Source details and check notes

Authors: Anthropic
Version: Retrieved for the candidate pack on 2026-11-05 (SHA-256 c358464289e24283fc9d5613d2a676fd8aaba510f1449bcedae01a74d8232ab4) directly from the publisher’s host. Retrieved again on 2026-11-05, after the adjudication, with the same SHA-256; the cross-family check of 2026-11-05 retrieved the same SHA-256. The cross-family check of 2026-11-05 located an Internet Archive capture of 2025-07-17 at the same address; it was not retrieved, so it is not recorded as this source's archive copy.

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-3). The quotation (6 words) matched the card’s text retrieved for the candidate pack on 2026-11-05 (SHA-256 c358464289e24283fc9d5613d2a676fd8aaba510f1449bcedae01a74d8232ab4) and again on 2026-11-05, 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. Edition identified by link annotation: the hyperlink on these words points to https://www-cdn.anthropic.com/872c653b2d0501d6ab44cf87f43e1dc4853e4d37.pdf, whose cover reads 'Version 2.2' and 'Effective May 14, 2025'. The quotation check cannot verify a link; the drafting pass read its target on 2026-11-05, and the cross-family check of 2026-11-05 read and confirmed it (maintainer decision 4a of 2026-11-03). A cross-family machine check (2026-11-05, item 4) checked this passage’s cell and agreed with the pack. The pack was prepared by a model of the GPT family (Codex) and checked by a Claude model. No human editorial review.
