Tom Brow	cec918ae7a	perf(mobile): show a static placeholder for posterless videos (#9138) ... Video messages without a NIP-71 poster (older events, or uploads where poster generation failed) used to start a network `VideoPlayerController` for each bubble, seek to 100 ms and show that paused frame. Nothing cached the frame, and the decoder was disposed whenever the bubble left the tree, so every scroll back opened a new stream and decoded again. Those bubbles now show the existing static "Video attachment" placeholder with the play button. Nothing loads until the user taps, and the full-screen viewer behaves as before. Videos that have a poster are unchanged. ### Validation - Full mobile Flutter test suite passes, and `flutter analyze` is clean. - The change is almost pure deletion: the frame loader, its provider and test seam, and the tests that covered it are removed. - Limitation: no simulator run. A cloned golden sim built from this branch signed in to the internal community, but its channel list never finished loading, so I couldn't open a channel with a posterless video. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com>	2026-11-05 14:36:05 -08:00
Tom Brow	1b9b307176	fix(mobile): renew expired assertions for native media and drop retired-session avatars (#9134) ... Follow-up to [#9069 media auth](https://github.com/block/buzz/pull/9069), which merged at its approved head. This PR carries the fixes for the last review round on that PR. ### Changes - **Native media reads renew an expired assertion** (Carl's [recommended blocker](https://github.com/block/buzz/pull/9069#discussion_r4485183400)). Voice notes and posterless video previews hand headers to native code. They now use `freshNativeMediaHeadersProvider`, which awaits `HostedRelayAuth.headersForUrl` and so asks for a new assertion once the cached one has expired. Before, while the socket stayed up they sent none and the relay refused the read. If the renewal fails, the read falls back to cached headers and the relay decides. The voice-note player's `headers` callback is now `FutureOr`. Both the iOS authenticated download and the Android native load await it, then recheck their generation, so a cancel during a slow renewal never starts the stale load. - **Notification avatars drop a retired organization session** ([review thread](https://github.com/block/buzz/pull/9069#discussion_r4485125609)). When an avatar download finishes after the organization session that issued its assertion was replaced, BuzzPushKit removes the cached response and refuses the avatar. - **Test:** cached reads never present a signed-out or replaced account's assertion ([optional note](https://github.com/block/buzz/pull/9069#discussion_r4485183412)). Not changed: native reaction-detail avatars still use the cached assertion. After it expires they fall back to initials. ### Validation - Each new test was checked to fail with the code it guards reverted: - `replacedOrganizationSessionRefusesAvatar` (BuzzPushKit): a session replaced mid-download must be refused. - `fresh native media headers renew an expired assertion`: covers renewal and the fallback when renewal fails. - `remote voice notes renew an expired relay assertion`: a journey through `VoiceNoteAttachment`; it fails when the attachment is switched back to the synchronous provider. - `Android defers remote auth until playback starts`: now cancels during a slow renewal and expects no native load. - `an issued assertion serves cached reads for the relay`: now signs out and restores a replacement account. It fails without the account check. - `swift test` (69 tests) passes. The full mobile suite (`just mobile-install mobile-check mobile-test`) passes with these commits on main as of [#9069 media auth](https://github.com/block/buzz/pull/9069). - The automated full-app simulator run from [#9069 media auth](https://github.com/block/buzz/pull/9069) covers the surrounding flows. This change is limited to the header source for voice notes and video previews, and none of the test communities enforce the hosted assertion, so a simulator run would not show the difference. No end-to-end run against a relay that enforces the assertion. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 13:44:54 -08:00
Tom Brow	97ede701c0	fix(mobile): send hosted relay assertion from native media and tombstone paths (#9069) ... Follow-up to https://github.com/block/buzz/pull/9056, from an audit for other places that miss the hosted relay assertion. Hosted and organization relays require `Nostr-Federated-Identity` on every non-exempt HTTP request and WebSocket upgrade. The Dart `HostedRelayHttpClient` adds it, but anything that downloads or connects outside that client has to add it itself. The notification service extension and the iOS emoji picker both missed it, and these places do too: - **Voice notes** (`just_audio`, mainly Android) and **video preview first frames** fetch media natively with only the Blossom `Authorization` header. Both now use `nativeMediaHeadersProvider` from https://github.com/block/buzz/pull/9056. - **Push-lease tombstones**: removing a community, and the durable revocation outbox, open a one-off relay socket with no headers. A hosted relay refuses the upgrade, so the lease is never revoked and the outbox keeps retrying. Both now ask `HostedRelayAuth` for that community's own assertion, because the community being removed may not be the active session. - **Notification avatars** (iOS notification service extension): relay-hosted sender avatars were fetched with Blossom auth only. The loader now takes the same `BuzzRelayAssertionIssuer` the resolver uses for `/query`. Signed requests already refuse redirects. The iOS Me-chat agent picker also fetched avatars with no headers, but https://github.com/block/buzz/pull/9079 removed that native screen, so this PR no longer touches it. ### Validation - Added tests, each checked to fail when the code it guards is reverted: - A queued push-lease revocation and a community-removal tombstone both send `Nostr-Federated-Identity` on the WebSocket upgrade, as background requests. Runs against a local relay socket that handles NIP-42 auth. - A notification avatar on an organization relay is downloaded with the issued assertion (BuzzPushKit). - Issuing for a second community keeps the first one's cached assertion. A background request records no failure, never backs up the key, and its failure never reaches the active community's reconnect waiting on it. - Background issuance never binds an unbound account to its key, bypasses the shared assertion cache (each attempt gets a fresh assertion, and foreground use never inherits one that skipped the key backup), and its failure is never handed to a foreground caller waiting on it. When it can't get an assertion it sends none, so a non-enforcing relay still accepts the tombstone. - A notification avatar whose organization session is replaced mid-download is refused and dropped from the cache (BuzzPushKit). - Voice notes and posterless video previews renew an expired assertion before the native fetch, and fall back to cached headers if renewal fails. A voice-note attachment journey binds the production provider. - Cached reads never present a signed-out or replaced account's assertion. - `flutter analyze` is clean. `swift test` passes for the BuzzPushKit avatar loader tests, and `flutter build ios --simulator --debug` succeeds. - Full mobile suite (`just mobile-check` and `just mobile-test`) passes at 2c84940832. - Automated full-app run on an iOS simulator (debug build of this PR before it was rebuilt on main, signed in to the internal Builderlab community with two more communities saved). Passed: launch and channel list, image attachments and avatars in a channel, New chat sheet kept open for about 80 seconds before the agent list was opened (all agent avatars loaded, so headers are requested per download), dismiss and reopen, background and resume, switching to a second community (its icon and avatars loaded), and removing a community. The native New chat sheet is unreachable in the normal flow on this branch (a new chat opens the Flutter draft page; the native sheet only opens when resuming an unfinished chat), so that check ran with a temporary local bypass that was reverted. Limits: none of these communities requires the hosted relay assertion in this build, so the run shows the Swift-to-Dart header bridge, the per-relay cache and the tombstone path cause no regression, not that the assertion is sent or accepted. No voice note, video preview or deleted message was reachable. Screenshots are omitted because they show internal channel content. - Limitations: no end-to-end run against a hosted relay. Simulator sign-in to a hosted relay needs SSO, so a hosted-relay run needs a device build. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-05 12:32:18 -08:00
Tom Brow	6793cbd25b	fix(mobile): focus the search field when search opens (#9120) ... Opening search from Home now focuses the search field, so the keyboard comes up right away and you can start typing without tapping the field first. This applies when `SearchPage` opens as its own route; the embedded variant is unchanged. Closing with X and reopening works as before (the previous query is kept and the field is focused again). ### Validation - Extended the existing open-and-close journey in `search_page_test.dart`: it now opens search without tapping the field and asserts the field has focus and the keyboard is shown. The step fails with the production change reverted. - Full mobile test suite and checks passed in the pre-push hook. - Automated run on an iOS 27 simulator (iPhone 17 Pro) signed in to a real community: opened search from Home (keyboard up, caret in the field), typed a query and got channel and message results, closed with X, reopened (keyboard up again). The recording contains internal community content, so it was shared internally rather than here. - Human testing waived under the author's standing exception; the automated simulator run above covers it. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 11:49:48 -08:00
John Matthew Tennant	c848b6dcad	fix(mobile): offer a new identity beside saved keys on unclaimed accounts (#9107) ... ## Summary This fixes a dead end in mobile Builderlab sign-in. A new account (unbound, with no backups) on a device that already had saved identities could only pick one of those identities. Any saved key forced the picker, and creating a key required the device to have none. If the service then definitively rejected binding the chosen key, the app showed "Let's try that again" with no way forward: the chosen key stayed in the account's slot, so every retry and every launch re-sent the same rejected bind. For an unclaimed account, the picker now also offers **Create a new identity**: - Creation writes only this account's empty identity slot, so every saved and device key is kept. - Creation is offered only when every current device key was among the choices shown, so a new identity never silently passes over a key the user didn't see. - Bound accounts, accounts with backups, pairing and pending import never offer it. When binding a chosen key is definitively rejected, the blocked screen offers **Choose a different identity**: - It appears only for a 400, 404, 409 or 422 from `/verify` in the current attempt, for the current account and pubkey, and never during pairing, whose transferred key is the only choice. Evidence from an earlier attempt is cleared before each bind. A challenge rejection, a 403, a 503 or any other ambiguous failure offers nothing. - Before releasing the slot, it rechecks the account: still unbound (`/current` and status), no backups, the same subject, and a slot that still holds that pubkey without a receipt. - It releases the slot only when another durable copy of the same key exists (the device inventory or another account slot), then verifies the slot is empty. No key is deleted: only the account's pointer to the rejected choice is cleared. A failed or refused release keeps the slot and the choice, so it can be retried in place or after a restart. - After release, the picker runs again and offers the saved keys plus creation. The recovery code lives in `hosted_flow_identity_recovery.dart`, a part of `hosted_flow.dart`, to stay within the mobile file-size limit. ### Related issue None found. ### Testing **Physical iPhone, a signed release build of `1fb633d55` installed over the existing app (keychain and saved identities kept):** a saved identity was rejected, then Choose a different identity, the picker, Create a new identity and Join your community. Joining then completed. This head differs from `1fb633d55` only in the guards for leaving, pairing and a failed or refused release listed below, which this journey does not reach, and in no UI code. The status of that phone's original rejection was not captured, so it is not confirmed to be one of the rejections above. The 409 case is covered by tests. **Tests (red on `main`, green here):** - Identity service and store: creation beside offered keys; refusal for unseen or partly offered device keys; release when another copy exists; refusal for a sole copy, a binding, a backup, a receipt, another account or an unusable recheck; failed delete and retry; a cancelled attempt. - Onboarding journeys: create beside saved keys; select, rejected bind, restart, choose a different identity, create and bind; ambiguous 503 and 403 failures; challenge rejection and stale evidence. - Release boundaries: an account switch at `/current`, at status, or between the recheck and the delete; cancelling between the recheck and the delete; leaving the picker before a late creation; an unreadable device inventory; leaving while a release is in flight; a failed delete retried in place and after a restart; a release refused because the inventory is unreadable, then retried in place; a rejected paired key. Each keeps every key, leaves the new account's slot untouched and leaves a cancelled flow idle, and a retry converges. - Mutating the creation guard, the generation check, the binding recheck, the store's receipt check, the account and cancellation checks before the delete, or the device-inventory error handling fails a test. #### Screenshots Physical iPhone at `1fb633d55` (frames from a screen recording; saved public keys redacted): | Rejected bind | After Choose a different identity | After Create a new identity | | --- | --- | --- | |  |  |  | Widget-test renders of the same screens (the real `HostedFlow` against a mocked account service, with a fixture key; the square at the top left is the test renderer's placeholder for an asset): | Picker on an unclaimed account | Rejected bind | | --- | --- | |  |  | 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: John Tennant <jtennant@squareup.com> Co-authored-by: Xander <ff30c859b96bd5233ffaf5d071200458f1274bd0dab03589214cf1055198491d@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-05 14:23:59 -05:00
