ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR requires human approval — This adds background agent-widget refreshes with scoped credentials and stale-state handling. It also introduces two static-analysis suppressions for node:crypto imports that require human review. You can add or adjust custom eligibility rules. Learn more. |

Merge Risk:

-
Widget aggregation and replay behavior still have correctness risks, while native generated-source changes can silently regress widget functionality; resolve these before merging.
Security Architecture Review
-
Security architecture risk: 🟡 Moderate · up to
6b76eBackground 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.

The widget refresh rewrite dropped main's guard around dismissEnded. Binaries built before that native method throw there, which aborted active Live Activity token registration and cloud sign-out cleanup. Restore the guarded cleanup on both paths.

…sland Keep main's pruned test suites and port only this branch's own cases into them, including main's ended-card cleanup regression test. Keep the quiet compact Working glyph from main, but show the "Last observed" label instead of the glyph for retained or expired observations. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The widget refresh rewrite reverted main's Effect.fn conversion of the registration helpers, dropping their spans. Restore the same span names and trace the new widget snapshot refresh too. Read Date.now lazily so the live widget observer follows the same clock as the rest of the module. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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. Widget-only recipients are included even when both notification options are off. Unchanged replay rows do not enqueue another refresh; changed replay rows still do. Complete relay snapshots release empty disconnected observations, widget credential claims preserve the current install, and snooze-expiry timers republish hidden threads without another event. The change includes the relay migration, generated extension entitlements, and native fingerprint inputs. It requires a compatible native rebuild and relay deployment.
