Overnight soak on demo-hp, phases 0-4 of 7. Evidence documentation/audits/DRILL-soak-2026-08-31/. No production code written, no golden, no version bump - findings only. PHASE 1 FAIL - R-411. The R-408 hazard was only ever reasoned about; tonight it was measured through the product's own endpoints. restic stats TAKES A LOCK (clean-room: nothing else running, 4x stats, sampler reads locks=1). A customer full-restore runs stats in its preparation while holding NO acquireRunning, so the integrity check is not blocked, runs, meets that lock, and resticStep escalates to unlock --remove-all - the sampler caught "restore ..." and "unlock --remove-all" in the SAME sample at 20:50:51. The log calls it "a stale exclusive lock left by a previous crash"; there was no crash. THE CUSTOMER-FACING CONSEQUENCE IS CONTAINED and that is R-359 working: the check was classified Unreachable, NOT damage, so no alarm and due-ness held. The opposite direction is FENCED - five restores fired into a running check at 5/15/25/35/40s were all refused by restoreOpBlocked with zero restic invoked. PHASE 2 FAIL - R-412, and it is the natural instance of R-403's shape that yesterday's session had to hand-build. A lost primary unit is rebuilt by the capture WITHOUT its volume dumps (185664 B -> 4382 B, volume_dumps: None), and the off-site backup then ships it and logs "backed up opengist ... 0 mandatory path(s)" - a success line over a backup holding none of the app's data. PHASE 2 also R-413: the R-87 proof CAUGHT that hollow snapshot unattended - verdict "fail", volumes_expected_none_captured: opengist_data, one offsite_proof_empty at severity error, while the four apps ahead of it in the rotation passed. 2.3 stale marker PASS, 2.4 two restores PASS, 2.5 corrected the runbook's premise (RunTier2 has zero acquireRunning and zero restic references - a local mirror cannot collide with the repo, so the proof correctly does not skip for it). PHASE 3 PASS - R-357 live-validated at last, six days owed. A real full filesystem (1900544 B free vs 5878421 B needed) on a separate 1 TB device that does not back Docker. Refused BEFORE StopStack: app "Up 6 minutes (healthy)" unchanged, 0 safety dumps, live userdata tree fingerprint 5a9b2db75dfd4ba4131adb3255670472 unchanged, message names both numbers in Hungarian. Ballast removed, the SAME restore then worked and the fingerprint is still identical. On the same full disk the Tier-2 run, the proof and the integrity check all behaved: the proof refused before any download through the shared unitOnlyHeadroom gate extracted today, reached no verdict and did not alarm. PHASE 4 PASS - the false-alarm control the whole R-87 design rests on now EXISTS. Found by reading all 53 catalogue composes: bentopdf is the only template with neither a database service nor a named volume. Deployed, backed up, proved: PASSED in 2.224s with zero alarms. Four of my own instrument errors were caught by their own controls before any result was believed: a hub log line used as a controller positive control, a grep pattern that missed a registered job, a heredoc that mangled a planted marker, and a catalogue scan that read 0 of 0 apps from the wrong path. Phases 5-7 to follow: the real nightly cycle with injected faults, the untouched observer, and teardown.
documentation/backlog/
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.
