Supervisor
One parent run, scoped child runs.
The parent run owns the shared intent. Child runs own repo-specific implementation and review. Contract checks reason across the boundary.
Cross-project
Cross-project work needs integrated evidence.
The cross-run supervisor coordinates a global plan, per-project runs and a final system gate. Each project keeps local evidence while the parent run preserves the cross-system contract.
TECHNICAL PROOF Route status
cross_project_handoff / spec-19f cross-project
api producer fixed
web contract guarded
mcp proof surface
review gate linked
Final gate
Acceptance happens at system level.
cross_final_acceptance can reject if one child gate failed or if the integrated proof is missing, even when local diffs look correct.
