Scope and limitsThe card reports prompt-injection red-teaming under a section titled 'External red teaming' (coding, tool use and computer use surfaces) and adversarial testing by crowd workers (Section 1.2). It states that no expert red-teaming sessions were run for CB (Q07). No number of testers or period is given. 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.

The quotation (22 words) matched the card’s text retrieved for the candidate pack on 2026-11-02 (SHA-256 d5dbaab6996c02ad6ff28b032ce5a9c7582e59af09b5d1bc0975cf0235535da9) 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.
