For narrow questions, load one file (e.g., only tallies.md for a filter question). For cross-cutting tasks, load the files that span the question (e.g., tallies.md + statepoint.md for construction-through-readback). Never load all docs indiscriminately — choose based on what the task actually requires. --- ## Cluster A — Build a Model **Materials / nuclides / enrichment / density / get_activity / get_decay_heat / decay heat / waste classification / waste_disposal_rating / NCrystal / from_ncrystal / ncrystal_cfg / Macroscopic / material Mixture / mix_materials / Nuclide class / Element class / activation material:** Read `docs/materials.md` **CSG geometry — surfaces, cells
