fix(desktop): bound and cancel invite-handoff join policy discovery
A receipt-less buzz://join claim first discovers the relay's join policy through the webview fetch path, which had no deadline, no body cap, and no way to cancel. A relay whose /api/join-policy blackholed, trickled, or streamed an oversized body left onboarding on "Accepting your invite…" forever, and cancelling did not stop the download. The webview branch of getJoinPolicy now matches the native fetch_join_policy bounds: one 15 s deadline covers the headers and the whole body, and the body is capped at 4 MiB while it streams (a larger declared Content-Length fails up front). A timeout surfaces as "The community's join policy took too long to load.", which the claiming stage shows with Retry. getJoinPolicy takes an optional AbortSignal, and useClaimInvite aborts the pending lookup when its transaction is cancelled, replaced, or unmounted. The existing transaction fence still drops any late settlement. The useClaimInvite jsdom suite gains a journey with a suspended /api/join-policy: no error at 14.999 s, a retryable timeout at 15 s with zero claims, then a retry that claims once against a policy-free relay. The single cancel test becomes a cancel/reopen table. Each row asserts the lookup's signal is aborted and that a late policy response neither claims nor moves the cleared or replacement transaction. A getJoinPolicy test rejects both a streamed and a declared body over 4 MiB. Removing the abort, the fence, the timer, or the cap each fails its test.

fix(mobile): allow relay-sized join policy responses
Mobile read GET /api/join-policy through the generic 64 KiB hosted response cap, but the relay allows each policy markdown document up to 256 KiB and Desktop accepts a 4 MiB policy response. A self-hosted relay with a valid policy over 64 KiB was joinable on Desktop but failed on Mobile with an invalid-response error before consent could render, and every retry hit the same cap. boundedHttpResponse and readJoinResponse now take a maxBytes that defaults to the existing 64 KiB hostedResponseMaxBytes. Only loadJoinPolicy opts into the 4 MiB cap that matches Desktop, so the accept-policy, claim, and other hosted replies keep their limit. The reader accumulates into a BytesBuilder so a multi-MiB body is not held as a list of ints. The invite consent journey now serves a policy over 64 KiB and asserts that Mobile loads its full terms and claims only after native acceptance. The hosted-admission "oversized policy" row used bare whitespace, which failed as invalid JSON whatever the cap was. It now sends valid JSON padded past 4 MiB. A focused test serves a relay-sized policy alongside an accept-policy reply over 64 KiB: the policy reaches consent, the reply is rejected, and no claim is sent.

fix(mobile): show invite sheet while join policy loads
The deep-link dispatcher awaits InviteJoinNotifier.prepare before it presents the invite sheet, and prepare awaited GET /api/join-policy. On a slow or blackholed relay, opening an invite did nothing visible until discovery finished or hit the 30 s request deadline. prepare now returns once the pending invite and host are established and loads the policy in the background. A new isLoadingJoinPolicy state renders a "Loading community policy…" row (the spinner owns the announcement) and keeps Join disabled until the policy is shown or confirmed absent. A per-load token fences the result: a re-prepare, reset, or claim supersedes the load, so a stale success or failure cannot overwrite a claim that confirmJoin started, e.g. from the iOS native sheet. confirmJoin still re-reads the policy before it claims. The dispatcher gains a table with a suspended /api/join-policy response. Both rows assert that the host, an enabled Cancel, the loading row, and a disabled Join are visible before the GET resolves, with no claim. The policy row then claims once with the app-minted receipt after age confirmation and acceptance. The absent row claims once without a receipt after Join. The provider claim journey now claims while discovery is still suspended, then fails that discovery and asserts the join stays successful.

fix(desktop): ignore deep-link policy receipts for native invite consent
Anyone holding an invite code can mint a join-policy receipt from the public accept-policy endpoint, so a receipt carried by a buzz://join link does not prove this app showed consent. Desktop persisted that receipt into the onboarding transaction (and kept a retained same-relay receipt on resume), which made useClaimInvite skip policy discovery and claim without the native consent stage. startCommunityOnboarding now drops receipts for deep-link-join transactions, both when creating one and when resuming a same-relay transaction, so the invite-consent stage is the only source of the receipt a link join claims with. The deep-link drain no longer forwards the link's receipt. The useClaimInvite jsdom table gains rows for a link-supplied receipt and a retained same-relay receipt. Each row asserts the flow reaches invite-consent with zero claims, then claims once with the app-minted receipt after native acceptance.

fix(mobile): show organization sign-in after pairing (#9028)
## Summary Show organization sign-in after pairing. The community chooser closes before it waits for content when the organization session needs sign-in. A long press on **Scan a QR code** reveals the pairing-code option. ### Related issue Related to [#9001](https://github.com/block/buzz/pull/9001) and [#9009](https://github.com/block/buzz/pull/9009). No duplicate PR found. ### Testing On an iPhone 17 Pro simulator, paired with the Block relay using a build that includes both related PRs. The app showed **Sign in** on Home. Completing sign-in remains to be verified.

fix(mobile): show progress after pairing QR scans (#9009)
## Summary After a pairing QR scan, the app shows connection progress until code entry or a connection error. A WebSocket handshake that remains pending stops after ten seconds. Cancel is available until storage starts. It resets pairing and restores the entry form. Pasted codes remain available after an error or cancellation. Back navigation stays blocked during identity transfer and storage. Cancel on Send identity to desktop returns to Settings, so another attempt starts through the authorization step. ### Related issue Related to [#9001](https://github.com/block/buzz/pull/9001), which covers organization sign-in after identity transfer. This change covers the earlier connection stage. ### Testing A simulator build with PR #9001 completes identity transfer and saves the community. The community chooser still blocks organization sign-in. [PR #9028](https://github.com/block/buzz/pull/9028) covers that step. 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. Test a failed connection and retry. In Settings, open Send identity to desktop, start a recovery connection, and cancel. Check that Settings appears and another attempt asks for authorization. Camera recognition speed and the reported intermittent phone network failure remain unverified.

fix(desktop): hold a deep-linked message against bottom settles (#8742)
## Summary A product fix for the most frequent unfixed desktop E2E flake, `message-target-highlight.spec.ts:79`. A deep-linked message now holds its place against bottom settles until the reader scrolls. This is one of six PRs split from the reviewed `flakey-tests` branch (siblings below). - **Runs:** it failed in all 7 main runs whose SHA carries every earlier flake fix (40969965981, 40970005965, 40970053997, 40980258899, 40980404335, 40980513346, 40983029157). It also failed in 26 jobs since those fixes landed, on main and on PRs #8235, #8239, #8241, #8666 and #8680. Only the two cases that pick `mounted[2]` fail: "same channel, row loaded off screen" (15 jobs) and "other channel, row further up" (11 jobs). The target scrolls in and flashes, then the timeline lands on the newest message. `stillOnScreen` at :179 reads false (twice it was `flashedOnScreen` at :153). ### Cause The failure videos (run 40983029157, Smoke shard 6) show that the thread panel opening is a precondition, not the trigger. A later floor report moved the target: `TimelineMessageList`'s `onScroll` reported within 32 px of the bottom, during or after the older-page load that only a `mounted[2]` target sets off. `onVirtualizerAtBottomStateChange(true)` reset the anchor to at-bottom. Then the split-panel settle, the viewport-resize settle or the next append settle pinned the timeline to the floor. Which Virtua layout pass emits the floor report is still unidentified. ### Change Accepting a virtual route target sets `targetHoldRef` in `useAnchoredScroll`. Only the two `targetMessageId` paths set it, via `holdTarget`. The public `scrollToMessage`, which the oldest-unread pill and find-in-channel use, doesn't hold, and it replaces any earlier hold. While the hold is set: - The split-panel and viewport-resize settles are skipped. - A floor report still updates `isAtBottom` and the new-message count, but keeps the message anchor, so live appends don't settle either. - A commit that changes the newest message sets `isAtBottom` false and clears `virtualizerAtBottomRef`. It adds the rows after the previous newest one to the new-message count. So the "Jump to latest" / "N new messages" pill still appears for rows below the fold (Review-Proven Rule 6). A history page that fills the gap below a cold target raises no pill, and neither does deleting the newest message. - Viewport reflow re-centres the target through `virtualScrollToMessage`. It runs from the resize observer and when the split panel opens or closes. The hold is released by reader scroll input: a wheel, a touch drag, a pointerdown on the scroller itself, or a scroll key. Those listeners already cancel bottom intent in `useVirtualizedBottomSettle`, and this PR shares them as `listenForReaderScroll`. Jump to latest, the reader's own send and a channel change also release it. A release at the floor restores the at-bottom anchor, so the timeline follows live messages again. `onTargetReached` does not release the hold. ### Known limits - Programmatic scrolls (focus moves, `scrollTop` writes) don't release the hold, but a find or unread-pill jump replaces it. A resize after such a scroll re-centres the target. - ChannelPane's composer-height settle still calls `scrollToBottom` within 32 px of the floor, which releases the hold. - Live messages that arrive under a hold near the floor aren't followed until reader input, Jump to latest or the reader's own send. The pill shows them, with their count. - Under the hold, only rows after the previous newest message count. A same-second row that sorts just ahead of it raises no pill until a later row lands. - Agent review raised two optional gaps, and scrolling recovers from both: - If the previous newest message is deleted and a new row arrives in the same deferred commit, 0 rows are counted. - A thread reply sent with "also send to channel" doesn't arm the bottom intent, so it shows as "1 new message" instead of being followed. ### Related issue None found. ### Testing `useAnchoredScroll.lifecycle.test.mjs` replays the CI sequence: accept a route target, clear it, open the split panel, report the floor, resize and append a live message. It asserts no bottom settle, a re-centre on the panel opening and on the resize, and the pill on the append. Further cases cover: - each release path; - a find jump on a held timeline; - a descendant pointerdown keeping the hold; - a gap-fill page and deleting the newest message, neither of which raises the pill. The split-panel and viewport-resize policy tables each gain a held row. Mutations were run over the lifecycle file and both policy tables (29 tests, all pass intact). Each of the 20 mutations fails at least one test: | Mutation | Tests that fail | |---|---| | Hold never set (the old behaviour) | 12 | | Split-panel settle ignores the hold | 13 | | Viewport-resize settle ignores the hold | 13 | | Floor report resets a held anchor | 12 | | No split-panel re-centre | 12 | | No viewport-resize re-centre | 12 | | Reader input doesn't release the hold | 6 | | Held append raises no pill | 2 | The commit message lists the other 12, each failing 1 or 2 tests. `pnpm typecheck` and `pnpm check` pass. All 46 tests in the files that import the touched modules pass. Only hosted CI can show whether the spec now holds in Smoke shard 6 and in Flake Check's repeats, because Playwright was not run locally. It also has to show that `scroll-history.spec.ts` and the other timeline specs keep bottom-follow working. Pushed with `git push --no-verify`, because the pre-push suites fail when the laptop is under load. ### Readiness and human check An agent review of the combined `flakey-tests` branch (b432453af) found no blockers. This changes desktop app behaviour, so it needs a human in-app check before `buzz-review-completed` is added. Suggested check, in `just dev` against a channel with a few pages of history: 1. Open a message link (a mention or search hit) to a message several screens up, once in the same channel and once from another channel. The message should flash and stay on screen after older history loads, including when the thread panel opens or closes, or the window is resized. 2. With the target still held, have someone post in the channel. The timeline stays put, and the pill reads "1 new message". 3. Wheel-scroll to the bottom, or click Jump to latest. The next message that arrives is followed. ### Siblings - #8739 ci: Hermit fetch deadline and sccache fallback - #8740 test(relay): thread_window aux-page hold and `api::media` Postgres tests - #8741 test(mobile): RunnerTests title fade and alert wait - #8743 test(desktop): four specs racing scroll settles and focus - #8744 test(desktop): five settle classes and remote-owned-mentions 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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.

