#!/usr/bin/env python3 """ CP-27 & CP-28: Call Graph Migration Verification Script (ADR-151 Phase 4)
Verifies that call_graph_functions and call_graph_edges from sessions.db have been properly migrated to kg_nodes and kg_edges in org.db.
This script:
- Compares counts between source and target tables
- Verifies node_id mappings
- Reports any missing functions or edges
- Generates migration status report
