| Stored file | 3,914 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 | 45c7632264684f61b8d975293720a3f253fdb1b3b06b5f1cc44f7c82049928b9 |

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