…kground error expo-widgets stopped applying containerBackground for us, and the home-screen widget never got a createWidget layout. iOS 17 then showed "Please adopt containerBackground API" instead of agent activity. Adopt the modifier on the home-screen views, register the widget layout, and publish snapshots from the Live Activity refresh path. While the app is foregrounded, regular widgets follow complete live environment shells and reconcile them with relay snapshots scoped to the remaining environments. Rebased onto main as a single commit. Widget publishing goes through the platform-split agentLiveActivity module so non-iOS builds never import the widget, the Live Activity banner keeps the system glass tint and hierarchical foregrounds, and environments switched off in Settings no longer own widget rows.

Suggested reviewers: Merge Risk: 🔵 Low · up to The widget refresh feature is broadly sound. A few edge cases can leave a widget credential unregistered, make the relay retry a push token that can never succeed, or let an update reach builds whose native code does not match. These can be fixed as small follow-ups. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Background access is narrowly scoped, but sign-out can lose the request that revokes it. If both cleanup attempts fail, a previously copied credential may continue reading the account’s linked agent activity. This does not grant command execution or general account access.

Add AgentWidgetCredential.swift to the fingerprint sources.
withAgentWidgetRefresh.cjs copies modules/t3-native-controls/ios/AgentWidgetCredential.swift into ExpoWidgetsTarget, but extraSources does not list that file. The native module autolinking may already fingerprint the file for the main app target. That is not established for the extension copy. If the Keychain query changes, the fingerprint must change so that OTA updates do not reach binaries that are incompatible.

Make store handle an existing Keychain item.
SecItemAdd returns errSecDuplicateItem when an item already exists for this service and account. token(identity:) calls clear() first, and clear() calls remove(). remove() ignores the SecItemDelete status. Suppose the delete fails, or the extension's read() fails while the item still exists, for example because of a protection-class mismatch. In that case, store returns false on every attempt, and the widget credential can never register. Delete the item before adding it, or fall back to SecItemUpdate when the status is errSecDuplicateItem.

Treat DeviceTokenNotForTopic as a permanent widget token failure.
process clears widgetPushToken only for status 410, BadDeviceToken, or Unregistered. ApnsDeliveries.ts (PERMANENT_APNS_TOKEN_REASONS) also treats DeviceTokenNotForTopic as permanent. A widget token can produce this reason, for example after a bundle-ID or topic mismatch between app variants. In that case this branch returns ApnsHttpRequestError. processSignedJob then maps it to WidgetRefreshDeliveryError, and the queue retries the job up to maxRetries: 5 before it sends the job to the dead-letter queue. Each later publish queues a new job for the same bad token. The token is never cleared.

The iOS Agent Activity widget could render blank and keep showing an old “Working” snapshot after T3 closed. This change embeds the native layouts and lets the widget extension fetch current linked agent activity directly from the relay, independently of the app’s JavaScript runtime.
The relay registers an install/account-scoped read capability, stores its hash, and queues WidgetKit refresh pushes when agent activity changes. On iOS 26+, the extension registers its WidgetKit push token and receives quiet refresh requests. Scheduled native reads request another refresh after five minutes; iOS controls the actual timing and budgets both mechanisms. Successful reads renew freshness, including unchanged results. After an hour without a confirmed relay read, unfinished rows become out of date; Done and Failed outcomes stay intact. Direct-only observations retain their ten-minute deadline.
Foreground reconciliation preserves live environment precedence, handles older relay responses with an unavailable count when needed, and clears previous-account content. The native configuration survives app suspension. The read capability is stored in the shared Keychain. Sign-out and identity changes clear cached rows and request capability revocation independently of the former Clerk session; existing device unregistration remains in place. Widget refreshes are enqueued before other target deliveries so an Android delivery failure cannot suppress them. The change includes the relay migration, generated extension entitlements, and native fingerprint inputs. It requires a compatible native rebuild and relay deployment.
Replaces #14608, which was accidentally closed again despite its
