Rebuild route-derived edges during incremental indexing and clear only derived HANDLES/DATA_FLOWS rows that are owned by the route reconciliation pass.
Make infra route matching order-independent by considering every matching handler route, and make prefix-route bridging inspect every registrar edge while keeping diagnostics on the existing logger.
Reuse the full-index file/folder structure helper for changed files so incremental updates restore File metadata and CONTAINS_FILE/CONTAINS_FOLDER edges consistently.
Add graph-buffer selective edge deletion and regression coverage for route matching, prefix bridging, and full-vs-incremental edge accuracy.
Tests: build/c/codebase-memory-mcp; CBM_ONLY_SUITE=graph_buffer build/c/test-runner; CBM_ONLY_SUITE=infrascan build/c/test-runner; CBM_ONLY_SUITE=pipeline build/c/test-runner; CBM_ONLY_SUITE=incremental build/c/test-runner; CBM_WORKERS=1 CBM_ONLY_SUITE=incremental build/c/test-runner.
Caveat: incremental remains below the >=10x speedup gate for default enablement; full rebuild remains the safe default until the delta design is redesigned and measured.
