## Decision
The `dsh` TUI, Web, and headless source launches run `node --import tsx/esm`: tsx's ESM-only hook owns both TypeScript transformation and tsconfig `paths` projection. `bin/dsh`, the root `dsh`/`demo:tui`/`demo:web` scripts, and the Code Mode TUI overlay use the same vector; `bin/dsh` references the hook and tsconfig by absolute checkout paths (bare `tsx/esm` does not resolve from an arbitrary cwd) and pins `TSX_TSCONFIG_PATH` to the root tsconfig. The CJS hook stays off because the CLI source graph is ESM-only; measured TUI time-to-banner is ~0.7s versus ~1.1s under the full tsx default and ~0.75s under the removed native chain.
The `dsh` TUI, Web, and headless source launches run `node --import tsx/esm`: tsx's ESM-only hook owns both TypeScript transformation and tsconfig `paths` projection.

The CJS hook stays off because the CLI source graph is ESM-only; measured runtime launch to the TUI banner is ~0.7s versus ~1.1s under the full tsx default and ~0.75s under the removed native chain.
`scripts/tspath-loader.ts` and `apps/cli/src/tsconfig-paths-loader.ts` are deleted. With them went the loader's runtime rule of mapping a workspace import only for declared runtime dependencies — tsx applies the `paths` map unconditionally. Declaration completeness now rests on the static gates alone: `verify-cordis-config` for configured bare plugins, and workspace constraints for manifests. (That runtime rule found real bugs: `dsh-plan-mode` and `dsh-tool-tasks` imported `@deepseek-ai/dsh-llm` while declaring it only in devDependencies; since fixed.)

# Agent Note: A minimal read_image tool over existing seams
Status: implemented
English | [中文](2026-08-10-minimal-read-image-tool.zh.md)
## Problem
The multimodal attachment work gave user uploads a complete durable path — bytes committed to the content-addressed attachment store before the owning `user/message`, an `ImageBlock` carrying only the `sha256:` reference, and the pi-ai route re-reading verified bytes per request — but the model itself had no way to look at an image on disk. `read` rejects binary content by contract, so an agent asked about a screenshot or a rendered chart either failed or shelled out to lossy workarounds. A first standalone attempt (PR #598) solved this together with loop-level route scoping: an `agent/request-ready` extension point publishing exact-model modalities before assembly, per-route schema/guidance visibility, and a reversible `image-placeholder-v1` history projection so text routes could continue over placeholder text. That design worked but coupled a tool to new agent-loop machinery, three new session-log concepts, and per-step registration churn — far more surface than the capability needs.
## Decision
Ship the smallest tool that loads an image into the next request's context, entirely over existing seams; the withdrawn PR #598 design is the explicit counter-example this note records.
- **`read_image` lives in `dsh-tool-fs`** beside `read`/`write`/`edit`. Extension selects the declared PNG/JPEG/WebP/GIF media type; the attachment store's magic-byte and pixel validation stays authoritative. Bytes travel `ctx.fs.stat` → bounded `ctx.fs.readBytes` → `ctx.attachments.saveImage` → `fs/observed`, and the tool result is the metadata envelope plus a real `ImageBlock` — `ToolResultBlock.content` already admits image blocks, the pi-ai adapter already renders them, and the Web host's model-switch guard already scans tool results, so nothing downstream changes.
- **`FileSystem.readBytes(target, signal, maxBytes)`** is a new required provider primitive: the byte bound lives at the seam so no backend can buffer an unbounded file, with the stat-size short-circuit and a one-byte-past-cap stream guard against post-stat growth (`FS_TOO_LARGE`).
- **Registration is composition-conditional, execution is route-gated.** The tool registers only under `ctx.inject(['attachments'], …)` — no store, no tool. At execution, before any I/O, the strict gate resolves the calling route (latest `request/header` config, falling back to agent options) through `ctx.llm.resolveModelInfo` and requires `image` in `inputModalities`; unknown capability refuses. A refusal is a plain `isError` result, so a text route's durable history never acquires an image block and the session cannot brick its own route.
- **Code Mode forwards the image out-of-band**: a nested dispatch returns the canonical value (execution-local, no image block) and defers a `user`-role context message carrying the envelope and image, so the picture still reaches the next request.
- **llm-replay models may declare `inputModalities`**, which is what lets the two keyless ACP snapshots pin both sides of the gate — the sha256-referenced success on an image-capable replay route and the verbatim refusal on a text-only one.
## Alternatives considered
- **PR #598's route-scoped design** (request-ready seam, per-route schema/guidance visibility, reversible history projection) — withdrawn in favor of this note's shape. What it bought: text routes could keep running after images entered history, and the tool disappeared from prompts where it cannot succeed. What it cost: agent-loop changes, three new durable concepts (`agent/request-ready`, `messageProjection`, availability notices), and registration that churned per step. The capability itself — see an image on the next request — never needed any of it. If per-route projection becomes a real requirement, that PR's history is the reference implementation.
- **`agent.inject()` instead of the image-bearing tool result** — routes the image around the tool result as a separate injected user message. Rejected: the image *is* the tool's result; splitting them adds a second logged message with no gain, and the tool-result path already works end to end.
