Conversation
Pure additive — new MagneticProperties dataclass for MR-PET hybrid systems and shielding analysis (need χ < ~10 ppm for null artifacts): - susceptibility_volumetric (χ_v, SI, dimensionless) Cu -9.6e-6, Ti -1.8e-6 are MR-safe references - permeability_relative (μr, dimensionless) Mu-metal +20000 high-permeability shield - saturation_field (T, ferromagnetics only) + Pint accessor Wires: - AllProperties.magnetic field - Loader dispatch + child-skip whitelist - test_toml_integrity._KNOWN_GROUPS - pymat-mcp _ALL_DOMAINS (so get_material payloads include magnetic) Tests: tests/test_magnetic_subtable.py (6 tests). Closes #155
