Rejected active-alert writes still reached history, firing events and
notification dispatch. Make admission explicit across detector and restore
paths so repeated suppressed observations cannot create those side effects.
Reconcile restored alerts when persisted resource policy attaches at startup,
reconcile again after native aliases become canonical, and refresh shared
state before those alerts reach clients.
Preserve occurrence identity when retained alerts re-fire, including durable
history reconstruction and delayed lifecycle replay.
Keep retained table and card components mounted when scrolling shifts the
visible window, so policy editors do not lose unsaved state. Show actual
future maintenance times and the paused-attention effect.
Keep synthetic host machine identities stable across restarts so saved
operator policy remains attached during verification.
Qualify server update and rollback instructions by helper ownership, and
stop signed installer recipes before execution if a download or signature
check fails.
