Roadmap to GEMC 0.4

New features, improvements, and issue resolutions planned for the next release.

Included are the milestones for pygemc and clas12-systems.

Highlights include the post-digitization threshold and efficiency policy API in GEMC core: plugins can cache deterministic transient GDigitizedData values, apply detector-intrinsic policies after digitization, and keep efficiency random draws inside apply_efficiency_impl. The CLAS12 DC, ECAL/PCAL, and FTOF plugins use this split so digitize_hit.cc builds detector observables while dedicated apply_thresholds.cc / apply_efficiency.cc files own the policy decisions.
