What a schedule's row keeps of its last run: the moment the firing that started it came due, one of four outcomes, the runner's own message, and how long the run took. Nothing before it — there is no run history, and a skipped firing leaves no trace — because the node is a script runner, not a reliable scheduler. What a script produces goes where the script puts it; anything it wants kept beyond one line, it writes to the notebook.
The outcome answers "did it work, and whose move is it" in one word, grouping
the reasons YmerNode.Scripts.Runner tabulates:
| outcome | reasons | whose move |
|---|---|---|
ok | — | nobody's |
refused | :not_found, :not_accepted, :not_loaded, :unknown_action, :invalid_schema, :invalid_args | the run never started: fix the schedule, or accept the script |
error | :script_error, :script_raised, :script_exited, :bad_return, :result_not_encodable | the script ran and failed: fix the script |
timeout | :timeout | the run passed its deadline and was killed |
:not_found is the one reason that is not the runner's: the script's row gone
between a firing and its run. A script's schedules are deleted with it, so only
that window can see it.
The message is the runner's rendered text, cut short at a fixed length: it is a line to read in a listing, not a log.
