workload_list and workload_fetch: download a test program once from this project's releases, check the
SHA-256 this package pins and keep it in ~/Library/Caches/metal-gpu-trace. Claude Code asks before every
download (anthropic/requiresUserInteraction).
perf_record records a fetched test program with workload, api and dim.
First test program: bgfx 17-drawstress for macOS arm64 and Windows x64, built from source by .github/workflows/workloads.yml (release workloads-1). Recorded on an M1 Pro, it gives the same encoders per
frame as a local build (2 in native Metal, 7 in D3D12 under Mullion) and FPS within 4 %.
compare-layer prompt: records a test program in native Metal and under a translation layer, then diagnoses and
compares both runs.