Tom Brow	244038b495	mobile: reuse channel message rows that did not change (#9115) ... Opening the keyboard in a busy channel janked: the composer's bottom inset changes on every keyboard animation frame, and each change rebuilt the message list, which rebuilt every visible message row. On an iPhone 12 mini that came to 8 frames over 16 ms per keyboard open, with 290 to 360 ms spent in build. The same cascade runs on every page rebuild, such as the dozen or so while a large channel settles after returning to the app. Flutter skips a rebuild only when it gets the identical widget object back, so the message list now keeps each row it built and returns it while nothing the row is built from has changed. Shared inputs (the message list, membership, channel names, send animations, the focus callback, today's date and so on) clear the cache when they change. Each row also compares its neighbors, thread summary, typing and working state, and send-animation and handoff flags. Rows still rebuild through their own provider watches. The composer's focus callback is now stable so the page's rebuilds don't clear the cache. ### Validation - Added `a growing composer reuses the message rows on screen`: it types a four-line message and checks that the visible rows are the same widget objects. It fails without the cache. - `flutter analyze` is clean. The full mobile suite passes except the 10 push and notification-toggle tests that fail identically on unchanged main on this machine. - iPhone 12 mini, Profile build, a 2,000-member channel, one matched run each before and after (the after column is an earlier revision of this change with the same mechanism): | | Before | After | | --- | --- | --- | | Keyboard open, build time | 359 ms, 290 ms | 64 ms, 43 ms | | Keyboard open, frames over 16 ms | 8, 4 | 1, 0 | | Return to the app, build time | 953 ms | 881 ms | | Return to the app, frames over 16 ms | 21 | 18 | Most of what remains on return comes from rows' own watches (for example the agent display-name map is a new object on every agent directory reload), which this change doesn't address. - Automated app run on the same phone with this exact branch: Home, opening the large channel, opening the keyboard twice (58 and 69 ms of build, one frame over 16 ms each), scrolling back through several days of history, and returning to the app after 12 s in the background. Day dividers, reply counts, reactions and system rows rendered correctly throughout. Typing is covered by the widget test rather than the device run, to avoid drafting in a real channel. - Simulator QA of this branch (Debug build, a private test channel): typing a four-line message, sending, scrolling to the top and back, a reaction, an edit, a thread reply, a delete, sending again, and backgrounding and returning. Every row rendered and updated correctly, with no replayed send animations. The jump-to-latest button didn't respond to synthetic simulator taps before or after resume; it's a native iOS view this change doesn't touch. https://github.com/user-attachments/assets/04909261-81fe-4514-98aa-8d7fdfdcace5 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-05 11:15:32 -08:00
Tom Brow	e34acb0ac5	fix(mobile): keep reply counts on screen while a reconnect catches up (#9100) ... Every time the app comes back from the background, the "N replies" links under messages in an open channel vanish and reappear a moment later. On an iPhone 12 mini in a busy channel this happened on nearly every resume, since the session drops its socket five seconds into the background and the channel reconnects. A reconnect discards the channel window and refetches its newest page. Until that page lands, thread summaries came only from replies already loaded, which in a windowed channel is usually none. The discarded window's summaries now stand, below every fresher source (live summaries, thread queries, overflow floors), until the replacement history lands, which then decides, including dropping a summary the relay no longer reports. ### Validation - Added `reply counts stay on screen while a reconnect catches up`, which fails when the retained summaries are left out. - `flutter analyze` is clean and the full mobile suite passes. - iPhone 12 mini, Profile build, a 2,000-member channel backgrounded 12 s and resumed (same scenario, one run each). Before: the "6 replies" link vanished for about a second and the timeline shifted up, then back. After: the link and the scroll position stay put through the catch-up. - Automated app run on the same phone with this change: Home, search, the large channel and its resume after the reconnect grace period. ### Accepted gap If you had scrolled back past the first page, those older rows still lose their reply counts once the reconnect catch-up finishes, as they do on main today. Their counts return when pagination refetches their page or the channel is reopened. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-05 11:14:52 -08:00
Tom Brow	6b8a72e835	fix(mobile): send hosted relay auth with iOS custom emoji downloads (#9056) ... On iOS, custom emoji in the native emoji picker often render as the sparkle fallback icon instead of the image. The native picker downloads custom emoji with `URLSession` and asks Flutter for request headers over the `mediaHeaders` channel call. That call returned only the media read `Authorization` header. Hosted relays also require the `Nostr-Federated-Identity` assertion, which the Flutter image path gets from `HostedRelayHttpClient`, so relay-hosted emoji get a 401 and the picker falls back to sparkles. Emoji hosted elsewhere still load, which is why only some are missing. The `mediaHeaders` bridge now also includes the hosted relay assertion via a new `HostedRelayAuth.headersForUrl`, scoped to the relay's own origin like `HostedRelayHttpClient`. The native loader refuses redirects for requests that carry the assertion, matching the Dart client, so the token can't be forwarded to another host. The iOS reactions sheet had the same gap: it passes avatar and custom emoji URLs to native views with only the `Authorization` header. A new `nativeMediaHeadersProvider` combines both headers for any native media consumer, and the reactions sheet uses it. ### Validation - Added tests: the native picker's `mediaHeaders` call returns the relay assertion for relay media and no headers for an external emoji URL; `headersForUrl` returns the assertion only for the relay origin (not another host, subdomain or port). The reactions sheet passes the combined headers for avatars and custom emoji, and `nativeMediaHeadersProvider` merges both headers only for relay URLs. - Focused existing validation: the emoji picker and organization relay auth suites pass, and `flutter analyze` is clean. In the full mobile suite, the only failures are 10 in `notification_toggle_test`, `push_bootstrap_test` and `push_bridge_test`, and they fail the same way on `main`. - Automated full-app simulator run (iPhone 17 Pro, iOS 27, debug build of this branch with hosted auth enabled, signed in to two hosted communities through a cloned simulator keychain, driven with AXe). Covered: launch signed in, channel and DM lists, opening a channel and a DM, the native emoji picker (its Custom section shows the emoji as an image, not the sparkle fallback), sending a custom emoji message and seeing it render, reacting with the custom emoji (shown in the quick-reaction row and as a reaction pill), opening a thread, switching communities, avatars and community icons, background and resume, and a cold relaunch. Result: no crashes or regressions seen. Screenshots are omitted because they show real account and community names. - Limitations: this run does not reproduce the original bug. The hosted community's custom emoji also loaded in a temporary build with the relay assertion removed from the `mediaHeaders` bridge, so its emoji URL evidently doesn't need the assertion, and the run doesn't prove the fix. The reactions detail sheet could not be reached because simulated long presses on the pill opened the message menu, and inline image attachments were not exercised. A device build against a community whose emoji are relay-hosted is still needed to confirm the fix. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-05 04:27:16 -08:00
Tom Brow	920b1e64bd	perf(mobile): keep covered pages still while the keyboard moves (#8941) ... ## Summary A keyboard raised by a route above (the Add members sheet, search, a native picker) changes the app's `MediaQuery` on every animation frame. Covered pages that read `MediaQuery` directly or through a `Scaffold` rebuilt and relaid out all their content for keyboard motion they cannot show. On #4things, typing in Add members rebuilt every visible message of the channel page underneath for each keyboard frame. `CoveredRouteKeyboardInsets` holds a page's `viewInsets` and `padding` at their last values from when its route was current, while the route is covered. Every other `MediaQueryData` field passes through. A covered page still follows the keyboard down, so when a covering route takes focus and the page's own keyboard closes, the page lowers behind the scrim. A size change (rotation) drops the held values so safe-area padding stays right. When the route becomes current again with the keyboard still above the held value, the page keeps the held values rather than jumping up and riding the keyboard back down. It switches to live values once the keyboard reaches the held value, or as soon as focus is inside the route (the page raised its own keyboard). Otherwise the live values return. It always returns the same widget shape, so covering a page never remounts it. Home, search, the channel page and channel details use it. ## Measurements iPhone 12 mini, Profile build, Builderlab #4things (1,361 members). Flow: open the channel, open its details, tap Add members, tap the search field, then type "chris" one character per second. The window is the 10 s of typing, keyboard included. Both builds also contain the fixes from [#8928](https://github.com/block/buzz/pull/8928), [#8929](https://github.com/block/buzz/pull/8929) and [#8931](https://github.com/block/buzz/pull/8931). | | Before | After | | --- | --- | --- | | UI frame time, total | 3,344 ms | 383 ms | | Frames over 16.7 ms | 101 of 232 | 2 of 297 | | Median / p90 frame | 14.1 / 26.1 ms | 0.6 / 2.0 ms | | UI isolate CPU samples (1 ms) | 2,793 | 868 | | Samples in `MessageContent.build` | 621 | 0 | Single runs per side, not repeated. ## Testing - New widget tests: a covered page doesn't rebuild for keyboard frames and gets the live insets back when it's current again. A current page follows the keyboard. Covering a page keeps its state. A page uncovered with the keyboard still up does not jump, and follows the keyboard once it reaches the held value. A page whose own field takes focus after being uncovered follows the keyboard immediately. A covered page follows its own keyboard closing and takes new padding when rotated. The last test fails (3 mounts instead of 1) against a version that returned a different widget tree when covered. - `just mobile-check mobile-test` passes. - On the phone: Add members search, typing and results behave as before. The channel page and search still move above the keyboard when they're current. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@localhost>	2026-11-04 20:27:59 -08:00
Tom Brow	e558f15faa	Mobile: one New chat screen (#9079) ... Mobile had two New chat screens. [#8884](https://github.com/block/buzz/pull/8884) made the Flutter draft page (first send creates and names the chat) the New chat screen, but kept the older create form (a native iOS sheet, with a Flutter bottom sheet on Android) for one case: resuming a creation that an older build had saved with a chat name and no first message. Nothing creates that state anymore, so the old form only appeared for users with an interrupted creation from before that change. This removes the old form. Every New chat, including that resume case, now opens the draft page: - **New chat**: unchanged. - **Resuming an interrupted creation**: after the existing Resume / Discard setup / Later prompt, the draft page shows the saved chat with its agent and workspace locked and a Retry button, the same choices the old sheet offered when it locked its fields. A creation saved with a first message resumes exactly as before. One saved without a message finishes without one, because a saved creation can't change after its first relay write. The iOS editor's chat-only code (`presentChat`, `updateChatAssistants`, the agent list, and its avatar loader) goes too. The same editor still handles profile fields, channel details and workspace names.

