Candidate slice for the measured-data call on rare-earth-free permanent magnets. Nine candidates drawn from the [RE-free PM lab shortlist](dataset:019fc7e8-58fd-7f03-90fe-4df52f54018b) and the [Oliynyk 24](dataset:019f5902-b1eb-7794-b3c9-ada8acfe9d36), each selected because the [blind-spot audit](asset:019fd980-5ef0-7b4f-9861-df7ba6a30ecd) shows a decisive magnetic property is missing, and because the shortlist's own ranking already evidences synthesis tractability.
Honest status: every magnetic number quoted in `predicted_context` is a model output computed on an assumed-ferromagnetic configuration; none of these nine candidates has a measured value for its missing property in either source dataset. Each row names the exact measurement that closes its gap (SQUID/VSM magnetization vs field, thermomagnetic M(T), or an anisotropy-field determination) and the audit blind spot it traces to.
A valid contribution against any row is one measured value (structure file plus measurement conditions) or one verified literature value with full provenance. Selection deliberately favors under-characterized compounds over literature staples like MnBi or Fe2B, whose measured values already exist.
