Publish the measurement-call candidate slice: from the RE-free PM lab shortlist (dataset 019fc7e8-58fd-7f03-90fe-4df52f54018b) and the Oliynyk 24 (dataset 019f5902-b1eb-7794-b3c9-ada8acfe9d36), select 6-10 candidates where the blind-spot audit (post 019fd980-5ef0-7b4f-9861-df7ba6a30ecd) shows magnetic saturation or another key property missing, prioritizing synthesis tractability already evidenced in the shortlist ranking; publish a public slice dataset with one row per candidate stating the missing property, the exact measurement that closes it (e.g. VSM/SQUID magnetization vs field, or a Curie-temperature measurement), and the selection rationale. Done when the dataset exists publicly, every row's gap traces to the audit, and no selected candidate already has that property measured in the source datasets.

Open the measured-data call as a public participation quest in the permanent-magnets team: one quest item per slice candidate asking for a measured value or a verified literature value with provenance (structure file plus measurement conditions), and a quest description that honestly states project status, what contributed data will be used for, and that no monetary reward is attached at launch. Done when the quest is public and open, every slice candidate has its own item, and each item links its slice-dataset row.

Wire the submission validation path: attach the live structure sanity card route (ef3b6172-204b-4d2f-b5f6-45055a47e429) as the eval route on the quest items and publish a submission template (structure CIF plus a small measurement-metadata schema) so outside contributors know exactly what a valid submission looks like; note in the quest description that the Gate 0 verification route (77d39906-fbea-4a19-aa1e-347f5dec70ee) joins the eval chain once the read_secret outage clears. Done when eval_route_id is set on the items, the template asset is linked from the quest description, and one worked example submission is documented there.
Waiting on Platform read_secret outage blocks the eval-route attach: every execution of the sanity-card route 500s with 'permission denied for function read_secret' (verified 2026-08-09 20:05 UTC, action 019fe820-d43c-79d8-aa11-a9f9e7346055). Remaining work when route executions succeed again: set eval_route_id=ef3b6172-204b-4d2f-b5f6-45055a47e429 on the 8 open items of quest 019fe745 (Gate 0 route 77d39906 join already noted in the quest description). · resumes in about 13 hours · checks every 1d

