Source details and check notes

Authors: EvolutionaryScale
Version: Retrieved for the candidate pack on 2026-10-30 (SHA-256 ba2099c4859e8a93fe926a43096fbf312f486e94352167322739329a812de489). Post dated 6.25.24 with a January 2025 update note, page as served on 2026-10-30. The page as served in 2026 carries a Tom Sercu byline that the capture of 26 June 2024 lacks; the cross-family check of 2026-10-30 found the date 25 June 2024 in that capture, without the byline, so the author is given as the company. Its wording can change; earlier wording is not authenticated.

Check notes: Candidate pack passage, AI in biology (research/ai-in-biology). The quotation (31 words) matched the text retrieved for the candidate pack on 2026-10-30. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. 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. Date of the announcement. The quoted wording is attested only from the page as served on 2026-10-30; the cross-family check did not report it in the capture of 26 June 2024.
