被控端 - 修复 MTU 问题：夹 MSS + 路径 MTU 探测（公网可用率 48% -> 100%） - 复用 HTTP 连接（免掉每次新建 TLS 的 30% 握手失败） - 每分钟回头找局域网，自动切回快 400 倍的路径 - 画面心跳帧：静止时省流量，客户端仍知道流是活的 - 锁屏时给出可操作的提示 手表端 - 内置 GTS Root R4 / GlobalSign Root CA，修 SSLHandshakeException - 连接错误翻译成人话（证书/时间/解析/超时分别提示） - 经中转连上后用服务器报的地址刷新已配对记录 - 新增局域网连接页面、服务器延迟检测 服务器端 - 支持 chunked 请求体（修每 16 秒一次的连接错乱与大面积 502） - 网络调优脚本 net-tune.sh（开机自动应用） - 管理页：批量删除、网络体检、下载区 - 隧道改 HTTP/2 + 双连接 文档 - 许可协议 / 安装前必读 / 安装后须知（作者：小麦子）

"""查我改的 _post 到底发出去什么坏请求。
|
||
|
||
线索：隧道日志每 16 秒（= 轮询间隔）刷：
|
||
Unsolicited response received on idle HTTP channel
|
||
Error code: 400 Message: Bad request syntax ('0').
|
||
"Bad request syntax ('0')" 很像 **chunked 编码的结尾**（0\r\n\r\n）
|
||
被当成请求行了 —— 也就是 http.client 用了 Transfer-Encoding: chunked，
|
||
而 Python 的 BaseHTTPRequestHandler 默认**不解析 chunked 请求体**。
|
||
|
||
这个测试：
|
||
1. 起本地 relay
|
||
2. 用 RelayLink._post 连打几次
|
||
3. 把 relay 收到的原始请求行/头打出来
