| Stored file | 3,984 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 | 5715918bf3d6b73163a5f0baab1d3ab998ac10e08c3d32c593fdc9e5d7a301b7 |

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