Two agents could start on one issue without seeing each other, and an issue
could be resolved without anyone having said they started its fix. A move to
diagnosing or fixing now names by, the worker as who@node; get and list show
the worker with since and stale; another worker is refused while it is
current unless take-over says why (noted); a worker untouched for
worker-stale-after (24h) may be taken over from without a reason. Resolved is
reached only from fixing. The moved event carries by, since and caller.
Fixing counts as not closed for the triage and the duplicate check.
