nx_compare_feed_gate.nx

nx_compare_feed_gate.nx -- teeth for nx_compare_feed_lib (ecosystem EC47, 2026-09-16): the /compare daily feed built from a FIXTURE root under /tmp/nx_compare_feed_gate/ (the gate-fixture law: scratch in /tmp/<gate>/, created at setup, never a production shard). Three boards are listed: alpha (three players, two spine days inside the window and one outside it, a malformed spine row, two log rows on different days, one carrying markup that must be escaped), beta (one spine day -> "first day on the map", no plan file), gamma (listed, no spine -> no item). Today is pinned to day 20712 (2026-09-16) so every date in the expectations is a known answer, not the clock. Every count the lib publishes is asserted against the fixture it was built from, the quadrant words are the map's own, and the negative control is an empty list that must still yield a well-formed, item-free feed.
