iOS: always show New Task, warn in composer when no Mac is connected - #10476

supportsTaskComposer returns false whenever no Mac connection is live, so the Compose Task button disappears while the phone is offline or between reconnects instead of opening the composer with a warning. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
supportsTaskComposer treated the foreground Mac's capability snapshot as the only signal, and that snapshot is empty whenever no Mac connection is live, so the Compose Task button vanished while offline or between reconnects. Now any connected Mac (foreground or control secondary) advertising workspace.task_create.v1 shows the entrypoint, a fleet of connected Macs that all lack it still hides it (the remote kill switch keeps working), and with zero connected Macs the entrypoint stays visible. The composer sheet renders a non-blocking 'No Mac is connected' banner via the new hasAnyConnectedMac signal so the missing connection is explained instead of hidden.

It remains available without a connection and displays a localized, non-blocking warning when live state has no connected Mac. ChangesTask Composer Connection Awareness
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR changes task-entry visibility and connection warnings; if secondary connection records outlive their live sessions, the app could show the entrypoint or suppress the no-Mac warning based on stale state. This is a bounded merge-readiness risk that warrants owner awareness or follow-up, but no supplied evidence indicates a release-blocking failure. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR keeps the iOS New Task entrypoint visible while offline, derives availability from all connected Mac capability snapshots, and adds a localized offline warning.
Confidence Score: 5/5The PR appears safe to merge. No blocking failure remains. Important Files Changed

- Around line 129-144: The test suite for supportsTaskComposer lacks coverage of
secondaryMacSubscriptions. Add tests that populate secondaryMacSubscriptions
with a connected secondary Mac both advertising and not advertising
Self.taskCreateCapability, verifying the property returns true when supported
and false when a connected secondary Mac lacks it.
- Around line 122-151: Update performSecondaryMacSubscriptionEstablishment and
enqueueSecondaryWorkspaceRefresh so every failure after insertControlIfAbsent,
including .superseded and .transientFailure outcomes and transient authority
failures, retires the exact inserted subscription. Ensure
secondaryMacSubscriptions no longer retains non-live clients, while preserving
successful subscription handling.

The Compose Task button was gated on
supportsTaskComposer, which only read the foreground Mac's live capability snapshot. That snapshot is empty whenever no Mac connection is live, so the button disappeared while offline or between reconnects, and a capable secondary Mac could not show it either.Now any connected Mac (foreground or control secondary) advertising
workspace.task_create.v1shows the entrypoint. A fleet of connected Macs that all lack the capability still hides it, so themobile-task-composer-enabled-releaseremote kill switch keeps working. With zero connected Macs the entrypoint stays visible and the composer shows a non-blocking orange "No Mac is connected. Open cmux on a Mac to start this task." banner (newhasAnyConnectedMacstore signal). Submission to an offline Mac keeps its existing failure path.Commit 1 adds the failing regression test (fresh store must keep the entrypoint visible), commit 2 the fix. Localization audit: one new key
