Sub-Agent & Work Lineage Graph
Direct parent-child session counts from recorded rows v_subagent_lineage; depth, cycle, and unresolved-parent verdicts come from canonical insight I09 (missing parents remain unresolved and are never imputed as roots).
All-time counts — window_from/window_to label the snapshot but do not filter.
Children Traced Under Each Parent Session: Amber bars illustrate the volume of delegated child sessions grouped by parent caller:
spawn
Direct child subagent instantiation where a parent session spins up an ephemeral or worker session.
delegate
Work handoff to an existing colleague seat or specialized agent without creating a new root.
handoff & return
Queue step transfer and subsequent child completion report returned to the supervising parent.
Root Invariant
Missing parent sessions remain explicitly categorized as 'unresolved' and are never imputed as artificial global roots.

spawn
A caller starts a child session. The child counts toward that parent. Missing parents remain unresolved and are never imputed as roots.
delegate
Work is handed to another session without treating the delegate as a new root.
handoff
A recorded transfer along the lineage. Queue handoff friction across actors is tracked on the handoff view.
return
The child reports back. A return is an edge status or relation, not a rework rate.
