Tom Brow	fea02d174d	fix(ios): fetch profiles and avatars in notification extension (#8369) ... A notification can arrive from someone whose profile the main app has never loaded. The iOS notification extension now fetches and caches sender profiles, channel details, and avatars itself. The main app supplies account configuration and Keychain credentials only. After resolving the message, the extension allows 1.5 seconds for sender and channel details. It uses available stale data when a refresh is slow or fails, delivers once, and lets late results update its private cache. Profiles, channel details, and avatar refresh checks share a one-hour freshness threshold. A verified avatar removal clears the previous image. Account removal prevents further use of that sign-in's cached data. Profile, channel metadata, and membership use separate bounded downloads, so an oversized roster cannot discard the smaller records. Sender enrichment can finish while channel requests are pending. A successful partial channel refresh atomically removes its old counterpart, preventing a mixed group identity or recipient count. Group-specific notification presentation still requires a verified recipient count. The [specification](https://github.com/block/buzz/blob/native-notification-enrichment/docs/native-notification-enrichment.md) describes the display, caching, and account-removal behavior. General persistent image caching in Flutter remains separate. ### Validation [Hosted CI](https://github.com/block/buzz/actions/runs/38780108487) passed on the final commit, including all Flutter shards, Android, the full iOS release and simulator builds, and native controls/push-navigation tests. The [current-commit security review](https://github.com/block/buzz/pull/8369#issuecomment-6197508385) found no issues. The native package passed 159 tests, including new coverage for cache freshness, avatar replacement and removal, sign-in isolation, concurrent storage, late results, single delivery, bounded downloads, and SVG validation. A regression test exposed identical HTTP authentication event IDs for requests in the same second; each request now includes a unique nonce, matching the Dart and CLI clients. Full local CI passed before that small authentication fix. The complete native suite and signed device build passed again on the latest commit, including response-size limits, overlapping avatar downloads, canonical relay-origin matching, independent profile/channel refreshes, account-key changes before and during requests, and a single initial snapshot read across 64 accounts, signed IPv6 avatar authorities, and partial channel refreshes. Focused Flutter regression tests passed 198 tests with three configuration-specific skips; seven avatar widget tests also passed. Flutter analysis is clean, and the notification extension builds for the simulator. On an iPhone SE, the notification displayed the sender name, avatar, channel, and message before the updated main app was opened. Repeat notifications used a byte-identical private cache. Three notifications delivered together displayed the avatar after the authentication fix. The next notification also displayed correctly after terminating the extension process. The existing generic-push design can select the same newest unread message for several pushes; this change does not alter message selection.  Authenticated HTTP avatar fetching and persistent HTTP cache reuse also passed on the SE. The first notification downloaded a relay thumbnail. After terminating the extension and expiring its separate avatar entry, the next notification displayed the avatar and refreshed that entry without another media request in the relay logs. The main app remained unopened throughout. The original app build and test profile were restored afterward. Automated tests cover slow and failed requests, stale images, removal, and account revocation; those cases have not all been exercised on the phone. ### Before merge - [x] Verify authenticated HTTP avatar fetching and cache reuse on iOS against a working relay media service. <!-- buzz-review-completed --> --------- Signed-off-by: Tom Brow <tomb@block.xyz>	2026-10-15 11:16:04 -07:00
Tom Brow	b8aa0233f9	perf(mobile): verify notification cache events in background (#7650) ... On iOS, Buzz stores verified profile and channel information for the notification extension. The extension uses this cache to show sender and channel names. Loading profiles or channels also updates the cache. Cache updates currently check event signatures on the UI thread, even when the caller does not wait for the update. This can delay taps and screen updates. This change moves those checks to a background worker. Signature checks, event selection, community boundaries, and the order of native writes are preserved. The worker accepts up to eight batches. When it is busy, later profile requests stay coalesced before fetching; profiles already loaded remain available immediately. Overlapping channel updates trigger a fresh joined-channel cache snapshot after the current export finishes, without delaying or restarting the channel screen. Queue saturation gets up to five retries per operation. Pending updates get their own recovery attempt even if the preceding export fails. Recovery fetches joined-channel data once and retries cache admission without repeating relay reads. It does not fetch the open-channel directory. Verified payloads are split into native-sized writes (256 profiles or 512 paired channels), keeping