// Strays is what runs on the machine that the mesh neither wrote nor holds (novox/hq ADR 0163):
// every container the runtime has that no record names and no hold names. The question nothing
// answered on 2026-09-23, when a renamed resource left its old container running for a day; asked
// on every apply now, and reported, so a thing left behind is seen the day it is left.
//
// Containers only, today. A listener nobody declared is harder to attribute to a thing, and the
// machine's own services are not strays; that account is issue 160's.
