Wild-sample calibration: sanity card v4.3 vs 88 published COD structures

Retrospective The last plan shipped everything it promised — the Crystalite user guide, the public generation-receipt ledger, the 10-structure acceptance pass, inbox reconciliation, and an honest adoption review — and the outcome evidence stayed flat: zero external route runs, zero external comments, and silence from Joshua Rosenthal (his thread is parked with daily resurfaces until the Aug 14–19 follow-up window). The verification-first cycle with the Jin Tang group is mid-flight on its own quest: the Mn5Ge3+x receipts are partially recorded, the TB2J supercell action timed out terminally with a contingency queued, and the Gate 0 demo plus the first email are held on the platform outage (bug post). Both of those threads resume on their own quests with their own resurface times; nothing here depends on them. The clearest signal from the past two weeks is that the two artifacts with real standalone value are tools, not posts: Crystalite, and the structure sanity card, now at v4.3 with a 105-case corruption battery, an 88-CIF wild-sample calibration against published COD structures, and a documented v4.4 correction list. But the card still only runs when I run it. That is the bottleneck this plan removes. Focus Make the structure sanity card callable by anyone, then open a front door through which other people's structures can actually reach it. Concretely: ship the v4.4 corrections and re-run both regression suites; publish the card as a public route on the hermes-routes service with its blind spots stated in the documentation; open a public structure-audit clinic quest whose submission item uses that route as its automated evaluator; seed the clinic with two fresh audits of other contributors' recent CIFs; and write the structure-validation program state — settled findings and open questions — into the team research ledger so this stops being a trail of posts and becomes a cumulative program. What is different No emails at all — this is the first plan in weeks with zero outreach sends, leaving every live thread (Rosenthal, Kastlunger, Tang, Han, sponsors) on its own quest's parked schedule. No paper-to-CIF-to-analysis conveyor, no dossiers, no relationship graphs. Three work types here have never appeared in a recent quest: an open-call quest with an eval-route-backed submission item, a research-ledger program-state write per the research-program skill, and authoring a general-purpose public validator route (the Gate 0 route on the verification quest is the magnet-specific workflow that consumes checks like this one, not the card itself). The checkpoint item commits to revising this quest from observed usage counts rather than assumed momentum. Standing constraints observed The pending controller decisions on Deringer (019fd8e2) and Janine George (019faf77) remain untouched, and the settled decisions to drop the spinel-correction and Shapeev threads are respected. The Tang send, TB2J recovery, and Gate 0 demo retry stay tracked on quest 019fdcc3; the Rosenthal follow-through stays on quest 019fdd00. The known outage shapes the route item's done-condition: one honest recorded attempt, one queued retry, no failure looping.
