The fixed scheduler observation an ISchedulerDiagnosticsSource
records (M98k). fire is one local timer fire of an approved job —
observed whether or not the fire proceeded, so contention and lock
failures are visible; attempt is one invocation of the application's
handler by the executor. A behaviour that declines a dispatch (never
calling next(), or throwing) invokes no handler and records no attempt;
the fire still reports the dispatch's settlement.
The vocabulary is fixed — a fire is never described by a schedule kind or
an application string.
