## Problem ## Problem
The harness spoke one shell dialect on every platform: `bash`. Windows hosts could run it only through WSL or Git-Bash shims, and the shipped `dsh-bash-local` executor is POSIX-only (`bash` hardcoded, process-group semantics POSIX). The Windows roadmap — defaulting hosts to `pwsh`, later pwsh TUI/GUI rendering — had no execution foundation: there was no PowerShell implementation of the bash executor seam and no model-facing tool that taught the PowerShell dialect. The bash tool itself is also far larger than a Windows-first profile needs: background tasks, sandbox escalation, and the persistent-PTY twin are all bash-shaped surface that a minimal `pwsh` tool should not carry.

The bash tool is also larger than a Windows-first profile strictly needs — the persistent-PTY twin in particular is bash-shaped surface the `pwsh` tool still does not carry. The original minimal profile also left out background tasks and sandbox escalation: background arrived with the [parity decision](2026-08-02-pwsh-tool-bash-parity.md), and the sandbox surface (denial rendering plus `sandbox_permissions` escalation) arrived with the [Windows ACL sandbox decision](2026-08-08-windows-acl-restricted-token-sandbox.md) — the minimal tool was sized for the danger-full-access Windows posture, and that premise ended when the sandbox PR re-enabled confinement and approval on Windows.
## Decision ## Decision
Two new packages under `packages/bash/`: Two new packages under `packages/bash/`:
- **`@deepseek-ai/dsh-pwsh-local`** — a local implementation of the `ctx.bash` executor seam over `ctx.subprocess`, mirroring `dsh-bash-local` call-for-call: `resolve()` defaults and caps from config, `run()` fuses the config-clamped timeout with the caller's signal through one deadline, `start()` returns a consuming background handle whose processes belong to the subprocess service. The command string rides as ONE argv element to `pwsh -NoLogo -NoProfile -NonInteractive -Command`, so PowerShell parses it and no shell-quoting layer exists. Executable resolution (`resolvePwshPath`) is a pure function of `(configured, env, platform)`: explicit config first, then Windows probes PowerShell 7's install, PATH entries (quotes stripped), and Windows PowerShell 5.1, else a bare `pwsh` via PATH. - **`@deepseek-ai/dsh-pwsh-local`** — a local implementation of the `ctx.bash` executor seam over `ctx.subprocess`, mirroring `dsh-bash-local` call-for-call: `resolve()` defaults and caps from config, `run()` fuses the config-clamped timeout with the caller's signal through one deadline, `start()` returns a consuming background handle whose processes belong to the subprocess service.

- **`@deepseek-ai/dsh-tool-pwsh`** — the model-facing tool over `ctx.bash`, PowerShell-dialect by contract, mirroring `dsh-tool-bash` call-for-call minus the sandbox surface: foreground and `run_in_background` execution through the generic task runtime, managed `DSH_*` environment through the shared [`dsh-bash-env`](../feature/2026-08-02-pwsh-tool-bash-parity.md) registry, and the bash marker/truncation rendering story (a clean exit produces no marker). The parity decision supersedes this note's minimal-profile tool description. - **`@deepseek-ai/dsh-tool-pwsh`** — the model-facing tool over `ctx.bash`, PowerShell-dialect by contract, mirroring `dsh-tool-bash` call-for-call: foreground and `run_in_background` execution through the generic task runtime, managed `DSH_*` environment through the shared [`dsh-bash-env`](../feature/2026-08-02-pwsh-tool-bash-parity.md) registry, the bash marker/truncation rendering story (a clean exit produces no marker), and — since the Windows ACL sandbox decision — the sandbox denial rendering and `sandbox_permissions` escalation surface, plus the Windows-specific ConstrainedLanguage and named-pipe contracts in the tool description. The parity decision supersedes this note's minimal-profile tool description.
Windows vitest coverage is deliberately NOT part of this change: the repo's Windows CI lane owns build/static gates, and unit coverage runs on Linux, where both packages' suites run against a real `pwsh` (preinstalled on the GitHub-hosted runners) or self-skip when absent. The vitest `windowsUnsupportedPackages` exclusion narrows from `packages/bash/*` to the bash-requiring packages so the pwsh suites can also run natively on Windows dev machines.

## Alternatives considered ## Alternatives considered
**Extend `dsh-bash-local` with a pwsh mode.** Rejected: the executor's identity is the shell it spawns; a second dialect inside one package doubles its config surface (`shell` switches) and its test matrix, and the two dialects' quirks (signal facts on Windows, quoting domains) belong to their own packages' documentation. **Extend `dsh-bash-local` with a pwsh mode.** Rejected: the executor's identity is the shell it spawns; a second dialect inside one package doubles its config surface (`shell` switches) and its test matrix, and the two dialects' quirks (signal facts on Windows, quoting domains) belong to their own packages' documentation.
**Extend `dsh-tool-bash` with a dialect parameter.** Rejected: the bash tool's background/sandbox surface is bash-shaped; a `pwsh` mode would either hide it (conditional schema churn) or inherit it (surface the minimal profile explicitly rejects). The minimal twin keeps the model contract honest. **Extend `dsh-tool-bash` with a dialect parameter.** Rejected: the model-visible contract is the dialect itself (paths, variables, exit facts differ), so a dialect parameter would either churn the schema conditionally or force one tool to teach two dialects; the separate twin keeps the model contract honest — and carries the shared surfaces (background, sandbox, rendering) by mirroring rather than by sharing an implementation.
**Wire the pwsh tool into the shipped CLI compositions now.** Rejected: mounting `tool-pwsh` + `pwsh-local` in `base.cordis.yml` would change the shipped roster before the Windows-default decision lands; this change ships the capability and its wiring points (`apps/cli` dependencies, tsconfig projects) without switching any default. **Wire the pwsh tool into the shipped CLI compositions now.** Rejected: mounting `tool-pwsh` + `pwsh-local` in `base.cordis.yml` would change the shipped roster before the Windows-default decision lands; this change ships the capability and its wiring points (`apps/cli` dependencies, tsconfig projects) without switching any default.

# Agent Note: Windows defaults to pwsh
Status: implemented
English | [中文](2026-08-01-windows-pwsh-default.zh.md)
## Problem
The harness's shipped execution profile is bash-first on every platform. Windows hosts must install a bash shim (WSL or Git-Bash) or fall back to the POSIX-only `dsh-bash-local` behavior (hardcoded `bash -c` argv, process-group semantics); the model-facing bash tool teaches the bash dialect. The Windows-native foundation shipped in the [pwsh executor and tool decision](2026-08-01-pwsh-tool-and-executor.md) — a PowerShell implementation of the `ctx.bash` seam and a parity `pwsh` tool — but shipped compositions still mounted the bash stack on Windows, so a Windows host without a shim could not run the shipped shell.
## Decision
Windows hosts booting a shipped profile (`dsh web`, `dsh --profile headless`, one-shot tasks) get the PowerShell stack by default; POSIX hosts are unchanged.
- **The platform layer is a data file, not a roster rewrite.** `@deepseek-ai/dsh-base` ships [`windows.cordis.patch.yml`](../../../../packages/bundle/base/windows.cordis.patch.yml) alongside its universal `cordis.patch.yml`: it disables `bash-sandbox`/`tool-bash` (the POSIX-only executor and its dialect tool) and inserts `pwsh-local`/`tool-pwsh`. Windows has no OS sandbox runner (landlock/bwrap/seatbelt are POSIX-only), so the layer drops the sandbox stack entirely — `sandbox`, `sandbox-policy`, and `fs-sandbox` are disabled and the unconfined `dsh-fs-local` provides `ctx.fs` — and degrades to danger-full-access: `permission`/`ui-permission` leave the roster (dsh-permission requires a confining executor — presets bundle a sandbox mode the unconfined executor cannot honor; see its constructor guard — and the client knob would advertise a boundary that does not exist), and the `approval` service is disabled — nothing in the Windows roster asks for approval, so the model is never told approval exists or that asks are auto-rejected. Keeping fs-only path rules would be theater: the unconfined shell can bypass them with one command, so the honest Windows posture is full access rather than a boundary only the fs tools pretend to enforce.
- **The launcher injects the layer by platform.** `apps/cli/src/windows-shell.ts` resolves it from the base bundle layer's `packageDir` between the bundle layers and the user layers on `win32` hosts, in every composition path (boot, config-only HMR recomposition, config dumps). Overriding the shipped default is a composition decision: a Windows host that prefers the bash stack — or confinement — re-enables the bash rows through its profile or home `cordis.patch.yml`. Custom profiles without the base bundle are skipped (they own their shell stack); a base bundle that ships no Windows shell patch fails loud.
- **Module resolution is restored for cold starts.** The profiles-rework CLI dropped the pwsh packages from `apps/cli`'s dependency closure, so `healProfilesModuleFallback` never linked them into `$DSH_HOME/profiles/node_modules` and a fresh Windows host could not resolve the inserted rows. `apps/cli` and `dsh-base` re-declare `dsh-pwsh-local`/`dsh-tool-pwsh`, and `dsh-base` also declares `dsh-fs-local`; the base bundle lists every row plugin as a dependency by house style.
The pwsh GUI rendering shipped earlier with the [pwsh UI presentation matches bash decision](2026-08-05-pwsh-ui-bash-parity.md); the [pwsh tool bash parity decision](2026-08-02-pwsh-tool-bash-parity.md) ships the tool's surface. Nothing in this decision changes POSIX behavior.
## Alternatives considered
**Default Windows to pwsh inside `dsh-bash-local` (one executor, dialect switch).** Rejected for the same reason the executor decision rejected a mode switch: the executor's identity is the shell it spawns, and platform-gated composition is a deployment choice, not an executor config.
**Ship the platform layer from `apps/cli` code instead of a bundle data file.** Rejected: the patch belongs next to the rows it replaces, in the bundle that owns them, so the shipped roster stays visible as composition data and dumps carry its provenance; the launcher contributes only the win32 gate.
**Keep `permission`/`ui-permission` on Windows.** Rejected: `dsh-permission` hard-requires `ctx.bash.sandboxMode` and fails loud at load over an unconfined executor; making it tolerate an unconfined shell would advertise presets the shell cannot honor.
**Keep fs path-rule confinement on Windows (`sandbox-policy` + `fs-sandbox` without OS runners).** Rejected: the shell is the model's primary tool and unconfined on Windows, so fs-only path rules are trivially bypassable and would overstate the boundary; the honest posture is full degradation to danger-full-access.
**Ship a `DSH_WINDOWS_SHELL` environment escape hatch.** Rejected: decisive behavior changes belong in composition config, which already overrides the platform layer row by id; a second override channel would split the single source of truth for roster decisions.
## Consequences
- A Windows host running a shipped `dsh` surface gets `pwsh` as its shell tool and PowerShell as the `ctx.bash` executor without configuration; `bash` is absent from the model-visible roster there (its tool row is disabled).
- Windows has no sandbox at all: the fs tools run unconfined (`dsh-fs-local`), the approval service is absent (nothing asks for approval, and the model is never told approval exists), and the permission switcher is gone. The model-visible posture is honest full access rather than a boundary the shell can bypass.
- POSIX hosts are unchanged: the platform layer never applies, and the bash stack remains the universal `cordis.patch.yml` rows.
- Windows hosts that prefer the bash stack (e.g. with WSL/Git-Bash on PATH) override the shipped default through their profile or home `cordis.patch.yml` — disabling `pwsh-local`/`tool-pwsh` and re-enabling `bash-sandbox`/`tool-bash` (both executors register the same `bash` service, so an incomplete recipe fails loud at load) — composition config is the one override channel.
## Verification
- Unit: `apps/cli/tests/windows-shell.spec.ts` pins the win32 default, the custom-profile skip, and the missing-patch failure with the platform injected, and composes the REAL shipped bundle layers (dsh-base + dsh-web-app resolved from the app installation) through the boot's patch algorithm to assert the win32 danger-full-access roster and the base-only-profile warning; `packages/bundle/base/tests/base.spec.ts` pins the shipped Windows patch file shape (disables, inserts, and the absent approval service).
- Keyless: a win32 `dsh --profile <name> --dump-config` shows the pwsh rows with `windows.cordis.patch.yml` provenance and the bash rows disabled; the POSIX dump (CI Linux) is unchanged.
- The real-composition smoke boots the web profile on win32 with the pwsh stack mounted (the exact roster this note describes).

