A take is a comparison: the preview, its refusals, the strays, and the policy said at build (hq ADR 0163)

The host now reports, for every held thing, the facts a take compares; the controller keeps them, and
take puts them beside what the module declares — the found image and its age against the declared one,
the found networks and who else is on them, ports and mounts, a found file's difference from the
declared content — and refuses a downgrade without --downgrade and a differing file without --replace
<path>. Without --yes the comparison is printed and nothing is taken. node show lists the facts and
the strays the machine reports. build and the daemon's take-in say when a module's policy rolls the
result out at once. The own-secret refusal points at the provider form for a required secret.
