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 After an hour without a confirmed relay read, unfinished rows become out of date; Done and Failed outcomes stay intact.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 triage:keep-open label. Julius added that label at 17:57 UTC and asked us to continue on the old PR so the dot would not close it; it was closed again at 19:04 UTC with the label still present. This PR carries forward the implementation, review fixes, and evidence previously validated at a3407096998d7f2d3701d0e726f32bc2456c9c36. It is now rebased onto main at 4df84a7d03, with relay test conflicts resolved and local widget activity adapted to the new orchestrator’s V2 thread shells. It continues #6464.

Validation

  • After the latest rebase: 263 focused tests passed across 12 files; mobile, relay, client-runtime and contracts typechecks, scoped formatting/lint and native Swift behavior checks passed. The widget migration now follows main's latest relay migration and preserves its schema. Current head: ceba16d1e17482dfd3b8f362c1e224d8286a126a. CI runs separately on this commit. No new device verification was performed during this rebase.
  • Before the rebase, all CI checks passed in fix(mobile): keep agent widgets updated in the background #14608, including mobile native static analysis, lint, typecheck, build, and tests.
  • 296 focused tests passed across 15 files covering mobile registration/reconciliation/layouts/timelines, relay refresh/registration/publication/APNs delivery, HTTP handlers, client requests, and contracts.
  • Native Swift behavior checks passed for unchanged-result renewal, source reconciliation, expiration, terminal preservation, and property-list storage.
  • Scoped formatting/lint and mobile, relay, client-runtime, and contracts typechecks passed.
  • A fresh compatible native build succeeded on iPhone 18 Pro Max, iOS 27.0. With T3 terminated and Metro stopped, real native scheduled reads changed isolated test agents from Working → Approval → Done. Reads at 17:16:39 and 17:21:59 UTC fetched the new states; the widget stayed fresh beyond the app’s original ten-minute deadline.
  • The scheduled-update recording predates the final rebase and review fixes. It demonstrates native background fetching, not the later Keychain or cleanup changes. Review fixes passed 114 focused relay/contracts tests, 91 mobile coordinator tests, and native Swift cleanup checks. Scoped typechecks/lint passed. CI found and corrected a Swift collection-alignment violation in the Keychain helper. A credential-only edit was also verified to change the Expo fingerprint through its automatically tracked native module directory. The new iOS build containing shared Keychain access succeeded. Cross-target Keychain reads and native sign-out behavior have not yet been observed at runtime: the simulator host disconnected immediately after the build. The Swift cleanup checks cover cached timeline erasure and preparation of the capability-revocation request.
  • The recording uses synthetic agent states and the production native widget/relay refresh service with isolated persistence. It does not exercise real agent approval or input workflows. APNs request construction, routing, token revocation, and queue handling are tested; real WidgetKit push delivery and the requested two-thread push sequence remain unverified. Real push-path recording proof remains outstanding.

📝 Walkthrough

Walkthrough

This change adds iOS Agent Activity home-screen and accessory widgets. Mobile code reconciles local shell activity with relay snapshots and publishes widget state. The relay adds widget credentials, refresh and revocation APIs, and APNs widget pushes. The iOS extension fetches and caches activity, then marks unfinished activity stale when its timeline expires.

Changes

Agent Activity Widget Refresh

Layer / File(s) Summary
Relay contracts and scoped snapshots
packages/contracts/src/relay.ts, packages/client-runtime/src/relay/managedRelay.ts, infra/relay/src/agentActivity/MobileRegistrations.ts, infra/relay/src/http/Api.ts, related tests
Widget registration and refresh contracts are added. Activity snapshot requests can exclude environment IDs, and the client includes those filters in the request and DPoP proof.
Relay credentials and refresh API
infra/relay/src/persistence/schema.ts, infra/relay/migrations/postgres/..., infra/relay/src/agentActivity/Devices.ts, infra/relay/src/agentActivity/AgentWidgetRefresh.ts, infra/relay/src/http/Api.ts, infra/relay/src/worker.ts, related tests
Device storage gains widget access-token hashes and push tokens. The relay implements capability-authorized refresh and revocation, and exposes the widget API.
Widget push delivery
infra/relay/src/agentActivity/AgentActivityPublisher.ts, infra/relay/src/agentActivity/ApnsClient.ts, infra/relay/src/agentActivity/ApnsDeliveries.ts, infra/relay/src/agentActivity/apnsDeliveryJobs.ts, infra/relay/src/worker.ts, related tests
Activity publication queues widget refresh jobs. Delivery processing sends widget pushes through APNs and handles widget delivery errors and invalid push tokens.
Local activity collection and reconciliation
apps/mobile/src/features/agent-awareness/liveWidgetActivity.ts, apps/mobile/src/features/agent-awareness/liveWidgetActivity.test.ts
Mobile code collects activity from live environment shells, retains unconfirmed observations, and reconciles local rows with relay snapshots. It orders and limits displayed rows and reports an unavailable count when the snapshot scope does not support a count.
Mobile publication and lifecycle
apps/mobile/src/features/agent-awareness/remoteRegistration.ts, apps/mobile/src/features/agent-awareness/agentWidgetRefresh.ios.ts, apps/mobile/src/features/agent-awareness/agentWidgetRefresh.ts, apps/mobile/src/features/agent-awareness/agentLiveActivity.ios.ts, apps/mobile/src/features/agent-awareness/agentLiveActivity.ts, related tests
Registration configures widget refresh and publishes reconciled content. Observation follows account and app lifecycle changes, and refresh results are checked against concurrent session or scope changes. Local-work and Live Activity flows also update the widget.
iOS extension setup and background refresh
apps/mobile/app.config.ts, apps/mobile/plugins/withAgentWidgetRefresh.cjs, apps/mobile/modules/t3-native-controls/ios/*, apps/mobile/plugins/widget/*, apps/mobile/fingerprint.config.js, docs/user/mobile-notifications.md
The build plugin registers and wires the widget extension. Native code stores its credential and configuration, fetches relay activity, and builds timelines for scheduled and push-triggered updates.
Widget layouts and freshness
apps/mobile/src/widgets/AgentActivity.tsx, apps/mobile/src/widgets/agentActivityTimeline.ts, apps/mobile/src/widgets/*test.ts, apps/mobile/src/features/showcase/showcaseAgentActivity.ts
AgentActivity renders home-screen and accessory layouts alongside its Live Activity presentation. Timeline expiration marks unfinished rows stale, while unavailable counts and idle states receive distinct labels.