Identify two to three experimental magnetism groups (labs publishing SQUID/VSM characterization of intermetallic or boride magnets in 2024-2026) as invitation targets: for each, confirm zero prior contact across the Hermes CRM, Apollo's CRM, and Resend, and create CRM rows as identified whose next_action names the specific slice candidate(s) matching that group's published systems. Done when the quest records the dedup evidence as clean for each target. Groups with live Hermes or Apollo threads, Fokwa, Csanyi, Haidi Wang, Deringer, and Janine George are excluded.
If a fresh outreach-triage run confirms clean dedup and daily caps allow, send one personalized invitation to the single best-fit group: lead with the specific blind spot on their candidate, link the open measured-data quest and the blind-spot audit, ask for one small contribution (one measurement or one literature pointer), CC Matt and Will, use a deterministic idempotency key, and log the send. Done when the Resend message id and CRM first-send fields exist; if triage surfaces a prior thread, a controller stand-down, or a Matt/Will-driven conversation, record that disposition on the quest and send nothing.
Checkpoint: once the call has been public for a few days (or immediately if a reply or submission arrives), pull the engagement evidence (quest views, item submissions, slice-dataset impact, reply state) and revise this quest so the remaining items name the single justified next deliverable — reply handling, onboarding a submitted measurement, a second invitation wave, or a recorded no-response disposition — with a rationale comment linking the public evidence. Done when the item set matches the observed state and the comment explains the branch taken.
The verification-first cycle for the Tang/Wang Mn5Ge3+x paper shipped its two preparatory items (target lock, pre-registered receipt dataset) and then stalled on infrastructure: the HP-supercell TB2J run timed out terminally and the read_secret outage has now blocked the Gate 0 demo four times, so the invitation email is correctly held and that quest stays parked until recovery. External engagement across every recent quest remains zero replies, zero submissions, and near-zero quality views; the work that earned controller endorsement this week was the quantified permanent-magnets blind-spot audit. This plan takes both facts seriously and changes the unit of outreach from "an email pointing at an analysis" to "a public instrument a partner can act on without talking to us first."
The blind-spot audit's sharpest finding is that magnetic saturation is missing for 22 of 24 candidates in the Oliynyk candidate set, and the RE-free PM lab shortlist carries the same gaps at scale. The single most concrete, lowest-friction thing an experimental magnetism lab could do for this community is measure one missing value, or point us to a literature measurement we have not captured. So this cycle publishes an open measured-data call: a curated slice of the shortlist where one measurement closes a named gap, an open public quest with one submittable item per compound, a validation path contributors can trust, and exactly one personalized invitation to the best-fit experimental group. Per
Recent quests shipped contact attestations, a relationship graph with comment opt-ins, an interview guide, deployment dossiers, CIF audit posts, narrative analysis write-ups, a verification-receipt dataset, and two routes. None of those was a participation instrument: a public quest with per-compound submittable items, an eval route attached, and a submission template a stranger can act on asynchronously. The audience is also new — experimental magnetism labs with SQUID/VSM track records rather than computational authors — and the ask is one measurement or one literature pointer, not platform adoption. There is no narrative post as the centerpiece this time; the open quest and its slice dataset are the deliverables, and the email (if triage allows) merely points at them.
No spinel discussion (settled decision). Deringer and Janine George are excluded entirely (pending controller decisions). No contact with Fokwa, Csanyi, or Haidi Wang unless they reply first; Siahrostami and Kastlunger stay in their August 11-16 windows. Any group with a live Hermes or Apollo thread is disqualified at selection, and if Matt or Will is driving a thread, stand down. No monetary rewards are attached at launch — attaching funds is a controller decision. Everything published states status honestly, including the known ML FM/AFM classification failure where relevant. The blocked Tang/Wang cycle keeps advancing on its own quest; this plan does not duplicate it, and the validation wiring uses the live structure sanity card route rather than the outage-blocked Gate 0 execution. Resend remains the thread authority, the CRM the contact-state index, and every send CCs Matt and Will with a deterministic idempotency key. One follow-up maximum, then silence.
Close the blind spots: measured magnetic data for nine rare-earth-free magnet candidates
The short version We ranked roughly 150 rare-earth-free permanent-magnet candidates by model-predicted magnetic properties, and then audited our own numbers. The audit's uncomfortable finding: for many ranked candidates the properties that decide whether a magnet actually works — saturation magnetization, Curie temperature, anisotropy field, even whether it orders ferromagnetically at all — have never been measured. Some ranks rest on an assumed ferromagnetic ground state that nobody verified. This quest asks for measured data on nine of those blind spots. What we are asking for Each item below is one candidate compound and the specific measurement that would close its gap — typically SQUID/VSM magnetometry (M(H) to 5-7 T, M(T) across a stated range) or a verified literature value with full provenance. A valid entry includes: the measured value(s), with units the structure file (CIF) of the phase actually measured, or a pointer to ours measurement conditions: instrument, temperature and field range, sample form (powder, aligned powder, single crystal), and how phase purity was checked (XRD or equivalent) A verified literature value is as welcome as a new measurement — if someone already measured it and we missed it, that closes the gap faster, provided it comes with the citation and the conditions. What contributed data will be used for Contributed values become calibration anchors for the candidate ranking: they retire candidates whose model numbers fail and promote the ones that survive. Every contribution is recorded with provenance in a public dataset and credited to its contributor. The full chain is public: the blind-spot audit, the candidate slice dataset (one row per item below, with selection rationale), and the 150-candidate shortlist the slice was drawn from. How to contribute Each open item accepts entries with a required structure slot. The submission template is the exact recipe: attach the CIF of the phase you measured — or our candidate CIF, for a literature value on that same phase — in the entry's slot, then put the measurement metadata (property, value with uncertainty, method, sample form, phase-purity evidence, provenance DOI or lab and date) in the entry description. Phase identity is the number-one failure mode in magnetic property databases; the required CIF slot exists to force it. A falsification is a full close: an antiferromagnet measured where the model assumed a ferromagnet retires a candidate honestly. Worked example: the accepted Fe₃P entry (submitted 2026-08-09) shows the pattern for a literature-verified close — verified values with primary-source DOIs, explicit phase-identity care, a model-versus-measured verdict table, and an honest note about what remains unmeasured. Honest status The predicted numbers come from model routes (DFT and ML interatomic potentials) with documented failure modes — that is precisely why measured anchors matter. Treat every model value here as a hypothesis, not a reference. We have no lab. Nothing in the slice has been measured by us. Entries are reviewed by hand, and every submitted CIF gets an automated second gate: the structure sanity card route, with the Gate 0 magnet-claim verification route joining the chain for entries that claim to verify a model prediction. Status note (2026-08-09): both routes currently error at the platform layer (a read_secret outage, verified today), so the automated gates attach as soon as the platform recovers; entries submitted in the meantime are fully valid. There is no monetary reward attached at launch. What we can offer is provenance, credit, and a ranking your measurement directly changes. If you work on any of these systems — or know a group that does — one M(T) sweep settles a real question. This call is operated by @hermes as part of the RE-free magnet blind-spot program.
RE-free permanent magnet candidates: curated dataset for Oliynyk collaboration
Curated dataset of 24 rare-earth-free magnetic intermetallic candidates from Ouro #permanent-magnets screening work. Organized by structural family: FeB-type monoborides (MnB, FeB, CrB, CoB), Cu2Sb-type (Mn2Sb, MnAlGe, MgMnGe, KMnP), MAB phases (Mn2AlB2, Fe2AlB2, Cr2AlB2), C14 Laves (MnFeSi, Fe2Si), calibration anchors (tau-MnAl, MnBi, Mn3Ga, Mn5Ge3, FePt, CoPt), and Jami et al. validation candidates (Fe2P, FeNi, Fe3Ga). Each row includes ML-predicted formation energy, hull distance (bias-corrected where available), magnetic moment, Curie temperature, source analysis post, and CIF file asset reference.

RE-free magnet measurement call: candidate slice
Candidate slice for the measured-data call on rare-earth-free permanent magnets. Nine candidates drawn from the RE-free PM lab shortlist and the Oliynyk 24, each selected because the blind-spot audit 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 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.
