64312fa5be fix(mobile): address #8650 second-pass review (#8691)
Follow-up to #8650. This addresses the items from the [second-pass
review](https://github.com/block/buzz/pull/8650#pullrequestreview-5700660448),
which arrived after #8650 merged.

- **Setting menu semantics.** Options in the shared `BuzzSettingMenu`
(model, reasoning effort, and channel TTL) expose their checked state
again. The trigger is announced as a button with enabled and expanded
state, so a disabled "Reasoning effort" no longer reads as plain text.
The `PopupMenuButton` this menu replaced also provided a named route and
a "Dismiss menu" action. `MenuAnchor` does not provide them, so this PR
does not restore them.
- **Remote listing failures.** "Could not load agents" for a failed
Builderlab listing now appears only in communities that support remote
agents. For example, it no longer appears in a non-hosted community
while signed in.
- **Add agent during a community reload.** No change needed here. #8693
already disables Add while the page has no community.

### Validation

- Added tests: setting-menu checked, button, enabled and expanded
semantics; a failed remote listing stays hidden where remote agents are
off. Both fail without these changes.
- Mobile analysis is clean, and the Agents and shared widget tests pass
locally after rebasing onto #8693.
- Not covered: VoiceOver on a device.

a94ebece0e Revert "fix(mobile): push every message in your own Solo chats (#8615)" (#8690)
Reverts [#8615](https://github.com/block/buzz/pull/8615).

Mobile push for Solo chats returns to mention-only, matching buzz-app,
which alerts on every message only in DMs. This also removes the
lease-size guards #8615 added, since they existed to fit Solo chats into
the lease.

### Validation

- Clean revert of bad9d26142 with no conflicts.
- Mobile lint and the full mobile test suite pass.

4b21a10c4b fix: don't notify workflow owners through their attribution tag (#8694)
A workflow message names its owner in a marked p tag, ["p", owner, "", "owner"], for attribution. #p live, history and push matching, operator listeners, desktop, mobile and the iOS NSE treat that tag as attribution rather than a mention. A workflow that mentions its owner adds a plain p, so the owner is notified only when actually mentioned. NOSTR.md records the #p exception.

050d545264 perf(mobile): skip unchanged message footer layout (#8433)
Rebuilding an unchanged message footer currently schedules another
layout even when its overlap value is identical. Only invalidate footer
layout when that value changes, preserving layout updates for actual
geometry changes.

### Stable release recommendation

Exclude from `mobile-release/conference-2026-10`; defer to the following
release. The regression test demonstrates eliminated redundant layout,
but the effect on navigation latency has not been quantified.

### Validation

The added widget regression checks that unchanged footer rebuilds do not
repeat layout and changed overlap still updates geometry. The
independent footer build passes the full mobile suite, analysis, and
native iOS Simulator build. Channel scrolling, opening an existing
reaction list, and thread navigation were exercised on iOS 26.5
Simulator.

The full local repository gate previously encountered an unrelated,
unchanged desktop subprocess timing test failure; that test passed in
isolation. All PR CI checks pass, including the native iOS suite.

be1ac392e8 perf(mobile): render inbox and search previews as plain text (#8675)
### Summary

Inbox rows and search results show each message as a 2-line preview.
That preview was a capped `MessageContent`, so gpt_markdown parsed and
laid out the whole source (syntax-highlighted code blocks and measured
tables included), even though only two lines are painted. A native trace
on an iPhone 12 mini attributed a 102 ms inbox-open frame mostly to this
work.

Previews now skip Markdown entirely. `messagePreviewSource` takes only
the leading lines a preview can show, and at most the first 4,000
characters of a single long line, so link normalization, mention binding
and emoji lookup never scan the rest of a long message.
`messagePreviewPieces` is then a linear pass over those lines, similar
to desktop's `getMarkdownPreviewText`. It drops block syntax (headings,
quotes, list markers, rules, table dividers, code fences) and unwraps
inline emphasis and `<u>`, honoring backslash escapes and keeping inline
(including multi-backtick) and fenced code as literal text. It also
replaces links with their label. The new `MessagePreview` widget renders
the result as a single `Text.rich` with `maxLines` and an ellipsis.

Tokens keep the look they have in the thread view:
- A bound mention is the same `MessageMentionPill` chip, with the bot
icon for agents. An ambiguous mention stays as text.
- `#channel` tokens and `buzz://channel/...` links are the same channel
token chip.
- A `buzz://message`, repo, PR or issue link that shows its own URL
previews with the thread view's short label, such as `general ·
abcdef01`. Both use the shared `buzzLinkLabel` helper.
- Custom emoji render as inline images. Only shortcodes the message
names are looked up in the palette.
- Media links show as "Image", "Video" or "Audio".

Chips in previews are not tappable, and tapping the row opens the
message. Bold, italic, inline code and link styling are no longer shown
in previews. The timeline and thread view are unchanged, and so is the
profile status line, which still uses `MessageContent`.

This replaces this PR's earlier approach of cutting the Markdown source
before parsing. That approach needed delimiter-balance heuristics, and a
security review found a real case (`**` inside a link label) where the
heuristic misfired.

### Validation

- `preview_text_test.dart` is a table test of the parser: block syntax,
emphasis that must and must not unwrap (`snake_case`, a lone `*`),
inline and fenced code, unpaired backticks, links, tables, the line
limit and the long-line cap. It also covers mentions (bound, ambiguous,
inside emphasis, link labels and code), custom emoji (including adjacent
`🅰️b:`), channel tokens and links, message and repo link labels, and
media. The long-line row also asserts that `messagePreviewSource`
returns a bounded prefix.
- `message_preview_test.dart` checks the widget: no `GptMarkdown`, one
capped and ellipsized paragraph, mention chip, custom emoji image,
channel chip, media label and empty content.
- Existing inbox and search tests updated to find `MessagePreview`,
including the agent-chip test in search.
- `flutter analyze` and the full mobile test suite pass at 8c721ba3a
(with `--dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example`, as
`just mobile-test` runs it).
- Device A/B on an iPhone 12 mini, using Profile builds against the real
inbox on the internal relay. Each run was a cold launch followed by 6
Inbox opens, in the order main, fix, main, fix:

  | | main eda26b942 | this PR 6661d594a |
  |---|---|---|
| First open, worst frame (run 1 / run 2) | 40.4 / 34.9 ms | 22.4 / 23.2
ms |
| First open, build total (run 1 / run 2) | 77.8 / 91.1 ms | 38.5 / 52.3
ms |
  | All opens, median worst frame | 27.2 ms | 23.3 ms |
  | All opens, median build total | 43.4 ms | 26.6 ms |

First open drops about 40% in build time and about 14 ms in worst frame.
On warm opens, build time also drops about 40%, but the worst frame
barely moves, so what remains in those frames is not the preview parse.

## Codex review status

Codex reviewed this PR over four rounds. Every finding about cost or
correctness is fixed, and those threads are resolved. Later rounds
turned up narrower and narrower preview edge cases, so the author
decided to stop iterating on Codex findings. Any Codex thread still
open, or any finding Codex posts after f538853ed, is a deliberately
accepted preview limitation and doesn't block merging. Example: a [code
span that continues across a line
break](https://github.com/block/buzz/pull/8675#discussion_r4415196032)
can preview a mention as a chip. The full message view is unaffected.
Only the one- or two-line inbox and search previews can differ from it.

762adad54f fix(mobile): require lowercase hex in native verification (#8702)
Follows [#8657](https://github.com/block/buzz/pull/8657) with the three
optional notes from Carl's
[review](https://github.com/block/buzz/pull/8657#pullrequestreview-5703482477).

- **Lowercase hex only.** `verifySchnorrHex` now rejects uppercase
pubkey, message and sig hex, and `verifiedNostrEventFromJson` rejects an
uppercase sig, as the pure-Dart `bip340` decoder does and NIP-01
requires. (The `nostr` package already lowercases an event's pubkey when
it parses one.) Before this, a key holder could publish a second,
uppercase encoding of the same signature and it would verify.
`_decodeSecretKey` still accepts either case.
- **Bestie record.** `decodeDefaultAgent` now verifies with
`verifiedNostrEventFromJson`, like the other Solo `me_*` records.
- **Rejection tests.** The "other pubkey" row now recomputes the event
id, so it reaches the native Schnorr check instead of failing on the id.
Every row now asserts its `EventValidationReason`, a new row covers an
uppercase sig, and `verifySchnorrHex` is checked with uppercase pubkey,
message and sig.

## Testing

- Making either lowercase pattern accept uppercase again fails the
tests.
- `just mobile-check mobile-test` passed on this change before it moved
onto main. On main, the crypto and Solo/me tests pass.

fffd8ca957 fix(mobile): recover Solo sync silently instead of showing a retry banner (#8701)
## Problem

The mobile Solo section could display "Live updates stopped. Your saved
chats are still available." with a **Retry live updates** button. Any
failed Solo head refresh raised this banner. That includes the refresh
that runs on app resume before the relay has reconnected, and an 8s
history timeout. In those cases the live subscription itself was still
healthy. A later successful refresh did not clear the banner, so it
stayed up until someone tapped Retry.

## Change

- Remove the banner along with `MeSync.syncClosed` and
`meSyncWarningProvider`. Saved chats stay visible the whole time.
- `meGroupsProvider`: on app resume, an interrupted reader (terminal
CLOSED or a failed read) resubscribes on its own while the relay is
connected. Before the relay reconnects, the existing
rebuild-on-reconnect still owns recovery. A healthy reader keeps doing a
plain head refresh.
- Home's pull-to-refresh (`ChannelsPage` with the Solo sliver) now also
restarts the Solo reader. Before this change, that path refreshed
channels only, so in the shipped layout the banner was the only manual
recovery.
- The no-snapshot `_MeRetry` state and the offline-save warning are
unchanged.

## Validation

- `flutter analyze` is clean.
- The pre-push `mobile-checks` passed.
- The journey step in `offline_save_page_test.dart` closes the
subscription, cycles background and foreground, asserts a new
subscription, and checks that a newer event delivered on it is saved.
Removing the `subscriptionClosed` recovery branch fails it.
- The new `channels_page_test.dart` case drags to refresh with a Solo
sliver and asserts the Solo reader restarts. Removing the invalidation
fails it.
- Not yet exercised in the running app. That is checklist steps 2 and 3.

Reviewed by the Royal Court agents (provider lifecycle, recovery/UX,
independent challenge); the one blocker (Home pull-to-refresh) is fixed
here.

ccfc1490e4 perf(mobile): verify signatures with native libsecp256k1 (#8657)
The app already verifies signatures in a few places: NIP-OA agent
profiles and owner attestations, Solo `me_*` records (agent inventory,
archived agents, assistants, sync), and pairing events. Each used
`nostr.Event.fromJson`'s pure-Dart BIP-340 verify, about 11.2 ms per
event on an iPhone SE (2nd gen, Profile). This routes them through
`verifiedNostrEventFromJson` and `verifySchnorrHex`, which keep the same
checks (timestamp range, canonical id, Schnorr signature) and the same
`nostr` exception types, with the signature check in libsecp256k1 (40
µs). NIP-OA owner authorizations are now signed with `signSchnorrHex`,
which removes the last pure-Dart Schnorr call in `lib`.

Incoming relay events are still not verified; that stays a separate
decision.

A native trace showed pure-Dart Schnorr verify in `me_sync` and `nip_oa`
costs 100-125 ms per foreground. This PR moves exactly those sites.

### Validation

- Added tests: the native verifier accepts a valid event and rejects
tampered content, a wrong signature, a different pubkey, malformed and
short signatures, and a zero timestamp, each also rejected by the
pure-Dart verifier. Hex Schnorr helpers are checked in both directions
against `nostr.Schnorr`.
- Focused existing validation: crypto, NIP-OA, Solo/me, pairing and
agent tests pass. `just mobile-install mobile-check mobile-test` passes
at f90823cd1.
- Device: a Profile build of the full native stack ran on an iPhone 12
mini against the internal relay.

ff284d00d3 mobile: stop typing prune ticks from rebuilding channel pages (#8695)
### Summary

Typing in the mobile composer felt slower than a native iOS text field.
A device trace on an iPhone 12 mini showed the cause: while anyone in
the channel is typing, the whole channel page rebuilds once per second,
including the visible message list.

- `ChannelTypingNotifier._prune()` runs on a 1 s timer and assigned a
new list to `state` on every tick, even when nothing had changed.
- `_ResolvedChannelDetailPage` watched the whole list and only filtered
out the current user afterwards, so every tick rebuilt the page and its
`PositionedList` (12 to 35 ms per frame, 8 to 19 ms for the message list
alone).
- Your own typing indicator echoes back from the relay, so the timer
kept running the whole time you typed.

