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.

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.

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.

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.

3ec6327618 fix(mobile): keep cached state with its community (#8349)
## Summary

One identity can be paired with several communities, but mobile keyed
several caches by pubkey only. Mobile keeps a single `ProviderScope` and
doesn't remount on a community switch, so one community's data showed up
in another, and some of it was published to the other community's relay.

- **Channel groups**: the second community showed the first community's
groups.
- **Read marks** (contexts, publishable set, NIP-RS client and slot
IDs): the first community's context IDs were merged into, and published
to, the second community's read-state slot.
- **Inbox done/unread rows and thread follows**: one shared 500-entry
cap, so activity in one community evicted another's entries.
- **Channel stars and mutes**: union-merged across communities and
published to every relay.

Every one of these is now keyed by pubkey + normalized community relay,
the same way channel sort already is.

**Switching communities.** The relay session rebuilds for the new
community before the previous community's managers are retired. Each
manager (groups, read state, stars, mutes) now checks that the session
still serves its own community before it publishes, merges a fetch, or
handles a live event. Previously, a pending publish flushed on dispose,
or an in-flight fetch, could cross into the next community.

**Old pubkey-only entries.** Channel IDs can repeat across communities,
so nothing tells us which community an old channel-keyed entry belongs
to:
- **Groups, stars, mutes and read marks** are dropped on upgrade, and
each community restores its own from its relay. Any change that never
reached a relay is lost, and a read mark the relay doesn't hold shows as
unread once. That's an accepted tradeoff: such changes would be very old
by now.
- **Inbox, thread follows, and read-state slot and client IDs** seed
every community, and the old entry is kept. The inbox and follows
entries are event IDs, which only ever match their own community. The
slot ID keeps each community publishing to the slot it already has on
its relay.

This PR also removes the **Pulse** feed (`features/pulse/` and the Nostr
filters only it used). Nothing in the app navigates to it anymore, and
its providers were among the community-unscoped caches.

### Related issue

None found.

### Testing

- Each affected store has a regression test through the real provider
that switches A → B → A. For groups, read marks, stars and mutes, the
test sets a value in A, switches to B while A's change is still pending,
and checks two cases: B's data arriving live and B answering A's
in-flight fetch. It asserts that nothing sent to B contains A's IDs, B
shows only its own value, and A comes back unchanged. Each guard was
removed in turn to confirm a test fails without it, except two that the
current switch order never reaches: the groups merge guard and the
read-state live-event guard.
- Upgrade tests cover each kind of old entry: dropped for groups, stars,
mutes and read marks, seeded for inbox, follows and slot IDs.
- `flutter analyze` is clean, and the full mobile suite passes in the
pre-push hook at `89ebfcc12`.
- Not yet exercised in the app.

91b1cc4761 perf(mobile): reuse the derived pubkey when signing auth events (#8460)
## Summary

Each relay `/query` signs a NIP-98 event, and each relay media image GET
signs a Blossom auth event. Both run on the UI isolate. `nostr`'s
`Event.from` derives the pubkey from the secret key on every call, which
is about a third of the cost of a signature.

Both call sites now pass the pubkey that `myPubkeyProvider` already
caches for the active key. The provider is derived from the same
`relayConfigProvider` state as the key, so the two always match.

This is the quick win. Moving signing to native secp256k1 or a worker
isolate would remove the rest of the cost, and that would be a separate
change.

## Before and after

AOT-compiled benchmark on Apple silicon, `nostr` 2.0.0 `Event.from`,
three runs of 50 signatures each:

| | ms per signature |
|---|---|
| `main` (pubkey derived) | 8.8 to 9.6 |
| this PR (pubkey passed) | 5.9 to 6.4 |

A scroll that shows 20 uncached relay-media images now spends about 60
ms less on the UI thread.

## Test

There are no new tests. The existing `queryRelay` test runs through the
real `relayConfigProvider` and `myPubkeyProvider`, and asserts the
signed event's pubkey for one identity. It does not verify the signature
or switch identities, and it would still pass with this optimization
removed. The media tests build the service directly, so they only cover
the fallback where the pubkey is derived.

Review traced the pairing instead. Both the key and the pubkey come from
`relayConfigProvider`. `_postForEvents` reads both and signs with no
await in between, and the media provider watches both. So the key and
pubkey change together on community switch and sign-out.

## Validation

- `flutter analyze`
- Full mobile suite: 3,534 passed.

**Human test:** Wes ran #8456, #8460 and #8462 together on the simulator
with his real account and confirmed they work.

b6aa5539e3 feat(mobile): account onboarding, key recovery and hosted reconnect (#8375)
## Behavior

Adds optional mobile Builderlab sign-in, identity backup/recovery,
community discovery/creation, and account-aware reconnect. **Builderlab
features are disabled by default:** when `BUZZ_AUTH_DOMAINS` is unset or
empty, account login, creation, backup/recovery, reconnect prompts, and
background account restoration are hidden/disabled. QR/code pairing,
links, and invites retain Nostr-only entry. Saved account state is
retained for later opt-in.


`--dart-define=BUZZ_AUTH_DOMAINS=communities.buzz.xyz,communities.public.builderlabstaging.xyz`
opts those DNS domains and their subdomains into required account setup.
The same policy gates pairing, deep links, durable community admission,
and reconnect. A nonempty list enables Builderlab features;
`BUZZ_BUILDERLAB_URL` alone does not. Enabled flows still require their
backend services. Existing Nostr relay authentication remains mandatory.

`BUZZ_HOSTED_RELAY_AUTH=true` enables scoped relay assertions and
reconnect prompts only for configured authentication domains. Configure
assertion issuance and each community's issuer binding before enabling
assertions; enable relay enforcement last. Account credentials stay at
Builderlab. Wrong-account recovery preserves keys; failed writes are not
replayed; authentication is bounded by request deadlines.

Hosted flows preserve keys across cancellation/restart, reconcile
interrupted creation/invitation acceptance, and support manual nsec file
import/export. Account identities are scoped to backend and
authenticated subject; reusing an existing local key for an unbound
account requires an explicit selection. Recovery reconciles the
advertised and recovered inventories before automatic selection.
Successful self-hosted admission retires its pending key, and iOS
startup removes interrupted export files. Adds authenticated relay `GET
/operator/communities/joined` for the companion Builderlab membership
endpoint.

## Validation

- Follow-up review repair at `66a12ac92`: self-hosted entry presents
readable choices and import despite incomplete enumeration, while
generation still requires a complete empty inventory; explicit selection
uses exact-key lookup. Consuming a value-equal duplicate now advances
dispatch. Reconnect requires an existing account binding or a
subject-scoped backup receipt before signing an assertion, and pins the
subject inside the serialized account request. An empty different
account is refused without sending key proof. Focused checks: configured
domains 58 passed; default 49 passed, 9 hosted-only skips. Separate
isolated mutations fail the incomplete-inventory sheet, exact-key reuse,
duplicate dispatch and reconnect journeys (including an
empty-account-only bypass); restored controls pass. Evidence uses
synthetic storage/network boundaries, not physical Android or live
backend association. All mandatory commit/push hooks passed; fresh
GitHub CI is pending.

- Bounded review repair at `d3cc0003f`: incomplete secure-storage
enumeration now blocks automatic identity generation while explicit
known-key reads retain their fallback; declined/failed onboarding links
release the queue; HTTP 429/5xx keeps Retry regardless of response
encoding. Default app-gate coverage exercises a bind link followed by
ordinary community entry. Focused checks: configured domains 47 passed;
default 38 passed, 9 hosted-only skips. Removing the three production
fixes in an isolated source/Git/build copy fails the
identity-resolution, declined/failed queue, and Retry journey
assertions; clean and restored controls pass. Storage and HTTP failures
are synthetic; physical Android and live outage behavior were not
exercised. Published after all mandatory commit/push hooks passed
(mobile analysis/tests, branch-skew and file-size gates); fresh GitHub
CI remains pending.

- Existing whole-PR source review cleared the reconnect defects at
`fb15d5b82`.
- Domain-policy increment: focused environment, entry, app-gate, pairing
and onboarding journeys pass with empty and configured domains. Existing
pairing provider/page tests pass. Changed Dart files analyze cleanly.
- Isolated source/Git/build mutation: forcing paired credentials through
hosted login fails the default-build journey; clean and restored
controls pass. CI now runs configured-domain journeys in addition to the
default-build suite.
- Integrated main through `5b433d929` at `0067c069c`, including its
pinned Flutter upgrade. Preserved the PR welcome UI with the updated
transition API and added Material surfaces around onboarding
selection/consent rows. Focused post-merge runs pass in both
configurations; all mandatory local push gates passed (mobile
analysis/tests, Rust tests, desktop-native checks, branch-skew and
file-size checks).