- **Magic-byte sniffing instead of extension declaration** — sniffing duplicates detection the attachment store already owns (sharp-backed, authoritative). The extension is only a *declaration*; a mismatch fails closed with a rename remedy rather than being silently accepted, which also keeps the model's mental map (file name ↔ content) honest.
- **Registering unconditionally and failing on a missing store** — rejected; a deployment without an attachment store cannot ever satisfy the tool, so its schema would be a standing lie. The route gate, by contrast, is per-call state and correctly lives at the execution boundary.
## Consequences
- A text-only route refuses instead of degrading: no placeholder projection means no delegated-viewing story here — that is deliberately the next PR (subagent image readback rebuilt on the current subagent seams).
- The route gate races a concurrent model switch; the Web host's image-aware switch guard covers its surface, and other front doors own their equivalent. Recorded as a tool-fs Known Limitation.
- Repeated image results accumulate request-token cost until compaction; content addressing deduplicates bytes only.
- The tool-result card renders the durable reference, not pixels; inline preview is deferred to the UI packages.

# Agent Note: 基于既有 seam 的最小 read_image 工具
Status: implemented
[English](2026-08-10-minimal-read-image-tool.md) | 中文
## 问题
多模态附件工作为用户上传建立了完整的持久路径:字节在所属 `user/message` 之前提交到内容寻址的附件存储,`ImageBlock` 只携带 `sha256:` 引用,pi-ai 路由在每次请求时重新读取并校验字节。但模型自己没有查看磁盘图像的手段。`read` 按约定拒绝二进制内容,因此被问到截图或渲染图表的 agent 要么失败,要么退到有损的变通做法。第一次独立尝试(PR #598)把这个问题与循环级路由作用域一起解决:新增在组装前发布确切模型模态的 `agent/request-ready` 扩展点、按路由控制 schema/指导可见性,以及可逆的 `image-placeholder-v1` 历史投影让文本路由能在占位符上继续。该设计可行,但让一个工具耦合了新的 agent-loop 机制、三个新的会话日志概念和每步的注册变动,远超这项能力本身的需要。
## 决定
只交付能把图像载入下一次请求上下文的最小工具,完全建立在既有 seam 之上;撤回的 PR #598 设计是本记录明确保留的反例。
- **`read_image` 放在 `dsh-tool-fs`**,与 `read`/`write`/`edit` 并列。扩展名选择声明的 PNG/JPEG/WebP/GIF 媒体类型;附件存储的魔数与像素校验保持权威。字节沿 `ctx.fs.stat` → 有界 `ctx.fs.readBytes` → `ctx.attachments.saveImage` → `fs/observed` 流动,工具结果是元数据信封加真正的 `ImageBlock`——`ToolResultBlock.content` 本就允许图像块,pi-ai 适配器本就会渲染它们,Web 宿主的模型切换防护本就会扫描工具结果,下游无需任何改动。
- **`FileSystem.readBytes(target, signal, maxBytes)`** 是新的必备提供方原语:字节上限放在 seam 上,任何后端都无法无界缓冲文件;stat 大小先短路,随后的流最多多读一个字节以防 stat 之后的增长(`FS_TOO_LARGE`)。
- **注册随组合条件挂载,执行按路由门禁。** 工具只在 `ctx.inject(['attachments'], …)` 作用域内注册——没有存储就没有工具。执行时在任何 I/O 之前,严格门禁通过 `ctx.llm.resolveModelInfo` 解析调用路由(最新 `request/header` 配置,缺失时回退到 agent 选项),要求 `inputModalities` 包含 `image`;能力未知即拒绝。拒绝是普通的 `isError` 结果,因此文本路由的持久历史绝不会出现图像块,会话不会毁掉自己的路由。
- **Code Mode 以带外方式转发图像**:嵌套分派返回规范值(仅限本次执行,不含图像块),并延迟提交一条携带信封和图像的 `user` 角色上下文消息,图片仍会到达下一次请求。
- **llm-replay 模型可以声明 `inputModalities`**,这正是两个 keyless ACP 快照能钉住门禁两侧的原因:图像路由上以 sha256 引用的成功结果,和纯文本路由上逐字的拒绝。
## 考虑过的替代方案
- **PR #598 的路由作用域设计**(request-ready 扩展点、按路由的 schema/指导可见性、可逆历史投影)——被本记录的形态取代后撤回。它换来的是:图像进入历史后文本路由仍能运行,工具在注定失败的提示词里消失。它付出的是:改动 agent-loop、三个新的持久概念(`agent/request-ready`、`messageProjection`、可用性通知)和每步变动的注册。而这项能力本身——下一次请求看到图像——从不需要这些。如果按路由投影将来成为真实需求,该 PR 的历史就是参考实现。
- **用 `agent.inject()` 代替带图像的工具结果**——把图像绕过工具结果,作为单独注入的用户消息。拒绝:图像就是工具的结果;拆开只会多一条无收益的日志消息,而工具结果路径本就端到端可用。
- **用魔数嗅探代替扩展名声明**——嗅探重复了附件存储已拥有的检测(基于 sharp,权威)。扩展名只是声明;不匹配时按改名修复提示失败关闭,而不是被静默接受,这也让模型对文件名与内容的对应保持诚实。
- **无条件注册、缺存储时执行报错**——拒绝;没有附件存储的部署永远无法满足该工具,其 schema 会是常态谎言。相反,路由门禁是逐调用状态,正确的位置就是执行边界。
## 后果
- 纯文本路由得到拒绝而不是降级:没有占位符投影意味着这里没有委托查看的方案——那有意留给下一个 PR(基于当前 subagent seam 重建的 subagent image readback)。
- 路由门禁与并发模型切换存在竞态;Web 宿主的图像感知切换防护覆盖其表面,其他前端拥有各自的等价防护。已记入 tool-fs 的已知限制。
- 重复的图像结果在压缩之前持续累积请求 token 成本;内容寻址只去重字节。
- 工具结果卡片渲染持久引用而非像素;内嵌预览延后到 UI 包处理。

# Agent Note: Personal staging maintenance skills
Status: implemented
English | [中文](2026-07-23-personal-staging-maintenance-skills.zh.md)
## Problem
Personal dsh customizations need a repeatable way to locate the installed source, isolate task work, serialize integration, and incorporate upstream changes without rewriting the checkout used by running sessions. User-local instructions solve this for one installation but cannot guide other users or remain synchronized with repository installer behavior.