# Agent Note: Windows 默认改用 pwsh

## 问题
harness 交付的执行画像在每个平台都是 bash 优先。Windows 主机必须安装 bash 垫片（WSL 或 Git-Bash），或退回到仅 POSIX 的 `dsh-bash-local` 行为（硬编码 `bash -c` argv、进程组语义）；面向模型的 bash 工具教的是 bash 方言。Windows 原生基础已随 [pwsh 执行器与工具决策](2026-08-01-pwsh-tool-and-executor.md) 交付——`ctx.bash` seam 的 PowerShell 实现与对等的 `pwsh` 工具——但交付组合在 Windows 上仍然挂载 bash 栈，没有垫片的 Windows 主机跑不了交付的 shell。
## 决策
启动交付 profile（`dsh web`、`dsh --profile headless`、一次性任务）的 Windows 主机默认获得 PowerShell 栈；POSIX 主机不变。
- **平台层是数据文件，不是清单重写。** `@deepseek-ai/dsh-base` 随通用 `cordis.patch.yml` 一起交付 [`windows.cordis.patch.yml`](../../../../packages/bundle/base/windows.cordis.patch.yml)：它禁用 `bash-sandbox`/`tool-bash`（仅 POSIX 的执行器及其方言工具）并插入 `pwsh-local`/`tool-pwsh`。Windows 上没有 OS 级 sandbox runner（landlock/bwrap/seatbelt 均为 POSIX 专属），因此该层整体移除 sandbox 栈——`sandbox`、`sandbox-policy`、`fs-sandbox` 被禁用，由不限权的 `dsh-fs-local` 提供 `ctx.fs`——并完全退化为 danger-full-access：`permission`/`ui-permission` 离开清单（dsh-permission 要求有限权能力的执行器——preset 捆绑的是无限制执行器无法兑现的 sandbox 模式；见其构造函数守卫——客户端旋钮会宣传一个并不存在的边界），`approval` 服务也被禁用——Windows 清单里没有任何动作需要审批，模型也不会被告知"审批存在"或"请求会被自动拒绝"。保留仅限 fs 的路径规则是摆设：不限权的 shell 一条命令即可绕过，因此诚实的 Windows 姿态是全权访问，而不是一个只有 fs 工具假装执行的边界。
- **启动器按平台注入该层。** `apps/cli/src/windows-shell.ts` 在 `win32` 主机上从 base bundle 层的 `packageDir` 解析它，置于 bundle 层与用户层之间，覆盖所有组合路径（启动、config-only HMR 重组合、配置转储）。覆盖交付默认是组合决策：偏好 bash 栈（或偏好有限权）的 Windows 主机通过其 profile 或 home 的 `cordis.patch.yml` 重新启用 bash 行。未挂 base bundle 的自定义 profile 被跳过（它们自己拥有 shell 栈）；base bundle 缺 `windows.cordis.patch.yml` 时 fail loud。
- **冷启动的模块解析已恢复。** profiles 重构把 pwsh 包从 `apps/cli` 的依赖闭包中删掉了，`healProfilesModuleFallback` 因此从未把它们链接进 `$DSH_HOME/profiles/node_modules`，新 Windows 主机解析不到插入的行。`apps/cli` 与 `dsh-base` 重新声明 `dsh-pwsh-local`/`dsh-tool-pwsh`，`dsh-base` 还声明 `dsh-fs-local`；按仓库惯例，base bundle 把每个行插件都列为依赖。
pwsh GUI 渲染已随 [pwsh UI 呈现与 bash 对齐决策](2026-08-05-pwsh-ui-bash-parity.md) 先行交付；[pwsh 工具与 bash 对齐决策](2026-08-02-pwsh-tool-bash-parity.md) 交付了工具表面。本决策不改变任何 POSIX 行为。
## 备选方案
**在 `dsh-bash-local` 内部让 Windows 默认 pwsh（一个执行器，方言开关）。** 否决，理由与执行器决策否决模式开关相同：执行器的身份就是它 spawn 的 shell，而按平台门控的组合是部署选择，不是执行器配置。
**从 `apps/cli` 代码而非 bundle 数据文件交付平台层。** 否决：patch 应放在它替换的行旁边、属于拥有这些行的 bundle，让交付清单作为组合数据保持可见、转储带有出处；启动器只贡献 win32 门控。
**在 Windows 上保留 `permission`/`ui-permission`。** 否决：`dsh-permission` 硬性要求 `ctx.bash.sandboxMode`，在无限制执行器上加载即 fail loud；让它容忍无限制 shell 会宣传 shell 无法兑现的 preset。
**在 Windows 上保留 fs 路径规则限制（无 OS runner 的 `sandbox-policy` + `fs-sandbox`）。** 否决：shell 是模型的主工具且在 Windows 上不限权，仅限 fs 的路径规则一行命令即可绕过，会夸大边界；诚实的姿态是完全退化到 danger-full-access。
**交付 `DSH_WINDOWS_SHELL` 环境变量逃生门。** 否决：决定性的行为变更应集中在组合配置中，而组合配置已能按行 id 覆盖平台层；第二条覆盖通道会分裂清单决策的单一事实来源。
## 后果
- 运行交付版 `dsh` 表面的 Windows 主机无需配置即获得 `pwsh` 作为 shell 工具、PowerShell 作为 `ctx.bash` 执行器；那里的模型可见清单中没有 `bash`（其工具行被禁用）。
- Windows 上没有任何沙箱：fs 工具不限权运行（`dsh-fs-local`）、`approval` 服务不存在（没有任何动作需要审批，模型也不会被告知审批存在）、权限切换器消失。模型可见的姿态是诚实的全权访问，而不是一个 shell 可以绕过的边界。
- POSIX 主机不变：平台层永不生效，bash 栈仍是通用 `cordis.patch.yml` 的行。
- 偏好 bash 栈的 Windows 主机（例如 PATH 上有 WSL/Git-Bash 时）通过其 profile 或 home 的 `cordis.patch.yml` 覆盖交付默认——禁用 `pwsh-local`/`tool-pwsh` 并重新启用 `bash-sandbox`/`tool-bash`（两个执行器注册同一个 `bash` 服务，配方不完整会在加载时 fail loud）——组合配置是唯一的覆盖通道。
## 验证
- 单元：`apps/cli/tests/windows-shell.spec.ts` 以平台注入固定 win32 默认、自定义 profile 跳过与缺文件失败，并通过启动所用的 patch 算法组合真实交付的 bundle 层（从应用安装解析的 dsh-base + dsh-web-app）断言 win32 danger-full-access 清单与 base-only profile 警告；`packages/bundle/base/tests/base.spec.ts` 固定交付的 Windows patch 文件形状（禁用、插入与缺席的 approval 服务）。
- Keyless：win32 上的 `dsh --profile <name> --dump-config` 显示带 `windows.cordis.patch.yml` 出处的 pwsh 行、被禁用的 bash 行；POSIX 转储（CI Linux）不变。
- 真实组合冒烟在 win32 上启动 web profile，pwsh 栈挂载成功（即本笔记描述的确切清单）。