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.

feat(relay): match verified names in profile search (#9019)
## Summary `POST /profiles/search` only matches kind:0 `name` and `display_name`. In communities that publish NIP-FI verified profiles, a person's surname or directory username often appears only in their relay-signed kind:30382, so typeahead cannot find them by it. - Where the community advertises verified profiles, the search also matches the `display_name`, `username` and `full_name` tags of each current kind:30382 head signed by the relay key. - Verified names need a trailing prefix of at least three characters, as in NIP-50, so a short prefix doesn't make the relay rank every verified head. kind:0 keeps one-character typeahead. Lookups from heads to `events` also match `created_at`, so Postgres prunes to one partition. - Results are paged by person. Each person returns their current kind:0, when they have one, then their current kind:30382, when they have one, whichever matched. A person is ranked by their best match across both sources, using the existing tiers. - NIP-11 `federated_identity.public_profile` gains `searchable: true`, so clients can rely on the response instead of a separate kind:30382 read. - Migration `0081` adds a GIN expression index over the head's name tags on `nip_fi_profile_heads` (built-in `jsonb_path_query_first` and `to_tsvector`, no new functions). The table holds one row per verified person. Like `0078`, the migration builds the index only while the table is empty; populated databases prebuild it with `CREATE INDEX CONCURRENTLY` (`docs/profile-search.md`), and the migration then checks it is valid and has the expected definition. Compatibility: the request schema is unchanged. Existing clients that keep only kind:0 events work as before and also find people who match only by verified name. Trust stays pinned to the relay `self` key; the event shape follows NIP-85 user assertions, but discovery is relay-advertised rather than kind:10040. ## Testing - `buzz-search` Postgres integration: new `profile_names_match_verified_names` covers forged-key heads, replaced heads, other communities, people without kind:0, per-person grouping, paging, and words split across sources; the existing profile-name tests pass unchanged. The test fails when the author filter is inverted. - `buzz-relay` end to end in enforce mode: `profile_search_matches_verified_names_where_advertised` publishes through the real writer and finds the person by surname only where verified profiles are advertised. - Desired-state and migration index definitions match. - `profile_names_use_verified_name_index` asserts the search scans the new index. Migration `0081` checked against an empty table, a rerun, a populated table without the index (raises), the documented concurrent prebuild, and an index with a different definition (raises). - Latency, 50k people each with a kind:0 and a verified head, release build, local Postgres, best of 5, 30 people per page: 11–22 ms with verified names versus 1–8 ms kind:0 only. `EXPLAIN` shows a bitmap scan on the new index. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Kalvin Chau <kalvin@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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>mobile-v0.27.0-rc.20 |

fix(mobile): show newly created remote agents in the new-chat picker (#9030)
After creating a remote agent on mobile (for example in onboarding), the agent doesn't appear in the Solo **New chat** agent picker. Mentioning it in a channel, or restarting the app, works around this. The picker's agent list (`meAssistantsProvider`) is loaded once and kept for the app session. Creating a remote agent publishes its owner registration (kind 30177), and Beekeeper publishes the agent's attested profile, but nothing told the cached list to reload. So the new agent stayed missing until something unrelated (a relay reconnect or an app restart) rebuilt the list. With this change, the list reloads whenever this device publishes or removes a remote agent registration, using the controller's existing `registrationRevision`. Agents created on another device still show up only after the next reload, as before. ### Validation - Added test: `Solo agent choices reload after this device creates an agent` (hosted build) creates an agent through the real `RemoteAgentController.create` path and checks that the picker's list includes it. It fails without the fix (list stays empty) and passes with it. - Full mobile suite passes, and so do the hosted-build `shared`, `features/agents` and `features/channels/me` suites. Analyzer and format are clean. - Automated simulator pass on the fixed build (signed in to a Builderlab-hosted community): opened **New chat**, the picker listed all 7 agents, picked one, opened an existing Solo chat and the Agents page, then reopened the picker and it still loaded correctly. Human testing is waived per the repository's mobile testing exception. - Limitation: I didn't create a real remote agent on the simulator, because its Builderlab web sign-in stalled. The create → picker path is covered by the added test. 🤖 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> |

docs(nip-fa): define agent grant, assertion and revocation routes (#9015)
Adds wire formats to NIP-FA for agent keys acting under an owner-authorized grant. - **Agent keys**: the owner authorization is a NIP-OA `auth` tag the adapter verifies against the owner's bound key; adapters accept empty conditions and refuse conditions they don't support. An adapter that operates an agent itself may keep its grant internally. - **Agent grant** (`POST /v1/nip-fi/agent-grant`): an RFC 8693 token exchange of the owner's adapter session (as `subject_token`), the agent key's NIP-98 proof in `Nostr-Authorization`, and the NIP-OA tag for an opaque agent grant. Defines neutral token types `urn:nostr:params:oauth:token-type:nip-fa-session` and `urn:nostr:params:oauth:token-type:nip-fi-agent-grant`. An invalid or unacceptable `subject_token` is `400 invalid_request` per RFC 8693 §2.2.2. Grant lifetime is adapter policy. Enrollment replaces earlier grants; an agent key's owner never changes, and a revoked key cannot be enrolled again. - **Agent assertion** (`POST /v1/nip-fi/agent-assertion`): the grant as Bearer plus the agent's NIP-98 proof; same body and checks as `/v1/identity/assertions`, returning `nip-fi-agent+jwt`. `exp` is not capped by any session, and clients check `iss` against the grant's issuer. `401 invalid_grant` discards the grant; an unauthorized relay is `403 authorization_denied`, as on the human route. - **Agent revocation** (`POST /v1/nip-fi/agent-revoke`): the owner's session revokes one agent by pubkey and invalidates its grants and disconnects it through the NIP-FI admin disconnect API; single-field form, 1024-byte limit, idempotent. - Proofs are single-use on the grant and assertion routes. - **NIP-FI assertion transport**: the agent-grant `subject_token` is the one exception to Bearer-only session transport. - **Security considerations**: origin, redirect and logging rules for agent grants. NIP-FI is unchanged: its "Agent keys" section and out-of-scope list are consistent with these routes. --------- Signed-off-by: Will Pfleger <wpfleger@block.xyz> |

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> |

feat(relay): log reads, logins and connections on access target (#8376)
🤖 Adds an access log for relay reads, logins, connections and HTTP requests on the dedicated `buzz_relay::access` target. It writes to stdout, not `audit_log`, so reads never take the audit advisory lock. The log is shaped for volume: one line per HTTP request, one line per WebSocket read, and one line per WebSocket connection. ## Lines per operation | Operation | Lines | |---|---| | HTTP request on a matched route | 1 (`http`), except the skip list below | | HTTP request matching no route | 1 (`http`, `route="<unmatched>"`) at status 400 and above, otherwise none | | WebSocket connection | 1 (`close`, carrying the login) | | WebSocket `REQ` / `COUNT` / NIP-AR sync | 1 each (`req` / `count` / `sync`), plus the `buzz_ws_reads_total` counter | | WebSocket NIP-42 login | 1 (`auth`) per decided or cut-off attempt, capped after the decision as below | | Audio login | 1 (`auth`, at its final admission check) | | WebSocket `EVENT` | 1 (`Event ingested`, not on the access target) | ## HTTP requests One middleware, `http_access_log`, writes every HTTP line. It sits between `track_metrics` and `http_trace_layer`, so rebuilt errors, body-limit refusals and localhost refusals all reach it. It writes the line when the response is ready, which is not proof the body was delivered. A request dropped before then logs `request=aborted` at WARN with no `status`. - Every line carries `route` (the matched route template, never the raw path), `peer_addr` when the listener has one, `status`, `time_to_response_ms` and `http_method` (the HTTP verb). The verb stays on the line itself because the `http.request` span is absent under an access-only filter and when a pending request is dropped. - Handlers record what they learn on the request's `AccessSlot`: the login (`method`, `pubkey`, `pubkey_verified`, `community`), the decision, the filter summary, and the route's own fields. The decision is `outcome` (`success` / `denied` / `failed` / `challenged`) with a fixed `reason`, or `undecided` when the route recorded none. A refusal is final: a later admission doesn't replace it, so a replayed NIP-98 proof that verifies and is then refused logs `failed` / `nip98_replay`. - `outcome` describes the login. What the route did is in `status` and the route's fields: a rejected `/events` write logs `outcome=success` with `status=400`, `accepted=false` and its `reject_reason`. - Route fields: - `/query` and `/count`: the filter summary and `result_count`. An incremental `/query` response (`{changes:[...]}`) counts its changes, removals included. Artifact reads record their summary before the query runs, so a read dropped mid-query keeps it. - `/events`: `accepted`, `kind`, `event_id`, and on a refused write the parse `category` / `line` / `column` or a fixed `reject_reason` (such as `invalid` or `restricted`), never the ingest message. - Invite mint: `invite_id`, `expires_at` and `max_uses`. Invite claim: `joined`. - Admin feedback attachment reads: `feedback_id` and `attachment_sha256`. With `BUZZ_ADMIN_AUTH=disabled` they log `method=network_trusted` with no key, and Host or Origin refusals log their fixed reason. - Every other route logs only the login fields. - No field can hold an invite code, a token, or a Blossom read hash. Media routes log the `/media/{sha256_ext}` template. - Skip list: NIP-11 and other non-upgrade requests on `/`, `/info`, `/.well-known/nostr.json`, `/health`, `/_liveness`, `/_readiness`, and the SPA and static files the relay serves when enabled (web assets, invite landing pages, git web pages, the admin bundle) at any status. Successful WebSocket upgrades (101) log no `http` line. Refusals before the upgrade on `/` and the audio path log one, with the status actually sent. - Routes that aren't Nostr-key logins (the command-token disconnect endpoint, the workflow webhook, the git server's internal callback) log `outcome=undecided` with no key. - Dev-mode `X-Pubkey` requests log `method=x_pubkey`, `pubkey_verified=false`. - A successful `/query` or `/count` that returned nothing (`result_count=0`) logs at DEBUG: on staging, 93% of `/query` lines were empty polls. Denied, failed, aborted and error reads, reads with no `result_count`, writes and logins keep their levels. - Other successful lines and git's credential-less first request (`challenged`, with its 401) are INFO. Refusals, statuses of 400 and above, and aborted requests are WARN. In Enforce mode the line records the remapped status (for example 403). Denial bodies and headers are unchanged. ## WebSocket reads - `REQ` / `COUNT` / `sync` lines carry `pubkey`, `conn_id`, `sub_id`, the filter summary, the outcome (`served` / `denied` / `aborted` / `error` plus a fixed reason), and `events_queued` (REQ and sync) or `count` (a COUNT that counted). A `REQ` is `served` only once its EOSE is queued to the client. A read logs WARN only when it ends in `error`. `served`, `denied` and `aborted` are INFO, since `aborted` means the read ended before completing: the client disconnected or sent CLOSE, a same-ID `REQ` replaced it, or the session was cancelled. - A NIP-AR sync subscription writes its `sync` line when its initial set completes, not when live delivery ends. Its summary is the registered live filter (kinds and channels, never artifact predicates), and `events_queued` counts the initial set. - `REQ` lines stay at INFO even when empty at EOSE, because the subscription can still deliver live events later. - Filter summary, shared with HTTP `/query` and `/count`: `kinds`, channel ids, authors and `p` values each list the first 10 distinct values. The exact `kind_count` / `channel_count` / `author_count` / `p_count` (summed per filter) appears only when the list is `*` or shows fewer values than the filters held. A dimension that any filter leaves open logs `*`. `since` / `until` / `limit` take the widest bound and are absent when any filter leaves them open, so no field understates what the read covered. `ids` is a count only. NIP-50 search logs `search: true`, never the text. Only well-formed channel ids and pubkeys are listed. An artifact read's summary uses only the standard dimensions of each raw filter, so artifact predicates and client-defined tags (such as `#1`) are never logged. The summary is skipped when the access target is off. Under `=warn`, every WARN line, HTTP or WebSocket, still carries it. - Per connection, only the first 16 reads that are refused before they run (`auth_required`, quota, concurrency, overload) or denied are logged. The rest are counted as `reads_suppressed` on the close line. A refusal that arrives after the close line has been written, from a read still running when the client left, logs its own line, so every refusal is either logged or counted, never both. Served reads are never capped. ## WebSocket read counter `buzz_ws_reads_total{type="req"|"count"|"sync"}` counts every parsed `REQ`, `COUNT` and NIP-AR sync frame before admission, exported at zero from startup. It is a metric, so it counts at any `RUST_LOG`, including production's current `error`. ## WebSocket logins A NIP-42 login writes one `auth` line when it is decided. A successful login logs INFO `outcome=success` at its commit point, decided under the connection's close-reason lock, so a disconnect racing the login (session expiry, admin disconnect, revocation, ban or roster removal) either wins, and the login logs no success, or loses and closes the connection right after the success line. A refused or failed login writes one WARN `auth` line with `outcome`, a fixed `reason` from the shared `AuthReason` code set, `pubkey` and `pubkey_verified`. Root WebSocket `auth` lines carry `peer_addr`. AUTH frames after the login is decided are capped at 16 per connection, and the rest are counted as `auth_suppressed`. An attempt cut off by close or session expiry logs `aborted`. Audio logins log one `auth` line at their final admission check. ## Connections The close line is the connection's only line. It is owned by the upgraded socket, so it is written exactly once however the connection ends: a normal close, a refusal while checking the community is active (`refused=not_admitted`), the connection limit (`refused=connection_limit`), or the handler being dropped. It carries `conn_id`, `community`, `peer_addr`, `duration_ms`, the login, `events_queued` / `bytes_queued` (frames the writer accepted and flushed, not client delivery), and the two suppression counters. ## Error text - Database errors log as `DbError::kind()` (SQLSTATE or variant), including the command-executor event insert. Search errors, on both read paths and in the search-cancel task, log as `SearchError::kind()` / the same SQLx classifier. Workflow database and webhook errors log as their codes, since webhook URLs can be secrets. - Git NIP-98 failures log a fixed code. Git subprocess stderr moved to DEBUG because hook output can contain message text. ## Operator notes `.env.example` documents the target, its `event` values (`http`, `auth`, `req`, `count`, `sync`, `close`), the skip list, the levels, and how to turn it down: `buzz_relay::access=warn` keeps refusals, errors and aborted HTTP requests, and of WebSocket reads only those that end in `error`, and `=off` drops everything. It also lists the removed lines: `NIP-42 auth successful/failed`, `WebSocket connection established/closed`, `event=connect`, `HTTP bridge request`, `Event ingested via pipeline`, `relay invite minted`, `relay member added via invite`, `admin feedback attachment read`, and `addr` (now `peer_addr`). JSON lines no longer repeat the current span as `span`, since `spans` already ends with it. A line logged under an explicit `parent:` span loses that parent's fields. The default OTel export filter sets `buzz_relay::access=off`, so access lines aren't exported a second time as span events. `peer_addr` is the TCP peer. `BUZZ_CLIENT_IP_HEADER` optionally names a request header (for example `cf-connecting-ip` behind Cloudflare or `x-real-ip` behind nginx, matched case-insensitively). When set, `http`, `auth` (root and audio), `close` and connection-limit lines also log `client_ip`: the rightmost comma-separated entry of the header's last field, only if it parses as an IP address. It never replaces `peer_addr`, and it is only trustworthy when every request arrives through a proxy that overwrites the header. --------- Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

