docs(python): make the dsh profile runtime current
Document dsh as the only application launcher across architecture, CLI, SDK, app-boot, Python package, contributor, tutorial, and example references. Explain explicit home selection, profile and patch precedence, persistent external plugin installation, the Node-free runtime path, and the absence of complete-config or ~/.dsh fallbacks.
Record the Python profile-runtime decision and update the active naming, installed-wheel, and SEA packaging notes with precise supersession. Regenerate the configuration catalog and module graph after deleting the carrier, update both reviewed languages and pairing records, and classify the retained standalone Cordis files as lower-level test fixtures rather than launch interfaces.

用于通过 stdio 上按行分隔的 JSON-RPC 驱动 DeepSeek Harness 的 Python 子进程 SDK。安装 `deepseek-harness-sdk` 时,会同时安装当前平台上版本完全相同的 `deepseek-harness-runtime-bin` wheel。

## 启动运行时
|
|
|
|
|
|
|
|
|
|
|
|
Python SDK 没有独立的应用入口。它以 `--profile sdk` 启动内置的 `dsh` CLI;所选 profile 负责 JSON-RPC 服务器、agent 组合、凭据、持久化、工具和关闭流程。
|
|
|
|
|
|
|
|
|
|
|
|
每次启动都必须显式指定 Harness home。请传入 `dsh_home`,或在子进程环境中提供非空的 `DSH_HOME`。SDK 刻意不会发现 `~/.dsh`。

`DeepSeekHarness` 延迟启动运行时,并在调用 `close()` 或退出上下文管理器前复用该进程。首次 profile 握手通过 `initialize_timeout_seconds` 使用独立的 30 秒默认上限;普通轮次在未设置 `request_timeout_seconds` 时仍不设上限。超时诊断会指明所选 profile,并包含保留的运行时诊断。`cwd` 是 agent workspace;`runtime_cwd` 独立选择子进程工作目录。两者都会在启动前转成绝对路径。`provider`、`model`、可选的 `reasoning_effort` 和可选的正整数 `max_tokens` 通过 JSON-RPC 初始化发送。`base_url` 与 `api_key` 会显式覆盖子进程环境中的 `DEEPSEEK_BASE_URL` 与 `DEEPSEEK_API_KEY`。
|
fix(sdk): harden runtime lifecycle and JSON-RPC
Keep DeepSeekHarness.run() reusable, but make ownership of its lazy
runtime process explicit. Document the context-manager/close contract and
update every construction example to use a context manager so repeated runs
remain valid without encouraging leaked subprocesses.
Contain notification predicate failures at the subscription boundary. Remove
only the subscriber whose callback raised, deliver that exception through its
queue, and continue dispatching to healthy subscribers so arbitrary callback
code cannot terminate the shared reader thread or strand later requests.
Enforce one in-flight prompt per server session with an atomic activePrompt
guard. Route overlap through the existing -32603 handler-error response and
clear the guard in finally, preserving parallel prompts across sessions and
sequential reuse without changing JSON-RPC request or notification shapes.
Use StringDecoder for line framing so a UTF-8 code point split across Buffer
chunks is not corrupted. Add a queued-write flush barrier, and make memoized
shutdown await it before disposal and exit while retaining exactly-once
cleanup when shutdown calls race or flushing fails.
Cover callback isolation, same-session exclusion, cross-session concurrency,
split multibyte input, delayed writes, racing shutdown, and flush failure with
deterministic tests.

持久自定义属于 `dsh` profile。使用运行时 wheel 提供的 `dsh` 命令初始化随附的 SDK profile,并安装外部 bundle:
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
export DSH_HOME=/absolute/path/to/isolated-dsh-home
|
|
|
|
|
|
dsh --profile sdk --dump-default-config >/dev/null
|
|
|
|
|
|
dsh plugin --profile sdk add file:/absolute/path/to/my-plugin-bundle
|

