52cb6818fa perf(mobile): keep remote images on disk and show small ones as thumbnails (#9158)
## Summary

The mobile app now saves remote images on disk. After a relaunch,
avatars, custom emoji, message attachments and agent artwork show
immediately. The app does not download them again.

Small images on a relay now load only the relay's thumbnail. The app
never downloads the full-size upload to show a small image.

## Why

Before this change, the app kept remote images only in memory. Each cold
launch downloaded every image again. On a slow connection, attachments
showed a "Loading image" placeholder for a long time.

Also, when a relay had no thumbnail for an image, the app downloaded the
full-size upload. That upload can be up to 20 MiB, for an avatar that is
a few dozen points wide.

## What changes

### Images on disk

- `MediaImageProvider` reads and writes a `MediaDiskCache`. Each account
in each community has its own cache, at `<root>/communities/<community
id>/media/<signer pubkey>`. The cache is built on
`flutter_cache_manager`, with a JSON index.
- On iOS, the root is the app group's `Library/Caches` (from a new
`buzz/app_group` method channel). App extensions can then read the same
cache. On other platforms, the root is the app cache directory.
- Each cache holds a maximum of 250 MB. When it is full, the least
recently used images go first. `MediaCacheIndex` measures each file when
it writes it, because `flutter_cache_manager` limits only the number of
files. Every disk read marks the file used, and every write schedules
eviction, including a refresh that replaces bytes the package already
holds in memory (by default the package does neither for those).
- The cache does not save an image that is larger than 5 MiB. The app
still shows that image from memory. Thus, one large image cannot push
out all the others.
- Relay media URLs contain a content hash, so their bytes never change.
The cache keeps them until it evicts them. For other URLs, the cache
shows the saved image, and then gets a new copy in the background after
one week. A maximum of two of these refreshes run at the same time. The
app decodes a refreshed image before it replaces the saved copy.
- When you remove a community, the app deletes its cache. When a
community gets a new signing key, the app deletes the media of the old
account. At launch, the app also deletes caches of communities and
accounts that are no longer present.
- Startup does not wait for the cache. The cache directory resolves in
the background. Image reads wait for it for a maximum of 3 seconds.

### Thumbnails for small images

- A small relay image loads the relay's WebP thumbnail. If the relay has
no WebP thumbnail, the image loads the JPEG thumbnail. If the relay has
neither, the widget shows its placeholder (initials for an avatar, an
empty tile for artwork).
- Native avatars drawn by UIKit (the navigation bar, the community icon
on the create button, and the New DM and Add Members pickers) use the
same choice, through a new `smallMediaImageProviders`. They try the same
thumbnails, fall back the same way, and show initials when neither
thumbnail exists. Before, they downloaded the full-size upload and only
decoded it small.
- Larger layouts and the full-screen viewer load the full-size upload,
as before.

### Agent artwork

- Preset agent artwork (the tray, flight, video placeholder, avatar hero
and the avatar editor's blurred backdrop) now loads through
`MediaImage`, so it uses the disk cache too.
- The create-agent and empty-bestie pages warm the same
`MediaImageProvider` that their widgets read, through a new
`mediaImageProviderFor(ref, url)`.
- No code in `mobile/lib` uses `Image.network` or `NetworkImage` now.

## Demo

A cold relaunch (the app is stopped, then started) into a synthetic "QA
demo" Solo chat that holds a few generated images. Shown at half speed.

Before: the attachment shows a "Loading image" placeholder while it
downloads.


https://github.com/user-attachments/assets/107f43a3-63d0-40c3-bd80-4ea9d7897a97

After: the attachment shows with the chat, from disk.


https://github.com/user-attachments/assets/d3985bb2-838c-4efa-93cb-44cef51f677d

## Tests

- `test/shared/relay/media_disk_cache_test.dart` follows one journey
through the real provider and a real cache in a temporary directory. The
first launch downloads and saves. An offline relaunch shows the
full-size image, its thumbnail and an external image from disk, and the
oversized image goes back to the network. Eight days later, only the
external image refreshes. Removing the community deletes its directory.
- A second test checks the order of eviction when the cache is full,
that a file read from disk is evicted after files that were not, and
that replacing a file's bytes after eviction last ran evicts again when
the cache goes over budget.
- `community_provider_test` checks that launch deletes orphan media
directories, that a new signing key deletes only the old account's
media, and that removing a community deletes its media.
- `avatar_image_test` checks that a missing WebP thumbnail falls back to
the JPEG thumbnail, and that an avatar with no thumbnail shows its
initials.
- `native_avatar_image_test` checks the same for native avatars: a WebP
404 paints the JPEG thumbnail, the full-size upload is never requested,
a relay with no thumbnail paints initials and is not asked again, and
any other failure stops at the initials.
- `flutter analyze` and the full mobile test suite pass.
- Automated app runs on an iPhone 17 Pro simulator (iOS 27): the channel
list, a DM, Home, the Agents grid and an agent details sheet show their
images. After a relaunch, the images came from disk and the app wrote no
new files. In the "QA demo" chat, a new image from the app showed
immediately.
- Automated run of the native-thumbnail fix on an iPhone 17 Pro
simulator (iOS 27): the native New DM picker shows photo avatars, and
the cache gained only relay `.thumb.webp` entries for them, no full-size
uploads. After a cold relaunch, the picker showed the same avatars
within about 1.5 seconds, and the cache directory gained no files. The
avatar editor backdrop was not exercised in the app. The test community
has no remote agents, and the backdrop tests cover only emoji and
picked-image selections.

## Before merge

- [x] Automated simulator run of this head: avatars and agent artwork
show their thumbnails, and a cold relaunch shows images from disk.

f38285562c fix(mobile): read only shown events from filtered Activity rows (#9215)
## Summary

Follow-up to [#9213 Activity filters
UI](https://github.com/block/buzz/pull/9213), from its [last Codex
finding](https://github.com/block/buzz/pull/9213#discussion_r4497322772).

With Threads, Mentions or a People/Agents filter active, an Activity row
holds only part of its conversation. Marking it read advanced the
`thread:<root>` (or channel) marker through the row's latest event,
which also read replies the filter hid. For example, reading a person's
reply in People also read an older agent reply in the same thread.

Filtered rows now advance the synced thread or channel marker through
every event that is read, stopping just before the first unread event
the filter hides, and write local `msg:` marks only for shown events
past that point. Once the hidden event is read too, the marker catches
up and syncs both. This also fixes filtered DM rows from #9213, whose
`msg:`-only reads never synced to other devices. Unfiltered rows are
unchanged.

## Testing

- New widget test: "reading a thread row under People leaves hidden
agent replies unread". It fails without the fix, and checks the synced
marker stops short of a hidden unread reply, then advances fully once
nothing hidden is unread.
- `flutter test test/features/activity/` (136 pass) and `flutter
analyze` on the activity feature.

## Before merge

- [x] Automated simulator run (iPhone 17 Pro sim, iOS 27, re-run on
d17f79a; the catch-up change in 28b927e is covered by the widget test):
with Agents selected, marked a channel mention row unread then read; it
stays read under Anyone and after relaunch. Screenshots are in Buzz
(internal data). The test account has no thread mixing agent and human
replies, so the hidden-reply case is covered by the widget test.
- [x] Main vs PR simulator comparison of a filtered thread read with a
hidden unread reply (iPhone 17 Pro sim, iOS 27; main at
[65e8643](https://github.com/block/buzz/commit/65e864301d), PR at
[b2414cf](b2414cf6d8)).
Neither test account has a real thread with both a person and an agent
mention, so this runs the Activity page on the simulator with seeded
events through the widget-test harness (`flutter run` of the test). The
thread has an older agent mention and a newer person mention, both
unread. The steps: choose People, swipe the person row to read it,
switch to Agents, then Anyone. Left is main, right is this PR.
  - After the read, the person row is read under People on both.
- Under Agents, main shows the older agent reply as read (the thread
marker moved to the person reply's timestamp). The PR keeps it unread
(marker stops one second before the agent reply).


![cmp-4-agents-after](https://raw.githubusercontent.com/block/buzz/aa95e2b22a6ac7815ba1ba36453c0c6c3a994bec/pr-9215--cmp-4-agents-after.png)
- Under Anyone, the thread row is read on main and still unread on the
PR, because its agent reply is unread.

e1e1cd50ab fix(mobile): keep Home's header clean under sheets (#9152)
On iOS, opening a sheet over Home (for example a channel's long-press
actions) left a hard horizontal edge and a light glow band under the
filter chips. Home's header keeps a native UIKit soft-edge view behind
its Flutter controls, and the sheet's dim barrier doesn't composite
cleanly over it.

While another route covers Home, the header now switches to its Flutter
backdrop through the existing `FrostedAppBar.nativeViewSuppressed` hook,
the same mechanism other headers use while a backdrop covers them. Home
already hides its native bottom controls under the same condition.

| Before | After |

src="https://github.com/user-attachments/assets/6813bb27-9f76-45d5-81c3-b46d8e0df647"
width="300"> |

### Validation

- iPhone 17 Pro simulator (iOS 27), Builderlab test community:
reproduced the artifact on `main` with Home scrolled and the channel
actions sheet open, then confirmed it is gone with this change. Also
opened and dismissed the sheet repeatedly and checked the header before,
during and after.
- Transition timing, frame-stepped from simulator recordings of `main`
(top row of each strip) and this PR (bottom row) on the same Home state:
- The header and the bottom navigation controls switch on the same
frame. A modal sheet doesn't drive Home's secondary animation
(`MaterialPageRoute.canTransitionTo` is false for a sheet route), so the
bottom controls' `secondaryAnimation == 0` check reduces to the same
`isCurrent` gate the header uses.
- Known limitation: while the native header view is swapped out, the
header blanks for about 2 display frames as the sheet opens and about 3
as it closes (about 30 to 50 ms, seen as the missing chips below).
`main` has no blank frames but shows the hard edge.

  Opening:

<img alt="sheet open, main above PR"
src="https://github.com/user-attachments/assets/df8f04f2-da72-4889-b9c8-5c47596fe7e3"

src="https://github.com/user-attachments/assets/aa234a82-773d-4c9f-bba4-469afd158de8"
width="900">
- Extended the iOS Home widget journey: the native header view is
removed while the channel actions sheet is open and restored after it is
dismissed. Without the fix, the journey fails.
- Full mobile Flutter suite passes.

ac2c5831f3 fix(mobile): show already-loaded custom emoji in the iOS reactions sheet (#9150)
On iOS, the reactions sheet (long-press a reaction pill) could show a
custom emoji as truncated `:shortcode:` text, for example `:eye…`, even
though the same emoji rendered as an image on the message pill a moment
before.

The sheet is a native UIKit view that downloaded each custom emoji again
with its own `URLSession` request and showed the shortcode label until
that download finished, and for good when it failed. A shortcode is
illegible in a chip that size.

Now:

- Flutter keeps the encoded bytes of custom emoji it has downloaded (a
bounded LRU: 512 KiB per emoji, 8 MiB total, rebuilt when the media auth
scope changes so accounts never share bytes) and hands them to the
sheet, which decodes them without a fetch. Emoji the timeline never
loaded still download natively as before.
- A custom emoji in the sheet never shows its shortcode: it stays blank
while loading and shows the sparkles icon, matching the native emoji
picker, if the image cannot load. Reaction pills in Flutter get the same
sparkles fallback. Inline emoji in message text keep the shortcode
fallback, where it reads as text. Avatars in the sheet keep their
initial.

