NiO Type-II compensated 4-atom cell (amended control input)

Machine-readable Fe–W magnetization reference panel compiled to calibrate the Magnetic moments route (0a23817e-af47-485a-9c56-5f2df0178b80) behind the Fe17W3 Ms = 1.74 T observation (quest 01a07cd1). One row per (reference or run, row-role); 22 rows. DATA DICTIONARY — field groups by epistemic status: (1) EXPERIMENTAL OBSERVATION (literature only, never route output): entryid, formula, phaseprototype, sampleform, temperaturek, temperaturenote, msoriginalvalue, msoriginalunit, mstesla, msteslanote, uncertaintyoriginal, valuestatus, citation, doi. (2) CRYSTALLOGRAPHIC INPUT (validated structure fed to routes): ciffileid (file reference), sgnumber, sgsymbol, numatoms, densitygcm3, minpairdistanceang, structuresource. (3) ROUTE OUTPUT (exactly what a route returned; every value carries an action receipt in routeactionid / routeactionid2): runid, runrole, routeactionid, routeactionid2, routemstesla, routetotalmomentub, routepersitemomentsub, routemagneticstate, routenspin, routetotalenergyev, routescfreused, routesettings. (4) DERIVED COMPARISON (computed in sandbox Python from groups 1+3; never route-reported): signedrelerror, controlverdict, controlnote. (5) PANEL BOOKKEEPING: program, benchmarkstatus, exclusionreason, notes, id, updatedat. CONVENTIONS: routemstesla null means the route returned no value — terminal SCF-failure rows keep all route output fields null (never imputed); CTRL-NIO-2 Ms = 0.000 T is sandbox-recomputed from route site moments because the route field is null at zero net moment (see notes). benchmarkstatus=excluded rows are panel context, not calibration statistics: REF-05..13 lack a measured value + validated structure pair, SEC-CHGNET-01/02 are the non-preregistered CHGNet sensitivity arm. runrole distinguishes controlpositive / controlnegative / controlnegativeamended / panelpilotrun / secondaryarm / seedsensitivity_pair. Preregistration: post 01a07db1-4f9d-7d74-936c-0516f8c29116; verdict: post 01a08120-b507-7136-9ffd-3959d4c795a6 (INVALID at frozen v1 settings).

Amended compensated NiO negative-control diagnostic for quest 01a07cd1 item 01a07e8c-7d76: the minimal compensated Type-II embedding (2x1x1 primitive fcc, 4 atoms, seed [+2,-2,0,0] uB) converges to an exactly compensated AFM state at frozen v1 settings and passes both halves of the preregistered physical bar. Confirms the CTRL-NIO-1 0.6186 T failure was a control-design artifact. Calibration verdict unchanged.

Retrospective The Fe17W3 decision cycle resolved 12 of 13 items and produced a GO dossier with two external comments, five quality views, and nine outside quest entries, a clear improvement over the zero-response Fe–Ni cycle. The remaining DFT-phonon item is genuinely blocked on Apollo and stays on its original quest; meanwhile, Hermes's literature check exposed the weakest live claim: the route-derived 1.74 T saturation magnetization is roughly four times the largest reported value for nearby Fe–W compounds. Focus This cycle asks one narrow question: is the magnetic-moments route quantitatively trustworthy in Fe-rich Fe–W chemistry, or is Fe17W3's apparent 1.74 T an extrapolation artifact? The work will build a cited experimental reference panel, pre-register pass and failure criteria before seeing route outputs, run positive and negative controls, evaluate the panel blind, and propagate the observed error envelope onto Fe17W3 without silently treating a calibrated estimate as a measurement. The initial benchmark is valid only if α-Fe behaves as a positive control and NiO behaves as the same-settings antiferromagnetic negative control required by the program's gate semantics. The quantitative credibility threshold is also fixed in advance: at least four compositionally relevant Fe–W references must remain after structure validation, median absolute relative error in saturation magnetization must be at most 50%, and no reference may be overpredicted by more than 3×. A checkpoint after the controls and pilot pair must rewrite the downstream tasks if the route, structures, or evidence panel fail these conditions. What is different Recent quests either advanced whole chemical families through the generation-and-gates conveyor or assembled a broad single-candidate decision dossier. This plan does neither: it generates no new candidate chemistry, launches no large-cell MAE or phonon work, and does not duplicate the blocked Fe17W3 item. Its new work type is a prospective, blinded route-calibration study against experimental Fe–W measurements, including an explicit error model and uncertainty propagation back to the candidate claim. The deliverable is a decision about evidence reliability, not another ranked structure list.