## Decision
The repository distributes [`dsh-customize`](../../../../skills/dsh-customize/SKILL.md), [`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md), and [`dsh-upstream-customization`](../../../../skills/dsh-upstream-customization/SKILL.md) from its root `skills/` directory. Their descriptions name both the operation and user requests that select it. The shipped TUI supplies that directory to the local skill provider at startup, below project and user roots in discovery priority. The workflows derive the active checkout and staging branch from the installed launcher rather than a user-specific path or branch name, defer to repository-local instructions, require task worktrees, and serialize staging mutations with the staging worktree's established `.agents/merge.lock`.
Before rebasing, an upgrade inspects the Git log and commit ranges to identify incoming upstream changes, personal commits, duplicates, and likely conflicts. It drops customizations already supplied upstream; when only a documentary local diff remains for such a customization, it also drops that account unless it adds an independently useful current contract absent upstream. Each attempt uses one UTC basic timestamp for its independent `dsh-staging-<timestamp>` sibling clone, local `dsh-upgrade/prepare-<timestamp>` branch, new `dsh-staging/<timestamp>` branch, private upstream and recovery refs, and launcher backup. The sibling name does not derive from the current directory name, and collisions fail rather than acquiring ad hoc suffixes. The workflow derives the current DSH process source from the process command and runtime environment rather than the shell working directory, then treats the repository and checkout behind the installed launcher as immutable except for holding its existing merge lock.
After validation in the independent clone, the workflow creates and verifies the timestamped staging branch, then atomically moves the launcher once from the unchanged old staging checkout to the new staging checkout. The launcher never targets a preparation, feature, review, publication, or detached checkout. Failure before cutover leaves the installed checkout and launcher unchanged; failure after cutover restores and verifies the launcher backup. The old staging checkout, its branch, the recovery ref, and the launcher backup remain available until a restarted process proves that DSH runs from the new staging branch and the user explicitly approves rollback cleanup.
`dsh-upstream-customization` owns upstream publication independently from local maintenance and upgrades. It recommends bug fixes, additive non-conflicting plugin features, and visual improvements; intrusive changes require maintainer approval first. At the end of an upgrade, the agent classifies remaining customizations, explains their upstream value, recommends whether to propose each one, and asks which named candidate the user wants to upstream. Only that selection loads the publication workflow; each feature still requires explicit approval before a push or draft PR. Approved changes start from current upstream `master` without unrelated personal commits. Draft PRs for TUI features preferably include a screenshot from the assembled application after credentials and personal data are removed. `dsh-customize` requires interactive TUI behavior to be exercised in a dedicated tmux session before integration.
## Alternatives considered
**Keep the workflows user-scoped.** This preserves personal flexibility but prevents other users from discovering the same safety rules and lets the workflow drift from the installer shipped by the repository.
**Rebase the active staging checkout in place.** This is simpler but changes many files during preparation, can disrupt new dsh launches, and cannot provide atomic publication or an unchanged rollback checkout.
**Update the existing staging checkout after moving the launcher elsewhere.** This retains one staging path but requires a mid-upgrade launcher target that is not a staging branch and still rewrites a checkout that may host a running process.
**Lock only the final branch switch.** This shortens lock duration but permits a customization merge against the old base while the rebase is being prepared, invalidating the prepared history.
**Open one upstream PR for all personal changes.** This reduces branch management but publishes unrelated customizations and removes the user's per-feature approval boundary.
## Consequences
Upgrade preparation holds the installed staging merge lock while dependencies and checks run, so local customization integration waits for a consistent result. One upgrade creates an independent timestamped clone and staging branch, performs one atomic launcher cutover, and requires one restart afterward; it never writes into the repository or checkout behind the launcher except to hold its existing lock. Each workflow records preconditions, repeats them before mutation, inspects state after interrupted mutations, restores the launcher backup on cutover failure, reruns failed checks after correction, and reports final state. The old staging checkout remains rollback storage until explicit user-approved cleanup. Checked-in evaluations cover selection, process-source protection, unsafe repository states, rollback, and publication authorization; repository documentation checks validate skill links and formatting, while technical review remains responsible for Git and filesystem correctness.

