| Upstream commit | 18 Sep 2026 — ab4c43acb2a2 (when this state began to stand in the upstream repository; this archive fetched it at the time above, not then) |
| Stored file | 20,413 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 | dba85c97fd02806b263abab5001dd4a484905773030ab12b1235369b5c59ccf9 |

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