Oct 1, 2025October 2025 performance summary for SCM-NV/PLAMS: Delivered a critical reliability improvement in the geometry module by addressing a MyPy type checking issue. The fix added an extra type ignore on the vector normalization line to suppress a spurious type error. This reduces false positives in static analysis, keeps CI green, and lowers maintenance burden for future geometry-related work. The work enhances developer productivity, enables smoother feature delivery, and preserves type safety in core math routines.

Jun 1, 2025June 2025 focused on delivering robust PackMol improvements in SCM-NV/PLAMS, expanding test coverage, and modernizing the build and docs. Key features delivered include core enhancements for density-based n_molecule estimation and stricter box_bounds/n_molecules validation (including support for one None value), extended molecular volume and density estimation for metals via a new _guess_molecular_volume helper, and a suite of comprehensive unit tests that robustly handle floating-point inputs and invalid structures. Additional work covered documentation updates (NaCl solution section and compatibility notes) and practical examples; API/utility rename cleanup (run_directory -> jobs_in_directory) to improve clarity; and a migration of the build system to hatchling with updated pyproject.toml, removing legacy setup.py and tightening CI/coverage thresholds. Overall impact: higher accuracy and reliability for PackMol placements, broader metal support, stronger test guarantees, clearer APIs, and faster CI feedback, enabling scalable simulations and easier collaboration.

Dec 1, 2024December 2024 (SCM-NV/PLAMS): Delivered key features, fixed critical issues, and improved observability and maintainability. Enhanced logging in the Job Manager and runtime (end-of-job logs, robust handling of invalid logfile paths, status checks before logging) which reduces noise and accelerates issue diagnosis. Refactored core architecture by converting the Job class to an abstract base class (abc) and introducing a fail-on-exception decorator to improve resilience. Improved error messaging with base-level error retrieval and fallback to error files, including license error handling and tests for multiline error logging. Added job status logging to the job logger CSV for better traceability. Improved release hygiene, typing quality, and test infrastructure, laying groundwork for more scalable, reliable job processing.
