## Summary
- make mobile unread state visible with bold channel names, an animated
Inbox badge, and swipe-to-toggle Inbox rows
- add directional transitions for top-level mobile navigation
- let mobile send while media uploads, with cancellable progress UI
- normalize iOS and Android video uploads, attach poster frames, and
improve native video playback
## Validation
- `just mobile-check`
- `just mobile-test`
- `cargo test -p buzz-media`
- Pixel smoke test
- iPhone smoke test
Desktop background uploads moved to #4522 so the two platforms can be
reviewed independently.

### Summary
Fixes [this
issue](buzz://message?channel=e62570dd-33ad-42c5-b92b-75f2689f9694&id=b726c366abfe62429ee3cdcd34d0c0fb98c33c3ea053480585bed71745412b56):
> I often don’t see my bot responses until after I post. they’re usually
time stamped correctly so I think it’s just a refresh issue?
### What changed?
Buzz Mobile now reconnects relay sessions after the app has remained
backgrounded beyond the existing 5-second grace period, even when the
session still reports a stale `connected` state. This makes resume
recovery independent of whether iOS runs the grace timer before or after
delivering `resumed`.
Reconnection is now based on elapsed background time rather than a
direct socket-health probe.
- If the app was backgrounded for at least the 5-second grace period,
the socket is presumed dead and the session reconnects regardless of
reported status.
- If it was backgrounded for less than that, a reported `connected`
status is still trusted.
In the sub-5-second window the socket is either genuinely alive, which
is the common case for a momentary background, or it is dead and the
client ping detects it within the two-interval worst case described
below. That is now a degraded-latency path, not a silent-forever path.
The mobile relay socket now uses `IOWebSocketChannel.connect` with a
30-second `pingInterval`. An unanswered ping closes the Dart socket
through the existing disconnect and reconnect path.
Detection takes up to two ping intervals, so about 60 seconds worst
case, not 30. One interval of idleness elapses and a ping is sent, then
a second interval elapses with no pong and the socket closes. Any
inbound pong restarts the first stage, so the clock measures idleness
rather than running on a fixed cadence.
### Why?
Buzz iOS can sometimes stop showing new bot or agent responses after a
phone has been locked for 5 to 10 minutes. When the user later posts a
message, the missing responses can appear all at once. iOS may suspend
Buzz before the short delayed cleanup that would normally close its
connection has a chance to run. Before this change, Buzz trusted the
resulting stale healthy status on resume and skipped reconnecting, so
the missing responses stayed hidden until a later post exposed the dead
connection.
A state-machine test with a stubbed connection reproduced this reported
pattern and showed that it matches this failure mode: the failed post
triggered a reconnect that fetched the missing messages. The same test
also checked the other candidate explanation, the bug tracked in
[#3053](https://github.com/block/buzz/pull/3053), where the relay has
closed the app's subscription. That state does not produce the pattern.
Posting succeeds and the user's own message appears, but nothing looks
for the missed messages, so they stay hidden. The test confirmed that
the missed messages were still available to fetch in that state, so the
missing step was a trigger to fetch them. This was not an end-to-end
reproduction on an iOS device or a live relay.
The new resume check covers the normal lock and unlock path. If the app
was backgrounded for less than the 5-second grace period, it still
trusts a connection marked as healthy. A dead connection in that window
is instead detected by the ping check, which can take up to about 60
seconds but prevents the app from remaining silently stuck. The ping
only runs while iOS is running the app, so it does not detect a
connection that died during suspension; the resume check owns the lock
and unlock path.
A pre-existing path also runs the same resume handling when network
connectivity returns while the app is already in the foreground. Because
the app was not backgrounded, this change does not alter that path,
which still trusts a connection marked as healthy and relies on the
slower ping check.
Recovery from a subscription that the relay explicitly closes remains in
[#3053](https://github.com/block/buzz/pull/3053), and the two changes
overlap in one file. Changes to how missed messages are backfilled or
replayed are out of scope.
### How is it tested?
Full mobile suite at base and head. Both runs have the same known
macOS-host-only failure in `ChannelDetailPage keeps follow mode off
while a tall newest message stays visible` at line 1053:
- Base: 1,021 passed, 1 skipped, 1 failed
- Head: 1,025 passed, 1 skipped, 1 failed
Added tests:
-
[`relay_session_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_session_test.dart):
long-background resume reconnect and within-grace control
-
[`relay_socket_liveness_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_socket_liveness_test.dart):
silent-peer disconnect and idle-but-healthy control
Mutation checks confirm that removing elapsed-background resume recovery
fails with one socket instead of two, and removing `pingInterval` leaves
the silent peer connected. Restored production code passes both
mutations' regression tests and the healthy idle control.