# Agent Note: Windows sandbox rung: raw ACL restricted tokens over mxc and AppContainer
Status: implemented
English | [中文](2026-08-08-windows-acl-restricted-token-sandbox.zh.md)
## Problem
The [sandbox decision](2026-07-06-sandbox.md) leaves `PLATFORM_CHAINS.win32` empty, so shipped Windows profiles degrade to danger-full-access because no confining executor exists. The win32 rung must confine the two file-effect modes the sandbox vocabulary promises — `read-only` (zero writes) and `workspace-write` (writes under the workspace root plus a backend-defined temp area) — while leaving reads, network, and process visibility alone, because every mode permits reading.
## Decision
Implement the rung directly on the raw ACL mechanism: duplicate the caller's token into a `WRITE_RESTRICTED` token (`CreateRestrictedToken` with `WRITE_RESTRICTED` + `DISABLE_MAX_PRIVILEGE` + `LUA_TOKEN`) whose restricting SIDs include a write SID (`S-1-4-x-y`); the write SID's Write ACEs on the workspace and temp roots are the entire write allowlist, because `WRITE_RESTRICTED` intersects write accesses only and reads keep the caller's full ambient access. The mechanism is the one huoyaoyuan/windows-acl-restrict-poc (`10e4dfb`) demonstrates; this port checks every API call and fails closed (the POC fail-opened on every ignored return value). The write SID is the PER-WORKSPACE identity, derived deterministically from the canonical workspace path (`workspaceWriteSid` — sha256 → `S-1-4-x-y`) and stored NOWHERE: the workspace-root ACE therefore materializes once per workspace per machine — the standing ACE is the cross-session reuse cache, and every later provision hits the exact-ACE skip (idempotent re-grant skips the eager full-tree re-propagation — no garbage collection) — instead of once per session, which is what the earlier per-session random SID paid a full tree propagation per session for. The seam derives the session's PRIVATE temp subdirectory from the session id + workspace (sha256, 16 hex — stored nowhere, so no tamper surface exists) and creates it exclusively; it is removed on provider dispose, and a crash leaves it as `%TEMP%` litter whose next resume fails loudly at the exclusive creation until temp hygiene reclaims it. The seam materializes the workspace ACE STANDING (never revoked — the cache) and the temp ACE REVOCABLY (revoked on provider dispose, so an inheritable ACE never outlives its session's temp directory on the ambient temp root). The token's restricting list is the keep-alive group plus the write SID only under workspace-write: read-only = [logon SID, Everyone] and workspace-write = [logon SID, Everyone, write SID]. The keep-alive invariants are logon SID + Everyone (early DLL init dies with 0xC0000142 and CNG crashes pwsh with 0xE0434352 without them). Read-only carries no write SID: a standing grant ACE from an earlier workspace-write period stays INERT (the pass-2 check grants only what the list carries, so read-only remains strictly zero-grant across a `/permission` downgrade or a crash-resumed session, while the standing ACE keeps the re-upgrade free). Authenticated Users is absent from BOTH lists — the WMI namespace security check fails (0x80041003), so CIM is unavailable in every confined mode, and the C:\-root tree-creation escape (standing `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACEs) is closed in both; INTERACTIVE/LOCAL are likewise absent from both (the Public tree writes are denied — pinned by the runner's Public-probe regression). Workspace-write children see a PRIVATE per-session temp subdirectory (`<temp>\dsh-<16 hex>` derived from the session id + workspace — created exclusively, reparse points rejected, removed on provider dispose — TMP/TEMP rewritten by the runner — bwrap `--tmpfs /tmp` semantics). The restricted token's DEFAULT DACL is extended with a full-access write-SID ACE (`SetTokenInformation(TokenDefaultDacl)`): new objects created without an explicit security descriptor (anonymous pipes — CreatePipe, sync objects) then carry a restricting-SID ACE and pass the write pass-2 check at creation; NAMED pipes are exempt — their default security descriptor is the Win32 layer's user-mode default SD template (built by KernelBase — owner/SYSTEM/Admins full, Everyone/ANONYMOUS read-only), which the token cannot influence, so piped stdio capture stays denied for confined grandchildren (the POC-documented boundary, pinned by the runner suite). It ships as [`@deepseek-ai/dsh-sandbox-windows-acl`](../../../../packages/sandbox/sandbox-windows-acl/README.md) (backend plus the `./runner` argv-prefix entry), the `win32` chain rung of [`dsh-sandbox-local`](../../../../packages/sandbox/sandbox-local/README.md), and [`@deepseek-ai/dsh-pwsh-sandbox`](../../../../packages/bash/pwsh-sandbox/README.md) as the confining executor; the Windows platform layer re-enables the full permission surface (sandbox/sandbox-policy/permission/approval/fs-sandbox) over the confined pwsh stack.
## How the restriction works (why no new identity)
The identity routes restrict by *who* runs the child; this rung restricts by *token derivation*. An identity route (landstrip's restricted-user, AppContainer) runs the child under a fresh account or container SID that starts with zero ACEs on the host's files — everything, reads included, defaults to denied, and every path the child may touch must then be opened back up by writing ACEs for that identity: the wholesale DACL mutation that disqualified both alternatives. The restricted token keeps the caller's own SID and logon session: [`CreateRestrictedToken`](https://learn.microsoft.com/en-us/windows/win32/api/securitybaseapi/nf-securitybaseapi-createrestrictedtoken) derives a token that adds the restricting SIDs and the `WRITE_RESTRICTED` flag, so Windows performs the access check twice — once against the normal SIDs, once against the restricting SIDs — and grants write-class access only where both checks pass. Reads pass on the normal check alone (the caller's SIDs already carry read access everywhere the caller can read), which is why this rung needs no read grants and no new account; writes must additionally clear the orphan-SID check, which only the workspace and temp ACEs satisfy. `DISABLE_MAX_PRIVILEGE | LUA_TOKEN` synthesize the limited-user effect of a fresh account token-side, so even an elevated caller derives a filtered token. The same primitive could restrict reads (`SidsToDisable` turning SIDs deny-only), but a read-restricted token would need per-path read grants — reintroducing exactly the cost the identity routes pay — and the sandbox vocabulary never requires read confinement.
## Alternatives considered
### Why not mxc (Microsoft xContainer)?
Two disqualifiers. First, the OS floor is too new: the [mxc OS-version policy](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md) sets the product floor at Windows 11 24H2 (build 26100), and the BaseContainer tier (T1, `Experimental_CreateProcessInSandbox`) exists only on 25H2+ (build 26600+) with the OS feature enabled — on every supported release at or below 25H2 the filesystem policy falls back to T3, AppContainer plus host-side DACL ACE augmentation. Second, supporting arbitrary-path reads under either tier means granting read access by writing ACLs over every path the child may read: a model that reads the whole workspace and arbitrary files would require wholesale host DACL mutation — a standing side effect and a cost a write-only restriction does not need.
### Why not AppContainer?
An AppContainer token carries no ambient read access: every readable path must be pre-granted through capabilities or explicit ACEs, so arbitrary-path reads — the harness's read model — are unsupported without the same wholesale grants. The restricted token needs no read grants at all: it intersects write access only.
### Why not landstrip?
The [landstrip evaluation](../../rejected/feature/2026-07-26-evaluate-landstrip-for-windows-sandbox-rung.md) was rejected before implementation (not battle-tested; the in-house launcher plan won), and its Windows backend is AppContainer-shaped, inheriting the same arbitrary-read problem.
## Consequences
Bought: write-only confinement with no new OS floor (`CreateRestrictedToken` predates the mxc releases by two decades), reads/network/process visibility untouched exactly as the mode vocabulary requires, and fail-closed errors carrying the API name and the exact Win32 code. Cost: no read-side or network isolation; console isolation unavailable (hidden-console children die with `STATUS_DLL_INIT_FAILED`; children share the host console); standing ACE mutations on the granted roots (caller-owned directories; workspace ACEs stand forever by design — the reuse cache, invisible residue when a workspace is renamed — temp ACEs revoked by provider dispose together with the derived private temp directory — a crash leaves both behind and the next resume fails loudly at the exclusive creation until temp hygiene reclaims the directory); grant materialization is an EAGER full-tree propagation (`SetNamedSecurityInfoW` walks every descendant immediately — tens of seconds on large workspaces), paid once per workspace per machine by the per-workspace identity; CIM is unavailable in BOTH confined modes (AuthUsers dropped from both lists — the WMI namespace security check fails, and `Get-ComputerInfo` silently returns incomplete results) as the price of closing the C:\-root tree-creation escape in both; FAT-class (non-ACL) targets outside the granted roots remain writable under both modes (no security descriptors to intersect — a legacy residue treated as unsupported, warn-only, documented in the README); NULL-DACL directories are not identity-preserving under a grant+revoke round-trip (documented edge, the POC shares it); `whoami` and token-inspection cmdlets fail under the restricted token (diagnostic noise, documented); and BOTH confined modes run `pwsh` in ConstrainedLanguage mode — the restricted token trips PowerShell's lockdown detection, so `Add-Type`, non-core .NET statics (`[System.IO.*]::`, `[math]::`), COM objects, and reflection fail with "only core types" errors while `-f` formatting, property access, and core cmdlets/types keep working, and the language mode cannot be lifted back to FullLanguage from inside — taught to the model in the pwsh tool description and documented in the package README's Known Limitations; BOTH confined modes also deny named-pipe opens — libuv's piped-stdio spawns fail with EPERM (the POC-documented "no output redirection" boundary; inherited/ignored stdio and anonymous pipes work) — documented in the package README's Known Limitations and taught to the model in the pwsh tool description.
## Testing
The product-visible Windows roster flip is win32-only, so the keyless snapshot fixtures — which must replay on macOS/Linux — cannot cover it; the bundle composition specs ([`base.spec.ts`](../../../../packages/bundle/base/tests/base.spec.ts), [`windows-shell.spec.ts`](../../../../apps/cli/tests/windows-shell.spec.ts)) plus the win32 real-runner suites (`packages/sandbox/sandbox-windows-acl/tests/`, `packages/bash/pwsh-sandbox/tests/`) are the substitute evidence, and the CI Windows lane owns the assembled signal. The grant machinery is pinned cross-platform by `packages/sandbox/sandbox-local/tests/acl-grants.spec.ts` (the derived private-temp identity — deterministic per session + workspace, distinct across sessions — one-shot materialization, exclusive temp creation with reparse-point rejection and self-cleanup on failure, clean-restart re-grant of the same derived directory, the standing-vs-revocable lifecycle across dispose and the mode-switch cycle, and the derived-SID argv contract — with the Win32 surface mocked) and on win32 by `workspace-sid.spec.ts` (derivation determinism/shape/distinctness), `grant.spec.ts` (real-DACL materialization: revocable paths revoke on dispose, standing paths survive it), the `acl.spec.ts` idempotent-grant fast-path and standing-ACE-after-dispose contract, the `failure-paths.spec.ts` suspension-orphan regression (AssignProcessToJobObject failure terminates the child), and the `runner.spec.ts` `--write-sid` contract (caller-owned grants, private temp subdir through TMP/TEMP, both-mode CIM-denial probes, the mode-downgrade regression — a standing grant ACE is inert under read-only and effective again on re-upgrade — the ambient-writable Public-probe regression (a C:\Users\Public subdirectory write is denied under both modes), and the ConstrainedLanguage pins in both modes, plus the grandchild-stdio matrix pins — inherited/ignored stdio spawns succeed while piped capture is DENIED in both modes). The runner-failure classification is exit-gated on 127 (a confined command that merely prints the `windows-acl-run:` signature on a non-127 exit is never misclassified as "the command did not run" — pinned in the pwsh-sandbox helper suite).

