Awaiting operator and domain-expert review; publication of this revision implies neither.

Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

createdAt previously read 2026-09-03T22:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T04:19:37Z on 2026-08-27; evidence: first appears in commit d28da6764c, committed 2026-08-27T04:19:37Z.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
