A failure that repeats is said to be stuck

The mesh kept one report per machine, replaced, so a resource nothing can ever apply
looked like a failure that had just happened, every reconcile interval, for ever.
The row now keeps when the current failure began and how many reports in a row have
said it — the same outcome, refusal and failed resources; anything different starts
again and a clean apply clears it. Three make the machine stuck, and status says so
beside the failure, in words and in JSON (novox/hq 04-ISSUES/065, ADR 0090).
