Schedules tab shows "No scheduled tasks yet" while scheduled tasks run correctly in the background

App version: Claude desktop (Cowork) 1.12603.1, CCD 2.1.170, Windows 11 (build 10.0.26200)

Summary:
The Schedules panel in the sidebar displays "No scheduled tasks yet" even when a valid, enabled scheduled task exists, runs on its cron schedule, and is fully visible/manageable through the scheduled-tasks MCP tool. This affects both a pre-existing task and a brand-new task created fresh through the normal creation flow.

Steps to reproduce:

1. Have (or create) a recurring scheduled task, e.g. via the scheduled-tasks tool or the app's own schedule creation flow — cron 0 19 * * *.
2. Confirm the task fires correctly: check logs/main.log for [CCDScheduledTasks] Spawning new session for scheduled task ... and [CCDScheduledTasks] Confirmed task run for: ... — task runs as expected.
3. Open the Scheduled section in the sidebar.

Expected: The task appears in the list with its schedule, enabled state, and next/last run time.

Actual: Panel shows "No scheduled tasks yet," regardless of:

• Whether the task predates or postdates the current app session
• Which project the task's cwd is set to (tested with a task tied to the currently active project — still not shown)
• Full app restart (quit from tray, not just window close)
• Recreating the task from scratch via create_scheduled_task rather than editing an existing one

**What we confirmed is not the cause (data layer is healthy):**
The task registry at AppData\Roaming\Claude\claude-code-sessions\<projectId>\<sessionId>\scheduled-tasks.json correctly reflects the task's state (id, cronExpression, enabled, filePath, cwd) at all times, matching what list_scheduled_tasks returns. Two backend log namespaces exist — [CCDScheduledTasks] (dispatch/execution — works correctly) and [ScheduledTasks] (appears tied to the UI) — both log Reset → Initialized with matching accountId/orgId on every app launch, but the panel never populates.

Suspected trigger: Started after some folders under this app's AppData directory were unexpectedly deleted (exact folders unknown — was not captured before deletion). The backend scheduler state survived (either regenerated or read from ~/.claude/scheduled-tasks/*/SKILL.md directly), but whatever the Schedules panel's UI-side data source is did not recover.

Impact: Users with this issue cannot view, edit, pause, or delete scheduled tasks from the UI at all — the only workaround is managing them via the scheduled-tasks MCP tool through a chat session.
