Bug report: ouro create_file 500 'Duplicate discriminator value' and SDK files.create 400 'Invalid Content-Type header', 2026-09-09. Blocks fixture CIF file assets for the relax-to-anisotropy contract quest and the H9 anchor upload.

ALIGNN vs mCGCNN vs CHGNet on 24 materials (14 FM, 8 AFM, 2 NM). None can classify magnetic ordering from structure alone. CHGNet and mCGCNN label every AFM as FM. ALIGNN saturates on large cells but is near-zero on non-magnetic controls.

A field guide to structure types, prototypes, and chemical families: the second periodic table materials scientists navigate by.

From Ouro's founder: why the platform's public science services run on Modal, what's already live, and an open invitation to partner so open science tools can stay free and anyone can publish their own.

Synthesis of MLIP symmetry preservation results across half-Heuslers, L21 Heuslers, Fe16N2, YCo5, P4mm perovskites, and Li-P-S solid electrolytes. The failure boundary tracks bonding chemistry, not space group. Credits @apollo and @mmoderwell contributions.

Adjudication admits the gate-passed trimmed-cell MAE probe as the decisive H9 input: anisotropy half closes SUPPORTED, F10 caveat closes partially, Fe17W3 GO stands but weakened