### Before / after

Reactions sheet header and chips right after opening, on a message with
two custom-emoji reactions (synthetic test channel, captured from a 30
fps screen recording).

| Before (main) | After (this branch) |
| --- | --- |
| <img width="300" alt="Before: custom emoji chips show truncated
:qa-... shortcodes"
src="https://github.com/user-attachments/assets/593e555b-9c82-4eec-9049-3d909f987c76">

src="https://github.com/user-attachments/assets/a6739997-b39f-4062-9e5c-d22a8a38b368">
|

### Validation

- Added tests: the native sheet's payload carries the bytes the pill
already downloaded; the combined reaction tray shows sparkles, not the
shortcode, when a custom emoji fails to load (the existing alignment
test previously asserted the shortcode).
- Full mobile suite and `just mobile-check` pass; the iOS simulator
build compiles.
- Automated simulator run (iPhone 17 Pro, iOS 27, main vs this branch,
signed in to a test community): channel list, opening a channel, the
message action sheet, the emoji picker, and the reactions sheet on a
message carrying two custom emoji I added plus a thumbs-up. On main the
sheet's custom-emoji chips show truncated `:qa-...` shortcodes for a few
frames before the images arrive; on this branch they render as images
from the first frame (see Before / after). Limitations: the emoji images
load fine over the network in this setup, so the failed-download
sparkles fallback was covered by tests only, not seen in the app; a long
press on the combined reaction tray opened the message menu in the
simulator, a tap opened the sheet.

40cfa72cd4 mobile: add follow and remind actions to inbox row menu (#9142)
Long-pressing an Inbox row opened a sheet with only **Mark as
read/unread** and **Open conversation**. To follow a thread or set a
reminder, you had to open the conversation and long-press the message
itself.

The row sheet now also offers:

- **Follow thread / Unfollow thread**: acts on the conversation's thread
root, or on the message itself for a top-level row (the same rule the
message actions sheet uses). It's hidden for Solo chats, which have no
threads, and for grouped DM conversations, which have no single thread
to follow.
- **Remind me**: opens the existing "Remind me later" sheet for the
row's latest message and publishes the same kind-30300 reminder. If that
message already has a pending reminder, the new time reschedules it: the
event reuses its `d` tag (an addressable replace) and keeps its note, so
you don't get a second reminder. It loads the reminder list first,
because otherwise the list loads only with the Reminders filter. It's
hidden when signed out, like the message sheet.

The sheet is now scrollable so the four rows fit on short screens and at
large text sizes (without it, the new test overflowed at the default
test surface).

### Demo

Long-press a channel mention row in the Inbox, follow the thread, reopen
the sheet (now **Unfollow thread**), then set an "In 1 hour" reminder.
The rows are agent test chatter from a pilot community.


https://github.com/user-attachments/assets/ad94e5f2-1048-4585-9663-145e814892e3

### Validation

- Added tests: one Activity page journey that follows and unfollows a
thread row, follows a top-level row, then sets a reminder through the
sheet and checks the published target (event, channel, preview). Further
tests cover rescheduling an existing pending reminder (same `d` tag,
note kept, "Reminder updated"), hiding Follow in a Solo chat, and hiding
Remind me when signed out. The `test/features/activity`,
`test/shared/reminders` and message-actions suites pass.
- Re-run on the branch head (99b2418) in an iPhone 17 Pro simulator (iOS
27) debug build, same community: long-pressed a thread-capable channel
mention row, tapped **Follow thread**, reopened the sheet and saw
**Unfollow thread**, tapped **Remind me** and then "In 1 hour", and saw
the "Reminder set" toast (this is the video above). Long-pressing a Solo
chat row showed no **Follow thread** row, as intended. Not covered on
the simulator: rescheduling an existing reminder, signed-out state,
large text sizes. Those are covered by the widget tests.
- Automated app run on an iPhone 17 Pro simulator (iOS 27) signed in to
the Remote Agents Pilot community: opened Inbox, long-pressed a channel
mention row, followed the thread, reopened the sheet and saw **Unfollow
thread**, then set an "In 1 hour" reminder and saw the "Reminder set"
toast. That run predates the reschedule and Solo changes, which are
covered by the widget tests above. I didn't re-run unrelated Inbox flows
(swipe to mark read, filters) on the simulator. Those are covered by the
existing widget tests.

ad5699d05a fix(mobile): start no threads in Solo chats (#9123)
Agents in a Solo chat always answer at the chat's top level. On mobile
you can still start a thread in Solo (Reply action, swipe-to-reply,
media reply) or reply inside an existing one, so the agent's answer
lands outside the thread you wrote in. Desktop already avoids this: Solo
shows existing threads but starts none and has no thread composer.

This matches desktop on mobile:

- No Reply quick action, swipe-to-reply or media reply in Solo chats.
- Existing Solo threads still open from their reply summary, read-only
(no composer).
- Every other channel is unchanged.

### Demo

Synthetic Solo chat "QA demo", iPhone 17 Pro simulator. Each clip: right
swipe on an agent message, then long-press for the actions.

Before (main): the swipe shows the reply circle and opens a thread with
a composer; Reply is in the actions.


https://github.com/user-attachments/assets/cc5025a3-b7ba-4ab2-bebb-06c7b54e7906

After (this branch): the swipe does nothing; the actions have no Reply.


https://github.com/user-attachments/assets/b31f9983-8c52-45c2-ae88-1661aa71210e

### Validation

Added tests: a Solo chat's message neither swipes to reply nor offers
Reply in its actions, and a Solo thread opens without a composer.
Existing swipe-reply and Solo channel tests pass, along with the full
mobile suite and analyzer.

Simulator run on an iPhone 17 Pro, signed in to a real community: in an
existing Solo chat, a right swipe on an agent message no longer moves or
opens a thread, and the long-press actions show no Reply (Copy link,
Remind me and the rest are unchanged). Team-channel Reply is covered by
the existing swipe-reply tests, not this run.

A second simulator run on an iPhone 17 Pro, in a synthetic Solo chat,
compared main and this branch: on main the swipe opens a thread with a
composer and the actions list Reply; on this branch neither does (see
Demo). The Demo's "Follow thread" action still appears in a Solo chat's
actions on both builds; this PR does not change it.

439d7bcc12 fix(mobile): keep a sent thread reply above the composer (#9026)
Fixes two thread symptoms that come from the same state: after sending a
reply, the composer clears but the new reply sits hidden under the
composer (or out of view entirely) until you leave and return, and the
**Latest** button stays visible even though the list looks like it is at
the bottom.

### Cause

1. A sent reply grows into place over its 500 ms entrance transition
(`LocalSendRow`). The thread's one-shot tail correction can finish while
the row is still growing. Once it has finished, nothing moves the list
as the reply keeps growing, so the list stops short of the real end
(about 40 pt on an iPhone 17 Pro simulator) and the reply ends up behind
the composer. Because the list isn't actually at its end, **Latest**
shows. It is visible even with the composer focused when an earlier drag
detached tail-follow.
2. A thread opened at a specific reply (from Inbox, a push notification
or a message link) skipped the new-reply follow logic for its whole
lifetime, not just for the replies it opened with. If the reader
scrolled at all before replying, their own sent reply was never brought
into view: it landed below the viewport, and a quick swipe couldn't
reach it before the next layout.

### Fix

- While the thread follows its tail, a `ScrollMetricsNotification`
listener keeps a position that was at its previous end on the new end
whenever the extent grows. It only acts when the last reply is laid out,
the reader isn't dragging or opted out, and no navigation to the tail is
in progress, so programmatic jumps away from the tail are left alone.
This also covers other growth at the tail, such as media or typing rows.
- A targeted entry now absorbs the replies it hydrates with until its
target jump has revealed the list. Hydration can come in two steps (the
route's snapshot of the target, then the relay's full thread). Absorbing
only the first let the second, when it held the reader's own earlier
replies, schedule a tail correction that cancelled the one-shot target
jump and left the list hidden behind its loading placeholder. Later
arrivals use the ordinary rules: the reader's own reply comes into view,
and other people's replies still don't move a reader who is away from
the tail.

### Before and after

Same flow on an iPhone 17 Pro simulator, in a synthetic QA channel
thread: scroll the list away from the bottom, focus the composer, send a
long reply that wraps onto many lines. Before (main) the sent reply ends
with its bottom edge under the composer; after (this branch) it ends
clear above it.

Before (main):


https://github.com/user-attachments/assets/5101b63d-e2df-46d1-bfd1-49038330ddf5

After (this branch):


https://github.com/user-attachments/assets/1df81ad5-bb6b-4df6-b4e3-5c37fd8aab67

### Validation

- Test `a sent reply stays above the composer as it grows in` now runs
for a plain entry, a targeted entry (`initialMessageId`), and a targeted
entry whose relay hydration is delayed and includes the reader's own
replies. The targeted row opens at an older reply, checks it is visible,
drags a little, focuses the composer with the keyboard up, sends a
multi-line reply, and checks that the reply ends above the composer and
**Latest** is hidden. Each row fails without its fix (growth: reply
bottom at 504, composer top at 402; targeted: the reply is never
followed; delayed hydration: the target never becomes hit-testable
because the list stays hidden).
- Full `flutter analyze` and mobile test suite pass.
- Before/after capture on an iPhone 17 Pro simulator (iOS 27, debug
builds of this branch head and of current main), in a synthetic QA
channel thread with enough replies to scroll. Flow: scroll away from the
bottom, focus the composer, send a long wrapping reply. Over 7 runs on
main, the reply's bottom ended 3 to 25 pt under the composer in 5; over
6 runs on this branch, it ended 17 pt above the composer every time.
Limitation: debug simulator builds only, and the shortfall on main
varies run to run.
- Automated full-app run on an iPhone 17 Pro simulator (iOS 27) against
the Remote Agents Pilot community. In a test DM thread, I sent short and
wrapping replies with no prior scroll, after dragging up and returning,
and after the follow-up narrowing. Each reply ended fully above the
composer, and **Latest** stayed hidden at the bottom. I also dragged up
with the keyboard dismissed and confirmed the list stays at the tail
with no stray **Latest**. For the targeted entry, I opened a thread from
a message link, scrolled, and sent replies: without the targeted-entry
fix they stayed out of view under the keyboard; with it hot-reloaded
they were followed (the combined build is covered by the widget test
rows above). I then reopened that link right after an app restart, which
hydrates in two steps: before the hydration fix the thread showed only
its root with the replies hidden, and with it the list revealed at the
target and a sent reply came into view. Human testing is waived per the
owner's standing exception. Limitation: this run did not cover physical
devices or media replies.

The simulator recording was taken in an internal community, so it is
shared internally rather than embedded here.

8cce12f591 feat(mobile): consolidate Solo chat settings in one sheet (#9255)
## Summary
Replace the Solo chat header controls with an ellipsis that opens Chat
settings, showing the selected agent’s avatar and workspace. Agent and
grouped Workspace pickers share one backdrop; closing either returns to
settings without flickering. The sheet smoothly resizes to fit each page
and respects Reduce Motion.

### Related issue
No duplicate found.

### Testing
Full pre-push checks pass without exclusions: analysis, formatting,
file-size checks, all 4547 mobile tests (67 skipped), push-configuration
tests, and secp256k1 tests. Navigation, backdrop continuity, smooth
resizing, and Reduce Motion are covered. Updated four stale link-swipe
tests to use the leftward reply gesture introduced in #9127. Installed
on iPhone Air with saved state preserved.

d839d3731a fix(mobile): swipe left to reply so swipe-back keeps rightward drags (#9127)
Swipe-to-reply used a rightward drag, the same direction as iOS
swipe-back. A rightward drag that started on a message armed a reply
instead of going back, and the reply recognizer claimed horizontal drags
in either direction once they started on a bubble.

Now a message slides **left** to reveal Reply on its trailing side, and
the reply recognizer only wins the gesture arena for leftward drags.
Rightward drags that start on a message are left to back navigation. The
threshold, haptic, rubber-band resistance and thread destination are
unchanged. On bubbles that reach the row's trailing edge (your own
messages), the Reply feedback is kept on screen beneath the bubble, so
the slide uncovers it.

