DRILL: the retained key works, and the customer cannot reach it

Three verdicts, kept separate because collapsing them is how this assumption
survived a week.

(a) The material IS retained. host_escrow_superseded id 11 is the first retained
row in fleet history to carry identity_blob (572 B), byte-identical to the
pre-supersession row (sha256 a10032341c8584ed...).

(b) The retained material DOES open the old store. Unsealed with the old recovery
code it yielded a password byte-identical to the pre-change one, and restored
three planted files byte-identical from a store the box itself could no longer
open - including a Hungarian accented filename verified as raw bytes. Negative
control ran first and failed closed.

(c) The customer has NO route, and is misinformed. ListSupersededEscrow has zero
production callers; the recovery path selects FROM host_escrow. Asked with the
code that had just worked by hand, the product answered "the recovery code did
not open the sealed bundle". A valid code for retained history is reported as a
bad code - the R-224 class again. R-304, rank 1.

Both installer faults were watched happening first, so installer-v1.27.0 is now
published (tag + both webpage.yaml refs). Pre-fix: the box came up on controller
0.98.3 against a vouched 0.213.0, below the floor and below the version carrying
the recovery screen; and our own uninstall left dnsmasq on 0.0.0.0:53 so our own
next install refused. R-297 and R-300 CLOSED.

Also filed R-305 (the dnsmasq fix fires once per machine - the leftover returns
on the second reinstall, proven), R-306 (--preflight-only writes state it says it
does not), R-307 (a live abandon countdown on demo-felhom, firing 2026-08-24 -
operator decision), R-308 (stored controller password stale), R-309 (the day-0
runbook's publication claim has been false since R-110), R-310 (two edges).

Ceiling R-303 -> R-310. Capability map moved: the retention claim is now marked
operator-only. Phase A logs did not survive the intermediate revert; recorded.
