PASS production-source public verify_artifact admission of all eight measured outputs, including canonical expanded module hash checks.
Local output: build/reports/root-ranges-706/native-verify.txt
PASS python3 docs/benchmarks/root-ranges-706-2026-10-07/verify_legacy_equivalence.py
All eight range outputs reconstruct exact #704 SHA-256, then exact original pre-path-pooling SHA-256.
PASS analyzer: hashes and byte totals reconcile for eight files; logical empty-root, root-set and repeated-map counts equal the #704 inventory.
PASS negative reader check: strip nonsemantic debug sections from compact boot, rebuild canonical directory and SHA-256, isolating the new root-range marker.
Updated native reader accepts; frozen baseline reader rejects with BadSection, "unknown required or semantic section", before execution.

Scope: artifact encoding/decoding, module hashing, bounded expansion, focused native/JVM execution and small-heap GC/quota coverage.
No interpreter timing improvement, full-checkout verification, GameTests, cross-platform bundle coverage or release readiness claimed.
Published Runtime 0.20.0 bundles lack both compact markers; updated source-built natives required. Native release and parent pin update remain separate.
