The hourly sweep pruned canonical acknowledgement records after 24 hours even while their incidents remained active. Preserve active tracking identities as the ordinary cleanup already does, so a short recovery and recurrence retain the operator decision. Keep inactive expiry, legacy timestamp fallback and explicit unacknowledgement unchanged. Validate manual and automatic acknowledgements through provider-native pool incident reconciliation, JSON and durable checkpoint restart, dispatch counters and retention bounds; update the alert contract in the same commit.
