(Commit: 4757c2fbd9763558b3fa56e20223eb5bffcdaad8) Major achievements reflect an emphasis on delivering business value through accurate numerical methods, measurable performance tooling, safer geometry handling, and enhanced API capabilities for complex simulations. Top 3-5 achievements: - Numerical integration enhancements (Simpson with trapezoidal extension; user-defined uniform points; corrected coefficients) - Profiling-ready build scaffolding (kokkos regions, cmake options) - Crank-Nicolson timestepper for multipatch objects - Collision geometry cleanup and validation (assertions; removal of 5D geometry) - MultipatchBuilder API extension (BcTransition in template args)
