Retrospective 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." Focus 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 @mmoderwell's 2026-08-06 direction, no invitation goes out until the target-specific artifact exists — here the artifact is the call itself. What is different 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. Guardrails 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.
