Two files with two values, two holders in the vault's ledger — the identity with the
local name after it — and one rotate moves both (novox/hq ADR 0094).
The vault bed grows into a create-once file and pushes again; the genesis bed
probes the machine from the workstation for the whole install and asserts the
store's port never answers while the bus's does.
Design 13's three logins, for a secret that had no owner before (novox/hq
ADR 0085): the delivered password authenticates against the real redis, the
one `rotate secret` delivers authenticates, and the one rotated away is
refused. Plus the owner's half: the vault's ledger names the holder and the
fingerprint, notices the rotation, and answers over the mesh by fingerprint,
never by value. Runs the catalogue's own manifests.
