Venue-coverage census — every head-to-head competition on the venues and its aggregation status (v2)

The full Kalshi head-to-head universe (every match-winner series, wired or not) with per-competition status: aggregated (paired live), pending (wired, awaiting a counterpart or confirmation), quiet (wired, offseason), kalshi_only (listed there, no pairing wired), dormant (series exists, nothing open). poly_unpaired carries the sport-level Polymarket surplus. Written hourly by the matcher pass (discovery inversion, 2026-07-04).
