R-216: the offsite key recovery is a coupled feature and now says so. featureProbes +
featureMinAgent 0.125.0 + a Supports gate at the unlock entry point, FAILING CLOSED — an
agent that cannot answer is named as such instead of the customer's code being blamed.
Measured live: a 404 from agent 0.120.0 came back as "we did not accept your recovery
code, check that all ten words", in 0.134 s, against a perfect code.
R-218: delete the repo-password short-circuit in needsOffsiteCredential. The declaration
stops when the TIER WORKS, not when a key exists — installing a key is the recovery
screen's whole job, so succeeding at recovery was switching off the mechanism that would
have delivered the coordinates to use it.
R-219: the unlock finishes the job — place the key, bring the tier up, then list. Without
it the promised listing could never render on the shape the screen exists for.
R-217: an unreadable store no longer claims to have opened with unattributable content
(the OffsiteInventory{} zero value). Opened / empty / unreadable are three states.
R-222: a code that is right about a RETAINED earlier package is named, not blamed. States
what the hub knows and promises nothing — no read path exists.
R-215: GET /recovery is gated on the same predicate as the interception.
Five red-proofs, each demonstrated failing and restored.
An absent off-site object has four meanings — never configured, mid-restart, a
transient config read failure, and rebuilt-and-stranded — and the hub cannot tell
them apart. The box can, from two local facts it holds with certainty, so it says
so instead of leaving the hub to deduce it from a silence (operator ruling).
The ACK's identity_blob_present is now recorded on EVERY ACK, before the gates
that used to discard it: on a box with no off-site target the auto-confirm returns
immediately, which is exactly a rebuilt box, so the one fact distinguishing it from
a box that never had off-site backups was thrown away every cycle.
The declaration needs BOTH halves — a fresh data area AND a hub-held recovery
package. Freshness alone is a box that never had off-site backups; dropping that
condition makes the whole fleet ask for credentials, which is what the Scenario B
test exists to catch.
The object carries enabled:false and zero sizes, which is what makes it inert to
the hub's existing fill and staleness checkers and to a pre-upgrade hub. A
configured box's JSON is byte-identical to v0.198.0's.
