| Stored file | 5,290 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 | 5ff4215efaf00562aa9363ba5de33d958a0d59a52e3f397165c32fc47add9a48 |

| Prior capture of this target | 25209313cd955b341bf1aeafd9fbb68d897c06e8ce951a90acc33b054fbe0d68 (captured 2026-08-29T18:57:26Z) |
Verify: obtain the file from the target address above, then sha256sum it — it must equal the hash above; the .ots proof dates that hash.
