The gap

When the service restarts or goes down, nothing posts a notice about it. Observed during a load test in which the service came up and down repeatedly: the channel had no message explaining the flapping, only a bot that silently stopped and resumed answering.

Expected

The service itself posts a notice when it goes down and when it comes back up, using the usual notice format, with the down arrow emoji (⬇️) at the start of the down notice and the up arrow emoji (⬆️) at the start of the up notice.

What to decide

Where the notice lands: the lane's own channel, or a status channel.
Lifecycle hooks: presumably around startup and shutdown in the Discord adapter, and whether both notices fire or only one.
Debouncing: a flapping service could flood the channel, so consecutive transitions should probably be throttled.