# Agent Note: Windows sandbox rung: raw ACL restricted tokens over mxc and AppContainer
Status: implemented
[English](2026-08-08-windows-acl-restricted-token-sandbox.md) | 中文
## Problem
[沙盒决策](2026-07-06-sandbox.md)把 `PLATFORM_CHAINS.win32` 留空，交付的 Windows profile 因为没有可用的隔离执行器而退化为 danger-full-access。win32 档必须实现沙盒词汇表承诺的两个文件效果模式——`read-only`（零写入）与 `workspace-write`（仅工作区根目录加后端定义的临时区域可写）——同时保持读、网络与进程可见性不受影响，因为所有模式都允许读取。
## Decision
直接基于原始 ACL 机制实现该档：把调用者令牌复制为 `WRITE_RESTRICTED` 受限令牌（`CreateRestrictedToken`，`WRITE_RESTRICTED` + `DISABLE_MAX_PRIVILEGE` + `LUA_TOKEN`），其 restricting SIDs 中包含写入 SID（`S-1-4-x-y`）；工作区与临时目录上写入 SID 的 Write ACE 就是全部写入白名单，因为 `WRITE_RESTRICTED` 只对写访问做交集检查，读保持调用者的完整环境访问。该机制来自 huoyaoyuan/windows-acl-restrict-poc（`10e4dfb`）的演示；本移植检查每一个 API 调用并 fail-closed（POC 因忽略返回值而 fail-open）。写入 SID 是**按工作区**的身份，由规范工作区路径确定性派生（`workspaceWriteSid`——sha256 → `S-1-4-x-y`），且**任何地方都不存储**：工作区根目录 ACE 因此每台机器每个工作区只物化一次——常驻 ACE 就是跨会话复用缓存，此后每次供给都命中精确 ACE 跳过（幂等重授权跳过急切的全树重传播——不做垃圾回收）——而不是每会话一次，这正是先前每会话随机 SID 每个会话都要付一次全树传播的代价。seam 从会话 id + 工作区派生会话的**私有**临时子目录（sha256、16 位 hex——任何地方都不存储，因此不存在篡改面）并独占创建；它在提供方 dispose 时移除，崩溃则把它留作 `%TEMP%` 垃圾，其下一次恢复会在独占创建处大声失败，直到临时目录卫生机制将其回收。seam 把工作区 ACE **常驻**物化（绝不撤销——就是缓存），把临时 ACE **可回收**物化（提供方 dispose（资源释放）时撤销，因此可继承 ACE 不会在环境临时根目录上比其会话的临时目录活得更久）。令牌的 restricting list 是保活组加上仅 workspace-write 下的写入 SID：read-only = [登录 SID、Everyone]，workspace-write = [登录 SID、Everyone、写入 SID]。保活不变式是登录 SID + Everyone（没有它们，早期 DLL init 会以 0xC0000142 死亡，CNG 会让 pwsh 以 0xE0434352 崩溃）。Read-only 不含写入 SID：先前 workspace-write 时期留下的常驻授权 ACE 保持**失效**（pass-2 检查只授予列表所携带的内容，因此 read-only 在 `/permission` 降级或崩溃后恢复的会话中始终保持严格零授权，而常驻 ACE 让重新升级保持零成本）。Authenticated Users 在**两种**列表中都缺席——WMI namespace 安全校验失败（0x80041003），因此 CIM 在每一种受限模式下都不可用，且 C:\-root 建树逃逸（驻留的 `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACE）在两种模式下都被关闭；INTERACTIVE/LOCAL 同样在两种列表中都缺席（Public 树的写入被拒绝——由 runner 的 Public-probe 回归钉住）。Workspace-write 子进程看到的是私有的每会话临时子目录（`<temp>\dsh-<16 hex>`——由会话 id + 工作区派生、独占创建、拒绝 reparse point、提供方 dispose 时移除——TMP/TEMP 由 runner 重写——bwrap `--tmpfs /tmp` 语义）。受限令牌的**默认 DACL** 被扩展一条写入 SID 全权 ACE（`SetTokenInformation(TokenDefaultDacl)`）：此后不带显式安全描述符创建的新对象（匿名管道——CreatePipe、同步对象）自带 restricting SID ACE，创建时的写 pass-2 检查通过；**named pipe 例外**——其默认安全描述符是 Win32 层在用户态安装的默认 SD 模板（由 KernelBase 构建——owner/SYSTEM/Admins 全权、Everyone/ANONYMOUS 只读），令牌无法影响，因此受限孙进程的管道 stdio 捕获保持拒绝（POC 记载的边界，由 runner 套件钉住）。它以 [`@deepseek-ai/dsh-sandbox-windows-acl`](../../../../packages/sandbox/sandbox-windows-acl/README.md)（后端加 `./runner` argv 前缀入口）、[`dsh-sandbox-local`](../../../../packages/sandbox/sandbox-local/README.md) 的 `win32` 链档、以及作为隔离执行器的 [`@deepseek-ai/dsh-pwsh-sandbox`](../../../../packages/bash/pwsh-sandbox/README.md) 交付；Windows 平台层在受限 pwsh 栈之上重新启用完整权限面（sandbox/sandbox-policy/permission/approval/fs-sandbox）。
## How the restriction works (why no new identity)
身份路线靠"**谁**在跑子进程"来限制，本档靠"令牌派生"来限制。身份路线（landstrip 的 restricted-user、AppContainer）用全新账户或容器 SID 运行子进程，该身份在宿主的文件上从零条 ACE 开始——一切访问（包括读）默认拒绝，子进程要碰的每条路径都必须事后为那个身份补写 ACE 才能放行：这正是让两个备选方案出局的全盘 DACL 改造。受限令牌保留调用者自己的 SID 与 logon session：[`CreateRestrictedToken`](https://learn.microsoft.com/en-us/windows/win32/api/securitybaseapi/nf-securitybaseapi-createrestrictedtoken) 派生一个加入 restricting SIDs 与 `WRITE_RESTRICTED` 标志的令牌，于是 Windows 做两次访问检查——一次按正常 SID，一次按 restricting SIDs——只有两次都放行，写类访问才被授予。读只凭正常检查即可通过（调用者的 SID 在其可读范围内本来就携带读权限），所以本档不需要任何读授权、也不需要新账户；写还必须额外通过孤儿 SID 检查，而只有工作区与临时目录的 ACE 能满足它。`DISABLE_MAX_PRIVILEGE | LUA_TOKEN` 在令牌侧合成了新账户的受限用户效果，即使提升过的调用者派生的也是过滤令牌。同一原语其实也能限制读（`SidsToDisable` 把 SID 变为 deny-only），但受限读的令牌需要逐路径的读授权——恰好重新引入身份路线付出的代价——而沙盒词汇表从不要求读隔离。
## Alternatives considered
### 为什么不选 mxc（Microsoft xContainer）？
两个否决理由。其一，OS 版本要求太新：[mxc 的 OS 版本支持文档](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md)把产品下限设在 Windows 11 24H2（build 26100），而 BaseContainer 档（T1，`Experimental_CreateProcessInSandbox`）只在 25H2+（build 26600+）且启用 OS feature 时存在——在 25H2 及以下的所有受支持版本上，文件系统策略都会回退到 T3，即 AppContainer 加宿主侧 DACL ACE 改造。其二，在任一档下支持任意路径读都意味着要为子进程可读的每个路径写 ACL 授予读权限：模型要读整个工作区和任意文件，就需要全盘改写宿主 DACL——对只做写限制的需求而言，这是不必要的驻留副作用与代价。
### 为什么不选 AppContainer？
AppContainer 令牌没有环境读访问：每个可读路径都必须预先通过 capability 或显式 ACE 授予，因此任意路径读——harness 的读模型——在不做同样的全盘授予时无法支持。受限令牌完全不需要读授予：它只对写访问做交集。
### 为什么不选 landstrip？
[landstrip 评估](../../rejected/feature/2026-07-26-evaluate-landstrip-for-windows-sandbox-rung.md)在实现前已被否决（未经实战检验；自建 launcher 方案胜出），且其 Windows 后端是 AppContainer 形态，继承同样的任意路径读问题。
## Consequences
所得：仅写隔离、不引入新的 OS 版本下限（`CreateRestrictedToken` 比 mxc 的版本早二十年）、读/网络/进程可见性完全不受影响（与模式词汇表一致）、fail-closed 错误携带 API 名与精确 Win32 错误码。所失：无读侧或网络隔离；控制台隔离不可用（隐藏控制台子进程以 `STATUS_DLL_INIT_FAILED` 死亡；子进程共享宿主控制台）；被授权根目录上有驻留 ACE 改动（目录须为调用者所有；工作区 ACE 按设计永久常驻——复用缓存，工作区改名时成为不可见残留——临时 ACE 由提供方 dispose 连同派生的私有临时目录一起回收——崩溃会把两者都留下，下一次恢复会在独占创建处大声失败，直到临时目录卫生回收该目录）；授权物化是急切的全树传播（`SetNamedSecurityInfoW` 立即遍历每个后代——在大型工作区上耗时数十秒），因按工作区身份，每台机器每个工作区只付一次；CIM 在**两种**受限模式下都不可用（AuthUsers 从两种列表中被移除——WMI namespace 安全校验失败，`Get-ComputerInfo` 静默返回不完整结果），作为关闭两种模式下 C:\-root 建树逃逸的代价；位于被授权根目录之外的 FAT 类（无 ACL）目标在两种模式下仍可写（没有可做交集的安全描述符——作为历史残留处理：不支持、仅警告、已在 README 中记录）；NULL DACL 目录在 grant+revoke 往返下不保持身份（记录在案的边角，POC 亦有此行为）；`whoami` 与令牌检查 cmdlet 在受限令牌下失败（诊断噪音，已记录）；且**两种**受限模式都以 ConstrainedLanguage 模式运行 `pwsh`——受限令牌触发 PowerShell 的锁定检测，因此 `Add-Type`、非核心 .NET 静态调用（`[System.IO.*]::`、`[math]::`）、COM 对象与反射都会以“only core types”错误失败，而 `-f` 格式化、属性访问与核心 cmdlet/类型继续工作，语言模式也无法从内部提升回 FullLanguage——已在 pwsh 工具描述中教给模型，并记录在包 README 的 Known Limitations 中；**两种**受限模式同样拒绝 named-pipe 打开——libuv 的管道 stdio spawn 以 EPERM 失败（POC 记载的“无法重定向输出”边界；继承/忽略的 stdio 与匿名管道可用）——记录在包 README 的 Known Limitations 中，并在 pwsh 工具描述中教给模型。
## Testing
产品可见的 Windows 阵容切换仅存在于 win32，而 keyless 快照夹具必须在 macOS/Linux 上可重放，因此无法覆盖它；替代证据是 bundle 组合 spec（[`base.spec.ts`](../../../../packages/bundle/base/tests/base.spec.ts)、[`windows-shell.spec.ts`](../../../../apps/cli/tests/windows-shell.spec.ts)）加上 win32 真实 runner 套件（`packages/sandbox/sandbox-windows-acl/tests/`、`packages/bash/pwsh-sandbox/tests/`），组装态信号由 CI 的 Windows lane 负责。授权机制在跨平台侧由 `packages/sandbox/sandbox-local/tests/acl-grants.spec.ts` 钉住（派生的私有临时身份——按会话 + 工作区确定性、跨会话相异——一次性物化、独占临时目录创建并拒绝 reparse point、失败时自我清理、干净重启时对同一派生目录的重新授权、dispose 与模式切换循环中的常驻/可回收生命周期，以及派生 SID 的 argv 契约——mock 掉 Win32 表面），win32 侧由 `workspace-sid.spec.ts`（派生的确定性/形态/相异性）、`grant.spec.ts`（真实 DACL 物化：可回收路径在 dispose 时撤销、常驻路径存活）、`acl.spec.ts` 的幂等授权快速路径与 dispose 后常驻 ACE 契约、`failure-paths.spec.ts` 的 suspension-orphan 回归（AssignProcessToJobObject 失败会终止子进程）与 `runner.spec.ts` 的 `--write-sid` 契约（调用者所有目录的授权、经 TMP/TEMP 的私有临时子目录、两种模式下的 CIM 拒绝探针、模式降级回归——驻留授权 ACE 在 read-only 下失效并在重新升级后再度生效——环境可写 Public-probe 回归（对 C:\Users\Public 子目录的写入在两种模式下都会被拒绝），以及两种模式下对 ConstrainedLanguage 的钉定，加上孙进程 stdio 矩阵钉定——继承/忽略的 stdio spawn 成功，而管道捕获在两种模式下都被**拒绝**）钉住。runner 失败分类以 127 退出码为门槛（受限命令仅仅在非 127 退出时打印 `windows-acl-run:` 签名，也绝不会被误分类为"命令未运行"——由 pwsh-sandbox helper 套件钉住）。

# Agent Note: Windows defaults to pwsh (roadmap)
Status: proposed
English | [中文](2026-08-01-windows-pwsh-default.zh.md)
## Problem
The harness's shipped execution profile is bash-first on every platform. Windows hosts must install a bash shim (WSL or Git-Bash) or fall back to the POSIX-only `dsh-bash-local` behavior; the model-facing bash tool teaches the bash dialect, and the TUI/Web surfaces render terminal output in bash-shaped expectations. The first Windows-native foundation shipped in the [pwsh executor and tool decision](../../implemented/feature/2026-08-01-pwsh-tool-and-executor.md): a PowerShell implementation of the `ctx.bash` seam and a parity `pwsh` tool — but nothing yet defaults Windows hosts to them.
## Proposal
Two follow-up stages, each independently shippable. The bash-tool parity twin shipped with the [pwsh tool bash parity decision](../../implemented/feature/2026-08-02-pwsh-tool-bash-parity.md): `tool-pwsh` now mirrors `tool-bash` for foreground and background work minus the sandbox surface, shares the `DSH_*` environment through `dsh-bash-env`, and carries a keyless application snapshot of its assembled surface.
1. **Windows default composition** — the shipped CLI compositions mount `dsh-pwsh-local` as the `ctx.bash` executor and `dsh-tool-pwsh` as the model-facing shell tool on Windows hosts (bash unmounted there), while POSIX hosts keep the bash stack. This is a composition/roster decision in `base.cordis.yml` and the surface overlays, gated by platform; it makes the shipped Windows experience PowerShell-native end to end.
2. **pwsh GUI rendering** — the Web surface renders pwsh calls with the bash-shaped terminal presentation (terminal card with exit-status pill), the counterpart of the bash terminal cards. Shipped in the [pwsh UI presentation matches bash decision](../../implemented/feature/2026-08-05-pwsh-ui-bash-parity.md) with a keyless web lane; the TUI was removed, so no terminal twin remains. A PowerShell-aware presentation beyond bash parity (native path display, `$env:` facts) remains unclaimed.
The stages are ordered by dependency only where one exists: the rendering stage shipped first with the [pwsh UI presentation matches bash decision](../../implemented/feature/2026-08-05-pwsh-ui-bash-parity.md) because it is platform-independent and its keyless web lane runs on any host, while the Windows default composition remains the only unshipped stage. Nothing in this proposal changes POSIX behavior.
## Alternatives considered
**Default Windows to pwsh inside `dsh-bash-local` (one executor, dialect switch).** Rejected for the same reason the executor decision rejected a mode switch: the executor's identity is the shell it spawns, and platform-gated composition is a deployment choice, not an executor config.
**Ship the Windows default in the same change as the executor/tool.** Rejected: the roster change needs its own evidence (what breaks when the shipped Windows tree stops mounting bash, which tools depend on bash semantics), and it belongs to a composition decision with the approval/PTY surface visible.
**Keep bash on Windows via a shim and skip PowerShell defaults.** Rejected: it perpetuates the install-tax and the dialect mismatch the roadmap exists to remove; the shim is a deployment requirement, not a product behavior.
## Acceptance criteria
- A Windows host running the shipped `dsh` TUI/Web gets `pwsh` as its shell tool and PowerShell as the `ctx.bash` executor without configuration, and `bash` is absent from the model-visible roster there.
- POSIX hosts are byte-for-byte unaffected (same roster, same executor).
- The shipped-composition e2es assert the platform-gated roster on both families.
- Stage 1 lands with the keyless pwsh-tool snapshot already in place from the parity change; stage 2 landed with the web `pwsh-terminal` rendering lane (the TUI's removal left no terminal surface to snapshot).
## Risks
- **Bash-dependent composition rows** — any shipped plugin that assumes `bash` semantics (hook bridges executing shell hooks, workspace tooling) must be audited per stage; the audit may force a staged rollout rather than one switch.
- **Windows CI coverage gap** — unit coverage runs on Linux; Windows-only regressions in the pwsh stack surface through the Windows build/static lane and e2es, which must be extended per stage rather than assumed.
- **Rendering conventions** — the bash-shaped terminal twin shipped with the Web lane; a PowerShell-aware presentation beyond bash parity (native path display, `$env:` facts) remains a UI design decision with snapshot surface, deferred with stage 1.