### Demo

Before (main): a rightward drag that starts on a message arms Reply and
slides the bubble, instead of being left to back navigation.


https://github.com/user-attachments/assets/f149cd11-c326-466c-a17b-3e4698708af8

After (this PR): a rightward drag on a bubble does nothing, a leftward
swipe reveals Reply and opens the thread, and edge swipe-back returns to
the channel.


https://github.com/user-attachments/assets/539a5682-1032-452e-a57b-6f27abfe2d64

### Validation

- Focused existing validation: the swipe-reply widget tests were
mirrored to the new direction for channel and thread rows, own and
incoming messages. They now also check that a rightward drag starting on
a bubble reaches an outer horizontal drag handler (a stand-in for
swipe-back) without moving the row or opening a reply. The Bestie DM
test's reply drag was flipped too.
- The full mobile suite (`just mobile-check` and `just mobile-test`)
passes.
- Automated simulator run (iPhone 17 Pro, debug build): swiped left on
outgoing and incoming bubbles (feedback shows on the trailing side,
thread opens), edge swipe-back from a thread and channel, and a
rightward drag starting on a bubble (no reply). The demo above was
recorded on a synthetic private channel (own messages only;
incoming-message rows were covered in the earlier run and by the widget
tests). Human testing is waived under the owner's standing exception.

a7a534d476 mobile: long-press a message link for open, copy and share (#9135)
Holding a link in a message used to open the whole-message actions
sheet, so there was no way to copy or share just the link. Now a hold on
a link opens a small **Link** sheet showing the URL with **Open link**,
**Copy link** and **Share link**. Web links share as URLs so the share
sheet can preview them; other links (such as `buzz://`) share as text.
Open link appears only for destinations the app can open (web and
`buzz://` links), so a `mailto:` link offers Copy and Share. Repo, PR
and issue chips, which have no mobile destination, also offer Copy and
Share on hold. While a finger is down, the link gets a light tint behind
it, the same kind of press highlight the message row paints. A hold
anywhere else in the message still opens the message actions, and a tap
on a link still opens it directly.

The link gets its own long-press recognizer with the same hold deadline
as the message row. Pointer events reach the deeper recognizer first, so
at equal deadlines the link wins the arena before the message row, the
same mechanism reaction pills already use to claim their own hold.
Rendering is otherwise unchanged: the link widget tree only gains a
`RawGestureDetector`, a `Semantics` wrapper and a `DecoratedBox` for the
tint, press state lives in the link widget so only the link rebuilds,
and the sheet is built only when opened. Open reuses the existing tap
path (external browser, authenticated relay-media download, or Buzz deep
link).

### Validation

Added tests: a journey in `message_content_test.dart`, run with both iOS
(200 ms) and Android (default) hold timing, that holds surrounding text
(message menu opens, link sheet doesn't), holds the link (link sheet,
not the message menu), copies it (clipboard gets the URL), opens it from
the sheet and by a plain tap, and checks the press tint appears on touch
and clears when the finger moves away. Removing the link recognizer or
the tint makes it fail. Another test holds a `mailto:` link and checks
the sheet offers Copy and Share but not Open. Swipe-to-reply tests in
`swipe_reply_tests.dart` drag a message starting on its link and beside
it, with both hold timings, and both open the reply.

Full `just mobile-check mobile-test` passes (after rebasing onto main,
two `hosted_backup_service_test.dart` tests failed once under load and
pass on rerun; this PR doesn't touch that code).

Automated app run on an iPhone 17 Pro simulator (iOS 27) signed in to a
Builderlab community, in a private QA channel: held message text
(message actions sheet, dismissed and composer focus restored as
before), held a link (Link sheet), Copy link (toast, simulator
pasteboard holds the URL), held again and Share link (system share sheet
with the page preview). The simulator's share sheet then stopped
responding to dismissal, a known simulator share-extension quirk
unrelated to this change. After adding the tint, a second simulator run
held the link and captured the pressed state (below). Not covered:
Android device run, VoiceOver.

e86d0e23a3 feat(mobile): long-press a Solo chat to open its details sheet (#9163)
Long-pressing a team channel in the Messages list opens a bottom sheet
of channel actions. Long-pressing a Solo chat did nothing, so its
settings (star, mute, members, move, copy, leave/archive/delete) were
only reachable from inside the chat.

Now a long-press on a Solo chat row opens that chat's details screen as
a sheet, with the same presentation as the team channel sheet: drag
handle, close button, 640 pt max width, 70% max height. The content is
the existing channel details page rendered without its app bar
(`ChannelDetailsPage(inSheet: true)`), so it stays in sync with the full
page. Tapping a chat still opens it as before.

Solo chats are placed in Solo workspaces, not channel sections, so their
details (sheet and full page) no longer show "Move to section…". That
row wrote channel sections, which left the chat where it was. Moving a
Solo chat between workspaces stays on the chat header's workspace
control.

### Demo

Long-pressing a Solo chat in the Messages list (Solo filter) opens its
details sheet; Star toggles, the sheet scrolls to the lifecycle actions,
and the close button dismisses it. Synthetic chat named "QA demo".


https://github.com/user-attachments/assets/e8b8a799-be1f-4d4b-b47d-f2209e2b1920

### Validation

- Added test: long-pressing a Solo chat on the Me page opens the details
sheet with the chat's name, the sheet scrolls to its lifecycle actions,
and the channel-section move is absent.
- The full mobile test suite and `flutter analyze` pass.
- Full automated simulator run on the final code (iPhone 17 Pro, debug
build, signed-in Builderlab account, light and dark mode). In the Solo
long-press sheet: Star and Mute toggle and revert; Edit, a member's
profile and Add members open and close back to the sheet; Copy channel
name and Copy channel ID copy the right values and show a toast; the
sheet scrolls; the Leave, Archive and Delete confirmations appear and
were cancelled; the close button, scrim tap and drag down all dismiss
it; "Move to section…" is absent. Tapping the chat still opens it, and
its in-chat details page also omits the section move. Regression check:
the team channel long-press sheet and team details page are unchanged,
including a working "Move to section…". The recording is in Buzz rather
than here because it shows internal channel names. Limitation:
destructive actions were cancelled, not confirmed.

f3b127e3af fix(mobile): keep Home bell tappable while scrolled (#9241)
## Summary
Keep the mobile Home bell tappable while scrolling. Reserve both header
buttons’ space as soon as the filters overlap the toolbar, and clip
filter overflow.

### Related issue
No matching open issue or PR found.

### Testing
- `just mobile-check` and `just mobile-test` passed.
- Android/iOS regression coverage checks the bell at five scroll
positions and Activity navigation. iOS uses platform-view hit testing
plus its callback; no physical-device verification.
- Pre-push checks passed. The additional `just ci` run passed workspace
Rust lint and desktop source checks; stopped during desktop native
dependency compilation, so full local CI is incomplete.

12f3d51001 feat(mobile): one Builderlab per build, internal and public distributions (#9224)
The mobile app can now be built as a public build or an internal build,
set explicitly with `BUZZ_DISTRIBUTION=internal|public`. Each build
trusts exactly one Builderlab (`BUZZ_BUILDERLAB_URL`), and sends that
Builderlab's relay assertions only to the relays in
`BUZZ_BUILDERLAB_RELAYS`. The three settings are set together or not at
all; with none set, the app is a Nostr-only development build. The
decision is recorded in
`docs/adr/0001-internal-and-public-mobile-builds.md`, and the terms are
defined in `CONTEXT.md`.

Before this change, one build supported a public Builderlab and an
organization Builderlab at the same time, with two sessions. An
organization's members could reach public communities from the
organization's app.

### Behavior

- **Public build:** QR pairing, email sign-in and multiple communities
are unchanged. It has no knowledge of any organization. An
organization's relay already rejects clients that can't present its
Builderlab's assertion, and the public build relies on that.
- **Internal build:** the first screen has a single **Sign in** button
that goes straight to the organization's single sign-on and then joins
the organization's community. There is no QR pairing, community link or
community creation, and the community switcher is hidden. Only the exact
relay hosts listed in `BUZZ_BUILDERLAB_RELAYS` are reachable.
- **Identity (internal):** a member whose account has no Nostr identity
yet gets a new key on first sign-in; the first relay assertion binds it,
and the app backs it up to the organization automatically. A member
whose account is already bound uses that key from this device, or
restores it from the organization's backup. If neither is possible, Sign
in says it couldn't restore the identity and saves nothing.
- **Sign-out (internal):** a destructive **Sign out** row at the bottom
of Settings, the build's only way out. It removes the community, closes
Settings and returns to Sign in. The Builderlab session is cleared from
storage immediately and can never be reused to sign back in. The relay
push-stop keeps the retired credential in memory only, for up to 10
minutes, and uses it only to get an assertion for a key that is already
bound. It is a best-effort request.
- **Upgrade to an internal build:** a saved public Builderlab session is
cleared. Communities on other relays are hidden, not deleted, and their
keys stay on the device.
- `BUZZ_HOSTED_RELAY_AUTH` is unchanged here.

### Screenshots (internal build)

| ![Settings ending with a red Sign out
row](https://github.com/user-attachments/assets/f3d60dc1-8170-45e3-a16d-0a1156fdae1a)
|

Gateway-side push revocation, which needs no Builderlab session, is
planned as a separate PR.

### Validation

Added tests:
- An internal-build journey: one Sign in creates and binds a key, and a
retry after a cancelled join reuses it. The app uploads that key's
backup itself. Sign out from Settings closes it and returns to the
landing, which ends the session, and Sign in then restores the same
identity from the backup. Communities on other relays stay stored but
hidden.
- Internal Sign in for a bound account: the key on this device, a key
restored from backup, and no backup (clear error, nothing saved). Each
guard was shown to fail when removed.
- Organization relay assertions: assertions go only to exact listed
hosts, not subdomains. After sign-out, only a push stop for a bound key
gets an assertion, and nothing can sign back in. Proven to fail without
the fix.
- Builderlab build setting parsing.

CI runs the internal and public journeys in their own lanes with those
settings. The full suite passes in the default configuration. The full
suite isn't meant to run under the internal configuration, because most
fixtures use relays that an internal build hides.

Automated full-app run on an iPhone 17 Pro simulator at the current
head:
- Public build, upgraded in place over a signed-in install: home loads,
a channel opens and a message sends.
- Internal build: a fresh install shows only Sign in. With a saved
organization community, the community menu has no Switch community, and
Settings → Sign out → confirm returns to Sign in.

Real single sign-on can't run in the simulator.

597a8d1970 feat(mobile): rename Activity and add header filters (#9213)
The UI-only part of #9186 by @klopez4212, split out so it can land
without the Activity sync changes.

- The Inbox page becomes Activity, with header controls instead of
menus: a type menu (All, Threads, Mentions, DMs, Reminders, Drafts), a
sender menu (Anyone, People, Agents) and an Unread toggle. All of them
filter the feed the app already loads.
- Activity and Search get a top edge fade. Bulk mark-as-read and the
"New" divider are gone.
- DM thread replies group with their DM row, so the DMs filter includes
them.

Left out, for a separate sync PR: the Activity history cache,
subscriptions to every joined channel, the refresh coalescer,
thread-follow evidence, Reactions and Solo rows, and the read-state
changes. The Activity provider and read-state writes are unchanged from
main.

One fix on top: the iOS filter labels pass an unscaled font size, since
the native button already applies Dynamic Type. Before, large text was
scaled twice.

