初始提交：terminalX 可运行态（M0/M1/M1.5 已真机验证）
- M0: libghostty SSH 终端（渲染/输入/连接）+ 白屏修复(OutputGate) + 会话状态机/自动重连 - M1: tsnet 用户态组网 + SSH-over-tsnet(fd 桥)，shell 级真机验证；R5(Go+gvisor+C+++Swift 同进程) retire - M1.5: tmux -CC 原生 tab（MVP） - 结构: packages/(TXCore·TXTransport), apps/TerminalX, vendor/(libghostty-spm/libssh2/mbedtls/tsnet-bridge), artifacts/ - 文档: CLAUDE.md + docs/HANDOFF.md（新会话入口） - 环境: 认证代理→依赖 vendor 本地化；Go 在 ~/.local/go；仅模拟器/未签名 - 待续: M2 mosh, tmux 多 pane, M4 安全(host key/SE) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
