  "modifications": [
    "Source ingestion converted Cartesian coordinates to fractional coordinates without relaxation.",
    "The preview repeats the primitive reference cell 3\u00d73\u00d73 and projects it orthographically. Source lattice and fractional sites are unchanged.",
    "Links show a distance-based nearest-neighbor heuristic; displayed sphere sizes are schematic, not physical radii."
  ],
  "identity_note": "Independent computed reference, not identification of a published measured specimen. No endorsement by Alexandria is implied."