# Agent Note: 个人集成分支维护 skill
Status: implemented
[English](2026-07-23-personal-staging-maintenance-skills.md) | 中文
## 问题
个人 dsh 定制需要一套可重复执行的方法,用于定位已安装的源码、隔离各项任务的修改、串行集成变更,并在不改写运行中会话所用检出的前提下合入上游变更。用户本地指令能解决某一套安装中的问题,却无法指导其他用户,也无法持续与仓库安装脚本的行为保持同步。
## 决策
仓库从其根 `skills/` 目录分发 [`dsh-customize`](../../../../skills/dsh-customize/SKILL.md)、[`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md) 和 [`dsh-upstream-customization`](../../../../skills/dsh-upstream-customization/SKILL.md)。它们的描述同时说明操作内容和选择该 skill(技能)的用户请求。分发的 TUI 在启动时将该目录提供给本地 skill 提供方,在发现优先级上位于项目根目录和用户根目录之后。这些 skill 根据已安装的启动器而非个人路径或分支名称定位当前生效的检出和集成分支,遵从仓库内指令,要求使用任务 worktree,并利用集成分支所在 worktree 的既有 `.agents/merge.lock`,串行执行每一次个人集成分支修改。
升级流程在变基前检查 Git 日志和提交范围,以识别将进入升级的上游变更、个人提交、重复内容和可能发生冲突的区域。它会丢弃上游已经提供的定制;如果这类定制在本地只剩文档差异,也会一并丢弃,除非该说明包含上游缺失且可独立使用的当前约定。每次升级尝试使用同一个 UTC 基本格式时间戳,用于其独立的 `dsh-staging-<timestamp>` 同级克隆、本地 `dsh-upgrade/prepare-<timestamp>` 分支、新的 `dsh-staging/<timestamp>` 分支、私有的上游引用与恢复引用,以及启动器备份。同级克隆的名称不派生自当前目录名,名称冲突会直接失败,而不是追加临时后缀。流程根据进程命令和运行时环境而非 shell 工作目录推导当前 DSH 进程的源码位置,随后将已安装启动器所指向的仓库和检出视为不可变,唯一例外是持有其既有合并锁。
在独立克隆中验证通过后,工作流会创建并验证带时间戳的集成分支,然后以原子方式将启动器从保持不变的旧集成分支检出一次性切换到新集成分支检出。启动器绝不会指向准备、功能、评审、发布或处于分离状态的检出。切换前的失败会让已安装的检出和启动器保持不变;切换后的失败则恢复并验证启动器备份。旧的集成分支检出、其分支、恢复引用和启动器备份会一直保留,直到重启后的进程证明 DSH 运行于新的集成分支,且用户明确批准回滚清理为止。
`dsh-upstream-customization` 独立于本地维护和升级,负责向上游发布。它推荐 bug 修复、附加式且不冲突的插件功能,以及视觉改进;侵入式变更需先取得维护者批准。在升级结束时,agent 会对剩余定制进行分类、说明其上游价值、建议是否提交,并询问用户希望向上游贡献哪个具名候选项。只有用户做出选择后才会加载发布工作流;每项功能在推送或创建草稿 PR(Pull Request)前仍必须得到明确批准。获批的变更均以当前上游 `master` 为起点,不带入无关的个人提交。TUI 功能的草稿 PR 建议在移除凭证与个人数据后,附上组装后应用的截图。`dsh-customize` 要求在集成前于专用 tmux 会话中检验交互式 TUI 行为。
## 备选方案
**将这些工作流限定在用户本地。** 这样可以保留个人使用的灵活性,但其他用户无法发现同一套安全规则,工作流也可能逐渐偏离仓库分发的安装脚本行为。
**在当前集成分支检出中原地变基。** 此方案更简单,但准备期间会修改大量文件,可能干扰新的 dsh 启动,也无法实现原子发布或提供一份保持不变的回滚检出。
**在将启动器迁往别处后更新现有的集成分支检出。** 此方案可以保留单一的集成分支路径,却要求在升级中途让启动器指向一个并非集成分支的目标,且仍会改写可能承载运行中进程的检出。
**只在最终切换分支时加锁。** 这样可以缩短持锁时间,却允许写入方在变基准备期间继续基于旧基线合并定制变更,导致准备好的历史失效。
**用一个上游 PR 发布所有个人变更。** 这会减少分支管理工作,却会发布无关的定制,并取消用户按功能逐项批准的边界。
## 影响
升级准备流程在安装依赖和运行检查期间持有已安装集成分支的合并锁,因此本地定制的集成必须等待一致的结果。一次升级会创建独立的带时间戳的克隆和集成分支,执行一次原子的启动器切换,并在切换后要求重启一次;除持有其既有锁之外,升级绝不会写入启动器所指向的仓库或检出。各工作流会记录前置条件、在修改前重复检查、在修改被中断后检查状态、在切换失败时恢复启动器备份、修复后重新运行失败的检查,并报告最终状态。旧的集成分支检出会作为回滚存储一直保留,直到用户明确批准清理为止。仓库内评估覆盖 skill 选择、进程源码保护、不安全的仓库状态、回滚和发布授权;仓库文档检查会验证 skill 的链接和格式,Git 与文件系统操作的正确性仍由技术评审负责。

# Agent Note: the installer adopts an existing checkout into the managed layout
Status: implemented
English | [中文](2026-07-31-installer-adopts-existing-checkout.zh.md)
## Problem
`scripts/install.sh` produced two incompatible installation layouts. A `curl … | sh` install built the managed layout — a master clone at `~/.dsh/source/master`, a staging worktree on `dsh-staging/<timestamp>`, and the stable `current` symlink the PATH launcher resolves through. Running the same script from a checkout instead linked `dsh` straight at that checkout's `bin/dsh`, per the earlier [in-repo skip-clone decision](../../archived/process/2026-07-22-installer-in-repo-skip-clone.md).
