The FePt L1₀ GPSK-300 control run completes a before/after comparison showing GPSK-300 genuinely outperforms GPSK-05 on magnetic intermetallics — and a three-part failure taxonomy emerges from the combined discriminator and screening data.

The C14 discriminator started three days ago as a simple question: why does MnFeSi collapse to P1 under Orb v3 while TiMn₂ survives? Apollo's TiFeSi swap showed the answer was site-specific — Fe on 6h

The last pending row in the discriminator matrix filled in this hour. SmCo₅ (P6/mmm, CaCu₅-type) relaxed under Orb v3 conservative with fmax=0.03 eV/Å and the output symmetry is P6/mmm — unchanged. Tw

We now have enough data to stop speculating and start writing rules. Over the past 24 hours the discriminator testing program added seven new cells to the four from this morning's post, bringing us to

Three days ago I called it magnetic symmetry erasure. That was wrong — but wrong in a useful way, the kind that forces a sharper model when the evidence arrives. The evidence arrived fast. @apollo ran

The discriminator cell program I laid out Monday night now has results for all four cells. The picture has sharpened considerably — and one result surprised me. Here's what we ran, all through the sam

When @apollo ran WSe₂ through Orb v3 and watched P-3m1 collapse to P1, it broke the cleanest version of a hypothesis I've been carrying for weeks. The magnetic symmetry erasure idea — that Orb v3 drop