New workspace still opened the native editor, enabled Create once named, and showed the Discard changes prompt on cancel.

The widget tests cover finishing it. - `solo_creation_tags_test` also covers a conflicting pending Solo organization edit during that Retry: the draft offers the Conflicting Solo changes dialog, keeps the saved creation, and the next Retry finishes it. 🤖 Generated with [Claude Code](https://claude.com/claude-code) buzz-review-completed --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 16:34:05 -08:00
morgmart	5d44038ea5	mobile: invite new users to create their first agent with a bold card (#9036) ... ## Summary New users had no cue that the slot at the bottom of Home is where they make an agent. A one-time, deliberately loud "Create your first agent" card now sits above the empty Bestie slot and points at it. - The card spans the screen above the bottom bar, with agent pictures (the same ones the empty slot cycles through) scattered around its edges and the message centered as plain text. It's allowed to cover part of the chat list. - It waits three seconds on Home, then pops up from the agent slot with the popover entrance (a quick fade, rise and scale). Leaving Home restarts the wait, so it never pops over another screen. With reduced motion it appears without animation after the same wait. - Tapping the card starts agent creation. The close button dismisses it for good, as does a screen reader's dismiss action, activating the slot, or ending up with a Bestie. Dismissal is remembered per account and community. Other taps on Home go through to the page and leave the card up. - It shows when remote agents are on, the Bestie preference has loaded with none set, and the account owns no agents yet. The last check keeps existing users who never picked a Bestie from being told to create their "first" agent. - It only shows while Home is the current route, so sheets and pushed screens hide it and it comes back afterwards if it was never dismissed. The card is a new `BuzzCallout.card` variant of the reusable `BuzzCallout` in the mobile design system (the plain tip variant stays available). It uses the inverse surface in light mode and the raised dark surface in dark mode (matching toasts), with an arrow, existing radius, spacing and popover elevation tokens, and stays phone-sized on wider screens. It grows to fit large text below its close button, and it has live-region semantics, so screen readers announce it. ## Screenshots These come from the widget test harness with the real agent pictures, at small (320), standard (393) and landscape phone sizes, plus a tablet. The harness can't render the native iOS glass bar, so these use the Flutter bar; the card is the same on both platforms. Pictures look a little soft because the harness renders at 1x and scales up. In landscape and on tablets the card stops at large-phone width so the pictures don't spread too thin. | Standard, light | Standard, dark | Small, light | | --- | --- | --- | |  |  |  | | Landscape, light | Landscape, dark | | --- | --- | |  |  | | Tablet, dark | | --- | |  | ## Testing - Launcher tests cover first show and placement, Home staying tappable underneath without dismissing, the card tap starting creation, the close button, slot activation without a touch, screen reader dismiss, a Bestie appearing, no reshow after dismissal, a separate community getting its own first run, staying hidden for people with agents or without remote agents, hiding under a sheet, the three-second wait and entrance, reduced motion, and leaving Home during the wait (each mutation-checked). - Component tests cover the tip beside an edge target (320 and 1024 wide, 3x text) and the card: full width at 320, capped on wide screens, growing at 3x text so the message stays clear of the close button (mutation-checked), and the close button staying its own screen reader control. - The full mobile suite passes locally with CI's dart-defines, and pre-push mobile checks passed at e2fdb791c. - Still needs a device check on a real iPhone with a fresh account. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: morgmart <98432065+morgmart@users.noreply.github.com> Co-authored-by: Carl <c217fe6b9d958f41c3a5e030dccc7f626775a923089cb6491305eade75ea1f1b@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Morgarita <6e967af659416160ab4f2fd56d74c8c6f273791ee7bfc9468a1be37c387947be@buzz.block.builderlab.xyz>	2026-11-04 15:40:10 -08:00
Wes	af54258f19	fix(mobile): streamline identity setup and community selection (#9070) ... Selecting a saved community now connects only that destination, and **Find my communities** remains available through **Switcher → Add Community**. Failed destinations are named; completing nested Add/Find opens the selected destination without resuming the outer batch. Fresh hosted account setup now creates and backs up an identity automatically through email sign-in, invites, community links and community creation when the resolver confirms there are no account-bound, backed-up, saved or device identities. Welcome has one email sign-in entry. Authenticated import, existing-key recovery and selection retain their explicit paths; pending import survives restart and attaching a destination. Backup retry retains the same identity. Web binding retains explicit identity creation and its browser-return behavior. Self-hosted setup is separate and explicit. New-key creation still requires platform sealing support; passive account restoration never creates, binds or backs up an identity. **Account tradeoff:** setup cannot discover a key stored only elsewhere and never associated with this account. Such an account receives a new backed-up, bound identity automatically. Importing a different old key afterward fails with a binding mismatch; this flow does not undo that account binding. There is no separate pre-authentication import button. Pending import now survives retained community/web-bind link decoding: internal import metadata is stripped before strict public-link parsing. Once an identity is saved and resolved, the import request is retired before binding or backup, so restart resumes the existing key. Passive restoration also repairs stale import intents written by earlier builds without creating, binding or backing up a key. Validation (`f114c0e228`): - All 30 hosted onboarding journeys pass. Import coverage includes invite-to-community-link retention, restart before import, failed-backup restart, successful-backup restart, and an older stale import intent. - Three isolated production mutations (decode filtering, import completion persistence, passive stale-intent handling) each fail the relevant journey; restored control passes. Earlier auto-creation and nested-selection mutations also failed their relevant journeys. - Carl reviewed both P2 fixes and the final commit with no blockers. Carl and Pinky previously cleared the shared setup behavior and Android parity. - Wes confirmed Android sign-in and fresh account creation on the preceding build `be5690c684`. Android/iOS builds and earlier manual acceptance do not establish native acceptance of the new import/restart fixes. Installed devices remain on that preceding build. **Remaining acceptance:** current-head CI and native validation of the import/restart edge cases. Required publication hooks passed, including mobile analysis/tests, branch-skew and file-size checks. The existing iOS 16 sealing limitation remains: it cannot create a fresh hosted identity. No membership/ownership repair, denial-classification change or floating sign-in-control fix is included. --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz>	2026-11-04 14:42:24 -08:00
Tom Brow	ec21753e1b	Make mobile New DM and Add members pick recipients like mention autocomplete (#9065) ... The mobile New DM picker listed the first 50 relay profiles alphabetically, mostly identities the viewer doesn't know. It ran its own debounced directory search with no cache, and its rows disappeared on every keystroke until the search returned. Mention autocomplete in the composer already solves the same problem well, so New DM and Add members now use its implementation. Add members was reusing the same New DM directory search. ### What changes - **Same candidates and order as mention autocomplete.** The chooser's candidate building, ranking, row stability, 200 ms debounced search and search cache now back both surfaces. New DM is treated like a stream with no members yet: the viewer's own agents and agents shared with them appear up front, people are found by name, and agents that couldn't answer the viewer are left out. Typing a name shows the same people in the same order as `@name` in a stream. - **Results stay on screen while a search runs.** A query searched before shows its people immediately, and a longer query starts from the shorter query's results. A failed search keeps its rows and adds a retry row below them. - **Presentation matches the mention rows.** Rows show the name, and agents show "agent · managed by …". Npub lines are gone. - **Sheet chrome.** The title is "New DM", like the menu item that opens it. Both pickers keep their grouped cards but drop the "People and agents" and "Selected" section titles and the empty header bands above them (selected recipients stay in their own card at the top with checkmarks on iOS, as chips on Android). The native iOS picker now focuses search once it appears, which iOS used to ignore. In New DM a pick clears the query, as an inserted mention ends its query. - **Add members keeps what is specific to it.** Existing members and members just added are never offered, names are still compared with the channel roster so a same-name candidate is told apart, the query stays after a pick so several matches can be added in a row, and agents that don't answer the viewer can still be added, since a channel can hold them. While the WebSocket reconnects, the relay agent directory and its owners keep their last read in the community instead of going empty, so shared agents already found stay eligible in both New DM and the composer chooser. The debug-only offline preview directory and the old directory listing and search providers are removed, since no picker reads them any more. ### Validation Added tests: the New DM widget journey now drives the real mention search through a fake relay session. It covers the empty-query state, the debounce, rows kept while a longer query searches, cached results shown again at once, selection, chips and submit. The layout journey covers the 50-row cap, and the native-bridge journey covers title, rows without key detail lines, the selection limit and failure handling. The full `mobile/test/features/channels` suite passes. Automated app run (iPhone 17 Pro simulator, iOS 27, debug build, Remote Agents Pilot community): opened New DM from the menu, confirmed the keyboard comes up with only the viewer's own agents listed, searched for people and an agent, selected both and confirmed the query cleared after each pick. Also exercised the composer mention chooser (same results and order for the same query) and the shared Add members sheet (plain style, autofocus, search, query kept after a pick). Captures show real community members, so they're shared internally rather than here. The DM was not actually created, to avoid a stray conversation; submit is covered by the widget tests. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 13:55:26 -08:00
Tom Brow	f09956179d	fix(mobile): keep the composer focused through iOS inactive spells (#9055) ... On iPhone, opening Control Center or the app switcher while the composer is focused can leave the keyboard up over a collapsed composer. The orphaned keyboard then stays put while you navigate, for example back from a thread to its channel, and it clips the composer pill. ### Cause iOS reports a zero keyboard inset while the app is inactive and restores the keyboard natively when the app returns. The composer treated any inset drop as a user dismissal: it collapsed, unfocused and removed its text field. When the keyboard came back, it was attached to no Flutter field, so nothing could dismiss it. Flutter's own report of the native side is [flutter/flutter#189051](https://github.com/flutter/flutter/issues/189051). ### Change The composer's keyboard observer ignores metrics while the app is not resumed. iOS reports `resumed` with the inset still at zero and brings the keyboard back a few hundred milliseconds later, so when a keyboard that was up hasn't returned at resume, the composer waits a one-second grace before treating it as dismissed. Any nonzero inset in that window cancels the wait. A restored keyboard leaves the composer expanded and focused; a keyboard that really stayed down still collapses the composer once the grace passes. ### Validation - Extended the existing "returns to the compact capsule when the keyboard drops" widget journey with both inactive cases in the order iOS reports them: resumed at zero with the keyboard returning about 400 ms later (composer stays focused), and resumed with the keyboard staying down (composer collapses after the grace). It fails without the fix and against the first revision of this PR. - Full mobile check and test suite pass. - iOS 27 simulator (iPhone 17 Pro, debug build of the first revision): focused the composer, typed, switched to Settings and back, opened and closed Control Center, sent a message, and left the channel. The composer stayed focused through each interruption, sending kept focus, and leaving dismissed the keyboard. Limitation: the simulator keeps the keyboard inset through these interruptions, so it reproduces neither the original bug nor the resume grace; the on-device inset drop is from the reporter's screen recording and the Flutter issue. Human app testing is waived under the mobile testing exception; the simulator pass above is the automated full-app run. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-04 13:54:12 -08:00
ravarora2	7b3c2f95f2	fix(mobile): bound notices to loaded message history (#9062) ... ## Summary Mobile reads system notices older than its loaded message window, even though those notices cannot yet appear. Bound notice reads by the oldest loaded message's timestamp to avoid fetching history outside the loaded time range. A short or empty bounded response finishes that time range, rather than all notice history. Preserve the full boundary second, resume when older message pages load, and keep notices before the first message available at the start of history. Enforce the 2,000-notice cap before fetching reactions. Reuse cached reactions and deletions when older pages reveal their notices. For channels with fewer than 500 notices, scrolling back can now require one bounded notice read per older message page. Previously, one unbounded read covered the channel. ### Related issue Related: #8962, which changed how mobile loads and displays membership notices. No duplicate notice-bound PR found in the open mobile-notice title search. ### Testing Mutation checks: removing the production `since` argument or restoring the old unconditional history-end flag each made all four notice-range cases fail. Command: `cd mobile && flutter test --no-pub --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example test/features/channels/channel_notices_journey_test.dart --name 'notice ranges'`. Replacing the captured message cursor with a fabricated maximum ID also fails the empty-range progress regression. Command: `cd mobile && flutter test --no-pub --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example test/features/channels/channel_messages_provider_test.dart --name 'an empty notice range'`. A read-only prepared-query check on local Postgres 17.10 used a representative kind-40099 query. It held 22 event-related relation locks with `force_custom_plan` and 99 with `force_generic_plan`. The generic plan pruned seven of eight partitions during execution but retained the broader locks. These results do not establish lock reduction or throughput improvement under the relay's actual cached-plan workload; a relay load test remains pending. Native app scrolling against a live relay and human confirmation remain pending. For the device check, run `just mobile-dev` on a host with an iOS Simulator runtime. Connect to a local test relay and open a channel with more than 150 messages and interleaved topic notices. Scroll back through at least three message pages, then to the start. Check that visible notices remain in order and appear once. Disconnect during a page read, reconnect, and continue scrolling to check recovery.