# Agent Note: Windows 默认改用 pwsh（路线图）
Status: proposed
[English](2026-08-01-windows-pwsh-default.md) | 中文
## 问题
harness 交付的执行配置在每个平台都是 bash 优先。Windows 主机必须安装 bash 垫片（WSL 或 Git-Bash），或退回到仅 POSIX 的 `dsh-bash-local` 行为；面向模型的 bash 工具教的是 bash 方言，TUI/Web 界面按照 bash 风格的预期渲染终端输出。第一块 Windows 原生基础已随 [pwsh 执行器与工具决策](../../implemented/feature/2026-08-01-pwsh-tool-and-executor.md) 交付：`ctx.bash` seam 的 PowerShell 实现与对等的 `pwsh` 工具——但还没有任何东西让 Windows 主机默认使用它们。
## 提案
两个阶段，各自可独立交付。bash 工具对等孪生已随 [pwsh 工具与 bash 对齐决策](../../implemented/feature/2026-08-02-pwsh-tool-bash-parity.md) 交付：`tool-pwsh` 现在除 sandbox 接口外，在前台与后台工作方面均与 `tool-bash` 对齐，通过 `dsh-bash-env` 共享 `DSH_*` 环境，并携带其组装后形态的 keyless 应用快照。
1. **Windows 默认组合**——交付的 CLI（命令行界面）组合在 Windows 主机上挂载 `dsh-pwsh-local` 作为 `ctx.bash` 执行器、`dsh-tool-pwsh` 作为面向模型的 shell 工具（那里不挂载 bash），POSIX 主机保持 bash 栈。这是 `base.cordis.yml` 与 surface 覆盖层里按平台门控的组合/清单决策；它让交付的 Windows 体验端到端 PowerShell 原生。
2. **pwsh GUI 渲染**——Web 界面使用 bash 风格的终端呈现来渲染 pwsh 调用（带胶囊状退出状态标签的终端卡片），与 bash 终端卡片相对应。已随 [pwsh UI 呈现与 bash 对齐决策](../../implemented/feature/2026-08-05-pwsh-ui-bash-parity.md) 及 keyless web 通道交付；TUI 已移除，不再有对应的终端界面。超出 bash 对齐的 PowerShell 感知呈现（原生路径显示、`$env:` 信息）仍无人认领。
各阶段仅在有依赖关系时排序：渲染阶段已随 [pwsh UI 呈现与 bash 对齐决策](../../implemented/feature/2026-08-05-pwsh-ui-bash-parity.md) 先行交付（平台无关，其 keyless web 通道可在任意宿主运行），而 Windows 默认组合仍是唯一未交付的阶段。本提案不改变任何 POSIX 行为。
## 备选方案
**在 `dsh-bash-local` 内部让 Windows 默认 pwsh（一个执行器，方言开关）。** 否决，理由与执行器决策否决模式开关相同：执行器的身份就是它 spawn 的 shell，而按平台门控的组合是部署选择，不是执行器配置。
**把 Windows 默认与执行器/工具一起交付。** 否决：清单变更需要自己的证据（交付的 Windows 树停挂 bash 后什么会坏、哪些工具依赖 bash 语义），并且它属于会在审批／PTY 界面上显现的组合决策。
**用垫片在 Windows 上保留 bash，跳过 PowerShell 默认。** 否决：这延续了安装税与路线图要消除的方言错配；垫片是部署要求，不是产品行为。
## 验收标准
- 运行交付版 `dsh` TUI/Web 的 Windows 主机无需配置即获得 `pwsh` 作为其 shell 工具、PowerShell 作为 `ctx.bash` 执行器，且那里的模型可见清单中没有 `bash`。
- POSIX 主机逐字节不受影响（清单相同，执行器相同）。
- 交付组合 e2e 在两个平台族上断言按平台门控的清单。
- 阶段 1 落地时，parity 变更带来的 keyless pwsh 工具快照已经就位；阶段 2 已随 web `pwsh-terminal` 渲染通道落地（TUI 的移除意味着不再有可供快照测试的终端界面）。
## 风险
- **依赖 bash 的组合行**——任何假设 bash 语义的交付插件（执行 shell 钩子的钩子桥接、工作区工具）必须按阶段审计；审计可能迫使分阶段推出而非一次切换。
- **Windows CI 覆盖缺口**——单元覆盖在 Linux 上运行；pwsh 栈里仅 Windows 的回归通过 Windows 构建/静态通道与 e2e 暴露出来；这些覆盖必须按阶段扩展，不能想当然地认为已经具备。
- **渲染约定**——与 bash 风格一致的终端呈现已随 web 通道交付；超出 bash 对齐的 PowerShell 感知呈现（原生路径显示、`$env:` 信息）仍是一项需要快照覆盖的 UI 设计决策，随阶段 1 一起延期。

# @deepseek-ai/dsh-pwsh-sandbox
English | [中文](README.zh.md)
Sandbox-consuming PowerShell implementation of the [`ctx.bash` executor seam](../bash/): every command runs as `pwsh -NoLogo -NoProfile -NonInteractive -Command <command>` **confined through `ctx.sandbox`**, with the selected mode, enforcement, and denial facts stamped on each settled result. The pwsh twin of [`@deepseek-ai/dsh-bash-sandbox`](../bash-sandbox/), a call-for-call mirror per the [pwsh executor and tool decision](../../../.agents/notes/implemented/feature/2026-08-01-pwsh-tool-and-executor.md) — the confinement substance is platform-neutral: on Windows the sandbox seam resolves to the ACL restricted-token runner chain ([`@deepseek-ai/dsh-sandbox-windows-acl`](../../sandbox/sandbox-windows-acl/)), on Linux/macOS to bwrap/Landlock/Seatbelt.
The executor inherits [`@deepseek-ai/dsh-pwsh-local`](../pwsh-local/)'s process mechanics and consumes its argv-level seam (`argv()` / `runArgv()` / `startArgv()` / `onProcessDone()`) to wrap the exact pwsh invocation through the provider. The sandbox policy (mode + workspace root) is NOT this package's config: it rides each call from `ctx.sandboxPolicy` (tool calls pass the calling session's resolved policy; direct calls fall back to deployment policy).
## Behavior
- `danger-full-access`: commands run through the local executor unchanged; results carry `sandbox: { mode, denied: false }`.
- Confined modes (`read-only`, `workspace-write`): the pwsh argv is wrapped by `ctx.sandbox.confine()`; runner-launch refusal fails closed with `SANDBOX_UNAVAILABLE` (foreground throw, background `runnerFailed` fact), and a denied write classifies against the selected backend's `denialSignatures` into `sandbox.denied`.
## Model Experience
### Confinement works, denial surfaces as command failure
#### What the model sees
The confined command's own stderr (e.g. `Access to the path '...' is denied.` under the Windows ACL runner); the tool layer converts classified denials into the standard permission-denied surface exactly as it does for the bash tool.
#### Token effect
No model-visible text beyond the command's stderr and the tool layer's standard denial surface.
#### KV Cache effect
None directly; the denial surface belongs to the tool layer.
## Known Limitations and Deferred Work
- **Reads are unrestricted** on Windows (the ACL runner restricts writes only); the read boundary is documented in `@deepseek-ai/dsh-sandbox-windows-acl`.
- **The Windows workspace-write temp area is the real temp directory** (`GetTempPathW`). This is a deliberate backend-defined choice, the same decision Landlock makes (`readWrite: ['/tmp', ...]`): the seam's "backend-defined temp area" permits it, and the escape probe in `tests/acl.e2e.ts` lives outside the temp tree for exactly that reason. A per-run private temp (bwrap's `--tmpfs /tmp` semantics) would additionally need an environment-block rewrite in the runner; it is an optional future hardening, not a correctness gap.
- **Windows read-only is strict zero-grant** — not even the NUL device is writable; `> $null` redirection still works (documented in the backend package).

# @deepseek-ai/dsh-pwsh-sandbox
[English](README.md) | 中文
沙盒消费型的 [`ctx.bash` 执行器 seam](../bash/) 的 PowerShell 实现：每条命令以 `pwsh -NoLogo -NoProfile -NonInteractive -Command <command>` 运行，**经 `ctx.sandbox` 隔离**，选定模式、强制完整性、拒绝事实都盖在每次结算的结果上。它是 [`@deepseek-ai/dsh-bash-sandbox`](../bash-sandbox/) 的 pwsh 孪生，按 [pwsh 执行器与工具决策](../../../.agents/notes/implemented/feature/2026-08-01-pwsh-tool-and-executor.md) 逐调用镜像——隔离实体本身是平台无关的：Windows 上沙盒 seam 解析到 ACL 受限令牌 runner 链（[`@deepseek-ai/dsh-sandbox-windows-acl`](../../sandbox/sandbox-windows-acl/)），Linux/macOS 上解析到 bwrap/Landlock/Seatbelt。
执行器继承 [`@deepseek-ai/dsh-pwsh-local`](../pwsh-local/) 的进程机制，并消费其 argv 级 seam（`argv()` / `runArgv()` / `startArgv()` / `onProcessDone()`）把精确的 pwsh 调用经 provider 包装。沙盒策略（模式 + 工作区根目录）不是本包的配置：每次调用由 `ctx.sandboxPolicy` 随行（工具层传调用会话解析后的策略；直接调用回退到部署策略）。
## 行为
- `danger-full-access`：命令经本地执行器原样运行；结果携带 `sandbox: { mode, denied: false }`。
- 受限模式（`read-only`、`workspace-write`）：pwsh argv 由 `ctx.sandbox.confine()` 包装；runner 启动失败按 fail-closed 抛 `SANDBOX_UNAVAILABLE`（前台抛错、后台记 `runnerFailed` 事实），被拒绝的写按所选后端的 `denialSignatures` 分类为 `sandbox.denied`。
## 模型体验
### 隔离生效，拒绝以命令失败呈现
#### 模型看到什么
受限命令自身的 stderr（Windows ACL runner 下如 `Access to the path '...' is denied.`）；工具层把分类后的拒绝转成标准权限拒绝面，与 bash 工具完全一致。
#### Token 影响
除命令 stderr 与工具层标准拒绝面外，无额外模型可见文本。
#### KV Cache 影响
无直接影响；拒绝呈现面属于工具层。
## 已知限制与后续工作
- **Windows 上读不受限**（ACL runner 只限写）；读边界文档在 `@deepseek-ai/dsh-sandbox-windows-acl`。
- **Windows workspace-write 的临时区域是真实临时目录**（`GetTempPathW`）。这是有意为之的后端自定义选择，与 Landlock 的决策（`readWrite: ['/tmp', ...]`）同类：seam 的 "backend-defined temp area" 词汇表允许它，`tests/acl.e2e.ts` 的逃逸探针也正是因此位于 temp 树之外。按运行创建私有临时目录（bwrap `--tmpfs /tmp` 的语义）还需 runner 改写环境块——这是可选的进一步加固，而非正确性缺口。
- **Windows read-only 是严格零授权**——连 NUL 设备都不可写；`> $null` 重定向不受影响（后端包有文档）。

Result text contains stdout, an optional `[stderr]` section, then applicable truncation, timeout, signal, and exit markers. A clean exit (0, no signal) produces no marker; an empty body renders as `(no output)`. Truncation links a safe complete spill file or reports it unavailable. Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Windows reports forced termination as exit 1 without a signal, so `[killed by signal: …]` is POSIX-only there. Only infrastructure failures — spawn errors and aborts (`tool call aborted`) — produce `isError`.

Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Windows reports forced termination as exit 1 without a signal, so `[killed by signal: …]` is POSIX-only there. Only infrastructure failures — spawn errors and aborts (`tool call aborted`) — produce `isError`.
The canonical success is `{ kind: 'foreground', ...BashRunResult }` for a completed foreground process or `{ kind: 'background', taskId }` for a published task. The renderer preserves exactly `started background task <id>` for background acks; programmatic consumers use the typed fields without parsing the rendered text. The canonical success is `{ kind: 'foreground', ...BashRunResult }` for a completed foreground process (with the executor's `sandbox` facts — `mode`/`denied`, optional `enforcement`/`runnerFailed` — projected when present) or `{ kind: 'background', taskId }` for a published task. The renderer preserves exactly `started background task <id>` for background acks; programmatic consumers use the typed fields without parsing the rendered text.
When `run_in_background` is true, this plugin preflights `ctx.tasks.start()` before spawning, registers the calling agent as owner, and adapts the returned `BashProcess` handle into generic cancel/done/incremental-output hooks. The task runtime owns ids, cross-session isolation, completion notices, waiting, and disposal cleanup; this plugin only maps pwsh exit facts into task output and outcome detail. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time.

## Known Limitations and Deferred Work ## Known Limitations and Deferred Work
- **No sandbox escalation** — `sandbox_permissions`/`justification` are absent; escalation waits for a Windows-confining executor (the bash tool's sandbox surface is not mirrored). - **ConstrainedLanguage and named-pipe capture under the Windows sandbox** — when the [Windows ACL sandbox](../../sandbox/sandbox-windows-acl/README.md) confines a call (read-only or workspace-write), the restricted token puts pwsh into ConstrainedLanguage mode: `Add-Type`, non-core .NET statics (`[System.IO.*]::`, `[math]::`), COM objects, and reflection fail with "only core types" errors, and the mode cannot be lifted from inside. The same modes deny named-pipe opens, so a piped-stdio spawn inside a confined command fails with EPERM. The tool description teaches both contracts to the model; the backend README owns the full limitations.
- **No persistent shell or PTY** — every call starts a fresh `pwsh -Command`; the PTY backends are Linux/macOS-only. - **No persistent shell or PTY** — every call starts a fresh `pwsh -Command`; the PTY backends are Linux/macOS-only today, and a Windows ConPTY persistent shell is roadmap work.
- **PowerShell-dialect contract** — the model must write PowerShell (native paths, `$env:` variables), not bash; there is no dialect translation. - **PowerShell-dialect contract** — the model must write PowerShell (native paths, `$env:` variables), not bash; there is no dialect translation.
- **Session-cwd identity is not canonicalized** — the workdir base is the session header cwd as-is, unlike the bash tool's sandbox-root-canonicalized identity; only the sandbox-less case applies here. - **Session-cwd identity is not canonicalized** — the workdir base is the session header cwd as-is, unlike the bash tool's sandbox-root-canonicalized identity. Under a confining executor the policy's workspace root IS canonicalized (by the shared policy service), so the workdir and the confinement root can diverge when the raw session cwd differs from its canonical form — a parity gap deferred to the shared shell-tool base extraction.

Windows hosts booting a shipped profile additionally receive [`windows.cordis.patch.yml`](windows.cordis.patch.yml): it disables the POSIX-only bash stack (`bash-sandbox`/`tool-bash`) and inserts the sandbox-confined PowerShell stack (`@deepseek-ai/dsh-pwsh-sandbox`, `@deepseek-ai/dsh-tool-pwsh`). The permission surface stays exactly as on POSIX: `sandbox`/`sandbox-policy` enforce the file-effect policy through the Windows ACL restricted-token runner (the win32 chain of `dsh-sandbox-local` → `@deepseek-ai/dsh-sandbox-windows-acl`), the permission switcher and the approval service run unchanged, and `fs-sandbox` keeps fencing `ctx.fs` writes — mounting `dsh-fs-local` alongside it would double-register `ctx.fs` and fail the load. The launcher applies the layer between the bundle layers and the user layers on win32 hosts; a Windows host that prefers the unconfined local pwsh executor or full access overrides these rows through its profile or home `cordis.patch.yml` (the bash-restore recipe must be complete: disable `pwsh-sandbox`/`tool-pwsh` AND re-enable `bash-sandbox`/`tool-bash` — both executor families register the same `bash` service, so an incomplete recipe fails loud at load).