- Merge-review repair at `a315bce11`: focused identity/storage/admission
and widget journeys pass, including account switching with an empty or
already-bound second account, explicit reuse, and self-hosted
removal/rejoin with another key. Default-domain journeys pass too
(hosted-only cases intentionally skip there).
- Isolated source/Git/build mutation checks: bypassing account scoping,
reuse consent, pending-key retirement, or recovery inventory
reconciliation fails the relevant journey/invariant assertions; clean
and restored controls pass.
- Native `RunnerTests/IdentityFilePluginTests`: both tests pass on the
iPhone 18 Pro iOS 27 simulator with an isolated app identifier. At
`24a0dcaac`, the picker journey seeds residue in Library/Caches,
matching path_provider_foundation, and verifies plugin startup removes
it while preserving an unrelated file. The earlier tmp-only fixture did
not exercise the actual export location. This is synthetic native
cleanup/picker evidence, not a real terminated-share or live account
round trip.

- Follow-up: Caches and tmp cleanup; fallback to individually known
identity slots when Android bulk enumeration fails; explicit replacement
of a refused self-hosted key preserves its original before swapping the
retry slot. Configured-domain journeys/invariants: 34 passed; default:
31 passed, 3 hosted-only skips. Isolated enumeration/retry mutations
fail with passing controls. Bulk-read fallback preserves but cannot
enumerate arbitrary other-account slots until bulk reads recover.

- Configured-domain CI exposed a stale pairing-status assertion after
account scoping. The repaired test checks the admission mismatch,
preserved account/transfer keys, and no admitted community. The
configured-domain CI selection passes locally (56 tests); removing the
production mismatch guard fails the updated test, with clean/restored
controls passing. This is synthetic coordinator evidence, not physical
QR acceptance.

- Final review repair (`40e1e6101`): native iOS export creation uses
atomic complete file protection; normal and restart cleanup remain.
Account/policy/claim HTTP uses one 30-second total deadline with request
abort and body cancellation. Removed the unrelated NIP-FA spec edit.
- Focused account/admission/export tests: 25 pass; configured-domain
account/admission/onboarding journeys: 33 pass. Isolated deadline and
native-dispatch mutations fail, with passing clean/restored controls.
Native export/picker tests: 2 pass on iOS 27 simulator. The real
file-protection attribute assertion is physical-device-only because
simulator provides no Data Protection attribute; locked-device
protection and interrupted real sharing have not been observed.

- Opt-in UI: configured-domain CI selection passes (57 tests); default
selection passes (7 tests, 10 hosted-only skips); URL-only plus
whitespace/empty domains passes (6 tests, 9 hosted-only skips). Changed
Dart files analyze cleanly. Independent mutations that unconditionally
initialize the coordinator in the app gate, welcome entry, or link form
fail the default journey; clean/restored controls pass.
- Native welcome screens exercised on iPhone 18 Pro / iOS 27 simulator
in default and configured builds: default exposes community link / QR /
pairing code only; configured build additionally exposes Builderlab
connection and community creation. No live hosted login was exercised in
this check.

- Delivery at `e48fe73a9`: all mandatory push hooks passed (full mobile
analysis/tests, Rust tests, desktop-native checks, branch and file-size
checks). GitHub checks had not yet populated at the immediate post-push
snapshot.

## Remaining draft gates

Native QR/browser-return acceptance remains unverified for this
revision. Optional Builderlab onboarding still needs backend
backup-status and joined-community routes, recovery
policy/configuration, and real backup/recovery/reconnect acceptance. The
empty-domain build removes these services as prerequisites for ordinary
pairing; it does not make the optional hosted flows backend-ready. Human
acceptance and current CI are still required before merge.



Review dispositions retained: production auth-domain configuration must
use supported community mappings; enabling `builderlab.xyz` does not add
support for `buzz.block.builderlab.xyz`. Recovery after genuinely losing
an Android Keystore key remains a follow-up, not a newly implemented
capability.


Human acceptance steps: build once without `BUZZ_AUTH_DOMAINS`
(including with a previously saved account) and confirm no Builderlab
controls/restoration while ordinary link and QR/code entry work. Build
with supported domains and confirm connection/creation appear; exercise
browser return and live backup/recovery/reconnect. On physical iOS,
exercise export and interrupted sharing/locked-device protection. Record
results before marking review complete.

819dd7924f fix(mobile): bump Flutter 3.47, resolving memory leak (#8419)
With accessibility semantics active, opening and leaving channels
retained disposed composer overlay states through Flutter’s semantics
traversal map. Those states kept departed route and message trees alive.
This upgrades the pinned Flutter SDK from 3.41.7 to 3.47.7, which
includes [the upstream
fix](3c96406cc4).

Includes SDK compatibility and formatter changes, preserves CocoaPods
integration, and gives create-channel radio lists a Material ink surface
required by the newer framework. Widget regressions verify both the
framework portal and the production channel/composer lifecycle: departed
routes, composer elements, and portal states are collectible while their
application’s semantics owner remains alive.

Related issue: no matching open issue or PR found.

### Validation

- [Current-head CI
passed](https://github.com/block/buzz/actions/runs/39085320351): all
mobile test shards, checks, Android APK, iOS release build, and native
simulator tests.

- Framework regression fails on Flutter 3.41.7 with three retained
states and passes on 3.47.7.
- Signed native Debug iOS Simulator build and paired-community
navigation replay: after 18 channel visits and forced GC, retained
disposed portal keys fell from 18 to 0 and route instances from 19 to 1.
- Review follow-up: all 365 focused channel/overlay tests, analyzer, and
complete mobile pre-push checks passed.
- Full local CI passed before the test-only review follow-up, including
Rust and desktop validation, frontend builds, analyzer checks, 3,499
mobile tests (four skipped), and the separate unconfigured-push test.

The replay used iOS 26.5 Simulator with accessibility semantics enabled,
CPU profiling disabled, and Debug/JIT builds. The before app was a
preinstalled emoji candidate; the after app uses this branch. Object
retention and the focused regression establish the fix; absolute heap
differences are not a controlled release-memory measurement. Android
native execution was not tested.

### Create-channel compatibility

The radio groups retain their layout after switching their container to
Material.

93ffc37cbd feat(mobile): find people by name through the relay's name-only profile search (#8333)
🤖
## Summary
In the mobile app, searching for "wes" did not find Wes. People search
matched text anywhere in a profile, including the image data of a shared
default avatar. Many agent profiles use that avatar, so they filled the
results and the real Wes never appeared.

Now every people search in the app uses the relay's new name search: the
Search page, adding channel members, new messages, and @mention
suggestions. It matches only a profile's name and display name and puts
exact names first. The desktop app (block/buzz-app#1084), agent tools
(block/buzz-app#1124) and the CLI (#8331) make the same change.

Compatibility: a relay without the new search answers 404 or 405. That
search uses the old search, and so do later searches on the same relay
for five minutes; then the app tries the new search again, so a relay
that is upgraded while the app runs is used soon after. A query or
result count that the new search cannot take also uses the old search.
Other errors are shown as before.

Order: search results keep the relay's ranking, so "Wes" comes before
"Abe Wes". Before, the Search page and the member and new-message
pickers sorted results by name. The list with no query is still
alphabetical. Each screen still applies its own filters.

Not in scope: the community invite screen accepts only an npub and has
no name search, so this PR does not change it.

### Related issue
Relay endpoint: #8301. This PR does not depend on it; either can merge
first.

### Testing
- Relay session tests: the name query goes to the new search with a
signed request; a 404 falls back and stays on the old search until the
retry time; a 405 falls back; other errors do not fall back; an
unsupported result count uses the old search.
- Updated tests for add members and @mention search, and a test that
search results keep the relay's order while the browse list stays
alphabetical.
- `just mobile-check` and the relay, channel, mention, invite and search
tests (1,962) pass.
- No screenshots: results look the same; only which people are found
changes.

b1d60f98e2 Bring synced Solo chats and projects to mobile (#8337)
## Summary
Bring desktop Solo chats and project organization to mobile, with synced
collapsible sections, shared unread highlights and tab badges, agent
selection, shared search, native iOS creation sheets, and inline typing
bubbles that transition into replies.

Resolve Solo placement for every chat entry route, retain encrypted
organization snapshots for offline reading, and let users resume or
discard unfinished chat and project setup without deleting existing
messages.

