A **bundle** is an npm package declaring `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }`; the two manifest kinds live under distinct `dsh.profile` / `dsh.bundle` keys so a package.json states which role it plays. The tree composes over an empty root by applying each bundle's patch in `dsh.profile.bundles` order, then the user layer, then `--patch` overlays, then flag patches — one `applyEntryPatches` call, identical for boot, flag derivation, and `--dump-config`.

+# Agent Note: `dsh run` owns one-shot headless execution
+
+Status: implemented
+
+English | [中文](2026-08-08-dsh-run-headless-command.zh.md)
+
+## Problem
+
+The product launcher attached optional task text to its generic profile boot: `dsh --profile headless "task"`. That made one argv shape mean either a long-lived profile or a one-shot run according to a row discovered only after composition. The parser's `ProfileInvocation` carried optional task state, help presented a profile implementation detail as the user command, and a custom profile could accept a task only through the same overloaded root.
+
+The former `dsh -p` spelling was already absent from the parser, so restoring it or detecting it specially would add compatibility machinery to a pre-release interface. A separate application-file proposal also used the `run` verb, leaving two incompatible owners for one top-level command.
+
+## Decision
+
+One-shot execution owns an explicit grammar:
+
+```text
+dsh run [--profile <name>] [--patch <path>...] <task...>
+```
+
+`--profile` defaults to `headless` and remains available for custom one-shot compositions. `--patch` is repeatable and occupies the existing overlay layer. Commander joins the variadic task arguments with spaces and rejects a missing or blank task before boot.
+
+The [profile plugin bundle decision](../architecture/2026-08-05-profile-plugin-bundles.md) owns the composition selected by this grammar.
+
+`RunInvocation` is a separate `DshInvocation` member. The generic profile invocation no longer carries task text, and its root command accepts no positional arguments. Both dispatch paths call the existing deep `runProfile` module: `profile` omits `task`, while `run` supplies it. There is no shallow `run.ts` forwarding module and no alias, warning, or custom detector for former spellings; they fail through the ordinary Commander grammar. A one-shot profile without `headless-runner` still fails through the existing composed-row check, while booting a profile that contains that row without a task points to `dsh run --profile <name> "<task>"`.
+
+The `run` verb belongs to one-shot task execution. Launching an application file must choose another command name; two top-level meanings selected by positional shape would recreate the ambiguity this command removes.
+
+The runner's user-visible contract stays the same: a fresh persisted session, browser observation URL on stderr, final assistant text on stdout, completed/non-completed exit mapping, and bounded signal shutdown. The product-level keyless acceptance exposed that the in-process mux consumer could lag the same-process `agent/status: idle` notification and derive output before reading the final frames. The idle notification now captures the authoritative final session sequence, and the runner waits until the ordered mux reaches that boundary (or the stream ends) before deriving text and exit reason. This enforces the existing idle-to-idle contract without adding a wire field or a timing delay.
+
+## Alternatives considered
+
+- **Keep task text on `dsh --profile`.** Rejected because profile boot and one-shot execution remain one grammar whose meaning depends on a late composition check.
+- **Preserve `dsh -p` or the positional profile form as aliases.** Rejected under the pre-release stance: compatibility branches would outlive the interface they were meant to retire.
+- **Make `--profile headless` mandatory under `run`.** Rejected because the shipped one-shot surface should have the shortest canonical spelling, while optional `--profile` preserves plugin-defined one-shot compositions.
+- **Give `dsh run` to application-file launch and choose another headless verb.** Rejected because `run` describes executing a task through the harness; application-file ownership would make the product's primary one-shot command less direct and collide with custom one-shot profiles.
+- **Add `apps/cli/src/run.ts`.** Rejected because it would only forward to `runProfile`, splitting command ownership without hiding any complexity.
+
+## Consequences
+
+This is an intentional breaking CLI change. Documentation, help, parser tests, built-bin acceptance, PTY shutdown coverage, and the assembled keyless snapshot use `dsh run`. Existing custom one-shot profiles keep working through `--profile`; long-lived profiles and config dumps retain their existing root grammar. The competing application-file command must be renamed and rebased separately rather than sharing or overloading `run`.