# @deepseek-ai/dsh-sandbox-windows-acl
English | [中文](README.zh.md)
Windows write-restriction sandbox backend for the [harness sandbox seam](../sandbox/): a Node.js/[koffi](https://koffi.dev/) port of the mechanism in [huoyaoyuan/windows-acl-restrict-poc](https://github.com/huoyaoyuan/windows-acl-restrict-poc) (`10e4dfb`, the fixed revision), mounted as the win32 rung of the [`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/) chain (`workspace-write` / `read-only` modes); the same package carries the Linux/macOS backends.
Mechanism in one line: the caller's token is duplicated into a `WRITE_RESTRICTED` token whose restricting SIDs include a write SID (`S-1-4-x-y`) whose Write ACEs exist only on the workspace and the session's private temp directory. The write SID is the per-WORKSPACE identity, derived deterministically from the canonical workspace path (`workspaceWriteSid`), so the workspace-root ACE materializes once per workspace per machine — every later session, call, or restart hits the exact-ACE skip — instead of once per session (see [The confinement runner](#the-confinement-runner)). Windows then grants a write only where BOTH the caller's normal access AND the restricting-SID intersection allow it — the write SID is the write allowlist, and it grants nothing anywhere else on the system; the token's write check also inherits the ambient write ACEs of the OTHER restricting SIDs (the keep-alive group logon SID + Everyone — the Modes section below is the complete boundary).
Building directly on the raw ACL mechanism is the recorded design choice: it implements both confinement modes without the problems the rejected container options carry — see the [design note](../../../.agents/notes/implemented/feature/2026-08-08-windows-acl-restricted-token-sandbox.md) ([mxc](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md) needs an OS floor of Windows 11 24H2 and wholesale host DACL writes for arbitrary-path reads; AppContainer cannot do arbitrary-path reads at all).
## Usage
```ts
import { AclSandbox, workspaceWriteSid } from '@deepseek-ai/dsh-sandbox-windows-acl'
const workspaceRoot = process.cwd()
// mode selects the token's restricting-SID list (see Modes below) and must
// match the grant shape: read-only pairs with zero grants. workspace-write
// REQUIRES the workspace's write SID — the per-workspace identity.
const sandbox = new AclSandbox({ writableDirs: [workspaceRoot], writeSid: workspaceWriteSid(workspaceRoot), mode: 'workspace-write' })
await sandbox.init() // throws on ANY Win32 failure — never spawns unrestricted
const child = sandbox.spawn({ command: 'pwsh', args: ['-NoProfile', '-Command', '...'], cwd: workspaceRoot })
const { stdout, stderr, exitCode } = await child.wait()
sandbox.dispose() // revokes the revocable (temp) grant, keeps the standing workspace ACE; reports every cleanup failure
```
A direct `AclSandbox` grants the workspace ACEs STANDING (dispose() leaves them — they are the cross-instance reuse cache) and the temp ACE revocably (dispose() revokes it, so an inheritable ACE never outlives the instance on the ambient temp root). The server-side reuse is the `AclWriteGrant` class: `add(path, standing)` per directory, `dispose()` revokes the revocable paths and frees the SID — see the runner contract below. Every Win32 API call in this package is checked; failures throw `Win32Error` carrying the API name, the exact Win32 code, the `FormatMessageW` system text, and the failing path/context. This is deliberate: the POC ignored every return value and, when `CreateRestrictedToken` failed, silently ran the child with the FULL unrestricted token (fail-open). This port fails closed by construction.
## The confinement runner
The seam-facing shape is the **runner entry** (`./runner`), the argv-prefix wrapper `@deepseek-ai/dsh-sandbox-local` spawns in place of the caller's command — the same architecture as bwrap/landlock-run/sandbox-exec, so the sandbox seam's `confine()` contract needs no change. Stable argv contract:
```sh
node runner.js --workspace <dir> --temp <dir> --mode <read-only|workspace-write> [--write-sid <S-1-4-…>] -- <argv...>
```
The runner creates the restricted token, spawns the wrapped argv under it with the caller's stdio passed straight through (the caller's pipes, made inheritable around the spawn — Node clears stdio inheritability at startup, which raw spawns must compensate for), wraps the child in a `KILL_ON_JOB_CLOSE` job (a dead runner kills the child), ignores its own console Ctrl+C so the child handles its own, mirrors the child's exit code, and revokes its temp grant on exit (workspace ACEs stand). Every runner-side failure prints `windows-acl-run: <detail>` to stderr and exits 127 — the seam's `RUNNER_FAILURE_RULES` match that signature, so a runner refusal is never mistaken for a denial.
**Workspace grant reuse** (`--write-sid`): the write SID is DERIVED from the workspace path — no SID or temp-dir state is stored anywhere (the previous per-session random SID and its tamper surface are gone). The seam materializes the workspace ACE STANDING (once per workspace per server lifetime, never revoked — it is the reuse cache) and the temp ACE revocably (revoked on provider dispose), both lazily at the session's first confined execution. The session's private temp subdirectory is DERIVED from the session id + workspace (sha256, 16 hex) instead of stored: a resumed session derives the same directory and re-grants it (the exact-ACE skip keeps that O(1)), while a fork's different session id derives a fresh one. The directory is created EXCLUSIVELY — a pre-existing entry or a reparse point fails the first confined run loudly, so the grant never lands on a foreign object — and removed again on provider dispose. Under `--write-sid` the runner neither grants nor revokes (`manageDacls: false`) — the flag's presence marks the seam-managed contract, its value is the derived SID; without it (standalone use) the runner self-manages with the SAME derived SID (workspace ACEs standing, temp ACE revocable per call). Re-granting after a restart is idempotent: `grantWrite` reads the current DACL and SKIPS the `SetNamedSecurityInfoW` apply when the exact ACE already stands (that apply eagerly re-propagates the identical ACE across the whole tree — minutes on large workspaces). Standing ACEs from an unclean shutdown need no garbage collection — they ARE the cache; the same derived SID re-hits them forever. Known cost: materializing the grant on a big workspace tree blocks for the full eager propagation once per workspace per machine (the first confined write ever on this host).
Modes (the token's restricting-SID list follows the mode; the keep-alive group is logon SID + Everyone in BOTH modes — early DLL init dies with `0xC0000142` and CNG crashes pwsh with `0xE0434352` without them):
- `workspace-write` (logon SID, Everyone, write SID): the workspace and the session's PRIVATE temp subdirectory carry the write-SID Write grant; every other write is denied by the token intersection.
- `read-only` (logon SID, Everyone — NO write SID): STRICT zero grants — nothing is writable. The write SID stays OUT of the list on purpose: the standing workspace grant ACE from an earlier workspace-write period (a `/permission` downgrade, or a crash-resumed session) remains INERT under read-only because the write-restricted pass-2 check grants only what the restricting list carries — while the standing ACE keeps the re-upgrade free of re-propagation. NUL writes are AMBIENT, not granted: the device DACL grants Everyone read+write+execute (`0x1201BF`), so openers whose mask fits it (cmd `> NUL`, node `\\.\NUL`) can write it in BOTH modes — the sandbox cannot zero-grant the NUL device while Everyone stays in the keep-alive group. `Set-Content NUL` fails in both modes (a PowerShell/.NET-layer effect, pinned by the read-only suite — the device DACL is not the denying party); PowerShell's `> $null` redirection keeps working (it discards without opening NUL).
Authenticated Users is absent from BOTH lists — the WMI namespace security check fails (`0x80041003`), so CIM cmdlets and `Get-ComputerInfo` (which silently returns incomplete results rather than an error) are unavailable in EVERY confined mode, and the C:\-root tree-creation escape (standing `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACEs) is closed in both — the model-facing surface documents that contract, not a prompt promise. INTERACTIVE/LOCAL are absent from BOTH lists too: the host's Public tree grants write to INTERACTIVE, so Public writes are denied — pinned by the runner's ambient-writable Public-probe regression (see the design note).
The `AclSandbox` class (`tempDir: null` disables the temp grant) remains the programmatic API for direct spawns; `AclWriteGrant` is the server-side materialization half of the grant lifecycle.
## Header verification
All constants, signatures, and struct layouts were verified against the Windows headers on the development machine (MinGW `winnt.h` / `accctrl.h` / `aclapi.h` / `securitybaseapi.h` / `sddl.h` / `processthreadsapi.h` / `fileapi.h` / `namedpipeapi.h` / `synchapi.h` / `winbase.h`) and are cross-checked at runtime by [`verify/abi-probe.cpp`](verify/abi-probe.cpp) (sizes, offsets, enum values, static asserts):
```sh
g++ -std=c++20 -municode -O2 -o abi-probe.exe verify/abi-probe.cpp -ladvapi32 && ./abi-probe.exe
```
The koffi struct definitions assert their sizes against the probe at module load, so a header/koffi layout drift fails loudly instead of corrupting memory.
## Verified boundaries (inherent to restricted tokens, not this port)
- **Writes are restricted; reads, network, and process visibility are not.** `WRITE_RESTRICTED` intersects write accesses only, so a confined child can read any caller-readable file and open sockets. `read-only` mode therefore cannot be expressed by this mechanism alone; pair it with a read-side policy or an AppContainer/`S-1-15-2` capability token for stronger confinement.
- **Console isolation is unavailable.** Under the restricted token, children created with `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` die during DLL initialization with `STATUS_DLL_INIT_FAILED` (`0xC0000142`). The POC tried to fix this by adding the console logon SID (`S-1-2-1`) to the restricting list; on Windows 11 26200 `CreateWellKnownSid(WinLocalLogonSid)` fails with `ERROR_INVALID_PARAMETER` (87), the correct `WinConsoleLogonSid` yields a valid `S-1-2-1` but the child still dies, and the POC's final revision removed both the SID and console isolation. Children therefore share the host console; stdio redirection is pipe-based and unaffected.
- **ACL grants are standing directory mutations.** They persist if the process dies mid-run; workspace ACEs are standing BY DESIGN (never revoked — the reuse cache), temp ACEs are revoked by `dispose()` (`init()` also revokes an already-applied temp grant when a later step fails). The POC's documented manual cleanup (`icacls <dir> /remove '*S-1-4-…'`) fails on this platform with `ERROR_NONE_MAPPED` (1332) — revoke through this module instead. An unclean shutdown needs no self-healing for the workspace ACE: the derived SID re-hits the standing ACE on the next provision (skipping the apply); the write-SID ACE never accumulates a second identity per restart because the identity IS the workspace.
- **Granted directories must be caller-owned.** The owner's implicit `WRITE_DAC` is what lets the sandbox edit the DACL without elevation.
- **The temp grant follows `GetTempPathW`** — pass `tempDir` explicitly whenever possible. `GetTempPathW` reads the NATIVE environment block, which host runtimes that manage `process.env` through worker pools may not keep in sync (verified with vitest: a worker-side `process.env.TMP` change never reached the native block). The seam passes the session's PRIVATE subdirectory (`<temp>\dsh-<16 hex>` derived from the session id + workspace, created exclusively — a pre-existing entry or reparse point fails loudly); a defaulted grant landing on the real temp dir inherits `(OI)(CI)` over every subdirectory of temp, silently widening the allowlist — point it at a per-sandbox directory instead.
- **The confined child's temp root is private per session** (workspace-write + `--write-sid`): the runner rewrites TMP/TEMP via `SetEnvironmentVariableW` to the session's private subdirectory before the spawn and the child inherits the rewritten block (bwrap `--tmpfs /tmp` semantics). Read-only leaves the ambient temp entries untouched — writes there are denied anyway. The subdirectory is removed on provider dispose; after a crash it may survive as plain `%TEMP%` litter until OS temp hygiene (or manual removal) reclaims it — a later resume then fails loudly at the exclusive creation.
- **`whoami` and token-inspection cmdlets fail under the restricted token.** `GetTokenInformation` on the duplicate is partially unavailable to the child, so `whoami /all` reports errors — diagnostic noise of the restriction scheme, not an operational failure; the denial surfaces that matter (file writes) are unaffected.
## Model Experience
Indirectly, through [`dsh-bash-sandbox`](../../bash/bash-sandbox/README.md), [`dsh-pwsh-sandbox`](../../bash/pwsh-sandbox/README.md), and their tools, which render this backend's enforcement and denial facts (the confined stderr the tool layer classifies through `denialSignatures`) while the [`dsh-sandbox`](../sandbox/README.md) seam owns the `SANDBOX_UNAVAILABLE` text and runner selection.
#### KV Cache effect
None directly; the denial surface belongs to the tool layer.
## Known Limitations and Deferred Work
- **One write allowlist per workspace** — the write SID is the unit of the allowlist and IS the workspace identity; reusing one sandbox instance across two workspaces widens both grants to both roots (the same SID would then name two roots). Create one instance per workspace root — the seam does exactly this, keyed by the workspace path.
- **Cleanup is best-effort by design** — `dispose()` attempts every temp revocation and aggregates failures into an `AggregateError`; a cleanup failure leaves a standing (but write-SID-only) temp ACE that this process's next `init()`/`dispose()` cycle or `icacls` (via the ACE, not the trustee name) can still remove.
- **Standing workspace ACEs are invisible residue.** Renaming a workspace derives a new SID; the old ACEs on the old path stay (inert, write-SID-only). A future cleanup command may reap them; nothing re-propagates because of them.
- **NULL-DACL directories are not identity-preserving under grant+revoke.** A directory with a NULL DACL (rare — Windows-created directories carry real DACLs) means "everyone full control"; `grantWrite` builds the new ACL from that null, and the revoke round-trip leaves an EMPTY (deny-all) DACL rather than the original NULL DACL. The POC shares the behavior; real workspace and temp directories carry real DACLs, so this stays a documented edge rather than a guarded path.
- **Piped stdio capture is impossible for confined grandchildren (the named-pipe default SD template).** libuv's pipe stdio uses NAMED pipes; `CreateNamedPipeW` without security attributes installs the Win32 layer's user-mode default SD template (built by KernelBase — owner/SYSTEM/Admins full, Everyone/ANONYMOUS read-only, the fixed template [MS documents](https://learn.microsoft.com/en-us/windows/win32/ipc/named-pipe-security-and-access-rights)) — NOT the token default DACL, which is what the kernel applies to a raw SD-null create — so the client-end open requests write access no restricting SID is granted: `spawn(..., { stdio: 'pipe' })` inside a confined process fails with EPERM, the POC-documented "no output redirection" boundary of WRITE_RESTRICTED tokens. Inherited (`inherit`/fd) and ignored (`ignore`) stdio spawns work, and anonymous pipes (CreatePipe — a token-default-DACL consumer, e.g. PowerShell pipelines) work because the restricted token's default DACL carries a full-access restricting-SID ACE (set at init). A confined process therefore cannot capture a grandchild's output through a pipe; tools that must capture output cannot run confined.
- **Grant materialization is an eager full-tree propagation.** `SetNamedSecurityInfoW` on a directory with inheritable ACEs walks every descendant immediately (NOT lazily per access — measured at tens of seconds on large workspace trees plus the real temp root). The per-workspace identity pays it once per workspace per machine (lazily at the first confined execution ever, skipped entirely on every later provision when the exact ACE stands). If a workspace is huge, the first confined write on this host is correspondingly slow.
- **Resuming one session concurrently in two server processes fails the second at its first confined write.** Both processes derive the same private temp directory; the second one's exclusive creation hits the first one's directory and fails loudly. Single-writer session usage (the normal deployment) never sees this.
- **Read-side confinement and network policy are out of scope** — `WRITE_RESTRICTED` intersects write accesses only; pair this backend with a read-side policy for stronger confinement.
- **Wide-directory and FAT-volume warnings are deferred; FAT-class targets stay writable.** The UI-side warnings for granting unusually wide directories or FAT-class (non-ACL) volumes are not yet implemented, and a FAT volume as a grant ROOT simply fails the grant loudly (no ACL support). A FAT-class target OUTSIDE the granted roots is different: it has no security descriptors, so the restricted token's write check passes (Everyone sits in both lists) and such targets are writable under BOTH confined modes. FAT is treated as a legacy residue — unsupported and not engineered around; this warn-only posture is documented here rather than mitigated.
- **Both confined modes run `pwsh` in ConstrainedLanguage.** The restricted token trips PowerShell's lockdown detection, so under `read-only` AND `workspace-write` the language mode is ConstrainedLanguage: `Add-Type` (C# compile, P/Invoke), non-core .NET static calls (`[System.IO.*]::`, `[math]::`, `[Environment]::`), COM objects, and reflection fail with `Cannot create type` / `Cannot invoke method` ("only core types") errors, and `$ExecutionContext.SessionState.LanguageMode = 'FullLanguage'` is refused. Core cmdlets, core types (`[string]`, `[datetime]`, `[regex]`, `[guid]`), `-f` formatting, and property access keep working. The `pwsh` tool description teaches this contract to the model; `danger-full-access` calls run unconfined at FullLanguage.