`file:` 形式会把本地 bundle 安装到 profile 包树中,使其 peer import 可以到达内置安装后备。Profile manifest 会记录已安装依赖与有序 bundle 层;`$DSH_HOME/profiles/sdk/cordis.patch.yml` 是持久用户 patch。只有管理外部包时,`dsh plugin` 才需要 `pnpm`。运行 SDK 不需要系统 Node.js。

对于单次调用的变更,可传入一个或多个 patch 文件。它们会转成绝对路径,并在 profile 层与 home patch 层之后按顺序传给 CLI:

`profile` 可以选择另一个已存在的 profile,但该组合必须保留 `@deepseek-ai/dsh-sdk-app` 或另一个 `@deepseek-ai/dsh-sdk-jsonrpc-server` 配置项。配置错误会在 CLI 启动或 SDK 初始化时失败;不存在完整配置回退。`dsh_bin` 可以选择另一个 `dsh` 可执行程序,同时保持相同的 profile 语法。任意 argv 替换仅是内部 fake-runtime 测试适配器,不属于公开 API。

`provider` 选择指定 Cordis 组合所注册的提供方路由;`model` 是该适配器解析出的模型 ID。`reasoning_effort` 是该确切路由可选的非空适配器自有标识符;省略时保留模型自身的默认值。`max_tokens` 是一个可选的正整数,用于限制根 agent 及其进程内后代在每次请求中输出的 token 数量;省略该参数时,由提供方的默认行为决定输出上限。缺少适配器、模型不可用或推理强度不受支持时,初始化会在提示词运行前拒绝。压缩摘要继续使用压缩插件单独配置的上限。内置默认组合注册 `deepseek-official`。自定义组合可以挂载 `llm-pi-ai`,在其中配置各提供方专属的凭据和端点,并选择 pi-ai 已安装 catalog 中存在的任意提供方/模型组合。

docs(python): define the standalone minimal profile
Record sdk-minimal as the narrow repository-owned exception to base-first profile composition: callers still launch only dsh and cannot provide an arbitrary Cordis tree, while the shipped bundle may own a complete explicit roster. Cross-link the launcher, profile-bundle, Python-runtime, minimal-agent, snapshot, and telemetry decisions; the supersession audit keeps each older note active because its remaining rationale is independent.
Update the CLI, architecture, Python tutorial/reference, example, runtime-wheel reference, and bundle documentation. The docs distinguish the full sdk profile from sdk-minimal, explain explicit-home/plugin/patch customization, state the minimal permission and persistence choices, and retain the separately packaged web profile and frontend assets for direct dsh use.
Correct dsh-base descriptions to cover base-backed profiles, make SDK startup configuration visible in the generated config catalog, add sdk-minimal to the module graph, and regenerate the base-composition graph. English and Chinese pairs are re-recorded at the exact reviewed contents.

`Session.run()` 的活动区间从提示词被持久 inbox 接收时开始,到整个 agent 下一次进入 idle 时结束,并返回 `RunResult(session_id, final_response, finish_reason, events, notifications)`。`final_response` 是该区间内根会话最后提交的 assistant 文本。`finish_reason` 是最后一个根会话 `turn/end` 的 `kind`,例如 `completed`、`max-tokens` 或 `error`;没有轮次结束时为 `None`。缺少字符串 `data.reason.kind` 的 `turn/end` 违反协议,并会抛出 `SdkProtocolError`。

`HarnessClient` 会在运行时进程的整个生命周期内保留已发现的子 agent 祖先关系。在 `Session.run()` 期间,`RunResult.notifications` 与 `on_notification` 按协议顺序接收根会话和已知后代的通知。`RunResult.events` 只包含根会话事件,因此后代输出不会替换根响应。底层 `session_prompt()` 会立即返回已排队消息的 id;绕过 `Session.run()` 的调用方自行负责后续活动边界。

所选 home 保存 profile、插件与每个 profile 自有的持久资源。完整 `sdk` profile 使用其中的凭据、设置与会话存储;`sdk-minimal` 只使用自己的 JSONL 会话存储。需要隔离这些资源时应使用新的 home;独立工作应使用新的 session id。同时复用 harness 与 session id 会延续持久对话和会话资源。
