Part 0 — c11 and rewalk destroyed, three layers each plus the off-site side and
the WireGuard peer, via the hub's own cascade (external teardown FIRST, DB purge
LAST). 37.3 GB reclaimed on c11-scratch, matching the 20G+17G measured. Positive
control after each: part4 must still be found, and was. ep0 namespaces now exactly
demo-felhom, demo-hp, part4.
The cascade refuses to delete a live host and there is no decommission endpoint,
so both boxes were stopped and aged past the hub's 30m stale_threshold first.
Register corrections — the durable record was wrong about two shipped fixes:
R-218 REOPENED -> CLOSED. Shipped controller v0.203.0, proven live on a
genuinely rebuilt box: the hub re-staged at 13:24:57Z and the box
collected it on a tick, no guest command line, no operator action.
R-220 "OPEN — NOT FIXED" -> CLOSED. Shipped agent v0.127.0, proven live after a
real guest purge with both raw mounts still on the surviving host:
/disks/candidates returned both drives (before: two empty lists) and both
re-attached through the customer endpoint.
R-236 WITHDRAWN — I FILED THIS WRONGLY. The hub log shows offsiteheal re-staged
the stored secret at 13:24:57Z after its documented two-report debounce, with no
provider credential minted. My Re-issue at 13:26:39Z came 102s LATER, was
redundant, and minted an unnecessary provider credential (subaccount 284735) —
the very double-issue the offsite-delivery guard warns about once a minute in the
log. "Nincs teendod" is true; I did not wait ~16 minutes. Operational lesson, not
a product defect.
R-238 reclassified as a harness artifact (mode=full without confirm=1 is step 1 of
a deliberate two-step and starts no job by design); its real residue — the total
silence of that step — is fixed in controller v0.204.0.
R-237 CLOSED by controller v0.204.0.

Teardown ledger — the campaign venues (2026-08-06)
Three throwaway appliances had accumulated, each with its own storage sub-account, hub record, tunnel
peer and off-site repository. Two were destroyed here. The third (part4, VM 323) was kept until
Parts 1 and 3 had banked their findings, and goes separately.
What was matched, and how
Matched on identity — customer id → host id → off-site sub-account → wg peer — never on size. The
hub's own delete-preview (GET /configs/<id>/delete) was used as an independent enumeration and
agreed with the hand-built one in every field.
The cascade is the hub's, not a hand-deletion
POST /configs/<id>/delete runs the designed teardown: leg 1 hosts (including
DELETE FROM wg_peers WHERE host_id = ?), leg 2 the committed reset with external teardown FIRST
(off-site store + PBS namespace destroyed), leg 3 residue, leg 4 the customer record and all escrow
ciphertext. Its own confirmation: „offsite tároló és PBS névtér megsemmisítve… Visszafordíthatatlan."
Six gates, all of which had to be satisfied deliberately — three acknowledgements
(ack_hosts/ack_reset/ack_purge), a type-to-confirm confirm_id, an expect_hosts race guard,
and — the one that shaped the whole operation — the cascade refuses to delete a live host:
Delete refused: host c11-36d660 is ONLINE. Decommission the box first — the cascade never deletes a live host.
There is no hub decommission endpoint; the word appears only in that refusal. So both VMs were
stopped and the hub was allowed to age them past its stale_threshold (30m, from the deployed
hub-config) before the cascade would accept them. rewalk aged out at ~21 min of silence, c11 at
~28 min — the two boxes' last reports had landed at different points in their cycles.

Space returned, measured
c11-scratch used: 58,578,256 KiB → 21,228,640 KiB = 37.3 GB reclaimed, against 20 G + 17 G
measured before deletion. Free went 874.8 GB → 912.1 GB.
The positive control
An absence proves nothing unless the instrument can still find something. After each cascade the same
greps were run for part4, which must survive: host part4-905bdb still present (2 rows), wg peer
10.77.0.7 still present, ep0 namespace part4 still present. So the zero counts above are
measurements, not a broken query.
ep0 namespaces after both teardowns: demo-felhom, demo-hp, part4 — exactly the three that
should remain. Nothing on ep0 outside the campaign's own namespaces was touched.
Untouched, as scoped
demo-hp itself and its guest 9201, demo-felhom, drill-r50 (VM 300), DooPlex, the tester's box,
and every ep0 namespace that is not the campaign's own.
