Second wave of community PR triage. Each of these was reworked before landing — the original branches carried stale reverts, file-encoding corruption, or compile errors, so only the intended net change was applied on top of current main, then re-verified. All Core (816), Python SDK (267), and TypeScript SDK (93) tests pass. Minor bump for the new opt-in Router and WebSocket capabilities.

Added

• feat(sdk): Router.sql(query) (#1129). Both SDKs gain a Router.sql() / Router.sql() method that POSTs a query to the server's existing /v0/sql endpoint (read-only ClickHouse, error-scrubbed) with the SDK's normal auth headers, returning a typed SqlResult (SqlMeta/SqlColumn) exported from each package root. The original PR's UTF-16 file corruption and unrelated reverts were dropped.
• feat(sdk): cross-venue Router.fetchOrderBook(outcomeId) (#1670). Both SDKs expose a Router-level order-book fetch that routes through the existing core Router.fetchOrderBook surface and returns a single merged OrderBook. Reimplemented as a proper Router class method (the original defined it at module level, which gutted the Python Router class).
• feat(sdk): expose WebSocket configuration for Polymarket and Kalshi (#1126). A websocket options object (reconnect interval, max reconnect attempts, ping interval, connect timeout) is threaded through the SDK exchange constructors into the WebSocket clients in both SDKs. Reconciled with the [#1659] handshake-timeout/retry work already on main, and the fast default reconnect backoff is preserved (no 5s-default regression).

Fixed

• fix(baozi): correct program error-code mappings (#1118). Remap 6018/6040/6020/6041 → 6013/6014/6023/6024 to match the current on-chain IDL. Applied without the stale hosted-trading reverts the original branch carried.
• fix(limitless): paginate all markets (#1119). Replace fixed-page parallel fetching with sequential pagination driven by totalMarketsCount (with a 50-page safety cap) plus a token-filter over-fetch factor, so large limit requests return the full set. Applied without the stale reverts.
• fix(ts-sdk): align MatchResult / PriceComparison nullable fields (#1578). Widen reasoning, bestBid, bestAsk to T | null to match openapi.yaml (nullable: true). The half-wired parity CI from that PR was intentionally not included.

Not merged

• #1614 (feat(probable)) was rejected: it exposed session credentials (apiKey/apiSecret/passphrase) over an HTTP endpoint keyed by a public wallet address. Held out pending a fix that stops returning secrets over the server surface.
• #1419 (replace any with proper types) was superseded: the remaining any usages are raw wire-JSON in converter helpers with no genuine importable type to substitute; the public Router signatures are already typed.
