What problem does it solve? When multiple isolated feature lanes finish implementation, teams lack a structured way to verify readiness, detect merge conflicts or shared-surface overlap, and close lanes cleanly before merging to mainline. ## Core Features & Use Cases - Lane Discovery and Prechecks: Discovers completed feature lanes and runs integration readiness checks against verification evidence. - Drift and Overlap Detection: Surfaces shared-surface overlap, merge sequencing risk, and unresolved blockers instead of hiding them behind a generic done status. - Integrated UI Evidence: For UI-bearing lanes, recaptures viewport and state evidence against the integrated tree before allowing closeout. - Use Case: After three parallel feature branches complete implementation, run this workflow to confirm each lane's readiness, get explicit closeout guidance, and sequence the merges safely. ## Quick Start Ask the agent to run sp-integrate to check integration readiness and close out the completed feature lanes before merging to mainline.
