Tom Brow	da93ce3f62	fix(mobile): open the public Builderlab login the iOS bridge allows (#8914) ... On main, "or sign in with email" on iOS fails immediately with "We could not finish connecting. You can try again." No Builderlab page opens. [#8700](https://github.com/block/buzz/pull/8700) changed the iOS browser bridge so the public account hosts (`app.builderlab.xyz`, `app.builderlabstaging.xyz`) may only open `/auth/native`. The Dart side still opens `/api/goose/v1/auth/login` for them, so the bridge rejects every public sign-in before presenting a browser. Every iOS build since #8700 is affected; organization sign-in on tenant hosts is not. The matching Dart change was Wes's [#8712](https://github.com/block/buzz/pull/8712). It was merged into the #8700 branch, but main's squash of #8700 kept only the bridge half. This PR restores #8712 on top of main: - The public account opens `/auth/native` (state, S256 challenge, callback and retained invite unchanged, without the CLI-only `type`/`product` parameters). Organization tenants keep `/api/goose/v1/auth/login`. - A saved session whose account still needs web setup goes through the same browser handoff, keeping its subject and destination. Android has no path allowlist in its browser plugin, so it needs no change. ### Validation - Reproduced on an iPhone 17 Pro (iOS 27) simulator with a main-based debug build: "or sign in with email" fails instantly. With this change applied, the same build shows the system "Buzz wants to use app.builderlab.xyz to sign in" prompt, then the login.builderlab.xyz "Welcome back to Buzz" page, which confirms production serves `/auth/native`. - Restored #8712's tests on top of main's current tests: the browser test checks the public login URL and its exact parameters, and the hosted invite journey runs for both a fresh account and a saved account that still needs setup, asserting `/auth/native` and that the invite is retained. Without the Dart fix, these fail. - Mobile format and analyze pass; the hosted onboarding journeys and `shared/hosted` tests pass with the CI auth-domain configuration. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz>	2026-11-02 10:00:08 -08:00
Tom Brow	db4478e8d2	feat(mobile): organization sign-in for NIP-FI relays (#8700) ... Block is turning on NIP-FI enforcement on the Block relay. Desktop gets organization sign-in in block/buzz-app#1424. Mobile can already attach NIP-FI assertions, but only for Builderlab-hosted communities, through the build's single Builderlab account. The dogfood build needs that account for public hosted communities, so it can't simply be pointed at the Block tenant. This adds a separate **organization realm**, configured at build time: - `BUZZ_ORGANIZATION_URL`: the tenant's HTTPS origin (for example `https://block.builderlab.xyz`). - `BUZZ_ORGANIZATION_RELAYS`: the exact relay hosts that trust that tenant. The two must be set together. The app refuses to start if they're malformed, overlap a hosted community, or reuse the hosted origin. Without them, nothing changes. For a configured relay: - The app keeps its own organization session and signs in through the browser at the tenant's existing login (`/api/goose/v1/auth/login`). Block SSO happens there. - It requests assertions from the same `/v1/buzz/identity/assertions` route that hosted communities use, and attaches them to the relay socket, HTTP, media, huddle and remote-agent requests. - Unlike the hosted path, it doesn't require an identity backup before the first binding. As on desktop, the tenant binds the member's existing key on first issuance. A key already bound to a different one is refused before any request is sent. - When signed out, it connects without an assertion and lets the relay decide. A bottom banner offers **Sign in**. After sign-in, the relay reconnects with a fresh assertion. Hosted communities keep their existing banner and flow. The tenant accepts only the registered `xyz.block.buzz.mobile:/auth/callback` return URL, so both realms share it. Each `BrowserAuth` owner leaves callbacks whose `state` belongs to another owner's attempt to that owner. ### Before merge - [ ] Kenny Lopez reviews the visible changes. ### Validation Added tests (`organization_relay_auth_test.dart`): - Configuration parsing and exact host matching. - An assertion is issued for the exact relay and key, then cached. - A different bound key is refused. - Signed out connects without an assertion. - Other relays never receive the assertion. - The shared callback is routed between the hosted and organization owners. Full `mobile-check` and `mobile-test` pass. RunnerTests pass locally except `testNativeNavigationTitleExpandsAgainAtTop`, which this PR doesn't touch. Added tests (`organization_sign_in_test.dart`, `relay_auth_isolation_test.dart`, `builderlab_account_test.dart`), each failing without its fix: - Concurrent account restores at cold start share