Scope and limitsThe copy read prints two revision dates (June 20 and October 22, 2024) and no issue date of its own. Anthropic's index gives the month March 2024, a page not yet checked as a source; until it is, the row is dated by the later update line, as a revision (maintainer decision 3a). Search for the rest of the criterion: Cover and abstract (PDF p. 1), the page footers, and term search across PDF pp. 1–42. Terms searched: “2024”, “March”, “Update”, “published”, “dated”. Passages read and not counted: Figure 16 caption, PDF p. 23: 'This plot was updated on June 20, 2024' dates a figure correction, not the card. Stated, partly: the passage has what the question’s criterion asks for, in a weaker or narrower form than the criterion’s own words. 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.

Version: Retrieved for the candidate pack on 2026-11-04 (SHA-256 88ae851f53c3034d436816164ce49a876b333fa9b550fb7ef29838182b59ba7d) directly from the publisher’s host. Retrieved again on 2026-11-03 with the same SHA-256. The copy read is the revision of October 22, 2024; its PDF pages 43 to 63 hold the two Claude 3.5 addenda, which are separate cards and were not read for this row. The cross-family check of 2026-11-04 retrieved the original 42-page expression from an Internet Archive capture of 2024-03-04 at an earlier address (https://www-cdn.anthropic.com/de8ba9b01c9ab7cbabf5c33b80b7bbc618857627/Model_Card_Claude_3.pdf); it is not recorded as this source's archive copy because its bytes are those of another expression.

Check notes: Candidate pack passage, model cards compared (research/model-cards-2). The quotation (13 words) matched the card’s text retrieved for the candidate pack on 2026-11-04 (SHA-256 88ae851f53c3034d436816164ce49a876b333fa9b550fb7ef29838182b59ba7d) 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. A cross-family machine check (2026-11-04, item 41) checked this passage’s cell and agreed with the pack. 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.
