Module changes 

Best-effort, state-scoped invalidation hints. SQLite and session files remain authoritative. The first subscriber temporarily hosts a hub; there is no daemon and writers never elect one.

Structs

Subscription

Register before reading the baseline. Dirties arriving during that read stay queued. Drop requests cancellation; await Self::close before removing the subscribed state.

Enums

Change

Hints carry no records, credentials, scheduler decisions or remote-store events.

Changed

What the hints since a reader’s last read say it must read again: nothing, these Runs, or everything. Session hints are not about the state database and change nothing here.

Constants

RECONCILE

Reconcile missed commits and database replacement without reloading idle snapshots.

Functions

drain

Drain short-lived commands centrally. Only bounded hints are sent; a failed delivery is safe.