In a 30-key trace, 33 of the 35 frames over 12 ms were these rebuilds,
1.00 s apart.

### Fix

- `_prune()` publishes only when the visible entries change.
`TypingEntry` now compares by value.
- The channel and thread pages watch `visibleTypingProvider`, a
`VisibleTyping` value that already excludes the current user and applies
the page's scope. Your own echo refreshes its expiry every 3 s, which
used to rebuild the page. Now it doesn't.

Other `channelTypingProvider` consumers are unchanged.

### Related issue

None found.

### Testing

- Provider tests: a typing entry held across five prune ticks notifies
listeners once, and the pages' shared `visibleTypingProvider` is not
notified by the user's own refreshed echo but is by another user.
Breaking either guard fails its test.
- `just mobile-check` and `just mobile-test` pass at 8b8a16845.

- Device trace on an iPhone 12 mini: 30 keys typed into a channel
composer, Profile builds with build tracing on both sides. Control is
6661d594a, which has the same page code as main.

  | | control | this PR (5ff754131) |
  |---|---|---|
| Channel page rebuilds while typing | about 1 per second (44 in 40 s) |
0 |
| Largest UI build per key, median / p90 | 4.9 / 29.3 ms | 1.0 / 1.4 ms
|
  | Keys with a build over 16.7 ms | 9/30 | 0/30 |
| Frames with UI work over 12 ms | 35 (33 page rebuilds) | 1 (a
semantics update from the test driver) |
  | ComposeBar frame, median | 10.2 ms | 3.0 ms |

The test driver turns on accessibility, so semantics runs on every frame
in both traces. About 1 key in 4 still has a slow frame with about 1 ms
of build and 2 ms of raster. A Time Profiler capture put that time in
the driver's accessibility queries on the main thread (52% of
main-thread samples while typing, none before the first automated tap),
so it is a test-harness artifact rather than app work.

- Dictation on an iPhone SE (2nd gen): a 15 s paragraph dictated into a
channel composer, Profile builds with build tracing.

  | | main | this PR (5ff754131) |
  |---|---|---|
| UI frame, median / p99 / max | 0.9 / 10.4 / 26.1 ms | 0.9 / 5.3 / 10.8
ms |
  | Frames over 16.7 ms | 10 | 0 |
| Channel page rebuilds | 26 (once a second) | 6 (composer growth, none
over budget) |

Each dictation update costs about 1 ms. The caret stayed at the end and
nothing flickered on either build.

0cde1fe2f4 Make mobile Agents a full-page owned-agent directory (#8693)
Replace the mobile Agents sheet with a full-page directory of verified
owned agents. Add dedicated creation and avatar pages with
catalog-backed model selection, reuse the profile emoji/photo/camera
controls, and expose Builderbot model settings while labeling desktop
agents “Manage on desktop.” Share one account-scoped model catalog
across editable cards and retries. Choose Bestie from the agent profile
using the shared encrypted main-agent record (text-only action, filled
star once selected), and move confirmed deletion to a top-left trash
control with native iOS glass. Include uploaded avatars in owner
registrations so desktop can display them.

Validation: mobile analysis and all 3,958 hosted-enabled app tests
passed; default-build tests run by the push hook. Earlier iPhone build
installed and iterated with the user; the current iOS build succeeds,
but final changes still need a device pass. Independent review found no
new blockers. Actual camera capture and live Bestie sync remain
unconfirmed; the existing shared `main-agent` wire format and Bestie
terminology are retained.

### Snapshots

Widget-harness captures with test data (not native iOS chrome).

3dbc95c3f6 perf(mobile): compute NIP-44 ECDH with native libsecp256k1 (#8656)
`ecdhSharedSecret`, the input to every NIP-44 conversation key
(preferences, read state, reminders, themes, mutes, stars, sections,
sort, pairing, agent observer), used pointycastle's BigInt point
multiplication. That costs about 5.9 ms per call on an iPhone SE (2nd
gen, Profile) and is variable time in the secret scalar. It now calls
libsecp256k1's constant-time `secp256k1_ecdh` through `ecdhX` from #8654
(39.8 µs on the same device), returning the same raw x-coordinate NIP-44
requires. The decoded secret key bytes are zeroed after the call.

Invalid keys now throw `ArgumentError` instead of pointycastle's errors;
callers already treat any throw as a failed derivation.

### Validation

- Added tests: `ecdh_test.dart` compares the native result with the
previous pointycastle algorithm for 32 random key pairs, checks the
NIP-44 v2 `get_conversation_key` vector (secret 1, peer pubkey of secret
2), and checks rejection of a zero secret, an off-curve public key and
wrong lengths.
- Full mobile analyze and test suite pass after rebasing onto main at
da1190e2c, including the desktop nostr-rs NIP-44 interop vector.
- On a device: an iPhone 12 mini Profile build of the full native stack,
connected to the internal relay.

e922dc08ff Unify mobile onboarding and community entry screens (#8687)
## Summary

Use consistent fullscreen screens for identity setup, community
selection, joining, and Add Community. Restore all memberships and open
the selected community; share the community grid with the switcher.

Add QR-first choices, animated link entry with 12px keyboard clearance,
a two-finger double-tap pairing toggle, and the centered reversing bee
loader. Preserve cancellation, Back, and reduced-motion behavior.

Add intentionally omits community creation and Builderlab sign-in: this
route follows sign-in and the existing-community picker.

### Related issue

Related: #8628 (native profile setup). No duplicate fullscreen
onboarding PR found.

### Testing

- Full standard and hosted-authentication mobile suites, static
analysis, and required push checks passed.
- iPhone preview iterated with Kenny; final simulator walkthrough below
uses synthetic data and does not authenticate or save account changes.
- Independent review completed; regressions cover cancellation during
loading, Add recovery after failed/conflicting memberships, retrying
skipped communities, and explicit picker stages.

Walkthrough recorded before the copy and recovery followups:

8abcf2ea2a fix(mobile): keep read state across reconnects and resume (#8672)
### Context
Every app resume and relay reconnect tore down `ReadStateManager` and
built a new one. `ReadStateNotifier.build()` watched the whole
`relaySessionProvider` state, so each status change (disconnected,
connecting, connected) rebuilt the notifier. On an iPhone 12 mini each
resume re-ran the full read-state fetch and decrypt (about 19 to 24
decrypts, 60 to 95 ms).

The rebuild also cleared `_forcedUnreadContexts`, so a message or
channel the user marked unread lost that flag on any connection change.

The watch dates from #422, when the manager was built with
`remoteEnabled` tied to the connection status. #802 made `remoteEnabled`
constant and added the `ref.listen` that calls `reinitializeRemote()` on
connect, but left the watch behind.

### Change
- Watch `relaySessionProvider.notifier` instead of its state. Config,
nsec, community, pubkey, crypto and a replaced session still rebuild.
Status changes don't.
- Reconnects re-sync through the existing listener
(`reinitializeRemote()`: re-fetch, then re-subscribe, preserving the
history and live overlap).
- Re-syncs are serialized. One runs at a time after any pending
`initialize()`, and reconnects that arrive while one waits share it.
Overlapping passes could otherwise each install a live subscription and
leak one.
- A connect that lands while the first `initialize()` is running (the
cold-start connect) skips the re-sync when that initialize fetched and
subscribed successfully. Without this, cold start did the read-state
work twice.

### Validation
- Provider journey: disconnected, connecting and reconnecting cause no
refetch, no re-subscribe and no readiness drop, and the forced-unread
flag and read mark survive. Connected runs exactly one refetch and one
live-subscription swap. A second reconnect behaves the same. Account and
community switches still rebuild and clear forced flags.
- Manager tests: a connect during a successful `initialize()` does not
sync again; one during a failed `initialize()` does, and leaves one live
subscription; three reconnects during a running re-sync produce one more
shared pass and one live subscription.
- Falsified: restoring the old watch fails the reconnect journey
(`isReady` false, flag lost). The previous version without serialized
re-syncs fails the overlap test (5 passes instead of 3).
- `just mobile-check` and `just mobile-test` pass.

iPhone 12 mini (Profile builds of base and this branch, real community
over the production relay, instrumented manager lifecycle and
live-subscription counts):

| | base | this branch |
| --- | --- | --- |
| Resume after 3 s, 10 s (x3), 60 s background | 3 new managers and 3
initializes per resume | no new manager, 1 re-sync |
| Live read-state subscriptions after resume | 1 | 1 |
| Channel marked unread, then 10 s / 60 s background | flag lost after
the first resume | still unread after both |
| Read-state work per resume (median) | ~24 decrypts, ~176 ms main
isolate | ~18 decrypts, ~125 ms |
| Unread badges | same bold set | same bold set |

The first device run also found the doubled cold-start sync, fixed
above. A re-check on this head:

8161a7cad0 perf(mobile): derive public keys with native libsecp256k1 (#8655)
Follows #8654.

Deriving an x-only public key from a secret key with
`nostr.Keys(secret).public` costs about 5.6 ms in pure Dart on an iPhone
SE (2nd gen, Profile). The app does it in 10 places, including relay
config, the signed-event relay's `pubkey` getter, push lease checks,
status updates, and the settings identity row's `build` method. This
routes all of them through `derivePublicKeyHex` from #8654, which takes
16.5 µs on the same device.

Behavior is unchanged for valid keys: output is the same lowercase hex.
For a malformed or out-of-range key the thrown type changes from nostr's
`InvalidKeyException` to `ArgumentError`; every affected site either
catches all errors or rethrows its own `FormatException`/`StateError`,
and nothing in `lib` or `test` matches on the old type.

Sites that need a full `nostr.Keys` object (key generation,
`AccountIdentityStore`) are unchanged.

### Validation

- `derivePublicKeyHex` is checked against `nostr.Keys` for 64 random
keys in #8654's `event_signing_test.dart`.
- Full mobile analyze and test suite pass on this branch after rebasing
onto main, including the package's own tests.
- iPhone 12 mini, Profile build of this stack (with #8656 and #8657 on
top): paired to the internal Buzz community through Desktop; relay auth,
identity row, avatar, and channel/DM/inbox loading all worked under the
derived key.

buzz-review-completed (agent review, Codex and security review clean;
device validation above; human app test not applicable under the mobile
testing exception)

770ab7ff82 perf(mobile): decode relay query responses off the UI isolate (#8669)
### Context

Profiling on an iPhone 12 mini (Profile build, real community) showed
`RelaySessionNotifier._postForEvents` producing contiguous main-isolate
busy runs with p90 110 ms and max 124 ms (27 runs of 50 ms or longer).
Stacks were dominated by `jsonDecode` of `response.body`, with
`NostrEvent.fromJson` smaller. The whole HTTP response decode ran on the
UI isolate: gzip inflate (done by `dart:io`), the UTF-8 decode behind
`response.body`, JSON parsing, and event parsing.

### What changes

- Successful `/query` and `/profiles/search` responses (the only two
callers of `_postForEvents`) are now decoded in a single `Isolate.run`
from `response.bodyBytes`: inflate, UTF-8, JSON, validation,
`NostrEvent.fromJson`. The parsed events come back by ownership transfer
(`Isolate.exit`), not a copy.
- Gzip: the query transport now sends `Accept-Encoding: gzip` and sets
`autoUncompress = false`, so compressed bodies reach the isolate still
compressed. Whether bytes are gzip is decided by the gzip magic bytes,
so a transport that already inflated (or an injected test client) still
works. Error bodies are inflated inline (small).
- Unchanged: `FormatException` messages, the malformed-event wrapping,
`RelayException.body`, and the rate-limit gate reading the error body.
- Fencing (Review-Proven Rule 2): the `_disposed` / `_ageRestricted` /
`_contextGeneration` check still runs before the decode and now runs
again after it. If the session retires during the decode, the query
reports `StateError` even when the decode itself failed, matching the
old ordering where a retired session never decoded.

### Design notes

- `Isolate.run` per response instead of a long-lived worker: no
lifecycle or disposal to manage, no idle isolate heap on a small phone,
easy to fake in tests, and the same shape as `parseProfileEventBatch`.
The main-isolate side of a spawn measured at microseconds, so there is
no size threshold; small responses take the same path.
- Event id and signature verification does not happen on these events on
the main isolate today (nothing in the mobile app verifies queried
events; NIP-OA verification in profile parsing is already in an
isolate), so nothing was moved.
- Other HTTP decode sites found and left alone: invite create/join,
hosted join policy, BuilderLab account, media upload response, community
icon lookup, dev push lease NIP-11, archived-agents. These decode small,
rare responses (one small JSON object each), where an isolate adds
complexity without a measurable gain. Media and avatar byte downloads do
no JSON decoding. The mobile app has no `/count` caller.