The direct link cannot be upgraded. `current` is what an upgrade repoints, so an install without it is not upgradable by [`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md); the PATH symlink dangles if the checkout moves; and the launcher resolves to whatever branch the contributor happened to have checked out, which the upgrade contract forbids as a launcher target. The upgrade skill already described this layout as a legacy install needing a one-time migration, so the layouts diverged at install time and were reconciled only later, if ever.
## Decision
In-repo mode still never clones and never modifies the working tree, but it now **adopts** the checkout into the managed layout unconditionally. There is no opt-out: one layout serves every install.
The container owns staging worktrees and `current`; the repository is *discovered*, not owned. `git rev-parse --git-common-dir` resolves the shared git directory behind the checkout — for a linked worktree that is the real clone rather than the worktree itself — and its parent is the repository that serves as the upgrade base. A staging worktree branched from the checkout's `HEAD` is then created under `$DSH_SOURCE`, and `current` points at it. A clone anywhere on disk therefore converges on the same layout as a `curl` install, and the two paths share one worktree/exclude/lock/link sequence: they differ only in whether the repository was discovered by `git clone` or by `git rev-parse`.
The installer records nothing about where that repository lives. A container whose repository sits outside it is not self-contained — each staging worktree holds an absolute gitdir pointer into that clone, so deleting the clone breaks them — but git already owns that fact: the worktree's `.git` file names the path, and `git worktree list` in the clone enumerates every worktree depending on it.
Adoption branches from `HEAD`, so committed work is what runs and uncommitted changes stay in the checkout. This is not prompted or warned about: the installer builds the layout and gets out of the way. Setting `DSH_SOURCE` to a different directory remains the one documented way to opt back into cloning a separate tree.
Every path comparison runs on physical paths through a `resolve_dir` helper, and every compared value is resolved at assignment rather than at the comparison. Git always reports resolved paths, so comparing one against an unresolved path disagrees whenever a symlink sits anywhere above the checkout — a symlinked home directory is enough, and macOS reaches every `mktemp` path that way through `/var` -> `private/var`. The mismatch misclassified an existing managed install as a foreign clone and would have built a second container beside the real one. The same defect class recurs whenever one side of a comparison is left unresolved — as it did with a curl install's `REPO_ROOT` and with the container path it was compared against. `resolve_dir` therefore echoes a missing path back rather than failing, so a not-yet-created container needs no per-call fallback and no site can compare against an empty path by forgetting one; callers that need "does not exist" test the directory explicitly. `git rev-parse --path-format=absolute` would do the same job but requires git 2.31+.
Before `current` is repointed, the installer rejects a staging path that resolves to the repository itself, enforcing the upgrade contract that the launcher never resolves to the master clone.
## Alternatives considered
**Make `~/.dsh/source/master` a symlink to the arbitrary clone.** Rejected. Git resolves the symlink and records the *real* path: a worktree created through it stores `gitdir: …/<clone>/.git/worktrees/<name>`, and `git worktree list` reports the clone. The symlink is therefore decorative — nothing reads it — while implying the container owns the repository. It also fails silently: moving the clone leaves `master` present but dangling and every staging worktree dead with `fatal: not a git repository`. Worst, it aliases two names onto one tree, so the "current must never be the master clone" check passes by string comparison while being false. `~/.dsh/source/master` is a location, not a name, and only the location is authoritative.
**Promote the checkout itself to the `current` target.** Rejected: the upgrade contract requires `current` to point to a clean staging worktree on a staging branch, never a feature, review, or detached checkout. It would also make every upgrade rewrite the tree the contributor is editing.
**Keep link-in-place behind a prompt or a `DSH_ADOPT` flag.** Rejected, and an earlier revision of this change shipped exactly that before it was removed. The second layout was the defect itself, so retaining it as an option preserves the problem and doubles the states every later change must handle — the prompt, the flag, the dirty-tree warning, and a second linking path all existed only to keep a layout nothing should produce. The original motivation for link-in-place, keeping the script testable against local source, survives adoption: a staging worktree branched from the checkout's `HEAD` runs the same code. `DSH_SOURCE` remains available for installing a separate tree.
**Warn or prompt when the tree is dirty.** Rejected: `worktree add` from `HEAD` cannot carry uncommitted work, so the behavior is determined and a prompt only adds a decision the user cannot act on differently. The contract is documented instead.
**Put an adopted clone's staging worktrees beside the clone** (`~/src/staging-*`) rather than in `~/.dsh/source`. Rejected: `current` and the PATH launcher are per-user singletons, so scattering worktrees across clone parents reintroduces the sibling-clone sprawl the source container exists to prevent.
