Sep 1, 2025September 2025 monthly summary for sufst/pcb: Implemented automated CI improvements to strengthen PCB design validation and release packaging. Added GitHub Actions workflows to automatically validate KiCad designs via DRC/ERC checks on pull requests and to generate release files based on PR activity. Included automation to propose release file generation when PRs are opened or updated, enabling faster, more reliable artifact readiness. The work builds on the accu-bms-interface integration, consolidating validation and release preparation into a single end-to-end pipeline. Business impact includes reduced manual validation effort, earlier detection of design issues, consistent release artifacts, and improved traceability for compliance and customer delivery. Technologies/skills demonstrated include GitHub Actions, CI/CD automation, KiCad DRC/ERC validation, PR-driven release automation, and automated release artifact generation.

Feb 1, 2025February 2025: Implemented repository hygiene improvement by updating .gitignore to exclude KiCAD/EDA transient lock files (.lck). This prevents these files from being tracked, reducing noisy diffs, and avoiding accidental commits of build artifacts. The change improves CI stability and maintains a clean project history. Commit reference: f8f5633b03499d5f53f0b84c6364b5e86c527133.