### Validation

Added tests (`relay_session_test.dart`, through the production
`queryRelay` / `searchProfiles` path with the real isolate decoder):
parsing with non-ASCII content; profile search; gzip success body and
`Accept-Encoding`; gzip error body feeding the rate-limit gate and
`RelayException.body`; malformed JSON; non-list body; non-object
element; malformed event; invalid UTF-8; error status skips decoding;
session disposed, age-restricted, or retired-before-decode while a
decode is outstanding.

The fencing tests are falsifiable: removing the post-decode check fails
the disposed and age-restricted tests; removing the
retired-wins-over-decode-error branch fails its test; removing the
pre-decode check fails the never-decodes test.

`FakeRelay` (test helper) now injects an inline decoder, because
`fakeAsync` cannot deliver isolate results; it calls the same parse
function.

The default transport still honors `http.runWithClient`, which the
hosted journey tests use to fake the network
(`relay_http_query_client_test.dart`; fails without the fix).

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

Host benchmark (AOT executable on an Apple silicon Mac, median of 25,
copy of the parse logic, main-isolate stall measured with a 0.5 ms
heartbeat timer):

| Response | Main-isolate blocked before | after |
| --- | --- | --- |
| 500 events, ~630 KB | 2.4 ms | 0 ms (max gap 0.05 ms) |
| 500 events, ~630 KB gzip | 3.2 ms | 0 ms (max gap 0.19 ms) |
| 500 events with 50 20 KB avatars, ~1.6 MB | 5.1 ms | 0 ms (max gap
0.28 ms) |
| 500 events, ~4.5 MB | 14.0 ms | 0 ms (max gap 0.27 ms) |
| 500 events, ~4.5 MB (827 KB gzip) | 17.4 ms | 0 ms (max gap 0.35 ms) |

Total latency is unchanged within noise (for example 14.5 ms to 14.9
ms). The host is much faster than the 12 mini, so absolute device
savings should be several times larger.

On the iPhone 12 mini (Profile builds of base and this branch, real
community over the production relay, two runs per scenario; main-isolate
stalls measured with a 4 ms heartbeat timer, since the wireless device
tunnel has no VM service):

| Scenario | Main-isolate `_postForEvents` time, base | this branch |
Max stall, base | this branch |
| --- | --- | --- | --- | --- |
| Cold start + 60 s (~16k events, 7.8 MB gzip) | 282 to 295 ms (max 116
ms) | 0.01 ms | 147 to 150 ms | 100 to 102 ms |
| Inbox + search (~7k events) | 122 to 123 ms (max 111 ms) | 0.01 ms |
138 to 142 ms | 97 to 99 ms |
| Open 6 channels (558 events) | 5 to 6 ms | 0.01 ms | 88 ms | 86 to 87
ms |
| Background 10 s + resume (~7k events) | 118 to 124 ms | 0.01 ms | n/a
(suspension) | n/a |

- The production relay serves gzip (about 4.4:1; the largest catch-up
response is 3.15 MB on the wire, 13.9 MB inflated, 7k events). Inside
the isolate that response takes 30 to 47 ms to inflate, 39 to 55 ms for
UTF-8, 65 to 105 ms for `jsonDecode` and 7 to 32 ms for
`NostrEvent.fromJson`.
- Many 16 to 90 ms stalls remain on both builds; they come from other
work (mostly markdown build and layout), not response decoding.
- Home, channels, inbox, search, profile and a thread render the same on
both builds.

a7e65c91da feat(mobile): choose remote agent models and gate agents on Builderlab sign-in (#8650)
Follow-up to [#8626](https://github.com/block/buzz/pull/8626). Mobile
remote-agent creation now matches desktop.

- **Model and reasoning effort:** Create agent has Model and Reasoning
effort menus. Their options come from the remote service's catalog, and
nothing is preselected (same as desktop). The server checks the
selection against the catalog again before registering, and saves it on
the agent.
- **Builderlab gate:** creating a remote agent requires a hosted
community and Builderlab sign-in. The Agents directory, community bots
and the Bestie chooser stay available without it. Signing out closes an
open Create agent sheet; the Agents sheet stays open.
- **Enrollment:** `attest-agent` enrolls the agent in the requested
community, as on desktop, so the separate `add-buzz-subscription` call
is gone.
- **Quieter progress:** spinners replace the progress bars and the
"Working…" label. Status and success text ("is ready", "Remote agent
deleted.", setup steps) is gone, and only failures show text. Refreshing
an already-loaded agent list no longer blanks it.
- **Shared setting menu:** `BuzzSettingMenu` is a bordered setting row
that opens a Material 3 menu spanning the row's width. Opening it
dismisses the keyboard. The channel-TTL setting in Create channel uses
it too.

Agent avatars and QR/link-based creation follow in stacked PRs. Editing
existing agents comes later.

### Validation

- Checked on the staging iOS simulator with a Builderlab account: the
Agents list, the Create sheet, and the model and effort menus (including
with the keyboard open).
- Added tests: catalog-gated model selection (including switching models
clears an unsupported effort), the Builderlab sign-in gate, controller
creation and resume with a model, a failed listing reported instead of
an empty registry, and create sheet busy and failure states (including
the catalog reload after a rejected create).
- The hosted-only agent tests are skipped without Builderlab defines,
which `mobile-test` doesn't pass. They pass locally with the staging
defines (20/20).
- Not covered: Android.

39b8b2b6a6 feat(mobile): unify Messages navigation with Solo and Team filters (#8649)
## Summary

Unify mobile conversations in Messages with All / Solo / Team filters, a
collapsing header, and separate Search, New, and default-agent
shortcuts. Move workspace actions into the community menu and keep
collapsed sections intact across filters.

Align Inbox and list typography, spacing, and muted controls. Preserve
native glass layering through navigation and give every filtered list
enough clearance above the footer. The default-agent shortcut reads the
shared encrypted preference and opens an existing chat immediately. When
unset, it opens Agents; a star action selects the default through a
production signed, self-encrypted preference writer. Save failures
remain visible and retryable.

Android now uses rounded navigation controls and filters, optically
balanced search icons, and expanding New/community menus with leading
Tabler icons matching iOS. Preset avatars retain transparent WebM
animation through an Android WebView renderer, with lifecycle pausing
and poster fallback.

### Related issue

None found in searches for mobile navigation issues and open PRs.

### Testing

- Android follow-up: ARM64 debug build, Dart analysis, and emulator
checks passed for menu placement, selection, icon alignment, search, and
avatar playback/pause/resume. The avatar implementation passed 3,840
Flutter tests and native Android tests before subsequent styling
iterations. Automated tests for the later menu/icon iterations were
skipped at the author’s request; those earlier results do not cover the
final styling changes.

- Mobile formatting/analysis and full test suite (3,838 passed, 23
skipped, plus 4 push-configuration tests); regression journey covers
filtering, collapse retention, and scrolling the last Solo row above the
footer.
- iPhone 18 Pro simulator (Honeycomb): filters, menus, Inbox,
Invite/Back, Switch Community, and default-agent chat/Back exercised.
iOS release build and Pairing Preview install/launch passed during
iteration, preserving the saved profile.
- P1 follow-up: production writer-to-reader widget journey covers
selection, publish failure/retry, and the unset footer opening Agents.
Simulator Agents open/close passes; its saved community has no
selectable agents, so live selection was not verified there.
- Independent agent review completed; its Solo footer-clearance finding
is fixed. The final clearance adjustment is covered by widget tests;
physical-device acceptance of that adjustment and hosted CI remain
pending.

Final Messages layout:

7c165c3718 Smooth profile avatar editor transitions (#8640)
Smooths profile avatar editing with concurrent 200 ms entry/return
transitions, fixed-size circle movement between tabs, and a crossfade to
the dotted placeholder on cancel. New empty avatars open on Emoji, ready
to save.

Review fixes: keep the suggested emoji separate from the Image fallback,
and preserve native editor transparency across appearance changes.
Regression journeys cover empty Image previews, retained Emoji
selection, and light/dark updates.

Validation: focused Flutter journeys pass; restoring the old baseline
fails both fresh-editor regressions. At `bffb83f5e`: full Flutter suite
and push checks passed; all 107 native tests passed on the iOS
simulator. Prior iPhone visual approval covers the transition work;
these review fixes still need a device check.

974495fd4a fix(mobile): resume reconnect replay from the last live point and spread reconnects (#8659)
## Summary

A relay rolling deploy closes every socket with 1012. On reconnect,
mobile replayed each live subscription's **original filter** (startup
`since`, full `limit`) unless that subscription had received an event,
so quiet subscriptions re-read history back to app start every time.
Reconnects used a fixed 1s delay with no jitter. The delay also reset to
1s on every successful connect, so a client bounced from pod to pod
during a deploy kept coming back at the same moment as every other
client.

**This PR makes two changes:**

1. **Resume cursor.** If a subscription reached EOSE on a connection, it
records `liveUntil`: the time of the last frame received from the relay
on that connection, capped at the clock at close. The replay then uses
`since = max(original since, lastSeen − 5s, liveUntil − 960s)`, and
never goes past the filter's `until`.
- **Why 960s:** the relay accepts `created_at` up to ±900s from its
clock (`MAX_TIMESTAMP_DRIFT_SECS` in
`crates/buzz-relay/src/handlers/ingest.rs`). An event stored after the
close can therefore be backdated by that much, and the extra 60s covers
client clock skew.
- **Only relay frames count as liveness.** Close and error paths never
extend `liveUntil`, so a close noticed after the device sleeps doesn't
overstate how long the subscription was live.
- **Ambiguous EOSE is ignored.** If a subscription has a second REQ on
the same socket, that subscription doesn't advance `liveUntil` for the
rest of the socket. A CLOSED ends liveness for the rest of that socket,
because the retry is a second REQ. Subscription IDs are never reused, so
an old EOSE can't mark a re-subscribe as live.
- **No cursor:** a subscription that never reached EOSE keeps its
previous cursor, or replays as before.
2. **Reconnect spreading.**
- After a 1012 or 1001 close, the first attempt waits a uniform random
delay in [0, 10s]. A client already backing off waits the longer of that
delay and its backoff.
   - Ordinary backoff gets symmetric ±25% jitter, capped at 30s.
- The backoff resets only after a connection stays up for 60s, not on
connect. This matches desktop.
- Foreground resume and a manual `reconnect()` still reset to the base
delay, as before.

**Simpler?** The pure reconnect math (cursor, jitter, spread, stability)
lives in a new `relay_reconnect_policy.dart` and is table-tested on its
own. `relay_session.dart` was near its 1200-line cap, so its five small
private bookkeeping classes moved verbatim to
`relay_session_subscriptions.dart`. Net concept count is unchanged.

**Identified debt (not changed here):**
- Dart's WebSocket ping/pong isn't visible to the session, so a
long-idle but healthy connection that drops replays back to its last
application frame − 960s. This is still bounded, and much cheaper than
replaying from app start.
- The unread catch-up in `channels_provider.dart` runs one REQ per
active channel (`since = readAt + 1`, `limit: 1000`) on reconnect and
every 60s.
- A retryable CLOSED is retried with a 30s cap, no jitter and no attempt
limit.
- `lastSeenCreatedAt` advances on stored events received before EOSE. If
a relay returns stored events newest-first and the socket dies before
EOSE, the next replay can skip older stored events.
- The `lastSeen − 5s` term keeps its existing gap for events backdated
after a close.

### Related issue
N/A. This is part of a set of reconnect-load reductions. Companion PRs:
relay read-pool warm (#8651), desktop (#8652), agent harness (#8653).