feat(relay): push per-community storage usage to kgoose (#8714)
### Why?
To bill hosted communities for storage in Orb, kgoose needs
per-community storage usage. The relay already computes it in a daily
snapshot, but nothing delivered it anywhere.
## Summary
- Adds opt-in `BUZZ_STORAGE_USAGE_URL`. When it is set, one
leader-elected relay pod checks every 5 minutes for a new storage
snapshot and POSTs it to kgoose's `POST /v1/buzz/storage-usage/record`
(squareup/cash-server#144285) in consecutive batches of up to 50
communities until every community is sent.
- Each batch is `{measured_at, communities: [{community_host,
storage_bytes, storage_objects}]}`. Active communities with no stored
bytes are reported as zero, and re-sends are safe because kgoose bills
each community once per UTC day.
- Retries on 408, 429, 5xx, and transport errors. No migration;
documented in `docs/storage-accounting.md`. kgoose authenticates the
relay as the `buzz` mesh service, so the relay needs mesh egress to
kgoose-builderbot.
### Related issue
None found. Complements #7899 (snapshot history in the DB). Receiving
endpoint: squareup/cash-server#144285.
### Testing
Unit tests cover batching, retry and reject handling, zero-filling, and
a real HTTP delivery that checks the exact kgoose request body. A
Postgres-gated DB test covers the new reads. End to end, a local relay
delivered to a fake endpoint once per new snapshot.

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. Resolve the inherited text style and platform bold override before measuring, and use that same style for rendering. 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. To verify: enable system Bold Text, open a channel with a single-participant thread, and confirm “12 replies” remains complete; repeat with enlarged text and toggle Bold Text off. No physical-device validation is claimed.

fix(relay): stop logging unmapped-host NIP-FI denials as server failures (#8997)
## What this does In enforce mode, a request whose Host maps to no community gets NIP-FI's `authorization_unavailable` 503 (`docs/nips/NIP-FI.md`, Rejection and privacy table). tower-http's default classifier treats every 5xx as a failure, so each of these requests also logs a `tower_http::trace::on_failure` error. That line has no host or path, only `503` and `latency: 0 ms`. When a scanner probes a host this relay doesn't serve, it produces thousands of these lines in a minute, and they trip error-rate alerts even though nothing is down. This PR keeps the wire response the same and stops counting these denials as server failures: - `nip_fi_core::community_denial` builds the same `http_denial` response. When the Host is confirmed unmapped, it adds an internal `UnresolvedHost` response extension. Extensions never reach the wire, so the NIP-FI denial contract ([FI-TRACE-DENIAL-ORACLE]) still holds. - Each site that turns a community-resolution failure into a denial now uses it: - the router guard (`nip_fi_assertion_guard`) - the WebSocket upgrade (`check_nip_fi_at_upgrade`) - HTTP admission, for routes the guard exempts (`Stage::Community`) - The HTTP trace layer now uses `RelayResponseClassifier`. It treats marked responses as expected and keeps tower-http's 5xx-is-failure rule for everything else. Other 503s still log as failures. That includes an unavailable JWKS key source on a mapped host, `deny_protected`, a stale snapshot, and a failed database lookup. ## Why not return 4xx for unmapped hosts? NIP-FI.md maps "community/Host resolution unavailable" to 503, and `nip_fi_enforce_unmapped_host_is_503_before_verification` pins that ruling. Changing the status would be a spec change. This PR only changes how the relay logs these denials. ## Database community source With `BUZZ_NIP_FI_COMMUNITY_SOURCE=database`, a not-found host and a failed lookup (DB error, timeout, shed waiter) return the same denial class. The marker is set only when the host is confirmed unmapped: a missing Host, a non-bindable host, or a live negative-cache entry. Resolver outages stay unmarked and still log as failures. With the `env` source, every resolution failure means the host is unmapped, so it is always marked. ## Testing - `nip_fi_enforce_unmapped_host_is_503_before_verification` (guard, root upgrade, audio upgrade) and `enforce_unmapped_host_is_503_before_nip98_and_verifier` (HTTP admission) now also assert the marker. Mutation check: removing the guard marker turns the router test red. - New `nip_fi_mapped_host_dependency_503_is_not_marked_unresolved`: a mapped-host 503 from an unavailable key source is unmarked and still classified as a failure. - New `relay_response_classifier_skips_only_unresolved_host_denials`: covers marked 503, unmarked 503, 500, 200 and 401. - New `only_confirmed_unmapped_hosts_are_marked_as_expected_denials` (database source, all three sites): a negative-cached host and a non-bindable host are marked; a bound host whose lookup fails is not. Mutation check: marking every database failure turns it red. - `cargo clippy -p buzz-relay --all-targets -D warnings` is clean, and the pre-push `rust-tests` lane passed. - Local relay, before and after. Setup: enforce mode, `RUST_LOG=error`, one mapped host, JWKS unreachable on purpose. Both builds got the same requests: | Request | Status (both builds) | `on_failure` errors before | after | |---|---|---|---| | Unmapped host, 4 protected paths | 503 | 4 | 0 | | Unmapped host, WebSocket upgrade on `/` | 503 | 1 | 0 | | Mapped host, no assertion | 401 | 0 | 0 | | Mapped host, well-formed JWT, JWKS unreachable | 503 | 1 | 1 | | Unmapped host, `/assets/` path and `POST /api/invites/claim` | 404 | 0 | 0 | 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> Co-authored-by: opus <f038cc09b32a776e7d95b65c267e9d851777ee2b6cdbd46a48edba01b1d10ebd@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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> |