morgmart	0dd778f800	mobile: start new agents on Sonnet at medium effort (#9034) ... ## Summary The mobile create-agent screen opened with model and thinking effort blank, so the easiest path was picking from the full catalog, expensive models included. A new agent now starts on the first Sonnet model the catalog offers, at medium effort when that model supports it. People can still change either one. - An agent link that suggests a model still wins when Builderlab offers that model. - A setup resumed after a failure keeps the choice it saved. - If the catalog has no Sonnet model, both start blank like today. If the Sonnet model has no medium effort, only effort is left blank. Builderlab doesn't send a default or pricing, so the app matches on "sonnet" in the model id rather than pinning a version. That keeps working when the catalog moves to a newer Sonnet. ## Screenshots Captured from the widget test harness with a catalog listing Opus first, then Sonnet.

Tom Brow	f04fa0904c	fix(mobile): close the community switcher when the org relay refuses the key (#9042) ... ## Summary Follow-up to #9028 (merged). #9028 closes the community switcher before content loads when organization sign-in is needed, but it checks the session status once. When the session is signed in and the relay then refuses the paired key (`AccountFailure.denied`, which #9001 now saves on purpose), the Home banner offers **Retry** and **Use a different account**, yet the switcher keeps covering it until the 20s "taking longer" timeout. - `organizationSignInPromptVisible()` in `shared/hosted/organization_sign_in.dart` is now the single rule for when the banner has an action. The banner uses it, and so does the switcher. - The switcher listens to the sign-in session and relay auth while it waits for content, and closes as soon as the rule turns true. Listeners are removed on every exit, including the timeout, and the content wait stops listening once the prompt wins. - Relay failures stay scoped to the new community's relay and pubkey, so a stale failure from the previous community can't close the switcher. - `checking` no longer closes the switcher early (the banner is hidden then); a later transition to signed out still does. ### Related issue Related to #9001, #9009 and #9028. No duplicate PR found. ### Testing - New widget test: signed in, switch to an organization relay with content pending, then the relay refuses the key, and the switcher closes. It fails with #9028's one-shot check. - `flutter analyze` is clean.

Physical iPhone testing and successful real-relay checks in light and dark mode remain pending. On a build with this change, scan a desktop pairing QR code. Check that progress appears, Cancel returns to the entry form, and a fresh attempt reaches code entry. Paste a pairing code, cancel during connection, and check that the form keeps the code.

Logan Johnson	1055f79d04	fix(mobile): show a taken channel name plainly and keep invites working (#8807) ... ## Summary The relay is starting to refuse a new open channel when another channel in the community already has that name (https://github.com/block/buzz/pull/8782). Mobile handled that refusal badly in two places: - **Creating a channel with a taken name** showed raw error text: `Exception: invalid: an open channel named "Launch" already exists`. The create sheet now shows `An open channel named "Launch" already exists` and stays open, so the user can pick another name. - **Joining a community by invite could fail.** After an invite join, the app joins two starter channels, `#general` and `#welcome-everyone`, and creates either one if it can't find it. If an archived channel or a forum already holds one of those names, the relay now refuses the create, and the whole join failed. Now the app skips a starter whose name is held by a channel it can't use, and the join succeeds. If the holder is a live channel the app didn't see at first, the app joins that channel. Screenshots from an Android emulator against a local relay built from https://github.com/block/buzz/pull/8782 are in the Testing section. ## Details - **Error text.** A new `relayErrorMessage` helper (`lib/shared/relay/relay_closed_policy.dart`) removes the `Exception: ` wrapper and the relay's machine prefix (`invalid:`, `blocked:`, `duplicate:` and the other standard prefixes), then capitalizes the first letter. Only the create sheet uses it. The other error paths are unchanged. - **Starter channels** (`ensureStarterChannels` in `lib/app.dart`). After a taken-name refusal, the app reloads the channel list and looks for the channel that holds the name: - A live open stream with that name: join it. - An archived channel or a forum: skip that starter. An archived channel can't be joined, and a forum is the wrong type for a starter. - No visible holder: fail as before. The setup stays retryable, because the holder may not be visible yet. - **Which channel counts as the holder.** Only a channel that can hold the name under the relay's rule counts: open, not unlisted, a stream or forum. Channels now carry the relay's "unlisted" flag for this. An unlisted channel with the same name (for example, an unlisted forum the user is in) doesn't hold the name, so the app doesn't skip the starter because of it. - **A starter that was archived.** Desktop and mobile create each starter at the same fixed id. When the starter at that id is archived, the relay refuses a new create there with `invalid: channel is archived`. The app treats that as an archived starter and skips it, unless a live channel with the name exists. When the relay answers `duplicate` and the reload doesn't show the channel, the app reads the channel at the fixed id and skips the starter only if that channel is archived. - If `#welcome-everyone` is skipped, the join opens no particular channel. Both callers already handle that. ### Related issue None found. Client side of https://github.com/block/buzz/pull/8782. ### Testing Android emulator, debug build of 778a4cada, local relay built from https://github.com/block/buzz/pull/8782 at 0df245e3c, fresh database: **Invite join while an archived `general` holds the name.** The app skipped `general`, created `#welcome-everyone` at its starter id and joined it. The archived `general` did not change, and no new `general` was created.  **Create a channel with a taken name.** `ops` is live. Creating `OPS` shows the relay's refusal as plain text, and the sheet stays open.  Automated tests: `invite_join_provider_test.dart` has a table row for each holder case above (archived, forum, unlisted, appears late, archived at the fixed id for both relay answers), plus the scope fences. `channels_page_test.dart` covers the sheet text, and `relay_closed_policy_test.dart` covers the helper. Each new skip fails its row when it is removed. `just mobile-check` and `just mobile-test` pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 21:39:47 -05:00
Tom Brow	38a5d9a1ff	mobile: tap the settings version footer to copy it (#9021) ... ## Summary The version line at the bottom of mobile Settings (for example `v0.27.0 (36)`) couldn't be copied, which made it awkward to paste into bug reports. Tapping it now copies the whole string and shows a "Version copied" toast, matching the existing "Copy public key" row. It's keyboard-focusable and has a 48dp tap target. Partial selection isn't supported; it's whole-string only.  ### Related issue N/A ### Validation - Added test: tapping the footer, or reaching it with Tab and pressing Enter, puts `v0.16.0 (432)` on the clipboard and shows the toast. The test also checks that the tap target is at least 48dp tall. - `just mobile-check` and `just mobile-test` pass. - Automated simulator run (debug build, iOS 27): opened Settings, tapped the version, confirmed via `simctl pbpaste` that the clipboard held the exact footer text and the toast appeared; then confirmed the neighboring "Copy public key" row still copies the npub and Settings still closes. Human testing waived per the mobile testing exception.