Merge Risk

Merge Risk: 🔵 Low · up to 6b76e

The widget refresh feature appears wired correctly in this update. Three earlier concerns remain open: widget credential storage can fail if a Keychain item already exists, native fingerprinting may miss a copied credential source, and one APNs rejection reason causes repeated retries instead of clearing the token. Each is bounded and should be followed up, but none blocks merge on its own.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 6b76e

Background access is limited to the registered account’s activity, but sign-out cleanup has two weaknesses: failed revocation can leave a credential usable, and an overlapping refresh can restore previous-account content. Secure credential storage and account-scoped reads limit the exposure.

Retained concerns

  • Medium · security · inferred: Offline or interrupted sign-out can leave the new read capability active indefinitely. Native cleanup removes the credential and URL before sending a single asynchronous DELETE; failure only logs, leaving no stored material for a later retry. Normal device unregistration can also fail without durable recovery. The widget read path has no expiry or former-session check, so a previously copied bearer can continue reading that account’s enabled linked-environment activity until successful revocation, device deletion, or credential replacement. Local credential deletion protects the normal widget but does not invalidate another bearer holder.
  • Medium · security · inferred: An old-account native refresh can restore cached activity after sign-out or account switching. Its callback checks the current token and URL, then parses and writes the timeline separately. Cleanup in the independently running app can remove credentials and cached rows after that check but before the write. The resulting entries contain no account identity, and cached rendering does not validate credential ownership. The token/URL guard and JavaScript generation checks stop many stale completions, but do not serialize this cross-process commit with cleanup. Actual reproduction of this interleaving remains unverified.

Security review details

Security Blast Radius

  • observed — A bearer holder can access the registered account’s aggregate activity across its non-revoked, live-enabled linked environments, not arbitrary accounts or environments. The examined capability endpoints permit snapshot reads, push-token binding, and self-revocation; they do not expose agent-execution authority.

Security Findings and Attack Paths

  • inferred — If a capability was copied before sign-out and both network cleanup paths fail, its holder can continue authorized activity reads independently of the former login session. This does not itself provide a way to obtain the credential.
  • inferred — An old refresh callback that passes ownership validation immediately before cleanup can subsequently repopulate the shared timeline. Cached rendering can then expose previous-account activity to someone viewing the device after sign-out or switching accounts.

Trust Boundaries and Controls

  • observed — Mobile registration requires authenticated account identity and DPoP validation. Widget access deliberately uses separate bearer authority, with identity derived from the stored device rather than caller-supplied account IDs. Activity reads join active environment links, and queued widget jobs undergo signature verification and device/token revalidation before delivery.

Resilience and Maintainability Implications

  • observed — JavaScript registration checks session generations before applying asynchronous success, native configuration checks the current credential, and revocation clears both capability and push-token state. Delivery skips targets that no longer match, while APNs invalidation clears only the matching current push token. These controls bound stale-operation effects but do not make native cache cleanup atomic or revocation durable.

Hardening Proposals

  • proposed — Preserve pending revocations securely until acknowledged, with idempotent retry after interruption. A bounded server-side capability lifetime could limit residual authority when cleanup cannot complete.
  • proposed — Bind cached timelines to an account generation and serialize commit versus cleanup across the app and extension. Reject mismatched entries during rendering so a stale write cannot become visible after an identity transition.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

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.

Proposed fix
-    return SecItemAdd(query as CFDictionary, nil) == errSecSuccess

Update AgentWidgetCredential.store to handle an existing Keychain item: when
SecItemAdd reports errSecDuplicateItem, update the existing item’s token data
and accessibility using the existing query, and return whether the final
Keychain operation succeeded.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

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.

🐛 Proposed fix
       if (
         result.status === 410 ||
         result.reason === "BadDeviceToken" ||
-        result.reason === "Unregistered"
+        result.reason === "Unregistered" ||
+        result.reason === "DeviceTokenNotForTopic"

lines 207 - 234:
Update the permanent-token failure condition in `process` to include
`DeviceTokenNotForTopic`, so it clears the matching `widgetPushToken` instead of
returning an `ApnsHttpRequestError` and retrying the job.

🟡 Medium agent-awareness/remoteRegistration.ts:596

After an empty relay snapshot succeeds, publishReconciledWidget still includes its old relayWidgetConfirmedAt in the minimum deadline, so fresh shell updates cannot extend the widget’s freshness. Once that relay read is ten minutes old, newly observed running or approval rows are immediately shown as expired; include relay freshness only when the snapshot contributes displayed state, or track freshness deadlines per source.

🟡 Medium 20261006011848_agent_widget_refresh/snapshot.json:907

This snapshot omits relay_managed_endpoint_allocations.tunnel_released_at, so it no longer matches the database after the preceding migration and subsequent Drizzle generation treats the existing column as new. Preserve the column here and set prevIds to the preceding migration’s snapshot ID.

…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.
