Sep 1, 2025September 2025 monthly summary for silvest/HEPfit: Delivered a new capability to load and resume MCMC runs from an input file, enabling continuation of marginalization from a saved state, and updated the MonteCarlo flow to support input-file loading. Completed critical fixes in NPSMEFTd6General and NPSMEFTd6GeneralMatching to improve initialization, matching correctness, and sign conventions, boosting reliability and SMEFT@NLO compatibility. These changes enhance reproducibility, reduce rework for long-running analyses, and improve numerical accuracy across SMEFT workflows.

Jun 1, 2025June 2025 monthly summary for silvest/HEPfit: Delivered key features to support RGE workflow and enhanced observability, fixed critical bugs affecting input handling and parameter updates, and refined initialization flows for SMEFT paths. These efforts improve reliability in SMEFT/RGE analyses, enable clearer debugging, and set the groundwork for MFV SMEFT. Key business outcomes include more accurate event generation in noMC mode, robust SMEFT initialization for the RGE solver, and reduced risk of incorrect parameter propagation due to input handling issues. The work demonstrates strong C++ maintenance, debugging discipline, and thoughtful refactoring to improve clarity and testability across the HEPfit codebase.

Mar 1, 2025March 2025 delivery for silvest/HEPfit focused on stability, performance, and developer experience. Implemented robust error handling in Monte Carlo simulations to prevent crashes when phi2 calculations fail by updating the MonteCarloEngine to treat Standard Model success status when discarding events. Added user-focused documentation and installation improvements, including README updates that specify submodule usage (--recurse-submodules) and links to the GitHub Pages site. Executed a performance-oriented refactor in NPSMEFTd6General.cpp, replacing string-based checks with integer switches for particle identification and refining SMEFT coefficient retrieval pathways across energy scales (with controlled disable/enable sequencing).
