# section: when a step returns `StepResult(status=StepStatus.FAILED, ...)` and
# `continue_on_error: true` is declared, the engine records the step's
# `output` (with `exit_code` and `stderr` from the failure) and its
# `status` (sibling key on `steps.<id>`, not nested under `output`)
# and continues to the next sibling step instead of halting the run.
# Gate aborts (`output.aborted`) still halt regardless of the flag.
# Unhandled exceptions raised out of `step_impl.execute()` are out of
# scope for this flag — they propagate to `WorkflowEngine.execute()`