### Related issue
Related: #6565; expandable agent transcripts remain separate work.

### Testing
- Fresh Solo read state seeds each active chat from its captured initial
last-message timestamp before exposing row/section/tab unread state.
Baselines survive intervening channel updates and reset across
identity/community boundaries while surviving read-state readiness
changes. Regressions cover multiple chats, events before read-state
readiness and during/after seeding, and identity changes; removing
either the seed or the display gate fails them.
- Chat completion reconciles a retained Solo-save journal even when
placement is already confirmed. False/throwing cleanup regressions
ensure the outer intent remains until reconciliation and only one
placement is published. Typing terminal-close loops remain bounded; the
retry budget resets after an uninterrupted eight-second health interval
or transport reconnect.
- Typing retry budgets reset after sustained recovery; invalid Solo
updates retain cached rows with a retry warning that survives failed
refreshes. Project names use the editors’ 120-grapheme limit, including
emoji and combining characters. Regression coverage exercises repeated
recovery, invalid live/refresh heads, and character-limit boundaries.
- Rebased onto current main, preserving the newer Search controls,
Huddle timeline filtering, and message-media layout.
- Failed project journal writes reload storage before claiming recovery
and reopen the entered name for retry. Typing subscription rejections
are caught; terminal closures clear stale indicators and retry with a
bounded backoff, canceled on disposal. Regression tests cover both
false/throwing storage writes and initial/late subscription rejection.
- Explicit ordinary destinations skip optional Solo lookup waits.
Generic destinations perform one bounded lookup in the destination
(search no longer duplicates it); an unavailable classification falls
back to ordinary sending per the product owner's explicit choice.
Positively identified Solo destinations use Solo providers.
- Terminal Solo subscription closure preserves cached rows and exposes
live-update Retry. Page coverage verifies warning visibility, usable
rows during recovery, and a subsequent terminal close. Removing the
warning or the immediate ordinary-route guard fails its regression.
- Generic channel entries share an ordinary default when Solo
classification is unavailable, per the requested product behavior. Known
Solo placement takes precedence; callers can explicitly require
unresolved placement to remain blocked. Bounded initial lookup preserves
known Solo deep-link routing.
- Dirty newest snapshots and offline-save warnings survive transport
reconnects; Retry persists that same event even if the relay returns an
older head. Community changes replace the service, and agent-directory
reconnect refresh remains intact.
- Pending-save discard reloads failed removals. Repeated reconnect
testing confirms typing subscriptions are released on provider rebuild
and disposal; removing the existing cleanup fails the regression.
- Ordinary Home/create routes explicitly preserve private-channel
sending during Solo failures; identified Solo sends use the Solo sender
and explicit unresolved routes remain fail-closed. Solo unread replies
beyond the initial 200-event page are loaded through the oldest-unread
boundary.
- Chat/project/agent cleanup reloads failed removals, retains
same-process recovery, and protects replaced records. False/throw
regressions verify retries do not duplicate creation or membership.
Route, unread, and cleanup guard-removal mutations each fail their
regression.
- Ordinary channels, DMs, and forums remain sendable when optional Solo
sync fails; explicit unresolved placement stays blocked. Controlled
cache races retain the newest verified snapshot, keep usable chats
visible, and retry offline persistence without stale writes. Both
protection-removal regressions fail as expected.
- Confirmed journal cleanup checks false/throwing removal and
exact-record identity. Interrupted agent choices are visible
immediately, identify the saved agent, and cover Resume/Later/Discard
with accessible name/key-fallback controls.
- Notification deep links preserve the contiguous history cursor;
same-second messages infer the newest agent consistently. Failed
offline-cache writes surface Retry, with false/throwing storage failures
and offline restart covered.
- Composite history cursors cover 350 same-second events plus older
history; removing the ID cursor makes the regression fail. Agent changes
now journal before granting access, with restart/failure and
Resume/Later/Discard widget coverage. Signed malformed profiles remain
isolated.
- Native iOS avatar tests passed on the simulator: visible-row loading,
three-request concurrency, streamed byte limits, response validation,
downsampling/pixel limits, cancellation, and visible avatar updates.
- Solo and Home share observed-event/read-marker logic. Widget coverage
verifies unread rows, collapsed-section indicators, the tab badge before
first Solo visit, message/thread reads, forced unread, and filtering
archived/nonmember/unplaced chats.
- Chat intent is saved before ownership and organization preflight;
tests cover interrupted ownership lookup and a disconnect while the
native creation form is open.
- Mobile analysis, formatting, file-size checks, and full mobile tests
passed at `1d4c41354`.
- Project creation persists its encrypted name/UUID before connectivity
checks or relay reads. Restart tests cover Resume/Later/Discard, scope
isolation, stale-intent rejection, and lost acknowledgements. Removing
the pre-network save makes all four production-flow regressions fail.
- Regression coverage includes notification/Activity routing, inline
replies, unknown-placement send protection, restart recovery/discard,
and encrypted offline cache isolation/refresh.
- Earlier feature build exercised on a physical iPhone with existing
account/community data; review follow-ups have not been reinstalled on
the device. UIKit agent-row accessibility checks passed on an iOS
simulator.
- Earlier cross-platform `just ci` stopped on the existing `buzz-acp`
test `signals_cancel_startup_turn_and_pending_stdin_without_hanging`
(process exit-code assertion); no Rust production changes are included
in this PR.

### Remaining review limitation
Agent discovery is bounded to 10 pages / 1,000 profiles with automatic
retries disabled. Owner-scoped discovery remains open because the
current relay ignores `#auth` filters; supporting that query requires a
relay change.

### Snapshots
Sample data, shared Flutter/Android surface. Native iOS uses platform
sheets and controls.

d61fe2071d Use native UIKit scrolling for iOS photo carousels (#8361)
Builds on the mobile polish merged in #8359; this PR now targets `main`.
On iOS, inline photo galleries now use a UIKit collection view for
dragging, deceleration, and snapping. Photo taps retain the existing
full-screen viewer and reply/more actions; gallery scrolling continues
to fade the message avatar. The final photo stops at the full message
gutter rather than the smaller gap between photos. Android keeps the
current Flutter carousel.

Visible cells subscribe to continuing frames from Flutter's existing
authenticated image providers, preserving animated GIF/APNG/WebP media.
Request IDs fence late frames and cancel subscriptions on
reuse/disappearance/disposal. A four-slot bound includes retired
unresolved loads until their transport terminates. Shared media fetches
now use abortable HTTP requests with a 30-second deadline through
response-body completion, so stalled requests release their slots
without leaving live transports behind; native eager precaching is
disabled so it cannot bypass that bound. Frame conversion coalesces to
the newest pending frame. Native cells expose photo labels and positions
to VoiceOver, support RTL, and preserve the selected photo during
resizing.

Validation:
- Mobile formatting and analysis passed.
- Native simulator regression checks passed for geometry, RTL, snapping,
taps, frame replacement, cancellation, and resizing. The native CI lane
now runs the carousel executable.
- Full mobile suite and pre-push gates passed, including two-frame GIF
delivery, delayed-provider bounds/cancellation, real HTTP
stalled-header/body recovery with four requests maximum, disposal, and
unconfigured-push tests.
- Signed iPhone Release build of the frame/subscription implementation
passed. Physical iPhone testing covered the earlier carousel/gutter
revision; the new animation/cancellation changes have local Flutter and
native simulator coverage, not a new physical-device journey.
Preview-only signing overrides preserve its bundle/Keychain group;
production entitlements are unchanged. Local provisioning excludes
production push/App Attest capabilities.
- Full `just ci` was started but stopped after unrelated Rust/desktop
compilation consumed about 5 GB; broad CI is incomplete.

Device build required local Xcode 27 workarounds: iOS 16 deployment
target and a generated swift-secp256k1 cache compatibility edit. Neither
changes repository source.

8222e99915 fix(mobile): keep thread references consistent across push and Inbox (#8332)
Follow-up to [#8294](https://github.com/block/buzz/pull/8294). Malformed
trailing thread tags could make a notification open the right thread
while Flutter indexed its reply elsewhere; uppercase references could
similarly miss lowercase event IDs.

Share one validated thread-reference parser between the mobile timeline,
Inbox, and feed helper. It ignores malformed markers, keeps the last
valid root/reply, and normalizes lookup IDs to lowercase. Native push
parsing now uses the same casing. Existing thread fixtures use valid
event IDs so they continue exercising real thread relationships.

Add RunnerTests coverage for the production native-to-Flutter argument
conversion, including buffered cold-start navigation and omitted
optional thread IDs, and run it in the native CI lane.

### Validation

- New parser and Inbox regressions cover malformed markers and uppercase
references. Widget regressions open and highlight the exact reply for
valid, uppercase, and trailing-malformed tags.
- After integrating [#8106](https://github.com/block/buzz/pull/8106),
Flutter analysis and the complete mobile suite pass: 3,337 tests, four
existing skips. Integration preserves per-event read predicates and
migrates incoming thread fixtures to valid IDs. An unchanged
keyboard-history test also failed with main's original parser; recording
reads before the scroll transition fixes its timing assumption while
retaining visibility assertions.
- Native package tests passed (127 tests), and both Runner bridge tests
passed on an iOS simulator with Xcode 26.5. Removing the production
`threadRootId` assignment made the bridge regression fail; restoring it
passed. Native code is unchanged by the main integration.
- [Current-head CI
passed](https://github.com/block/buzz/actions/runs/38659307247),
including Mobile and Mobile Swift. [Codex
review](https://github.com/block/buzz/pull/8332#issuecomment-6181458528)
and [security
review](https://github.com/block/buzz/pull/8332#issuecomment-6181449235)
found no issues on the integrated commit. [Owner
approval](https://github.com/block/buzz/pull/8332#pullrequestreview-5526812957)
covers the exact integrated commit.
- Standards and spec reviews found no blockers, including the merge
resolutions and test adjustments. Validation is scoped to mobile/native
per VISION_MOBILE; unrelated repository-wide checks were stopped, not
counted as passing.

The bridge test covers serialization and buffering, not end-to-end APNs
delivery or app launch. No new physical-device acceptance is claimed;
routine post-merge dogfood remains human-owned.

