| Stored file | 4,084 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 | f6e2a22e89a92e6be9c553384852632703b9e7e837cf463adeab0961b43fe095 |

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