…nts, deprecations Add batch 6 changes from the Kalshi API changelog (Feb 13-19, 2026): - Deprecate `Market.liquidity` and `Market.liquidity_dollars` (always return 0) - Add `GetBalanceParams` with `subaccount` filter for `GET /portfolio/balance` - Add `settlement_value` to `MarketLifecycleData` for WebSocket determined events - Add 6 historical data endpoints with dedicated response types - Add `HistoricalCandlesticksResponse` with dollar-string-only OHLC types (historical candlesticks use a different schema than live candlesticks) - Add `yes_settlement_value_dollars` to `MveSelectedLeg`