+# Agent Note: `dsh run` 负责一次性 headless 执行
+
+Status: implemented
+
+[English](2026-08-08-dsh-run-headless-command.md) | 中文
+
+## 问题
+
+产品启动器过去把可选任务文本挂在通用 profile 启动命令上：`dsh --profile headless "task"`。于是，同一种 argv 形态会表示常驻 profile 或一次性运行，具体含义取决于组合完成后才发现的配置行。解析器的 `ProfileInvocation` 携带可选任务状态，帮助信息把 profile 的实现细节呈现为用户命令，自定义 profile 也只能通过同一个过载的根命令接收任务。
+
+解析器中已经没有原来的 `dsh -p` 写法，因此恢复该写法或加入特殊检测，会给预发布接口增加兼容机制。另一个应用文件提案也使用 `run` 动词，使同一个顶层命令同时归属两个互不兼容的功能。
+
+## 决策
+
+一次性执行采用明确语法：
+
+```text
+dsh run [--profile <name>] [--patch <path>...] <task...>
+```
+
+`--profile` 默认为 `headless`，同时保留对自定义一次性组合的支持。`--patch` 可重复使用，并沿用既有 overlay 层的位置。Commander 用空格拼接可变数量的任务参数，并在启动前拒绝缺失或空白任务。
+
+[profile 插件组合包决策](../architecture/2026-08-05-profile-plugin-bundles.md)负责该语法所选择的组合。
+
+`RunInvocation` 是单独的 `DshInvocation` 成员。通用 profile 调用不再携带任务文本，其根命令也不接受位置参数。两条分派路径都调用已有的深层 `runProfile` 模块：`profile` 省略 `task`，`run` 则提供该字段。实现中没有只负责转发的浅层 `run.ts` 模块，也没有面向旧写法的别名、警告或自定义检测器；旧写法会按普通 Commander 语法失败。缺少 `headless-runner` 的一次性 profile 仍会触发既有的组合行检查；如果启动的 profile 包含该行却未提供任务，错误会指向 `dsh run --profile <name> "<task>"`。
+
+`run` 动词只负责一次性任务执行。应用文件启动必须选择其他命令名；如果让两个顶层含义由位置参数形态决定，就会重新引入本命令消除的歧义。
+
+运行器面向用户的契约保持不变：创建新的持久化会话，在 stderr 打印浏览器观察 URL，在 stdout 打印最终 assistant 文本，将完成／未完成映射为退出状态，并执行有界的信号关闭。产品级无密钥验收用例发现，进程内 mux 消费方可能落后于同进程的 `agent/status: idle` 通知，在读到最终帧之前就生成输出。idle 通知现在会捕获权威的会话最终事件序号，运行器则等待有序 mux 到达该边界（或流结束），再生成文本和退出原因。这一机制在不增加 wire 字段或定时延迟的前提下，落实了既有的 idle-to-idle 契约。
+
+## 考虑过的替代方案
+
+- **把任务文本保留在 `dsh --profile` 上。** 不予采纳：profile 启动和一次性执行仍共用同一套语法，其含义取决于较晚发生的组合检查。
+- **保留 `dsh -p` 或位置参数 profile 形式作为别名。** 不予采纳：根据预发布立场，这些兼容分支会比本应退役的接口存续更久。
+- **要求在 `run` 下必须指定 `--profile headless`。** 不予采纳：已交付的一次性接口应采用最短的规范写法，同时用可选的 `--profile` 保留插件定义的一次性组合。
+- **把 `dsh run` 交给应用文件启动，并为 headless 选择另一个动词。** 不予采纳：`run` 描述的是通过 harness 执行任务；若归应用文件所有，产品的主要一次性命令会更不直接，并与自定义一次性 profile 冲突。
+- **新增 `apps/cli/src/run.ts`。** 不予采纳：它只会转发到 `runProfile`，拆分命令归属，却没有隐藏任何复杂度。
+
+## 后果
+
+这是一次有意为之的 CLI（命令行界面）破坏性变更。文档、帮助信息、解析器测试、构建后二进制验收、PTY 关闭覆盖和组装应用的无密钥快照都使用 `dsh run`。现有自定义一次性 profile 可继续通过 `--profile` 工作；常驻 profile 和配置 dump 保留既有的根命令语法。与之竞争的应用文件命令必须单独改名并 rebase，不得共享或重载 `run`。

