CLI
The days CLI, the legacy CLI, the LeanGuard tools, and the retained measurement binaries.
User-facing entry points:
days(packagedays): compile one scenario and run it on the Scalar, CPU, Metal, or CUDA engine of Days AGO.days-legacy(packagedays-legacy): run one scenario on the frozen Legacy Days simulator.leanguard-run: generate or discover legacy traces and invoke the Lean checkers.leanguard-testgen: generate, replay, and minimize checker corpora.
The root package also has two measurement binaries. They are validation tools, not a stable general-purpose CLI:
device-sizing-report [FIXTURE]: lowers one fixture and prints the default Metal and CUDA device plan, plane by plane, using host arithmetic only. It allocates no device memory and does not run the simulation.sustained-benchmark: the timing harness for the sustained device fixtures. It builds only with--features metalor--features cuda.
