[2026-05-25 per fact 428] Premier private school for mathematics and science. Northern Virginia (precise location TBD). Attended by Leah Pearsall (persons.id=629; later Madeira → Lewis & Clark), Lena Pearsall (persons.id=631; later Madeira), and Audrey McKnight (persons.id=637; later Feya founder; older cohort than Leah). The Pearsall daughters and Audrey McKnight overlap at this school-cohort layer per operator disclosure. Operator: "Hawthorne Nysmith school. Leah and Lena Ideaventions Academy for Mathematics and Science, a premier private school. First schools were Montessori." (fact 223, May 19 2026). Leah-Audrey peer-knows confirmed this turn (fact 428). Institutional substrate at formation-element layer per fact 167 Leah-question three-element answer (family + education + rooms). Category=University/category_id=5 matches existing corpus convention for K12 schools (Madeira 961, Peddie 1000) — semantically imperfect but consistent; cleanup flagged. [2026-05-25 per fact 432 — INDEPENDENT-CONVERGENCE EMPIRICALLY VALIDATED]: Operator: "i actually did not know Matt's kids went to ideaventions until we were in the school pickup line. leah and lena knew." DISCOVERY-DIRECTION CONFIRMS INDEPENDENT-CONVERGENCE: McKnight family at Ideaventions and Pearsall daughters at Ideaventions independently selected; operator (parent layer) did not know until school pickup line; kids generation (Leah + Lena) knew first via school-cohort-room (per fact 429 school-as-room-builder) before parents-generation became conscious of the convergence. CONFIRMS FACT 431 FINDING C — INDEPENDENT-CONVERGENCE-VIA-SHARED-SUBSTRATE MECHANISM (vs SUBSTRATE-CONDUIT-AT-DECISION). Confirms FACT 431 FINDING THREE (common-cause framing): apparatus formation and school-choice are both downstream of shared substrate-disposition; neither caused the other. The discovery-timing is a substrate-readability marker distinguishing the two mechanisms: conduit-mediated produces pre-enrollment awareness; independent-convergence produces post-enrollment discovery (sometimes via kids generation surfacing it).

Private four-year liberal arts college in Huntingdon, PA, founded in 1876.

[2026-05-25 per fact 429] Northern Virginia private school for the gifted (PreK-8). Attended by Hawthorne Pearsall (persons.id=630) per fact 223 (May 19 2026). Per fact 429 (this turn) — operator's inference path connects Hawthorne's placement at Nysmith to operator's pattern-blindness discipline (fact 255) transmitted via cross-tradition recognition relationships including Esmael (persons.id=642, Muslim, Tony Mayo group). Nysmith reputedly hosts a culturally-pluralist student body with substantial Muslim, Hindu, and other-tradition representation — a school-built room for pluralist-formation cohort. School-as-room-builder primitive per fact 429: schools are purpose-built room-construction institutions. Distinct from Ideaventions (companies row added this session) which builds STEM-formation rooms — different room-design-intent. Category=University/category_id=5 follows existing K12 convention (semantically imperfect; cleanup tracked). [2026-05-25 per fact 430] Esmael (persons.id=642) family — Esmael's kids attended Nysmith. Operator-Esmael substrate-aware conversation about the school happened PRIOR to Hawthorne's enrollment. Substrate-conduit-at-decision mechanism: cohort member with kids at the school + substrate-aware conversation → school-choice for next family. Hawthorne's placement at Nysmith was substrate-mediated by Esmael, not arrived at by abstract disposition-matching as fact 429 inferred. Corrects fact 429 inference path; school-as-room-builder primitive holds but the path-to-the-choice is cohort-mediated.