one adopted account. - An exchange from a cancelled attempt never changes a newer sign-in. - Storage failures while clearing the intent or cancelling leave the busy state. - An unreadable saved organization session is replaced by signing in again. - A stalled organization issuer never delays a hosted relay's assertion. This test needs `BUZZ_AUTH_DOMAINS` and skips without it. CI's configured-auth-domains step doesn't list it yet, because that workflow change needs a token with `workflow` scope. Added tests also cover a restore after an offline start (the banner clears once a relay retry restores the session) and the iOS bridge allowlist (`/auth/native` and tenant login on Builderlab subdomains; other hosts, paths, ports, userinfo and fragments refused). Simulator (iPhone 17, iOS 27) with the dogfood defines against the production Block relay `buzz.block.builderlab.xyz`, on a WARP Mac: - The app starts with the organization configuration and connects to the relay while signed out, showing the organization **Sign in** banner. - **Sign in** opens the system sign-in session for `block.builderlab.xyz`, and the banner shows **Finishing organization sign-in…**. Cancelling returns to **Sign in** with no error. Before the bridge fix, no browser opened and the banner reported that sign-in did not finish. - The bottom banners (organization sign-in, hosted reconnect, and the sign-in recovery row) now sit above Home's floating Search/New bar, which used to cover **Sign in**. A journey test checks the banner clears the bar, and fails without the fix.  - The simulator run stopped at the system consent prompt (SSO does not work in the simulator). The app calls were driven through the VM service (the same `signIn()`/`cancel()` the banner buttons call) because the simulator could not be tapped. Device (iPhone 12 mini) against bb-block staging in enforce mode, where every probe without an assertion gets 401: - Signed out, the organization banner shows and the app stays responsive. Cancel at the consent prompt returns to **Sign in**, and retry works. - Block SSO through Okta completes, and the relay admits the reconnect with the assertion. - After relaunch the app connects, loads channel history, and shows no banner for over 60 seconds. - Before the restore fix, 2 of 4 cold starts showed "cannot use this community with this key" although the session was valid. With it, 8 of 8 cold starts connected. Known limitation: adding an enforcing organization relay by community link is tracked in #8791. The dogfood build enables this in squareup/buzz-releases (`tomb/dogfood-organization-sign-in`). App Store builds stay unchanged. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@squareup.com> Co-authored-by: Tom Brow <tomb@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-11-01 07:23:12 -08:00
Wes	f59b326568	Fix mobile onboarding policy loading, browser cancellation and pairing feedback (#8874) ... Mobile onboarding could reject valid large legal documents, stay busy after closing Android browser sign-in, and hide pairing-import errors behind the community-link form. This change bounds join-policy responses at 4 MiB while retaining 64 KiB for other responses, handles Android browser cancellation through the native lifecycle/channel, keeps Cancel sign-in usable, and shows friendly pairing errors on the landing screen with a live-region announcement. Identity mismatch checks remain intact. The browser-cancellation implementation incorporates the candidate from #8847 (`cb241b3f1`); coordinate landing to avoid duplicate work. This PR consolidates the three fixes exercised together during Android onboarding acceptance. ## Validation - Pixel 9 / Android 17, production hosted services, isolated debug installs. Human acceptance plus native UI, saved public-identity and restart checks as noted below. No iOS acceptance in this session. - Latest build and invite-first acceptance: base `a12ad1cdd29da8b2923eca5408e963a2659777ab` plus these patches. - Focused tests on that base plus patches: **88 passed** across hosted_journeys_test, hosted_admission_test, browser_auth_test, pairing_hosted_handoff_test and pairing_provider_test, with `BUZZ_AUTH_DOMAINS=communities.buzz.xyz`. - Earlier baseline: 81 focused cases passed plus one staging-configuration case passed separately (82 distinct cases across seven onboarding/recovery files); these are historical, not current-head certification. - Earlier policy change: 41 focused tests, changed-file analysis and isolated mutation check passed on the earlier base. Earlier browser candidate native instrumentation/mutation evidence was not rerun on this combined revision. - Android debug APK built and installed successfully. Mandatory commit/push hooks passed at `6442e5ff9`: analysis clean; mobile tests 4,047 passed / 34 skipped; additional package runs 4 and 27 passed; file-size checks passed. These broad tests ran through the