### Testing
- Mobile gate on a Linux workstation, at the head SHA:
  - `dart format --set-exit-if-changed`: pass.
  - `flutter analyze`: no issues.
  - Gateway recipe tests: pass.
- `flutter test`: 3881 pass, 1 fail.
`push_gateway_origin_validator_test` fails the same way on `main` on
that host, due to a host git-config error.
- New `relay_reconnect_resume_test.dart`:
  - pure table tests for the cursor and the delay
  - a real-socket test that reads the 1012 close code
- journeys through `RelaySessionNotifier`. They check that a close or
error after an hour asleep doesn't extend liveness, that a second REQ or
a delayed EOSE for an unsubscribed ID can't advance the cursor, and that
a backdated event inside the 960s window is still replayed.
- 22 production mutations, each failing the new tests. They cover every
cursor term, the 960s window, the `until` clamp, the liveness cap, the
ambiguous-EOSE guard, CLOSED handling, jitter, the 1012 spread and
floor, the backoff reset, and close-code capture.
- `fake_relay.dart` now draws a fixed jitter midpoint, so existing
journey tests stay deterministic.

bad9d26142 fix(mobile): push every message in your own Solo chats (#8615)
## Summary

Mobile push only covered Solo chats through explicit mentions. Solo
chats are private streams rather than DMs, and the push lease subscribed
channel-wide only to DMs. Agent replies in your own Solo chats therefore
never woke the phone.

The lease now subscribes channel-wide to the viewer's own joined,
unarchived Solo chats, using the same predicate as the Solo tab,
including older unlabelled Solo chats listed in the encrypted Solo
record. Self-authored messages stay excluded through the existing lease
ignores. Muted Solo chats stay out of the lease, like muted channels, so
they push only on mention. The lease waits while the Solo record loads
so an unresolved record never drops legacy Solo chats. If that record
fails with no cached copy, DM and mention updates proceed without the
legacy chats, which the Solo tab cannot list either, and they return
when it recovers. Solo chats created by someone else still push only on
mention, matching how they appear in the channel list.

A lease is bounded by its channel count (750), by the relay's advertised
plaintext and content sizes, and by NIP-44's 65535-byte plaintext
ceiling. DMs always stay, as before. Solo chats fill the remaining room
most recent first, sized with the publisher's own lease encoding, the
exact NIP-44 payload length and the largest endpoint the relay accepts.
Sizes are computed rather than built, so a relay's advertised limits
never drive an allocation. Solo chats beyond the room push only on
mention instead of failing the lease update or publication, and
Notifications settings says how many. A relay too small even for DMs and
mentions fails push setup visibly instead of saving a lease it would
reject. Publication accepts only endpoint grants in the gateway's
JSON-safe alphabet, so the sizing assumption holds.

Thread replies outside DMs still do not push unless they mention you.
That is a separate gap.

### Related issue

None found.

### Validation

- Added test: the desired lease includes joined DMs and the viewer's own
Solo chats, and includes legacy Solo chats from the Solo record, and
excludes archived and muted Solo chats, other people's Solo chats, and
unlabelled private streams. It fails without the fix.
- Added test: the sync provider holds the desired lease while the Solo
record loads, proceeds without legacy chats if the record fails, and
adds them once it arrives. It fails if loading is treated as empty or if
a failure blocks updates.
- Added tests: over the channel count, and over each size limit (relay
plaintext, relay content, NIP-44 plaintext), the lease keeps every DM
and exactly the newest Solo chats, reports the rest as omitted, and is
accepted by `publishBuzzDevPushLease` with a grant at the relay's
endpoint limit, while a max-length grant that JSON would escape is
rejected as not a gateway grant. A relay advertising a 2^50-byte
endpoint limit is sized without allocating. Each row fails if its guard
is removed.
- Added test: a relay whose content or plaintext limit cannot fit even
the lease without Solo chats rejects that lease at publication, and the
provider fails setup instead of saving it. It fails if the guard is
removed.
- Added test: the NIP-44 payload length matches real encryption at every
padding boundary up to 65535 bytes.
- Added test: Notifications settings shows "Older Solo chats notify only
on mention" with the omitted count. It fails without the row.
- Mobile lint and the full mobile test suite pass.
- Not exercised end to end on a device. A signed dev build was installed
on a test iPhone against a personal dev relay, but the phone's dev
identity owns no assistant there, so the device could not create a Solo
chat without exporting its key. This will be validated in dogfood. The
relay matcher already handles channel-wide `#h` leases for DMs, and Solo
messages use the same kind and scoping.

4ff02bf03b perf(mobile): sign events with native libsecp256k1 on iOS and Android (#8654)
Mobile signs every Nostr event (sends, relay AUTH, media auth headers,
preference writes) in pure Dart on the UI isolate. On an iPhone SE (2nd
gen, Profile build) one BIP-340 signature costs about 10.7 ms and
deriving the public key another 5.6 ms, so a burst of signed writes
drops frames.

This adds `mobile/packages/buzz_secp256k1`, a small FFI package that
builds vendored bitcoin-core/libsecp256k1 v0.8.0 (ecdh, extrakeys,
schnorrsig modules) through a Dart build hook, so the same C and the
same Dart API ship on iOS and Android with no platform bridge code. All
13 `nostr.Event.from` signing sites now go through `signNostrEvent`,
which keeps the `nostr` package's event-id serialization and moves only
key derivation and signing to native code. Calls stay synchronous.

The package also exposes `schnorrVerify` and `ecdhX`; follow-up PRs move
verification and the NIP-44 conversation key over. Incoming relay events
are still not verified, unchanged by this PR.

Safety: the signing context is randomized once per isolate, secret keys
and keypairs are wiped from the native scratch buffer after each call,
aux randomness comes from `Random.secure()`, and the static verify
context runs libsecp256k1's self test before first use.

### Validation

- Added tests: BIP-340 official vectors and native-vs-pure-Dart
differential tests in the package; `event_signing_test.dart` signs with
64 random keys and checks pubkey, event id and signature against the
existing `nostr` builder and verifier, plus malformed-key rejection.
- Full mobile analyze and test suite pass locally.
- Builds: iOS release (framework ~1.3 MB) and Android debug APK with the
library for arm64-v8a, armeabi-v7a and x86_64 (~1.2–1.3 MB each).
- On-device (iPhone SE 2nd gen, Profile, median per op): sign 10,736 µs
→ 41 µs, derive pubkey 5,580 µs → 16.5 µs, full signed event 10,744 µs →
65 µs. Event-id JSON and SHA-256 are 23 µs, so they stay in Dart.
- Device, iOS (iPhone SE 2nd gen, Profile): `buzz_secp256k1.framework`
embedded; the signed-in app authenticated to a real community relay,
loaded channels and history, and paged older messages. No native-asset
or secp256k1 errors in the console.
- Device, Android (emulator, debug): APK contains `libbuzz_secp256k1.so`
and loads it. Against a local mock relay that verifies with the
pure-Dart `nostr` package, the app's NIP-42 AUTH, NIP-98 `POST /query`
headers, and kind 20001/30078 events all verified.
- Blossom GET auth, iOS: the dev relay returns 401 for unauthenticated
`/media/` GETs. From inside the running app, the production
`MediaGetAuthService.headersFor()` header for a nonexistent hash got 404
(accepted, file missing), compared with 401 without it. The community
has no relay-hosted image, so none was rendered.

b310fea05b mobile: find DMs opened ahead of the list everywhere (#8646)
## Summary

This follows up [#8638](https://github.com/block/buzz/pull/8638) and
covers the optional review notes from that PR.

- **Shared lookup.** A new `channelByIdProvider` returns the channel
from the list, or the copy remembered from a fast DM open when the list
doesn't have it yet. The mention picker, mention search failure state,
compose bar DM check, thread page, and message unread action all use it.
Before this change, those surfaces only searched the list, so a DM
opened before the list loaded was treated as an unknown channel. For
example, the mention picker skipped directory search and never labeled
anyone "not in DM".
- **Eviction and scope.** Opened-ahead DMs live in a notifier scoped to
one relay and identity, and `channelByIdProvider` watches it. Once the
list includes a remembered DM, its opened copy is dropped. Remembering
also skips a DM the list already has, since the open's background
refresh can list it first. A DM hidden or left later, or one from
another community or identity, is no longer found through a stale copy.
- **Call-site tests.** Search, the profile Message button, and the New
message sheet now assert that they open the DM with `waitForChannelList:
false`.

## Validation

- `just mobile-check` and `just mobile-test` pass.
- The journey test "a DM opened before the channel list loads sends
mentions" now also checks the outside-person picker in a DM that isn't
in the list yet: a failed directory search shows Retry, then the result
appears labeled "not in DM". Mutation checks: reverting the lookup in
`mentionCandidatesProvider`, `mentionSearchFailedProvider`, or the
compose bar fails the test.
- New tests "a DM opened ahead of the list is not found after it is
left" (including the refresh-before-remember order) and "a DM opened
ahead of the list stays in its community" (a mounted lookup across
community and identity switches). Mutation checks: removing the
eviction, the listed check in `rememberOpened`, the relay or identity
watch, or the lookup's reactive watch each fails a test with `Expected:
null, Actual: <Instance of 'Channel'>`.
- Call-site assertions. Mutation check: flipping any of the three call
sites to `waitForChannelList: true` fails its test with `Expected:
[false], Actual: [true]`.
- Simulator (iPhone 17 Pro, local relay): I started a fresh DM with Sim
Tester from the New message sheet. It opened at once, and typing `@Pat`
showed Pat Peer from the directory, labeled "not in DM".

9e18d17a36 fix(mobile): open new DMs without waiting for a full channel reload (#8638)
## Summary

Starting a DM from the mobile **New message** sheet could look broken:
after picking a person and pressing Done, the sheet kept spinning, so it
seemed like the picker could only add people. The DM was being created,
but `openDm` reloaded the whole channel list (memberships, metadata,
hidden DMs, huddles, names, latest messages) before returning. On a
large account or slow connection that can take many seconds.

Interactive opens (New message sheet, Search, profile sheet) now open
the DM from its own metadata and roster, the same targeted read Solo
chat creation uses, and refresh the channel list in the background. The
sidebar still picks up the DM once that refresh lands. When the open
reopens a hidden DM, the fast path also reads the caller's visibility
snapshot in the same round trip and fails visibly if the relay accepted
the open but didn't unhide it, so Done can retry instead of opening a DM
the sidebar keeps hidden. Search and the profile sheet now push the DM
as an ordinary route, as New message already did, so it doesn't sit on a
spinner while Solo groups load. Hidden-DM resurfacing from Activity
keeps the old behavior (wait for the full list), because that reload is
what clears its hidden state and its retry coalescing depends on it.

The fast open also records the DM it read on the channel list notifier,
which falls back to it until the list catches up. Both composers
(channel and thread) look the DM up through it, so a selected mention in
a just-opened DM doesn't wait on, or fail against, the list, and thread
replies there keep their DM recipients.

`findJoinedChannel` now also carries the DM's participant pubkeys so the
opened DM gets its proper title ("Pat Peer", not "DM") before the list
catches up. It also queries metadata and roster separately instead of
under one shared limit, so a lingering pre-backfill metadata revision on
an older DM can't crowd out the roster.

### Related issue

N/A (reported in Buzz #buzz-mobile).

### Validation

- Added tests: `dm_open_latency_test.dart`, a regression test with the
full channel-list load stalled. The interactive open finishes within 2s
with the right channel id, DM flag, membership, and participants. It
publishes exactly one kind 41010, then the background list refresh runs
once the stall clears. The fake serves events like a relay (newest
first, one limit across kinds) and keeps a stale metadata revision
around; the shared-limit read fails it. The test also covers: a DM the
caller can't read fails visibly, a reopen whose unhide snapshot failed
fails visibly, the default (resurfacing) path still waits for the list,
and a community switch mid-read cancels the open.
- Added test (compose bar journey): with the channel list still loading,
a fast-opened DM sends a selected participant mention as a recipient
instead of failing "could not check who is in this channel". It fails if
the composer ignores the opened DM.
- Added test (thread): a thread reply in a DM opened ahead of the list
sends with the DM channel, so it keeps DM recipient semantics. It fails
if the thread page ignores the opened DM. The latency test also checks
the open records the DM before the list has it.
- Mutation checks: the test fails if the background refresh is removed,
if the default path stops waiting, if the interactive path waits, if
participant pubkeys are dropped, or if the still-hidden check is
removed.
- Added tests (Search and profile journeys): with Solo groups still
loading, tapping a person result or the profile's Message button opens
the DM with its composer, not a placement spinner. Each fails if its
call site drops the ordinary placement.
- Full mobile suite: `just mobile-check` clean, 3847 tests passed (23
skipped), plus the unconfigured-push suite.
- iOS simulator (iPhone 17 Pro) against a local relay: New message, pick
Pat Peer, Done. The sheet closed and the DM opened titled "Pat Peer" in
about 1s. Reopening the existing DM took about 0.8s. The DM appeared in
the sidebar after the background refresh. With 400 ms of added one-way
latency (800 ms RTT) through the local proxy, the same flow opened the
DM in 2.5s.
- Re-ran on the simulator at the final head (84444d2): a new DM with a
second user opened in 0.9s, reopening the existing DM opened in 0.8s,
and both appeared in the sidebar. The hidden-DM reopen case couldn't be
run in the simulator because mobile has no hide action, so it is covered
by the regression test only.
- Simulator at ea4fade: reopened the Pat Peer DM, selected a mention of
Pat Peer, and sent it; the message posted with the mention.
- Simulator at
[d7329ae](d7329aecd2):
reopened the Pat Peer DM from New message (about 1s), opened a thread,
selected a mention of Pat Peer, and sent the reply. It posted, and the
relay stored it with Pat as the `p` recipient.
- Simulator at
[1fe2e35](1fe2e35fc1):
searched for Sim Tester and tapped the person result. The DM opened with
its composer in about 1s.
- Limitation: I couldn't reproduce the reporter's account size, so there
is no before/after timing on a real slow account. The stalled-list test
is the before/after evidence for the latency.
- Mobile human-test step: N/A under the mobile testing exception.