### What changed?
Mobile now recovers live subscriptions after retryable or rate-limited
relay `CLOSED` responses. It ports the existing desktop model: classify
terminal versus retryable closures, honor retry hints through a
session-owned rate-limit gate, retry with bounded backoff, and replay
visible-channel subscriptions first in bounded batches.
Channel refreshes also retain unchanged live subscriptions instead of
clearing and recreating them. This is desktop parity, not a new relay
policy.
### Why?
On reconnect or resume, mobile replayed its retained live subscriptions
while `channelsProvider` independently cleared and recreated roughly the
same set, alongside unread catch-up and open-channel requests. The relay
allows 50 REQs per 5 seconds, so users in many channels could
predictably exceed the budget. In live reproduction, 55 subscriptions
produced 9 rate-limit closures, 60 produced 18, and 80 produced 36.
Mobile then treated every live `CLOSED` as terminal, removed the
affected subscription, and never restored it. Channel updates could
remain dead until a later session reconstruction. This is the primary
causal chain behind
[BOT-1449](https://linear.app/squareup/issue/BOT-1449/buzz-mobile-posted-messages-dont-appear-until-leavingre-entering-the).
Desktop already handles this as normal transient pressure by classifying
closures, gating and backing off retries, pacing reconnect replay, and
retaining unchanged subscriptions. This change brings mobile to the same
recovery model while removing the avoidable request burst.
### How is it tested?
Full mobile suite: 721 passed, 1 skipped. Analyzer and formatting checks
pass. Required CI checks pass.
Added and updated tests cover `CLOSED` classification, retry hints,
rate-limit gating, bounded retry and reset behavior, terminal failures,
timer cleanup, history gating, visible-first batched replay, and
retention of unchanged subscriptions.

Brings the Flutter app's emoji and thread surfaces up to desktop parity.
## Emoji
- **Full emoji-mart dataset** generated from the same `@emoji-mart/data`
set desktop uses (1,870 emoji, 8 categories), committed as an asset — so
shortcodes, names, and keywords are identical across clients. `just
mobile-emoji-data` regenerates it.
- **Rebuilt the tray**: search (a Dart port of desktop's tiered
`emojiSearch` ranking, extended to names and keywords), a
frequently-used section, and one continuous scroll with pinned section
headers. The category rail is a shortcut into that list, not a page
switcher, and spans the full width the search field uses. Custom emoji
share the native glyph size and cell.
- **Reaction pills** match desktop's geometry, and the count shows at 1.
- **Emoji-only messages** render at 36px with 1.45em inline custom
emoji, matching desktop's `emojiOnly` treatment.
- **Positive-emoji burst** ported from desktop's `EmojiBurstProvider`,
suppressed under reduced motion.
## Threads
- **Top-down layout** — head first under the app bar, replies flowing
down, like desktop's thread panel. The old reversed list bottom-anchored
the content and jammed the head against the composer.
- **Tap a channel message to open its thread**; long-press still opens
the action sheet.
- **Live reactions.** The thread's relay query is one-shot and its
`kinds` filter carries only content rows, so a reaction event could not
reach an open thread at all, and `allMessages` was a snapshot frozen
when the route was pushed — a new pill only appeared after leaving and
re-entering, which refetched. The live channel events are now unioned
into the thread's list. The burst is also route-guarded, since the
channel timeline stays mounted underneath and was claiming it first.
- The `+` affordance follows the channel: replies stay bare until they
carry a reaction, and the head keeps a standing `+`.
## Keyboard
A deliberate downward drag past ~48px dismisses the keyboard; short
scrolls leave it alone. Applies to the channel list, the thread list,
and the compose bar (via a raw `Listener`, so it can't steal the field's
tap or selection drags).
True finger-tracking dismissal is out of scope — Flutter only offers
`manual`/`onDrag`, and 1:1 tracking needs a native `UIScrollView` proxy
plus Android's `WindowInsetsAnimationController`.
## Testing
`just mobile-check` and `just mobile-test` pass (965 tests). New
coverage for emoji search ranking, dataset parsing, the emoji-only
predicate, tray scroll/rail behavior, reaction pills and the burst, and
both thread fixes above. `just ci` green.

