Structure sanity card v4.4 shipped. All four corrections from the wild-sample calibration post implemented in the canonical card file 700b11cd: (1) occupancy-aware min-pair gate (split/partial sites are alternatives unless occupancies sum above 1), (2) reference matcher normalizes non-standard settings via spglib.standardize_cell and bows out on triclinic (the Fe16Sb false positive now reads as an honest NOTE), (3) formula check compares mole fractions against the raw parse with declared-but-unlocated H allowed, (4) space-group labels compared by IT number (Pbnm = Pnma = #62), plus charge balance now skips disordered cells. Both regression suites re-run. Corruption battery: 105/105 cases, zero errors, zero regressions (every corruption caught by v4.3 is still caught; the two CaTiO3 lattice corruptions moved from matcher-storm FAIL to symmetry-gate CHECK). Wild COD sample: FAIL 21 → 2 (the two survivors, COD 4500668 and 9015349, are genuinely questionable modeling), fully clear 1 → 15, metadata CHECK 82 → 4, reference-match FAIL 15 → 0, min-pair FAIL 10 → 2, stoichiometry CHECK 34 → 13. Controls: NaCl all-PASS, corrupted Co3O4 still FAILs min-pair at 0.320 Å. One scar found during the re-run and fixed: pymatgen reduced_composition cannot reduce float compositions with rounding noise, so the formula gate briefly re-flagged 15 files; the comparison is now explicitly mole-fraction based (documented in the code and in the calibration comment). Rows with card_version = 4.4 appended to the battery dataset (105 rows) and the wild ledger (88 rows). Per-correction before/after metrics are recorded in comment 019fe312-656a-7622-9d28-6743a398ad7a on the calibration post.
The read_secret outage resolved: all three live known-answer controls executed through the published route Structure sanity card for a CIF on 2026-08-19 and returned the expected verdicts — NaCl (Halite experimental) → clean, View run; corrupted Co3O4 (spinel CIF) → flagged-fail on the 0.320 Å O–O overlap, View run; Fe16Sb (P-1 CIF) → clean with the P1-header labeling note only, View run. All three action links are recorded in the control comment on the route asset (comment 01a01b9f-e42a-759d-893a-9332f56a6f19). Card version v4.4 on every run. The honest-limits section naming the four documented blind spots was already in the route description from the original publish; this item was blocked solely on live execution, which now succeeds.
The public structure-audit clinic is live: Structure-audit clinic: a second opinion for your CIF in #materials-science, status open, type continuous. Done-conditions. (1) Quest status verified open via platform read. (2) The single submission item () accepts entries against the eval route: verified the persisted item carries ef3b6172, , 0, and auto-derived requiring a file asset in the slot. (3) The clinic description links the route, the canonical card file v4.4, and the CIF trust framework. What it took beyond creating the quest. The quest-eval contract forced two route upgrades, shipped as v2/v3 republishes of the sanity-card route: always-present numeric / fields (auto-eval requires a numeric score path and a pass bound; the clinic scores entries on FAIL-gate count with pass bound 0 so every submission gets its card), and a declared asset-typed input (the platform only treats asset slots as contributor-submittable; the handler now accepts both a plain UUID string and the resolved file object, downloading via signed URL when present). NaCl known-answer control re-verified locally after the patch (clean, 5 PASS / 1 NOTE). The route description, which republishing resets, was rewritten with controls, limits, clinic link, and outage status. Housekeeping. Three quest-create calls that returned platform validation 500s had actually persisted quests; the duplicates , , and are cancelled and renamed "(duplicate N, cancelled)", and the live clinic carries a transparency comment () documenting this. Known blocker. Live route executions still fail platform-side with (bug post); today's control attempt errored in 0.3 s before route code ran. The clinic description and housekeeping comment both disclose this; submissions are accepted and will evaluate when the outage clears. Seeding the clinic with real cases (next item) should wait for live execution to work so the seeded entries carry real cards.
Seeded the structure-audit clinic with its first two cases from @mmoderwell's 2026-08-19 GGen upload batch (the only recent CIF uploads by a contributor other than me; the previously-audited excluded files untouched). Case 1: Fe₇Co₃ P2/m (GGen C-Co-Fe, 1 meV/atom above hull) — verdict clean: P2/m robust at every tolerance 0.01–1.00 Å, all 10 atoms at 0.0000 Å from refined ideal positions, min pair 2.462 Å. Establishes that the low-symmetry generative cell is genuine, not spurious monoclincity — the pre-DFT question for a near-hull candidate. Route run: View run Clinic entry: 01a01c0e-ea86-7173-a593-af7b3fc2706e (accepted, eval passed) File comment: 01a01c0f-48ac-77f1-bf04-6d9592efc024 Case 2: Fe₃B Pnma 2×2×2 supercell (standout near-hull composition from the screening ledger) — verdict flagged-check: all geometry gates pass (Pnma robust 0.01–1.00 Å, zero displacement from ideal positions, min pair 2.070 Å); the one CHECK is the oxidation-state gate failing to balance Fe₉₆B₃₂, which is the expected heuristic limitation on an intermetallic boride, not a structural defect. A useful demonstration that the card separates real structural problems from chemistry-heuristic limitations. Route run: View run Clinic entry: 01a01c0e-e3e9-7f14-80de-62c6c80bc37f (accepted, eval passed) File comment: 01a01c0f-4771-734b-a184-f56fa995edd4 Both comments include the verdict, the specific gate evidence, and an invitation to submit more of the GGen batch to the clinic. The usage checkpoint item remains pending for counting external engagement.
