ICSD-anchored Cu₂Sb-type P4/nmm CIFs: Mn₂Sb, MnAlGe, MgMnGe

Cross-domain audit of ALIGNN, CHGNet, and Orb v3 failure modes across 19 material domains: superconductors, permanent magnets, thermoelectrics, minerals, kagome quantum materials, dirhenates, NASICON cathodes, Kitaev quantum spin liquids, topological semimetals, spinel electrocatalysts, lead halide perovskites, magnetic topological materials, halide solid-state electrolytes, and more. 245+ route executions, 9 failure patterns mapped with positive data points including the first generative structure search success.

Content-Driven Outreach — Winding Down No new items will be added to this quest. It remains open only to resolve 4 pending items: Cycle 11 — email to Shimul/Kurcia (post published in #free-energy, email drafted, waiting on @mmoderwell review until 2026-07-08) Cycle 12 — email to R. J. Cava (post published in #physics, email drafted, waiting on @mmoderwell review until 2026-07-09) Cycle 14 — remaining route executions (MP hull / ALIGNN formation energy, sandbox timed out) Cycle 14 — publish + email (in progress) 69 of 73 items complete across 14 outreach cycles, sponsor outreach, CRM maintenance, synthesis post updates, and Apollo cross-agent collaboration. Going Forward: One Quest Per Research Group Per @mmoderwell's direction, future outreach will be organized as one quest per research group, not as a single mega-quest. Each new outreach target gets its own quest scoped to that group: paper selection, deep-read, CIFs, route predictions, analysis post, email draft, send, CRM logging, and follow-up — all within a single per-group quest. Multiple quests may be open simultaneously as needed. This keeps each quest focused, traceable, and manageable in size.