5c2ea2e507 feat(mobile): add full-screen profile setup with inline avatar editing (#8628)
Replace the iOS profile setup sheet with a full-screen name → avatar
flow. Require a display name, enable avatar Continue after Done, and let
Skip save the name without an avatar. After a failed save, Not now
continues without saving the draft.

Embed photo, emoji, and animated avatar editing with native Back/Done,
matching 220-point previews, a rounded-notch pencil edit badge, an entry
haptic, equal emoji-preview spacing, and 200 ms transitions that move
the avatar into its editor position without resizing. Apply appearance
changes live across setup and editing while preserving the draft. Keep
the camera exit rail stationary, use a solid shutter, and present photo
positioning full-screen with Back/Done. Preserve the main Flutter view
during presentation and hide underlying controls from VoiceOver while
editing.

Validation: Flutter analysis, 3,796 Flutter tests, and 106 native tests
passed. Built, installed, and launched the isolated iPhone preview;
inspected the native emoji/badge rendering. The local preview entry
point is excluded. Draft pending real login/join → profile-save
verification and owner verification of the updated device flow.

5a8102ee5b fix(mobile): preserve invite onboarding and offer identity setup (#8617)
## Summary

Cold-start iOS invite links could open the welcome screen without
continuing sign-in, and accounts without a stored backup had no explicit
identity setup choice. Forward scene launch URLs to `app_links`, offer
creation for an unbound account with no backups, and offer matching-key
import for an existing binding without a backup. Existing key storage,
binding, backup, and admission checks remain in use.

Discover saved hosted destinations using `known-communities/list` and
remember successfully admitted destinations with
`known-communities/add`. Saved destinations are not membership proof;
normal admission and the existing failed-claim membership reconciliation
remain separate. A failed save preserves the intent and local community
for idempotent retry.

### Related issue

Related to #8599 (QR-first mobile onboarding) and #8601 (invite policy
consent; overlapping setup UI). No exact duplicate found in the open
onboarding PR / identity-backup issue search.

### Validation before the latest main integration

- 48 tests passed across five focused files: `hosted_journeys_test`,
`hosted_communities_test`, `hosted_communities_flow_test`,
`hosted_environment_flow_test`, and `hosted_multi_backup_recovery_test`.
Test defines enable hosted domains and the push gateway.
- Four additional pairing handoff tests passed with hosted domains
enabled after updating their shared HTTP fixture for community saving.
- Targeted Dart analysis: no issues. Required pre-commit and pre-push
hooks passed, including the broader mobile analysis/test lane and
file-size checks.
- Native iOS build passed during iteration. On an isolated iOS
simulator, a terminated app opened from an invite automatically entered
browser login; human recording confirmed login continued into identity
setup and new identity creation.
- Human staging testing on October 27 passed invite entry with an
existing email/password and new identity, community entry, messaging,
cold restart, and recovery on two separate clean iOS simulators. These
results apply to build `ff2138fc325790e0af4d9a64b2ed033fae3a8295`; the
backend backup-upload blocker described previously is no longer blocking
that tested flow.
- Fresh-account signup through an invite is deferred. Physical-camera QR
scanning, native regression/mutation coverage, independent review, and
native retesting after the latest main integration remain outstanding.
- Known limitation: failed-claim membership reconciliation still calls
`communities/joined`; its endpoint/response contract needs alignment
with the supported backend before that fallback is considered ready. The
successful primary recovery path does not prove this fallback.
- No account reset tooling, environment-specific credentials, generated
dependency files, or recording artifacts are included.


### Current review fixes and validation

Head `9902a98d42904a4a7d44a79541d81ceb94d8eac3` addresses the two review
blockers and both small import races:

- Hosted imports explain a linked-account key mismatch; the shared
self-hosted/occupied-device message remains unchanged. The
linked-account journey enters the wrong key through the actual sheet,
checks the visible error and empty storage, then imports the correct
key.
- Closing the import sheet while its operation is pending now waits for
that operation and resumes successful setup. The new-account journey
covers creation and import, including dismissal while awaiting the
status response, binding, backup receipt, and retry.
- An unbound account with newly appeared backups refuses direct import,
preserving recovery's receipt-before-adoption rule. The existing
multiple-backup invariant covers matching and different imported keys.
- The configured route journey uses host labels and its existing fake
account now supports destination saving; the real-account journeys
separately exercise persistence.

53 tests passed across six focused files with CI's
`BUZZ_AUTH_DOMAINS=buzz.xyz,builderlab.xyz,builderlabstaging.xyz` and
push-gateway define. In a separate clone with independent Git
metadata/build output, restoring the old production import paths failed
the three intended regressions; restoring the fixes passed all 43 tests
in that control. Required pre-commit and pre-push hooks passed,
including mobile analysis/tests and file-size checks. Hosted CI and
native retesting of this head are still pending.

The earlier independent review was at `10815e5d9`; these fixes still
need reviewer confirmation. Optional accessibility and import-navigation
refinements are deferred. Fresh signup, authenticated production
add/list and the membership fallback remain open as described above.

### Staging testing and production configuration

Staging selection is build configuration, not a changed production
default. `HostedEnvironment` is unchanged by this PR:
`BUZZ_BUILDERLAB_URL` defaults to `https://app.builderlab.xyz`;
`BUZZ_AUTH_DOMAINS` is empty by default (hosted account features
disabled). Builds that enable production hosted domains receive these
onboarding behavior fixes after merge. This PR does not deploy anything
or redirect production builds to staging.

Check out this PR (`gh pr checkout 8617` in a dedicated `block/buzz`
checkout/worktree), install dependencies per `mobile/README.md`, and
boot a clean iOS simulator. With the repository-pinned Flutter
toolchain:

```sh
. ./bin/activate-hermit
./scripts/mobile-worktree-overrides.sh
cd mobile
flutter run -d <clean-simulator-udid> \
  --dart-define=BUZZ_BUILDERLAB_URL=https://app.builderlabstaging.xyz \
  --dart-define=BUZZ_AUTH_DOMAINS=communities.public.builderlabstaging.xyz \
  --dart-define=BUZZ_DEBUG_PRIVATE_LOGIN=true
```

Private login requests an ephemeral browser session only in debug
builds. Hosted relay assertions remain off by default; this test does
not validate assertion-enabled admission. Generated local Xcode
settings, dependency metadata, credentials, and simulator state are not
included in the PR.

- Invite test: open a valid public-staging invite in the simulator
browser, choose **Accept invite in Buzz**, sign in or sign up, complete
identity setup, enter the community, and send a message.
- Recovery test: preserve that simulator, start another clean simulator
with the same build, choose **or sign in with email**, and sign into the
same account. Verify the recovered public key matches, the saved
community and earlier message return, and a new message sends.
- Fresh signup: repeat invite entry using a new account. This still
needs human verification.

Keep this PR draft while the listed validation gaps remain.

d4a07063c8 feat(mobile): manage Builderlab remote agents (#8626)
Adds Builderlab remote agents to mobile: a member signed in to
Builderlab can list, create and delete their own hosted agents from the
channels header, and active remote agents show as Online.

Everything is gated by `HostedEnvironment.enabled` (the build-time
`BUZZ_AUTH_DOMAINS` define). App Store and internal release builds do
not set it, so they render and fetch nothing new.

### Behavior

- **Agents** button in the channels header (native iOS bar and Material
header) for hosted communities only. It opens a sheet listing the
community's agents; tapping one pushes its profile inside the same
sheet.
- **Create**: for the member's own agents (the NIP-OA owner is the
member, not the community). Registers the agent with Beekeeper, attests
it to the community, saves optional private instructions, subscribes it
to the relay, then publishes the kind 30177 registration with a NIP-OA
owner proof. A failed step resumes with the same agent identity on
retry; instructions stay in secure storage, never in preferences.
- **Delete**: removes the relay registration, confirms it is gone, then
deletes the Beekeeper agent. A partial failure keeps a retry row in the
list.
- **Presence**: an ACTIVE agent with a live kind 30177 registration on
the active relay shows Online in profiles, channel rows, DMs and
mentions, since remote agents wake on messages. Local presence data is
unchanged.
- Sign-in reuses the shared hosted flow. The account's saved Buzz key
must match the server binding; nothing is adopted or rewritten.
- `BuilderlabAccountClient` gains an allowlist for the six Beekeeper
routes desktop already uses.

Not included from the prototype: the separate entrypoint and second
sign-in, test-community creation, staging-only hosts, QR-code agent
links, and the USB proxy.

### Validation

- Added tests: build-time gate, account/key binding before listing,
setup resume with private instructions, deletion contract and retry,
owner-proof verification, status parsing, presented presence requiring a
live registration in the active community and following registration
publish and removal (mutation-checked), account-change clearing, load
retry, recovery of a pending setup whose instructions were lost, a lost
registration response that can only resume with the same idempotency key
(from any community), an HTTP-rejected registration that can be
discarded, deletion of other agents while a setup is unfinished,
rejection of owner proofs whose signed conditions or profile signature
fail, registration publish and removal over a loopback WebSocket relay
for an `http://`-saved community, and widget tests for in-sheet detail
navigation, creation overlay with failure then resume, and delete
confirmation.
- The new tests also run in the CI lane with `BUZZ_AUTH_DOMAINS`
configured, so the enabled path is covered.
- Full mobile format, analyze and test suite pass locally.
- Independent agent review: no gate leak or key-handling issue found;
its robustness findings (discarding a setup that never got a server
identity, clearing registry state on account change, retrying a skipped
load, guarded notifications) are fixed; discard and account change have
added tests.
- Simulator: a `BUZZ_AUTH_DOMAINS` debug build launches to Builderlab
sign-in. The signed-in flow was not re-run on this branch.
- Codex Security Review: an earlier head received a published review,
and its two findings were fixed. On 745ad85 and be2e31b the review hit
its 45-minute timeout and was cancelled without a result, so the final
head has no published security review.
- Human app test: not applicable under the mobile testing exception. The
end-to-end create, mention and delete flow was demonstrated on the
prototype branch against Builderlab; this PR keeps the same Beekeeper
and relay contracts.

f167c4c3e1 fix(push): accept canonical channel UUIDs across versions (#8609)
Starter channels use UUIDv5 IDs, but mobile push accepted only UUIDv4
channel IDs, so building a subscription that included a starter channel
threw locally. After #8608, no non-v4 ID reaches mobile push today:
positive `#h` filters cover joined DMs only, and mutes are limited to
subscribed channels. This PR is therefore a safety net for future
starter-channel subscriptions, and it prepares mobile for a relay that
accepts them.

Mobile now accepts canonical lowercase, hyphenated UUIDs of any version
in subscriptions. It recognizes both the current `uuid-v4-lowercase`
relay descriptor and a future `uuid-lowercase` descriptor. Against a
`uuid-v4-lowercase` relay, mobile checks positive and mute channel
filters before enrollment or publication, keeps the desired filters, and
rechecks relay capabilities every five minutes instead of sending a
lease the relay would reject.

The relay is unchanged. It keeps validating and advertising
`uuid-v4-lowercase`. Installed mobile builds reject any other
`h_grammar`, and they parse the descriptor before renewal, opt-out and
revocation, so changing the advertisement now would leave their leases
active until expiry. The relay validation and advertisement change will
follow in a separate PR once those builds have drained.
`docs/buzz-push.md` records this sequencing.

