Supplementary data for: Transport-equivalent grouping in radiation-response materials: a bounded 5 MeV study with evidence for pi-class structure

This record contains the brief supplementary data package for the manuscript “Transport-equivalent grouping in radiation-response materials: a bounded 5 MeV study with evidence for pi-class structure.” The package contains flat support files for the visible manuscript objects only: Table 1 main packet values and frozen 5 MeV lock summary; Table 2 leave-one-out robustness summary; Table 3 cross-energy 3/5/7 MeV summary; Table 4 same-family transport-side support summary; Figure 1 material-role map; README and SHA256 checksums. This package is a manuscript-support layer, not a second paper and not a raw laboratory archive. The main claim remains the declared 5 MeV ten-material study set. The figure map remains bounded context rather than a broader family-law claim.
