| Upstream commit | 18 Sep 2026 — ab4c43acb2a2 (when this state began to stand in the upstream repository; this archive fetched it at the time above, not then) |
| Stored file | 3,250 bytes — not served (third-party research, archived but not republished here); the hash and timestamp proof below still establish what was published when |
| SHA-256 | fcffa3a220499a3d2ff032d9acde5ab9b815c55650f1632415307b35133f9f04 |

| Prior capture of this target | 3832a73a1680b5b4b903989ca7b220df06b7c803e2cb2be21f4bfd5bfb878e1c (captured 2026-09-12T06:23:17Z) |
Verify: obtain the file from the target address above, then sha256sum it — it must equal the hash above; the .ots proof dates that hash.