9b1c4f98e2 🤖 perf: bound long-thread aux reads and make query deadlines terminal (#7854)
Long threads (over ~100 replies) time out in desktop. The aux hop that
loads reactions and other e-tag references builds its filter as one
`tags @> …` term per id, joined with `OR`. Past about 100 ids the
planner switches to walking each partition's primary key backward,
expecting to stop early. When few rows actually match, it scans the
whole community. With a dirty GIN pending list, a 188-reply thread never
finishes.

### What changes

- **Set-based e-tag reads (`buzz-db`).** The aux e-tag query now puts
the id set behind a `MATERIALIZED` CTE and matches with `ANY`. Each
e-tag read also runs under a transaction-local `statement_timeout` of 20
s.
- **Terminal timeout contract (`buzz-relay`).** When a read hits the
deadline, the client gets a terminal timeout (`CLOSED` for REQ, the
timeout error for COUNT and search), not a retryable failure.
- **Subscription lifecycle (`buzz-relay`).** The per-connection
subscription map lock is now the lifecycle lock. Claims, replacement,
client `CLOSE`, owner-checked timeout and search cleanup, revoke, and
connection teardown all change the map, the registry, topic refcounts
and terminal frames while holding it. As a result, a timed-out
subscription's `CLOSED` goes out before any replacement with the same id
can claim it, and claims made after teardown are refused.
- **Dropped terminal frame disconnects (`buzz-relay`).** If the `CLOSED`
for a retired subscription (owner-checked timeout or channel eviction)
can't be queued, the relay cancels the connection instead of leaving the
client holding a subscription that will never receive fan-out. A
client-initiated `CLOSE` ack is exempt.
- **COUNT under the same deadline (`buzz-db`).** The fast COUNT path
runs e-tag counts under the same transaction-local 20 s cap as SELECT,
so WS COUNT and HTTP `/count` produce the terminal timeout too.
- **Replica reads surface the deadline (`buzz-db`).** When a
replica-routed read is cancelled by `statement_timeout` (SQLSTATE
`57014`), the error is returned instead of re-running the query on the
writer, which would run the same slow statement. Other replica errors
still fall back to the writer.
`PLANS/REPLICA_FULL_READ_ROUTING_DESIGN.md` records the exception.
- **Deadline handling (desktop).** Only the relay's `query timed out`
counts as a query deadline. A client-side `request timed out` stays
retryable. For one-shot reads a deadline is terminal: the global query
retry (budget 1), thread-replies retry and reaction hydration don't
re-send the same slow query. Reaction ids held back by a deadline are
released when the channel is opened again, so reopening retries them
while same-channel re-renders don't. Live subscriptions, in both the
renderer and the native archive-sync socket, keep treating a deadline
`CLOSED` as transient: they back off and resubscribe with the same
filter instead of being dropped.
- **Deadline handling (mobile).** Mobile recognizes the deadline on both
transports: HTTP `503 {"error":"query timed out"}` and the WS `CLOSED`
reason.
- The root `ProviderScope` retry policy returns no retry for deadline
errors and keeps Riverpod's default backoff for everything else.
  - Background thread-summary recounts don't retry a deadline.
- Forum posts polling pauses while the last load settled on a deadline;
reopening the forum retries.
- A channel's newest-window load surfaces a deadline instead of falling
back to legacy WS history, and the channel list's batched queries return
"unavailable" on a deadline instead of fanning out to per-filter
fallbacks. An unavailable batch is not treated as empty. Known
last-message timestamps and unread state are kept, and unread catch-up
moves `lastMessageAt` forward (never backward) the same way live events
do, so a cold start with no known timestamp still gets one.
- A live subscription that gets a deadline `CLOSED` backs off and
resubscribes with the same filter. History requests still fail on it.
- Settled load failures show a Retry control, matching desktop's
thread-replies error card: a shared `LoadErrorView` on the channel
timeline, forum thread and forum posts list, and an icon button beside
the thread replies summary. While the thread query has no value, the
thread page shows the route snapshot plus live, cached and optimistic
replies, with the loading or error status still visible.
- Other re-sends (reconnect, foreground resume, live events, the unread
backstop, scroll) are not suppressed; each is bounded by the relay's 20
s statement deadline.
- **Long-thread seeder.** `just seed-long-thread [replies]` posts one
thread (default 187 replies) with some reactions to the local dev relay,
for reproducing long threads in the apps. It uses a throwaway key,
refuses non-loopback relays and ignores ambient `BUZZ_*` credentials.
Writes are paced to fit the stock relay rate limit.

**Lifecycle concurrency.** The lock serializes one connection's
subscription changes. Other connections can still be delayed by pressure
on the shared pubsub command queue, and by serial eviction loops waiting
behind a blocked connection. This PR does not claim strict isolation
between connections.

**Recovery vs. load.** Clients stop automatic retries of the same
one-shot read, but they don't remember deadlines across other triggers:
reconnect, resume, live events and the unread backstop can each send the
read again later, bounded by the 20 s statement deadline. A live
subscription that hits the deadline resubscribes with its original
filter under the existing 1–30 s backoff, and against a filter that
keeps timing out it retries at the 30 s cap indefinitely, so the worst
case is one bounded query per subscription every 30 s. `since` is
deliberately not advanced to now on resubscribe, because that would skip
events missed while the subscription was closed. Unchanged from `main`:
when mobile's channel history sync fails with cached messages available,
the cached messages are shown without the error or Retry control.


### Benchmark

Local reproduction on an isolated bench stack (not committed):
- PG16, migrations applied, one 188-reply thread plus 5M background
events in the same community.
- Each request replays the desktop thread-replies filter through the
relay, with `include_aux` on. Times are total ms for 3 runs, with a 60 s
client cap.

GIN pending-list state is controlled with `VACUUM` (clean) or by
refilling the pending list (dirty), and recorded per partition with
`pgstatginindex`. Dirty runs held 402 pending pages on every partition's
tags index at the start and end of each matrix. Clean runs held 0–1
pages (relay startup writes).

Baseline `origin/main` `b37e47721`; this PR at `5f2650f5f`, whose e-tag
read builders are identical to the current head. At head `1ad81d868`
against `origin/main` `15d44dcce`, limit 200 measured 145–179 ms clean
(`main` 683–715) and 4.41–4.51 s dirty (`main` timeout ×3).

Every completed cell returns the same signed event set: 209 events, 187
replies at limit 200. With `include_aux` off, every cell is ≤66 ms. The
thread-window loader (`select_aux`) is unchanged from `main`, and its
timings and captured plans match `main`'s.

Actual aux-hop statements captured from each relay binary with
`auto_explain` (analyze + buffers), execution ms:

| build | clean, 100 ids | clean, 188 ids | dirty, 100 ids | dirty, 188
ids |
|---|---|---|---|---|
| `main` (N-way `OR`) | 40 | 298 | 28785 | 62892 |
| this PR (`MATERIALIZED` fence + `ANY`) | 23 | 45 | 1992 | 3539 |

**What the fence changes**
- On `main`, the planner combines `ORDER BY created_at … LIMIT` with an
overestimated match count and walks each partition's primary key
backward, expecting to stop early. With few real matches it scans the
whole community: the dirty 188-id statement touches ~4.9M shared buffers
on `main` vs ~0.6M with the fence.
- The fence prevents that early-stop plan. Across the measured cases
(1–188 ids, both pending states), the planner used the GIN tags index.
The fence doesn't force GIN in general; a broad enough filter could
still get a different plan.

**Tradeoff:** the fence materializes every match before sorting. In this
bench small limits stayed within run-to-run noise of `main`. A single
hot id (5,000 reactions, limit 100) measured 30–34 ms unfenced vs 35 ms
fenced.

**Deadline:** each e-tag read (SELECT and COUNT) runs under a
transaction-local `statement_timeout` of 20 s. It only tightens: a
shorter operator timeout (`BUZZ_DB_STATEMENT_TIMEOUT_MS`) is kept. It's
a per-statement limit, not a per-request one, so a request that runs
several pages or hops can take longer than 20 s in total. The benchmark
does not force the deadline.

f7ff4294fa feat(nip-fi): harden Blossom kind-24242 verifier to NIP-FI spec (#7288)
Brings `buzz-media`, `buzz-relay`, all first-party kind-24242 minters,
and desktop token minting into compliance with [NIP-FI
§kind-24242](https://github.com/block/buzz/blob/main/docs/nips/NIP-FI.md).