### Validation
- Regression tests reproduced the UUIDv5 rejection in Dart before the
fix. Added coverage checks positive and mute filters, persisted
subscription round trips, encrypted lease content, malformed IDs,
retained bounds, parsing of both descriptor grammars, and
pre-publication rejection of non-v4 IDs against a `uuid-v4-lowercase`
relay.
- Mobile push tests on the current head: 104 passed, 4 skipped. `flutter
analyze` on the push code and tests is clean.
- Before the split, exercised actual mobile lease construction, NIP44
encryption and NIP42 publication against an isolated local relay. The
relay half of that exercise is no longer part of this PR.
- Relay source is identical to `main`, so the relay serves the same
descriptor that installed builds parse today.

The standing mobile test exception applies. Agent review and
changed-behavior exercise are complete.

b77ad2ed10 fix(mobile): align Solo agent policy and labels with the owner's inventory (#8616)
## Summary

`main` now discovers Solo agents from the owner's kind 30177
managed-agent inventory. This PR aligns two remaining parts of that path
with desktop's agent library.

- **Unsupported policies fail closed.** Desktop parses each agent's
latest 30177 record as `ManagedAgentEventContent` and drops records it
can't parse. Mobile only checked `name`. It now also requires an integer
`parallelism` in `u32` range, a `respond_to` of `owner-only`,
`allowlist` or `anyone`, an allowlist that is absent or a list of
strings, and string-or-null optional text fields. A newer unsupported
record hides the agent instead of falling back to an older one. Records
written by the apps always carry these fields.
- **The owner's name labels the agent in Solo's selection, header and
creation surfaces.** The directory already used the 30177 `name`.
Message authors and the typing indicator still use the agent's profile
name. The existing-chat header, pending-change label, fallback avatar
initials (header, native header action, new-chat row) and the resumed
native creation's saved agent preferred the agent's self-published
kind:0 name. They now use the owner's name first and fall back to the
profile. Profile artwork is unchanged.

### Validation

- Added tests: a table of 11 unsupported policy shapes that must hide
the agent, accepted policy shapes, and journeys where the owner's name
("Owner Name", "Alpha") differs from the cached profile name
("Confusable …"). The journeys cover the new-chat row's title and
initial and the existing-chat header tooltip, initial and pending label.
They also assert the native new-chat payload and picker row, which
already used the inventory name.
- Mutation checks: removing the policy check fails 10 tests; preferring
the profile for the header name, header initial or new-chat initial
fails the matching journey. The saved-agent name on resumed native
creation has no dedicated test.
- The full mobile suite passes (3,806 tests), and `flutter analyze` is
clean.
- The human-testing requirement does not apply under the mobile client
testing exception.

a4e83dfb50 fix(mobile): open message links to public channels the user has not joined (#8518)
🤖
## Summary
- **Problem:** On mobile, tapping a link to a message in a public
channel did nothing if you had not joined that channel. The app showed a
brief "Channel not found in this workspace" notice and dropped the link,
although you are allowed to read that channel.
- **Now:** The app asks the relay for that one channel. If the channel
is public, it opens as a channel you can read but have not joined, the
same as opening it from Browse channels. Private channels and DMs still
open only when you are a member.

## Details
- Before, the link handler looked for the channel only in the app's
loaded channel list. That list holds the channels you joined. It holds
other public channels only after Browse channels has loaded them.
- When the channel is not in that list, the app now reads that channel's
metadata from the relay (kind:39000, the event that names and describes
a channel). The relay returns it only if you may see it. The app then
refuses private channels and DMs, as Browse already does.
- If the lookup fails, the app shows "Could not open the channel". If
the relay returns no channel, it still shows "Channel not found in this
workspace".
- Links are handled in arrival order. While one link is being looked up,
later links wait, including links to channels you already joined. When
the lookup ends, the app handles the next link. A slow relay can
therefore delay later links by up to the lookup timeout (8 s). The app
shows no loading indicator during the wait.
- A link to a channel already in the list opens at once, even while the
app reconnects to the relay. A link that needs the relay lookup waits
until the relay connection is signed in, then opens without a second
tap. If the connection drops during the lookup, the app keeps the link
and tries again after it reconnects.
- During hosted setup the app turns link navigation off. If a lookup
ends during setup, the link stays queued and opens when setup closes. It
does not open a channel over the setup screen.

### Related issue
None found. #8292 covers a different part of message links.

### Testing
- New dispatcher tests cover a public channel you have not joined, a
private channel you have not joined, and a failed lookup. All three fail
on main and pass here.
- Delayed-lookup tests hold the relay response open. They cover
navigation turning off during the lookup (the link opens only after
navigation turns back on; this test fails without the fix), a queued
link behind a slow lookup, and the dispatcher closing during the lookup.
- Reconnect tests start with cached channels and a reconnecting session.
An unlisted-channel link sends no lookup and stays queued, then opens
after the session connects. A listed-channel link opens at once while
reconnecting. A session drop during the lookup keeps the link and
retries it, both when the session returns after the cancelled lookup
ends and before it ends. The three reconnect cases fail on the previous
head.
- `flutter test test/features/channels test/features/onboarding` (1990
tests) and `flutter analyze` pass on the rebased head.
- End-to-end on an Android emulator (API 36) against a local relay.
Alice made a public channel `#launch-notes` and posted in it. In a
private channel `#team`, she posted a link to that message. The phone
user is a member of `#team` but not of `#launch-notes`. The same install
was upgraded in place from a main build to this branch's build.

| Before (main): tap the link | After: tap the same link | After: link
to a private channel you are not in |

ff9eb8f4dc Make mobile onboarding QR-first and synchronize scanner motion (#8599)
Make QR scanning the primary onboarding action, with full-width
contrasting buttons inside the existing gutters. The landing offers
**Scan a QR code** and **or sign in with email**. A two-finger double
tap on the open welcome area reveals **Enter a community link** and
**Use a pairing code**; a screen-reader action provides the same access.
Action buttons remain outside double-tap detection so scanner taps
respond immediately. Pending sign-in keeps its cancellation action.

The Dynamic Island scanner uses 230 ms opening and closing springs.
Welcome content fades and scales with the same progress, camera startup
begins on the first frame, the scanner prompt fades with the camera
reveal, the live preview adds a 230 ms fade when camera startup
completes, and opening gives selection haptics. Native iOS status
indicators request a matching 230 ms fade, returning when dismissal
begins. Reduced motion is respected.

Validation: full mobile suites and analysis run through local checks and
pre-push hooks. The 230 ms iOS Release build was signed, installed, and
launched in the separate Onboarding app on iPhone Air. The owner
reviewed the simplified landing and immediate tap response; the latest
230 ms timing is installed for comparison. The latest 230 ms build,
including the prompt fade, is installed and launched for comparison.
Native status-bar timing has not been independently measured on-device.


Product intent confirmed by Kenny: the supported visible onboarding
choices are email sign-in or QR scanning. Camera permission/startup
failure intentionally does not expose manual pairing or community-link
recovery. Those remain hidden developer options, with no keyboard path
by design.

b14884980e Speed up mobile Solo chat creation and agent discovery (#8547)
## Summary

Solo compose now opens before agent discovery finishes, and chat
creation avoids full channel-list reloads while overlapping independent
reads. Durable retries, ownership checks, and relay confirmation remain
intact.

The agent picker uses the owner's saved inventory, excludes known
archived identities, verifies profiles off the UI thread, and reuses
avatar artwork.

### Related issue

No matching issue found. Related: #8546 adds project selection to the
same compose surface.

### Testing

- Full mobile suite: 3,755 passed, 19 skipped; four additional artifact
tests passed.
- Analysis, formatting, file-size checks, and iOS Release build passed.
- Regression tests fail when the old blocking paths are restored.
- Installed on a physical iPhone with existing profile/community
settings preserved. Owner tested the earlier creation/picker
improvements; final compose timing awaits device feedback. No timing
recording captured.

5996e5dd8b fix(mobile): isolate push setup failures from app rendering (#8610)
Push subscription setup ran synchronously inside the root widget build,
so an invalid subscription could replace the entire app with Flutter's
error surface. Push initialization and the cold-start native
notification read could also prevent the app from rendering.

Keep push work independent of the app subtree, observe asynchronous
persistence failures, and retain the original errors and stack traces.
Setup retries use bounded backoff; Settings shows a failure and offers
manual retry without resetting navigation. Retry preserves a healthy
revocation worker, and community-removal callbacks follow a recovered
worker so lease cleanup continues after setup recovery.

Related: [#8608](https://github.com/block/buzz/pull/8608) fixes the
specific unrelated-mute input that exposed this startup coupling.

### Validation

Added Flutter journeys cover invalid subscriptions, asynchronous storage
failure, dependency initialization failure, retry exhaustion and manual
recovery, navigation preservation, accessible retry actions, and
pending/failed native startup reads with notification-target recovery.
Both original rendering regressions failed before the fix.
Community-removal coverage also verifies cleanup after a worker
initialization failure and after retrying healthy setup; that regression
failed before the worker fix.

The full mobile suite passed (3,782 tests; 19 existing skips), as did
the four unconfigured-build tests and static analysis. The corrected
head also passed the full pre-push mobile checks and tests, plus 42
focused push and community tests. Rendered widget evidence uses mocked
native platform channels; no device APNs delivery test was performed.

Rendered Flutter widget evidence with synthetic data and mocked native
platform views.

### Setup failure
The app remains usable and Settings offers a retry after push
initialization fails.

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

8ceca8ac46 perf(mobile): batch initial channel read-state seeds (#8607)
## Summary

Opening an uncached community seeded each previously unseen channel's
read marker separately. Every seed copied and serialized the full
read-state snapshot, started three preference writes, and notified
listeners. Home now collects those seeds and saves/emits once, using the
existing monotonic marker admission rules.

For a 400-channel fixture with one existing marker, initial seeding
falls from 399 full snapshot saves to one. Existing unread frontiers,
local-only seeds and explicit read publishing keep their behavior. No
transport, cache, relay or unread eligibility changes. This is
independent of #8580 and #8490.

## Validation

- `just mobile-install mobile-check mobile-test`: clean analysis; 3,779
tests passed, 19 skipped, plus four checks for builds without push
configuration.
- Real Home/channel-provider/read-state journey covers 400 channels,
preservation of an existing unread highlight, persisted marks, no seed
publication, and no repeated seed save on refresh. It replaces the
earlier fake-notifier seed test.
- Restoring the old per-channel loop makes the new journey fail at the
single-snapshot assertion.
- Diff and file-size checks pass.
- Merged current main (`209fcd217`) at `d34d29627`; retained both the
cold read-seeding and cached-community landing test registrations. The
production diff is byte-for-byte unchanged from the version reviewed by
the Court at `6a232ed37`. The complete mobile gates above passed again
on the merged tree.

Device latency is unmeasured. The Court source review found no blockers
at `6a232ed37`; app/device testing and human acceptance remain
unconfirmed. To try: open a community without a saved channel list,
confirm its channels load and existing unread highlights remain correct,
then refresh and reopen it. The performance claim here is reduced save
work, not a measured end-to-end speedup.

209fcd2172 fix(mobile): ignore unrelated mutes when building push subscriptions (#8608)
## Summary
Muting a starter channel (#welcome-everyone or #general) could leave the
iOS app on a blank screen after launch.

Starter channels use UUIDv5 IDs. Push subscription setup checked every
synced mute against the lease's UUIDv4 channel grammar and threw
`FormatException: Push subscription channel ID is invalid.` from
`pushSubscriptionSyncProvider` during build, so the first frame never
rendered. Whether you saw a blank screen depended on whether channels
and mutes finished loading before the first frame.

Mutes only feed the lease as ignore filters for subscribed (DM)
channels, and mutes sync across every community and channel type. So the
builder now matches mutes against the subscribed channels before using
them, instead of validating every mute. Subscribed channel IDs are still
validated as before.

### Related issue
None found.

### Testing
- Captured the failure on a dogfood iPhone build from the device system
log, with a stack trace through `buildDesiredBuzzPushSubscriptions` and
the muted ID `fee88e92-da9f-5958-a910-48db3264ad38` (#welcome-everyone).
Unmuting that channel from desktop fixed the device immediately, which
confirms the cause.
- New regression test `ignores mutes outside the push channel grammar`
fails on `main` with the same exception and passes with this change.
- The pre-push `mobile-checks` hook (`just mobile-check && just
mobile-test`) passed on this head.
- Screenshots: not applicable. This changes no UI. It only stops a
startup failure.

ab73cd9fb5 perf(mobile): restore cached channels before community sync (#8580)
## Summary

Returning to a previously visited community shows its saved channel list
immediately, including offline, while membership and unread state
refresh in the background. Initial revalidation failures keep the list
visible and retry every 60 seconds without overlapping background
attempts. After successful history revalidation, ordinary reconnects use
metadata-only refreshes. A reconnect arriving during a background
request queues one follow-up attempt; timer ticks never queue
overlapping work. History deadlines retain the full-revalidation retry
until history succeeds.

