Reuse: No open redistribution licence asserted. Bibliographic metadata and brief attributed paraphrases or excerpts only. Source roles are relative to each claim.
Check notes: Candidate pack passage, lab genealogy (research/lab-genealogy). The paraphrase’s verbatim anchor “Former GPT-3 and API Engineer at OpenAI” matched the retrieved text on 2026-10-15 and again in a fresh retrieval the same day. Read directly from the publisher. Matching ignored differences of whitespace, case, quotation marks, apostrophes, dashes and Unicode compatibility forms, so the source’s typography can differ. The paraphrase is Selekoa’s; only the anchor is the source’s wording. A cross-family machine check (2026-10-16/17) re-read the record’s sources and agreed with the record. No human editorial review.
