 - **⚠️ 无历史缓冲**：serial-mcp-server 的 `read` 只能读调用后的字节。抓开机日志必须走 `run_boot_test.ps1`（先采集等 first-byte → 再烧录触发）。
 - **⚠️ EOF 陷阱**：COM 刚释放立即重开会报 `UnexpectedEof`（tokio-serial 读 0 字节）。`serial_capture.ps1` 内置自动重试；别裸跑 CLI capture。
 - **参数**：`IdleTimeoutMs` 需 ≥ boot 自然静默间隙（本机 ~3-4s，用 8000）；`InitialTimeoutMs` 需覆盖编译+烧录耗时（用 90000）。
