May 1, 2026May 2026 monthly summary for gnolang/gno focused on build maintenance, persistence correctness, and test coverage. Key changes delivered: (1) Build System Cleanup: Removed duplicate Makefile targets for calibration and benchmarking, streamlining the build pipeline and reducing CI churn. (2) GetOwnerID Deserialization Fix with Cross-Realm Ownership Tests: Fixed GetOwnerID to return the persisted OwnerID after store restoration to enable correct dirty-walk behavior and prevent stale ancestor hashes; added cross-realm ownership tests to safeguard against regressions. These changes collectively improve data integrity and reliability of object ownership state across restarts. Overall impact: reduced build maintenance overhead, faster and more reliable builds, and stronger persistence correctness with higher test coverage. Technologies/skills demonstrated: Go, Makefile-based build maintenance, persistence/deserialization, test-driven development, cross-realm ownership handling, and clear commit hygiene.