feat(loadgen): model desktop clients and large-community shape (#9005)
## Summary
The load generator models every community as many small open channels,
and every human as a bare WebSocket client: four REQs, a little history,
then nothing until the run ends. Large deployments don't look like that.
They have thousands of people in a few communities, a handful of very
wide channels, and some people in hundreds of channels. Their desktop
clients also make most of their relay requests over HTTP and on timers.
This PR adds opt-in scenario knobs for both, so a run can reproduce that
shape and compare the desktop client before and after its recent
request-volume fixes.
Every new key defaults to the previous behavior. Existing scenarios
parse, assign members and run exactly as before.
### Shape
| Key | Default | Meaning |
|---|---|---|
| `shape.private_channels` | `false` | `seed` creates channels private
and adds every member with kind:9000 before posting history. Members are
the humans and agents assigned to each channel up to the largest ramp
step, plus the hot thread's root and authors. Events carry up to 100
members each and run `seed_concurrency` at a time. A rerun adds nobody
new, and any member the relay refuses fails the seed. |
| `shape.wide_channels` | `0` | The first K channels of each community
are wide channels. |
| `population.wide_member_fraction` | `0.0` | Share of humans that join
every wide channel on top of their own. |
| `population.wide_activity_share` | unset | Share of its typing,
messages and reactions a member of the wide channels sends there; the
rest goes to its regular channels. Unset keeps the uniform pick, which
sends half of a 3-wide/3-regular member's traffic to the wide channels
and makes fan-out, not reads, the bottleneck. |
| `population.tiers` | `[]` | `[{ fraction, channels }]`: that share of
humans joins `channels` channels instead of `channels_per_member`. |
Assignment is deterministic by global index, so `seed` and every
`--shard` agree without coordination. With no wide channels and no tiers
it is the old assignment, and a test pins that.
### Desktop clients (`[desktop]`)
| Key | Default | Meaning |
|---|---|---|
| `fraction` | `0.0` | Share of humans that run the desktop model
instead of the basic human. |
| `mode` | `"current"` | `legacy` is the client before its volume fixes;
`current` is after them. |
| `windows`, `threads` | `3`, `1` | Open channel windows and threads,
which are refreshed on connect. |
| `tick_secs` | `60` | Recovery tick period. |
| `backstop_secs` | `900` | `current` only: each tick item (subscription
replacement, roster, unread repair) waits this long since it last ran. |
| `renewal_secs` | `0` | Identity renewal period. `0` disables renewal,
and the first renewal is jittered. |
A desktop human keeps the basic human's presence, typing, messages and
reactions. What it adds:
- **Cold start.** It reads NIP-11 and opens its profile and membership
subscriptions. Its channel subscriptions are batched per mode:
- up to 10 channels: one replaying batch;
- `legacy` with more than 10: one per-channel batch per 10 channels;
- `current` with more than 10: a live-only subscription per 2048
channels, plus replays of 10 that are closed at EOSE.
It also makes the app's HTTP reads: roster, channel names, sidebar,
profiles, statuses, emoji, read state, unread repair, reminders, window
catch-up plus notices for each window, and root plus thread page for
each thread. A window catch-up follows the cursor in the relay's window
bounds (kind 39006) for up to five older pages, until the bounds say
history is exhausted.
- **Route establishment.** `legacy` makes every read as it connects.
`current` reads NIP-11, names and sidebar up front, and the rest as each
subscription reaches EOSE, by its replay outcome. A replay of 500
events, a missed deadline, or the live-only batch over 10 channels is a
cut, and so is a route the previous connection never caught up. Only an
EOSE catches a route up: one recovered after a missed deadline cannot be
resumed or carried by the next connection.
- A continuous profile route skips its read (unless one is owed).
- A continuous membership route only repairs unreads, without the
read-state snapshot, unless a snapshot read failed since; then it runs
the full repair.
- A cut global reads in full, and channel routes always recover windows
and threads.
- **Ticks and renewals.** These follow each mode:
- `legacy`: every tick replaces subscriptions and rereads roster and
unreads, and a renewal is a full reconnect;
- `current`: tick items wait for the backstop, measured from the last
replacement, the last successful roster read, and the last full unread
repair. A failed roster read, unread repair or read-state snapshot is
owed and retries on the next tick; snapshot debt is tracked apart from
repair debt, so a repair without the snapshot never settles it. A
renewal carries its routes: nothing is read while every replay keeps
continuity, and once one is cut every route establishes as on a
reconnect. With more than 10 channels the live-only batch is always cut,
so the channels recover and unreads are repaired, but globals are not
reread.
- **Reporting.** Each request type is its own op (`desktop_roster`,
`desktop_unread`, `desktop_replay_eose`, …).
- **Bounds.** At most 4 REQs set up at once, with a 10 s EOSE timeout. A
tick replacement that misses it is closed, the batch it would have
replaced stays, and the next tick retries. At most 6 HTTP reads in
flight, with a 30 s timeout. A read that comes due while the same read
is running or queued is not added again, and each read leaves the
running set as soon as it settles, so a failed read can retry while a
slow one is still under way. Connects and failed sessions back off. A
stop abandons pending EOSE waits without counting them as failures.
- **Not modeled.** The app also establishes channel routes when a tick
replacement reaches EOSE; the generator does not.
`perf/LOADGEN.md` documents the knobs and the model.
`perf/scenarios/local-desktop.toml` is a short local example with every
knob on.
## What got simpler
- `human()`'s schedule loop (presence, typing, messages, reactions,
session end) moved into one `Activity`. The basic and desktop humans
share it, so neither client duplicates the schedule. The basic human's
random draw order is unchanged.
- Membership stays in one place. `member_channels` remains the single
assignment function, and `channel_members` derives from it rather than
from a second formula, so seeding and the clients can't drift apart.
The desktop model is a new concept: about 1,420 lines of model in its
own module, plus about 1,300 lines of tests. Everything else goes
through existing seams: `Stats`/`Op`, `connect`, `Backoff`, `observe`,
`roots` and `Net`.
Identified debt, not fixed here: CI's `test-unit` runs `buzz-test-client
--lib` with the filter `loadgen::`, so the five crate-root `tests::` in
`lib.rs` (relay message parsing, auth and text event building,
`collect_until_eose`) never run in CI. That gap predates this PR, which
doesn't touch `lib.rs`.
## Testing
- `cargo fmt --check`, `cargo clippy -p buzz-test-client --all-targets
-- -D warnings`, and `cargo test -p buzz-test-client` (plain parallel):
84 lib tests pass.
- Wide activity: a seeded `Rng` over 100k picks gives each share within
1%, and an unset share makes the identical draws to before. A run
against a loopback relay checks that a human's typing lands only in its
regular channels at share 0, and only in its wide channels at share 1.
- Scenario: validation of every new key; deterministic wide-channel and
tier assignment that honors the fractions; `channel_members` inverts the
assignment up to the peak; the default assignment is unchanged; the
shipped scenarios parse.
- Seed: with private channels, a fake relay sees the following, in
order:
- every 9007 before any 9000, and every 9000 before any post;
- owner signatures;
- ≤100 members per event;
- exactly the expected members per channel;
- posts authored by channel members.
A refused member fails the seed, and open channels add nobody.
- Desktop: request planning, window bounds validation, route
establishment, and tick and owed-read rules are unit-tested. End-to-end
tests drive clients against loopback WS and HTTP fakes. The WS fake
replays a planned number of events per subscription and can delay an
EOSE or drop a connection. The HTTP fake answers window pages with
relay-signed bounds, an older aux event and equal-timestamp rows,
refuses unknown cursors, and can fail a read once. They check:
- exact cold-start counts per op for `legacy` and `current` at 5 and 25
channels;
- a window catch-up sends the head, then exactly the bounds' cursor
(`until` + `before_id` of the last row, not the older aux event), and
stops when the bounds say history is exhausted even though that page
came back full;
- after a `current` renewal, 499 replayed events everywhere read nothing
over HTTP; 500 on the channel batch adds channel recovery plus a covered
unread repair; 500 on membership adds roster, read state, unread and
reminders plus channel recovery; 500 on profiles adds profiles, statuses
and emoji plus channel recovery and a covered repair;
- after a dropped connection, complete global replays read only NIP-11,
channel recovery and a covered repair; truncated ones reread both
globals in full;
- with renewals shorter than the backstop, read-state snapshots still
recur at the backstop;
- a tick replacement past its EOSE deadline is closed, the old batch
stays, the next tick replaces it, and one batch wire stays open;
- a failed roster and unread read retry on the next tick, and successful
reads do not run again;
- a failed roster read retries on the next tick while an unrelated slow
read is still running;
- after a failed snapshot, a continuous membership establishment before
any tick still reads the snapshot;
- a route whose EOSE missed its deadline is recovered, and after a
renewal with a complete replay it is recovered in full again rather than
carried;
- `legacy` ticks replace batches (new REQ before the CLOSE of the old
one) and reread;
- `current` ticks do nothing until the backstop, then replace live-only;
- `legacy` renewals are full reconnects;
- `current` renewals carry small sessions without rereading globals or
channels, and recover channels in large ones.
Each of the nine review-fix tests was checked against a mutant that
restores the old behavior, and every mutant fails its test.
- Smoke: a local relay with Postgres and Redis. I ran `seed` twice, then
`run` of `local-desktop.toml` (60 s) once per mode.
- Both seeds were accepted (780 of 780 posts each), including private
channels and memberships for 340 people. Neither run aborted, no client
was cancelled, and no op recorded an error.
- Each run used 18 desktop clients:
| op | `current` | `legacy` |
|---|---|---|
| `desktop_live_eose` | 266 | 483 |
| `desktop_replay_eose` | 24 | 0 |
| `desktop_roster` | 72 | 289 |
| `desktop_read_state` / `desktop_unread` | 72 / 99 | 289 / 289 |
| `desktop_profiles` | 18 | 73 |
| `desktop_nip11` | 18 | 73 |
| `desktop_window` | 372 | 596 |
Window reads are below the first smoke (406 and 1086) because catch-ups
stop where the relay's bounds say history is exhausted, rather than
paging while pages came back full. They are above the previous revision
(179 and 470) because each read now leaves the running set as soon as it
settles, so a channel recovery is no longer dropped as a duplicate of a
read that already finished inside a still-running batch.
- The first smoke caught two relay contract mismatches that the fakes
had missed:
- top-level window pages need `before_id` with `until`;
- the read-state snapshot answers with an object.
Both are fixed, and the fakes now enforce both.

fix(relay): apply kind 5 / 9005 deletions atomically (#8944)
## Summary Kind 5 and 9005 deletions now store the event and soft-delete their targets in one transaction. Before this PR the deletion committed first. The target soft-delete ran afterwards as a best-effort side effect, and a failure there was only logged. Resending the deletion then returned `duplicate:` without retrying. A crash between the two commits had the same result. Either way the relay accepted a deletion while its target stayed live. The bridge `include_aux` closure still compensates for those rows. Its second hop returns deletions of the reactions and edits it found, so clients can cancel them. This PR keeps that hop, because rows already torn this way can't be repaired by a resend: - Ingest rejects events more than 900 seconds from server time. - Clients don't resend deletions that were accepted. - During a rolling deploy, old pods keep writing torn rows until they are replaced. Dropping the hop waits for a follow-up, once existing torn rows have had a verified repair and no old writers remain. ### Changes - **Atomic deletion.** Kind 9005, and kind 5 with `e` targets, go through `Db::insert_deletion_event`, driven by `side_effects::persist_deletion`. The write stores the event and its mentions, soft-deletes the targets and updates their thread counters. It follows the existing `persisted_atomically` path used for workflow deletion and kinds 9000/9002. - A failure stores nothing and rejects the event, so the client can resend. - A resend of a stored deletion inside the ingest window soft-deletes any target still live and is dispatched as inserted. It doesn't repair older rows. - Live 39005, reaction-table cleanup and the 9005 system message still run after the commit and stay best-effort. - Kind 5 deletions of `a` coordinates stay a side effect. - **Closure unchanged.** The channel window and legacy thread-reply paths keep both hops, and the docs (`docs/bridge-channel-window.md`, `docs/nips/NIP-CW.md`) are unchanged. ### What got simpler Deletion no longer has a window where the event is accepted but not applied. `handle_standard_deletion_event` is now only the `a`-coordinate path. Target planning and soft-delete for `e` targets live in one place, `persist_deletion`. ### Follow-ups (not in this PR) - Repair the existing torn rows: soft-delete the live targets of stored kind 5 / 9005 `e` deletions and fix their thread counters. Then drop the closure's deletion-of-aux hop. - Hop 1 still probes every partition once per row id. A partition bound or the indexed `reactions` table would cut that. ### Related issue N/A, found while investigating relay database CPU. ### Testing - `torn_deletions_still_cancel_live_targets_in_both_windows` (bridge Postgres) stores kind 5 and 9005 deletions without soft-deleting their reaction and edit targets. It queries the channel window and the legacy thread path with `include_aux`, without a resend, and asserts each live target comes back with its deletion. - `insert_deletion_event_target_failure_stores_nothing_and_resend_applies` (buzz-db Postgres) uses a trigger to make the target's soft-delete fail. It asserts nothing is stored and the target is unchanged, then that a resend applies both. - `insert_deletion_event_resend_repairs_a_live_target` (buzz-db Postgres): a resend repairs a deletion stored without its target's soft-delete, and a further resend changes nothing. - `failed_target_soft_delete_stores_nothing` and `resent_deletion_repairs_a_live_target` (relay Postgres) cover the same two cases through ingest, for kinds 5 and 9005. - `test_channel_window_rows_overlays_and_exact_multiple_exhaustion` (`e2e_nostr_interop`, Relay E2E lane) deletes its reaction and asserts the reaction leaves the closure. - Blox: fmt, clippy (`buzz-db`, `buzz-relay`, `buzz-test-client`), and the `buzz-db` and `buzz-relay` Postgres lanes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(db): drop a superseded head's mention rows with it (#8948)
## Summary
Replacing a replaceable or addressable event soft-deletes the previous
head, but its `event_mentions` rows stayed behind. Only the hard-delete
kinds (read-state and mesh status) removed theirs, in a separate
statement. No mention-index read (`#p` filters and feeds) returns a
soft-deleted event, so those rows are pure cost: every `#p` read walks
them and throws them away.
A kind:39002 roster republish leaves one dead row per channel member, so
a large channel piles them up with every join. Relay-emitted replaceable
lists with p-tags do the same.
The statement that retires the old head now deletes that head's mention
rows as well, through a data-modifying CTE over `RETURNING id`, on all
three supersede paths:
- the relay's kind:39002 roster writer
(`LockedMemberSnapshot::replace_member_event`)
- `replace_addressable_event` (kind 0/3/10000–19999, including the
relay-signed kind:13535 list)
- the NIP-33 parameterized path
Because the CTE covers every row the retire statement touches, a
coordinate that somehow had more than one live row also gets cleaned up.
The shared `superseded_with_mentions_sql!` macro sits at the crate root
so all three mention-indexing replacement paths use the same statement.
The kind:13534 membership-list and push-lease writers also retire heads,
with a bare `UPDATE`, but neither indexes p-tags, so they leave no
mention rows.
## What got simpler
The hard-delete special case (`if hard_delete_superseded { DELETE FROM
event_mentions … }`) is gone. Both retire statements go through one
macro, so a head and its mention rows leave together on all three paths.
## Not in this PR
- Mention rows already left behind by earlier supersedes.
`docs/database.md` rules out data backfills in migrations, so these get
cleaned up out of band, in batches.
- Other soft-delete paths (NIP-09 deletion, moderation, channel deletion
retiring its 39000–39002 events) also keep mention rows. They are
low-volume, and are noted here as identified debt.
## Tests
`superseded_heads_drop_their_mention_rows` (pg) has one table row per
supersede path: the member-snapshot roster writer (lock, replace,
release), the addressable path, the NIP-33 path, and the two NIP-33
kinds that are hard-deleted (NIP-RS read state and mesh status). In each
case the old head keeps zero mention rows and the new head is indexed.
Soft-delete rows check that the old head stays soft-deleted, and
hard-delete rows check that it is gone. Reverting the macro, any single
call site, or the hard-delete statement alone fails this test.

