 ### Documentation
 - **GFQL component-labeling examples + README clarity (#1324)**: Added concise WCC/SCC labeling examples for `compute_cugraph`, `compute_igraph('clusters')`, and local Cypher `CALL graphistry.cugraph.*` write/row modes in GFQL docs, clarified that component IDs are partition labels (not stable semantic IDs), and tightened the main README GFQL intro sentence for readability.
 
+### Tests
+- **GFQL / Cypher two-MATCH reentry varlen regression hardening (#1001)**: Strengthened reentry varlen acceptance assertions from shape-only checks to exact expected rows, and added forward/reverse split-vs-connected query equivalence regressions to guard against wrong-row drift in the `match5-25/26` query family.