Snapshots are disposable, versioned and scoped by canonical relay URL
and signing identity, capped at 2 MB / 2,000 member channels. They
include hidden-DM IDs and prefer fresher in-memory state. Community
removal and identity replacement retire outstanding writes; re-adding
unchanged credentials preserves the current cache and writer. Startup
sweeps orphan snapshots without waiting for disk acknowledgement;
community mutations also sweep orphan snapshots, including data restored
without secure community records. Cache-delete failures do not block
sign-out or strand push revocation; deletion is attempted before
journaling and retried by orphan cleanup. Successfully persisted
unchanged snapshots skip disk writes; failed writes remain retryable.

The cold path reuses fetched membership rosters, overlaps
profile/latest-message requests, shares verified DM profiles with
avatars, and fetches the own profile once per authenticated connection.
Community connection work overlaps the switching animation; avatar
hydration no longer gates landing. Full channel refreshes also
revalidate cached DM participant profiles so relay-side name changes
reach labels and avatars; metadata-only reconnects and background
refreshes reuse admitted profiles.

Me-chat and invite starter recovery use an explicit fresh membership
fetch that propagates errors while leaving the cached list visible.
Cached layout/read preferences permit immediate landing; newer
cross-device preferences may update ordering or badges after reveal.

Integrated with main’s #8490 idle/resume changes: hidden chats detach
live subscriptions, background membership polling stays quiet, and each
resume reconciles once. Chat history follows main’s live-admission-first
ordering to avoid missing messages committed during relay admission;
cached community landing remains immediate.

## Validation

- `just mobile-install mobile-check mobile-test`: clean analysis; 3,778
tests passed, 19 skipped; four checks for builds without push
configuration passed. File-size and diff checks passed.
- Provider/storage journeys cover offline startup, failed initial
revalidation recovering live delivery, bounded retries, lightweight
reconnects, scope isolation, default-port URLs, padded/mismatched stored
credentials, credential replacement, backup-restored orphan data,
removal races, failed platform deletes and failed writes.
- Follow-up regressions cover interrupted native Me-chat lookup, invite
failure propagation, retry after an initial list failure, history
deadlines, queued reconnects, escaped-path keys, unchanged credential
re-adds and non-blocking startup cleanup. Reverting each of the eight
behavior/caller/cleanup-order fixes fails its corresponding regression.
- DM-name regression changes only the relay profile, verifies a full
refresh updates the channel label and shared profile cache, and confirms
ordinary reconnects avoid another profile request. The original
cache-only implementation fails this regression.
- Original signed-in iPhone 18 Pro debug simulator measurements: Buzz's
413 channels went from 6.26–6.30 s to approximately 1.5 s on returning;
all three warmed communities switched in 1.47–1.54 s. Real socket pause
restored the cached list offline and retained it on reconnect. These are
debug simulator observations, not release-device benchmarks.
- Integration with current main also passes the real-session
resume/background/AUTH and live-admission/detach journeys.
- Follow-up failure paths were exercised with deterministic
provider/storage tests and widget journeys; the running simulator was
not modified during this follow-up.

Human acceptance remains pending; this PR stays draft. Try switching
among previously visited communities, opening a channel, restarting and
repeating. First visits and oversized snapshots require network loading.
Cached metadata can be stale until refresh; it lives in ordinary
preferences without additional application-level encryption. The
snapshot contains no message bodies or credentials. Persistent
disk-deletion failures can leave metadata until a later cleanup
succeeds.

d090ac24bb perf(mobile): cut idle and resume sync churn (#8490)
## Summary

Mobile does background work nobody sees, and it waits on round trips it
doesn't need. This PR fixes four things:

- **Chats you've left let go.** A chat with no listener for 30 s drops
its live and typing subscriptions. Coming back shows the cached timeline
right away, then resubscribes and catches up.
- **No requests before AUTH.** The relay rejects any REQ that arrives
before NIP-42 AUTH completes. History requests are now held until the
socket authenticates, and they flush after the rate-limit gate. Live
subscriptions skip their REQ, and the replay on connect sends it.
`auth-required` is terminal for a live subscription, so a pre-AUTH live
REQ could be dropped for good.
- **Resume reconciles the channel list once.** `resumed` is published
before the session hears about it. So the channel list now decides one
microtask later: if the session is reconnecting, the connect does the
reconcile.
- **The 60 s backstop only runs in the foreground on a connected
session.** After an OS suspension, the missed tick fires at unfreeze,
about 450 ms before the app hears `resumed`, while the session still
looks connected. Without this, that tick triggered a second full sync.

Scope note: while the app is in the foreground, the backstop still
re-downloads membership every 60 s. That matches desktop, which
refetches every 60 s while focused. To drop it, mobile would need to
subscribe to the live membership notices (44100/44101), as desktop does.
That would be a follow-up.

### Related issue

N/A. This is follow-up work from the mobile perf dive. None found.

## Before and after

Simulator setup: iPhone 18 Pro simulator, debug build, a local relay
behind a proxy that adds ~120 ms RTT, and a seeded account with 120
channels. I scripted one identical run against each build:
1. Open 5 channels.
2. Visit 20 more channels.
3. Wait 40 s.
4. Stay idle in the foreground for 3 min.
5. Go to the background for 3 min.
6. Resume.

`main` is `ca3be5501`; the branch is `d77c4e86f`. The last amend changed
only test names. Since then, chat history waits for the live EOSE again
(see the note below), so channel open is back to `main`'s order.

| | `main` | this PR |
|---|---|---|
| Live subscriptions after visiting 20 chats | 61 | 11 |
| Resume: membership reads | 2 (244 kB) | 1 (122 kB) |
| Resume: websocket REQs | 36 | 31 |
| Resume: REQs sent before AUTH | 9 | 0 |
| Resume: REQs rejected as `auth-required` | 2 | 0 |
| Idle foreground, 3 min | 3 membership reads, 12 REQs | same |

Notes:
- **Channel open:** an earlier revision requested history without
waiting for EOSE, which cut the median open from 297 ms to 197 ms.
Review showed it can lose a message. The relay registers the live REQ
only after its access checks, so a message committed in between reached
neither the window read nor the subscription. A timestamp overlap only
covers messages signed within it. Keeping that speedup safely would mean
a second window read on every open, so it's left out.
- **Idle foreground is unchanged by design.** See the scope note above.
- **Background traffic:** the simulator suspends the app shortly after
it leaves the foreground, so both builds sent almost nothing during the
3 minutes in the background. The backstop fix shows up at unfreeze
instead, as the missing second membership read.
- **Resume inbound events:** in this one run, events received over the
websocket on resume were 247 kB on `main` and 338 kB on the branch. I
haven't attributed the difference.

## Test

These extend the existing journeys, plus one new journey:

- **`channel_messages_journey_test`:**
- The window read waits for the live REQ's admission, and a message
signed a minute earlier but committed before admission shows up.
- After the listener leaves, the chat keeps following for 29 s and stops
at 31 s.
- Coming back shows the cached rows immediately, then catches up on a
message sent while away.
- **`relay_session_test`:** a stale-connected resume sends nothing
before AUTH. Then exactly one history REQ and one live REQ go out after
AUTH.
- **New `channels_sync_journey_test`:** drives the real lifecycle,
session and channel notifier against `FakeRelay`:
  - A backgrounding just before a backstop tick sends nothing.
  - A resume after the session paused syncs once.
- An OS-suspension resume with AUTH held syncs once, after AUTH, and
sends no REQ before it.
- **`FakeRelay`:** gained `holdReq`, `holdAuth`, `before_id` pagination
and an injectable clock.

Each guard was mutation-checked, and every mutation failed its test:
- live REQ sent before AUTH
- history sent before AUTH
- resume refresh not deferred
- backstop without the lifecycle check
- history read alongside the live REQ
- a 30-day detach delay

Follow-up, not in this PR: a history REQ already in flight on a socket
that gets replaced still waits for its 8 s timeout. Princess Donut found
this in review; it predates this change.

## Validation

- `flutter analyze`: clean
- Full mobile suite at `678617b`: 3,696 passed
- Court review (Princess Donut on the relay session, Mongo on chat
subscriptions, Mordecai on the channel list plus a challenge pass): no
blocking findings. The rate-limit flush ordering came from that review.

**Human test:** Wes ran `da5077d` on the simulator with his real account
and confirmed it works. `460dc35` then fixed a review blocker: a chat
rebuilt while detached stayed detached. A retest of that path is
pending: leave a chat for more than 30 s, background the app for more
than 5 s, resume, then reopen the chat.

Includes an opt-in local demo (`BUZZ_TYPING_PREVIEW=true`) with mixed
human/agent avatars and count controls; it never publishes typing
events.

### Related issue
Follow-up to #8505. No duplicate found in the typing-avatar PR search.

### Testing
- 3,736 mobile tests plus four unconfigured-push tests passed; analysis
and file-size checks passed.
- Installed and iterated on a physical iPhone with the existing
profile/community preserved; owner reviewed the motion and badge sizing.

e8781caa6f fix(mobile): remove Browse channels from channel list (#8539)
## Summary
Remove the “Browse channels” action above the mobile channel list. The
list now starts with its channel sections or empty state. Remove the
unreachable browse sheet and its obsolete tests; keep channel directory
providers and the create-channel/direct-message actions.

### Related issue
No duplicate removal PR found. Related: #6243 introduced mobile channel
browsing.

### Testing
- `just mobile-check mobile-test`: formatting and analysis passed; 3,729
tests passed, 16 skipped, plus all four unconfigured-push tests.
- Release iOS build succeeded. Installed and launched in place on a
physical iPhone Air in Pairing Preview; existing preferences retained
except channel read-state updated after launch.
- Existing quick-action test asserts the browse button is absent.
- `git diff --check` passed.
- Pre-push hooks passed on commit `269df8b3e` (full mobile checks and
tests plus file-size gate). The first attempt timed out in the unrelated
iOS push-gateway validator test; the unchanged-commit retry passed.
- Full repository `just ci` remains in progress through native desktop
checks; not claimed green.

Draft pending owner visual confirmation and review. Screenshots have not
been captured; installation/launch is not visual acceptance.

1a54eec3db fix(mobile): keep token labels visible in authored Markdown links (#7545)
## Summary

On iOS, an authored Markdown link renders as blank when its label is
recognized as a Buzz channel, mention, or custom emoji. For example:

```markdown
[#2959](https://example.com/)
```

The surrounding text remains visible, but the link has no visible label
or tap target.

Buzz's `_ChannelLinkMd`, `_MentionMd`, and `CustomEmojiMd` components
return `WidgetSpan`s. `gpt_markdown` also renders an authored link
through a `WidgetSpan` and reparses its label through the registered
components. Because the Buzz components were allowed to run inside link
labels, the result was a placeholder nested inside another placeholder,
which does not paint on iOS.

This PR adds the same scope restriction used by `gpt_markdown`'s
built-in link component:

```dart
@override
Set<MarkdownScope> get scopes =>
    MarkdownComponent.allScopesExceptLinkLabel;
```

The override is applied to all three widget-based components. Authored
labels such as `[#2959](url)`, `[@Alice](url)`, and `[👋](url)`
therefore remain ordinary link text, while the same tokens outside links
continue rendering as Buzz pills and custom emoji.

The PR also updates the shared test helpers to find `RichText`
subclasses. Since the upgrade to `gpt_markdown` 1.2.1, body paragraphs
can render through `BidiRichText`; `find.byType(RichText)` does not
match that subclass and could allow an absence assertion to pass without
inspecting the message text.

The handling of unknown bare `#tokens` is deliberately unchanged.
Whether those should remain non-interactive pills or become plain text
is a separate product decision.

### Related issue

Fixes #6124.

This supersedes #6135. That PR solves the same issue by maintaining a
custom fork of `gpt_markdown`'s link component; this PR instead uses the
scoped-component API already available in `gpt_markdown` 1.2.1.

### Testing

Focused suites:

```bash
flutter test \
  test/features/channels/message_content_test.dart \
  test/features/channels/message_content_custom_emoji_test.dart
```

Result: 95 tests passed, 0 failed.