perf(db): bind the channel scope as one array (#8946)
## Summary Event reads scoped to a set of channels pushed one bind parameter per channel: `channel_id IN ($5, $6, …)`. This applies to a viewer's access scope, which the relay adds to every REQ and `/query` without an `#h`, and to explicit multi-value `#h` filters. As a result, the SQL text depended on the viewer's channel count, and every count was a separate prepared statement. That caused two problems in production: - **Re-planning on every call.** A connection rarely reused a cached plan for these reads, so Postgres planned each one again. With no `since`, the plan covers every `events` partition. For `#p` mention reads (the `event_mentions` join), planning took far longer than executing the query. - **Hidden cost.** Monitoring that groups by statement split one query into one row per channel count, so its total cost never showed up in a single place. This PR binds the set as `channel_id = ANY($n)`, so one statement serves every channel count. On a production replica, the same query prepared with `ANY($5)` moved to Postgres's cached generic plan by its sixth run. Planning time dropped to near zero, and that plan was no slower than the custom one. ## What changed - `push_channel_scope` in `crates/buzz-db/src/store/event.rs` builds the channel-scope predicate as one array bind. - `build_query_events_sql` and `count_events_sql` each had their own copy of this block. Both now call the helper. - Semantics are unchanged: - Access scope still keeps channel-less global events. - Explicit `#h` still matches only the requested channels. - An empty set still means "no channels". ## What got simpler Two duplicated 20-line blocks became one helper. The statement count for channel-scoped reads no longer grows with channel count. ## Generic-plan exposure These statements were already persistent prepared statements, so a cached generic plan was always possible whenever the connection's statement cache held one. This change makes that reuse consistent; it doesn't introduce generic plans. Tag-value reads (`has_tag_values`) still run unnamed, as before. Plain (non-`#p`) access-scoped reads stay on custom plans. A production replica, with a viewer in hundreds of channels, ran the plain page read repeatedly under the default `plan_cache_mode`, and every run used the custom ordered index scan. Postgres estimated the generic plan as far more expensive, and when forced, it was orders of magnitude slower. Postgres switches only when the generic plan is no costlier than the average custom plan, so it never chose this one. The generic plan's cost comes from the `LIMIT` and `kind` values it can't see, not from the array length, and the per-arity `IN (…)` statements had the same blind spot. ## Tests - `channel_scope_sql_does_not_depend_on_channel_count` (unit): for the `#p` join and plain reads, for access scope and explicit `#h`, in both the page SELECT and the COUNT, the SQL for 1 channel equals the SQL for 40 channels. It also checks that the SQL uses `ANY(` and that global rows are retained only for access scope. - `channel_scoped_mention_reads_share_one_prepared_statement` (Postgres): on one connection, access-scoped `#p` reads with 1, 2 and 3 channels leave exactly one prepared `event_mentions` statement. With one mention per channel, one global mention, and one in an unscoped channel, every scope of 0–3 channels, with and without globals, returns and counts exactly its own rows. - The existing scope semantics tests still pass: - `access_scope_is_applied_before_historical_page_limit` - the explicit multi-channel `#h` page and count test - Mutation: reverting the helper to one bind per channel fails both new tests. ## Identified debt (not in this PR) - `get_last_message_at_bulk` still builds an `IN (…)` list per channel. It's a separate, lower-volume statement. - Superseded versions of replaceable roster events (kind 39002) keep their `event_mentions` rows. On large channels, a viewer's roster mention rows grow with every membership change. That's a follow-up. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

feat(relay): record NIP-FI enforce denials at parity with shadow (#8974)
## What this does
In enforce mode, NIP-FI denials used to be returned without a reason
counter or a log line. This PR records enforce denials with the same
`WouldDeny` reasons, label sets and log fields as shadow. **Admission
behavior does not change**: statuses, close codes and frame order are
all the same.
- **`buzz_nip_fi_enforce_total{route,stage,outcome,community}`**: the
same shape as `buzz_nip_fi_shadow_total`, including an `admit`/`admit`
stage, so `1 - admit/total` is the enforce denial rate. Each socket or
HTTP request gets exactly one verdict.
-
**`buzz_nip_fi_enforce_session_end_total{route,reason=expired|revoked,community}`**:
once per admitted session.
- **`buzz_nip_fi_enforce_strict_proof_total{route,outcome,community}`**:
the outcome of the proof check that actually decided the request.
Nothing is verified twice.
- **Log lines** `nip-fi enforce deny` and `nip-fi enforce session end`
(info, `mode="enforce"`, from `buzz_relay::nip_fi_shadow`). Shadow's
`nip-fi shadow would-deny` gains `mode="shadow"`. Neither mode logs
admits.
### How each verdict is recorded once
- **Sockets (root, audio).** `EnforceSession` moves Pending →
Admitted(pubkey) → Ended under one std mutex, and records inside the
lock with no awaits.
- Root admits at its AUTH commit; audio admits at its join commit.
- A refusal for a non-NIP-FI reason retires the session without a
record. Audio retires it before rollback.
- A deadline the effect gate sees before the expiry worker is claimed at
that seam.
- **Ends.** Revocation and expiry are recorded only by the terminal
transition that wins (`publish_authorization_denied`), and only while
the socket isn't already cancelled. A community close or cancellation
that wins first records nothing.
- **HTTP.** The router guard scopes each enforced request with one
verdict. An agent token's verdict is deferred to the end of the request:
- the first owner-decided refusal is the verdict, otherwise the request
was admitted;
- membership rechecks, batches, Git success and early returns each count
once.
- **Owner provenance** comes from the decision itself
(`BanVerdict{outcome,source}` from one `restriction_state` read), with
no rereads.
- Reasons: `owner_banned`, `owner_ban_unavailable`, `not_stored_owner`,
`owner_link_unavailable`.
- When the agent's own ban read fails and there's a token owner, the
result is `owner/unavailable`, as shadow records it.
- A ban or failed restriction read that ingest catches on `POST /events`
after membership passed replaces the request's admit with `owner/denied`
when the owner's row decided the ban, or `owner/unavailable` on a failed
read. An agent's own ban is not recorded as its owner's.
## Shadow-to-enforce map
| Shadow signal | Enforce counterpart |
|---|---|
| `buzz_nip_fi_shadow_total` denials: upgrade, guard, HTTP admission,
AUTH pairing, deny set, stale binding | `buzz_nip_fi_enforce_total` with
the same stage/outcome, plus a `nip-fi enforce deny` line |
| `buzz_nip_fi_shadow_total` owner stage: ws, audio, http | the same,
from the original decision: root/audio ban seam and owner link; HTTP
`enforce_membership`, smart Git, Git settings, buzz/v1 ban reread |
| `buzz_nip_fi_shadow_total` `deadline/session_deadline` (pending) |
`EnforceSession::expire`, from the worker's winning terminal or the
effect gate that saw it first |
| `buzz_nip_fi_shadow_total` admit |
`buzz_nip_fi_enforce_total{stage="admit",outcome="admit"}`, one per
socket or request |
| `buzz_nip_fi_shadow_session_end_total{reason=expired\|revoked}` |
`buzz_nip_fi_enforce_session_end_total`, same labels |
| `buzz_nip_fi_shadow_strict_proof_total` |
`buzz_nip_fi_enforce_strict_proof_total`, from the deciding check (a
rejection is the route's 403, or 401 when the proof is missing) |
| `buzz_nip_fi_shadow_disconnect_total{admin,accepted}` |
`buzz_nip_fi_disconnect_total` (`api/nip_fi.rs:160`) |
| `buzz_nip_fi_shadow_disconnect_total{admin,propagation_failure}` |
`buzz_nip_fi_disconnect_propagation_failures_total`
(`api/nip_fi.rs:180–185`) |
| `buzz_nip_fi_shadow_disconnect_total{admin,capacity}` |
`buzz_nip_fi_disconnect_capacity_rejections_total`
(`api/nip_fi.rs:196–201`) |
| `buzz_nip_fi_shadow_disconnect_total{cross_pod,capacity}` |
`buzz_nip_fi_cross_pod_capacity_exceeded_total`
(`api/nip_fi.rs:433–434`) |
| `buzz_nip_fi_shadow_disconnect_total{cross_pod,poison}` |
`buzz_nip_fi_cross_pod_shard_poison_total` (`api/nip_fi.rs:442–443`) |
| `buzz_nip_fi_shadow_disconnect_total{cross_pod,lag}` |
`buzz_nip_fi_disconnect_lag_total` (`main.rs:1596–1602`) |
The enforce series was renamed from `buzz_nip_fi_enforce_denied_total`
to `buzz_nip_fi_enforce_total` when it gained the `admit` stage.
## Tests
Infra-free, in the `test-unit` lane:
- `state::enforce_end_is_recorded_only_by_the_winning_terminal`: root
scan, audio scan and deadline, each against a community close or
cancellation first and FI first.
- `nip_fi_http::enforce_strict_proof_records_the_deciding_check_once`:
pass and reject, and no record when cardinality refuses.
-
`nip_fi_shadow_session::audio_owner_link_refusal_shares_roots_seam_and_reasons`:
calls the shared owner-link helper with route `audio`, not a huddle
socket.
- The existing shadow, upgrade, router and HTTP enforce tests.
Postgres lane:
-
`handlers::auth::enforce_root_auth_records_owner_refusals_from_one_decision`:
clean admit then `expired` through the real expiry worker; banned token
owner, banned stored owner, other stored owner and a failed ban read;
authorization reads counted from the decision only.
-
`handlers::auth::enforce_root_deadline_seen_by_the_gate_first_is_recorded_once`:
both orderings.
- `audio::handler::enforce_join_commit_is_the_audio_admission`: drives
the join-commit seam directly, not a huddle socket or the expiry worker:
committed then expired; archived with an expiry held inside the
rollback; gate-first deadline.
-
`api::bridge::token_owner_reaches_membership_on_every_nip_fi_http_route`:
one verdict per request on every NIP-FI HTTP route, including sidebar,
read-state, Blossom and Git, for an owner ban, a stored-owner conflict
and a clear owner.
-
`api::bridge::token_owner_ban_reread_is_the_fixed_nip_fi_denial_on_http`:
own ban, owner ban and unavailable at the reread, on sidebar and Git
settings.

fix(ios): mint NIP-FI assertions in the notification extension (#8982)
Organization relays that enforce NIP-FI (federated identity) require a `Nostr-Federated-Identity` assertion on `/query`. The iOS notification service extension signed its `/query` with NIP-98 only, so the relay answered `401` and every push from an enforcing organization relay showed the generic "You have a new message." body. The app already mints these assertions in Dart from its organization account session, but that session lives in the app's own keychain, and assertions last minutes, so a cached one is useless by the time a push arrives. This change lets the extension mint its own: - **App:** whenever the organization `BuilderlabAccountClient` adopts or clears its session, the app writes or deletes a device-only keychain item in the group it already shares with the extension. The item holds the organization origin, the session credential and the organization's exact relay hosts (from `BUZZ_ORGANIZATION_RELAYS`). Builds without an organization never write it. - **Extension:** for a community whose relay host is one of those exact hosts, `BuzzRelayAssertionIssuer` requests an assertion from the organization issuer (`/api/goose/v1/buzz/identity/assertions`, session credential plus NIP-98 with the community's account key, the same request the app makes), checks it was issued for that key, and caches it in-process until 30 seconds before expiry. Both `/query` paths (message lookup and sender/channel enrichment) send it. Other relays get no header and never see the session. - Signing out awaits removal of the shared copy and fails if removal fails; each restore that finds no session retries the removal. - If issuance fails or the user is signed out, the extension sends the query without the header and the relay refuses it, which keeps today's generic fallback. Not covered here: relay-hosted avatars on enforcing relays still load without the assertion (the notification text and title are unaffected), hosted Builderlab communities, and Android. ### Validation Added tests: - `testOrganizationRelayQueriesCarryMintedAssertion`: against a stub relay that answers `401` without the assertion, two organization pushes resolve with message body and sender name from a single issuance, a non-organization relay gets neither the header nor the session, and after sign-out the notification falls back. Removing the header from the query path makes this test fail. - `testOrganizationAssertionIssuanceFailuresSendNoHeader`: refused, wrong-key, expired and header-injection responses produce no header. Subdomains and other ports of the organization relay host are never sent the session. - `builderlab_account_test.dart`: the shared copy follows exchange, restore and clear; a failed removal fails sign-out, and the next restore retries it. Focused existing validation: the full BuzzPushKit suite, the hosted Dart tests, `flutter analyze`, and an iOS device build of the app and extension. Not yet validated: a live push from the Block relay on a device. ## Before merge Live device push test: waived by Tom (2026-11-03). 🤖 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> |

