- * Gate K线 WebSocket 客户端类,用于连接 Gate 的 WebSocket 接口,
- * 实时获取并处理 K线(candlestick)数据。
- * 同时支持心跳检测、自动重连以及异常恢复机制。
+ * Gate WebSocket 客户端,通过 Java-WebSocket 库连接 Gate.io 的 WebSocket 接口。
+ *
+ * <h3>订阅频道</h3>
+ * <ul>
+ *   <li>{@code futures.candlesticks} — 1m K 线数据(公开频道)</li>
+ *   <li>{@code futures.positions} — 用户仓位更新(私有频道,需 HMAC-SHA512 签名认证)</li>
+ *   <li>{@code futures.ping} — 应用层心跳</li>
+ * </ul>
+ *
+ * <h3>数据流</h3>
+ * <pre>
+ *   onMessage → handleWebSocketMessage → 按 channel 分流:
+ *     futures.pong       → 取消心跳超时
+ *     subscribe/unsubscribe/error → 日志
+ *     futures.candlesticks → processPushDataV2 → GateGridTradeService.onKline()
+ *     futures.positions    → processPositionData  → GateGridTradeService.onPositionUpdate()
+ * </pre>
+ *
+ * <h3>连接管理</h3>
+ * 支持心跳检测、指数退避重连(最多 3 次)、优雅关闭。