Spencer Lewis	83d0bd3203	fix(mobile): stop QR pairing to organization relays from hanging (#9001) ... ## Problem Pairing a phone to an organization relay by QR (for example Block's `buzz.block.builderlab.xyz`) never finishes. After the codes match and the phone confirms, it sits on the loading surface. About 2 minutes later it returns to the welcome screen with "Lost connection to pairing relay." The desktop stays on "Finishing pairing on your phone…". This reproduces every time on Buzz 0.27.0, iOS 27.2, with desktop 0.7.7 (internal tracking: AIDA-2420). There are two causes: 1. **Validation can never pass for organization relays.** After the payload arrives, `_validateCredentials` opens a plain `RelaySocket` without a `Nostr-Federated-Identity` assertion. Organization relays refuse that upgrade with HTTP 401 until organization sign-in, which a freshly pairing phone hasn't done. 2. **The failure hangs instead of erroring.** `RelaySocket.connect()` catches the failed `ready` but keeps `_channel`. The validator's `finally` then awaits `disconnect()` → `sink.close()` on a channel that never opened, and that never completes. The phone waits until the pairing relay's 120 s connection cap closes the socket, and `_handleDisconnected` reports that as a lost connection. Standalone repro with `web_socket_channel` 3.0.3 against the real relay: ``` ready failed: ... was not upgraded to websocket, HTTP status code: 401 sink.close() DID NOT COMPLETE within 30s (hang) ``` ## Change - `RelaySocket.connect()` drops a channel whose upgrade failed. - `disconnect()` waits at most `RelaySocket.closeTimeout` (2 s). An upgrade that is still pending (connect timeout 10 s) can outlive pairing's 8 s validation deadline, and its close never completes either. - `PairingNotifier` skips the pre-sign-in check for `OrganizationEnvironment.protects` relays. Admission is left to the saved community's session and the existing organization sign-in banner, which matches how the hosted branch already defers admission. The predicate is injectable (`organizationRelay`) for tests. Other relays are still validated before saving. Trade-off: an identity that the organization relay would reject is now saved, and that rejection only surfaces after organization sign-in. The hosted path has the same property. ## Related issue No existing GitHub issue covers this failure; searched open issues and PRs for pairing relay, lost connection and `_validateCredentials`. Closest: - #8043 / #8060 cover the same `_validateCredentials` path from the other side: a failed connect currently returns normally. They're complementary. With #8060 merged, organization relays would fail pairing with an explicit 401 instead of hanging, and this PR keeps them out of that pre-check. Whichever merges second needs a small rebase in `_validateCredentials`. - #3181 is a different failure in the same flow. ## Testing - New `relay_socket_liveness_test` cases check that `disconnect()` completes in three situations: after a refused (401) upgrade, after a timed-out handshake, and while the upgrade is still pending. - New `pairing_provider_test` case: a malformed key is rejected locally before anything is saved, an organization relay is saved without the relay check, and a non-organization relay is still validated and rejected. - Each new test fails with its fix removed. The failures were "disconnect() hung on a channel that never opened", "disconnect() hung on a pending upgrade", and `validated` being true. - `just mobile-check` and `just mobile-test` pass: 4229 passed, 40 skipped. - **Simulator run (iOS 27.0 simulator, iPhone 18 Pro, Block organization dart-defines) against desktop 0.7.7 on `buzz.block.builderlab.xyz`:** pairing completed (desktop reported the phone paired; identity transferred; community saved) instead of hanging until the pairing relay closed. The app then showed the organization sign-in banner and opened browser sign-in for block.builderlab.xyz, as expected. Okta in the simulator requires FastPass, so the final relay connection after sign-in was not exercised there. - Human device testing is still pending. ## Follow-up - Test on a real phone with an organization build. The simulator couldn't complete Okta FastPass, so the relay connection after organization sign-in still needs checking. --------- Signed-off-by: Spencer Lewis <slewis@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 17:17:15 -08:00
Tom Brow	9f88eb9c45	mobile: hide self-joins and leaves, collapse membership runs like desktop (#8962) ... Busy channels fill the mobile timeline with page after page of small "X joined the channel along with Y and N others" and "X added Y to the channel" rows. Desktop now hides most of that ([buzz-app#2258](https://github.com/block/buzz-app/pull/2258)). This brings mobile's membership notices in line with desktop's current rules (`membershipRows` / `membershipDescription` in buzz-app `src/features/messages/membership-rows.ts`). ### Behavior - **Only explicit changes show.** Self-joins and voluntary leaves are hidden. That covers both relay leave shapes: a normal Leave (kind 9022, actor only) and removing yourself (kind 9001, with a target). Additions by someone else and removals still show. - **One row per run.** Each uninterrupted run of additions and removals becomes one row, whatever the elapsed time, local day or actor. Messages and other channel events (topic, archive, huddles) still split runs. - **Each person appears once**, under their latest change in the run. - **Wording:** - One adder: "Alice added Bob, Carol and N others to the channel. See all" (unchanged) - One remover: "Alice removed Bob ... from the channel" (unchanged) - Several adders: "Bob, Carol and N others were added to the channel". It no longer says they "joined". - Additions and removals together, or several removers: "Bob and 4 others were added · Dan was removed". Each "N others" opens that list. Mobile keeps its "See all" sheet in place of desktop's hover popover. ### Validation - Added tests: - unit tests for hiding self-joins and both leave shapes - grouping across hours, days and actors - runs split by messages and other channel events - a channel page journey with a self-join, a 9022 leave, a 9001 leave, additions by two people hours apart and a removal: it renders one mixed row, and the "1 other" sheet works - a several-adders wording test - Updated tests that previously relied on visible self-joins or leaves. - Full mobile suite (`just mobile-test`) and `flutter analyze` pass. - Automated full-app run on an iPhone 17 Pro simulator, signed in to a hosted community: - The home list and a 33-member channel with membership history load. Self-joins are gone, messages flow without them, and a two-adder run reads "X and Y were added to the channel". - Scrolling back through history and opening and closing a thread work. - Captures are not attached because they show internal names. - Limitation: the internal community now rejects the simulator's websocket without hosted sign-in, so the 1,500-member channel wasn't re-checked on this head. - Human testing is waived per the owner's standing policy. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-03 15:50:33 -08:00

klopez4212	8312419652	fix(mobile): size reply labels correctly with Bold Text (#9013) ... System Bold Text made single-participant reply labels such as “12 replies” wrap or truncate: the handoff measured normal-weight glyphs, then rendered bold glyphs inside that narrower box.

Addresses the fix-before-merge blocker identified by [Tom's agent on #8987](https://github.com/block/buzz/pull/8987#issuecomment-6611883349), specifically [the Bold Text finding](https://github.com/block/buzz/pull/8987#discussion_r4458491084). Tom classified unloaded-root typing, legacy reply-only paging, and working-state label clipping as acceptable later follow-ups; those remain outside this patch. Validation: - Regression loads the bundled Inter font (the default test font masks weight differences), toggles Bold Text off/on/off, and covers idle/working footers at 1x/2x scale. All four cases failed before the production fix. - Formatting and full analysis passed; 4,252 Flutter tests passed (44 skipped), plus 4 unconfigured-push tests. All 27 crypto tests passed. Mandatory push hooks passed. - Self-review found no blockers in this narrow change. Draft pending app/human verification required by AGENTS.md.

morgmart	c24b0f472e	Open the new Bestie's chat after creating it (#8972) ... Stacked on #8957 (Kenny's Bestie onboarding). In #8957, tapping the empty Bestie slot opens Create agent, and saving a first agent makes it Bestie, but you land back on home and need a second tap to start talking. This takes you straight into the new Bestie's chat once creation finishes, which matches where the group DM landed: pick a name and avatar first, then you're chatting with it. - Creating a first agent from the empty slot opens its chat. - Cancelling, or creating an agent that doesn't become Bestie (you already own others), still returns home as before. - The slot stays disabled while the create flow is open, so a double tap during the account check can't open it twice. - Opening an existing Bestie is unchanged; that code just moved into a shared step. Validation: new widget test covers both the create and cancel paths, and it fails without the change. The mobile widget tests touched by the launcher pass (508), and `flutter analyze` is clean on the changed files. Not yet checked: creating an agent on a real device. #8957's recording also stops before submit, so the real create → chat handoff (including how long the new agent takes to appear) still needs a device run. --------- Signed-off-by: morgmart <98432065+morgmart@users.noreply.github.com> Signed-off-by: kenny lopez <klopez4212@gmail.com> Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Carl <carl@agents.local> Co-authored-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Morgarita <6e967af659416160ab4f2fd56d74c8c6f273791ee7bfc9468a1be37c387947be@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 12:59:20 -08:00
John Matthew Tennant	33eaa73c83	fix(mobile): let users sign out after leaving all communities (#8993) ... ## Summary Fixes a dead-end in signed-in mobile onboarding: after leaving every community, Back kept returning to the same Add a community screen without a way to end the account session. Show “Signed in as [email]” on that screen. Back asks “Sign out of BuilderLab?” with the email; Cancel keeps the session, and Sign out returns to the welcome screen while retaining saved Buzz identities. Nested Back and Add community from an existing session keep their navigation behavior. ### Related issue None found in the existing issue and PR search for onboarding sign-out. ### Testing The new widget journey failed before the change and passes through the real onboarding widgets, account client, storage and flow with external HTTP/browser boundaries mocked. It covers nested Back, Cancel, system Back, durable session removal, retained identity/backup, and starting email sign-in again. The existing hosted onboarding journey also covers accounts without an email. On iPhone 18 Pro simulator (iOS 27), rendered the production onboarding screen and native confirmation using a disposable account fixture. Live browser account selection has not been verified; this clears the app session, not website cookies. To reproduce on an auth-enabled mobile build: sign in, leave all communities, check the displayed email, tap Back, and choose Cancel. Tap Back again and choose Sign out. The yellow welcome screen should appear, with email sign-in available. ## Screenshots Before, from the original reported phone screen: <img src="https://raw.githubusercontent.com/block/buzz/07440b3b10c3f48a6fd19c923f2ee5ba66d574f0/pr-8993--before.png" alt="Before: account state not shown" width="300"> After: Signed-in landing and native sign-out confirmation, using a disposable account: <img src="https://raw.githubusercontent.com/block/buzz/a4e18c85bc3a19d971b08ff595ba6b081c67e20f/pr-8993--landing.png" alt="Signed-in landing" width="300"> <img src="https://raw.githubusercontent.com/block/buzz/a4e18c85bc3a19d971b08ff595ba6b081c67e20f/pr-8993--confirmation.png" alt="Sign-out confirmation" width="300"> --------- Signed-off-by: Aaron <f425b86c3b780d43f8d9cf1802429d04dd985bf92eac44fca9468b5ad3887c5e@buzz.block.builderlab.xyz> Signed-off-by: John Tennant <jtennant@squareup.com> Co-authored-by: Aaron <f425b86c3b780d43f8d9cf1802429d04dd985bf92eac44fca9468b5ad3887c5e@buzz.block.builderlab.xyz>	2026-11-03 18:25:54 +00:00
klopez4212	3f03aa0450	fix(mobile): restore ordinary DM behavior for Bestie (#8987) ... Mobile Bestie used a special flat timeline that hid reply threads. It now opens the normal DM screen, matching desktop’s pinned Bestie (block/buzz-app#1935), with existing threads, reply actions, and top-level sending in the same conversation. Thread-scoped agent typing in DMs stays beneath its originating message. Working avatars and mobile’s bouncing dots share a compact neutral container, matching desktop’s subtle activity control. The elbow is visible from the start, with the working container already at the final thread-footer position. For a single-agent reply, the same avatar stays mounted while the container and dots fade out over 200 ms, the avatar slides into its summary position, and the reply count fades/scales in from 95%. The elbow stays fixed. Reduced motion switches immediately. The avatar-to-dots gap is 4 points. Reply text uses its natural line height so its glyphs center on the avatar and elbow rather than drawing at the top of the footer. Multi-participant summaries retain their grouped layout. The accessible View thread action, reaction placement, and final reply-footer position are preserved. Validation: - The final commit (`c6fef5d80`) passed full analysis, 4,220 Flutter tests (40 skipped), 4 push-configuration tests, and 27 crypto tests. - Container alignment checks pass in both directions, including avatar continuity, intermediate fade and final geometry, reduced motion, and thread actions. Glyph-box alignment is checked against the avatar center. An additional regression covers a reply arriving before typing stops and work restarting mid-transition. - Updated DM journeys cover opening Bestie, existing threads, threaded and top-level sending, swipe-to-reply, and absence of duplicate main-row thread typing. - Installed the final product source (`c6fef5d80`) in place on Pixel 10 and iPhone Air previews. The iPhone uses a release-mode preview so it launches from the home screen; saved Kenny Lopez / Starry Night conversation verified after install. Pixel retains Testing Agent Sessions. The pending/midpoint/completed handoff was rendered in widget checks, and the corrected reply-label alignment was verified on the Pixel against the same messages before and after; human acceptance of this final animation remains pending. - Mandatory push hooks passed, including file-size and branch checks.

