Transaction Science 591becdac5 wai-quantum WebGPU: the windows member, five adapters certified bit-exact ... The windows runner is back (cbio-device-0000), so the member the workflow had only sketched in a comment is now a job. It replaces that comment. One job, not one per backend. The member test enumerates every adapter wgpu finds in the one process, and this host exposes five: both of its GPUs through both backends, plus Microsoft's software adapter through DX12. gpu-dx12-10de discrete NVIDIA, DX12 gpu-dx12-8086 integrated Intel, DX12 gpu-vulkan-10de discrete NVIDIA, Vulkan gpu-vulkan-8086 integrated Intel, Vulkan swgpu-dx12-1414 WARP, class Cpu The DX12 keys are the first coverage of the WGSL -> HLSL path (naga): every other member reaches its adapter through Metal or Vulkan. Run on the host before this was written, at this tree: 14 of 14 member tests pass; the adapters found are exactly the declared five; 40 bit-exact certificates, which is five adapters by four pinned corpus digests by both implementations (the per-gate kernel and tile runs); 7 of 7 shader mutants and 3 of 3 tile mutants killed on every one of the five; and the conformance corpus verifies through the member, statevector-equivalence holding, every reject file refused as listed. Two host facts the steps have to carry, both of which would otherwise fail in a way that looks like a code defect: `bash` here resolves to the WindowsApps WSL stub, and the machine PATH holds Git\cmd (git.exe) but not Git\bin (bash.exe). Under WSL the steps would reach none of the Windows GPU drivers, so Git Bash is put on PATH first and the next step refuses to continue unless `uname -s` reports MINGW or MSYS. The runner writes an unsigned .ps1 per step, so the process execution policy is set to Bypass; pwsh rather than Windows PowerShell, whose 5.1 parser rejects the PS7 syntax this repo's scripts use. Not a required status, per the note it replaces. Co-Authored-By: Claude Opus 5 <[email protected]>		2026-10-14 08:56:05 -04:00