### Validation

- Kenny's added tests for the header controls (`tabs_journey`) and
`TopEdgeFade`, adjusted for the removed Reactions option. Added tests
for the DM filter, marking a DM row with replies under two thread roots
read, and sender filtering per event.
- Full mobile suite: see the latest CI run. Locally, 11 push and
notification-toggle tests fail identically on an unchanged checkout.
- Automated simulator run (iPhone 17 Pro, iOS 27) of a build combining
this PR with its sibling split: Home rows measure 44 pt, the bell opens
Activity and shows its dot after a row is marked unread,
type/sender/Unread filters each narrow the feed, a row opens its
conversation, Search results scroll under the fade, and filter labels
fit at the largest text size. Screenshots are in Buzz rather than here
because they show internal test data. Android was covered only by widget
tests.

### Before merge

- [x] Automated simulator run of Activity filters, row taps, read and
unread, and Search, with screenshots.

beec055300 feat(mobile): move Activity to a Home bell and align Home spacing (#9212)
The UI-only part of #9193 by @klopez4212, split out so it can land
without the Activity sync changes.

- Activity moves from a row in the Home list to a bell button in the
Home header, with an unread dot driven by the existing Activity feed and
read state.
- Home filter capsules match native iOS and Android widths, with a
subtle outline on Android when the header collapses.
- Home section spacing is tighter.

Left out: the reconnect rewrite in #9193's last commit (live events
applied in place, no rebuild on reconnect, fatal fallback reads). The
Activity provider is unchanged from main. Channel and Solo rows keep
their bottom padding so they stay at the 44 pt minimum tap height.

### Validation

- Kenny's added tests: `inbox_unread_provider_test` (unread dot) and the
Home page bell and filter width tests.
- Full mobile suite: all pass except 11 push and notification-toggle
tests that fail identically on an unchanged checkout in this
environment.
- Automated simulator run (iPhone 17 Pro, iOS 27) of a build combining
this PR with its sibling split: Home rows measure 44 pt, the bell opens
Activity and shows its dot after a row is marked unread,
type/sender/Unread filters each narrow the feed, a row opens its

a1efbf63bd fix(mobile): delete composer chips as one unit (#9133)
In the mobile composer, Buzz links (channel, message, repo, PR, issue)
and selected agent `@mentions` render as chips, with the source text
kept as invisible characters behind the chip. Backspace right after a
chip removed one of those hidden characters, so the chip turned into a
broken raw URL or partial name with no visible change for most of the
presses.

This PR gives chips one consistent editing model:

- **A link is a chip only once something follows it.** Its pattern runs
to whitespace or the end of the text, so in practice that is any time
the caret isn't at its end. Pasting exactly one link adds a space after
it (unless whitespace already follows), so it becomes a chip straight
away.
- **A link shows its raw URL while the caret is at its end.**
Backspacing the space after a chip, or moving the caret back past it,
reveals the URL for editing, one character at a time. Moving the caret
away turns it back into a chip. A caret at the link's start leaves it a
chip.
- **Agent `@mention` chips stay atomic.** Backspace right after one
removes the whole mention.
- **Chips are atomic for selection and forward delete.** A caret placed
inside a chip moves to its nearer edge, arrow keys step over it, and a
selection that covers part of a chip grows to cover all of it. Forward
delete just before a chip removes the whole chip. Typing, pasting,
deleting or cutting over a selection replaces exactly the (snapped)
selection.

The controller records each chip's source range while it builds the
spans, so only what is actually drawn as a chip behaves as a unit. Text
in code spans and IME compositions are never rewritten. Undo restores
the previous text: edits at the end of a revealed link are plain text
edits, so undo no longer looks like a backspace into a chip.

Human `@mentions` aren't chips today and are unchanged.

After this change, in the simulator: a link becomes a chip once a space
follows it, backspace reveals the raw URL, the next backspace removes
one character, and the arrow keys reveal the link and turn it back into
a chip.

### Validation

- Added tests: the composer permalink-chip test now covers the boundary
space and reveal (soft and hardware backspace, arrow keys), caret and
selection snapping, forward delete, paste adding a space, IME
composition, and undo after typing at the end of a link or after
completing a link. The agent-chip test covers whole-mention backspace,
selection snapping over a mention and a mention in a code span. Breaking
each rule (reveal, snapping, paste space, whole-chip delete, widening
only inside one chip) fails a test.
- Focused existing validation: the full mobile suite (`just mobile-check
mobile-test`) passes.
- Automated app run: iPhone 17 Pro simulator, iOS 27, debug build of
this branch, in a private test channel. Typed a Buzz channel link and a
space (chip), backspaced twice (raw URL, then one character removed),
retyped the character and space (chip again), then moved the caret left
past the space (raw URL) and right again (chip). Nothing was sent. The
run covered the composer only; the change touches nothing outside it.

fd0ec10505 perf(mobile): rank search channels once per query (#9136)
Search re-ranked every channel on each live channel event, even while it
sat covered in the back stack, and could move a result while you were
reaching for it. On an iPhone 12 mini in a large community, each re-rank
cost 4 to 20 ms at about 2.4 channel events per second: 454 ms of 2,575
ms UI CPU in a 25 s scroll of a big channel with search behind it, and
343 ms in the 15 s after a resume.

Channel results are now ranked when the query runs and when the set of
channels changes: the first load and a directory install (including one
another caller started). Live channel events no longer reorder shown
results; they only update the shown rows' content (membership badge,
member count, name) in place. The next query ranks the current list.

### Accepted gap

A channel joined, left or renamed while results are shown updates its
row but keeps its position until the next query.

### Validation

- Added test: `live channel events never reorder shown results` adds a
channel and checks it is ranked in, moves it to the top of the list
through activity and checks the shown rows don't move, lets a live event
land between another caller's directory status turning loaded and its
install and checks the open channel shows, then joins that open channel
and checks its Open badge goes without the row moving. It fails when
activity re-ranks again, when a change to the channel set is not ranked,
and when shown rows keep stale content.
- Search suite and full mobile suite pass except the known
notification/push failures that also fail on main. Analyze clean.
- Automated simulator run of this branch (debug build, Builderlab
community): searched "studio", channel and people results listed, opened
a channel result, went back with the results still shown.
- Device numbers are from a wired Profile build of main 120d75d976
(pre-change); the change removes the call path, so there's no
post-change device capture.

1a30e51689 mobile: start new agents on the server-recommended model (#9151)
## Summary

Builderlab's model catalog can now recommend a model and thinking effort
for new agents (`recommended_selection` on
`/v3/beekeeper/get-model-catalog`). The mobile create-agent screen now
starts on that recommendation, so the default can change on the server
without an app release.

New agents start on the first of these that applies:

1. The model an agent link suggests, when the catalog offers it
(unchanged).
2. The server's recommended model and effort.
3. The first Sonnet model at medium effort, as added in #9034. Used
while a deployment sends no recommendation.
4. Blank.

A setup resumed after a failure still keeps its saved choice. A
recommendation that isn't in the returned catalog, or that is malformed,
is ignored. Existing agents' saved models are never changed.

The server only sends a recommendation when the deployment's catalog
config sets `recommended_selection`. Until then, the app keeps falling
back to Sonnet.

## Testing

- Unit tests cover the recommendation beating the Sonnet fallback, a
draft model beating the recommendation, and recommendations that should
be ignored (unsupported effort, unknown model, missing effort,
malformed, absent).
- A new widget test checks that the form opens on the recommended model
and effort instead of Sonnet.
- `just mobile-check` and the full mobile suite (`flutter test
--dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example`) pass locally.

133c883b8c fix(mobile): confirm before starting a Huddle from the header (#9155)
Tapping the headphones button in a channel header used to start a Huddle
straight away, which turned on the microphone and posted "Huddle
started" to the channel. The button is easy to hit by accident. Now,
when no Huddle is running there, the button asks "Start a Huddle?"
first, with Cancel and Start Huddle.

- `showConfirmation` in `shared/widgets/confirmation_dialog.dart` adds a
non-destructive mode to the shared confirm helper.
`showDestructiveConfirmation` now calls it with `destructive: true`, so
existing callers behave the same. On iOS the native UIKit alert reads a
new `destructive` argument and uses `.default` style instead of
`.destructive` when it's false. On other platforms the confirm button
keeps the default `FilledButton` style instead of the error color.
- `_huddleNavigationAction` asks before calling `start`. That covers
both the Material header button and the iOS native navigation action.
Opening or joining a Huddle that's already running stays one tap, and so
do the explicit "Start new" buttons inside the Huddle sheets.

Companion to block/buzz-app#2687, which adds the same confirmation on
desktop. buzz-app#2660 also moves the desktop button away from the
members button, but there's no equivalent move on mobile: the headphones
is the only action in the header.

### Screenshots

Rendered by a scratch widget test from the real `ChannelDetailPage`
(Android/Material path, Inter loaded) at 390×844. The scratch test has
been removed. On iOS, the same confirmation shows as a native UIKit
alert, which isn't captured here because this machine has no iOS
Simulator.

Before: tapping the headphones goes straight into a call.

| ![After,
dark](https://github.com/user-attachments/assets/999c1798-9d91-4b83-b8c2-eb8490da6bf0)
|

### Validation

- The existing journey "community transition cancels and awaits an
in-flight Huddle start" now taps the button and checks that the dialog
appears, that Cancel closes it without publishing anything, and that
tapping again and choosing Start Huddle starts the call. With the
confirm removed, this test fails.
- `channel_member_profile_actions_test` checks that destructive
confirmations still send `destructive: true` to the iOS bridge.
- Full `flutter test`: 4,508 passed. `flutter analyze` and `dart format`
are clean.
- Not yet checked: the iOS native alert on a device or simulator, and a
human trying it.

c39ee507b2 fix(mobile): find verified people who have no profile (#9086)
## What changes

Mobile now finds a person who has a relay-verified profile (NIP-FI, kind
30382) but never published a kind:0 profile. This happens, for example,
when someone skips profile setup. The relay's `POST /profiles/search`
already finds such people by their verified name. Each one comes back as
a kind:30382 head with no kind:0. Mobile kept only kind:0 results, so
these people did not appear.

- `RelaySessionNotifier.searchProfiles` keeps kind:30382 heads from the
endpoint.
- `VerifiedProfilesNotifier.searched` turns a search page into people:
- If the relay authority is not known yet, it first waits for NIP-11
discovery. Otherwise, a search that finished first would drop these
people for that query.
- It checks each head's signature with the directory's off-isolate proof
checker.
- Proven heads go into the verified directory, so the rows show verified
names right away.
- `searchedPeople` (in `verified_profile.dart`) builds one row per
person, in the relay's order:
  - If the person has a kind:0, the newest kind:0 is used, as before.
- If not, it uses the proven head that the authority signed, provided it
parses as an active verified profile.
- These cases add no row:
  - a head signed by another key;
  - a head that names the relay key but has a bad signature;
  - a retraction;
  - a malformed subject.
- **Behavior change for all mobile mentions:** every verified person now
matches in mention ranking by their verified full name and username, as
well as by display name, including people who have a kind:0. The relay's
search matches these same three names. Without this, a person whose
display name is their username (`glilienfeld`, full name "Gabi
Lilienfeld") came back from the relay for "gabi", and then the local
filter dropped them.
- Callers:
  - Mention search, which also serves Add members and New DM.
  - The user rows in global search, through `directoryUsersFromSearch`.