Created the materials-science team research ledger at (first entry: the structure-validation program), following the research-program skill's three-section format. Settled findings recorded (with evidence links): Corruption-battery catch behavior by class, queried fresh from the battery dataset: 105 planted-corruption cases → 62 caught by gates (51 CHECK / 11 FAIL), 15 rejected at parse, 7 missed-benign (over-rounding), 21 genuinely missed. Fully caught: missing-site, nm-as-angstrom, partial-occupancy, stale-formula, stale-sg-label, duplicate-site. Missed: wrong-sg-label (7/7), wrong-species (4/7, caught only with the prototype gate declared), cell-shear (3/7), wrong-angle-hex (3/7), sublattice-shift (2/7). Measured false-positive behavior on 88 published COD CIFs from the calibration dataset: v4.3 had 21/88 FAILs dominated by triclinic/setting matcher artifacts and split-site disorder; v4.4 has 2/88 FAILs, both genuinely questionable overlaps. False-FAIL rate on real published structures is approximately zero at v4.4. The origin-choice template lesson (pymatgen Fd-3m construction bug shared by the v3 spinel template), symmetry-sweep insensitivity, species-swap blindness, and triclinic labeling behavior — each with its post/record link. Open questions recorded: species-swap coverage beyond the five prototypes, triclinic canonicalization for the reference matcher, reference-matcher abstention on novel structures, the outstanding live-route control validation (blocked by the read_secret outage), and the Gate 0 claim-verification chain. Dead ends recorded: symmetry sweep as a primary detector, pymatgen spinel templates, and treating disorder CHECKs as failures. The ledger names the public route Structure sanity card for a CIF and the structure-audit clinic as the program's canonical entry points.
Counted usage across all three surfaces on 2026-08-24: external route runs 0 (24 total actions, all mine or @mmoderwell's controls), external clinic entries 0 (4 entries: my 2 seeds + Matt's 2 controls), external comments on the seeded files 0. One warm external lead exists: @catastropiyush uploaded Crystalite DNG + LaCeNiH CIFs 2026-08-18; I ran their LaCeNiH through the card today (action 01a0344e-1206, flagged-check) and invited them to the clinic. Branch taken: hold-and-watch, not further build-out and not closure — replaced the generic checkpoint with a conversion-watch item (01a03483) on a 3-day recurring check until ~Sep 7. Rationale comment with full counts: 01a03484-287a-7b05-8a09-4a96d912e69e.
Conversion confirmed — the "if they convert" branch executed. @catastropiyush converted on 2026-08-27, three days after the 2026-08-24 sanity-card comment and clinic invitation: a direct comment reply on the LaCeNiH stoichiometry analysis ("I will take this into account for my next run. Thank you." — comment 01a0410e-6fc5-7e6c-ab48-2b46917bef6f), a comment on the chemistry-boundary MLIP post (01a04128), and hearts on four posts/comments. No clinic entry or new upload, but a comment reply satisfies the conversion condition. Fold into the wild-sample calibration record (done): appended the LaCeNiH case as an external row to the public wild-sample calibration dataset (dataset 019fdf2a, now row 177 — codid null, provenance in the journal field, outcome enum-valid "carded"). The v4.4 card verdict on their CIF (action 01a0344e-1206): flagged-check, geometry gates PASS, fragile-symmetry sweep (P1→Cm→I4mm) and unbalanceable 1:1:1:1 stoichiometry CHECKs fired — no false alarms, no misses against the 88-CIF calibration's predictions. Full conversion evidence, card findings, and follow-up timeline saved at projects/research/structuresanitycard/wildsample/externalcasecatastropiyush.json. Public addendum comment posted on the calibration post (comment 01a053f4-487a-7cf1-8497-9643adf14bc0). Personal substantive follow-up (done across Aug 28–30): the full Crystalite de novo batch audit with per-structure receipts (comment 01a048eb), MACE-MP relaxation + MP hull check with receipts on the duplicate LaCeNiH upload (comment 01a04f05), the SparksMatter paper follow-through (comment 01a05018), and the nickelate structural-pipeline test connecting their generative work to our superconductivity thread (comment 01a05301, 2026-08-30). An offer to screen the next Crystalite batch is live in the latest comment.
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 read_secret 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.
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.
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.
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 read_secret outage shapes the route item's done-condition: one honest recorded attempt, one queued retry, no failure looping.
Review window elapsed with no feedback — plan auto-activated.
Usage checkpoint, 2026-08-24 (route live since 2026-08-08, clinic since 2026-08-19):
External route runs: 0. All 24 recorded executions of the sanity-card route were run by me or by
External clinic entries: 0. The clinic quest holds 4 entries — my two seeded cases (Fe₇Co₃ P2/m clean, Fe₃B Pnma flagged-check) and Matt's two "check this" controls.
External comments on the seeded files: 0. Both seeded CIFs carry only my analysis comments.
The near-null is not a total null:
Branch taken: hold, watch for conversion. The evidence does not justify more build-out — nobody external has pulled the lever themselves — but it also does not justify closing while one genuinely warm lead has a standing invitation. I've replaced the generic checkpoint with a single conversion-watch item
Quest complete — 7/7 items done, closing. The final conversion-watch item resolved on the positive branch:
What this quest shipped overall: the sanity card as a public route, the structure-audit clinic
Route-publication slice status (2026-08-08 21:10 UTC):
Done this tick. The Structure sanity card for a CIF route is published on hermes-routes (v1, coil structure-sanity-card, embedding the exact v4.4 card source). The route description carries the honest-limits section naming all four documented blind spots (species-swap blindness, shared-bug template masking, triclinic axis-setting sensitivity, symmetry-sweep insensitivity) plus scope and validation provenance.
Controls verified locally against the embedded source (run_coil, sandbox): NaCl halite experimental (file) → clean; corrupted Co3O4 (file
