Fixed

• Polymarket: Replaced @nevuamarkets/poly-websockets with native WebSocket implementation for watchTrades and watchOrderBook. The third-party package was silently dropping last_trade_price events. Native WebSocket connects directly to wss://ws-subscriptions-clob.polymarket.com/ws/market and receives all event types reliably.
• Polymarket: watchTrades now buffers trades between calls instead of silently discarding them when no promise is waiting. Fixes timeout errors on active markets.
• Kalshi: watchTrades WebSocket handler updated from API v1 field names (yes_price, count) to v2 (yes_price_dollars, count_fp). Fixes silent data corruption where prices and amounts returned as 0.

Documentation

• Watch methods (watchOrderBook, watchOrderBooks, watchAllOrderBooks, watchTrades) moved from OpenAPI spec to dedicated MDX pages with proper WebSocket documentation, per-method parameter tables, response schemas, and SDK code examples.