 ## Verification
 
 TUI and Headless Loader coverage run the real app packages in source and built modes. PTY-driven subprocess coverage is reserved for the TUI lifecycle; other entry-point smokes use the one-shot pipe protocol. Headless proves its task/result and tool-call contracts. Generated graphs and repository searches reject stale package, command, leaf, SDK-interface, `createStdioChat`, and `StdioRuntime` references.
 
-The built `dsh` bin rejects a piped TUI launch before Loader boot and points at its one-shot `-p` mode; `apps/cli/tests/built-bin.e2e.ts` pins that path, while `cli-demo`'s built-bin suite runs text, JSON, and structurally parsed `stream-json` output under plain Node, persists fresh sessions, and rejects invalid arguments and missing config without contaminating stdout.

+# Agent Note: Remove the separate CLI demo

+Status: implemented

+
+## Problem
+
+After [`dsh run`](../feature/2026-08-08-dsh-run-headless-command.md) became the product one-shot command, `@deepseek-ai/dsh-cli-demo` remained a second application package for the same job. It carried another executable, argument grammar, app composition, cancellation lifecycle, text/JSON/stream-JSON output contract, built artifact, documentation surface, and test suite. The two front doors also assembled different trees, so a successful demo did not prove the shipped `headless` profile and users had to choose between overlapping commands.
+
+The replay suites still need canonical session events to pin assembled backend behavior. That testing need does not require a published command or compatibility contract.
+
+## Decision
+
+Delete `@deepseek-ai/dsh-cli-demo` completely: its package, bin, parser, app plugin, output formats, tests, workspace references, generated-catalog entries, and active documentation. No alias or compatibility package remains. The root `demo:headless` script is retained only as a direct alias of `dsh run`; the product command owns final-text stdout, the observation URL on stderr, persistence, exit status, and shutdown.
+
+`examples/headless-agent` becomes an explicit test composition. Its Loader configs mount `@deepseek-ai/dsh-agent-spine-demo`, one root agent, JSONL persistence, and checkpoint policy as separate rows instead of hiding them behind an app bundle. The support-tier `@deepseek-ai/dsh-loader-smoke` package owns the shared direct-agent turn helper; unexported example-local drivers select their Loader configuration and render canonical events as JSONL. They are launched only by tests, have no bin, and do not define a supported product output format.
+
+## Alternatives considered
+
+- **Keep `dsh-cli-demo` as an alias or wrapper around `dsh run`.** Rejected because a second bin and package would preserve two discoverable owners without adding capability.
+- **Move JSON and stream-JSON flags onto `dsh run`.** Rejected because no current product consumer requires them; adopting the old demo protocol would enlarge the canonical CLI contract solely to save test machinery.
+- **Delete the canonical-event snapshots with the package.** Rejected because they pin model-visible assembled behavior that final-text product acceptance cannot observe.
+- **Keep the app plugin but delete only its bin.** Rejected because the hidden composition would still duplicate the explicit headless profile and conceal which services the test leaf mounts.
+
+## Consequences
+
+This is intentionally breaking. `dsh-cli-demo`, its `--output-format` choices, and imports from `@deepseek-ai/dsh-cli-demo/src/cli.ts` no longer resolve. There is no public event-stream replacement in this change; callers use `dsh run` for one-shot execution and must choose an existing protocol surface when they need structured automation.
+
+The repository retains backend replay coverage through test-only infrastructure, while product smoke and built-bin acceptance exercise `dsh run`. A separate one-shot package may return only if it owns a genuinely independent, versioned protocol that cannot belong to the product launcher; a second spelling or output shim is not enough.
+
+## Verification
+
+Focused Loader smokes cover the explicit composition in source and plain-Node built modes, snapshot tests diff its canonical JSONL and persisted logs, product acceptance covers `dsh run`, and documentation plus generated graph/catalog gates reject live references to the removed package. The frozen Agent Note archive remains historical evidence and is not rewritten.

