Returns the full signal registry (143 atomic + 9 composite) with class, horizon, geometry, parameters, 30-day trigger stats, three-axis health grades, walk-forward IS/OOS — plus a meta.service block (universe + walk-forward + macro-regime + OKX/Kraken/Coinbase venues), a meta.by_class strategy-family breakdown, a meta.next recommended 5-step flow, and per-signal _actions with direct URLs to explain / backtest / fork / simulate. One call answers "what is CRYPTYX, what can I buy, and what should I call next".
