🔧Conformance levelPartial (measured) — hardening under I-INIT-GQLC

What this means#

ArcFlow passes 2,192 of 3,881 openCypher TCK scenarios at strict canonical equivalence (~56%, release 2024.3, measured 2026-06-29). Remaining scenarios fail on result values (~16%), error type/code (~11%), result shape (~8%), error phase (~7.5%), and ordering (~0.6%). Conformance hardening is in active progress under I-INIT-GQLC. The TCK is the industry-standard cross-vendor compatibility surface for Cypher.

🧪 Reproducing#

The full per-scenario result set is too large to vendor in this repo (one JSON per scenario, 3881 files). To reproduce, run the conformance harness against your installed engine binary.
