v0.3.1

中文

新增

• 后台保活（设置 → 行为 → 后台保活，默认开）：切到后台时用前台服务拿住进程，
  连接不再被系统冻结掐断，状态栏会有一条常驻通知。可以随时关掉，关掉立即停服务、
  通知消失。走 SSH shell 页（自己那条连接）时同样生效。
• 断线即自愈：连接一断就自己重拨（先三次，然后每 30 秒一轮、最多四轮），
  期间状态栏文案是「连接断了，正在重连…」；回到前台会先做一次往返校验
  （进程被冻结时 socket 看起来还是开着的）。终端页给了一条回得来的路：
  失败/结束的浮层上有「重试」或「重新打开」，连接恢复后自动重挂。

修复

• 断线之后再也没接上，只能跑去机器上重连：死掉的 SSH 会话被永久当成活的
  （只检查了「有过一个 client」），拨号器也永远没人通知，于是状态停在「已连接」、看板还是旧数据。
  现在传输层自己报告死亡（ConnectionLiveness），死掉的连接不会被交出去，也不会懒重拨。
• 断线被误报成「这台机器上没有找到 herdr」：判断用的是「消息里含哨兵字符串」，
  而哨兵字面量就写在我们自己生成的命令里、报错消息又把整条命令拼了进去 —— 必然命中。
  现在按整行相等判断，错误消息也不再带命令原文（会截断并带上真正的原因）。
• 聊天窗在真机上弹安全输入法、打不了中文：字段设了 enableSuggestions: false，
  而 Android 引擎拿它来实现「不外传学习」的方式是给输入框加上
  TYPE_TEXT_VARIATION_VISIBLE_PASSWORD —— 输入法据此当成密码框。现在保留联想、
  仍然关掉自动更正与标点改写（那两个会悄悄改命令）。真机实测输入类型为
  0x20001（普通多行文本）。
• / 菜单报错时把 8KB 的命令原文甩到屏幕上：现在只给一句人话和失败原因。
• 重连期间看板不再清空：空白等于说「agent 都没了」，而真相是「连接没了」。

English

Added

• Keep-alive in the background (Settings → Behaviour, on by default): a foreground service
  holds the process while the app is away, so the connection is not frozen to death, with a
  persistent notification. It can be turned off at any time — the service stops and the
  notification goes with it. The SSH shell page keeps its own connection alive the same way.
• A dropped connection heals itself: the app re-dials on its own (three quick tries, then up
  to four rounds thirty seconds apart) and says so — "Connection lost — reconnecting…". Coming
  back to the foreground gets a round-trip check first, because a frozen process is not a closed
  socket. The terminal offers a way back from a dead session and re-attaches when the connection
  returns.

Fixed

• After a drop it never reconnected; the only way back was walking to the machine. A dead SSH
  session was handed out forever (the only test was "a client exists"), nothing told the dialler,
  and the status stayed "connected" with a stale board underneath it. The transport now reports
  its own end and a dead one is never reused.
• A dropped link was reported as "herdr is not installed on this machine": the check was a
  substring match on a sentinel that this app writes into its own commands, so any message
  quoting a command matched. It is a line-exact match now, and error messages carry the reason
  instead of the command.
• The chat field brought up a secure keyboard on the phone, with no Chinese input:
  enableSuggestions: false makes Android's engine add
  TYPE_TEXT_VARIATION_VISIBLE_PASSWORD, which keyboards read as a password box. Suggestions
  stay on; autocorrect and the punctuation rewrites stay off, because those corrupt a command.
  Measured on the device: the field's input type is 0x20001, plain multiline text.
• 8 KB of shell command on the screen when a menu failed: one sentence and the reason now.
• The board no longer blanks itself while reconnecting: blank says "the agents are gone"
  when what is gone is the connection.

Installing

Android — adb install -r HerdrPocket-<version>-arm64-v8a.apk
(use armeabi-v7a for a 32-bit device, or the universal APK if you
do not know which one you have).

macOS — open the .dmg and drag the app out. The build is
unsigned, so the first launch needs either a right-click → Open,
or:

xattr -d com.apple.quarantine "/Applications/herdr_pocket.app"