+# Agent Note: 移除独立的 CLI demo

+Status: implemented

+
+## 问题
+
+在 [`dsh run`](../feature/2026-08-08-dsh-run-headless-command.md) 成为产品的一次性命令后，`@deepseek-ai/dsh-cli-demo` 仍是承担同一工作的第二个应用包。它另行拥有一套可执行文件、参数语法、应用组装、取消生命周期、文本／JSON／stream-JSON 输出契约、构建产物、配套文档和测试套件。两个入口组装的树也不相同，因此 demo 成功不能证明已交付的 `headless` profile 可用，用户还必须在功能重叠的命令之间作出选择。
+
+回放套件仍需要规范会话事件来固定组装后的后端行为。这一测试需求不需要已发布命令或兼容性契约。
+
+## 决策
+
+彻底删除 `@deepseek-ai/dsh-cli-demo`：包括它的包、bin、解析器、应用插件、输出格式、测试、workspace 引用、生成目录条目和现行文档。不保留别名或兼容包。根目录的 `demo:headless` 脚本仅作为 `dsh run` 的直接别名保留；stdout 上的最终文本、stderr 上的观察 URL、持久化、退出状态和关闭行为均由产品命令负责。
+
+`examples/headless-agent` 成为显式测试组装。其 Loader 配置把 `@deepseek-ai/dsh-agent-spine-demo`、一个根 agent（智能体）、JSONL 持久化和检查点策略挂载为独立配置行，不再将其隐藏在应用组合包之后。支持层的 `@deepseek-ai/dsh-loader-smoke` 包负责共享的直接 agent 轮次 helper；未导出的示例本地 driver 选择各自的 Loader 配置，并将规范事件渲染为 JSONL。这些 driver 只由测试启动，不提供 bin，也不定义受支持的产品输出格式。
+
+## 考虑过的替代方案
+
+- **保留 `dsh-cli-demo` 作为 `dsh run` 的别名或包装层。** 不予采纳：第二个 bin 和包会让同一功能继续存在两个可发现的归属方，却没有增加任何能力。
+- **把 JSON 和 stream-JSON 标志移到 `dsh run`。** 不予采纳：当前没有产品消费方需要这些标志；沿用旧 demo 协议，只会为了保留测试机制而扩大规范 CLI（命令行界面）契约。
+- **随包一并删除规范事件快照。** 不予采纳：这些快照固定了模型可见的组装行为，而只检查最终文本的产品验收无法观察这些行为。
+- **保留应用插件，只删除它的 bin。** 不予采纳：隐藏的组装仍会重复显式的 headless profile，并掩盖测试叶节点挂载了哪些服务。
+
+## 后果
+
+这是有意为之的破坏性变更。`dsh-cli-demo`、它的 `--output-format` 选项以及对 `@deepseek-ai/dsh-cli-demo/src/cli.ts` 的导入都不再可解析。本变更不提供公开的事件流替代接口；调用方使用 `dsh run` 执行一次性任务，需要结构化自动化时则必须选择现有的协议接口。
+
+仓库通过仅供测试的基础设施保留后端回放覆盖，产品冒烟测试和 built-bin 验收则运行 `dsh run`。只有当独立的一次性包负责一套真正独立、带版本且不能归产品启动器所有的协议时，它才可以重新引入；第二种命令写法或输出 shim 并不足以构成理由。
+
+## 验证
+
+聚焦的 Loader 冒烟测试在源码模式和由普通 Node 启动的构建模式下覆盖显式组装，快照测试对比其规范 JSONL 和持久化日志，产品验收覆盖 `dsh run`，文档检查及生成图谱／目录门禁则拒绝对已移除包的活跃引用。冻结的 Agent Note 归档保留为历史证据，不会被重写。

 ## Plugin management
 
 `dsh plugin --profile <name> <args...>` initializes the profile when missing (shipped template, or `@deepseek-ai/dsh-base` alone for other names), then forwards `<args...>` to `pnpm` with the profile directory as working directory — `add`, `remove`, `why`, `update`, and every other pnpm verb work unchanged; pnpm must be on PATH. Relative path specs (`.`, `../plugin`, and their `file:`/`link:` forms) are anchored to the invoking directory first, so `add .` from a plugin checkout installs that checkout, not the profile. After every successful run, `dsh.profile.bundles` is reconciled against the installed state: each dependency resolving to a package whose manifest declares `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }` joins the layer stack (so an `update` that gains the declaration activates it), a bundle-less dependency stays plain with a one-time warning, and a removed dependency leaves the stack.

