Attribution: Lucas Beyer, “Lucas Beyer post on X, 26 June 2025”, 2025-06-26.
Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, lab genealogy 2 (research/lab-genealogy-2). The paraphrase’s verbatim anchor “joining Meta” matched the retrieved text on 2026-10-29 and again in a fresh retrieval. Read through X’s own syndication endpoint for the post’s text, which truncates long notes. 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 (2026-10-31, item L073) re-read the record’s sources. No human editorial review.