required push hook, not a manually invoked suite. CI remains pending. ## Live testing report — October 31 | Journey | Result and evidence boundary | |---|---| | Fresh email signup / identity / hosted invite | Reproduced policy response exceeding 64 KiB; after fix, admission and restart passed. Profile/message visible locally; cross-account message receipt remains unproven. Tested at `cfcaef4e9f` plus policy patch. | | Browser close → retry → login → existing identity recovery → restart | Passed at `d14f33a170` plus patches; recovered the expected public identity and community. | | Pairing a different identity into an existing install | Rejected without replacing the original key. Initially hidden error became visible with friendly copy; Back and restart preserved the community at `b80217de3` plus patches. | | Fresh pairing → wait for desktop approval → sign-in → community → restart | Passed at `20742a236` plus patches; human confirmed approval gate, saved public identity matched. | | First-time desktop cancellation → welcome → fresh QR retry → community → restart | Passed at `20742a236` plus patches. Cancellation error remained raw `user_denied`. | | Android system Back while awaiting pairing approval | Human-confirmed in already-onboarded Add Community; first-time phone-side Back variation remains untested. | | Wrong pairing code → rejection → correction → completion | Human-confirmed at `a2540fbe3` plus patches. Exact error and same-session versus fresh-QR retry were not independently captured. | | Interrupt account onboarding at community picker → process restart → recovery → admission | Passed at `a2540fbe3` plus patches. Restart opened Add a community; Find my communities restored choices without another login. Human completed admission. No destination had yet been selected. | | Invite-first into fresh signed-out app → intended community → restart | Passed at `a12ad1cdd` plus patches; saved identity/destination matched. Existing member and existing browser session. Initial Android VIEW intent explicitly targeted the test package; ordinary HTTPS default app-link resolution and new-member admission remain untested. | | Malformed community input → error → Back → restart | Passed for `not a community`; original community preserved. `not-a-community` is a valid single-label hostname and was not counted as malformed-input evidence. | ## Remaining gaps and findings Not release certification. Pairing landing-error regression/mutation evidence is now recorded below. Current combined-revision native instrumentation has not been rerun; its limited scope is described below. Deferred behavior, not implemented here: - Wrong browser account after fresh pairing is correctly rejected, but Retry reuses that app account session; in-app account switching must preserve the transferred identity and destination. The live happy path used a manual browser-account switch and fresh install. - Pairing wait has no visible Cancel; tested system Back works. - Desktop cancellation exposes raw error wording. - Interrupted community selection requires an extra Find my communities step. Master checklist remains partial: seven categories exercised this session, signup/community creation has historical coverage, seven categories unexercised. New-member link-first admission, deeper interruption/server-commit recovery, expiry/revocation/network failures, key import, organization/self-hosted paths, phone-to-desktop transfer, eligibility gates, accessibility/app-link variants and iOS require separate coverage. Channel-discovery work is separate (#8869). ## Review checkpoint [Carl’s review](https://github.com/block/buzz/pull/8874#pullrequestreview-5724095754) found no code blockers at `6442e5ff9`. Carl also reviewed test-only follow-up `d43958653` and found no issues, accepting both validation gaps as closed. A subsequent review identified stale callback → resume cancelling a newer Android login. A narrow native fix and regression validation are in progress; prior readiness attestation is withdrawn pending this behavior change. - **Android stack check passed (Pixel 9, Android 17):** after fresh account sign-in, the human stopped at the community picker without closing/restarting. `dumpsys activity activities` showed exactly one MainActivity in Invite First task 567, with no CustomTab in that task or the full component list. ChromeTabbedActivity remained in a separate pre-existing browser task. This rules out a lingering duplicate activity in this run; it does not independently trace `onNewIntent` or establish all Android/browser variants. Binary production sources match `6442e5ff9`. - **Pairing regression/mutation passed:** extended the existing QR journey using the real encrypted NIP-AB import and hosted coordinator. Asserts visible friendly mismatch feedback, live-region wrapper, unchanged stored community/account identity, and Back to home. Reused the existing socket