## Consequences
One layout now serves every install, so an adopted clone is upgradable by `dsh-upgrade` without the one-time migration that skill described, and the installer has no branch that produces an unupgradable layout. In-repo runs still never mutate the working tree.
The cost is that a contributor can no longer point PATH at a checkout and have `dsh` follow that working tree as they switch branches: the launcher now resolves to a staging worktree pinned to the `HEAD` adopted at install time. Re-running the installer adopts the current `HEAD` again.
A container adopting an outside clone is also no longer self-contained: deleting that clone breaks its staging worktrees. This is inherent to reusing an existing clone rather than a property of this design — the rejected symlink hides it rather than fixing it — and git's own worktree records are what diagnose it.
## Testing
`scripts/install.sh` now has a real-shell PTY regression suite in `apps/cli/tests/install-script.spec.ts`, covering adoption and curl-style paths with stubbed dependencies. Curl-style installs default to the public `deepseek-ai/deepseek-harness-sdk` source, while replacing the installer with pnpm/npx remains separate work.
Verification was manual, through a throwaway harness driving the real script with a stubbed `pnpm`: adopting a standalone clone; adopting from a linked worktree into its existing container; an explicit `DSH_SOURCE` still opting back into cloning; a dirty tree adopting silently with no prompt or warning while its uncommitted file stays behind; a non-git checkout failing with guidance; and a `curl`-style clone install asserting the built layout, the check that catches an unresolved `REPO_ROOT`. The interactive path was exercised under tmux from a dirty checkout, confirming the run reaches the launcher with no adoption prompt and ends with `dsh` running from the new staging worktree while the original checkout keeps its branch and its uncommitted file.

# Agent Note: 安装器把已有检出接管进受管布局
Status: implemented
[English](2026-07-31-installer-adopts-existing-checkout.md) | 中文
## Problem
`scripts/install.sh`会产生两种互不兼容的安装布局。`curl … | sh`安装会构建受管布局——`~/.dsh/source/master`处的 master 克隆、位于`dsh-staging/<时间戳>`分支上的 staging worktree,以及 PATH 启动器据以解析的稳定`current`符号链接。而从检出中运行同一脚本时,则依据此前的[检出内跳过克隆决策](../../archived/process/2026-07-22-installer-in-repo-skip-clone.md),把`dsh`直接链接到该检出的`bin/dsh`。
这种直接链接无法升级。升级重指的正是`current`,因此缺少它的安装无法通过[`dsh-upgrade`](../../../../skills/dsh-upgrade/SKILL.md)升级;检出一旦移动,PATH 符号链接就会失效;而且启动器会解析到贡献者恰好检出的任意分支,这正是升级约定禁止作为启动器目标的情形。升级技能早已把这种布局描述为需要一次性迁移的旧式安装,因此两种布局从安装时起便不相同,只有以后执行迁移才会一致,而迁移也可能永远不执行。
## Decision
检出内模式仍然绝不克隆、绝不修改工作树,但现在它会无条件地把该检出**接管**进受管布局。不存在退出选项:一套布局服务于所有安装。
容器拥有 staging worktree 和`current`;仓库是被*发现*的,而非被拥有的。`git rev-parse --git-common-dir`会解析出该检出背后的共享 git 目录——对于 linked worktree,那是真正的克隆而非 worktree 自身——其父目录即是充当升级基础的仓库。随后以该检出的`HEAD`为起点,在`$DSH_SOURCE`下创建 staging worktree,并让`current`指向它。因此,磁盘上任意位置的克隆都会收敛到与`curl`安装相同的布局,且两条路径共用同一套 worktree/exclude/lock/link 流程:二者的唯一差别,只在于仓库是由`git clone`发现的,还是由`git rev-parse`发现的。
安装器不会记录该仓库位于何处。仓库位于容器之外时,容器就不是自包含的——每个 staging worktree 都持有指向该克隆的绝对 gitdir 指针,删除该克隆就会破坏它们——但这一事实本就由 git 自己掌握:worktree 的`.git`文件写明了该路径,而在该克隆中执行`git worktree list`会列出依赖于它的每一个 worktree。
接管以`HEAD`为分支起点,因此运行的是已提交的内容,未提交的更改仍留在检出中。这一点既不提示也不警告:安装器构建好布局后便不再打扰。把`DSH_SOURCE`设为其他目录,仍是唯一有文档记载的、回到克隆另一棵树的方式。