## What changed

**`buzz-media/src/auth.rs`**
- Add `BlossomStrictness` enum (`Strict` | `Permissive`). `Strict`
applies full NIP-FI rules (active modes); `Permissive` preserves
pre-NIP-FI Off-mode behavior byte-identical [FI-INV-15].
- Rewrite `verify_blossom_auth_event_for_verb` with count-based
cardinality: exactly one `t`/`expiration`/`server` in `Strict`;
duplicate `x` also rejected. `Permissive` keeps main's boolean semantics
exactly: any valued `t` other than the verb (including `""`) rejects,
valueless `t` is ignored.
- `Strict`: mandatory `server` tag on all proofs (upload + read); absent
or mismatched → `evidence_rejected` (`ServerMismatch`).
- `Strict`: 60-second proof window (`now - created_at <= 60s`,
`expiration <= created_at + 60s`). `Permissive`: 3600s / optional
server.
- **[F1]** Permissive server validation uses any-match semantics: a
proof with multiple `server` tags is accepted if any tag matches the
bound host. This restores origin/main base behavior. Strict
duplicate-rejection unchanged.
- **[F1 compat]** Permissive server gate uses `server_values.is_empty()`
(valued tags only) rather than `server_count > 0` (includes valueless
tags). A lone valueless `["server"]` tag is treated as absent in
Permissive/Off mode, matching pre-NIP-FI base behavior [FI-INV-15].
- **[F4]** Valueless `x` tags in Strict get reads are tracked before
`filter_map` so they cannot become absent scope (host-wide
authorization). Any `x` tag present in Strict must contain the exact
requested sha256.
- **[F3 unit]** Cases A–D in `auth.rs` are helper-level unit tests: they
call `verify_blossom_upload_auth` and `verify_upload_hash_only`
directly. They do not enter the upload pipeline
(`process_upload`/`process_video_upload`). Retained as helper evidence.

**`buzz-media/src/error.rs`**
- Add `DuplicateTag(&'static str)` variant.
- Add `blossom_denial_kind()` method: classifies each auth error as
`MissingEvidence`, `EvidenceRejected`, or `AuthorizationDenied`.
Non-auth errors return `None`.
- `IntoResponse` retains the legacy JSON 401 shape [FI-INV-15].

**`buzz-relay/src/api/media.rs`**
- Add `MediaDenial(MediaError, BlossomStrictness)` wrapper mapping to
byte-exact NIP-FI fixed responses in `Strict`; falls through to legacy
JSON in `Permissive`.
- `blossom_strictness_from_state()` selects `Strict` when
`state.config.nip_fi.is_enforce()`, otherwise `Permissive`. Strictness
is threaded through the `admit_nip_fi_http_on_state` NIP-98 closures on
upload and read, and through the post-admission X-SHA-256, hash-binding,
and membership denials.
- `extract_blossom_auth` keeps first-value `Authorization` extraction;
Enforce rejects repeated fields at the `admit_nip_fi_http` cardinality
gate, and Off keeps legacy behavior [FI-INV-15].
- Both membership-denial call sites use
`media_denial(RelayMembershipRequired, strictness)` so Strict mode
produces the correct fixed-text response.
- `upload_blob` serving-write fence conversion (`:406`) uses
`map_err(|e| media_denial(e, strictness))` — a community fence committed
between auth admission and lease acquisition no longer resets Strict to
Permissive.
- Mode-driven regressions in `mod postgres_tests` (selected by the
nextest `postgres-ci` profile via `test(/postgres_tests::/)`, `#[ignore
= "requires Postgres"]`), run through the full relay router with a real
Enforce verifier and assertion: Enforce rejects Permissive-only proofs
(300s lifetime, missing `server` tag) on both upload routes and reads
with `evidence rejected`; Off accepts the same proofs with pre-NIP-FI
responses; DenyProtected answers 503 before any proof check; membership
denials are `authorization denied` text/plain in Enforce and exact
legacy JSON 403 in Off, with a member positive control. GET and HEAD are
each discriminated (HEAD with a suppressed body). Both upload routes pin
the handler's `X-SHA-256` missing/malformed/unsigned and post-body
hash-mismatch denials in both modes. Off rejects an empty-valued `t`
beside a valid one with legacy 401 JSON in either order, and ignores a
valueless one. Exact status, Content-Type, challenge, and body bytes are
pinned.

**`buzz-media/src/upload.rs`** (`mod minio_tests`)
- **[F3 pipeline]** Four tests exercising the actual post-body call
sites (`process_upload` `:85`, `process_video_upload` `:413`) with real
MinIO I/O: buffered/streaming × expired-proof-accept +
mismatched-hash-reject. The positive cases use
`fresh_strict_upload_auth` (`created_at = now-58`, `expiration = now+2`,
lifetime = 60s) — Strict-admissible at sign time — followed by a real 3s
sleep so the proof is expired when the upload completes.
`nostr::Timestamp::now()` reads the OS wall clock directly; paused Tokio
time does not advance it. The negative cases use a pre-expired proof
with a mismatched `x` tag. All four are `#[ignore = "requires MinIO"]`;
no CI lane runs them automatically.

**`buzz-media/src/validation.rs`**
- `minimal_valid_mp4()` promoted to `#[cfg(test)] pub(crate)` — a
618-byte pre-computed H.264/avc1 fast-start MP4 available to all
`buzz-media` test modules; smoke-tested by
`test_minimal_valid_mp4_passes_validate_video_file`.

**`desktop/src-tauri/src/commands/media.rs`**
- `sign_blossom_upload_auth`: `server` tag mandatory; upload expiry 60s
(was 3600s/300s).
- `MEDIA_GET_AUTH_EXPIRY_SECS`: 60s (was 600s).

**`desktop/src-tauri/src/media_proxy.rs`**
- Single re-mint+retry on 401/403 for range requests; non-auth failures
do not retry.

**`crates/buzz-cli/src/client.rs`**
- Read expiry: 60s (was 600s). Upload expiry: 60s. `server` tag
mandatory on upload.

**`crates/buzz-dev-mcp/src/view_image.rs`**
- `MEDIA_GET_AUTH_EXPIRY_SECS`: 60s (was 600s). Test updated.

**`mobile/lib/shared/relay/media_auth.dart`**
- `_mediaGetAuthLifetimeSeconds`: 60 (was 600). Refresh margin updated.

**`mobile/lib/shared/relay/media_upload.dart`**
- `_uploadAuthLifetimeSeconds`: 60 (was 300). `server` tag mandatory.

**`mobile/lib/features/channels/media_viewer_page/video_viewer.dart`**
- **[F2]** Remove Android-specific `VideoPlayerController.networkUrl`
streaming path. `video_player_android` 2.9.5 freezes headers into static
`DefaultHttpDataSource` request properties — a 60s proof minted at
controller creation time becomes stale on seeks. All platforms use the
authenticated local-file download path.
- **[F2 transport]** `unawaited(request.sink.close())` before
`client.send()`. `AbortableStreamedRequest` carries no request body;
without closing the sink, `IOClient.send()` awaits
`stream.pipe(ioRequest)` which blocks until the sink ends — every video
download hung in loading indefinitely on every platform.
- **[F2 pending-ctrl]** `pendingController` ref set before the first
`await (initialize())`, cleared in all exit paths. Effect cleanup
disposes `pendingController.value` so a close-during-init releases the
native player even if the initialized event never arrives.
- **[F2r(a)]** On native init failure (post-create,
pre-initialized-event), the inner catch starts disposal detached via
`unawaited(localController.dispose().catchError(...))` — the
`.catchError` handler absorbs any disposal exception so it does not
reach the test error zone — then rethrows the original load error.
`video_player` 2.11.1 completes the init future with an error without
disposing the native player.
- **[F2r(b)]** Non-2xx error body cancelled via `_cancelVideoResponse()`
(subscribe+cancel) instead of `drain()`. `drain()` waits for the
upstream to close; a stalled server body blocked `initializeVideo`
indefinitely.
- **[F2r(d)]** `unawaited(localController.dispose().catchError(...))` in
the catch — not `await`. Two failure mechanisms exist: (1) when
`createWithOptions()` throws, `_creatingCompleter` is never completed
and `await dispose()` deadlocks at `:682-683`, blocking the outer catch
from setting error state. (2) when `createWithOptions()` succeeds but
initialization fails, `dispose()` runs but its thrown exception becomes
an unhandled async error reaching the test zone. Both are fixed:
`unawaited` lets the outer catch run immediately and set `error.value`;
`.catchError(...)` on the detached disposal future absorbs any disposal
exception.


**`mobile/test/features/channels/media_viewer_page/video_viewer_test.dart`**
- `_FinalizingFakeClient`: calls `request.finalize().drain()` — a test
without the sink fix times out because the drain never completes,
validating the transport contract.
- F2r(a): `forceInitError=true` fake emits `PlatformException` on
subscribe; `disposeCallCount >= 1` verifies disposal even on init
failure.
- F2r(b): `stalledBody` `StreamController` with `onCancel` Completer
(bounded completion signal, not a sleep). Asserts: (1)
`bodyStreamCancelled=true` while body stream is still open (impossible
with `drain()`); (2) error UI visible while body remains open. Restoring
`drain()` breaks both.
- F2r(c): `neverInitialize=true` fake never sends initialized event;
unmount asserts `disposeCallCount >= 1` via `pendingController`.
Distinct from the event-error case.
- F2r(d): `forceCreateError=true` fake throws `PlatformException` from
`createWithOptions()` itself (before any player ID is returned). Asserts
error UI visible within a bounded deadline. With the old `await
dispose()` the outer catch is blocked — `error.value` is never set and
the error UI assertion fails at the deadline; with
`unawaited(dispose())` the error text appears immediately.