fake. Hosted journey + pairing provider files: 70 passed with configured auth domain; opt-out hosted journey file: 3 passed / 21 skipped; changed-file analysis clean. Isolated clone: control passed, hiding the landing error failed the visible text assertion, restoration passed. No production source change in this follow-up. - **Duplicate landing:** #8847 is superseded by this combined PR; its Android slice is included here. No merge performed. BrowserAuthPluginTest manually drives plugin hooks using an unmanaged Activity and fake browser launcher. It proves the plugin state machine only, not MainActivity wiring, real lifecycle order, process death, or duplicate app_links callback delivery. Current CI does not run Android instrumentation. Android ignores the debug ephemeral-login flag and shares browser cookies. Readiness checklist: agent review completed on production changes and test follow-up; agent exercised the changed behavior; human completed the documented Android journeys and final sign-in check. ## Stale callback follow-up (`b7aaaa788`) Addresses [the later Android lifecycle review](https://github.com/block/buzz/pull/8874#pullrequestreview-5724197312): a recognized callback now clears browser-dismissal tracking before rejecting a mismatched state. A stale callback cannot complete or cancel the newer login. The existing native journey now includes the intervening resume, successful current callback, and genuine browser dismissal after a stale callback. Only two native files changed; policy and pairing fixes are unchanged. Validation: 88 focused Dart tests passed. Android app and test APK build passed. On Pixel 9, the native plugin journey passed; in an isolated source/Git/build clone, removing the reset failed at the newer attempt's expected-zero-replies assertion; exact restoration passed. This proves the plugin state machine on Android, not a real late browser callback through OS lifecycle delivery. Carl reviewed `b7aaaa788` and found the fix correct and minimal with no blockers. Human browser-close/retry check remains pending; PR stays draft until that passes. Current-head CI is also required for merge. Accepted limitation: if a recognized stale callback arrives after the current browser tab has already gone, automatic dismissal is suppressed and the user may need the visible Cancel button. The callback cannot complete sign-in without matching state; Dart validation remains authoritative. --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz>	2026-10-31 12:43:01 -06:00
Wes	b6aa5539e3	feat(mobile): account onboarding, key recovery and hosted reconnect (#8375) ... ## Behavior Adds optional mobile Builderlab sign-in, identity backup/recovery, community discovery/creation, and account-aware reconnect. **Builderlab features are disabled by default:** when `BUZZ_AUTH_DOMAINS` is unset or empty, account login, creation, backup/recovery, reconnect prompts, and background account restoration are hidden/disabled. QR/code pairing, links, and invites retain Nostr-only entry. Saved account state is retained for later opt-in. `--dart-define=BUZZ_AUTH_DOMAINS=communities.buzz.xyz,communities.public.builderlabstaging.xyz` opts those DNS domains and their subdomains into required account setup. The same policy gates pairing, deep links, durable community admission, and reconnect. A nonempty list enables Builderlab features; `BUZZ_BUILDERLAB_URL` alone does not. Enabled flows still require their backend services. Existing Nostr relay authentication remains mandatory. `BUZZ_HOSTED_RELAY_AUTH=true` enables scoped relay assertions and reconnect prompts only for configured authentication domains. Configure assertion issuance and each community's issuer binding before enabling assertions; enable relay enforcement last. Account credentials stay at Builderlab. Wrong-account recovery preserves keys; failed writes are not replayed; authentication is bounded by request deadlines. Hosted flows preserve keys across cancellation/restart, reconcile interrupted creation/invitation acceptance, and support manual nsec file import/export. Account identities are scoped to backend and authenticated subject; reusing an existing local key for an unbound account requires an explicit selection. Recovery reconciles the advertised and recovered inventories before automatic selection. Successful self-hosted admission retires its pending key, and iOS startup removes interrupted export files. Adds authenticated relay `GET /operator/communities/joined` for the companion Builderlab membership endpoint. ## Validation - Follow-up review repair at `66a12ac92`: self-hosted entry presents readable choices and import despite incomplete enumeration, while generation still requires a complete empty inventory; explicit selection uses exact-key lookup. Consuming a value-equal duplicate now advances dispatch. Reconnect requires an existing account binding or a subject-scoped