Enable incremental artifact reads on every relay (#8975)
## Why Compatible clients need incremental artifact reads for local collections on every Buzz relay. ## What Expose incremental artifact reads and capability discovery on every Buzz relay. ## How Serve incremental queries through the existing authentication and authorization checks. Keep the existing work budgets and the separate WebSocket sync capability. The HTTP test verifies capability discovery and a successful incremental query. ## Risk The relay starts no additional background work. Clients that use incremental reads consume database capacity. The net database load is not yet measured. Serving writers must maintain the modification timestamps. ## Testing Read-only SQL checks on November 3, 2026 verify the prerequisites below. Each database records successful migrations 76–78. All five required columns have the expected types, defaults, and nullability. All five indexes have the expected definitions and are valid, ready, and live. | Deployment | Schema and indexes | Running timestamp writers | | --- | --- | --- | | Production `bb-block` | Pass | `f6f6d9a` includes PR 8523 | | Production `bb-public` | Pass | `f3a7bab` includes PR 8523 | | Staging `bb-block` | Pass | `b4509de` includes PR 8523 | The checked columns are `artifact_heads.modified_at`, `artifact_revisions.modified_at`, `artifact_revisions.source_channel_id`, `channel_members.sync_modified_at`, and `communities.artifact_policy_modified_at`. The checked indexes are `idx_artifact_revisions_artifact`, `artifact_heads_modified`, `artifact_heads_channel`, `channel_members_sync`, and `artifact_revisions_moves`. At commit `62b26ad`, all 21 NIP-11 tests and the HTTP capability test pass on Linux with PostgreSQL 17 and Redis. The HTTP test checks capability discovery and a successful incremental query. All required push hooks also pass. No manual testing. Human confirmation remains pending. ## Bigger picture [Client PR 1507](https://github.com/block/buzz-app/pull/1507) uses the advertised capability for local artifact sync. Existing deployments receive this behavior when they deploy the relay version that includes this PR. Generated with Codex --------- Signed-off-by: Daniel Rouleau <drouleau@squareup.com> |

fix(relay): send membership notices on channel delete, moderation kick and moderation DM (#8977)
Related: [buzz-app#2215](https://github.com/block/buzz-app/pull/2215) ## Problem A connected client learns about membership changes from kind:44100/44101 notices and then re-reads its channel list. Three relay paths changed a member's channel list without sending a notice, so clients only caught up on their periodic full read: - **Channel delete (9008):** no member was told. - **Moderation kick:** the kicked member wasn't told, and the channel's 39000/39002 discovery wasn't refreshed, so it still listed them. - **Moderation DM:** a new, existing or hidden moderation DM didn't surface live. ## Change - **Channel delete:** `soft_delete_channel_capturing_members` (buzz-db) reads the channel type and active members under deletion's existing membership lock, in the same transaction. A join either commits first and is included, or waits and is then refused. After the commit, discovery cleanup and cache invalidation, the relay sends a type-tagged 44101 to each captured member in a spawned task, eight at a time, outside any lock. The 9008 OK doesn't wait for them, and the task is started before the `channel_deleted` system message is emitted, so a system-message failure can't drop them. An already-deleted channel sends nothing. `soft_delete_channel` keeps its signature and delegates. - **Moderation kick:** `apply_kick_live_side_effects` refreshes 39000/39002 after the removal fence commits, then sends 44101 to the kicked member. If the refresh fails, it returns the error before the notice, so the moderation driver's existing mutation-marker recovery retries. If the channel was deleted since the kick, there's no roster to refresh: it removes the channel's discovery events and treats that as converged, so the action still finalizes. The removal/re-add fence and the re-added early return are unchanged. - **Moderation DM:** `send_moderation_notice` drops both participants' cached channel sets on every pod (`invalidate_membership`), as opening a DM does in `command_executor::handle_dm_open`, so the read the notice prompts includes the DM. After clearing `hidden_at`, it republishes the recipient's NIP-DV kind:30622 visibility snapshot (clients filter the sidebar on it), then emits discovery, then sends 44100. It sends the notice on every delivery, tagged `moderation_source` with the delivery's source id, so two deliveries in the same second each get their own 44100. The content JSON is unchanged. A failed snapshot or discovery returns an error, so the outbox retries. - **Ordering guarantee:** each notice is sent after its change is committed and readable on the relay instance that sends it. Ordering across relay instances, and other instances' cached channel sets, are best-effort, the same as for existing membership notices. - A failed notice delivery is logged and never undoes the change, like the existing 9001 path. There's no new retry system. ## Tests - `membership_notice_postgres_tests.rs`: one journey per path. A `#[cfg(test)]` barrier at the point a notice is signed parks the producer, keyed by recipient. While it's parked, the test reads the channel list (and, for the DM, the 30622 snapshot) as a client would on receipt. The barrier can also pin a notice's `created_at`. - The DM journey pins both deliveries to the same second, hides the DM through the real kind:41012 path between them, and checks what a client sees: a live 44100 for each delivery, with distinct ids, then a channel-list read that lists the DM and a visibility read that no longer hides it. - `moderation_dm_notice_follows_a_cached_channel_list` warms the recipient's channel set with a read before the DM exists, then checks the read on receipt of the notice lists the DM. - `soft_delete_captures_members_at_its_serialization_point` (buzz-db): a join and then a delete queue behind a held membership lock. The delete must return the joiner, and a later join is refused. - `crash_recovery_finalizes_kick_after_channel_deleted` (admin): commits a kick, deletes the channel, then runs the recovery worker. The action finalizes, and the member's `removed_at` is unchanged, so the removal doesn't run again. Each ordering test fails when its prerequisite is moved or removed: the kick notice ahead of the roster refresh, the delete notices ahead of discovery cleanup, the DM without the snapshot republish or the cache drop, the DM notice without its source tag (the second notice coalesces), and the member capture outside the lock. The recovery test fails if a deleted channel's `ChannelNotFound` propagates. No spec files change. This reads a channel delete as removing every member under the existing `NOSTR.md` notice promise. --------- Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

fix(ios): stop repeating an old message in push notifications (#8973)
## Context Pushes from the gateway carry no event reference (`crates/buzz-push-gateway/src/model.rs`), so the iOS Notification Service Extension resolves each push by querying the user's NIP-PL lease filters and showing the newest matching message. Any push whose trigger wasn't the newest message (a reaction, an edit or deletion, a community query that failed, or several pushes arriving for one message) showed that same newest message again. Tom saw one message notify four times over three hours. ## Behavior - The extension now remembers which messages it has shown, per community and account, in its existing notification cache (`BuzzNotificationCache`). - Each push shows the newest message not yet shown, across all communities. If every candidate was already shown, it shows the generic "You have a new message." text. - A message more than 15 minutes older than the newest one already shown, in any configured community (including one whose query failed), is treated as already covered. So a stale backlog item can't surface hours later, even from a community where nothing has been shown yet. 15 minutes matches the relay's `created_at` drift bound (`MAX_TIMESTAMP_DRIFT_SECS`), so a sender with a slow clock still gets through. A future-dated `created_at` is capped at the time it was shown, so it can't hold back later messages. - Selection and claim happen in one locked cache call. It reads each community's store once and writes only when it records a claim, so concurrent pushes can't claim against a stale view, and a rejected candidate never rewrites the store. - Retention drops only entries the age check would reject anyway. The rest are capped at the union of the newest 256 by capped time and the newest 256 by `created_at`. So neither a burst of messages nor future-dated entries can evict a message the relay still returns. The field is optional, so existing caches still decode with no version bump. - Only the newest 10 matches per community are fetched, as before. If more than 10 messages arrive before their pushes resolve, the extra pushes show the generic text. - The claim happens before presentation. If presentation then fails, that push shows the generic text and the message isn't offered again, which is better than repeating. - If the cache can't be read, dedupe is skipped (fail open), so new messages are never hidden. If a claim can't be written, the new message is still shown. An already-shown message is still rejected, since rejecting needs no write. A revoked scope is skipped. - Dedupe state lives in the extension's `Caches` directory, which iOS can purge. After a purge, the next push can show the newest message again, once. This is the NSE-only fix. It doesn't change the gateway payload or NIP-PL. ## Validation - New test `testEachPushShowsANewMessageAndNeverRepeatsOne` uses a fresh cache instance per push, to model separate extension processes. It covers: a repeat push giving the generic text; out-of-order resolution (late, then early, then nothing); a stale message outside the window; and the future-date clamp. I checked by mutation that removing any one of the three guards (id check, window, clamp) fails it. - New test `testShownMessagesStayShownAcrossCommunitiesFailuresAndBursts` covers the review findings. It checks that: - an old message isn't shown from a community with nothing shown yet, including when the other community's query fails; - a burst of 100 newer messages doesn't evict a shown mention the relay still returns; - a read-only store neither repeats a shown message nor hides a new one; - a future-dated message isn't shown again after later messages. - New test `testFutureDatedEntriesDoNotEvictAClaimedMessage`: 257 future-dated claims don't evict a just-claimed message. - Mutation checks all fail these tests: a candidate-only watermark, retention by `created_at` only, a 64-entry cap, and pruning by capped time. - Full BuzzPushKit suite on `15913d0`: 106 XCTest and 65 Swift Testing tests passed. - Live relay run (on `baac384`): a scratch test drove the real resolver and cache against a local relay. One key posted messages and another resolved five pushes (not committed): | Push | `main` | This branch | | --- | --- | --- | | 1 (after "Hello 1") | Hello 1 | Hello 1 | | 2 (no new message) | Hello 1 | You have a new message. | | 3 (after "Hello 2", "Hello 3") | Hello 3 | Hello 3 | | 4 (no new message) | Hello 3 | Hello 2 | | 5 (no new message) | Hello 3 | You have a new message. | - Automated app check: built and launched the branch on an iOS 27 simulator. The app started and showed the signed-in home screen. Only the extension uses the changed types. - An independent fresh-context review found no blockers. Its comment suggestions were applied. ### Limitations I couldn't run a real APNs push end to end. Dev-signed builds get no gateway pushes, and `simctl push` on iOS 27 doesn't invoke the Notification Service Extension. The live relay run covers the resolver and cache logic the extension runs. 🤖 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> |

perf(mobile): evict verified-profile interest in one pass (#9007)
## Summary Follow-up to [#8931](https://github.com/block/buzz/pull/8931), from Wes's [review note](https://github.com/block/buzz/pull/8931#discussion_r4456891410). [#8931](https://github.com/block/buzz/pull/8931) replaced the per-eviction scan in `VerifiedProfilesNotifier.track` with `keys.first`. That was much cheaper than main, but not constant time: removing from a Dart map leaves deleted slots, and each new `keys` iterator walks past them. One `track` call that overflows the 1,024-subject cap by E subjects still costs about E²/2 slot checks. Wes measured ~3 ms at 4,300 subjects, 62 ms at 8,600 and 205 ms at 17,200. Eviction now takes the overflow from a single iteration (`keys.take(overflow).toList()`), so it's linear. Which subjects are kept doesn't change: still the 1,024 most recently inserted. The [#8931](https://github.com/block/buzz/pull/8931) eviction test counted keys yielded by the map, which `keys.first` keeps at one per eviction, so it couldn't fail on the quadratic path. It now counts iterations started over the interest map and expects exactly one per `track` call. Main's scan and the merged `keys.first` loop both start one per eviction. ### Testing - Falsification: with the merged `keys.first` loop restored, the new test fails (`Expected: <1>, Actual: <3276>`). With this change it passes. - `flutter test test/shared/verified_profiles/`: 31 passed. The existing "keeps the 1,024 most recently tracked subjects" journey still passes, so retention is unchanged. - `just mobile-check`: clean. - `just mobile-test`: 4,227 Flutter tests passed, 40 skipped, plus 4 push and 27 crypto tests. - Automated app run: installed this build on an iOS 27 simulator (iPhone 17 Pro) signed in to a Builderlab community, opened the inbox, a channel timeline with images and the image viewer, and the channel details member list, which all track verified-profile subjects. No errors. That community is small (30 members), so the overflow path itself is covered by the unit tests, not the app run. - Agent review: an independent agent review found no blockers. - Human test: waived under the mobile testing exception; the automated app run above replaces it. Not covered: Android, and no new device profile (Wes's AOT numbers above are the cost model; this removes the E² term). 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> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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> |

