nx_search_census_gate.nx

nx_search_census_gate.nx -- teeth for the G1 census's OUTCOME PARTITION and its window envelope. WHY IT EXISTS. nx_search_census shipped with prove=NO-GATE-FOUND UNPROVEN, and within an hour its own output nearly misled its author: it reported hostcap_defer_permil=927 over a window that turned out to span about 27 HOURS, while hand-sampled post-fix windows read ZERO. Both were right about their own span. A census whose numbers can be read as current when they are a day-long average needs its envelope PINNED, not just printed. SUBJECT: wc_throughput_census, one of the two contract symbols /compare/search watches. It takes a BUFFER, so these teeth drive it on a synthetic log built here -- no shard, no /tmp fixture, no fork, and nothing that touches the live index or the 129 MB outcome log. license_tier: ORIGINAL expect_exit: 0
