-# Execution Layer — Plans
+# GraphWeave — Plans
 
-Plans for the GraphWeave execution layer (FastAPI + LangGraph backend).
+Plans for the GraphWeave project, organized by layer.
 
 Each plan is written before implementation, reviewed, and committed.
 Implementation deviations are logged at the bottom of each plan file.
