the author's
standing exception.

7e8aac4403 fix(mobile): polish channel management and iOS Settings (#8171)
## 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.

4ef23609b7 feat(mobile): show contextual names in channel conversations (#7895)
🤖
## Summary

In a channel conversation, two identities with the same display name
looked identical. In the example below, the channel shows "Bad Janet"
twice, for two different identities. A reader cannot tell which one was
added and then removed.

This PR uses the contextual names from the previous PR everywhere a
conversation names someone:

- Message authors, threads, forum posts and replies
- Reactions, the typing indicator, and system rows (joined, added,
removed)
- Inline mentions and the agent activity sheet
- The profile sheet title, which now matches the row that opened it

Names are compared against the channel's members, so a label only gets
longer when a real collision exists in that channel.

The mention picker labels each choice against every candidate, so two
"Honey" choices look different. When you pick one, it still inserts the
identity's own name ("@Honey"), so the message text does not change.

Part 2 of 3: #7894 (resolver) → #7895 (conversations) → #7896 (lists,
Search, Pulse).

### Related issue

Related to #2910.

### Testing

- A widget test checks that the profile sheet names an author the same
way the channel does.
- A unit test checks that two same-name mention choices get different
labels but insert the same wire name.
- `flutter analyze` is clean, and the full `flutter test` suite passes.
- Checked on an Android emulator against the live relay, in an archived
channel with two identities named "Bad Janet".

efe04288ea feat(mobile): add the contextual identity-name resolver (#7894)
🤖
## Summary

When two identities share a display name, Buzz mobile shows the same
label for both. A reader cannot tell a person from an agent, or one
person's agent from another's. For example, a channel can show three
agents and one human all named "murderbot".

This PR adds the naming rules that fix this, without changing any screen
yet. It ports the contextual identity-name contract (v1) from the
desktop app to Dart. Given the identities shown together, the resolver
gives each public key a distinct label:

- A human keeps the plain name. Agents that share it get a qualifier.
- The viewer's own agents are named before other people's agents.
- An agent is qualified by its owner's name first ("Wes's Honey"). A
short public-key suffix is added only if that is still ambiguous
("baxen's murderbot · xa8v").

It also adds two providers that screens will use:

- `channelIdentityNamesProvider` compares names against a channel's
members, plus any referenced non-member such as an old author or an
outside mention.
- `watchIdentityNames` compares a set of identities shown together
outside a channel, and loads their profiles.

The next PRs in this stack connect these to the screens.

Part 1 of 3: #7894 (resolver) → #7895 (conversations) → #7896 (lists,
Search, Pulse).

### Related issue

Related to #2910 (default "Fizz" agents from different users collide in
one channel).

### Testing

- The contract's 31 portable fixture cases run against the production
resolver. The fixture file is copied unchanged from the contract, so
reviewers can skip it.
- Unit tests cover owner and suffix qualification, the viewer's own
identities, and invalid public keys.
- Provider tests check that a channel keeps its names while its roster
reloads, that an offline cached bot still counts as an agent, and that
changing relay or account never shows the old roster.
- `flutter analyze` is clean.

No UI change, so there are no screenshots.
