nx_cell_lib.nx -- ORGANISATION AND PLACE CELLS AS ROWS (shared lib, 2026-08-24). A CELL is one node of the hierarchy a feedback surface rolls up through: a congregation, an agency, a nonprofit program (organisation cells) or a locality, region, nation (place cells). One record kind, one key family, one parent pointer -- the tenant row every multi-organisation surface needs and none had (absence proven 2026-08-24: no tenant lib in 23,167 sources). Composes the survey engine's store discipline: canon-encoded records on the append-only seg_store, latest version wins, history kept. key "cell:<id>" fields type=cell id kind name parent denom usec id a-z 0-9 only, 1..CEL_ID_MAX -- no dash, so "<instrument>-<cell>" survey ids split without ambiguity; CEL_ID_MAX is DERIVED: the engine's survey-id bound is 40 (se_id_ok) and the instrument name is bounded at CEL_INST_MAX, so CEL_INST_MAX + 1 + CEL_ID_MAX == 40. kind must appear in the caller-supplied comma list (conf data, never a literal here) parent another cell id that EXISTS, or "-" for a root; an unknown parent REFUSES by name denom declared denominator (roster size, population) for post-stratification; 0 = undeclared license_tier: ORIGINAL
