Scope and limitsThe card reports four biological and chemical evaluations; outcome category: treated as High. Evaluation contents and results are not recorded (hazard rule). 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.

Check notes: Candidate pack passage, model cards compared (research/model-cards). The quotation (30 words) matched the card’s text retrieved for the candidate pack on 2026-11-02 (SHA-256 5fe918b740727770d0571684fd8c168190172649d2b2e8b7ca4cacad23b3e027) and again on 2026-11-03 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: its printed date, as the source records it.
