• CLAS12 HTCC example added (page, gallery card, assets)
• C++20 / ROOT branch-lookup fixes across Meson and CI
• New GEMC detector-construction and PyVista CI tests
• Geant4 collaboration meeting (full week)

GEMC

• Added the CLAS12 HTCC example page and gallery card; regenerated its screenshot, VTK, and analyzer assets.

Geant4

• Attended the collaboration meeting all week (days 1–4).
• From day 1: working through user requirements; keeping up the dailies — checking the user forum and open bugs.

GEMC3

• Released GEMC 0.5, pygemc 0.5.0, and CLAS12 systems 0.3, and updated the released documentation.
• Prepared the upcoming release notes for GEMC 0.6, pygemc 0.6.0, and CLAS12 systems 0.4.
• Added the GEMC 0.6 news roadmap with core and CLAS12 milestones, issue lists, and progress indicators.
• Migrated the GEMC, pygemc, and CLAS12 nightly workflows to DRelease v1 with automatic tag-date notes.
• C++20 / ROOT work:
  • Restored C++20 ROOT branch lookups after filtering dependency standard flags, and verified compilation.
  • Kept Meson’s C++20 setting authoritative over ROOT flags; verified dependency-standard overrides.
  • Fixed ROOT branch-lookup compatibility and verified compilation under both C++17 and C++20.
  • Fixed a malformed dependency header that was blocking sanitizer CI, and verified all wraps with Meson.
• CI / build:
  • Added backward-compatible pygemc source discovery for GEMC CI; verified legacy and shared installs.
  • Fixed the GEMC subproject Python install to use the resolved pygemc source; verified shared checkouts.
  • Standardized CLAS12 container workflows on Geant4-only images; verified source-build setup and matrices.
  • Updated macOS CI to build GEMC as a subproject and to diagnose missing Geant4 release archives.
  • Fixed macOS CI library lookup for an installed GEMC; reproduced the CLHEP loader failure and recovery.
  • Fixed macOS CI archive selection to match the configured Geant4 and runner compiler versions.
• Testing:
  • Added OpenGL dependencies and native-filter checks to PyVista CI; verified the full Python test suite.
  • Restored curved-solid PyVista previews, corrected VTK sphere intersections, and verified all HTCC mirrors.
  • Added seven GEMC detector-construction tests with CAD and plugin loading; verified both SRO tests.

Actions

• Built a reusable nightly release action (DRelease) with automatic tag dates, configurable notes, and offline tests.
• Aligned DRelease with the shared Node action, CLI, workflow, and test conventions of the profiling projects.
• Added initial DRelease release notes following the Callgrinder format and updated the action usage docs.
• Documented how to update pull and merge requests from forks — using the existing source branch and remote, handling rewritten commits, plus browser editing and review-suggestion instructions.

Homepage

• Documented connecting an existing directory to a remote Git repository while preserving local files.