**`mobile/test/features/channels/media_viewer_page/video_viewer_transport_test.dart`**
(separate file)
- Real-IO loopback probes using `flutter_test` (not `package:test`) to
avoid `depend_on_referenced_packages` lint. No
`TestWidgetsFlutterBinding` — no HttpClient override interfering with
`dart:io`.
- Probe 1: `HttpServer.bind(loopbackIPv4, 0)` reads the full request
body before replying. Without `sink.close()`, `req.drain()` hangs and
the test times out.
- Probe 2: server signals request arrival via a Completer (not a sleep);
abort fires after confirmed arrival; `client.send()` must throw
`RequestAbortedException` (typed assertion) within a bounded 5s
deadline.

**`scripts/test-video-upload.sh`**
- Proof minted with `+60` expiry and mandatory `server` tag.

**`buzz-test-client/tests/e2e_media*.rs`** +
**`buzz-relay/src/api/media.rs` test fixtures**
- All fixtures updated to 55s expiry + `server` tag.

**`RELEASING.md`**
- New "NIP-FI upload proof freshness (relay floor)" section documenting
that 60s proofs require the first relay release carrying this PR's
post-body hash-only check (the first tag > `v0.2.1` — update once cut)
for reliable large-file uploads. Operators on older self-hosted relays
(≤ `v0.2.1`) must upgrade before receiving these clients.

## Finding 3: 60s upload proofs vs old-relay compatibility

Desktop/CLI/mobile upload proofs are now 60s. Older relays re-run full
expiry verification after the body is transferred. A valid upload whose
body transfer takes >60s will fail on an old relay.

**Resolution (relay floor prerequisite):** `RELEASING.md` requires that
verified supported deployments (relay releases confirmed to carry the
post-body hash-only check, commit `75e9bef748`) be in place before
distributing 60s-proof client builds. Unknown or unverified self-hosted
relay deployments are excluded from distribution until they upgrade.
This makes the verified-deployment status a prerequisite for release
distribution, not a post-distribution advisory. The concrete tag (`>
v0.2.1`) is to be recorded once cut.

## Sequencing note

Builds on #7264 (merged): Blossom strictness is derived from its
`config.nip_fi` mode in this PR, so enabling `BUZZ_NIP_FI_MODE=enforce`
activates the strict verifier with no further wiring.

## GIF compatibility exception

An unauthenticated Off-mode request on a configured tenant with no GIF
provider changes from 404 to 401 (base `gifs.rs:269-275` checked an
unconfigured provider first; the current code authenticates first). All
other Off-mode Blossom responses are byte-identical to pre-NIP-FI
behavior.

4af2324d85 fix(mobile): keep relay sessions stable during push lease updates (#7745)
Enabling push notifications could repeatedly reset the relay session:
reserving a lease generation updates community metadata, which rebuilt
the relay configuration even though the connection identity was
unchanged. This made the avatar and inbox flash and prevented the new
lease from publishing.

Select only the community ID, relay URL, and signing identity as
configuration dependencies. Push bookkeeping keeps the session intact;
real community, URL, and identity changes still notify listeners.

### Validation
The production-provider regression test failed before the fix and passes
afterward; 48 focused mobile tests and static analysis pass.

A personal signed profile build on a physical iPhone published a fresh
lease and received a background notification with the actual message
text. The user confirmed the flashing stopped and tapping the
notification opened the correct community/channel and highlighted the
exact message.

76f7e5ef0c feat(push): make gateway origin configurable (#7261)
Make the push gateway origin configurable across the relay, gateway,
mobile client, and deployment chart.

This is a fresh deployment. The gateway has only run on personal
development infrastructure, and push has no existing enabled users.
Legacy migration, configured-to-unconfigured mobile transitions, and
rolling upgrades from pre-launch gateway binaries are not supported.

Populated pre-launch databases are rejected with an informative error
before migrations run; their data is untouched. Mobile builds may omit
the gateway URL, leaving push unavailable. Once push is enabled,
subsequent builds must retain that configuration.

### Validation

- All applicable CI checks pass at
`5f546cfaf403f0386f146d213adfb4392f4ec29c`, including Rust,
mobile/Swift, desktop/integration, security, image builds, and Helm
checks. An unrelated agent cancellation test passed on retry.
- PostgreSQL CI passed 384 tests, including the production-entry-point
regression for refusing populated pre-launch databases before
migrations, fresh initialization, and subsequent initialized
deployments.
- Focused local validation passed all 10 gateway PostgreSQL tests under
the CI discovery filter and all 3 unconfigured-mobile tests.
Repository-wide PostgreSQL discovery validation and the complete
pre-push hooks passed.
- Physical-device APNs/App Attest behavior and deployment to a live
cluster were not verified in this work.

2f3dd850db fix(relay): reject a frame on its own acknowledgement channel (#6961)
Pinky, an AI agent, updated this description on Wes's behalf after
taking over the startup investigation.

**Category:** fix

**User Impact:** An EVENT refused by WebSocket admission or handler
saturation receives a correlated `OK(event_id, false, reason)` instead
of an uncorrelated NOTICE, so the client can settle that refusal without
waiting for its publish timeout. Rate-limited refusals also arm client
backoff. This fixes a protocol failure mechanism; it does not establish
that every startup send will succeed or that the reported Desktop
startup incident is fully resolved.

**Problem:** Startup opens several live subscriptions and publishes at
once, and the relay's WebSocket admission gate is a fixed 5-second
window (`ws_admission_budget` = `human_ws_events_per_sec * 5`). If that
shared per-principal quota is exhausted, `enforce_ws_admission`
previously rejected an EVENT with a bare `["NOTICE", reason]`. Quota
pressure is a possible trigger, not proof of the original incident's
complete cause.

A NOTICE carries no event id. Both clients settle a pending publish
*only* from an `OK` keyed by event id (desktop `pendingEvents`, mobile
`_pendingEvents`), so nothing settled — and `handle_text_message`
returns early, so no `OK` ever followed either. The send **could not
fail**; it could only time out at `PUBLISH_TIMEOUT_MS` = 25s. That
explains how this rejection mechanism can produce a roughly 25-second
timeout; attributing the original report to it still requires the actual
startup/send workflow.

The handler-semaphore saturation path had the identical defect, and that
one needs no quota burst to fire.

**Solution:** NIP-01 gives each request type its own acknowledgement
channel, and a rejection is only actionable on the same one. Reject a
REQ with `CLOSED`, an EVENT with `OK(id, false, reason)`, and fall back
to `NOTICE` only where no per-request correlation exists. COUNT refusals
now also use `CLOSED(query_id, reason)` per NIP-45, covering both quota
admission and handler saturation (added in
`cd12c93804b87a24b61075dfd171dc471a0a527f`).

Reason strings are unchanged, so the `rate-limited:` prefix and `retry
in {N}s` hint that existing client gates parse keep working (desktop
`parseRateLimitHint`, mobile `RelayRateLimitGate`, buzz-acp
`set_rate_limit_gate`). Only the frame *type* changes, so
`docs/multi-tenant-relay.md` L7 stays satisfied.

Two notes on how this landed, both worth a reviewer's attention:

1. **A survived mutation became a design change.**
`send_admission_result` originally took a `RejectionTarget` parameter,
and reverting the *second* call site (the per-minute message quota)
survived the whole suite — with Redis unreachable the first quota check
short-circuits, so that line is unreachable in test. Rather than test
around it, the parameter is gone: the target is derived from the frame,
so no call site can name the wrong channel.

2. **The relay fix would have caused a client regression on its own.**
Gate arming lived only in the NOTICE branch. Once rejections arrive as
`OK:false`, `handleOk` failed the send without ever backing off — the
client would retry straight into the same quota. Desktop and Mobile now
arm on a `rate-limited:` OK rejection. ACP was subsequently fixed in
`3b06dd32493596ec650f20abf8805791c50fdc24`: it arms the gate and
re-parks only the refused observer frame, preserving other in-flight
frames. Desktop gets `activateRateLimitIfSignalled` as the single owner
of that prefix test, called from both `handleOk` and the NOTICE branch.

<details>
<summary>File changes</summary>

**crates/buzz-relay/src/rejection.rs** (new)
Owns the admission-rejection concern: `RejectionTarget`,
`rejection_target_for`, `request_rejection_message`,
`send_admission_result`, and `enforce_ws_admission`, moved out of
`connection.rs`. Six tests, two of which drive the real
`enforce_ws_admission` against a real `AppState`.

**crates/buzz-relay/src/connection.rs**
Fix the EVENT handler-semaphore rejection to correlate to the event id;
delegate admission to the new module. Add two tests that drive the real
`handle_text_message` with every handler permit held. Down from 1319 to
1116 lines.

**crates/buzz-relay/src/state.rs**
Widen the existing `test_state` helper to `pub(crate)` so the rejection
tests reuse it rather than adding a ninth copy of `AppState`
construction.

**desktop/src/shared/api/relayRateLimitGate.ts**
Add `activateRateLimitIfSignalled` — one owner for the `rate-limited:`
prefix test, since three inbound frame types now carry it.

**desktop/src/shared/api/relayClientSession.ts**
Arm the gate on a rate-limited OK rejection; route the NOTICE branch
through the same helper. Net zero lines, which keeps this
already-oversized file within the differential ratchet.