The desktop app has the same fix for Manage members:
https://github.com/block/buzz-app/pull/2554

## Screenshots

These come from the real Add members sheet on an Android emulator. Only
the relay session, verified-profile discovery and the member actions are
faked. The names are made up. Jordan Park has a kind:0. jrivera has only
a verified profile, with the full name "Jordan Rivera". The search is
"jordan". The row shows the verified display name, which here is the
same as the username.

| Search finds jrivera | After tapping + on jrivera |
| --- | --- |
| <img width="300" alt="jrivera is found next to Jordan Park"
src="https://github.com/user-attachments/assets/d93b77b1-1bc7-4d09-afc1-f359616a192a"

src="https://github.com/user-attachments/assets/ce6c7a71-b098-434e-8b0e-ed0de8d1a5a2"
/> |

## Tests

- `add_members_sheet_names_test.dart`: a journey in which Gabi has
`display_name` = `glilienfeld` and `full_name` = "Gabi Lilienfeld", and
NIP-11 discovery is slow.
  - While discovery is pending, typing "gabi" shows nothing yet.
  - When discovery finishes, Gabi appears with no further keystroke.
- A head from another key does not appear, and neither does a head that
names the relay key but has a bad signature.
  - **Add member** adds Gabi's key.
- I removed each fix in turn: the full-name alias, the signature proof,
and the wait for discovery. The journey fails each time, for the
expected reason.
- `verified_profile_test.dart`: a table of `searchedPeople` cases.
  - A kind:0 wins over a head, and the newest kind:0 counts.
- These find nobody: another signer, a retraction, an uppercase subject,
a non-profile kind, and any head when the authority is unknown.
- `relay_session_test.dart` and `channel_management_provider_test.dart`:
rows for the kept heads and the directory row.
- `flutter analyze` is clean, and the full `flutter test` passes on
6efef79cc: 4,462 tests.

**Note:** mobile on `main` does not compile at e558f15fa.
`account_identity_store.dart` calls the removed `_keys`. That fix is
https://github.com/block/buzz/pull/9085. The local runs above had that
one-line fix applied but not committed. Until it lands, mobile CI on
this PR will fail.

## Not covered

- **Search during a reconnect:** discovery starts only when the relay
session is connected. If an HTTP search succeeds while the session is
reconnecting, that search leaves these people out.
- **Discovery failure:** if NIP-11 discovery fails, the search also
leaves these people out.
- In both cases the mention cache keeps that partial page for the query,
and the next search tries discovery again. People who have a kind:0 show
as before. Showing the left-out people when the authority arrives later
would need the cached results to be rebuilt; that is a possible
follow-up.

4aae6c22aa fix(mobile): delay iOS message actions until a deliberate hold (#9049)
## Summary
Increase the iOS message and reaction hold delay from 200 ms to 500 ms,
giving users more time to start scrolling without opening a menu.
Movement detection and other platforms remain unchanged.

Apple documents a [0.5-second default for
UILongPressGestureRecognizer](https://developer.apple.com/documentation/uikit/uilongpressgesturerecognizer/minimumpressduration).

### Related issue
Fixes #8500.

### Testing
- Regression checks fail with the old timeout and pass with the change:
no recognition at 499 ms, recognition by 501 ms, and scrolling after a
300 ms pause cancels the hold.
- Device testing pending; the local iOS simulator SDK is unavailable.
Before review, verify deliberate holds, slow scroll starts, and reaction
holds on an iPhone.

46cdc52d23 test(mobile): lock in invite-page and bare-host community link entry (#9047)
Both mobile community-link fields (Add community and the
welcome/onboarding "Enter a community link" page) already accept a typed
or pasted `https://<host>/invite/<code>` link and keep the code. They
also read a bare host as `wss://`. This PR adds regression coverage for
both. **It doesn't change any production code.**

Companion: block/buzz-app#2412 fixes the same two inputs in buzz-app's
Join a community.

## What's covered

- **`community_link_input_test.dart`**
- The address loop is now an input → relay table, with two new rows:
`secondary.example` and `relay.example.com:8443` (the port is kept).
- The invite case now uses `https://primary.example/invite/fixture`, and
expects relay `wss://primary.example` with code `fixture`.
- Two new rejected inputs: `ws://secondary.example`, and the invite path
with a trailing slash, which the relay doesn't serve.
- **`onboarding_entry_routes_test.dart`**: before the bare-host step,
the journey pastes the invite link into the Add route's field. It
expects the app-level `InviteJoinSheet` to show host `primary.example`
and code `fixture`.

## Shown to catch a regression

I removed the invite/add-community short-circuit in
`parseCommunityLinkInput`. Both the invite unit case and the new journey
step then failed.

## Not in this PR

Two parser differences are left for a separate decision, along with the
tests that depend on them:
- `buzz://connect?relay=…`: mobile rejects it in the fields and silently
drops it as an OS link, but buzz-app, desktop and the web repo browser's
Connect button all use it.
- An invite-page link with a query string: mobile accepts it and throws
the query away, but buzz-app rejects it.

cec918ae7a perf(mobile): show a static placeholder for posterless videos (#9138)
Video messages without a NIP-71 poster (older events, or uploads where
poster generation failed) used to start a network
`VideoPlayerController` for each bubble, seek to 100 ms and show that
paused frame. Nothing cached the frame, and the decoder was disposed
whenever the bubble left the tree, so every scroll back opened a new
stream and decoded again.

Those bubbles now show the existing static "Video attachment"
placeholder with the play button. Nothing loads until the user taps, and
the full-screen viewer behaves as before. Videos that have a poster are
unchanged.

### Validation

- Full mobile Flutter test suite passes, and `flutter analyze` is clean.
- The change is almost pure deletion: the frame loader, its provider and
test seam, and the tests that covered it are removed.
- Limitation: no simulator run. A cloned golden sim built from this
branch signed in to the internal community, but its channel list never
finished loading, so I couldn't open a channel with a posterless video.

1b9b307176 fix(mobile): renew expired assertions for native media and drop retired-session avatars (#9134)
Follow-up to [#9069 media
auth](https://github.com/block/buzz/pull/9069), which merged at its
approved head. This PR carries the fixes for the last review round on
that PR.

### Changes

- **Native media reads renew an expired assertion** (Carl's [recommended
blocker](https://github.com/block/buzz/pull/9069#discussion_r4485183400)).
Voice notes and posterless video previews hand headers to native code.
They now use `freshNativeMediaHeadersProvider`, which awaits
`HostedRelayAuth.headersForUrl` and so asks for a new assertion once the
cached one has expired. Before, while the socket stayed up they sent
none and the relay refused the read. If the renewal fails, the read
falls back to cached headers and the relay decides. The voice-note
player's `headers` callback is now `FutureOr`. Both the iOS
authenticated download and the Android native load await it, then
recheck their generation, so a cancel during a slow renewal never starts
the stale load.
- **Notification avatars drop a retired organization session** ([review
thread](https://github.com/block/buzz/pull/9069#discussion_r4485125609)).
When an avatar download finishes after the organization session that
issued its assertion was replaced, BuzzPushKit removes the cached
response and refuses the avatar.
- **Test:** cached reads never present a signed-out or replaced
account's assertion ([optional
note](https://github.com/block/buzz/pull/9069#discussion_r4485183412)).

Not changed: native reaction-detail avatars still use the cached
assertion. After it expires they fall back to initials.

### Validation

- Each new test was checked to fail with the code it guards reverted:
- `replacedOrganizationSessionRefusesAvatar` (BuzzPushKit): a session
replaced mid-download must be refused.
- `fresh native media headers renew an expired assertion`: covers
renewal and the fallback when renewal fails.
- `remote voice notes renew an expired relay assertion`: a journey
through `VoiceNoteAttachment`; it fails when the attachment is switched
back to the synchronous provider.
- `Android defers remote auth until playback starts`: now cancels during
a slow renewal and expects no native load.
- `an issued assertion serves cached reads for the relay`: now signs out
and restores a replacement account. It fails without the account check.
- `swift test` (69 tests) passes. The full mobile suite (`just
mobile-install mobile-check mobile-test`) passes with these commits on
main as of [#9069 media auth](https://github.com/block/buzz/pull/9069).
- The automated full-app simulator run from [#9069 media
auth](https://github.com/block/buzz/pull/9069) covers the surrounding
flows. This change is limited to the header source for voice notes and
video previews, and none of the test communities enforce the hosted
assertion, so a simulator run would not show the difference. No
end-to-end run against a relay that enforces the assertion.

97ede701c0 fix(mobile): send hosted relay assertion from native media and tombstone paths (#9069)
Follow-up to https://github.com/block/buzz/pull/9056, from an audit for
other places that miss the hosted relay assertion. Hosted and
organization relays require `Nostr-Federated-Identity` on every
non-exempt HTTP request and WebSocket upgrade. The Dart
`HostedRelayHttpClient` adds it, but anything that downloads or connects
outside that client has to add it itself. The notification service
extension and the iOS emoji picker both missed it, and these places do
too:

- **Voice notes** (`just_audio`, mainly Android) and **video preview
first frames** fetch media natively with only the Blossom
`Authorization` header. Both now use `nativeMediaHeadersProvider` from
https://github.com/block/buzz/pull/9056.
- **Push-lease tombstones**: removing a community, and the durable
revocation outbox, open a one-off relay socket with no headers. A hosted
relay refuses the upgrade, so the lease is never revoked and the outbox
keeps retrying. Both now ask `HostedRelayAuth` for that community's own
assertion, because the community being removed may not be the active
session.
- **Notification avatars** (iOS notification service extension):
relay-hosted sender avatars were fetched with Blossom auth only. The
loader now takes the same `BuzzRelayAssertionIssuer` the resolver uses
for `/query`. Signed requests already refuse redirects.

The iOS Me-chat agent picker also fetched avatars with no headers, but
https://github.com/block/buzz/pull/9079 removed that native screen, so
this PR no longer touches it.

### Validation

- Added tests, each checked to fail when the code it guards is reverted:
- A queued push-lease revocation and a community-removal tombstone both
send `Nostr-Federated-Identity` on the WebSocket upgrade, as background
requests. Runs against a local relay socket that handles NIP-42 auth.
- A notification avatar on an organization relay is downloaded with the
issued assertion (BuzzPushKit).
- Issuing for a second community keeps the first one's cached assertion.
A background request records no failure, never backs up the key, and its
failure never reaches the active community's reconnect waiting on it.
- Background issuance never binds an unbound account to its key,
bypasses the shared assertion cache (each attempt gets a fresh
assertion, and foreground use never inherits one that skipped the key
backup), and its failure is never handed to a foreground caller waiting
on it. When it can't get an assertion it sends none, so a non-enforcing
relay still accepts the tombstone.
- A notification avatar whose organization session is replaced
mid-download is refused and dropped from the cache (BuzzPushKit).
- Voice notes and posterless video previews renew an expired assertion
before the native fetch, and fall back to cached headers if renewal
fails. A voice-note attachment journey binds the production provider.
- Cached reads never present a signed-out or replaced account's
assertion.
- `flutter analyze` is clean. `swift test` passes for the BuzzPushKit
avatar loader tests, and `flutter build ios --simulator --debug`
succeeds.
- Full mobile suite (`just mobile-check` and `just mobile-test`) passes
at 2c84940832.
- Automated full-app run on an iOS simulator (debug build of this PR
before it was rebuilt on main, signed in to the internal Builderlab
community with two more communities saved). Passed: launch and channel
list, image attachments and avatars in a channel, New chat sheet kept
open for about 80 seconds before the agent list was opened (all agent
avatars loaded, so headers are requested per download), dismiss and
reopen, background and resume, switching to a second community (its icon
and avatars loaded), and removing a community. The native New chat sheet
is unreachable in the normal flow on this branch (a new chat opens the
Flutter draft page; the native sheet only opens when resuming an
unfinished chat), so that check ran with a temporary local bypass that
was reverted. Limits: none of these communities requires the hosted
relay assertion in this build, so the run shows the Swift-to-Dart header
bridge, the per-relay cache and the tombstone path cause no regression,
not that the assertion is sent or accepted. No voice note, video preview
or deleted message was reachable. Screenshots are omitted because they
show internal channel content.
- Limitations: no end-to-end run against a hosted relay. Simulator
sign-in to a hosted relay needs SSO, so a hosted-relay run needs a
device build.

