March 2026 (2026-03) Monthly summary for runtimeverification/mir-semantics. Key feature delivered: Efficient SMIR K Definition Pruning via CFG Roots in kmir, enabling pruning of unreachable SMIR K definitions based on a set of CFG roots to speed up SMIR data processing and reduce resource usage. This work is implemented in kmir and committed as 443f9ad229fafbc5431cb543896faf8802c9aa44 (Teach kmir to reduce SMIR K definitions over a set of CFG roots), associated with PR #845 and co-authored by Stevengre and Claude Opus 4.6. Impact: faster analyses, lower memory footprint, and improved scalability for larger CFGs. No major bugs fixed were reported in the provided data for this month. Technologies/skills demonstrated: kmir development, CFG-root based pruning, performance optimization, and collaborative coding with PR governance.

June 2025 monthly summary for Pi-Squared-Inc/evm-semantics focused on CI/CD modernization and infrastructure hygiene to support faster, more reliable releases. Key features delivered: - CI Pipeline Migrated to revm Integration and Cleanup: Replaced the evm-semantics CI workflow with revm-based automation, removed the outdated Dockerfile and release-related CI configurations, and introduced a test-master-pr.yml workflow to verify the pinned revm commit. Commit reference: ad1579d7de36d4f0f1a37d7ce0c9f9afd52b7cb4. Major bugs fixed: - No explicit major bugs logged for this period. The primary work focused on CI/CD modernization and artifact cleanup to reduce maintenance risk and prevent build failures. Overall impact and accomplishments: - Streamlined CI/CD by adopting revm, improving build reliability and feedback time. - Reduced maintenance surface by removing outdated Dockerfile and obsolete release CI configs. - Implemented validation of pinned revm commits via test-master-pr.yml to ensure reproducible builds and safer releases. Technologies/skills demonstrated: - CI/CD pipeline design and migration (GitHub Actions, revm integration) - Build reproducibility and artifact pinning - Codebase hygiene and release process simplification - Commit-based change traceability and traceable impact on the pipeline