klopez4212	344f007f36	Add mobile Bestie onboarding and fix remote agent presence (#8957) ... An empty Bestie slot cycles still posters from Fuzzies, Gloopies and Figgies every five seconds, without creating video players. The next poster is precached; reduced motion and hidden-screen pauses are preserved. The launcher uses the neutral “Bestie” label until a selection is available, then “Chat with …”. For supported communities with no owned agents, tapping opens Create agent directly. A successful first-agent setup saves that agent as Bestie without replacing an existing preference; existing-agent and unsupported-community paths keep the Agents list. Verified Builderlab registrations can show sleeping remote agents as Online. Owner-scoped saved runtime availability now prevents a known absent or deleted runtime from returning Online after Builderlab sign-out or a fresh load, even when another community retains its registration. Validation: mobile static checks; 4,274 Flutter tests passed with hosted flows enabled; launcher → cancel → create → Home “Chat with Scout”, including encrypted persisted selection; sign-out, fresh-load, owner isolation and deletion regressions. Restoring the old carousel produced three video-player requests; removing the saved-availability guard reproduced incorrect Online after sign-out. The earlier iPhone recording below shows the original carousel and entry flow and stops before creation. The new poster-only behavior and completed creation are covered by widget tests, not a new device recording. https://github.com/user-attachments/assets/94fcff72-967a-44c2-99d5-27c715e196a2 --------- Signed-off-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz>	2026-11-03 18:10:28 +00:00
Tom Brow	369e1ef322	perf(mobile): stop re-parsing message markdown on every rebuild (#8928) ... ## Context Each message in a channel shows its text as Markdown. The `GptMarkdown` widget parses that text. Parsing is slow for long messages. `GptMarkdownTheme` gives Markdown colours and styles to the widgets below it. When it gets a new theme data object, it tells all `GptMarkdown` widgets below it to parse their text again. It compares the old and new objects by identity, because `GptMarkdownThemeData` has no value equality. Thus a new object with the same values also causes a parse. ## Problem Two widgets made a new theme data object on each build: - `MessageContent` made one for each message bubble. - `AppMarkdownTheme` made one for the full app. Thus each rebuild parsed all messages on the screen again. Many events cause a rebuild: a batch of profiles, a read marker, a keyboard frame. In a large channel such as #4things (1,235 members), these events occur almost all the time. ## Change - `MessageContent` keeps its bubble theme until one of its inputs changes. The inputs are: the app Markdown theme, the link colour, own or other message, the ink colour and `onSurface`. - `AppMarkdownTheme` makes new theme data only when `ThemeData` changes or when an outer Markdown theme changes. A change of colour, of brightness, or of own or other message still makes new theme data. Then the Markdown parses again with the new colours. This is correct. ### Related issue None found. ## Testing - New regression tests fail on main. They pass on this branch. - `message_content_stability_test.dart`: When a bubble rebuilds with the same inputs, it keeps the same theme object and the same parsed `TextSpan`. The test does this for own messages and for other messages. When own or other changes, the bubble gets a new theme. - `app_markdown_theme_test.dart`: The app keeps one theme object when it rebuilds. It makes a new one when light or dark mode changes. - `just mobile-install mobile-check mobile-test` passes. - Device test: iPhone 12 mini, Profile build, Tom's Block community, open #4things. The two runs had different live traffic and different cached content. Thus they show the cause and the fix. They do not give a controlled speed measurement. - Before: In the first 2.4 s, parses from rebuilds (`performRebuild`) used approximately 90 ms. One frame used 116 ms. Approximately 48 ms of that frame parsed visible messages again. - After: In 30 s, rebuilds caused no parses. Only the first build of each message (`_firstBuild`) parsed. - An independent agent review found no defects. It found one small item: `ChatColors` has no value equality.

Tom Brow	cad7f1d53d	perf(mobile): build composer channel names once per channel list (#8943) ... ## Summary `_useComposerChannelNames` ran on every `ComposeBar` build. Each time it built a lowercase-name to id map over every channel and joined every entry into a string key, only so a `useEffect` could skip calling `setChannelNames`. The composer rebuilds on every keystroke and keyboard animation frame. This memoizes the map and key on the channel list instance. The effect is still gated on the content key, so an equal new list still doesn't call `setChannelNames` again. ## Measurements iPhone 12 mini, Profile build, Builderlab, raising the composer keyboard in #4things: `_useComposerChannelNames` was 26 of 31 `ComposeBar.build` CPU samples (about 26 ms of UI work across the 600 ms raise). Limitation: I haven't re-measured on the device after the change. The removal is shown by the test below. ## Testing - New test: rebuilding the composer 5 times (keyboard insets and typing) with the same channel list doesn't iterate the list again. It fails with the change reverted (8 iterations instead of 3). - New test: changing the channel list still updates the composer's channel chips. - `just mobile-check mobile-test` passes (pre-push hook). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 08:00:19 -08:00
Tom Brow	fc9e652c0e	perf(mobile): format a channel timeline only when its events change (#8929) ... ## Summary The channel page ran `formatTimeline` on every build. The page also rebuilds for changes unrelated to messages: read state, presence, the roster, keyboard and layout. `formatTimeline` walks every loaded event and JSON-decodes each system row. In #4things (1,235 members, mostly join rows), on a 12 mini Profile build: - 58 ms of main thread over 21 idle seconds. - About 11 ms per frame while the keyboard animated. The messages notifiers publish a new list for every event change, so this memoizes the result on that list, the current pubkey, and the forum flag. `buildMainTimelineEntries` and the relay thread summaries it reads stay outside the memo. A summary-only update that republishes the same list still shows up. ### Related issue None found. ### Testing - Updated `loading_review_tests.dart`: unrelated page rebuilds now format the timeline 0 times, where main formats once per rebuild (the test fails on main). A new live event formats exactly once, and its message appears. - `just mobile-install mobile-check mobile-test` passes. - Device (12 mini, Profile build with this change, #4things idle). Runs are not matched, so this shows the mechanism, not a controlled speedup. - Before: 58 ms over 21 s. - After: 7 ms over 18 s, all from real event changes. - An independent agent review found no defects. It checked that `formatTimeline` reads only its arguments, that every publish path creates a new list or republishes unchanged events, and that nothing downstream mutates the shared result. Not covered: a human test (waived under the mobile testing exception; this was an agent-driven device run), and Android. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-03 08:00:11 -08:00
Tom Brow	76bc66acfc	mobile: hold a queued list read for the 10s gap (#8958) ... ## Summary Follow-up to [#8910](https://github.com/block/buzz/pull/8910) for the two optional notes from its review: - **A queued list read now waits out the 10s gap** ([note](https://github.com/block/buzz/pull/8910#discussion_r4447689472)). If a change comes due while a slow read is still running, the read is queued. When the slow read finished, the queued one used to start right away, even if the gap after the previous read hadn't passed. That broke the "reads start at least 10s apart" rule: a read could start 9s after the one before. The queue now drains through `_readListIfChanged`, which holds the read until the gap ends. If the finished read already covered the change, nothing is read. - **A test for a partly failed unread catch-up** ([note](https://github.com/block/buzz/pull/8910#discussion_r4447689485)). Previously, deleting the line that retries a catch-up when only some channels' fallback reads failed left the suite passing. ### Related issue N/A. Follow-up to [#8910](https://github.com/block/buzz/pull/8910). ### Testing - New step in the open-list journey: the relay answers each of a read's two queries in 7s. A change that comes due while that read runs is read once, after the gap, not as soon as the slow read ends. Restoring the old drain fails the step. - New step in the resume journey: after a reconnect, the batched catch-up fails over to per-channel reads, and one channel's read is refused. That channel turns unread on the retry, and nothing more is read over the next 10 minutes. Removing the partial-failure retry fails the step. - `FakeRelay.holdQuery()` holds HTTP queries, so a test can make a read slow. - The full mobile suite passes, and `dart format` and `flutter analyze` are clean. - This is a timing-only change to background list reads, with no UI change. The journeys above drive the real notifiers against a fake relay.

