The direct
convert_celldmtests do not cover the full reader behavior. The CP suite loadsibrav=8, but its fixture has a.celfile. The reader uses that file fordata["cells"], so an incorrect cell fromload_param_filecan pass the existing virial assertions. The PW/SCF suite coversibrav=1withA, but no reader test covers nonzeroibravwithB,C, or cosine values.Add focused CP and PW/SCF fixtures without overriding

cells: update resolve_celldm and abc_to_celldm to reject missing or mutually
exclusive celldm versus A/B/C/cosine inputs rather than filling absent values
with zero, then update convert_celldm to require finite positive scale and ratio
values, enforce per-ibrav cosine ranges, validate all three cosines for
ibrav=14, and reject non-positive volume terms including term == 0. Ensure the
PW, CP, and SCF readers validate through this path before using the resulting
cell.

NEEDS HUMAN REVIEW / exact-head CI has not executed.
Reviewed the complete 3-file change against the repository guidance, linked issue #408, current discussion, and Quantum ESPRESSO's latgen conventions. The lattice-vector formulas for the supported ibrav families are consistent with QE's definitions, including the alternate negative-index conventions; the new validation rejects non-positive required ratios, invalid/degenerate cosine combinations, and unsupported ibrav values rather than silently returning an identity cell. The A/B/C → celldm path also preserves the Angstrom/Bohr conversion boundary before the common lattice generator, and scf.get_cell now shares that path for nonzero ibrav.
The earlier review finding around incomplete/invalid lattice parameters is addressed on this head with explicit validation and regression cases. I did not find a new high-confidence functional or numerical blocker in the current diff. One coverage gap remains worth closing before final sign-off: the new tests are strong at the convert_celldm level, but there is still little reader-level coverage proving that a nonzero-ibrav PW/SCF or no-.cel CP input using the A/B/C/cosine form produces the expected final cell with the correct unit scaling. I am treating that as a verification gap rather than a demonstrated correctness blocker.
I cannot approve this head because none of the exact-head GitHub Actions have actually run: test Python import, Type checker, Python package, and Benchmark are all action_required, and there are no completed check-runs for this SHA. Please let the fork workflows execute (or obtain equivalent trusted CI evidence) before merge.

Description
Extend Quantum ESPRESSO lattice support so that
ibravvalues beyond{0, 1, 2, 3, -3}are handled correctly. Closes #408.Previously:
dpdata.formats.qe.traj.convert_celldmsilently returnednp.eye(3)for anyibravoutside{1, 2, 3, -3}(only emitting aUserWarning), so a CP trajectory without a.celfile produced a wrong unit cell.dpdata.formats.qe.scf.get_cellraisedRuntimeError("ibrav > 1 not supported yet.")for everyibravother than0and1.Type of change
Scope / behavior
convert_celldmnow implements the fulllatgentable from QE'sModules/latgen.f90foribrav∈ {1, 2, 3, -3, 4, 5, -5, 6, 7, 8, 9, -9, 91, 10, 11, 12, -12, 13, -13, 14}. Rows of the returned 3×3 matrix are the lattice vectors a1, a2, a3, in the same length unit ascelldm[0](unchanged foribrav1/2/3/-3). An unsupportedibravnow raises instead of silently returning an identity cell.To avoid duplicating the parameter logic, the PW (
scf.get_cell) and CP (traj.load_param_file) readers share two new helpers:abc_to_celldm/resolve_celldm: convert the crystallographic input form (A,B,C,cosAB,cosAC,cosBC, in Å) tocelldm(1..6)(Bohr, ratios), mirroring QE'sabc2celldm, so both thecelldm-style and theA/B/C-style inputs work for non-zeroibrav.ibrav == 0(CELL_PARAMETERS) is untouched.Tests / verification
tests/test_qe_cp_traj.py: replaced the oldtest_case_null(which asserted the identity-cell bug foribrav=8) with golden 3×3 cells for all 20 supportedibravvalues, plus a rotation-invariant check of lattice-vector lengths, inter-vector cosines, and cell volume for a representative subset, plustest_unsupported_ibrav_raises.python -m unittest discoverintests/: 2391 tests, same 69 errors / 287 skips as the pre-change baseline (all from missing optional deps: ase, parmed, pymatgen, rdkit, deepmd, gaude).