perf(search): rank only the newest prefix matches and plan with the real tsquery (#8976)
## Summary Message search is one of the slowest relay queries. Short typeahead prefixes make it worst: `a:*` matches most of a community. **Why it was slow:** the tsquery was built inside a `CROSS JOIN LATERAL` subquery, so the planner saw an InitPlan and couldn't read the `search_tsv` statistics. It fell back to the default 0.5% selectivity for `@@`: for `a:*` on 1M rows it estimated 4,497 rows when 517,065 matched. Every search therefore took every GIN match, ran `ts_rank_cd` on each one, and top-N sorted them before `LIMIT 20`. This PR: 1. **Binds the real tsquery.** `push_tsquery` is unchanged. A separate `SELECT (…)::text` round trip resolves the tsquery, and the search binds it as `$q::tsquery`. An empty tsquery returns no hits without running the search. 2. **Plans each search for its own tsquery.** The search runs with `.persistent(false)`. A cached prepared statement can switch to a generic plan after five runs, and a generic plan can't see the tsquery. Forcing a generic plan lost the gain in testing. 3. **Ranks only the newest 1,000 prefix matches.** Prefix-mode relevance search ranks the newest `PREFIX_RANK_WINDOW` (1,000) matches. The inner `ORDER BY created_at DESC, id DESC LIMIT 1000` matches each partition's primary key read backwards, so for common prefixes Postgres streams the newest rows and stops at 1,000. For rarer terms it keeps the GIN bitmap plan, now with an accurate estimate. Full-text search and profile (kind:0) typeahead still rank every match. ### Behavior change: every human message search (product decision needed) Prefix mode isn't limited to keystroke typeahead. buzz-app (`useSearchMessages.ts`) and legacy desktop (`desktop/src-tauri/src/commands/messages.rs:184`) send `search_mode: "prefix"` for **all** message search. Full-text search runs only on the WS REQ path, which agents and the CLI use. So for people: - Results are the best-ranked of the newest 1,000 matches in the search's scope, not of all matches. If more than 1,000 newer messages also match, an older, more relevant message drops out of ⌘K results. The scope includes `#channel`, `from:` and date bounds, so a narrower search has the same limit within it. People have no full-text fallback. - The bridge honors `page`, and buzz-app loads later pages at 20 per page. Every page ranks the same window, so paging stays consistent, but results end after 1,000 matches (page 50). Full-text search (agents/CLI) and profile (kind:0) typeahead still rank every match. ### Perf risk: matches the backward scan has to walk far to find The planner picks the backward scan when it expects 1,000 matches near the top of the community, and it estimates that by treating each filter as independent. Two known shapes break that assumption. **Terms common in old messages but absent from recent ones.** The planner assumes matches are spread evenly over time. For a term that was common long ago but doesn't appear recently (an old project name, a former teammate), it can pick the backward primary-key scan and walk every newer row before reaching the first match. Reviewers measured this on 1.2M synthetic rows: about 2.05–2.1 s, against 0.7–1.8 s for the old query shape and 1.2 s with the GIN plan forced. The 20 s statement timeout and the #8954 cancel still bound it. The worst case is close to the old `a:*` worst case, but it now scales with community size, not match count. The planned EXPLAIN on production-shaped data will include such a term. **Terms common in channels the searcher can't read.** Human search always adds `channel_id = ANY(<readable channels>) OR channel_id IS NULL` (`build_search_channel_scope_filter`). A term that is common in private channels or other people's DMs can get a high match estimate, take the backward scan, and walk the community's rows to find a few readable matches, where the old shape used the GIN bitmap. This hasn't been reproduced yet; the production-shaped EXPLAIN will include such a term next to the old-only one. The same timeout and cancel bound it. ### Cost - One extra round trip per search to resolve the tsquery (about 0.03 ms of execution). It runs on the same pool checkout as the search (`cancel::fetch_all` takes the caller's connection), so a busy pool queues each search once. An IMMUTABLE SQL function could remove the round trip, but that needs a migration, so it's not done here. ### Related issue - Follows #8954 (cancel abandoned searches, bound the search pool) and #8964 (closed in favor of #8954). - Builds on #8947 (3-character server-side prefix minimum), merged from main. The resolve step passes its minimum. When the trailing prefix is too short, the resolved tsquery is NULL, and the search returns no hits without running the second query. - Client-side pairing: block/buzz-app#2210 (3-character last-word minimum for ⌘K message search). ## Testing **EXPLAIN ANALYZE on a synthetic 1M-row `events` table** (monthly partitions, GIN on `search_tsv`, kinds 9/40002/40008, custom plans, warm cache): | Prefix | Matches | Before | After | Plan after | |---|---|---|---|---| | `a` | 517k | 322 ms | **0.7 ms** | backward primary-key scan per partition, stops at 1,000 | | `th` | 137k | 127 ms | **1.2 ms** | backward primary-key scan, stops at 1,000 | | `a` (community with 10% of rows) | — | ~100 ms | **1–2 ms** | backward primary-key scan | | `deploy` | 8.2k | 15 ms | 5–10 ms | GIN bitmap, accurate estimate | | `d278` | 500 | 1.1 ms | 0.5 ms | GIN bitmap | | rare word | 0 | 0.07 ms | 0.03 ms | GIN bitmap | **Postgres integration tests:** - New test `prefix_relevance_ranks_only_the_newest_matches`. An old, highly relevant message drops out of prefix results behind 1,000 newer matches but still ranks first in full-text search. Prefix pages end at page 50. An old, best-ranked profile still tops profile typeahead behind 1,000 newer profile matches. Removing the window fails the test, and so does applying it to profiles. - `abandoned_search_cancels_its_statement`: the `pg_stat_activity` matcher now looks for `ts_rank_cd(`, because the old `search_query.query` text no longer exists. - Locally, each test ran against a fresh database because `cargo-nextest` isn't installed, so the hosted lane hasn't run yet. 26 of 27 pass. `artifact_search_uses_only_live_current_head` also fails on unmodified main in that local setup, so the failure isn't from this change. **Checks:** `cargo fmt --check` and `cargo clippy -p buzz-search --all-targets -D warnings` are clean. **Not yet done:** - hosted CI; - a manual check against a local relay with ⌘K typeahead; - EXPLAIN against production-shaped data, including a term common only in old messages and a term common only in channels the searcher can't read. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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. A rendered widget preview verifies the container and elbow; live acceptance remains pending. Self-review found no blockers in the changed paths. Review status is preserved. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz> |

Modernize mobile channel and DM creation sheets (#8942)
Modernizes New Channel and New DM with full-height forms and X/Create or X/checkmark actions. iOS uses UIKit sheets throughout; Android uses the Flutter fallback. Channel menus default to Ongoing/Public, and native menu previews lift only the trailing value while labels stay fixed. Channel names disable automatic capitalization, autocorrect, and spellcheck; both platforms use descriptive placeholders. Preserves recipient search and limits, creation error retries, and navigation after native dismissal. Validation: 4,154 mobile tests passed (38 skipped), auxiliary suites and static checks passed; iOS device/simulator and Android builds passed. Exercised menus, dismissal, DM search and selection in the simulator and Android form behavior on Pixel; iPhone UI tested and approved by the author. | iOS native form (Simulator) | Android Flutter form (Pixel) | | --- | --- | |  |  | Native menu with the left label fixed:  --------- Signed-off-by: kenny lopez <klopez4212@gmail.com> Co-authored-by: Terp <5856f6900e8e0a4e0ea1f4f8d2ee33e4753d2119bc122f94ecafc660b46c0511@buzz.block.builderlab.xyz> |

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> |

perf(mobile): evict verified-profile interest in constant time (#8931)
## Summary `VerifiedProfilesNotifier.track` trims its interest map to 1,024 subjects, but it finds the oldest subject by scanning every entry, once per eviction. Opening #announcements (4,302 members) evicts about 3,300 subjects, which is roughly 3.4 million comparisons. On a 12 mini Profile build that was 316 ms of main thread, inside the channel's 134 to 167 ms opening frames. It runs whether or not the relay serves verified profiles, so it also affects the prod Block community. A subject's interest is set once, on insertion (`??=`), so the map's insertion order is interest order. The oldest subject is therefore `keys.first`, and eviction is constant time. Which subjects are kept does not change. ### Related issue None found. ### Testing - New `verified_profile_directory_test.dart` case: tracking 4,300 subjects keeps exactly the 1,024 most recently tracked ones, and tracking a subject again does not refresh its age. This test checks that behavior is preserved, and it passes on main too. The speedup comes from removing the per-eviction scan, which the device CPU profile attributed. - `just mobile-check` passes. `flutter test test/shared/verified_profiles/` passes (30 tests). The pre-push hook ran the mobile unit tests. - Device (12 mini, Profile build, opening #announcements, first 5 s; runs not matched): `VerifiedProfilesNotifier.track` inclusive CPU 316 ms before, 14 ms after. Opening frames of 134 to 141 ms remain, mostly the channel name scope (follow-up). Not covered: a human test (waived under the mobile testing exception), Android. Separately, the 1,024 cap still churns subscriptions for rosters larger than that.