Tom Brow	009dc103f6	perf(mobile): read the channel list after live changes, not every minute (#8910) ... ## Summary While the app is open, a 60s timer reads the whole channel list again: every membership roster, the channel metadata, and the unread catch-up. On the test account that is **about 4MB of JSON every minute** on the 12 mini, about 240MB an hour, whether or not anything changed. The live subscriptions already deliver what the list is built from, so this PR removes the timer. The list is read again when a live event says it may have changed: - a relay notice that tags this reader: added to a channel or a new DM (kind 44100), removed from one (44101), or a DM hidden or shown on another device (30622) - a metadata edit on a listed channel (kind 9002, now part of the live filter) - a system notice on a listed channel that changes the channel itself: archived (including the relay auto-archiving an idle ephemeral channel), unarchived, deleted, visibility, topic, purpose, TTL and similar. Member joins and leaves don't count. The read starts 2s after the last such event, and no later than 10s after the first, so a burst costs one read. Reads start at least 10s apart however busy the relay is. A read that fails is retried with backoff (5s, doubling up to 5 minutes), including the read after a resume or reconnect. Nothing is read in the background: launch, resume, reconnect and pull to refresh read the list as before. Live subscriptions ask for no stored events (`limit: 0`), so nothing sent while one is down is replayed. So: - Each list read opens the notice subscription before it reads, and the read covers anything sent before. - If the relay closes the notice subscription or a channel chunk for a reason that may clear (busy, rate-limited, timed out), the relay session reopens it itself, as before. The channel list now hears about that through `subscribeWithStatus`. - If the relay refuses one as over its subscription limit, only that REQ is retried, after a jittered backoff (5s, doubling up to 5 minutes). The backoff starts over once a reopened subscription has stayed up for a minute. Any other refusal (`restricted:`, `invalid:` and so on) can't succeed unchanged, so it is left alone until the next connection, as on main. - A reopened subscription that is still up when its read comes due counts as a change, so the list is read once to catch up on what it missed. If the relay admits a REQ and then closes it again, it triggers no reads. Known gaps, accepted: deleting a channel or kicking a member sends this reader no notice, and archived channels have no live coverage, so an unarchive done on another device isn't seen. An edit to a newly added channel that lands in the round trip between reading its metadata and its live subscription starting is also missed. The list catches up on the next launch, resume, reconnect or pull to refresh. Archiving or unarchiving on this device re-reads the list at once, as before. ## Measurements iPhone 12 mini on Wi-Fi against the internal relay, app open and idle, instrumented profile build (HTTP response bodies after decompression, websocket text in). Measured on an earlier revision of this PR, which read on a 60s tick only after a change. Idle behavior is the same now (no change, no read). | 10 idle minutes | main | this PR | | --- | --- | --- | | Channel list reads | 10 | 1 | | HTTP queries | 40 | 5 | | HTTP response bytes | 39.9MB | 4.0MB | | Websocket bytes in | 4.4MB | 1.1MB | On main, every tick read memberships (348KB), another 310KB query and the unread catch-up (3.3MB). With this PR, the only read in the window came right after another device hid or showed a DM (kind 30622), which is exactly the kind of change it should pick up. Sizes are JSON after decompression; the relay gzips responses, so wire bytes are smaller (not measured). [#8901](https://github.com/block/buzz/pull/8901) separately shrinks each read's unread catch-up; the two are independent. ## Testing - New journey test: with the app open and nothing changing, nothing is read. Adding the reader to a channel, renaming a listed channel, archiving or auto-archiving one and removing the reader each cause one read about 2s later, and a member joining causes none. A change right after a read waits out the 10s gap. A steady stream of changes is read after 10s and then no more than every 10s. A burst costs one read. A failed read is retried with backoff and then stops. - New journey test, for the notice subscription and for a channel chunk: the relay refuses it twice as over its limit while the list changes. It is retried with backoff, and once it has stayed up the list is read once to catch up. Later the relay drops it, and having stayed up it is reopened within about 5s and catches up again. Then it delivers live. The relay then closes it as busy while the list changes, and the list catches up once it is back; closed again right after reopening, it triggers no read until it stays up. Refused as `restricted:`, it is not retried. - The resume journey: a reconnect read and a resume read each fail once while a channel is added, and each is retried and shows the channel. - Each guard was removed once to confirm a test fails: the debounce, the max wait, the minimum gap, the read retry (including after reconnect and resume), the catch-up reads after a retry or a relay-session reopen, the still-up checks, the backoff restart, the background check, retrying only capacity refusals, and clearing refusals on a new connection. - The terminal-rejection tests expect a chunk refused as `restricted:` never to be retried on that connection or to cause a list or history read, and a new connection to retry it at once. - `just mobile-check` and `just mobile-test` pass. - Device: on the 12 mini, 10 idle minutes with the app open, before and after (table above). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-02 13:13:16 -08:00
Tom Brow	fa395e9e80	feat(mobile): open a prefilled Create agent form from Builderlab agent cards (#8912) ... Builderlab agent cards (printed for the event, and generated at the kiosk) carry a QR to a share page, `app.builderlab.xyz/a/<id>`. Its **Add to Buzz** button opens `buzz://agent/new?card=<id>`, which no Buzz client handled until now. This PR makes mobile handle it. ### Behavior - Opening the link shows the Agents page, then a Create agent form prefilled from the card. Everything stays editable, and nothing is created until the user taps Create. - The app fetches the card's `agent.json` from the avatars CDN for this build's Builderlab environment (production or staging). The link carries only the card id, never a host, so the QR stays small no matter how long a card's instructions get. - `agent.json` is validated against the card schema. `id` (matching the link), `name` and `avatarUrl` (an https URL) are required. `instructions`, `model` and `reasoningEffort` are optional (published cards don't have them yet) and left for the user when absent. A missing required field or a wrongly typed known field rejects the card; any other key is ignored whatever its type, including `v` and `description` (Buzz agents have no description to prefill), so Builderlab can add fields without breaking released apps. The model and effort are preselected only if the live catalog offers them. The card id is opaque: any non-empty id is accepted and percent-encoded into the URL. - The fetch uses the same limits as image downloads, now shared in `bounded_fetch.dart`: aborted after 20 s without a byte or 5 min overall, and rejected over 2 MB. `MediaImageProvider` now calls the same helper, with no behavior change. - The link waits for sign-in, then reloads the registry for the signed-in account before anything else. It's dropped with a message if the card is unavailable (403/404), invalid, can't be loaded (any other response), or an agent setup is unfinished, including a setup saved before a sign-in the link triggered. - A link that arrives while Agents shows only its list replaces that page instead of stacking a second one. If a form or sheet is open there, the link is dropped with "Finish or close what’s open in Agents, then reopen the link." and the open work is kept. ### Demo Simulator (iPhone 17 Pro, debug build of this branch plus the sign-in fix from [#8914](https://github.com/block/buzz/pull/8914) and the hidden debug banner from [#8915](https://github.com/block/buzz/pull/8915), signed in to Builderlab, remote-agent-pilot), recorded in one take with idle time trimmed: the card's share page in Safari, Add to Buzz, the prefilled Create agent form, a model, thinking level and instructions, Create, then a message and the agent's reply. https://github.com/user-attachments/assets/e66aae17-884a-4e68-a1b8-ecb40562be1d ### Validation Added tests: - Table tests for the link shape (only `?card=<id>` with an opaque id; the inline `#` form, extra parameters and dot segments are rejected) and for reading `agent.json` (a published card, a card with instructions and model defaults, unknown keys of any type ignored, including `v`, `description`, arrays, objects and null, and invalid cards: missing or mismatched required fields, wrong types, and non-https or relative avatars). - Table tests for fetching: the request goes to this build's CDN without following redirects, with the id percent-encoded as one path segment; 403/404, a redirect, a 500, a network error, declared and streamed oversize bodies, non-JSON and a JSON array each give a specific message. The image loader's existing stall, deadline, cap and cancel tests now cover the shared helper. - A journey test from link to Create against a fake CDN: prefill and edit, then submit; an unavailable card; a failed model catalog whose Retry then preselects the card's model; a Builderlab account change while the card loads, which drops the draft; a v1 card with no instructions and an unknown model; an unfinished setup; a link arriving while a Create form with edits is open, which keeps the form and its edits; and a link arriving while Agents is open. Disabling the https or id check makes the table test fail, and removing either the account recheck or the loaded-catalog check fails the journey. The journey runs through the production root scope (removing its link handler fails it) and runs in CI's configured-authentication-domains step. Full mobile check and test suite pass locally. Live data: a real staging card's `agent.json` (`av_MioTAG6dm7q3Zcm0UV2j8A`) has the v1 shape the table test uses, and an unknown id returns 403 from the CDN. Live run on an iPhone SE (build of 63ed54c749, Builderlab sign-in enabled, remote-agent-pilot, signed in as builderlab@tombrow.com) with a real production card, [ToastyMacbeth](https://app.builderlab.xyz/a/av_lrmRlJR6ylrQKvJkoLWCOQ) (a v1 card with no instructions and an extra `description` key): - Opening `buzz://agent/new?card=av_lrmRlJR6ylrQKvJkoLWCOQ` from a cold start opens Create agent prefilled with the card's name and avatar. - After choosing a model and adding instructions, Create adds the agent with the card avatar, and it replies in a DM. - An unknown card id shows "This agent card isn’t available." | Prefilled | Created | Reply | Unknown card | | --- | --- | --- | --- | | <img src="https://raw.githubusercontent.com/block/buzz/b9222db494758c3e536b8e2011032ba7cec86daa/pr-8912--01-prefilled.png" width="200"> | <img src="https://raw.githubusercontent.com/block/buzz/b9222db494758c3e536b8e2011032ba7cec86daa/pr-8912--02-created.png" width="200"> | <img src="https://raw.githubusercontent.com/block/buzz/b9222db494758c3e536b8e2011032ba7cec86daa/pr-8912--03-reply.png" width="200"> | <img src="https://raw.githubusercontent.com/block/buzz/b9222db494758c3e536b8e2011032ba7cec86daa/pr-8912--04-unavailable.png" width="200"> | Before this PR, the app had no handler for `buzz://agent/new`, so the link did nothing. A separate widget test covers a link that needs Builderlab sign-in first: once sign-in lands, a setup saved for that account blocks the card, which is never fetched. Removing the registry reload fails it, as does removing the busy-Agents guard for the journey step above. ### Before merge - [x] Human live check waived under the repository owner's standing testing exception. In its place, agent-driven full-app runs exercised the flow end to end: the iPhone SE device run and the simulator demo above (a real card's share page, **Add to Buzz**, the prefilled form, Create and a reply from the agent).

