April 2026: Delivered MQOM algorithm integration into liboqs, expanding cryptographic agility with multiple parameter sets and architecture-specific optimizations. Implemented MQOM import with memopt variant, refactored common MQOM code for maintainability, and updated tests to validate coverage. Documentation and build configurations were updated to ease adoption and downstream integration (including new readme entries related to copy_from_upstream). Minor maintenance included removing an incorrect debug print in copy_from_upstream and adding a readme for upstream processes. Overall impact: stronger PQC capabilities for downstream projects, improved performance on targeted architectures, and enhanced build/test readiness with clearer guidance for production deployment. Technologies/skills demonstrated: C/C++, cross-architecture optimization, build system updates, documentation, and extended testing with collaboration across contributors.

Concise monthly summary for 2025-01 focused on feature delivery, bug fixes, and overall impact in the Cairo repository. The month centered on documenting gas accounting to improve clarity, onboarding, and maintenance of the gas accounting model, with direct traceability to a committed change.