backup receipt before signing an assertion, and pins the subject inside the serialized account request. An empty different account is refused without sending key proof. Focused checks: configured domains 58 passed; default 49 passed, 9 hosted-only skips. Separate isolated mutations fail the incomplete-inventory sheet, exact-key reuse, duplicate dispatch and reconnect journeys (including an empty-account-only bypass); restored controls pass. Evidence uses synthetic storage/network boundaries, not physical Android or live backend association. All mandatory commit/push hooks passed; fresh GitHub CI is pending. - Bounded review repair at `d3cc0003f`: incomplete secure-storage enumeration now blocks automatic identity generation while explicit known-key reads retain their fallback; declined/failed onboarding links release the queue; HTTP 429/5xx keeps Retry regardless of response encoding. Default app-gate coverage exercises a bind link followed by ordinary community entry. Focused checks: configured domains 47 passed; default 38 passed, 9 hosted-only skips. Removing the three production fixes in an isolated source/Git/build copy fails the identity-resolution, declined/failed queue, and Retry journey assertions; clean and restored controls pass. Storage and HTTP failures are synthetic; physical Android and live outage behavior were not exercised. Published after all mandatory commit/push hooks passed (mobile analysis/tests, branch-skew and file-size gates); fresh GitHub CI remains pending. - Existing whole-PR source review cleared the reconnect defects at `fb15d5b82`. - Domain-policy increment: focused environment, entry, app-gate, pairing and onboarding journeys pass with empty and configured domains. Existing pairing provider/page tests pass. Changed Dart files analyze cleanly. - Isolated source/Git/build mutation: forcing paired credentials through hosted login fails the default-build journey; clean and restored controls pass. CI now runs configured-domain journeys in addition to the default-build suite. - Integrated main through `5b433d929` at `0067c069c`, including its pinned Flutter upgrade. Preserved the PR welcome UI with the updated transition API and added Material surfaces around onboarding selection/consent rows. Focused post-merge runs pass in both configurations; all mandatory local push gates passed (mobile analysis/tests, Rust tests, desktop-native checks, branch-skew and file-size checks). - Merge-review repair at `a315bce11`: focused identity/storage/admission and widget journeys pass, including account switching with an empty or already-bound second account, explicit reuse, and self-hosted removal/rejoin with another key. Default-domain journeys pass too (hosted-only cases intentionally skip there). - Isolated source/Git/build mutation checks: bypassing account scoping, reuse consent, pending-key retirement, or recovery inventory reconciliation fails the relevant journey/invariant assertions; clean and restored controls pass. - Native `RunnerTests/IdentityFilePluginTests`: both tests pass on the iPhone 18 Pro iOS 27 simulator with an isolated app identifier. At `24a0dcaac`, the picker journey seeds residue in Library/Caches, matching path_provider_foundation, and verifies plugin startup removes it while preserving an unrelated file. The earlier tmp-only fixture did not exercise the actual export location. This is synthetic native cleanup/picker evidence, not a real terminated-share or live account round trip. - Follow-up: Caches and tmp cleanup; fallback to individually known identity slots when Android bulk enumeration fails; explicit replacement of a refused self-hosted key preserves its original before swapping the retry slot. Configured-domain journeys/invariants: 34 passed; default: 31 passed, 3 hosted-only skips. Isolated enumeration/retry mutations fail with passing controls. Bulk-read fallback preserves but cannot enumerate arbitrary other-account slots until bulk reads recover. - Configured-domain CI exposed a stale pairing-status assertion after account scoping. The repaired test checks the admission mismatch, preserved account/transfer keys, and no admitted community. The configured-domain CI selection passes locally (56 tests); removing the production mismatch guard fails the updated test, with clean/restored controls passing. This is synthetic coordinator evidence, not physical QR acceptance. - Final review repair (`40e1e6101`): native iOS export creation uses atomic complete file protection; normal and restart cleanup remain. Account/policy/claim HTTP uses one 30-second total deadline with request abort and body cancellation. Removed the unrelated NIP-FA spec edit. - Focused account/admission/export tests: 25 pass; configured-domain account/admission/onboarding journeys: 33 pass. Isolated deadline and native-dispatch mutations fail, with passing clean/restored controls. Native export/picker tests: 2 pass