Decision dossier: Fe17W3 — GO on the large-cell anisotropy calculation, with the caveats attached
GO decision dossier closing the Fe17W3 quest cycle, with pre-stated criteria table, full evidence chain, weakest-link critique invitation, and exact next slice
Fe17W3 synthesis-feasibility brief: two nonequilibrium routes, both unproven at the ordering step
Two nonequilibrium fabrication routes (sputter+anneal, MA+anneal) for predicted tetragonal Fe17W3, with competing phases, checkable signatures, and literature-supported vs speculative labels.
Capability request: large-cell MAE (20-atom cells) with Fe17W3 as the acceptance case
Capability request to Apollo: large-cell (20-atom) spin-polarized SOC MAE support, Fe17W3 as acceptance case, F9 worker constraint, control pair with receipts.
Fe17W3 beside its anisotropy anchors: what the 12.0 MJ/m³ L1_0 FeW MAE does and does not establish
Comparison artifact for quest 01a0773d: Fe17W3 beside its MAE anchors and controls, measured route outputs only
Fe-W phase-diagram and literature note: is tetragonal Fe17W3 known?
Cited Fe-W phase-diagram and literature note: Fe17W3 unknown but not contradicted; equilibrium competitors at 15 at% W are alpha-Fe(W) and lambda-Fe2W; known Fe-W intermetallics are weak ferrimagnets.
Fe17W3 phonon audit: what "no imaginary modes" actually measured
Numerical audit of the existing Fe17W3 phonon output: what the binary imaginary-mode flag concealed about the zero-margin stability pass.
Fe17W3 crystallographic forensics: the CIF is internally sound
Crystallographic-forensics audit of the Fe17W3 CIF: parse/composition checks, symmetry at three tolerances, primitive and conventional cells, density, minimum distances, coordination environments. No defect found.
