Task supervisor for async operations in Arcana.

Add to your application's supervision tree:

children = [
  MyApp.Repo,
  Arcana.Embedder.Local,
  Arcana.TaskSupervisor
]

This enables supervised async operations in the Arcana dashboard (evaluation runs, test case generation, maintenance tasks) with:

  • Graceful shutdown during deploys
  • Visibility in Observer/LiveDashboard
  • Proper crash logging with $callers metadata