the same export ordering. Native profile/channel write failures retry the same verified chunk while retaining the export's queue position. All chunks share five retries with 7.75 seconds total backoff; other native errors fail immediately. Terminal failures are recorded, and later successful writes do not hide them. Captured batches keep their original community. Pending channel refetches are retired on a community switch and refreshed when the user returns. The cache remains best effort; prolonged failures can still prevent delivery. Tests through the production APIs reduced UI delay from 27–31 ms to below 0.3 ms for four profiles, and from 59–60 ms to below 0.3 ms for four channel and membership pairs. The native payloads were identical. This does not measure overall screen speed. Validation: 2,225 mobile tests passed (one skipped), along with 18 focused export tests, 12 recovery tests, 39 native Swift tests, 35 focused profile tests, and static analysis. Production regressions cover 13-entity bursts, invalid newer events, community rebuilds, reentrant refreshes, and terminal failures. Regression tests fail when producer recovery controls, terminal-failure draining, or member-only recovery scope are removed. --------- Signed-off-by: Tom Brow <tomb@block.xyz>	2026-09-15 23:01:46 +00:00
Tom Brow	41c5ace937	perf(mobile): move profile sig checks off main thread (#7648) ... The mobile app loads user profiles to show names, avatars, and agent ownership. Some profiles include a signature that proves who owns the agent. Checking these signatures for a batch of profiles can block interaction because the checks run on the same thread that draws the screen and handles input. This change moves profile batch parsing and signature checks to a background worker. It processes one batch at a time and combines queued profile requests. It keeps the same signature checks, preserves newer profiles that arrive while a batch runs, and discards results after a community change. Individual live profile updates still use synchronous verification. Tests cover newer live updates, community changes, overlapping requests, stale malformed events, and UI timer responsiveness through the production parser. The responsiveness test fails if parsing is moved back to the UI isolate. A regression also exercises a confirmed profile save while an older batch is paused, including preservation of verified ownership. All 38 focused tests, all 2,132 mobile tests, and the analyzer pass. With 500 valid owner signatures, an AOT test reduced the main-isolate timer delay from about 3.4 seconds to less than a millisecond. Total verification time stayed similar. This measures verification work, not overall screen speed. GitHub CI passes. The full local test run failed on two timing-sensitive ACP tests in unchanged Rust code; both passed isolated retries. All other local checks passed, including the downstream tests and builds run after that failure. --------- Signed-off-by: Tom Brow <tomb@block.xyz>	2026-09-15 20:00:37 +00:00
Tom Brow	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`: ```mermaid sequenceDiagram autonumber participant App as Buzz iOS app participant iOS participant Relay as Buzz relay participant Attest as Apple App Attest participant Gateway as Push gateway App->>Relay: Fetch NIP-11 push capability Relay-->>App: Push profile, current relay public key, and limits par App->>iOS: Request notification permission iOS-->>App: Permission result and App->>iOS: Register for remote notifications iOS-->>App: Device token end App->>Gateway: Request installation challenge Gateway-->>App: Single-use challenge App->>Attest: Attest installation transcript Attest-->>App: Attestation proof App->>Gateway: Enroll device token and proof Gateway-->>App: Installation handle App->>Gateway: Request delegation challenge Gateway-->>App: Single-use challenge App->>Attest: Assert relay-key delegation Attest-->>App: Assertion App->>Gateway: Create delegation Gateway-->>App: Opaque endpoint grant App->>Relay: Publish encrypted push lease and filters Relay-->>App: Lease acknowledged ``` ## Push-time flow When a notification-eligible event is received by the relay: ```mermaid %%{init: { "sequence": { "actorMargin": 20, "width": 110, "messageMargin": 18, "diagramMarginX": 8, "wrap": true } }}%% sequenceDiagram autonumber participant Relay as Buzz relay participant Gateway as Push gateway participant APNs as Apple Push<br/>Notification service participant iOS participant NSE as Notification service<br/>extension Relay->>Gateway: POST /v1/deliveries/apns<br/>opaque endpoint grant, request ID, expiry, NIP-98 authorization Gateway->>APNs: POST /3/device/{device-token}<br/>topic, request ID, expiry, constant mutable-content payload APNs-->>Gateway: 200 OK: request accepted Gateway-->>Relay: 200 OK: accepted status APNs-->>iOS: Notification: constant reconnect alert<br/>mutable-content = 1 iOS->>NSE: Invoke extension<br/>original notification content NSE->>Relay: POST /query: subscription filters, limit 10<br/>NIP-98 authorization Relay-->>NSE: 200 OK: signed Nostr events<br/>kinds 9, 40002, 45001, or 45003 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. ## Independent pre-reviews - **First pass:** [Carl](buzz://message?channel=18882f4c-289f-41db-942f-81f6f8066da1&id=74ab9a93bb227f3e762568f1cf9fee66d7495b0edc3918735ff787238b9cc585) found missing transient retries, executor-key rotation suppression, duplicate installation renewal, and an unauthenticated challenge write amplifier.