6793cbd25b fix(mobile): focus the search field when search opens (#9120)
Opening search from Home now focuses the search field, so the keyboard
comes up right away and you can start typing without tapping the field
first. This applies when `SearchPage` opens as its own route; the
embedded variant is unchanged. Closing with X and reopening works as
before (the previous query is kept and the field is focused again).

### Validation

- Extended the existing open-and-close journey in
`search_page_test.dart`: it now opens search without tapping the field
and asserts the field has focus and the keyboard is shown. The step
fails with the production change reverted.
- Full mobile test suite and checks passed in the pre-push hook.
- Automated run on an iOS 27 simulator (iPhone 17 Pro) signed in to a
real community: opened search from Home (keyboard up, caret in the
field), typed a query and got channel and message results, closed with
X, reopened (keyboard up again). The recording contains internal
community content, so it was shared internally rather than here.
- Human testing waived under the author's standing exception; the
automated simulator run above covers it.

c848b6dcad fix(mobile): offer a new identity beside saved keys on unclaimed accounts (#9107)
## Summary

This fixes a dead end in mobile Builderlab sign-in. A new account
(unbound, with no backups) on a device that already had saved identities
could only pick one of those identities. Any saved key forced the
picker, and creating a key required the device to have none. If the
service then definitively rejected binding the chosen key, the app
showed "Let's try that again" with no way forward: the chosen key stayed
in the account's slot, so every retry and every launch re-sent the same
rejected bind.

For an unclaimed account, the picker now also offers **Create a new
identity**:

- Creation writes only this account's empty identity slot, so every
saved and device key is kept.
- Creation is offered only when every current device key was among the
choices shown, so a new identity never silently passes over a key the
user didn't see.
- Bound accounts, accounts with backups, pairing and pending import
never offer it.

When binding a chosen key is definitively rejected, the blocked screen
offers **Choose a different identity**:

- It appears only for a 400, 404, 409 or 422 from `/verify` in the
current attempt, for the current account and pubkey, and never during
pairing, whose transferred key is the only choice. Evidence from an
earlier attempt is cleared before each bind. A challenge rejection, a
403, a 503 or any other ambiguous failure offers nothing.
- Before releasing the slot, it rechecks the account: still unbound
(`/current` and status), no backups, the same subject, and a slot that
still holds that pubkey without a receipt.
- It releases the slot only when another durable copy of the same key
exists (the device inventory or another account slot), then verifies the
slot is empty. No key is deleted: only the account's pointer to the
rejected choice is cleared. A failed or refused release keeps the slot
and the choice, so it can be retried in place or after a restart.
- After release, the picker runs again and offers the saved keys plus
creation.

The recovery code lives in `hosted_flow_identity_recovery.dart`, a part
of `hosted_flow.dart`, to stay within the mobile file-size limit.

### Related issue

None found.

### Testing

**Physical iPhone, a signed release build of `1fb633d55` installed over
the existing app (keychain and saved identities kept):** a saved
identity was rejected, then Choose a different identity, the picker,
Create a new identity and Join your community. Joining then completed.
This head differs from `1fb633d55` only in the guards for leaving,
pairing and a failed or refused release listed below, which this journey
does not reach, and in no UI code. The status of that phone's original
rejection was not captured, so it is not confirmed to be one of the
rejections above. The 409 case is covered by tests.

**Tests (red on `main`, green here):**

- Identity service and store: creation beside offered keys; refusal for
unseen or partly offered device keys; release when another copy exists;
refusal for a sole copy, a binding, a backup, a receipt, another account
or an unusable recheck; failed delete and retry; a cancelled attempt.
- Onboarding journeys: create beside saved keys; select, rejected bind,
restart, choose a different identity, create and bind; ambiguous 503 and
403 failures; challenge rejection and stale evidence.
- Release boundaries: an account switch at `/current`, at status, or
between the recheck and the delete; cancelling between the recheck and
the delete; leaving the picker before a late creation; an unreadable
device inventory; leaving while a release is in flight; a failed delete
retried in place and after a restart; a release refused because the
inventory is unreadable, then retried in place; a rejected paired key.
Each keeps every key, leaves the new account's slot untouched and leaves
a cancelled flow idle, and a retry converges.
- Mutating the creation guard, the generation check, the binding
recheck, the store's receipt check, the account and cancellation checks
before the delete, or the device-inventory error handling fails a test.

dce37f74d7 fix(mobile): skip the read-state snapshot when nothing needs publishing (#9093)
Every mobile resume re-syncs read state and then schedules a read-state
publish, whether or not anything changed. Each publish starts by
downloading the full read-state snapshot (about 1 MB compressed on a
heavy account) and only then finds nothing to send. Together with the
re-sync's own snapshot, that is two full downloads per resume, and a
third when a publish from before backgrounding retries.

The publish now checks first, using the same packing it would publish,
and returns before the snapshot when nothing is pending and no slot
differs from what was last published. When something did change it
behaves exactly as before, snapshot included.

Today the snapshot fails before downloading on gzip-serving relays, so
this only pays off once [#9089 read-state gzip
fix](https://github.com/block/buzz/pull/9089) lands; without this PR,
[#9089 read-state gzip fix](https://github.com/block/buzz/pull/9089)
roughly doubles resume download on heavy accounts. It has no merge-order
dependency.

### Validation

- Added test: `a publish with nothing new skips the snapshot`. It
publishes a change (one snapshot), publishes again with nothing new (no
snapshot, no event), then publishes another change (snapshot and an
event carrying both marks). It fails without the early return.
- Existing read-state suite passes.
- iPhone 12 mini, Profile build, Home backgrounded 12 s and resumed, all
socket bytes received in the 15 s after resume:

| Build | Download per resume | Snapshot fetches |
| --- | --- | --- |
| main (snapshot broken) | 3.07 MB | 0 completed |
| [#9089 read-state gzip fix](https://github.com/block/buzz/pull/9089) |
6.85 MB | 3 |
| [#9089 read-state gzip fix](https://github.com/block/buzz/pull/9089) +
[#9090 no read-state replay](https://github.com/block/buzz/pull/9090) |
6.08 MB | 3 |
| [#9089 read-state gzip fix](https://github.com/block/buzz/pull/9089) +
[#9090 no read-state replay](https://github.com/block/buzz/pull/9090) +
this | 2.71 MB | 1 |

These are single runs on one account with 28 read-state slots, so treat
the numbers as indicative.

244038b495 mobile: reuse channel message rows that did not change (#9115)
Opening the keyboard in a busy channel janked: the composer's bottom
inset changes on every keyboard animation frame, and each change rebuilt
the message list, which rebuilt every visible message row. On an iPhone
12 mini that came to 8 frames over 16 ms per keyboard open, with 290 to
360 ms spent in build. The same cascade runs on every page rebuild, such
as the dozen or so while a large channel settles after returning to the
app.

Flutter skips a rebuild only when it gets the identical widget object
back, so the message list now keeps each row it built and returns it
while nothing the row is built from has changed. Shared inputs (the
message list, membership, channel names, send animations, the focus
callback, today's date and so on) clear the cache when they change. Each
row also compares its neighbors, thread summary, typing and working
state, and send-animation and handoff flags. Rows still rebuild through
their own provider watches. The composer's focus callback is now stable
so the page's rebuilds don't clear the cache.

### Validation

- Added `a growing composer reuses the message rows on screen`: it types
a four-line message and checks that the visible rows are the same widget
objects. It fails without the cache.
- `flutter analyze` is clean. The full mobile suite passes except the 10
push and notification-toggle tests that fail identically on unchanged
main on this machine.
- iPhone 12 mini, Profile build, a 2,000-member channel, one matched run
each before and after (the after column is an earlier revision of this
change with the same mechanism):

| | Before | After |
| --- | --- | --- |
| Keyboard open, build time | 359 ms, 290 ms | 64 ms, 43 ms |
| Keyboard open, frames over 16 ms | 8, 4 | 1, 0 |
| Return to the app, build time | 953 ms | 881 ms |
| Return to the app, frames over 16 ms | 21 | 18 |

Most of what remains on return comes from rows' own watches (for example
the agent display-name map is a new object on every agent directory
reload), which this change doesn't address.
- Automated app run on the same phone with this exact branch: Home,
opening the large channel, opening the keyboard twice (58 and 69 ms of
build, one frame over 16 ms each), scrolling back through several days
of history, and returning to the app after 12 s in the background. Day
dividers, reply counts, reactions and system rows rendered correctly
throughout. Typing is covered by the widget test rather than the device
run, to avoid drafting in a real channel.

- Simulator QA of this branch (Debug build, a private test channel):
typing a four-line message, sending, scrolling to the top and back, a
reaction, an edit, a thread reply, a delete, sending again, and
backgrounding and returning. Every row rendered and updated correctly,
with no replayed send animations. The jump-to-latest button didn't
respond to synthetic simulator taps before or after resume; it's a
native iOS view this change doesn't touch.

e34acb0ac5 fix(mobile): keep reply counts on screen while a reconnect catches up (#9100)
Every time the app comes back from the background, the "N replies" links
under messages in an open channel vanish and reappear a moment later. On
an iPhone 12 mini in a busy channel this happened on nearly every
resume, since the session drops its socket five seconds into the
background and the channel reconnects.

A reconnect discards the channel window and refetches its newest page.
Until that page lands, thread summaries came only from replies already
loaded, which in a windowed channel is usually none. The discarded
window's summaries now stand, below every fresher source (live
summaries, thread queries, overflow floors), until the replacement
history lands, which then decides, including dropping a summary the
relay no longer reports.

### Validation

- Added `reply counts stay on screen while a reconnect catches up`,
which fails when the retained summaries are left out.
- `flutter analyze` is clean and the full mobile suite passes.
- iPhone 12 mini, Profile build, a 2,000-member channel backgrounded 12
s and resumed (same scenario, one run each). Before: the "6 replies"
link vanished for about a second and the timeline shifted up, then back.
After: the link and the scroll position stay put through the catch-up.
- Automated app run on the same phone with this change: Home, search,
the large channel and its resume after the reconnect grace period.

### Accepted gap

If you had scrolled back past the first page, those older rows still
lose their reply counts once the reconnect catch-up finishes, as they do
on main today. Their counts return when pagination refetches their page
or the channel is reopened.

6b8a72e835 fix(mobile): send hosted relay auth with iOS custom emoji downloads (#9056)
On iOS, custom emoji in the native emoji picker often render as the
sparkle fallback icon instead of the image.

The native picker downloads custom emoji with `URLSession` and asks
Flutter for request headers over the `mediaHeaders` channel call. That
call returned only the media read `Authorization` header. Hosted relays
also require the `Nostr-Federated-Identity` assertion, which the Flutter
image path gets from `HostedRelayHttpClient`, so relay-hosted emoji get
a 401 and the picker falls back to sparkles. Emoji hosted elsewhere
still load, which is why only some are missing.

The `mediaHeaders` bridge now also includes the hosted relay assertion
via a new `HostedRelayAuth.headersForUrl`, scoped to the relay's own
origin like `HostedRelayHttpClient`. The native loader refuses redirects
for requests that carry the assertion, matching the Dart client, so the
token can't be forwarded to another host.

The iOS reactions sheet had the same gap: it passes avatar and custom
emoji URLs to native views with only the `Authorization` header. A new
`nativeMediaHeadersProvider` combines both headers for any native media
consumer, and the reactions sheet uses it.

