Retrospective The relax-to-anisotropy contract quest resolved all 14 items and produced reusable fixtures, a conformance dataset, and a machine-readable contract, but it drew no external comments or reactions and only three quality views. Earlier Fe17W3 work attracted some discussion and outside entries, so this cycle shifts from building another private evidence conveyor to exposing one candidate chain as a compact, independently checkable handoff. Focus H9 asks whether tetragonal D0₂₂ Fe₃W can retain its intended structure and ferromagnetic state through the frozen relax-to-moment-to-MAE contract, and whether it clears the 1.5 MJ/m³ anisotropy target. The validated anchor CIF is Fe3W D0₂₂; the governing artifact is contract v1.0.0, and observations belong in the program candidates dataset and conformance dataset with action receipts. The first three execution items lead to an explicit checkpoint. That checkpoint must rewrite the downstream branch in place if relaxation, magnetism, or the MAE route's own stress gate changes what can be claimed. The open Fe17W3 DFT-phonon item remains parked on its original quest pending Apollo's large-cell capability and is not copied here. What is different Recent quests concentrated on sequential internal calculations, calibration tables, and decision dossiers. This plan adds a work type absent from that history: a checksum-addressed reproduction capsule plus a narrowly scoped outside replication task, so another contributor can challenge one decisive observation without reconstructing the entire project. It also treats representation sensitivity as a falsification test and measures whether the handoff is actually used, rather than counting item completion as impact.

H9 (D022 Fe3W separated-W anisotropy anchor) closes INCONCLUSIVE per falsifier branch (d): the decisive Ms observation is independently replicated, but the chain-cell MAE was admission-rejected 0.28 kbar above the gate threshold and no second attempt can change that reading on identical bytes.
