Do we really want to stop everything if a single actor fails on this basis?

If an actor panics, the coordinator catches the error in coordinator.next() and logs it, but the system keeps running without the actor. Though know that you mentioned this, probably the best would be to return an specific error for this Db fail case.

_ is type Result<(), SendError<ActorRequest>>. Are we sure we don't want to be handling that error here?

Same with let _ = ack_rx.await; below

LGTM just a few questions on errors we don't handle

First task of #1694
mpsc<Arc<MempoolEvent>>channels withArc<Notify>. The DB is already the source of truth (since chore(ntx): replace in memory with sqlite database #1662), so actors only need a "re-check your state" signal and not the event payload. This removes allSendErrorhandling, failed-actor cleanup, and thesend()helper from the coordinator.TransactionInflightmode, actors now query the DB (is_transaction_resolved) to check if their awaited transaction was committed/reverted, sinceNotifydoesn't carry payload.ActorRequestenum over onempscchannel.NotesFailedcarries a oneshot ack to prevent a race condition where the actor could re-select notes before failure counts are persisted (context).CacheNoteScriptremains fire-and-forget.
