| 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 | 4d757450f2f2c94e5f723a652adb2820221924880bf7f0ba3a16ac4af89c73f6 |

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