nx_buildq_gate.nx

nx_buildq_gate.nx -- the REFEREE for nx_buildq (deploy DL9 bq_dedupe_target, 2026-09-02). Drives the built organ against the REAL nx_store_put on fixture planes under /tmp and asserts: one target enqueued twice is ONE row (by id) and the second add SAYS so; `close` turns a queued row closed in place with its reason; a fired row is left alone; nothing to close is a named NO-ROW with exit 0; an unsafe target is refused; and the pure row finder matches the exact id (BQ-t1 never matches BQ-t10). Every plane assertion re-reads the plane through the store verb, never the organ's receipt. nx_buildq_gate [subject-elf] [store-elf] defaults _build/nx_buildq.sov.elf and _build/nx_store_put.sov.elf license_tier: ORIGINAL. Writes only under /tmp/nx_buildq_gate/. No hw writes.
