Provenance

Every lever entry records:

• setBy — who set this position.
• setAt — ISO 8601 timestamp.
• rationale — required free-text reason.

setBy values

Value	Meaning
system-default	The seed value written at workspace init. Edit freely.
spec-agent-intake	Set by the Spec Agent while refining a task in exploring.
user-direct	Set by a human — CLI, dashboard, or hand-edited YAML.
coordinator:<name>	Set mid-project by a coordinator agent acting within its autonomy.

Why it matters

When behavior surprises you, you can trace the exact line in agent-settings.yaml that produced it — and see who and when. This turns "the agents decided to fan out" from an opaque outcome into an explicit decision you can audit, roll back, or argue with.

The dashboard's Settings tab surfaces the setter chip next to every lever, and clicking it opens the full rationale + history.
