The absent-state /disks payload was captured on a genuine device loss, after a present-drive control run proved the query works (Part 5's three attempts failed on token extraction, and its control returned 0 rows). The answer is theory #1 -- "the registry-union row writes false" -- which was raised, declared wrong and retracted. The retraction was the error. Absent state returns 4 rows, not 3. The drive appears twice and the two facts the controller needs sit on different rows: the Observe row has backup_target:true but mount_path:"" and guest_path:"", so it contributes no key to driveTargetByPath; the registry-union row owns /mnt/felhom-drives/<name> and omits BackupTarget from its struct literal (disks.go:301-306) => false. The union row is not deduped because seen is keyed on MountPath (:290-295), the one field the absent state empties, and its own MountPath comes from the systemd .mount unit FILE (registry_known.go:40-75), which never reads the mount table. Theory #2 (the basis of the shipped v0.115.0) is false on both halves; #3 is false too. v0.115.0 is provably inert: StablePathForRaw("") returns "". Also files the read path verbatim -- the token plaintext lives only in bootstrap.json on the Proxmox host; the agent's store keeps hashes only. New: R-117 (READY M, outranks R-116) -- a returned drive's guest bind is a DEAD mount (EIO both ways) while /disks reports attached + bound_under_parent:true, so the gate restarts the customer's apps onto it and reports healthy with no alarm. R-118 (READY XS) -- an absent drive's union row advertises the root filesystem's capacity as its own. Docs only. No code written, nothing built or published; v0.115.0 untouched. Both demo boxes read-only; drill fixture restored to virgin.

OPEN-ITEMS.md is the register of open work and the file to read first — it holds only what is
open, one row per item, every row with a state and an owner. ROADMAP.md is the full history and
reasoning behind the R-n IDs, including shipped and killed items; an ID is minted there, and a new
instance of an existing item attaches to that ID rather than getting its own.
The rest of this folder: 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.
