Enterprise plugin sync stuck in 'in_progress' for over 26 hours

Bug Description

Enterprise plugin sync has been stuck in in_progress status for over 26 hours with no errors reported.

Environment

• Claude Code Enterprise (managed plugin marketplace)
• Plugin source: GitHub private repository

Steps to Reproduce

1. Register a GitHub repository as an Enterprise plugin
2. Trigger plugin sync (or it gets triggered automatically on push)
3. Sync starts but never completes

Observed Behavior

The sync remains in in_progress indefinitely. The API response shows:

{
    "id": "marketplace_XXXXXXXXXXXX",
    "sync_status": "in_progress",
    "sync_started_at": "2026-03-10T08:58:40Z",
    "sync_ended_at": "2026-03-10T04:47:03Z",
    "sync_errors": null
}

Key observations:

• sync_started_at (08:58 UTC) is after sync_ended_at (04:47 UTC), meaning the previous sync completed but the current one has been running since then
• sync_errors is null — no error reported, just hanging
• As of 2026-03-11, the sync has been stuck for 26+ hours

Expected Behavior

• Sync should complete within a reasonable timeframe (minutes, not hours)
• If sync fails, sync_errors should report the reason and sync_status should reflect the failure
• Ideally, there should be a way to cancel/retry a stuck sync from the Enterprise admin console

Questions

1. Is there a way to manually cancel and re-trigger a stuck sync?
2. Would deleting and re-registering the plugin resolve this? Would that affect existing users who have the plugin installed?
3. Is there a timeout mechanism for stuck syncs?

Workaround Attempted

• The repository was updated with fixes (frontmatter YAML parsing issues were resolved and merged to main), but the sync remains stuck from before those changes.