+`dsh run [--profile <name>] [--patch <path>...] <task...>` 会用空格拼接任务参数，拒绝缺失或空白任务，并让 `--profile` 默认为 `headless`。可重复使用的 `--patch` overlay 与 profile 启动的 overlay 位于同一层。所选的自定义 profile 必须挂载 `headless-runner`；否则启动器会在启动前失败，并在诊断中指明缺少该行。
+
+启动器把任务文本 patch 进运行器行，运行器再通过进程内 API 载体驱动一个全新的持久化会话，在 stdout 打印最终 assistant 文本，并在轮次完成时以 0 退出，否则以 1 退出。到达 idle 边界时，运行器会等到 mux 消费方观察到会话的最终事件序号，再生成输出与退出原因。会话的 Web 宿主运行在 OS 分配的端口上并公布到 stderr，因此该次运行可在浏览器中观察。
+
 ## 插件管理
 
 `dsh plugin --profile <name> <args...>` 在 profile 缺失时先初始化它（有随附模板的用模板，其他名称只装 `@deepseek-ai/dsh-base`），然后以 profile 目录为工作目录，把 `<args...>` 转发给 `pnpm`：`add`、`remove`、`why`、`update` 及其他所有 pnpm 子命令都照常可用；pnpm 必须在 PATH 上。相对路径 spec（`.`、`../plugin` 及其 `file:`/`link:` 形式）会先锚定到调用目录，因此在插件 checkout 中执行 `add .` 安装的是该 checkout，而不是 profile。每次成功运行后，`dsh.profile.bundles` 都会与已安装状态对齐：每个解析到 manifest 中声明了 `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }` 的包的依赖加入层栈（因此让包获得该声明的 `update` 会将其激活），没有组合包声明的依赖保持为普通依赖并给出一次性警告，已移除的依赖则退出层栈。

@@ -9,7 +9,7 @@ How this repo tests, tier by tier, and the rules that keep a green suite meaning
 - **Unit** (`pnpm run test`): vitest over package and example specs under their `tests/**` directories plus repository script specs under `scripts/**/*.spec.ts`; tests stay with the code area they exercise. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped. Per-file 100% on `packages/bash/pwsh-local/src` needs a real `pwsh`: without one its executor suites self-skip and `vitest.config.ts` exempts the file so pwsh-less hosts stay green, while CI runners ship pwsh and enforce the full bar.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
-- **Snapshot** (`pnpm run test:snapshot`): keyless expected outputs cover external behavior — transport contracts and presentation, while persisted logs pin assembled backend behavior. ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless pins `stream-json` through its real one-shot process. Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).

ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless backend scenarios boot their explicit example composition through an unexported JSONL test driver, while `apps/cli` separately owns product `dsh run` acceptance. Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares replayed browser output with `apps/web/tests/snapshots/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.
 
 Committed session-format JSONL uses the canonical packed-row layout, and the keyless snapshot gate discovers every such fixture by its `session` header. In-flight branches carrying older fixture edits merge current `master` and run the [temporary migrator](../scripts/migrate-packed-session-fixtures.ts) through `pnpm run migrate:packed-session-fixtures`; the [removal proposal](../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) retires that command and these links after all affected branches converge.

+The product command is [`dsh run`](../../apps/cli/README.md): it accepts one nonblank task, creates and persists a fresh session, prints the final assistant text, and exits. The root `demo:headless` script is only an alias of that command.
 
-Each invocation creates and persists a fresh session, runs all model and tool steps in one turn, flushes, disposes, and exits.