on iOS 27 simulator. The real file-protection attribute assertion is physical-device-only because simulator provides no Data Protection attribute; locked-device protection and interrupted real sharing have not been observed. - Opt-in UI: configured-domain CI selection passes (57 tests); default selection passes (7 tests, 10 hosted-only skips); URL-only plus whitespace/empty domains passes (6 tests, 9 hosted-only skips). Changed Dart files analyze cleanly. Independent mutations that unconditionally initialize the coordinator in the app gate, welcome entry, or link form fail the default journey; clean/restored controls pass. - Native welcome screens exercised on iPhone 18 Pro / iOS 27 simulator in default and configured builds: default exposes community link / QR / pairing code only; configured build additionally exposes Builderlab connection and community creation. No live hosted login was exercised in this check. - Delivery at `e48fe73a9`: all mandatory push hooks passed (full mobile analysis/tests, Rust tests, desktop-native checks, branch and file-size checks). GitHub checks had not yet populated at the immediate post-push snapshot. ## Review disposition | Feedback | Disposition | | --- | --- | | Explicit self-hosted entry under unreadable inventory, duplicate invite dispatch, reconnect cross-account binding ([entry](https://github.com/block/buzz/pull/8375#discussion_r4318421622), [queue](https://github.com/block/buzz/pull/8375#discussion_r4318421640), [reconnect](https://github.com/block/buzz/pull/8375#discussion_r4318455512)) | Repaired at `66a12ac92`; evidence above. Reconnect refuses unproven ownership rather than silently establishing a binding. | | Incomplete Android identity inventory, stranded deep-link queue, transient HTTP retry classification ([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5576864143)) | All three repaired in `d3cc0003f`; focused journeys and isolated mutation evidence above. | | Account cross-link, incomplete recovery inventory, committed invite checkpoint, pending local key retirement/replacement | Repaired in the preceding commits; journey and mutation evidence above. | | iOS interrupted key export ([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575253252)) | Native cleanup plus complete protection at creation implemented. Physical-device lock and real interrupted sharing acceptance remains pending. | | Trickle responses bypass idle timeout; unrelated NIP-FA edit ([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575764556)) | Total request deadline/abort implemented; spec edit removed. | | Production domains rejected | Ordinary entry now needs no Builderlab configuration. Opt-in account-required domains must still use supported community mappings. | | Lost Android Keystore recovery | Backup exclusions prevent the reviewed stale-restore scenario; genuine key loss still has no in-app recovery/reset and remains deferred. | | Native secp256k1 dependency question | Obsolete against the current base: upstream C integration landed in #8398; no package diff remains here. | | Operator membership endpoint contract | Documentation now states the operator chooses the pubkey; no end-user session binding is implied. Additional handler-level coverage is optional follow-up. | | Optional Android partial document cleanup/activity retention; local work after backup cancellation | Follow-up hardening, not claimed implemented. Cancellation prevents remote backup upload. | | Semgrep crypto inventory notices | Informational inventory, not demonstrated defects. | ## Remaining draft gates Native QR/browser-return acceptance remains unverified for this revision. Optional Builderlab onboarding still needs backend backup-status and joined-community routes, recovery policy/configuration, and real backup/recovery/reconnect acceptance. The empty-domain build removes these services as prerequisites for ordinary pairing; it does not make the optional hosted flows backend-ready. Human acceptance and current CI are still required before merge. Review dispositions retained: production auth-domain configuration must use supported community mappings; enabling `builderlab.xyz` does not add support for `buzz.block.builderlab.xyz`. Recovery after genuinely losing an Android Keystore key remains a follow-up, not a newly implemented capability. Human acceptance steps: build once without `BUZZ_AUTH_DOMAINS` (including with a previously saved account) and confirm no Builderlab controls/restoration while ordinary link and QR/code entry work. Build with supported domains and confirm connection/creation appear; exercise browser return and live backup/recovery/reconnect. On physical iOS, exercise export and interrupted sharing/locked-device protection. Record results before marking review complete. --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@wes.communities.public.builderlabstaging.xyz>	2026-10-19 15:46:58 -06:00
