[Bug]: Thread list shows no tag for a thread with a bound scheduled task (looks idle)

[BlackPhoenixSlo]

Before submitting

• I searched existing issues and did not find a duplicate. (Related, but different: Scheduled task settings do not show the destination thread #26641, where the settings editor doesn't show a task's bound thread.)
• I included enough detail to reproduce or investigate the problem.

Area

Mobile app: thread list (Threads tab)

Steps to reproduce

1. In a thread, have the agent launch a few top-level threads with t3_thread_launch, then call schedule_task with {"type":"interval","everyMs":3600000}. The task binds to that thread by default.
2. Let the agent's turn finish. The thread's status becomes completed.
3. Open the Threads tab on mobile.

Expected behavior

The row shows that the thread still has future work coming, for example a "Scheduled · next 01:09" tag. The waiting rows nearby get a tag, and a thread with an enabled bound scheduled task matters just as much.

Actual behavior

The row shows only the relative time ("3m"), so it looks like a finished, idle thread. It sits in the active list with nothing to tell it apart from threads that have nothing coming. Meanwhile:

• list_scheduled_tasks returns an enabled task with boundThreadId set to this thread, nextRunAt: 2026-10-30T00:09:33Z and lastRunStatus: never.
• t3_thread_read returns status: completed, pendingRequestCount: 0, snoozed: false. Nothing in the thread payload refers to the bound task.

Searching the repo, nextRunAt is only used in the mobile app under features/settings/ (SettingsScheduledTasksRouteScreen.tsx, scheduledTaskPresentation.ts). The thread list doesn't seem to read scheduled tasks at all. On the web, ThreadAutomationsPanel.tsx shows them, but only after you open the thread. (This is inferred from a code search; I haven't traced it at runtime.)

Impact

When I orchestrate from my phone, I can't see which threads are parent threads that will wake up on a schedule and which are just done. It's easy to settle or forget a thread that still has hourly checks scheduled.

Version or commit

Desktop app 0.1.2 (T3 Code Beta) on macOS, with the current iOS mobile client.

Environment

macOS 15 (Darwin 24.6) host, iPhone client, Claude provider threads.

Workaround

Open each thread, or go to Settings → Scheduled tasks and match the tasks to threads by hand.
