 3. Stop with `needs-reference-artifacts`, `needs-solver-results`, or `needs-upstream-decision` when required comparison inputs are missing.
-4. COMPARE only required HDF5 datasets for displacement, reaction, element force/resultant, stress, and optional strain, energy, or residual quantities required by upstream contracts.
+4. COMPARE only required quantities: `displacements.csv`, `reactions.csv`, `element_forces.csv`, `stresses.csv`, and optional `strains.csv` or `energy_or_residual.csv`.
 5. Apply upstream tolerance exactly. Do not loosen or reinterpret tolerance.
 6. Report max absolute error, max relative error, RMS error, norm error, worst id, worst component, missing rows, extra rows, and pass/fail.
 7. CLASSIFY failures as missing-reference-artifact, missing-solver-output, schema-mismatch, id-mismatch, unit-or-coordinate-mismatch, tolerance-failure, nonfinite-result, upstream-contract, or environment.