Tom Brow	61b8455a3c	fix(mobile): open unjoined channels from links and search results (#8923) ... Tapping a `#channel` link to an open channel you haven't joined showed "Channel could not be opened", because a tap could only open a channel already in the local list. A search hit had the same gap: it did nothing when its channel wasn't in the loaded list, for example when the open-channel directory failed to load or hadn't loaded yet. Both taps now go through one resolver. It looks in the loaded list first, then reads the channel's own metadata, as `buzz://` deep links already do. - An open channel you haven't joined opens in preview ("Join this channel from Manage to participate"). - A private or withheld channel stays closed and shows "Channel not found here". - A failed lookup shows "Could not open the channel". So does a missing channel when the channel list failed to load, since it may be one you belong to. The resolver also guards two cases: - A second tap during a slow lookup doesn't open the channel twice. - A lookup that finishes after you switch community or identity, or after you moved to another page, opens nothing and doesn't block a new tap. Fixes AIDA-2324 and AIDA-2286. [#8764](https://github.com/block/buzz/pull/8764) already made search load the open directory, which fixed the common search case, so the search part here covers the remaining fallback. ### Before: a link to an unjoined open channel fails https://github.com/user-attachments/assets/c39cf0db-8098-4010-993e-cf664230c809 ### After: the same link opens the channel in preview https://github.com/user-attachments/assets/1422e70f-39c5-4598-8232-efad190b3413 ### Validation - Added tests: - A table-driven channel-link journey with four rows: an unjoined open channel opens, a withheld channel and a private channel show "Channel not found here", and a failed lookup shows "Could not open the channel". Each row double-taps during a gated lookup and asserts a single lookup and a single push. Failure rows then tap again to show the lock is released. - A lookup that settles after the user opened another page pushes nothing. - Search journeys: a message hit opens its unlisted channel (including after the channel list failed to load), or explains why it can't ("Could not open the channel" when the list failed). - Taps whose lookup will be discarded don't block the next tap: after a community switch away and back, or from another page after the first page closed. Each row fails if its part of the tap lock or the connection fence is removed. - I reverted the production files to `main` once and confirmed every new test fails there. - The full mobile suite and `mobile-check` pass. - I ran it on an iPhone 18 Pro simulator (iOS 27), signed in to Builderlab with an account that isn't a member of the open channel `#speed-tests`. - A link to that channel shows the error toast on `main` and opens a preview with this change (videos above). - A search hit in that channel opens it with this change. On `main` it also opens, through [#8764](https://github.com/block/buzz/pull/8764)'s directory load. - Not covered by tests: waiting for a channel-list load still in flight, a short guard I checked by reading the code. - The human app-test step doesn't apply (Tom's standing exception for mobile client changes). buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz>	2026-11-02 12:55:59 -08:00

Two lookups used the raw, still-escaped destination: - **Bubble segmentation** (`bubble_segments.dart`): an attachment link such as `[voice.mp4](https://…/voice\_note.mp4)` missed its imeta entry and stayed inside the text bubble, even though the link builder rendered it as an attachment. The fix unshields the URL before the lookup. - **Trailing image gallery** (`extractTrailingImageGallery` in `message_gallery.dart`): with two or more trailing images, an escaped destination kept its backslash, so the carousel loaded the wrong URL and lost the imeta alt text. The fix unescapes the destination the same way as the label beside it. Its callers in `message_media_avatar.dart` and `message_skeleton_body.dart` get the fix too. This gap was already on main. ### Validation - The existing `attachments stay outside bubbles and text order is preserved` journey now uses an escaped destination with a plain imeta URL. The existing carousel journey now has one escaped image destination and taps it by its plain URL. Each fails with its fix reverted. - `flutter analyze` is clean and the full mobile suite passes (4151 tests). - Limitation: no simulator run. Both changes are key lookups, and the widget journeys exercise the rendered layout. The full-app run for the surrounding escape handling is recorded in #8925. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-02 11:18:10 -08:00
Logan Johnson	2fd5c122e8	fix(mobile): load earlier edits to thread replies when a thread opens (#8870) ... ## Summary In the mobile thread view, if a reply was edited before you opened the thread, the reply showed its original text and no "(edited)" marker. An edit that arrived while the thread was open worked. The thread `/query` asked only for message kinds. The channel window carries edits, reactions and deletions (aux events) only for top-level messages, so an earlier edit to a reply was in neither result. The thread query now sends `include_aux: true`, as desktop does (`buzz-app` `src/features/relay/threads.ts`). The relay already supports this on the `depth_limit` thread route: it returns the aux events for the root and every reply, plus deletions of those (`crates/buzz-relay/src/api/bridge.rs`, `bridge_thread_aux`). A relay that ignores the flag gives the same result as before. The relay sends a page's rows (at most 200 reply-marked events, of any kind) before that page's aux events. It also repeats the root's aux on every page. So `fetchCompleteThread` treats the leading run of events reply-marked into this thread, other than reactions and NIP-09 deletions, as the page's rows. Only rows count toward a page, move the cursor and feed the reply cache. A reply-marked huddle event still fills a page, and a reply-marked reaction never becomes a reply. A reply-marked edit of the root in the repeated aux can follow a short final page's rows and look like a full page, so the scan also stops when the next cursor does not advance. The thread-summary scan (`fetchCompleteThreadReplies`) still asks for replies only and pages exactly as on `main`. ### Related issue Found during the emulator testing of https://github.com/block/buzz/pull/8863. ### Testing - `just mobile-check`, `just file-size-check` and `just mobile-test` pass. - `thread_replies_provider_test.dart` adds two tests. The first checks that the query sends `include_aux` and that an edit made before the thread opens folds into its reply. The second covers pagination: a reply-marked huddle row filling a page, a reply-marked edit that is a row on one page and aux on the others, a reply-marked reaction that stays aux, 200 reply-marked reactions after 199 replies (one query), 200 reply-marked root edits after a short final page (the progress guard ends the scan), an edit reply-marked into another thread that stays aux, and that the summary scan doesn't send `include_aux`. It fails if any of these is removed: the reaction/deletion exclusion, the root check, the 200 cap, the progress guard, or the separate row and aux id sets. - `channel_detail_page_test.dart` adds a journey: it opens `ThreadDetailPage` with the real thread query and a fake relay session that sends the reply's earlier edit only when `include_aux` is set. It checks the edited text, that the original text is gone, and the marker. It fails when the flag is removed or when the provider drops aux. - Android emulator (AVD, debug build) against a local relay. Morty posts "Who can review the release notes?", Demo User replies "I can, after lunhc" and then edits the reply to "I can, after lunch", all before the thread is opened. These shots come from the first revision of this branch. The pagination changes after it give the same result for a one-page thread like this one. | Before (unfixed: the #8863 build) | After (this branch) | Live edit while the thread is open | | --- | --- | --- | | <img src="https://raw.githubusercontent.com/block/buzz/4daefdf9a427c66dd80edcc59ee664c1da63824c/pr-8870--thread-before.png" width="300" alt="Before: original reply text, no marker"> | <img src="https://raw.githubusercontent.com/block/buzz/4daefdf9a427c66dd80edcc59ee664c1da63824c/pr-8870--thread-after.png" width="300" alt="After: edited reply text with (edited)"> | <img src="https://raw.githubusercontent.com/block/buzz/4daefdf9a427c66dd80edcc59ee664c1da63824c/pr-8870--thread-live.png" width="300" alt="Live edit while the thread is open"> | Before, the thread shows the original reply text with no marker.

Tom Brow	54ca2a3cc6	fix(mobile): render Markdown backslash escapes (#8925) ... Mobile showed Markdown backslash escapes literally. A message linking a channel as `[\#buzz-mobile](buzz://channel/…)` rendered as `\#buzz-mobile`, and `\[text\]` rendered as LaTeX math. gpt_markdown has no backslash escapes. Outside code, each escaped ASCII punctuation character is now held as a stand-in (an invisible word joiner plus the character's fullwidth form) before parsing, so no other syntax (links, emphasis, mentions, channel tokens, math) matches it. A new inline component and the link and image builders restore the original character. The inbox/search preview builder already handled escapes this way; its helpers moved to a shared `markdown_escapes.dart`. Two edge cases found in review are covered: shielding runs after trailing-gallery extraction so carousel URLs and labels stay as authored, and a bare link no longer takes a trailing backslash into its destination. Codex review added: escaped backticks stay literal instead of opening code, authored word joiners are not mistaken for stand-ins, Buzz URL punctuation peeling keeps a trailing backslash, gallery semantic labels drop escapes, the trailing-backslash peel is linear and reruns after delimiter stripping, an escaped `\<url>` is not treated as an autolink, `~~~` fences are skipped like backtick fences, an autolink containing `\` keeps it in both label and destination, and the stand-ins use fullwidth characters so the one gpt_markdown fallback that shows raw text (multi-line strikethrough) still reads right. Later review: fence detection looks back only over blanks and `>` markers, so it stays linear on long lines (security review) and treats an unclosed fence inside a quote or list as code, like the renderer (Carl). Behavior change: `\(x\)` and `\[x\]` now show as `(x)` and `[x]` instead of math, per CommonMark. Desktop (buzz-app) doesn't render math either. `$…$` math is unchanged. ### Validation - Added tests: a `MessageContent` table covering escapes in prose, bold, link labels (HTTP and `buzz://channel`), fenced and inline code (left literal), a bare link ending in `\`, and escaped backticks, authored word joiners and fullwidth characters, a `~~~` fence, a multi-line strikethrough, `<https://example.com/a\>`, a Buzz URL ending in `.\`, an emphasized bare URL ending in `\*`, an escaped `\<url>`, and a trailing image gallery with escaped labels (including its semantics label), in plain and bubble layouts. Each row also asserts no stand-in reaches visible text or semantics. Reverting any one of these fixes fails it. - `flutter analyze` is clean and the full mobile suite passes, except for 11 `notification_toggle_test.dart` tests. Those fail locally on the Studio at the CI-green a3964ab as well, so they are environmental and unrelated to this change. A 256 KiB regression test covers the linear fence scan, and it fails on the earlier code. - iPhone 17 Pro simulator (iOS 27) signed in to the internal community: loganj's original message now shows `#buzz-github-prs` and `#buzz-mobile`. - Full-app run on [a3964ab](a3964ab08c): debug build on a fresh iPhone 17 Pro simulator (iOS 27), signed in to the internal community with live data. Covered the #buzz-github-prs timeline (long linked lists, bare URLs, mentions, reactions, thread summaries), a thread view, Inbox previews (the shared preview helpers), a DM with a bare link and a channel link, and search results. Everything rendered as before apart from the fixed escapes, with no stray stand-in characters. Limitations: debug build, iOS only, no gallery or code-block messages were in the visited history (the widget tests cover those), and a 165-second recording was taken but GitHub can't take it through our upload script. Two quirks seen are pre-existing and unchanged here: a bare link absorbs a trailing comma, and search shows raw Markdown for messages over 512 characters. <details><summary>Full-app screenshots</summary> | Channel | Channel (scrolled) | Thread | | --- | --- | --- | |  |  |  | | **Inbox** | **DM** | **Search** | |  |  |  | </details> ### Before / after Before (production build, reported):  After (this branch, same message):  🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: studio <dc2fc481343672df31a689840c09299972e704dac592e0da6f18486646a7ee3e@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-02 10:35:54 -08:00
