Scheduled tasks

This ordinary external package owns task definitions and scheduling rules. Its headless handlers use private KV and bounded host transactions to register schedules, event handlers, and concurrency groups. The callback invokes the public sessions.start capability, which atomically creates a conversation and admits its first turn through the existing Node command ledger and Agent queue.

completion: "turn" holds the dispatch slot through model execution, tools and approvals. Closing the plugin page does not stop execution. Removing a task cancels its unstarted deliveries, not running conversations. History reads the original admission receipt; unknown effects are never automatically replayed.

Handlers: list, save, remove, run, history, queue, cancel, stop, projects. Task and queue revisions are decimal strings. New task IDs may be omitted; the host invocation ID provides a stable identity. A null configuration resolves Node defaults at execution admission. Project catalog access is explicit and does not expose conversations or private scratch worktrees.

The desktop entry owns its Kit page, forms and locale resources. Read-only views share package queries with the headless entry; writes use durable host callbacks. History opens the existing host conversation route. Stopping a run is confined to the original turn admitted by this package's dispatch job.

New profiles install this as an ordinary default package. Existing profiles are not migrated or rewritten, and restarting never reinstalls a removed package.
