Scope and limitsThe card lists attempts to manipulate users toward certain views among the behaviours its alignment assessment tested for; no outcome specific to manipulation or persuasion was found. The overall alignment conclusions are recorded in Q11. Search for the rest of the criterion: Sections 3.5, 6.1–6.2 and term search across the card. Terms searched: “persua”, “manipulat”, “influence”, “sway”, “political”. Passages read and not counted: Section 3.5.1 'Political bias', PDF pp. 43–45: Even-handedness evaluation measures bias in responses, not persuasive or manipulative capability. 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.

Check notes: Candidate pack passage, model cards compared (research/model-cards). The quotation (13 words) matched the card’s text retrieved for the candidate pack on 2026-11-02 (SHA-256 33be92efcb58f901d9d2c17e61bf277afbd514a1ac70a642f21e918c21ca25a8) 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. A cross-family machine check (2026-11-03, item 10) 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.