## Summary
Communities joined via an invite link never connect: the app dials
`ws://` on port 80 instead of `wss://` on 443 and sits on
"Reconnecting…" indefinitely.
`RelayConfig.baseUrl` is documented as an HTTP origin, but the two
onboarding flows disagree on what they persist:
- **Device pairing** validates and stores `https://` —
`pairing_provider.dart:657` throws on anything else.
- **Invite join** stores the relay URL straight off the invite link, and
`deep_link.dart:165` always emits `ws://` or `wss://`.
`wsUrl` only special-cased `https://`, so a `wss://` base fell through
to the plaintext branch:
```dart
final scheme = uri.scheme == 'https' ? 'wss' : 'ws'; // 'wss' is not 'https'
```
The claim request itself succeeds, because `_claimUrlFromRelay`
(`invite_join_provider.dart:242`) maps `wss → https` explicitly. Only
the socket path is missing that conversion — which is why the community
appears, correctly named, and then never loads.
The same `baseUrl` also feeds `/query` (`relay_session.dart:136`), media
upload (`media_upload.dart:765`), Blossom auth (`media_auth.dart:128`)
and `relayClientProvider` (`relay_provider.dart:113`), so those requests
were malformed too. Where port 80 *does* answer, it is additionally a
silent TLS downgrade after `validateInviteRelayUri` insisted on
`wss://`.
This folds the websocket schemes back to their HTTP equivalents in
`baseUrl` itself, so every consumer is correct by construction rather
than needing a second getter remembered at each call site, and
communities **already persisted** with `wss://` are repaired on read
without a migration. `community_icon_provider.dart:46` already performs
this same conversion locally.
One subtlety worth flagging for review: the normalization is derived in
the getter rather than applied in the constructor, so the constructor
stays `const`. The compile-time fallback at `relay_provider.dart:77`
relies on const canonicalization for a stable identity across rebuilds,
and Riverpod's `defaultUpdateShouldNotify` is `previous != next`
(`element.dart:361`), which falls back to identity for this class. A
`factory` constructor here yields a fresh instance per rebuild, which
tears down and resubscribes every listener —
`channels_provider_test.dart` catches it as an unexpected unsubscribe
during reconnect.

### Testing
`flutter test` — **705 passed, 1 skipped, 0 failed**
`flutter analyze` — No issues found
`dart format --set-exit-if-changed .` — 249 files, 0 changed
Run against the Hermit-pinned SDK (Flutter 3.41.7 / Dart 3.11.5),
matching CI.
10 new unit tests in `mobile/test/shared/relay/relay_config_test.dart`
covering both onboarding schemes, `http`/`https` passthrough,
non-default ports, and agreement between the invite and pairing paths
for the same relay.
Verified end-to-end against a self-hosted relay behind `tailscale
serve`, which terminates TLS on 443 and leaves port 80 closed. Relay
logs show the invite claim succeeding over HTTPS at the moment of
joining, while no WebSocket connection ever arrives — no `WebSocket
connection established`, no NIP-42 auth, no `kind:0` profile, no push
registration — across the relay's entire history, even though the member
row is present and correct. Port-80 refusals are not logged by
`tailscaled`'s netstack, which is why the retries leave no trace
server-side. Reproduced on both iOS and Android.

## Summary
- require invite relay destinations to be secure public origins in
production
- reject non-public and ambiguous IP literals before confirmation and
again before the claim request
- disable redirects for invite claims so a validated relay cannot
redirect the request elsewhere
- preserve explicit debug-only localhost support
## Validation
- pre-commit `dart format` and `flutter analyze`
- pre-push full mobile test suite: 666 passed, 1 skipped
- independent source reviews from Princess Donut and Mongo found no
remaining blockers
## Scope and residual risk
This fixes the mobile invite trust boundary without changing NIP-98 or
NIP-42. Hostnames are not resolved and pinned by this patch, so DNS
rebinding remains a networking-layer residual risk requiring
connect-time resolution/pinning.
