core.md read as a type grab-bag: LLM wire vocabulary up front, the agent/loop story buried, and no correspondence to packages/core. It now opens on the packages/core control spine — the package-by-package loop map with a Page column into session/system-prompt/tools/scope — and keeps only what the spine group declares plus the repo-wide patterns: the Agent handle with its delivery/cancellation/interception contracts, the SessionEvent envelope, branded ids, the …Map pattern. The conversation vocabulary (Message/ContentBlock, the model request, adapters — 17 type-equiv blocks) moves to llm-streaming.md, which now declares packages/llm end-to-end; the duplicate ContentBlockMap paste near its seam section folds into the moved section, and the manifest, LINK_MAP, README table rows, website label (Core data structures → Core), and inbound anchors follow. Every packages/<group>/README pair is now a thin front door in one shape: a why-first intro (bash's seam-pattern-first paragraph rewritten as 'shell execution for the agent'), the package table, and a closing pointer to the owning docs/subsystems page — the bash-style table stays the load-bearing middle. Load-bearing trailing paragraphs relocate rather than vanish: the fs no-timeout rationale becomes a filesystem.md section (both languages), session's four sectioned tables merge into one 12-row table, examples' legacy-bin H2 collapses to a pointer at jsonrpc-demo's README, and design rationale that already lives in an Agent Note or subsystem page is now linked instead of restated. All 40 pair records re-recorded.

# pty/：持久 PTY 能力家族
|
||
|
||
[English](README.md) | 中文
|
||
|
||
`PTY` 的全称是 **Pseudo-Terminal（伪终端）**。这项能力提供持久且限定所有者范围的终端会话，适用于需要跨工具调用保留状态或使用交互式 stdin 的工作流。PTY 是单次 bash 与文件系统工具的补充，不会取代后两者更严格的逐操作契约。
|
||
|
||
| 包 | 职责 | ctx 键 |
|
||
|---|---|---|
|
||
| [`pty`](pty/README.md)（`@deepseek-ai/dsh-pty`） | 后端注册表、品牌化 id、精确的 Agent 所有权、会话操作与等待完成的清理 | `ctx.pty` |
|
||
| `pty-local`（`@deepseek-ai/dsh-pty-local`） | `ctx.subprocess.spawnTerminal` 之上的 shell 后端：就绪检测、有界终端状态、沙箱策略与会话操作 | 注册到 `ctx.pty` |
|
||
| `tool-pty`（`@deepseek-ai/dsh-tool-pty`） | 6 个面向模型的工具，并为后台发送集成通用任务 | 注册到 `ctx.tools` |
|
||
|
||
设计与暂缓边界记录在[持久 PTY Agent Note](../../.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.md) 中。

子系统参考——id、后端/会话契约、发送就绪、有界读取——见 [docs/subsystems/pty.md](../../docs/subsystems/pty.md)；设计与延后边界见[持久 PTY Agent Note](../../.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.md)。