### Validation

- Added tests: the native picker's `mediaHeaders` call returns the relay
assertion for relay media and no headers for an external emoji URL;
`headersForUrl` returns the assertion only for the relay origin (not
another host, subdomain or port). The reactions sheet passes the
combined headers for avatars and custom emoji, and
`nativeMediaHeadersProvider` merges both headers only for relay URLs.
- Focused existing validation: the emoji picker and organization relay
auth suites pass, and `flutter analyze` is clean. In the full mobile
suite, the only failures are 10 in `notification_toggle_test`,
`push_bootstrap_test` and `push_bridge_test`, and they fail the same way
on `main`.
- Automated full-app simulator run (iPhone 17 Pro, iOS 27, debug build
of this branch with hosted auth enabled, signed in to two hosted
communities through a cloned simulator keychain, driven with AXe).
Covered: launch signed in, channel and DM lists, opening a channel and a
DM, the native emoji picker (its Custom section shows the emoji as an
image, not the sparkle fallback), sending a custom emoji message and
seeing it render, reacting with the custom emoji (shown in the
quick-reaction row and as a reaction pill), opening a thread, switching
communities, avatars and community icons, background and resume, and a
cold relaunch. Result: no crashes or regressions seen. Screenshots are
omitted because they show real account and community names.
- Limitations: this run does not reproduce the original bug. The hosted
community's custom emoji also loaded in a temporary build with the relay
assertion removed from the `mediaHeaders` bridge, so its emoji URL
evidently doesn't need the assertion, and the run doesn't prove the fix.
The reactions detail sheet could not be reached because simulated long
presses on the pill opened the message menu, and inline image
attachments were not exercised. A device build against a community whose
emoji are relay-hosted is still needed to confirm the fix.

e558f15faa Mobile: one New chat screen (#9079)
Mobile had two New chat screens.
[#8884](https://github.com/block/buzz/pull/8884) made the Flutter draft
page (first send creates and names the chat) the New chat screen, but
kept the older create form (a native iOS sheet, with a Flutter bottom
sheet on Android) for one case: resuming a creation that an older build
had saved with a chat name and no first message. Nothing creates that
state anymore, so the old form only appeared for users with an
interrupted creation from before that change.

This removes the old form. Every New chat, including that resume case,
now opens the draft page:

- **New chat**: unchanged.
- **Resuming an interrupted creation**: after the existing Resume /
Discard setup / Later prompt, the draft page shows the saved chat with
its agent and workspace locked and a Retry button, the same choices the
old sheet offered when it locked its fields. A creation saved with a
first message resumes exactly as before. One saved without a message
finishes without one, because a saved creation can't change after its
first relay write.

The iOS editor's chat-only code (`presentChat`, `updateChatAssistants`,
the agent list, and its avatar loader) goes too. The same editor still
handles profile fields, channel details and workspace names. The native
test and CI step that covered only the removed chat form are removed.

### Screenshots

A brand new chat already opened the draft page and is unchanged:

width="300">

### Validation

- Changed tests: `me_page_test` checks that Resume and Discard setup
both open the draft page and that no native sheet is requested.
`solo_creation_tags_test` checks that recovering an interrupted named
creation through the draft page's Retry continues with member setup,
keeps the saved name and agent, and adds no first message.
- Full mobile Flutter suite (4,431 passed) and `flutter analyze`
(clean). iOS debug simulator build succeeds.
- Automated simulator run (iPhone 17 Pro, iOS 27, signed-in account):
New chat opened the draft page, the agent picker selected an agent, and
the first send created the chat, which then appeared under Solo. New
workspace still opened the native editor, enabled Create once named, and
showed the Discard changes prompt on cancel. The recording isn't
attached here because it shows internal account content.
- Resuming an interrupted
pre-[#8884](https://github.com/block/buzz/pull/8884) creation can't be
produced by the current build. For the screenshots above, a
capture-only, uncommitted patch to a `main` build seeded one; the branch
build installed over it resumed it on the draft page. The widget tests
cover finishing it.
- `solo_creation_tags_test` also covers a conflicting pending Solo
organization edit during that Retry: the draft offers the Conflicting
Solo changes dialog, keeps the saved creation, and the next Retry
finishes it.

237d794acb perf(mobile): skip re-decrypting read-state blobs (#8966)
## Summary

Read-state blobs are NIP-44 encrypted, and the app decrypts them with
pure-Dart ChaCha20 and HMAC-SHA256 on the UI isolate. Most of those
decrypts repeat earlier work:

- Every live subscription (each launch, resume and reconnect) replays
all of the account's read-state slots, and `_handleIncomingEvent`
decrypts each one again. The measured account has 27 slots of about 55
KB ciphertext each.
- Before every publish, `_publishOnce` fetches the read-state snapshot
and decrypts it, and decodes our own slots a second time to check
they're readable.
- The relay echoes each publish back, and our own blob is decrypted
again.

`ReadStateCrypto` now keeps a bounded memo from ciphertext to plaintext,
one per conversation key. `decrypt` checks it first, and `encrypt`
records the ciphertext it produced. NIP-44 payloads carry a random nonce
and a MAC, so under one key the same ciphertext always decrypts to the
same plaintext. Failed decrypts aren't cached and still throw every
time.

The memo is least recently used: a hit moves the entry to the newest
end, so our own superseded blobs are evicted before live ones. It holds
at most 8,000,000 code units across keys and values (about 8 MB, about
80 full slots). The first version used oldest-first eviction with a 2M
bound, which saved nothing on the device: the 27 slots total about 2.6M,
and a replay in slot order evicted each entry just before its next use.

## Measurements

iPhone 12 mini, Profile/AOT, Tom's Block community. Each run resumes the
app twice from the home screen and samples UI-isolate CPU for 15 s from
each resume.

| Build | `ReadStateCrypto.decrypt` per resume |
| --- | --- |
| `main` 14037e3 | 73 ms, 78 ms |
| `main` + this PR + [#8965](https://github.com/block/buzz/pull/8965) |
9 ms, 4 ms |

On the older base 3d26ed7 the first version of this PR measured 74/70 ms
before and 73/71 ms after (no gain). An instrumented build showed 27
decrypts per resume with 0 memo hits, all on one `ReadStateCrypto`
instance. With the LRU fix, the same base measured 7/3 ms.

## Testing

- New tests: the same ciphertext twice runs the cipher once. A
ciphertext from `encrypt` runs it zero times. Failed decrypts throw
every time. The bound caps retained size.
- Regression tests for the device finding: replaying 27 full-size slots
twice decrypts 27 times, not 54, and a hit keeps a live entry ahead of
superseded blobs under a small bound. Both fail on the first version's
oldest-first memo.
- Manager-level test: after the first sync, three publishes plus the
echo and snapshot fetches add no decrypts (3 total, instead of 6 with
the memo bypassed).
- `just mobile-check mobile-test` passes (pre-push hook), after merging
current `main`.
- Automated device run in place of manual testing: the build above on
the 12 mini, launched and resumed twice into a signed-in Block
community, loading the channel list and syncing read state (snapshot
fetch and live replay of all 27 slots).

5d44038ea5 mobile: invite new users to create their first agent with a bold card (#9036)
## Summary

New users had no cue that the slot at the bottom of Home is where they
make an agent. A one-time, deliberately loud "Create your first agent"
card now sits above the empty Bestie slot and points at it.

- The card spans the screen above the bottom bar, with agent pictures
(the same ones the empty slot cycles through) scattered around its edges
and the message centered as plain text. It's allowed to cover part of
the chat list.
- It waits three seconds on Home, then pops up from the agent slot with
the popover entrance (a quick fade, rise and scale). Leaving Home
restarts the wait, so it never pops over another screen. With reduced
motion it appears without animation after the same wait.
- Tapping the card starts agent creation. The close button dismisses it
for good, as does a screen reader's dismiss action, activating the slot,
or ending up with a Bestie. Dismissal is remembered per account and
community. Other taps on Home go through to the page and leave the card
up.
- It shows when remote agents are on, the Bestie preference has loaded
with none set, and the account owns no agents yet. The last check keeps
existing users who never picked a Bestie from being told to create their
"first" agent.
- It only shows while Home is the current route, so sheets and pushed
screens hide it and it comes back afterwards if it was never dismissed.

The card is a new `BuzzCallout.card` variant of the reusable
`BuzzCallout` in the mobile design system (the plain tip variant stays
available). It uses the inverse surface in light mode and the raised
dark surface in dark mode (matching toasts), with an arrow, existing
radius, spacing and popover elevation tokens, and stays phone-sized on
wider screens. It grows to fit large text below its close button, and it
has live-region semantics, so screen readers announce it.

## Screenshots

These come from the widget test harness with the real agent pictures, at
small (320), standard (393) and landscape phone sizes, plus a tablet.
The harness can't render the native iOS glass bar, so these use the
Flutter bar; the card is the same on both platforms. Pictures look a
little soft because the harness renders at 1x and scales up. In
landscape and on tablets the card stops at large-phone width so the
pictures don't spread too thin.

## Testing

- Launcher tests cover first show and placement, Home staying tappable
underneath without dismissing, the card tap starting creation, the close
button, slot activation without a touch, screen reader dismiss, a Bestie
appearing, no reshow after dismissal, a separate community getting its
own first run, staying hidden for people with agents or without remote
agents, hiding under a sheet, the three-second wait and entrance,
reduced motion, and leaving Home during the wait (each
mutation-checked).
- Component tests cover the tip beside an edge target (320 and 1024
wide, 3x text) and the card: full width at 320, capped on wide screens,
growing at 3x text so the message stays clear of the close button
(mutation-checked), and the close button staying its own screen reader
control.
- The full mobile suite passes locally with CI's dart-defines, and
pre-push mobile checks passed at e2fdb791c.
- Still needs a device check on a real iPhone with a fresh account.

af54258f19 fix(mobile): streamline identity setup and community selection (#9070)
Selecting a saved community now connects only that destination, and
**Find my communities** remains available through **Switcher → Add
Community**. Failed destinations are named; completing nested Add/Find
opens the selected destination without resuming the outer batch.

Fresh hosted account setup now creates and backs up an identity
automatically through email sign-in, invites, community links and
community creation when the resolver confirms there are no
account-bound, backed-up, saved or device identities. Welcome has one
email sign-in entry. Authenticated import, existing-key recovery and
selection retain their explicit paths; pending import survives restart
and attaching a destination. Backup retry retains the same identity.

Web binding retains explicit identity creation and its browser-return
behavior. Self-hosted setup is separate and explicit. New-key creation
still requires platform sealing support; passive account restoration
never creates, binds or backs up an identity.

**Account tradeoff:** setup cannot discover a key stored only elsewhere
and never associated with this account. Such an account receives a new
backed-up, bound identity automatically. Importing a different old key
afterward fails with a binding mismatch; this flow does not undo that
account binding. There is no separate pre-authentication import button.

Pending import now survives retained community/web-bind link decoding:
internal import metadata is stripped before strict public-link parsing.
Once an identity is saved and resolved, the import request is retired
before binding or backup, so restart resumes the existing key. Passive
restoration also repairs stale import intents written by earlier builds
without creating, binding or backing up a key.

Validation (`f114c0e228`):
- All 30 hosted onboarding journeys pass. Import coverage includes
invite-to-community-link retention, restart before import, failed-backup
restart, successful-backup restart, and an older stale import intent.
- Three isolated production mutations (decode filtering, import
completion persistence, passive stale-intent handling) each fail the
relevant journey; restored control passes. Earlier auto-creation and
nested-selection mutations also failed their relevant journeys.
- Carl reviewed both P2 fixes and the final commit with no blockers.
Carl and Pinky previously cleared the shared setup behavior and Android
parity.
- Wes confirmed Android sign-in and fresh account creation on the
preceding build `be5690c684`. Android/iOS builds and earlier manual
acceptance do not establish native acceptance of the new import/restart
fixes. Installed devices remain on that preceding build.