Additional checks:

- `just mobile-check` — passed; analyzer reported no issues.
- `just mobile-fmt` — passed; 549 files formatted with 0 changes.
- Six new regression tests cover channel, mention, emoji, plain-link
control, and outside-link behavior.
- Removing the `_ChannelLinkMd` override causes two regression tests to
fail; removing `_MentionMd` or `CustomEmojiMd` causes one test to fail
in each case.
- Three tests in `message_content_test.dart` directly assert that the
nested-placeholder structure is absent. The custom-emoji tests
separately verify literal text and the absence or presence of
`CustomEmojiImage`, depending on whether the shortcode is inside or
outside a link.

The complete local mobile suite reports 15 failures that reproduce
identically on a clean checkout of `main` at `44316ff7`. In [CI for that
same commit](https://github.com/block/buzz/actions/runs/34238736818),
`Clients / Mobile`, `Mobile`, and `Mobile Swift Domain / Mobile Swift`
all passed.

No native-device screenshot is included. The nested-placeholder fix was
verified through the rendered widget structure, but an iOS simulator
build was blocked by the existing `MLImage.framework` arm64-simulator
incompatibility.

0768397092 feat(mobile): show inline human typing and outgoing avatars (#8505)
## Summary

People typing in a mobile channel now appear beside their avatar in an
inline three-dot bubble, using the existing agent typing animation
instead of the separate composer status strip. Human avatars stay round;
agent identities retain their agent shape. Reduced Motion keeps the dots
still, and thread-scoped typing remains inside its thread.

Restore the viewer’s avatar on the right of their own messages in
channel and Me timelines. Grouped messages show the avatar on the final
bubble, with reactions and reply footers aligned to the bubble.

### Related issue

No duplicate found. Related: #3668 tracks observer-backed agent working
status; this PR changes presentation only and does not add observer
lifecycle behavior.

### Testing

- `just mobile-install`; final pre-push `just mobile-check && just
mobile-test` passed (3,728 tests passed, 16 skipped; 4 unconfigured-push
tests passed). Repository file-size gate and commit formatting passed.
- Regression checks fail against the original channel typing and
outgoing-avatar implementation.
- Pixel 10 / Honeycomb Studios: the recording build exercised inline
human/agent typing, avatar shapes, own-message avatars, and message
arrival. That build predates this fresh-main PR; the PR additionally
uses the shared agent identity lookup.
- Before/after widget-rendered previews use generic sample messages. No
recording identity, app-package override, or demo scripts are included.

### Before / after

Rendered from the production channel widgets using generic sample
messages; Reduce Motion enabled for the stills.

| Before | After |
| --- | --- |
|

![After](https://raw.githubusercontent.com/block/buzz/cc8df55d3a8bbccee4205593fbcff6760a7d1143/pr-8505--after.png)
|

### Manual check

Open a channel and have another person type: their round avatar and
animated dots should appear at the bottom of the conversation and
disappear when the message arrives. Send two consecutive messages: your
avatar should appear once beside the final bubble. Repeat with Reduce
Motion and larger text.

Draft pending human testing of this PR snapshot. Do not merge based on
the earlier recording alone.

93114b4279 fix(mobile): lazily lay out new-DM recipients (#8435)
The new-message picker laid out every recipient inside an outer scroll
view. Searching or changing selection could therefore mount the whole
directory in one frame. Use a bounded sliver viewport so offscreen
recipients stay lazy while the search field and selection chips still
scroll above the keyboard.

### Validation

- Current-head CI passed, including all Flutter test shards, Android,
and native/release Swift jobs. Code and security reviews found no
issues. After merging main and retaining both test imports, all 81
channel-page tests and the full mobile check/test suite passed.

- Added a 200-person widget regression: the original mounts all 200
rows; the fix keeps fewer than 30 mounted through open, search,
selection and removal, and can scroll to the final recipient. Covers
no-match and closing too.
- Strengthened the keyboard/chip test to verify the eight-recipient
limit and that removing a chip makes the ninth recipient reachable.
- All 79 channel-page tests passed; the strengthened limit test and
Flutter analysis passed.
- Native iOS simulator build passed. On a separately cloned paired
simulator, verified populated directory/search, eight selected
recipients, limit message, removal, no-match, scrolling to the final
recipient and close without creating a conversation. Debug/AX
instrumentation and a newer Flutter baseline make this functional
validation, not a controlled release-speed benchmark.
- Normal pre-push mobile checks passed, including formatting, analysis
and the full Flutter test suite. Required CI exposed existing formatting
in `message_carousel_preview_cases.dart`; a separate formatter-only
commit corrects it.
- The full local repository gate hit an unrelated Rust failure in
`buzz-acp::signals_cancel_startup_turn_and_pending_stdin_without_hanging`
(exit status `None` rather than `Some(143)`). No Rust code changed. The
gate stopped at unit tests, so later build stages did not run.

### Related issue

No duplicate recipient-layout fix found in the existing issue/PR search.

### Before and after

The synthetic 200-person picker renders identically before and after
(with a reserved keyboard inset). One image represents both; mounted-row
assertions establish the performance mechanism separately.

bf4a163510 fix(mobile): lazily lay out channel member groups (#8437)
Opening a large channel member sheet mounted and laid out every person
in a grouped column. A captured Debug simulator entrance spent 242 ms in
the UI callback, including 223 ms in layout.

Build each person and agent as a lazy sliver row while preserving the
grouped cards, names, statuses, management menus, and activity actions.
Screen-reader row indices continue across both groups. A separate
formatting-only commit fixes an existing carousel-test formatter
discrepancy. No duplicate member-sheet performance PR or issue found.

### Validation

- Added a 200-member widget regression: the original mounts 100 people
initially; the fix mounts fewer than 20 nearby rows and reaches the
final person and agent.
- Added grouping, compact sizing, empty state, member tap identity,
accessible indices, and scrolled member/agent menu checks. Existing
channel-details “See all” navigation test passes.
- Mobile formatting, static analysis, and the full mobile test suite
passed on the committed tree.
- Synthetic before/after rendering is pixel-identical at the same
viewport.
- Populated native iOS 26.5 simulator workflow: open members, scroll
through people and agents to the end, then close. Final installed build
passed this workflow.

Debug, accessibility automation, profiler overhead, different Flutter
versions, and shared-host load limit timing conclusions. This removes
eager offscreen layout; it does not establish a controlled end-to-end
speedup or release-device performance.

### Visual check

Synthetic member sheet; before and after are pixel-identical at this
viewport.

a93f3282cc perf(mobile): retain preference crypto across reconnects (#8442)
Foreground reconnects rebuild preference managers and repeatedly derive
the same NIP-44 keys on the UI isolate. Retain the six crypto objects in
providers scoped to relay configuration and identity while preserving
manager refresh, subscription, and publication behavior. Community
changes, key rotation, and sign-out invalidate the retained objects.

RelayConfig normalizes the signing key once at its shared accessor, so
identity, theme encryption, event signing, and NIP-42 authentication
receive the same value, including when an active configuration key has
surrounding whitespace. The identity-export authorization snapshot uses
the same normalized key for the active-identity check and the outgoing
recovery payload. The branch incorporates main's relay-scoped preference
managers.

### Validation
- Regression exercises six production crypto providers across
reconnects, configuration/key changes, and sign-out. Reintroducing a
session dependency makes it fail.
- Added a loopback WebSocket regression that exercises actual
RelaySocket NIP-42 authentication with a padded key and verifies its
challenge, relay, pubkey and signature. It fails before shared key
normalization.
- Added a connected-theme regression for whitespace-padded keys,
encryption round-trip, and a valid published event signature. It fails
before the normalization fix.
- Added padded-key identity export coverage through authorization, SAS
confirmation, exactly one normalized payload, and successful completion.
Separate relay-change and key-rotation tests verify both fresh and
expired grants fail closed. The padded-key regression failed before the
fix.
- Current head: all 48 focused pairing/crypto/auth tests and mobile
analysis passed. All [CI
checks](https://github.com/block/buzz/actions/runs/39497098787) passed,
including mobile test shards, Android, native Swift tests and release
builds. Codex feedback is addressed; Jude approved this exact head after
independent regression and mutation checks. Fresh [Codex security
review](https://github.com/block/buzz/pull/8442#issuecomment-6300273942)
found no concrete issues.
- Previous head: 122 config/socket/crypto/theme tests, 44 read-state
tests, and all [GitHub CI
checks](https://github.com/block/buzz/actions/runs/39491550425) passed,
including mobile test shards, Android, native Swift tests and release
builds.
- Original implementation: native iOS Debug build and full local
repository checks passed. A paired simulator background/resume capture
had no samples in the targeted crypto constructors or key derivation; an
82 ms UI frame remained. Debug/JIT, profiler overhead and shared-host
activity prevent an overall speedup claim. The later normalization
change is covered by the production-provider regression above.
- Two image decode timing failures occurred in the initial local full
suite; direct baseline/patch runs, the subsequent full repository run,
and the latest full mobile suite passed.

Cold-start credential validation is unchanged: padded persisted keys are
rejected by AuthNotifier before RelayConfig is constructed. The
normalization regressions cover active configurations and identity
export, not broader persisted-key acceptance.

ca35114209 fix(mobile): simplify and refine the quick actions menu (#8491)

Validation: mobile formatting/analysis and full mobile test suite;
mutation check confirms the new journey fails when directory loading is

cdc2b129c0 fix(mobile): resolve DM display labels once per sort (#8488)
Home's DM sort resolves participant identity names again for every
comparator call. This work appeared in a captured 82.163 ms UI frame
after foregrounding the full app (Debug/JIT iOS simulator, shared host).
Resolve each lowercase display label once per sort, retaining the same
label ordering and channel-ID tie-breaker. Sort keys are
invocation-local, so later viewer, profile, owner, participant, and
community changes cannot reuse stale labels.

No matching open mobile sorting PR or issue found.

### Validation

- Added synthetic regression coverage for bounded contextual resolution
and ordering parity across identity/name/channel changes, ties, unnamed
DMs, and empty/singleton lists. The 80-DM fixture performs 80 contextual
resolutions instead of the original comparator’s 982; restoring that
comparator makes the regression fail.
- 133 focused tests passed, including existing Home scrolling/reconnect
widget tests and identity-name tests.
- Mobile static analysis passed; 3,697 tests passed with 16 existing
skips, plus four no-gateway configuration tests.
- No new full-app or hardware capture. The existing trace establishes
repeated synchronous work, not its release-build magnitude or the cause
of every scrolling stall.

5fefec604f fix(mobile): restore channel icons and align chat colors with desktop (#8478)
## Summary
- Restores `#` and lock icons for public and private channels on Home,
with matching loading placeholders.
- Updates the dark-mode navigation colors to the desktop design-system
tokens (read and unread text, section headings).
- Replaces the chat color picker with the seven desktop accents (Gray,
Chartreuse, Flame, Magenta, Iris, Cobalt, Jade). Saved legacy colors map
to the closest one.
- Uses white text in your own bubbles, and black where white falls below
4.5:1 (Chartreuse, dark-mode Gray). Links (underlined), quotes, tables
and code use the same text color.
- Insets code blocks in bubbles evenly, with corners concentric to the
bubble and even inner padding.
- The swipe-to-reply indicator uses the chosen chat color.

## Testing
- `flutter analyze` and `dart format` are clean. The full mobile suite
passes (3,705 tests).
- Installed and checked on a Pixel 10 and an iPhone Air against a real
community.

c9e35f8ac7 fix(mobile): restore Solo chats from channel labels (#8466)
Restore Solo chats and project placement on mobile using `buzz.solo`
labels and creator metadata. Invalidate stale channel details when
identity changes so opening and sending preserve refreshed Solo
identity; shared chats retain ordinary sending. New mobile Solo chats
publish the discovery label, and the personal send guard enforces
ownership even when route hints or legacy placement suggest Solo.

The current desktop producer lives in `block/buzz-app`. [Contract
documentation](0201ca0572/docs/solo-mobile-contract.md)
links its production creation call to relay identity generation and
mobile regression coverage. Public metadata fields are documented.

Validation: clean analysis; 3,542 mobile tests (5 skipped), 4 push
checks, and 280 core unit/doc tests passed. Removing the cache fix
reproduces the send failure. Local push hooks were skipped with owner
approval after an unrelated terminal timeout and disk exhaustion; full
local CI is not green. GitHub CI must validate the pushed commit. The
initial build was installed/launched on iPhone; follow-up native and
live cross-client confirmation remain pending.

The ownership regression supplies a valid owned member recipient and
checks the exact rejection. A New chat UI test captures the real signed
kind-9007 command. Both regressions were mutation-verified: removing the
ownership guard or the production creation label causes the
corresponding test to fail.
