| Stored file | 4,735 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 | 12f4bd91a9673a20cf0a45d2a633bbdc8f11e9974dbe58d5b20dd6d2ef38b9a6 |

Verify: obtain the file from the target address above, then sha256sum it — it must equal the hash above; the .ots proof dates that hash.