**desktop/src/shared/api/relayClientPublishRejection.test.mjs** (new)
Four tests against the real `RelayClient`: a rate-limited OK settles the
pending publish and arms the gate; an ordinary rejection does not arm
it; an accepted OK still resolves.

**mobile/lib/shared/relay/relay_session.dart**
Arm the gate in `_handleOk` for a rate-limited rejection.

**mobile/test/shared/relay/relay_session_test.dart**
Two tests driving the real `publish` + `debugHandleMessage` path.

</details>

<details>
<summary>Validation</summary>

**Mutation-tested — 5 mutations, all now killed.** Each production call
site was reverted to the defective behaviour to confirm a test fails.
This caught two false-negative tests:

| # | Mutation | Result |

| 1 | `rejection_target_for`: EVENT → `Connection` | 4 tests fail |
| 2 | EVENT handler-semaphore call site → bare NOTICE | **survived at
first** |
| 3 | per-minute quota call site → `Connection` | **survived**; fixed by
removing the parameter |
| 4 | desktop `handleOk` gate arming removed | 1 test fails |
| 5 | mobile `_handleOk` gate arming removed | 1 test fails |

Mutation 2 is the lesson: my first saturation test called
`request_rejection_message` directly, so reverting the real call site
inside the `match` arm left it green. It now drives
`handle_text_message` itself and dies on that mutation.

- `cargo test -p buzz-relay` — 928 passed, 1 failed:
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`,
**pre-existing**, reproduced with all changes stashed at `4dd4d73de`.
- `cd desktop && npm test` — 5721 passed, 0 failed (full suite).
- `cd mobile && flutter test` — 1876 passed, 0 failed (full suite).
- `just fmt-check`, `just clippy`, `just desktop-check`, `just
mobile-check`, `just file-size-check` — clean. Desktop's 5 biome
warnings are pre-existing (reproduced with changes stashed).
- All 9 pre-push lanes green, including `rust-tests` and
`desktop-tauri-checks`.

**Not verified:** not reproduced end-to-end against a live relay under a
forced quota burst. The causal chain is source-proven and
mutation-proven at the frame level; the ~25s attribution follows from
`PUBLISH_TIMEOUT_MS` but is not directly measured. A packaged-build
click-through would close that gap.

</details>

Related work: #6957 bounds Desktop HTTP event submission, but safe
retained-operation recovery after exhausted/ambiguous outcomes remains
unfinished. #6998 is the separately reviewable Desktop
readiness/duplicate-subscription slice. Neither is claimed to complete
native before/after startup-send validation.

## Current review disposition (2026-08-28)

The [review on
`cd12c938`](https://github.com/block/buzz/pull/6961#pullrequestreview-5052902510)
identified ACP's missing rate-limited-OK handling. Commit
`3b06dd32493596ec650f20abf8805791c50fdc24` fixes gate arming, re-parking
the specifically refused observer frame, and the stale NOTICE comment.
Two regressions drive the real frame dispatcher. See [the implementation
and validation
response](https://github.com/block/buzz/pull/6961#issuecomment-5455032054).

The Mobile generation-check inline thread is resolved: its `async
publish` returns a failed Future when superseded; it does not throw
synchronously at invocation. No further production change was indicated
by that comment.

The validation counts above describe the original slice, not a new
rerun. At `3b06dd324`, the current GitHub check rollup has successful
completed test/build checks (non-applicable jobs skipped). The
security-review comment still requires review for the current base/head
range; do not read a green authorization job as a completed security
review. Approval and merge remain human decisions.

b593c7d7fe perf(mobile): reduce cold startup and channel rendering delays (#6996)
Pinky is opening this PR on Wes’s behalf.

## Summary

Reduce two separately measured mobile delays without changing the relay
API or removing rich message rendering:

- Publish the finite channel-list snapshot without waiting for live
subscription setup.
- Batch active channel-list subscriptions into sorted, deterministic
chunks of at most 128 explicit channel IDs, retaining unchanged chunks.
- Install replacement chunks before retiring old coverage. Retain old
chunks across thrown replacement failures; filter callbacks to the
current relay/identity and still-desired channels; clean up
retired/in-flight work across disconnect and disposal.
- Scope the custom-emoji Markdown matcher to known shortcodes actually
referenced in the rendered content, rather than embedding the whole
community palette in every message’s regex. Preserve unknown literals,
shared-colon token boundaries, event-tag URL priority, content edits,
and code literals.
- Honor explicit zero retry hints without inventing a ten-second
session-wide gate, while preserving the ordinary live-subscription retry
backoff and any already-active gate.

## Matched performance results

Medians of three before and three after process-cold launches,
alternated on the same authenticated iPhone 17 Pro / iOS 26.5 simulator.
Before is mobile source at `e76c81968b65b0755b83efdd59dc3375c59ddf40`;
after is this production patch before two documentation-only comment
fixes.

First channel-list frame: 11.617s → 3.179s · 73% lower latency

Live setup duration: 8.475s → 0.185s · 98% lower latency

Channel-open first message-list frame: 2.754s → 1.230s · 55% lower
latency

Message data ready → first frame: 1.977s → 0.286s · 86% lower latency

Channel-open reveal complete: 2.845s → 1.394s · 51% lower latency

Channel-open data readiness: 0.770s → 0.944s · 23% higher latency

The gain is client-side orchestration/rendering, not a claim that the
relay became faster. First channel-list frame ranges were 10.835–11.788s
before and 2.872–3.395s after; channel-open first-frame ranges were
1.560–2.906s before and 1.149–1.317s after.

### Measurement boundaries

- Debug simulator builds, CPU sampling disabled, bounded timestamp
probes enabled identically. These are not release/physical-device
measurements.
- Startup clock starts at Dart `main`; build/install/native pre-main
time is excluded. Auth/preferences and OS/disk caches are retained
between new processes.
- Same account scale: 113 active channels. Latest-message events varied
slightly with live activity (1543–1546).
- Channel-open uses the same initial 50-row history window, 97 query
events, and 67 provider events. The 2306-entry emoji palette is
explicitly loaded before navigation on both sides; palette preparation
is excluded from the channel-open clock and happens after the startup
frame measurement.
- Both diagnostic builds temporarily disabled unused avatar segmentation
to work around the existing Google ML Kit arm64-simulator slice
limitation. The workaround, dependency/native changes, auto-navigation,
and all probes are excluded from this PR.

## Validation

- Full mobile package suite: `flutter test` — 1890 passed.
- `just mobile-check` — 506 files unchanged; analyzer clean.
- `just file-size-check` — policy tests and all client ratchets passed.
- `git diff --check` — passed.
- New lifecycle regressions cover front-sorting insertion across a chunk
boundary while replacement readiness is paused, failure
retention/departed-channel filtering, retired generation + disconnect
cleanup, disposal, chunk limits, unchanged-set reuse, and scope
switches.
- Emoji unit/widget coverage includes a 2500-unused-emoji palette,
unknown tokens, case matching at the component level, shared-colon
boundaries, rich text, event URL priority, and content edits.
- Fresh-frame source review traced the subscription queue/fences,
callback scopes, duplicate-event paths, matcher/wiring, and retry
scheduling.
- At committed/pushed head `13a83b628c8411c5885e6f76a250ba87accf6067`,
all normal pre-push hooks passed: `mobile-checks` (formatter, analyzer,
and the full 1890-test mobile suite), `file-size-check`, `branch-skew`,
and `push-head-scope`. The commit hook formatted 506 files with no
changes. Runtime measurements preceded only the two
documentation-comment fixes; no runtime source changed afterward.

## Limits / follow-ups

- `RelaySession.subscribe` still settles under its existing
EOSE/fallback/retryable-CLOSED contract. “Setup completed” is not an
unconditional EOSE or live-delivery guarantee. This PR does not add
status-aware replacement ownership.
- The channel-message provider still awaits subscribe before fetching
history; that separate serialization is not removed here.
- Oversized Huddle queries and the separate history batching path above
128 active channels remain follow-ups, as do pre-existing read-state
initialization/size warnings.
- Palette-only widget refresh and upstream Markdown uppercase-dispatch
behavior are not changed.
- A clean source build still has the existing Google ML Kit
arm64-simulator issue; the profiling workaround is not a proposed
product fix.

c432a111ca feat(mobile): push notifications MVP (#6269)
This PR implements MVP, iOS-only,
[NIP-PL](8d2d0ff5ad/docs/nips/NIP-PL.md)-compliant
push notifications.

A relay with `BUZZ_PUSH_ENABLED` will send a push notification for any
message that appears in the in-app Notifications tab.