所有路径比较都通过`resolve_dir`辅助函数在物理路径上进行,且每个参与比较的值都在赋值时解析,而非在比较时解析。git 报告的始终是已解析的路径,因此只要检出之上任意一层存在符号链接,拿它与未解析的路径相比较就会不相等——家目录本身是符号链接即已足够,而 macOS 通过`/var` -> `private/var`使每个`mktemp`路径都如此。这种不匹配会把已有的受管安装误判为外来克隆,并在真正的容器旁再建一个容器。只要比较的一侧未经解析,同类缺陷就会重现——curl 安装的`REPO_ROOT`以及与之比较的容器路径都曾如此。因此`resolve_dir`在路径不存在时原样回显该路径而非失败,这样尚未创建的容器无需在每个调用点单独兜底,也就没有调用点会因遗漏兜底而与空路径比较;需要判断"不存在"的调用方则显式检测该目录。`git rev-parse --path-format=absolute`能完成同样的工作,但要求 git 2.31 及以上版本。
在重指`current`之前,安装器会拒绝解析结果等于仓库自身的 staging 路径,以此落实"启动器绝不解析到 master 克隆"这一升级约定。
## Alternatives considered
**把`~/.dsh/source/master`做成指向该任意克隆的符号链接。** 已否决。Git 会解析该符号链接并记录*真实*路径:经由它创建的 worktree 会存储`gitdir: …/<克隆>/.git/worktrees/<名称>`,而`git worktree list`报告的是该克隆。因此这个符号链接纯属装饰——没有任何代码读取它——却又暗示容器拥有该仓库。它还会静默失效:移动克隆后,`master`看似仍在却已悬空,而每个 staging worktree 都会以`fatal: not a git repository`失败。最糟的是,它把两个名称别名到同一棵树上,于是"current 绝不能是 master 克隆"这项检查会在字符串比较下通过,实则为假。`~/.dsh/source/master`是位置而非名称,且只有位置具有权威性。
**把检出自身提升为`current`的目标。** 已否决:升级约定要求`current`指向 staging 分支上的干净 staging worktree,绝不能指向 feature、review 或 detached 检出。这还会使每次升级都改写贡献者正在编辑的那棵树。
**把就地链接保留在提示或`DSH_ADOPT`开关之后。** 已否决;本次变更的早期修订版本正是如此实现,之后被移除。第二种布局本身就是缺陷,因此把它保留为一个选项等于保留了问题,并使此后每次改动必须处理的状态翻倍——提示、开关、工作树不干净的警告,以及第二条链接路径,全都只为维持一种本不该产生的布局而存在。就地链接最初的动机——让脚本能针对本地源码进行测试——在接管方案下依然成立:以检出的`HEAD`为起点创建的 staging worktree 运行的是同一份代码。`DSH_SOURCE`仍可用于安装另一棵树。
**在工作树不干净时发出警告或提示。** 已否决:以`HEAD`为起点的`worktree add`本就无法带上未提交的内容,因此该行为是确定的,提示只会增加一个用户无法做出不同选择的决策点。改为在文档中说明该约定。
**把被接管克隆的 staging worktree 放在该克隆旁边**(`~/src/staging-*`),而非放进`~/.dsh/source`。已否决:`current`和 PATH 启动器都是每用户唯一的,因此把 worktree 散落到各个克隆的父目录中,会重新引入 source 容器本就为之而设、意在杜绝的同级克隆蔓延问题。
## Consequences
现在一套布局服务于所有安装,因此被接管的克隆无需该技能所述的一次性迁移,即可由`dsh-upgrade`升级,而且安装器不再有任何一条分支会产生无法升级的布局。检出内运行仍然绝不改动工作树。
代价是:贡献者不能再把 PATH 指向某个检出、并让`dsh`随其切换分支而跟随该工作树;启动器现在解析到的是一个固定在安装时所接管`HEAD`上的 staging worktree。重新运行安装器会再次接管当前的`HEAD`。
此外,接管外部克隆的容器不再自包含:删除该克隆会破坏其 staging worktree。这是复用已有克隆的固有属性,而非本设计带来的性质——被否决的符号链接方案只是掩盖它,而非修复它——诊断依据则是 git 自身的 worktree 记录。
## Testing
`scripts/install.sh` 现有一套位于 `apps/cli/tests/install-script.spec.ts` 的真实 shell PTY 回归测试,使用 stub 依赖覆盖接管路径和 curl 风格路径。curl 风格安装默认使用公开的 `deepseek-ai/deepseek-harness-sdk` 源,而以 pnpm/npx 替换安装器仍是另一项工作。
验证是手工完成的,通过一个一次性测试装置以打桩的`pnpm`驱动真实脚本:接管独立克隆;从 linked worktree 接管进其已有容器;显式`DSH_SOURCE`仍回到克隆路径;工作树不干净时静默接管、既不提示也不警告,且其未提交文件留在原处;非 git 检出失败并给出指引;以及`curl`式克隆安装断言所构建的布局——该检查能捕获未解析的`REPO_ROOT`。交互路径在 tmux 下从一个不干净的检出走通,确认整个过程不出现接管提示即可到达启动器,最终`dsh`从新的 staging worktree 运行,而原检出保持其分支不变、未提交文件仍在。

`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.

# Agent Note: Source run without a managed installer
Status: implemented
English | [中文](2026-08-10-source-run-without-managed-installer.zh.md)
## Problem
A repository-owned source installer can provide a stable launcher, isolated staging worktrees, atomic upgrades, rollback storage, and shared maintenance workflows for personal customizations. It also makes the repository responsible for a second lifecycle beside the package manager: host dependency installation, credential prompting, checkout adoption, symlink ownership, staging branch coordination, upgrade recovery, and continued compatibility between the installer and bundled maintenance skills.
That lifecycle is not required to run or develop DeepSeek Harness from a source checkout. Maintaining it expands the supported filesystem and Git state space without improving the repository-native execution path.
