ABET — Book Master Key (the Rosetta Stone — every book's every feature & factor)

For each book: how it names and shapes every bet — the archetype, the odds format, the event-name order, the line dialect, the market nomenclature (raw label → canonical), the team-name variants it emits, the states it exposes, the sports its scraper serves, and the exact evidence path into its raw for the moneyline. This is the decoder that lets any book's bets be married to any other's. Auto-generated every pull from live raw by crossbook/build_master_key_v1.py — it cannot drift from the scrapers.
