Third instance of one class (hub v0.12.0, v0.73.0, this), fixed as a class. On 2026-07-26 03:00 UTC expected_backup_missed fired on demo-felhom, demo-hp and drill-r50 at once; the demo-felhom one reached the CUSTOMER channel claiming "newest backup is 176h0m0s old". Nothing was wrong — three vzdump archives were on disk. Cause: the agent backup store is in-memory, so the R-50 fleet restart emptied `backups` until the next run, and the hub read empty as "no backup exists". - assessBackupFreshness returns OK/UNKNOWN/MISSED instead of `missed bool`; absence is UNKNOWN until it outlives an anchored window. Still pure. - store.GetHostReportsSince + monitor.newestBackupEvidence read the hubs own retained history (bounded 7-day lookback, early-exit on fresh evidence) — "when did I last SEE evidence of a backup?" The anchor was free: the hub already retains 90 days. No agent change, no new persisted state. - store.GetFirstHostReportAt anchors absence at first contact, reusing the existing 26h threshold as the grace (no new knob, the v0.73.0 shape). - Deferrals logged + counted; reason strings kept distinct. - backupStaleAfter untouched; landmine recorded (a weekly PBS snapshot would alarm six days in seven) and owned by R-82. Tests 493->508. Red-proofs A/B/C observed and restored; A reproduces the live message verbatim. Replayed the real 03:00 reports (600/417/77 rows): all three now silent.

Verified-LIVE findings with implementable fix plans that are not yet implemented. Preserved here
(instead of on git branches) per the trunk-based, no-branches rule — the fix itself is implemented later
directly on main, during a normal/supervised session.
-
FIX-M18-NOTES.md — dump re-validation runs every 5 min (perf). FIXED in controller v0.62.0 @
f8afe5c(2026-06-14). (was on the deletedfelhom-controllerbranchfix/m18-dump-validation-cache.) -
FIX-M19-NOTES.md —
deriveStackNamemisattribution edge (low-incidence correctness). FIXED in controller v0.62.0 @6bab68b(2026-06-14). (was on the deleted branchfix/m19-stackname-crossref.) -
FOLLOWUP-golden-default-controller-tag.md — the golden bakes a stale controller (
:0.43.0when queued; had rotted again to:0.85.1by resolution). FIXED in felhom-agent @ceca355(2026-07-03):build-golden.shv2.0.0 makes the controller tag a MANDATORY argument (a required arg cannot rot) and golden 0.98.3 was baked + clean-room-validated (bake → first-boot-current → self-manage → app deploy, on the drill VM — no supervised touch of live guests needed) + published + vouched. Evidence:../audits/DRILL-golden-098-2026-07-03.md.
Related: the live-drive fixspec (../audits/live-drive-fixspec-2026-06-14.md) carries the deferred
supervised items F9 (HDD provisioning/guest-attach), F20-BUG2 (durable_id scheme), F20-BUG3 (async
mkfs) — to be implemented in the agent/golden supervised session.