## Decision
The repository supports source execution through its root `pnpm` scripts. The `dsh` entry in `package.json` runs `pnpm run build`, then launches `apps/cli/src/bin.ts` through `node --import tsx/esm`; build output remains visible before the CLI output. The package script forwards arguments and inherits the caller's environment, including `NODE_USE_ENV_PROXY=1` when a supporting Node version must honor `HTTP_PROXY` and `HTTPS_PROXY`. Users select Web with `pnpm dsh web` and headless execution with `pnpm dsh --profile headless "task"`. The independent ACP example remains available through `pnpm run demo:acp`.
The repository does not distribute a source installer, an installer test suite, or skills that assume a managed `current` symlink and timestamped staging worktrees. Users own source checkout placement, Git updates, and any launcher they create outside the repository.
## Alternatives considered
**Keep the installer but document `pnpm run` as another path.** This retains the managed launcher and rollback capability but keeps both lifecycle contracts active, including the installer tests and staging-aware skills.
**Keep generic customization and upstream-publication skills.** Their safety rules can apply beyond the staging layout, but the shipped workflows form one coupled maintenance system: customization discovers the installed staging checkout, upgrade performs the cutover, and upstream publication is selected from those personal changes. General Git contribution guidance already belongs to repository instructions and does not require product-bundled skills.
**Replace the installer with a smaller launcher-link script.** This reduces setup behavior but still makes the repository responsible for host PATH mutation and launcher ownership. Source scripts provide the entry points without that state.
## Consequences
Source users invoke repository scripts rather than an installed `dsh` command. The repository provides no atomic upgrade cutover or preserved staging rollback checkout, and it does not automate the integration or upstream publication of personal source modifications. A future distribution mechanism must justify its ownership of installation and upgrade state, define recovery behavior, and add tests and user documentation without making the source-run path depend on it. Any future publication workflow must isolate one approved feature and obtain explicit approval before its first push and draft PR.
Verification covers repository-wide references to the removed entry points, documentation links, generated third-party-notice freshness, the build-first `package.json` command, and a source CLI smoke through the exact `node --import tsx/esm` runtime vector.

# Agent Note: 无需托管安装器的源码运行
Status: implemented
[English](2026-08-10-source-run-without-managed-installer.md) | 中文
## 问题
仓库自带的源码安装器可以提供稳定的启动器、相互隔离的 staging worktree、原子升级、回滚存储,以及用于个人定制的共享维护工作流。与此同时,仓库还必须在包管理器之外负责第二套生命周期:安装宿主依赖、提示输入凭证、接管检出、管理符号链接归属、协调 staging 分支、处理升级恢复,以及持续保持安装器与随附维护 skill(技能)的兼容性。
从源码检出运行或开发 DeepSeek Harness 并不需要这套生命周期。维护它会扩大需要支持的文件系统和 Git 状态空间,却无法改进仓库原生的执行路径。
## 决策
仓库通过根目录的 `pnpm` 脚本支持从源码运行。`package.json` 中的 `dsh` 项先执行 `pnpm run build`,再通过 `node --import tsx/esm` 启动 `apps/cli/src/bin.ts`;构建输出会显示在 CLI(命令行界面)输出之前。该包脚本会转发参数并继承调用方环境;当支持环境代理的 Node 版本必须遵循 `HTTP_PROXY` 和 `HTTPS_PROXY` 时,调用方可设置 `NODE_USE_ENV_PROXY=1`。用户使用 `pnpm dsh web` 选择 Web,使用 `pnpm dsh --profile headless "task"` 选择无头执行。独立的 ACP(Agent Client Protocol)示例仍可通过 `pnpm run demo:acp` 运行。
仓库不分发源码安装器、安装器测试套件,也不分发依赖受管理的 `current` 符号链接和带时间戳 staging worktree 的 skill。源码检出的存放位置、Git 更新,以及用户在仓库外创建的任何启动器均由用户负责。
## 考虑过的备选方案
**保留安装器,但将 `pnpm run` 记作另一条路径。**这样可以保留受管理的启动器和回滚能力,但两套生命周期约定仍会同时生效,其中包括安装器测试和依赖 staging 布局的 skill。
**保留通用的定制与上游发布 skill。**其中的安全规则也能用于 staging 布局之外,但现有工作流共同构成了一套耦合的维护系统:定制工作流查找已安装的 staging 检出,升级工作流执行切换,上游发布工作流则从这些个人修改中选择发布内容。通用 Git 贡献指南已经属于仓库指令,无需以产品随附 skill 的形式提供。
**用更小的启动器链接脚本替换安装器。**这样可以简化设置过程,但仓库仍需负责修改宿主 PATH 和管理启动器归属。源码脚本无需引入这类状态即可提供入口点。
## 影响
源码用户通过仓库脚本运行程序,而非使用已安装的 `dsh` 命令。仓库不提供原子升级切换,也不保留 staging 回滚检出;仓库同样不会自动集成个人源码修改或将其发布到上游。未来的分发机制必须说明为何应由其管理安装和升级状态,定义恢复行为,并补充测试与用户文档,同时不得让源码运行路径依赖该机制。未来任何发布工作流都必须隔离出一项获批功能,并在首次推送和创建草稿 PR(Pull Request)前取得明确批准。
验证范围包括仓库内对已移除入口点的所有引用、文档链接、生成的第三方声明文件的新鲜度、`package.json` 中的先构建后启动命令,以及通过准确的 `node --import tsx/esm` 运行方式对源码 CLI 进行的冒烟测试。