perf(relay): cut writer-pool round trips past the 48k relay ceiling (#8846)
## Summary Five changes that take load off the writer pool and the relay's connection bookkeeping. On a single-relay load rig, the clean ceiling moves from 40k to about 48k WebSocket clients. In the A/B, connect p99 at 48k fell from 4.1 s (abort) to 1.65 s. 1. **Ban/mute restriction cache with a 1 s max age.** HTTP API requests, publishes and ephemeral writes read `(community, pubkey)` restriction state through one cache. An entry is served for 1 s from when its read began, matching the open-channel cache's bound. Socket admission, moderation-command actor checks and the `/buzz/v1` ban recheck still read fresh. An admitted socket outlives the 1 s window, so a banned client that reconnects inside it would otherwise keep a socket open indefinitely. A ban drops the target's entry, and each owned agent's entry, on every pod as part of the live-disconnect fan-out, best-effort. Timeouts, untimeouts and unbans drop it on the pod that handles them. 2. **Fewer round trips per event read.** Replica reads skip the per-read `statement_timeout` tighten, because the reader pool installs the deadline at connect. They keep the savepoint, so a failed or cancelled read leaves the session usable and releases its locks. That takes them from 4 round trips to 3. Writer reads send `BEGIN` and the tighten as one message, which also takes them from 4 to 3. 3. **Concurrent open-channel cache misses share one read.** The first miss in a community takes a per-community gate and reads; the others wait for it and use its result. A waiter whose leader failed reads once on its own and does not queue again. A waiter also stops waiting after the cache's 1 s max age and reads on its own, because the leader's set would be stale by then anyway. So a leader whose read hangs stalls only its own request. 4. **`has_admitted_connection` is one map lookup.** A `(community, pubkey) → admitted count` index is maintained under each socket's pubkey lock in `mark_admitted`, `set_authenticated_identity` and `deregister`. It replaces a scan of every connection on each disconnect. 5. **Host → community cache with a 1 s max age.** Only successful lookups are cached; unmapped hosts and errors go to the database every time. ## What got simpler - The ban handler's separate pod-local cache drop is gone; the disconnect every ban already runs covers it on every pod. - One write-restriction gate instead of two. `enforce_cached_write_restriction`, `enforce_relay_membership_ephemeral` and the `cached_ban` parameter chain through `enforce_membership` / `admit_member` / `deny_banned` are deleted. - The ephemeral path's separate 30 s ban cache is gone, so the relay has one staleness rule for restriction state instead of two. ## Notes - Bans reach the restriction cache on every pod. Every ban path (signed command, report action, relay admin) closes the target's and its agents' sockets clusterwide, and each pod drops those entries in the same step. A dropped Redis publish, or a restriction read already in flight when the drop lands (it can refill the old row), falls back to the 1 s bound. Timeouts on other pods also rely on the 1 s bound, and so do unbans and untimeouts, which fail closed. - On the load rig the restriction-cache hit rate was 28%, because HTTP agents poll every 5 s. A longer TTL with Redis invalidation would raise it, but that is a separate change. ## Load test Single relay pinned to 8 cores, native Postgres 16, a seeded fixture with 2,000 open channels, and a 6-shard generator. Steady ramp with 120 s holds; a step aborts at p99 > 3 s. Each step adds 10% HTTP agents. | clients | base connect p99 | this PR connect p99 | base relay cores | this PR relay cores | |---|---|---|---|---| | 32k | 34 ms | 31 ms | 1.71 | 1.66 | | 40k | 45 ms | 26 ms | 2.33 | 2.15 | | 48k | 4,107 ms (abort) | 1,652 ms | 4.7 | 3.0 | | 56k | n/a | 4,535 ms (abort) | n/a | 4.0 | Open-channel re-reads over the run fell from 72k to 1.6k. The tenant cache hit rate was 94%. 48k is this branch's knee. A later run of the same build aborted at 48k: connect p99 2.2 s, but 29% subscribe errors from the concurrent-handler cap. With a 10 s restriction max age, it passed 48k, at connect p99 1.56 s, 60% hit rate and 10% fewer relay cores, and both arms stopped at 56k. ## Testing - `cargo fmt --check`, `cargo clippy -p buzz-relay -p buzz-db --all-targets -D warnings` - `cargo test -p buzz-db --lib` and `-p buzz-relay --lib`, run in parallel. The only failures were 8 DB-seeding tests that need a migrated default database; the Postgres lane covers them. Commits after that run changed the replica savepoint, the `/buzz/v1` recheck revert and some test edits. - Postgres lane at head: `scripts/postgres-test-run.sh -p buzz-relay -p buzz-db --lib --bins --tests`. All 1,183 tests passed. - Mutants. Each one must turn its new test red: - waiters skipping the gate - a no-op index removal - the tenant cache ignoring age - the restriction cache ignoring age - a waiter waiting on the gate with no limit - a disconnect that keeps the cached restriction row - replica reads dropping the savepoint buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(search): skip message prefix search below three characters (#8947)
## Summary
Typeahead surfaces (the buzz-app and desktop topbars) send a NIP-50
search with `search_mode: "prefix"` whenever typing pauses. A one- or
two-character trailing `:*` prefix matches a large share of every
indexed message. The GIN index on `search_tsv` can't stop early or
return rows in rank order, so Postgres fetches, rechecks and ranks every
match before it applies `LIMIT`. In a large community, each of these
queries costs seconds of database CPU.
With this change, prefix-mode `search()` returns no hits when the
trailing whitespace token yields a lexeme shorter than three characters
(`PREFIX_MIN_CHARS`). The check runs inside the prefix tsquery SQL, on
the output of the same `to_tsvector('simple', …)` call that decides
which lexemes get `:*`. Punctuation therefore can't pad the count:
`pr.`, `@pr`, `#pr`, `c++`, `don't` and `pre-p` are all held back, and
`project ?` still runs, because `?` yields no `:*` lexeme. When the rule
applies, the tsquery is NULL, so it matches nothing and the GIN index
lookup returns no rows. Completed words in front of the trailing token
don't matter: `"the p"` runs the same broad `p:*` lookup as `"p"`.
Kind:0-only queries (profile typeahead) are exempt because there are few
profiles, and the short-name exact-lexeme ordering relies on one- and
two-character queries. `search_profile_names` is unchanged. Full-text
mode is unchanged.
Only the HTTP bridge (`POST /query` with `search_mode: "prefix"`)
reaches prefix mode. WebSocket REQ search always uses full-text mode, so
this change doesn't affect it.
## What got simpler
The kind:0-only predicate is now computed once (`profile_only`) and
shared by the new minimum and the existing exact-lexeme ordering. The
minimum lives in the one SQL fragment that already tokenizes the query,
so there is no second tokenizer in Rust to keep in sync with Postgres.
No new concepts beyond one constant.
## Known limits
- This bounds the worst case only. A common three-character prefix can
still match enough rows to be expensive. Bounding that needs a product
decision, such as a recency window for typeahead or a different index.
- Two-character CJK words (for example `東京`) get no message typeahead
until a third character. A trailing contraction or hyphenated word with
a short part (`don't`, `e-m`) gets none until the next word is started.
Full-text mode is unaffected.
- Clients should not show "no results" for one- and two-character input.
A client-side minimum is a companion change. That includes the legacy
desktop topbar in this repo (`desktop/src/features/search/hooks.ts`,
which searches at 2 characters globally and 1 in a channel); it is left
out here to keep this PR relay-only.
## Testing
- Extended
`prefix_mode_matches_final_token_prefix_without_changing_full_text` with
a table of prefix queries and the exact hit sets they must return. It
pins no hits for a trailing token that yields a lexeme below three
characters: alone, after a completed word (`project pr`), padded with
punctuation (`pr.`, `@pr`, `#pr`, `...p`), as a contraction (`don't`),
and hyphenated (`pre-p`). It covers `kinds = [9]`, no kinds, mixed `[0,
9]`, and `Newest` sort. Each of those rows has data it would match
without the minimum. The same table has controls that must still match:
`pro.`, `project ?` (punctuation-only trailing token), `pre-pro`, `t
pan` (a short completed word stays exact and isn't limited), and a
one-character kind:0 `p`. A full-text `don't` control shows that
full-text mode is unaffected.
`short_kind0_prefix_prioritizes_exact_lexeme_on_a_noisy_page` pins the
kind:0 exemption.
- Mutation-checked on Blox. Each of these fails a test: removing the
minimum, removing the kind:0 exemption, and applying the minimum to
every lexeme instead of only the trailing ones.
- Synthetic plan check on Blox Postgres (300k rows, GIN on a generated
`simple` tsvector, same `CROSS JOIN LATERAL` query shape). `'pr':*` took
3.6 s and read 10,411 buffers. The NULL tsquery took 0.01 ms: the bitmap
scan returned 0 rows and read no buffers.
- Two existing prefix tests used a two-character trailing token
(`project pl`, `alpha be`). They now use three or more characters
(`project plan`, `alpha bet`) and assert the same behavior.
- Blox: `cargo fmt --check`, `cargo clippy -p buzz-search --all-targets
-D warnings`, `buzz-search` unit tests, and the `buzz-search` Postgres
lane (`scripts/postgres-test-run.sh`).

perf(mobile): cheaper identity-name rebuilds for large rosters (#8936)
## Summary Every identity-name source change (a profile batch, a verified name) rebuilds a channel's naming scope over its whole member list. In a 4,000-member channel, each rebuild derived every key's naming fact more than once: owner loading and resolution each derived it, and so did each label for a key outside the scope. It also checked every key against a regular expression several times, and iOS AOT builds run regular expressions in an interpreter. - `IdentityNames` derives each key's naming fact once per scope. - `isHexPubkey`: a character-loop hex check, used by the identity-name code instead of the regular expressions. Labels are unchanged. ## Measurements These were taken with an earlier version of this PR that also cached npub encoding. That cache was removed to keep the change small, so the remaining gain is smaller than shown. I haven't re-measured it. - **Synthetic** (Mac, `flutter test`, 4,391 members, 60% with profiles; scope, `missingOwnerProfiles` and every label for each new sources object): a warm rebuild took 63 ms before and 12 ms with the cache. The first rebuild took 120 ms before and 91 ms with the cache. - **Device** (iPhone 12 mini, Profile build, first 5 s after opening #announcements with 4,391 members; runs not matched): `channelIdentityNamesProvider` plus `watchChannelIdentityLabel` inclusive CPU was 148 ms before and 81 ms with the cache. Of that, `fullNpub` (npub encoding, the cached part) went from 62 ms to 22 ms. The identity path no longer calls `RegExp.hasMatch`. ## Testing - A new test counts profile lookups. Owner loading, every label and an outside key read each member's profile once. Without the memo, each is read 3 times. - New `isHexPubkey` tests cover both cases, wrong lengths, characters just outside each range, and a bad character at every position. - `just mobile-check mobile-test` passes. 🤖 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> |

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. Thus a rebuild of `MaterialApp` still makes new app theme data one time. This costs only a little performance. We did not change it. Not tested: A human test did not occur. The mobile testing exception waives it, and an agent did the device test. No test occurred on an Android device. 🤖 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> |

perf(mobile): verify owned-agent registrations natively (#8938)
## Summary `loadOwnedAgentDirectory` checks the signature of each kind:30177 agent registration before it trusts the registration's `model`. It did this with `nostr.Event.fromJson`, which runs the `nostr` package's pure-Dart Schnorr code on the UI isolate. This change uses `verifiedNostrEventFromJson`, which the app's other verification sites already use. It makes the same timestamp, event id and BIP-340 signature checks with the bundled libsecp256k1. It also requires lowercase hex for the pubkey and signature, which relay events already use. A registration that fails verification still lists its agent without a model, as before. ## Measurements - **Synthetic** (Mac, `flutter test`, 20 signed registrations, warm): pure Dart 163 ms, native 2.6 ms. - **Device** (iPhone 12 mini, Profile build, first channel open after launch, first 5 s; runs not matched): `loadOwnedAgentDirectory` inclusive CPU was 71 ms before (69 ms in `Event._assertValid`) and 2 ms after. ## Testing - New test: a registration with a wrong signature still lists the agent, with no model. The correctly signed registration keeps its model. - `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> |

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> |

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> |

docs(mobile): recommend Xcode 27.1 (#8949)
Updates the recommended Xcode from 27.0 to 27.1 in `mobile/README.md` (iOS toolchain section and the `DEVELOPER_DIR` example) and the `CONTRIBUTING.md` prerequisites table. Release pipelines move to Xcode 27.1.0 in [squareup/buzz-releases#118](https://github.com/squareup/buzz-releases/pull/118), because mobuild CI images no longer install 27.0. This repo's GitHub CI uses `macos-latest` with no Xcode pin, so no workflow changes are needed. ## Testing - With Xcode 27.1 (27A9275) selected, a clean `flutter build ipa --release --no-codesign` of `mobile/` on main succeeded (`Buzz.xcarchive`, 95s). That is the release pipeline's IPA build without signing. - Docs-only change, so no app test run. 🤖 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@localhost> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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. I did no device run. 🤖 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> |

fix(mobile): drop the # from Solo chat names in push notifications (#8955)
## Summary
Push notifications for Solo chats were titled like channels (`#Trip
planning`). The iOS notification extension added `#` to every stream and
forum conversation name, but the app presents Solo chats as personal
chats, not channels.
- `BuzzPushCachedChannel` gains optional `isSolo` and `creatorPubkey`,
derived from relay kind 39000 metadata. `isSolo` uses the same rule as
the app's `Channel.isSolo`: a private stream whose NIP-CL labels (every
`t` after the leading type) include `buzz.solo`. `creatorPubkey` is the
relay-authored `P` tag.
- The resolver uses the bare channel name only for the viewer's own Solo
chats (matching `Channel.isPersonalChat`, which requires `createdBy ==
viewer`). Someone else's Solo chat, and every other channel, keeps
`#name`.
- `isSolo` is optional, so existing App Group caches still decode.
Entries cached before this change have no flag and keep the `#` until
their metadata is refreshed.
## Validation
- `swift test --package-path mobile/ios/BuzzPushKit`: 104 XCTest and 66
Swift Testing tests pass, including two new ones:
- `testOnlyOwnSoloChatConversationNameDropsChannelHash`: a fresh Solo
metadata fetch yields `Trip planning` when the viewer created the chat
and `#Trip planning` when someone else did. Removing the creator check
makes it fail.
- `soloClassification`: only private `stream` channels labelled
`buzz.solo` are marked Solo (open, forum, label-only and unlabelled
private streams are not), and the `P` creator is cached lowercased.
- Live relay check: a local relay with synthetic identities, a Solo chat
("Weekend plans") and a private channel ("design-review"), each with a
second member who posts. The production `BuzzPushNotificationResolver`
(the code the notification extension calls), run against relay-built
kind 39000 metadata, gives:
| | Solo chat | Channel |
|---|---|---|
| main | `#Weekend plans` | `#design-review` |
| this PR | `Weekend plans` | `#design-review` |
- Not covered: a banner rendered by the notification extension. `simctl
push` delivers to the simulator as a local notification and never
launches the extension, and a real APNs push needs credentials this
machine doesn't have.
## Follow-up after merge
Merging on the live relay check above. Still to do once a dogfood build
includes this change:
- [ ] On-device push check on a BLIMP: a Solo chat push shows the bare
name and a channel push keeps `#name`.
- [ ] Before/after notification screenshots.

fix(mobile): allow community removal without a cached push grant (#8978)
## Summary Fix community removal failing with “Expected exactly one endpoint grant for push lease revocation” when saved push state exists but the current build has no cached grant, including builds without a push gateway. When the community has a saved installation ID, journal its targeted revocation without requiring the grant. An unknown grant expiry stays unknown: retain cleanup credentials until the relay accepts the revocation. Existing known-expiry cleanup and legacy grant-based addressing remain unchanged. ### Related issue No matching open issue found. Follows [the durable revocation outbox](https://github.com/block/buzz/pull/8706). ### Testing The new regression fails with the reported error on the preceding implementation. It now verifies missing-grant enqueue, offline retry, persistence across restart, the exact lease address and eventual cleanup after acceptance. On a physical iPhone with the fix applied to the onboarding test build, the previously failing community removal succeeded. Unknown-expiry records retain their signing key in secure storage until successful revocation. Downgrading to a client that requires an integer expiry will reject those pending records.
