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 2026-08-27T17:00:00Z. 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 2026-08-26T23:41:56Z on 2026-08-27; evidence: first appears in commit ddeb6bde77, committed 2026-08-26T23:41:56Z.

  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
