Overview

ConnectionController is a read-only observability module for connection health. It classifies errors, records read/connection metrics, and exposes health signals.

Reconnect/dial MUST NOT be triggered through ConnectionController. All reconnect behavior goes exclusively through driver.ConnectionManager (EnsureConnected / ScheduleReconnect).

设计原则:

  1. panic具有最高优先级，直接否决
  2. 允许部分失败（30%成功率即可），适应工业现场不稳定性
  3. 无交互视为最严重失败
