The vault's seat, and a report that carries the machine's profile (hq ADR 0161)

mesh-vault joins the mesh's own set — mesh-scoped, delivering secret — because the controller seals
every minted credential with it, which is the test for a seat of the mesh's own; a second provider is
a second claimant, refused by name (issue 106). A report may carry the machine's profile, detected
again by the apply that reports, and the latest replaces the enrolled one: a machine that switched
its network manager is a machine whose uplink holder lacks a capability at its next push (issue 138).
