An unreadable storage right after an agent restart read the off-site tier
DUE (the in-memory record was empty). The newest success per tier is now
kept on disk and read ONLY when the storage cannot be read: fresh -> not
due, older than the cadence -> due, none -> due (unknown) as before. A
storage that answers stays the ground truth.
Ships with v0.150.0 after the 2026-10-07 read-back; nothing delivered.
