fix: pass material to PointsGridDataProvider at every call site - #357
Conversation
wode's PointsGridDataProvider now derives KPPRA and the reciprocal vector ratios from the material rather than assuming a single atom and omitting the ratios. It raises when the atom count cannot be derived, so every construction must supply `material=`. 34 call sites across 17 notebooks plus `apply_scf_kgrid`, which is the one notebooks reach indirectly -- it now takes `material` and threads it through, covering interfacial_energy and surface_energy. Multi-material notebooks resolve the material per unit rather than guessing: - valence_band_offset: three pw_scf units on three slabs of differing atom count, resolved from the subworkflow's role via materials_by_role. Raises on an unrecognised name instead of falling back to the interface material, which would have silently persisted the wrong KPPRA for both slabs. - defect_formation_energy: the single pw_scf is the defective cell; the pristine energy is fetched, not computed. - equation_of_state: base_material -- create_strain(scale_factor=) is isotropic, so atom count and ratios are invariant across the series. Ordering: this must merge before the new wode publishes. config.yml pins bare `mat3ra-wode`, so JupyterLite takes latest at runtime; the published wode ignores `material=` (extra='allow'), making this change a no-op until then.

The tests assert the derived KPPRA and reciprocal vector ratios, which only exist in the unpublished wode change this depends on; against the published version they read -1. Pin to the branch commit so CI exercises the real code. Repoint to the released version once wode publishes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Pass the slab material to apply_scf_kgrid.
When SCF_KGRID is set, the provider derives KPPRA and reciprocal-vector ratios from material. The job uses saved_slab, but this call supplies bulk_material, so the SCF grid can use bulk metrics.

Remove the mutable default argument.
reciprocal_vector_ratios is created once at function definition time. A future mutation can leak state between tests, and Ruff reports B006 for this line. Use None and initialize the list inside the helper.

…de pin wode now types the provider's material field to Material, so a SimpleNamespace no longer validates.
The SOF-7990 fix is in 2026.8.26.post1, so the temporary git pin can go.

Summary
Part of SOF-7990. wode's
PointsGridDataProviderhad no material, so it silently defaulted theatom count to 1 and never emitted
reciprocalVectorRatios— both are properties of the material.Two consequences: KPPRA was under-reported by a factor of the atom count (a 2-atom cell on a 4×4×4
grid recorded 64, not 128), and the absent ratios made the k-grid Important Settings form silently
reject every edit on a cloned job. wode's fix (mat3ra/wode#162) now derives both from
materialand raises when the atom count can't be derived, so every construction needs
material=.This updates all 34 call sites — 17 notebooks plus the
apply_scf_kgridhelper, which twonotebooks (
interfacial_energy,surface_energy) reach indirectly.Multi-material notebooks resolve the material per unit rather than guessing:
pw_scfunits on three slabs of differing atom count, resolvedfrom the subworkflow's role via
materials_by_role. Raises on an unrecognised subworkflow nameinstead of silently falling back to the interface material.
pw_scfis the defective cell; pristine energy isfetched, not computed.
base_material—create_strain(scale_factor=)is isotropic, so atomcount and reciprocal vector ratios are invariant across the series.
pyproject.tomlpinsmat3ra-wodeto the wode branch commit so CI exercises the real derivationinstead of the published version, which silently accepts
material=and ignores it(
extra="allow") — repoint to the released version once wode publishes.Ordering
This must merge before wode publishes.
config.ymlpins baremat3ra-wode, so JupyterLitetakes latest at runtime; a published wode with this fix would make every notebook here raise
until this PR lands.
