# Benchmark Beam Model Notes

- File: `machine/benchmark_6MV.mat`
- Source: copied from matRad's bundled generic photon machine data
- matRad provenance: `https://github.com/e0404/matRad/commit/c014dc82d620bace0836eb8cc420fe33c19cdb87`
- Purpose: frozen research benchmark beam model for reproducible IMRT replanning
- Scope: benchmark-only, not a commissioned clinical linac model
- Integrity: verify against `machine/benchmark_6MV.mat.sha256`

This task is an open-source research replanning benchmark. The beam model is
included so the agent does not need internet access, machine-data authoring, or
local commissioning work.