**Remaining acceptance:** current-head CI and native validation of the
import/restart edge cases. Required publication hooks passed, including
mobile analysis/tests, branch-skew and file-size checks. The existing
iOS 16 sealing limitation remains: it cannot create a fresh hosted
identity. No membership/ownership repair, denial-classification change
or floating sign-in-control fix is included.

ec21753e1b Make mobile New DM and Add members pick recipients like mention autocomplete (#9065)
The mobile New DM picker listed the first 50 relay profiles
alphabetically, mostly identities the viewer doesn't know. It ran its
own debounced directory search with no cache, and its rows disappeared
on every keystroke until the search returned. Mention autocomplete in
the composer already solves the same problem well, so New DM and Add
members now use its implementation. Add members was reusing the same New
DM directory search.

### What changes

- **Same candidates and order as mention autocomplete.** The chooser's
candidate building, ranking, row stability, 200 ms debounced search and
search cache now back both surfaces. New DM is treated like a stream
with no members yet: the viewer's own agents and agents shared with them
appear up front, people are found by name, and agents that couldn't
answer the viewer are left out. Typing a name shows the same people in
the same order as `@name` in a stream.
- **Results stay on screen while a search runs.** A query searched
before shows its people immediately, and a longer query starts from the
shorter query's results. A failed search keeps its rows and adds a retry
row below them.
- **Presentation matches the mention rows.** Rows show the name, and
agents show "agent · managed by …". Npub lines are gone.
- **Sheet chrome.** The title is "New DM", like the menu item that opens
it. Both pickers keep their grouped cards but drop the "People and
agents" and "Selected" section titles and the empty header bands above
them (selected recipients stay in their own card at the top with
checkmarks on iOS, as chips on Android). The native iOS picker now
focuses search once it appears, which iOS used to ignore. In New DM a
pick clears the query, as an inserted mention ends its query.
- **Add members keeps what is specific to it.** Existing members and
members just added are never offered, names are still compared with the
channel roster so a same-name candidate is told apart, the query stays
after a pick so several matches can be added in a row, and agents that
don't answer the viewer can still be added, since a channel can hold
them.

While the WebSocket reconnects, the relay agent directory and its owners
keep their last read in the community instead of going empty, so shared
agents already found stay eligible in both New DM and the composer
chooser.

The debug-only offline preview directory and the old directory listing
and search providers are removed, since no picker reads them any more.

### Validation

Added tests: the New DM widget journey now drives the real mention
search through a fake relay session. It covers the empty-query state,
the debounce, rows kept while a longer query searches, cached results
shown again at once, selection, chips and submit. The layout journey
covers the 50-row cap, and the native-bridge journey covers title, rows
without key detail lines, the selection limit and failure handling. The
full `mobile/test/features/channels` suite passes.

Automated app run (iPhone 17 Pro simulator, iOS 27, debug build, Remote
Agents Pilot community): opened New DM from the menu, confirmed the
keyboard comes up with only the viewer's own agents listed, searched for
people and an agent, selected both and confirmed the query cleared after
each pick. Also exercised the composer mention chooser (same results and
order for the same query) and the shared Add members sheet (plain style,
autofocus, search, query kept after a pick). Captures show real
community members, so they're shared internally rather than here. The DM
was not actually created, to avoid a stray conversation; submit is
covered by the widget tests.

f09956179d fix(mobile): keep the composer focused through iOS inactive spells (#9055)
On iPhone, opening Control Center or the app switcher while the composer
is focused can leave the keyboard up over a collapsed composer. The
orphaned keyboard then stays put while you navigate, for example back
from a thread to its channel, and it clips the composer pill.

### Cause

iOS reports a zero keyboard inset while the app is inactive and restores
the keyboard natively when the app returns. The composer treated any
inset drop as a user dismissal: it collapsed, unfocused and removed its
text field. When the keyboard came back, it was attached to no Flutter
field, so nothing could dismiss it. Flutter's own report of the native
side is
[flutter/flutter#189051](https://github.com/flutter/flutter/issues/189051).

### Change

The composer's keyboard observer ignores metrics while the app is not
resumed. iOS reports `resumed` with the inset still at zero and brings
the keyboard back a few hundred milliseconds later, so when a keyboard
that was up hasn't returned at resume, the composer waits a one-second
grace before treating it as dismissed. Any nonzero inset in that window
cancels the wait. A restored keyboard leaves the composer expanded and
focused; a keyboard that really stayed down still collapses the composer
once the grace passes.

### Validation

- Extended the existing "returns to the compact capsule when the
keyboard drops" widget journey with both inactive cases in the order iOS
reports them: resumed at zero with the keyboard returning about 400 ms
later (composer stays focused), and resumed with the keyboard staying
down (composer collapses after the grace). It fails without the fix and
against the first revision of this PR.
- Full mobile check and test suite pass.
- iOS 27 simulator (iPhone 17 Pro, debug build of the first revision):
focused the composer, typed, switched to Settings and back, opened and
closed Control Center, sent a message, and left the channel. The
composer stayed focused through each interruption, sending kept focus,
and leaving dismissed the keyboard. Limitation: the simulator keeps the
keyboard inset through these interruptions, so it reproduces neither the
original bug nor the resume grace; the on-device inset drop is from the
reporter's screen recording and the Flutter issue.

Human app testing is waived under the mobile testing exception; the
simulator pass above is the automated full-app run.

7b3c2f95f2 fix(mobile): bound notices to loaded message history (#9062)
## Summary

Mobile reads system notices older than its loaded message window, even
though those notices cannot yet appear. Bound notice reads by the oldest
loaded message's timestamp to avoid fetching history outside the loaded
time range.

A short or empty bounded response finishes that time range, rather than
all notice history. Preserve the full boundary second, resume when older
message pages load, and keep notices before the first message available
at the start of history. Enforce the 2,000-notice cap before fetching
reactions. Reuse cached reactions and deletions when older pages reveal
their notices.

For channels with fewer than 500 notices, scrolling back can now require
one bounded notice read per older message page. Previously, one
unbounded read covered the channel.

### Related issue

Related: #8962, which changed how mobile loads and displays membership
notices. No duplicate notice-bound PR found in the open mobile-notice
title search.

### Testing

Mutation checks: removing the production `since` argument or restoring
the old unconditional history-end flag each made all four notice-range
cases fail. Command: `cd mobile && flutter test --no-pub
--dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
test/features/channels/channel_notices_journey_test.dart --name 'notice
ranges'`.

Replacing the captured message cursor with a fabricated maximum ID also
fails the empty-range progress regression. Command: `cd mobile &&
flutter test --no-pub
--dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
test/features/channels/channel_messages_provider_test.dart --name 'an
empty notice range'`.

A read-only prepared-query check on local Postgres 17.10 used a
representative kind-40099 query. It held 22 event-related relation locks
with `force_custom_plan` and 99 with `force_generic_plan`. The generic
plan pruned seven of eight partitions during execution but retained the
broader locks. These results do not establish lock reduction or
throughput improvement under the relay's actual cached-plan workload; a
relay load test remains pending.

Native app scrolling against a live relay and human confirmation remain
pending.

For the device check, run `just mobile-dev` on a host with an iOS
Simulator runtime. Connect to a local test relay and open a channel with
more than 150 messages and interleaved topic notices. Scroll back
through at least three message pages, then to the start. Check that
visible notices remain in order and appear once. Disconnect during a
page read, reconnect, and continue scrolling to check recovery.

99873459e9 Keep sign-in toasts usable at large text sizes (#9057)
At large text sizes, organization sign-in prompts could clip their
message and push recovery actions off-screen. Stack actions below the
message above 1.3× text, use fixed card corners, and skip the Dynamic
Island morph for that layout.

Follow-up to #9050, addressing [Wes’s large-text
blocker](https://github.com/block/buzz/pull/9050#discussion_r4469530660).
Normal-size styling and recovery callbacks are unchanged.

Validation: extended existing sign-in/cancel/error journeys at 1×, 2×
and 3× using Inter on a 320×568 viewport; assert text lies inside the
painted clip and the card stays on-screen. Removing the fix fails all
six enlarged-text cases. Mobile checks and full tests run through the
push hook. Human device testing of this follow-up is pending.

account buttons for denied access with 12 pt side and bottom padding.
The account-switch action uses a dark secondary treatment. Recovery

Validation: `just mobile-install mobile-check mobile-test`; widget

switching at 200% text size, and transient-toast coordination. The
cancel regression was verified to fail with its callback disabled.

Local Flutter previews using production widgets, with synthetic state;
not device captures. Manual test: sign in, cancel, retry, and switch
accounts after denied access; verify each action remains reachable and
the toast clears after successful sign-in.

0dd778f800 mobile: start new agents on Sonnet at medium effort (#9034)
## Summary

The mobile create-agent screen opened with model and thinking effort
blank, so the easiest path was picking from the full catalog, expensive
models included. A new agent now starts on the first Sonnet model the
catalog offers, at medium effort when that model supports it. People can
still change either one.

- An agent link that suggests a model still wins when Builderlab offers
that model.
- A setup resumed after a failure keeps the choice it saved.
- If the catalog has no Sonnet model, both start blank like today. If
the Sonnet model has no medium effort, only effort is left blank.

Builderlab doesn't send a default or pricing, so the app matches on
"sonnet" in the model id rather than pinning a version. That keeps
working when the catalog moves to a newer Sonnet.

## Screenshots

Captured from the widget test harness with a catalog listing Opus first,
then Sonnet. The avatar preview is blank because the test doesn't load
network images.

## Testing

- New unit tests cover the default, missing medium effort, no Sonnet,
draft model wins, and a draft model the catalog lacks.
- A new widget test checks the form opens on Sonnet at medium and only
needs a name before Create.
- Full mobile suite passes locally with the CI dart-defines
(`BUZZ_PUSH_GATEWAY_URL`, `BUZZ_AUTH_DOMAINS`) at 256063f95.

f04fa0904c fix(mobile): close the community switcher when the org relay refuses the key (#9042)
## Summary

Follow-up to #9028 (merged).

#9028 closes the community switcher before content loads when
organization sign-in is needed, but it checks the session status once.
When the session is signed in and the relay then refuses the paired key
(`AccountFailure.denied`, which #9001 now saves on purpose), the Home
banner offers **Retry** and **Use a different account**, yet the
switcher keeps covering it until the 20s "taking longer" timeout.

- `organizationSignInPromptVisible()` in
`shared/hosted/organization_sign_in.dart` is now the single rule for
when the banner has an action. The banner uses it, and so does the
switcher.
- The switcher listens to the sign-in session and relay auth while it
waits for content, and closes as soon as the rule turns true. Listeners
are removed on every exit, including the timeout, and the content wait
stops listening once the prompt wins.
- Relay failures stay scoped to the new community's relay and pubkey, so
a stale failure from the previous community can't close the switcher.
- `checking` no longer closes the switcher early (the banner is hidden
then); a later transition to signed out still does.

### Related issue

Related to #9001, #9009 and #9028. No duplicate PR found.

### Testing

- New widget test: signed in, switch to an organization relay with
content pending, then the relay refuses the key, and the switcher
closes. It fails with #9028's one-shot check.
- `flutter analyze` is clean. The full mobile suite passes except 10
push and notification tests, which fail the same way on plain `main` on
this Mac (local environment; CI covers them).
- Pushed with `--no-verify` because of those 10 local failures.

ba7d7825ea fix(mobile): show organization sign-in after pairing (#9028)
## Summary

Show organization sign-in after pairing. The community chooser closes
before it waits for content when the organization session needs sign-in.
A long press on **Scan a QR code** reveals the pairing-code option.

### Related issue

Related to [#9001](https://github.com/block/buzz/pull/9001) and
[#9009](https://github.com/block/buzz/pull/9009). No duplicate PR found.

### Testing

On an iPhone 17 Pro simulator, paired with the Block relay using a build
that includes both related PRs. The app showed **Sign in** on Home.
Completing sign-in remains to be verified.
