nx_cms_schedule_exceed_gate.nx

nx_cms_schedule_exceed_gate.nx -- measured head-to-head EXCEED for scheduled-publishing (schedule-determinism axis). OURS = the shipped nx_cron core (tick-driven, fire-once, catch-up-once, NOT traffic-gated) -- measured live here by registering jobs + ticking + reading fired_count. INCUMBENT = the documented wp-cron model: a "pseudo-cron" fired by page traffic, whose two well-documented failure modes are (a) NO-TRAFFIC -> a due job never runs, and (b) concurrency -> the same job double-fires. Ground truth per scenario = fire EXACTLY once iff due. The nx_cms_exceed referee computes the verdict + cannot false-green. Records a CMSEXCEED AHEAD line only if measured-clean. HONEST counter-axis (named): wp-cron needs NO separate scheduler daemon (zero-ops); our determinism costs a running tick source. license_tier: ORIGINAL
