Phase 2 continued. evaluateCanonicalStatefulAlert (health assessments,
posture thresholds, change thresholds — ZFS pool state, backup and
snapshot age, docker update-delay states) no longer reconstructs
previous state from the pending-since maps: the reducer core owns the
transition via the shared Match predicate, with the legacy maps kept as
read-only mirrors. The family keeps its occurrence-stamping semantics
(observation time or the caller's override such as a backup timestamp)
and its refire-without-new-history behavior, now driven by the core's
refire events.
Manual clears now record a resolved occurrence in the core (Forget
takes the clear time), matching the manager's recently-resolved
behavior, so a quick re-fire after a manual clear reactivates the same
occurrence instead of duplicating history — with the ack entering its
retention window. statefulPreviousState survives only until the last
mirror deletion.