## Enrollment flow
The first time the client first connects to a relay with
`BUZZ_PUSH_ENABLED`:

    NSE->>iOS: Complete notification: title, body, subtitle<br/>thread ID, exact-message target
```

relay → push gateway → APNs -> NSE -> Notification Center

## Known limitations

The APNs wake payload is intentionally constant and opaque: it contains
no originating community or message identifier, in keeping with the
implemented NIP-PL privacy design.

The Notification Service Extension must therefore reconnect to the relay
and resolve eligible messages after each wake. Around overlapping wakes,
timing boundaries, or resolution windows, notification presentation may
occasionally omit an expected message or display a message more than
once.

This best-effort behavior is deliberately accepted for the current
implementation and will be measured during the internal rollout to
determine whether the user experience is acceptable before any broader
deployment; the implementation does not claim exactly-once presentation.

## Validation

Live end-to-end hardware validation used an internal remotely hosted
development relay and push gateway, the APNs sandbox, and a physical
iPhone 12 mini:

- A second real Buzz client published a uniquely marked message through
the hosted relay.
- The relay matched the message and sent the constant opaque wake
through the hosted gateway. The gateway made an actual APNs request; no
`simctl push` or simulated notification was used.
- The iPhone received the notification on its lock screen. The
Notification Service Extension reconnected to the relay, fetched the
event, verified its ID and signature, and replaced the placeholder
content with the real notification title and body.
- After the app populated its shared presentation cache, a final marked
notification visibly showed the sender display name, sender avatar, and
hashtag-prefixed channel name.
- Tapping a lock-screen notification opened Buzz and exercised the
notification-response path and navigated to the corresponding message.

Final validation with a dogfood-signed artifact and production App
Attest/APNs configuration remains a release step.

4d77175c78 fix(client): resurface hidden DMs from live activity (#6885)
## Summary

Hiding a DM row and then receiving a new message from that person never
brought the row back — the reader was left with only an Inbox
notification. This restores the row from live activity, client-side,
with no relay or database changes.

- Subscribe to hidden-DM activity **channel-scoped** over the hidden-DM
id set (`#h`), re-registering whenever the set changes. The relay's
`fan_out_scoped` only routes channel-scoped events (every kind:9 DM
carries a `channel_id`) to channel-scoped subscriptions, so a
community-global `#p` filter receives nothing. Hiding a DM never drops
membership, so `#h` authorization holds. Because every delivered event
is already for a hidden DM the reader belongs to, eligibility no longer
needs a self `p` tag — untagged CLI/agent DMs resurface too — and no
per-event visibility fetch is required.
- On qualifying activity, invoke the existing open-DM action (`41010`)
to reopen the hidden one-to-one or group DM, validating that the relay
reopened the same channel.
- Preserve the existing relay-synced hide snapshot (`41012` → `30622`);
hide state still syncs across devices.
- Let Inbox reopen a hidden DM before navigating to its message, with a
busy state on the row and context-menu "Open in channel" action while a
reopen is pending.
- Coalesce resurface attempts per channel: a concurrent message that
arrives while a reopen is in flight triggers a retry on failure instead
of being marked handled and dropped.
- Write exact dm-visibility query keys on open/hide mutations.

This is the client-only replacement agreed in the Buzz design thread and
supersedes #6713. The accepted limitation is that resurface only fires
while a client is running — a message that arrives while all clients are
closed does not restore the row on next launch (the `30622` snapshot has
no watermark); Inbox click-through is the safety net for that case.

Addresses #6316.

ce56e34411 fix(mobile): recover stale relay sessions (#4372)
### 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.

a5dbdf5e61 fix(mobile): recover and pace live subscriptions (#3053)
### 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.

85edc0572a feat(mobile): desktop-parity emoji and thread experience (#3485)
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.

047533c56c fix(mobile): keep TLS on relays joined by invite (#3139)
## 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.

### Related issue

Fixes #2662.

### 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.

68f39f3697 feat(mobile): bring message actions to desktop parity (#3070)
**Category:** new-feature
**User Impact:** Mobile users can copy permalinks, revisit, follow, and
manage messages through a clearer long-press menu that matches desktop
capabilities.

**Problem:** The mobile message menu exposed only a small subset of
desktop actions, and important workflows such as copying a permalink or
scheduling a reminder were unavailable or hard to discover.

**Solution:** Bring applicable desktop actions to mobile using native
patterns, promote Reply, Copy link, and Remind me above the fold, and
group the remaining actions by intent in a scrollable sheet.

**Intentional behavior changes (per review):**
- The quick-reaction row goes from 6 emojis to 4 (👀 and 🙏 dropped) to
make room for larger 52px tap targets alongside the `+` picker, which
still offers the full set.
- **Copy link — not a native share sheet — is the permalink path.** An
earlier revision shipped a `share_plus` Share message row; it was
removed in review since Copy link covers the job and custom-scheme
`buzz://` URIs are handled inconsistently by share targets. Native share
can return as a follow-up with an https fallback.
- Mark unread is message-scoped and session-local: it forces just that
message unread (surfacing its channel as unread), and message-level Mark
read can never clear a channel-level unread set from the channel tile.

<details>
<summary>File changes</summary>

**mobile/lib/features/channels/channels_provider.dart**
Feeds followed thread roots into unread and notification evaluation so
following a thread has meaningful behavior.

**mobile/lib/features/channels/message_actions.dart**
Reworks the long-press sheet with promoted fast actions, message links,
reminders, read state, thread following, and clearer action grouping
while preserving existing guards. Quick-reaction circles share one
extracted widget.

**mobile/lib/features/channels/read_state/message_read_state.dart**
Centralizes message-level unread evaluation across channel, message, and
thread markers; channel-level forced unread deliberately does not leak
into message state.

**mobile/lib/features/channels/read_state/read_state_provider.dart**
Forced-unread flags are per-context (channel id or `msg:` key) mapped to
their channel, so message- and channel-level unread choices round-trip
independently.


**mobile/lib/features/channels/thread_follows/thread_follows_provider.dart**
Exposes per-identity thread follow state to the message menu and
notification pipeline.


**mobile/lib/features/channels/thread_follows/thread_follows_storage.dart**
Persists a bounded, validated set of followed thread roots on the
device.

**mobile/lib/shared/reminders/remind_me_later_sheet.dart**
Adds reminder presets and a native custom date/time flow for deferring a
message. Lives under `shared/` so the channels feature never imports
another feature module. Cancelling the custom picker keeps the preset
sheet open; submission failures show stable copy and log the underlying
error.

**mobile/lib/shared/reminders/reminder_service.dart**

**mobile/test/features/channels/message_actions_test.dart**
Covers action visibility and guards, promoted actions, read/unread
round-tripping (including channel- vs message-level force isolation),
thread follows, and canonical links.


**mobile/test/features/channels/read_state/message_read_state_test.dart**
Covers unread precedence for channel, message, and thread contexts.


**mobile/test/features/channels/thread_follows/thread_follows_storage_test.dart**

bounds.

**mobile/test/shared/reminders/reminder_service_test.dart**
Covers reminder payloads, tags, crypto round-tripping, and preset
behavior.


**mobile/test/features/channels/read_state/read_state_provider_test.dart**
Drives the production ReadStateNotifier/ReadStateManager (no fake
bookkeeping) through message unread → read → unread round-trips,
explicit channel-level Mark read clearing forced messages, and automatic
channel-open reads preserving them.

**mobile/test/shared/reminders/remind_me_later_sheet_test.dart**
Covers custom-picker cancel keeping the sheet open, stable failure copy
without the raw error, and the happy preset path.

**mobile/test/shared/deeplink/deep_link_test.dart**
Covers canonical top-level and threaded message-link generation.

## Reproduction steps

1. Run the mobile app with a signed-in identity and open a channel
containing regular messages and threads.
2. Long-press a message and confirm reactions plus Reply, Copy link, and
Remind me appear as fast actions above the fold.
3. Use Copy link; confirm the resulting `buzz://message` link opens the
correct channel and thread context.
4. Toggle Mark unread/Mark read and Follow thread/Unfollow thread,
reopening the sheet to confirm each state changes correctly. Force a
channel unread from the channel tile, then mark a message read — the
channel stays unread.
5. Choose a reminder preset and a custom date/time; confirm the reminder
is created and appears in the desktop reminder experience. Cancel the
custom date picker and confirm the reminder sheet stays open.
6. Long-press a system message and a message you cannot manage; confirm
utility and destructive actions remain appropriately hidden.

3742076434 fix(mobile): mitigate message-post delay with optimistic rendering (#3037)
### What changed?

Adds optimistic rendering for newly locally posted messages in channels
and threads.
- Messages appear immediately
- Relay echoes and history are deduplicated by event ID
- Rejected or timed-out publishes erase the optimistic rendering.

The implementation covers reconnect and hydration races, channel-window
and legacy WebSocket paths, thread-local overlays, and rapid concurrent
sends.

### Why?

This is a valuable partial mitigation for
[BOT-1449](https://linear.app/squareup/issue/BOT-1449/buzz-mobile-posted-messages-dont-appear-until-leavingre-entering-the):
senders no longer depend on receiving a relay echo before seeing their
own post.

It does not address the likely primary cause of stale channels. Mobile
currently does not recover live subscriptions after a rate-limited relay
`CLOSED`; that recovery is being handled separately.

### How is it tested?

Full mobile suite: 676 passed, 1 skipped.

Added regression coverage for optimistic insertion, authoritative
deduplication, rollback, reconnect and hydration, thread replies, rapid
and equal-time sends, never-echoed successful sends, and legacy
WebSocket retirement.

c9a73726be fix(mobile): validate invite relay destinations (#2986)
## 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.
