isDead
Whether --prune-acks deletes this entry.
AckStatus.inert is deliberately kept: its fingerprint still matches, so it is a valid ruling about the current text that simply is not needed today. Deleting it would throw away a judgement someone actually made.
Implementation
bool get isDead =>
status == AckStatus.lapsed ||
status == AckStatus.orphaned ||
status == AckStatus.invalid;
