The operator stopped believing the mesh's notifications: one problem stood
twice on the desk (a reminder beside the message it followed, an escalation
then a reminder 31 s later), a unit failing again at each apply was said
again 22 times, and a question's buttons outlived it on a reminder the
ask's end never reached.
- messenger: a reminder or escalation is said in place of the problem's
message (Replace under its handle), alone, never as a digest line; a
problem first said in a digest gets its own message next time. A
reminder counts from when it was last said. A clearing is said once it
stays cleared 2 min (10 min once it came back); back before that, the
message continues without a word. Cleared before ever said and back:
said. An ask's expiry is said with its day.
- desk-channel: a send or show under a handle already shown replaces its
notification by the notifier's replace id.
- telegram: the same deletes the earlier message and sends the new one,
ringing as its kind rings; one it cannot delete loses its buttons.
