Run statuses
Workflow runs use the same state machine as pipelines:
The app loads allowed actions from /pipelines/status-machine (e.g. Start, Resume, Cancel, Rerun, Archive).
Recovery actions
Clone and Rerun need a live Bridge connection — the API returns 503 if no agent runtime is connected.
Blocked runs
When a step task is blocked, fix agent credentials or instructions on the task detail page, then Retry or move to backlog per task rules. Pipeline-level Resume may be available depending on status.
Definitions with zero nodes
You can save an empty workflow definition (zero nodes) as a draft placeholder — useful while designing, but activation requires at least one valid step.
