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

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

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

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

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

8f2c7710e9 fix(mobile): default community push notifications to on (#8425)
New mobile communities currently require a manual Settings opt-in before
push can start. Default that local preference to on for new communities
and stored records without a preference. Preserve every saved `true` or
`false`, including values written by older clients. Older default-off
values are indistinguishable from explicit opt-outs, so this does not
migrate them to on.

Push still requires a configured gateway, authenticated connectivity,
and a valid relay capability. iOS continues to control display
authorization through its existing permission prompt. Notification
eligibility and subscriptions are unchanged. Settings retains its
existing opt-out control for enabled communities even when capability is
unavailable.

Drafted from the 0.24 baseline; release-branch inclusion is a separate
decision.

### Related issue

Closest related issue: #3238 (synced defaults). This change is limited
to the mobile device-local community preference; no duplicate found.

### Validation

- Added or updated coverage for new and missing preferences, saved
true/false persistence, opt-out after restart, capability-gated
registration, and Settings without a configured gateway.
- Full configured mobile suite: 3,499 passed, 4 skipped. Separate
no-gateway suite: 4 passed. Flutter analysis passed.
- Existing permission-denied and unsupported-relay tests passed as part
of the mobile suite. No physical-device or end-to-end APNs validation
performed.
- Full local repository gate passed (formatting, lint, unit tests,
desktop/web builds, Tauri checks/tests, and mobile tests).



- Follow-up review edits: restored the original VISION.md wording and
shared the default in one private Community constant. All 43 focused
community/bootstrap tests passed.

c09730e874 fix(mobile): keep notification toggle usable and match row height (#8223)
Turning Notifications off invalidated the relay capability provider
because it watched the entire saved community. If the redundant NIP-11
request stalled or failed, the switch became disabled and reopening
Settings did not recover it. Discovery now follows community identity
and connection status, so preference and lease bookkeeping retain the
validated capability while a real reconnect still refreshes it. Each
opt-in also starts a fresh active lease immediately instead of waiting
for the old renewal timer. Failed attempts retain their gate until the
retry delay expires, preventing rebuilds from bypassing backoff.

Notifications now has the same single-line height as Set status, with
the full switch hit area and one combined accessibility label. This
follows [#8201](https://github.com/block/buzz/pull/8201); no duplicate
open PR was found.

### Validation

Added iOS widget regressions mount the production settings page and push
bootstrap with production storage logic, signing, and lease publication.
They verify a higher-generation active replacement after off/on with
accepted, failed, and pending cleanup, plus closing/reopening Settings,
switch and row taps, 2× text, accessibility, and rediscovery on
reconnect. A gate test verifies that rebuilds cannot bypass failure
backoff. Both UI failures and the missing active replacement were
reproduced before their fixes.

Mobile dependency installation, formatting/static checks, 3,234
configured tests, and three unconfigured-build tests passed. Captures
use the real Flutter settings widget at 375pt width, with synthetic data
and mocked native/network boundaries. Native navigation is outside the
capture. No device installation or deployment was performed.

After merge, validate the candidate on iOS: compare Notifications with
Set status, toggle off then immediately on, close/reopen Settings while
off and turn on, and repeat after reconnect. Confirm delivery resumes
after opt-in.

### Layout

Flutter widget captures with synthetic data; native navigation is
excluded.

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.

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.
