May 2025 monthly summary for rems-project/cn: Delivered configurable C compiler support to enhance build flexibility and CI integration. Implemented an optional --cc argument in frontend and setup modules to select the C compiler, with a fallback to the CC environment variable or the default 'cc'. CN-exec updated to apply a user-provided C compiler path for compilation commands, enabling teams to customize their toolchains.

Concise monthly summary for 2025-04 focused on delivering modularization, refactoring for clarity, and reliability improvements in GaloisInc/cerberus, with a clear link to business value and technical progress.

Monthly summary for 2025-03: Delivered a set of focused engineering improvements across two repositories, emphasizing modular packaging, memory correctness, and CI efficiency. Key outcomes include: (1) Cerberus runtime packaging and build system refactor in rems-project/cn: extracted cerberus-lib from backend packages, updated build configurations and CI tests, and migrated runtime references from CERB_RUNTIME to CERB_INSTALL_PATH; (2) Memory size calculation fix for C structs with a flexible array member: corrected offsets and sizeof handling to account for trailing padding, ensuring accurate memory layout; (3) Coq pretty-printer module qualification fix: added missing Mem qualifiers to Coq constructors in impl_mem.ml for clearer and correct generated code; (4) Discontinued cn CI workflows in GaloisInc/cerberus: removed CI workflow files for cn component, reducing maintenance burden and CI resource usage. Overall impact: improved build stability and modular packaging, more accurate memory modeling and Coq code generation, plus significant CI cost reductions. Technologies/skills demonstrated: OCaml/Dune-based build system refactor, C memory layout calculations, Coq code generation and qualification, and CI/CD workflow management and cleanup.

February 2025 monthly summary for rems-project/cn focusing on delivering foundational scaffolding for formal verification with Coq, cross-backend runtime clarity, and dependency stability. Key activities include introducing Coq integration scaffolding in the Symbolic module and aligning runtime namespace usage across backends, complemented by dependency constraint updates to improve build reliability.
