# Builds the PC 1 AMD kit for the Counter ASIC 3.0 jobs in this folder (6 October 2026): the OpenCL worker from
# THIS tree's proto-opencl/host.c (the installed worker's source plus the `build <ms> clBuildProgram` line), the
# OpenCL family probe (proto-opencl/family-probe.c), both cross-compiled with mingw exactly as
# proto-cuda/nvrtc/build-windows.sh builds the shipped worker (static, IGNEUM_CL_DYNAMIC, OpenCL.dll at run time;
# no icon or version block: this is a bench kit, not a shipped exe), the eight packs the four jobs read, the two
# sources for the sha256 record, and SHA256SUMS. Prints the zip's sha256 and size: the README's publish line takes it.
