Scope and limitsThe report prints the date June 12, 2026, without a kind. arXiv's margin stamp on PDF p. 1 reads '14 May 2026', which does not agree with the printed date or with the identifier 2606.12429; both are recorded as read, and neither is the card's own statement of publication. Meta’s own copies were retrieved in the cross-family check of 2026-11-04 (not here: ai.meta.com answered HTTP 400 and web.archive.org refused connections): an Internet Archive capture of 2026-04-14 holds an earlier 158-page expression that prints April 14, 2026, and the live copy prints May 26, 2026. Under maintainer decision 3a the row is dated by that earliest located copy, 2026-04-14; the arXiv copy read here is a later expression. The arXiv stamp of 14 May is the submission date, corroborated by the repository history. What the card states, quoted from the expression read. A card is the developer’s own account: not evidence that an evaluation was run as described, that a safeguard works, or that a finding is independent.

Retrieved again on 2026-11-03 with the same SHA-256. Meta's own address for the report answered HTTP 400 to the candidate pack, so the report was read on arXiv. The copy read prints 'Date: June 12, 2026'; arXiv's margin stamp on its first page reads 14 May 2026, the submission date.

Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, model cards compared (research/model-cards-2). The quotation (4 words) matched the card’s text retrieved for the candidate pack on 2026-11-04 (SHA-256 977d071052e3f5dc267e1022671babf6a7967111f9bf2ad84e88b6419b405e61) and again on 2026-11-04, after the adjudication, in a fresh retrieval with the same SHA-256. Matching ignored differences of whitespace, case, quotation marks, dashes, PDF line-break hyphens and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.

Status and meaning

Editorial status. Machine-checked. Machines found this record and checked it against its sources; no person accepted it individually. Each evidence record above shows how it was checked.

Relation. An exact framework edition, or another document with an exact expression, states one provision: a capability threshold or risk level and its trigger, a required safeguard or action, a decision authority (who decides, recommends, can overrule or is informed), a stated exception, or another statement of its content, such as a licence term or a prospectus statement. The passage records what the document says, not implementation, compliance or effectiveness. Provisions with the same key align across editions of one family.

Date. Dated as the card read is dated: the date of its revision, as the source records it.
