The health monitor lets a pending-restart continuation skip the cooldown so a
timed-out recovery stop can finish on the next pass. That continuation was
never recorded, so an account stuck in restartPending with reconnectAttempts 0
restarted on every check forever, bypassing maxRestartsPerHour entirely: stop
and start thrash the channel manager with log spam and no give-up state.
Only the first continuation per pending episode is now free. Later passes
rejoin cooldown and the hourly budget, and the free pass re-arms only after
the account genuinely leaves restartPending (running again or the pending flag
dropped) so a transient reconnectAttempts bump cannot mint new free restarts.
