+- 通过一条逐 Workspace、可中止的队列，串行执行每个源读取／打开／查询／关闭生命周期，因此排队调用只会在轮到自身时读取当前源；不同 Workspace 并行运行。提供方资源释放会中止文件系统与协议工作，等待尚未进入队列的 Workspace 查找结算，再排空所有队列并等待所有服务器结算。
 - 协议 shutdown 失败后，经由进程管理器 seam 终止服务器后代树（POSIX 进程组信号；Windows `taskkill /T /F`）。树终止的投递结果与所有进程组信号一样被就地吸收，不向外抛出（投递与服务器退出存在竞态）；服务器是否完全停稳，由句柄的进程树存活等待确认，而非由这次终止自身的结果确认。
 - 通过 `ctx.subprocess` 解析服务器可执行文件、cwd、进程与协议流；`initialize.processId` 为 `null`，因为另一台机器或 PID 命名空间不得监控 harness 进程。
 - 使用 `ctx.fs` 提供的规范 containment、文件 URI 与稳定有界读取，但不发出 `fs/observed`：只有 LSP 结果对模型可见，因此查询不满足先读后写策略。

Supplied stdin is written and closed; otherwise fd 0 is `/dev/null`.

 - **Offset-based reads** — collect-mode readers return deltas in whole-stream byte coordinates; the service never holds a cursor, so consumer-owned cursors (the bash background read path) and full-stream re-reads coexist, before and after settlement.
 - **Execution-world coordinates** — `cwd` is the host process cwd, `runtimeRoot` is an owner-private temporary directory removed on disposal before any process-cleanup failure is reported, and `resolveExecutable` checks absolute files or searches the scrubbed effective PATH with platform-aware executable extensions.
-- **Terminal-process ownership** — `spawnTerminal` allocates `node-pty`, bridges UTF-8 terminal bytes, inspects and signals the current foreground process group, and cleans descendants before the top-level shell. Each foreground inspection retains exact identities from the rooted tree; Linux also enumerates the POSIX session after its leader exits. A previously observed macOS descendant and any same-session Linux member therefore remain fenced after reparenting, while pid/start identity prevents cleanup from following PID reuse. The higher PTY backend owns prompt readiness, buffers, and model-facing operations.
