/**
 * scripts/propline-audit.js (Session 56) — the data-source audit.
 *
 * Inventories what our providers CAN send (from code) and what the FREE
 * settled-result APIs (MLB Stats, ESPN) actually return, so we can map every
 * prop stat_type to its box-score field. PropLine live fetch runs only when
 * PROPLINE_API_KEY_* are present (they aren't in dev) — otherwise we report the
 * authoritative code inventory (MARKETS × MARKET_MAP).
 *
 * Usage: node scripts/propline-audit.js   (writes JSON to stdout)
