Scope and limitsParticipant's retrospective statement; the 1965 date is claimed, not attested by a 1965 text. Buchanan and Shortliffe (1984) say DENDRAL was started 'in the mid-1960s' by Lederberg and Feigenbaum.

Check notes: Candidate pack passage, Kinds of AI and technical history (research/technical-history). The quotation (22 words) matched the text retrieved for the candidate pack on 2026-10-29. 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 (31 October 2026, item 110) re-read the record’s sources and found that they support what the record states. Its point that the 1965 date is labelled as claimed by the 1977 account was applied at admission. 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. Dated by the text that states it, 1977. The statement reports 1965: Year claimed for the work by Feigenbaum’s 1977 account; not attested by a 1965 text read here.
