R-81 merged every backup signal into one 'newest' against a single 26h limit.
backupStaleAfter's own comment recorded why that stops being right under a
weekly offsite tier. Each tier is now judged against its own threshold;
R-81's structure (three verdicts, anchored absence, distinct reasons) and its
boundary test are preserved intact.
- offsiteBackupStaleAfter = 8d (7d cadence + headroom); backupStaleAfter keeps
26h and now names the HOST tier only
- splitTiers / assessTier / newestBackupEvidenceByTier
Slice-A.4 rule implemented: a PBS-targeted vzdump appears in BOTH arrays, so
classification is by TARGET TYPE (target_id -> storage_targets[].name -> type),
never by array membership — otherwise a PBS backup makes a stale host tier look
fresh. storage_targets is used rather than pbs_dr.storage_id because the latter
is null on a box with a PBS storage but no DR descriptor.
A tier is only judged when the box HAS it, else every box without an offsite
tier would alarm once the anchor elapsed — R-81's mistake one level down. With
neither tier identifiable (old agent) the pre-Slice-C path runs unchanged.
Intended behaviour change: a 30h offsite snapshot no longer alarms. Three
fixtures asserted the merged threshold; each still asserts an alarm at the
correct limit. No assertion was weakened.
RECORDED LIMITATION: the hub infers 'PBS => weekly' from storage type.
defaultBackupTarget is felhom-pbs, so a box that never sets local_backup_target
would run PBS as its DAILY tier and be judged against 8 days — 7 days of
blindness. No box is in that shape today; the real fix is the agent reporting
per-tier cadences. Own task.
Red-proof observed. Replayed live: demo-felhom OK, demo-hp UNKNOWN (defers
correctly), drill-r50 MISSED (true positive). No customer email would be sent.
