Every check the mesh had was right about the world it was given and none was given the mesh's: a real machine's name made an identity too long (263), the node-engine refused what the catalogue check passed (236). The controller now composes what a check needs - every machine under a pseudonym of its name's length, its roles, system, builds, capabilities, assignments, pins, settings and how its declaration composes; every seat, module and source; the bus, store and node-engine versions it runs - with no secret, no address and no name, and keeps it in the artifact store as facts:latest when it moved, or daily. The replaced snapshot's manifest is let go of, so the nightly collector takes it. S14 raises facts-stale past two days.