# @deepseek-ai/dsh-sandbox-windows-acl
[English](README.md) | 中文
面向 [harness 沙盒 seam](../sandbox/) 的 Windows 写入限制沙盒后端：一个 Node.js/[koffi](https://koffi.dev/) 实现的、对 [huoyaoyuan/windows-acl-restrict-poc](https://github.com/huoyaoyuan/windows-acl-restrict-poc)（`10e4dfb`，修复后的修订）机制的移植，挂载为 [`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/) 链的 win32 一级（`workspace-write` / `read-only` 两种模式）；Linux/macOS 后端在同一包中。
一句话机制：把调用者令牌复制为 `WRITE_RESTRICTED` 受限令牌，其 restricting SIDs 中加入一个写入 SID（`S-1-4-x-y`），该 SID 的 Write ACE 只存在于工作区与会话的私有临时目录上。写入 SID 是**按工作区**的身份，由规范工作区路径确定性派生（`workspaceWriteSid`），因此工作区根目录 ACE 每台机器每个工作区只物化一次——之后每次会话、调用、重启都命中精确 ACE 跳过——而不是每会话一次（见[隔离 runner](#the-confinement-runner)）。此后 Windows 只在「调用者正常权限」与「restricting SID 交集」同时允许时才放行写入——写入 SID 就是写入白名单，而它在系统其余位置不授予任何权限；令牌的写检查还会继承**其他** restricting SID 的环境写 ACE（保活组登录 SID + Everyone——下文「模式」段是完整边界）。
直接构建在原生 ACL 机制上是记录在案的设计选择：它实现两种隔离模式，且不背负被否决的容器方案的问题——见[设计笔记](../../../.agents/notes/implemented/feature/2026-08-08-windows-acl-restricted-token-sandbox.md)（[mxc](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md) 要求 Windows 11 24H2 的 OS 下限，且任意路径读取需要整体改写宿主 DACL；AppContainer 根本无法任意路径读取）。
## 用法
```ts
import { AclSandbox, workspaceWriteSid } from '@deepseek-ai/dsh-sandbox-windows-acl'
const workspaceRoot = process.cwd()
// mode selects the token's restricting-SID list (see Modes below) and must
// match the grant shape: read-only pairs with zero grants. workspace-write
// REQUIRES the workspace's write SID — the per-workspace identity.
const sandbox = new AclSandbox({ writableDirs: [workspaceRoot], writeSid: workspaceWriteSid(workspaceRoot), mode: 'workspace-write' })
await sandbox.init() // throws on ANY Win32 failure — never spawns unrestricted
const child = sandbox.spawn({ command: 'pwsh', args: ['-NoProfile', '-Command', '...'], cwd: workspaceRoot })
const { stdout, stderr, exitCode } = await child.wait()
sandbox.dispose() // revokes the revocable (temp) grant, keeps the standing workspace ACE; reports every cleanup failure
```
直接使用 `AclSandbox` 时，工作区 ACE 以**常驻**方式授予（`dispose()` 保留它们——它们是跨实例的复用缓存），临时 ACE 以**可回收**方式授予（`dispose()` 撤销它，这样可继承 ACE 不会在环境临时根目录上比实例活得更久）。服务端复用则是 `AclWriteGrant` 类：每个目录一次 `add(path, standing)`，`dispose()` 撤销可回收路径并释放 SID——见下方 runner 契约。本包中的每个 Win32 API 调用都有检查；失败抛出 `Win32Error`，携带 API 名、精确 Win32 错误码、`FormatMessageW` 系统文本和失败的路径/上下文。这是刻意的：POC 忽略每个返回值，当 `CreateRestrictedToken` 失败时用完整无限制令牌静默运行子进程（fail-open）。本移植从构造上 fail-closed。
<a id="the-confinement-runner"></a>
## 隔离 runner
面向 seam 的形态是 **runner 入口**（`./runner`）：`@deepseek-ai/dsh-sandbox-local` 在调用者命令的位置 spawn 的 argv 前缀包装——与 bwrap/landlock-run/sandbox-exec 同一架构，因此沙盒 seam 的 `confine()` 契约无需改动。稳定的 argv 契约：
```sh
node runner.js --workspace <dir> --temp <dir> --mode <read-only|workspace-write> [--write-sid <S-1-4-…>] -- <argv...>
```
runner 创建受限令牌，在它之下 spawn 包装后的 argv，调用者的 stdio 直接透传（调用者的管道在 spawn 前后被设为可继承——Node 在启动时清除 stdio 可继承性，裸 spawn 必须补偿这一点），把子进程包进 `KILL_ON_JOB_CLOSE` job（runner 死亡则子进程死亡），忽略自身的控制台 Ctrl+C 让子进程自行处理，镜像子进程的退出码，并在退出时撤销其临时授权（工作区 ACE 常驻）。每个 runner 侧失败都会向 stderr 打印 `windows-acl-run: <detail>` 并以 127 退出——seam 的 `RUNNER_FAILURE_RULES` 匹配该签名，因此 runner 拒绝永远不会被误判为拒绝授权。
**按工作区授权复用**（`--write-sid`）：写入 SID 从工作区路径**派生**——任何地方都不存储 SID 或临时目录状态（先前每会话随机 SID 及其篡改面已移除）。seam 把工作区 ACE **常驻**物化（每个工作区每服务器生命周期一次，绝不撤销——它就是复用缓存），把临时 ACE **可回收**物化（提供方 dispose 时撤销），两者都在会话首次受限执行时惰性进行。会话的私有临时子目录由会话 id + 工作区**派生**（sha256、16 位 hex）而非存储：恢复的会话派生同一个目录并重新授权（精确 ACE 跳过使这一步保持 O(1)），而 fork 的不同会话 id 会派生出一个全新的目录。该目录以**独占**方式创建——已存在条目或重解析点会让首次受限运行大声失败，因此授权永远不会落到外部对象上——并在提供方 dispose 时再次移除。传入 `--write-sid` 时 runner 既不授权也不回收（`manageDacls: false`）——该标志的存在标记 seam 管理的契约，其值即派生 SID；不传它（独立使用）时 runner 用**同一个**派生 SID 自行管理（工作区 ACE 常驻，临时 ACE 每次调用可回收）。重启后重新授权是幂等的：`grantWrite` 读取当前 DACL，当完全相同的 ACE 已存在时跳过 `SetNamedSecurityInfoW` 的应用（该应用会把相同的 ACE 急切地重新传播到整棵树——大型工作区上以分钟计）。异常关闭遗留的 ACE 无需垃圾回收——它们**就是**缓存；同一个派生 SID 永远重新命中它们。已知代价：在大型工作区树上物化授权会阻塞整次急切传播，每台机器每个工作区一次（该主机上的第一次受限写入）。
模式（令牌的 restricting-SID 列表随模式而变；保活组登录 SID + Everyone 在**两种**模式下都存在——没有它们早期 DLL 初始化会以 `0xC0000142` 死亡、CNG 会让 pwsh 以 `0xE0434352` 崩溃）：
- `workspace-write`（登录 SID、Everyone、写入 SID）：工作区与会话的**私有**临时子目录携带写入 SID 的 Write 授权；其余写全部被令牌交集拒绝。
- `read-only`（登录 SID、Everyone——**不含**写入 SID）：**严格零授权**——没有任何可写位置。写入 SID 有意留在列表**之外**：先前 workspace-write 时期留下的常驻授权 ACE（`/permission` 降级，或崩溃后恢复的会话）在 read-only 下保持**失效**，因为 write-restricted 的 pass-2 检查只授予 restricting 列表所携带的内容——而常驻 ACE 让重新升级免于重新传播。NUL 写入是**环境性**的、不是被授权的：设备 DACL 授予 Everyone 读+写+执行（`0x1201BF`），因此访问掩码落在其内的打开者（cmd 的 `> NUL`、node 的 `\\.\NUL`）在**两种**模式下都能写——只要 Everyone 还在保活组里，沙盒就无法把 NUL 设备归零。`Set-Content NUL` 在两种模式下都失败（PowerShell/.NET 层效应，由 read-only 套件钉住——拒绝方不是设备 DACL）；PowerShell 的 `> $null` 重定向不受影响（它直接丢弃、不打开 NUL）。
Authenticated Users 在**两种**列表中都不存在——WMI 命名空间安全检查失败（`0x80041003`），因此 CIM cmdlet 与 `Get-ComputerInfo`（它静默返回不完整结果而非报错）在**所有**受限模式下都不可用，且 C:\-root 树创建逃逸（常驻的 `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACE）在两种模式下都被关闭——面向模型的表面记录的是该契约，而不是提示词承诺。INTERACTIVE/LOCAL 在两种列表中同样不存在：宿主的 Public 树向 INTERACTIVE 授予写权限，因此 Public 写入被拒绝——由 runner 的环境可写 Public 探针回归测试钉住（见设计笔记）。
`AclSandbox` 类（`tempDir: null` 禁用临时授权）仍是直接 spawn 的编程 API；`AclWriteGrant` 是授权生命周期的服务端物化一半。
## 头部验证
所有常量、签名与结构体布局都在开发机上对照 Windows 头文件（MinGW `winnt.h` / `accctrl.h` / `aclapi.h` / `securitybaseapi.h` / `sddl.h` / `processthreadsapi.h` / `fileapi.h` / `namedpipeapi.h` / `synchapi.h` / `winbase.h`）验证过，并在运行时由 [`verify/abi-probe.cpp`](verify/abi-probe.cpp)（大小、偏移、枚举值、静态断言）交叉检查：
```sh
g++ -std=c++20 -municode -O2 -o abi-probe.exe verify/abi-probe.cpp -ladvapi32 && ./abi-probe.exe
```
koffi 结构体定义在模块加载时对照探针断言其大小，因此头文件/koffi 布局漂移会大声失败而不是破坏内存。
## 已验证边界（受限令牌固有，非本移植引入）
- **写入受限；读取、网络与进程可见性不受限。** `WRITE_RESTRICTED` 只交叉检查写访问，因此受限子进程可以读取调用者可读的任何文件并打开套接字。`read-only` 模式因而不能仅靠该机制表达；将其与读侧策略或 AppContainer/`S-1-15-2` capability 令牌配对以获得更强隔离。
- **控制台隔离不可用。** 在受限令牌下，以 `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` 创建的子进程在 DLL 初始化期间以 `STATUS_DLL_INIT_FAILED`（`0xC0000142`）死亡。POC 尝试把控制台登录 SID（`S-1-2-1`）加入 restricting 列表来修复；在 Windows 11 26200 上 `CreateWellKnownSid(WinLocalLogonSid)` 以 `ERROR_INVALID_PARAMETER`（87）失败，正确的 `WinConsoleLogonSid` 能产出合法 `S-1-2-1` 但子进程仍然死亡，POC 的最终修订同时移除了该 SID 与控制台隔离。子进程因此共享宿主控制台；stdio 重定向走管道，不受影响。
- **ACL 授权是对真实目录的驻留改动。** 进程中途死亡会留下授权；工作区 ACE **按设计**常驻（绝不撤销——复用缓存），临时 ACE 由 `dispose()` 撤销（后续步骤失败时 `init()` 也会撤销已应用的临时授权）。POC 注释里的手工清理命令（`icacls <dir> /remove '*S-1-4-…'`）在本平台实测失败（`ERROR_NONE_MAPPED` 1332）——请通过本模块回收。工作区 ACE 在异常关闭后无需自愈：派生 SID 在下一次供给时重新命中常驻 ACE（跳过应用）；写入 SID ACE 不会因每次重启而累积第二个身份，因为身份**就是**工作区。
- **被授权目录必须由调用者拥有。** 所有者的隐式 `WRITE_DAC` 是沙盒无需提权即可编辑 DACL 的原因。
- **临时授权跟随 `GetTempPathW`**——尽可能显式传 `tempDir`。`GetTempPathW` 读取**原生**环境块，而通过 worker 池管理 `process.env` 的宿主运行时可能没有与之保持同步（vitest 实测：worker 侧的 `process.env.TMP` 变更从未到达原生块）。seam 传入会话的**私有**子目录（`<temp>\dsh-<16 hex>`，由会话 id + 工作区派生、独占创建——已存在条目或重解析点会大声失败）；默认授权落在真实临时目录上会让 `(OI)(CI)` 继承到临时目录的每个子目录，静默扩大白名单——请改指向每个沙盒的目录。
- **受限子进程的临时根目录按会话私有**（workspace-write + `--write-sid`）：runner 在 spawn 之前用 `SetEnvironmentVariableW` 把 TMP/TEMP 改写为会话的私有子目录，子进程继承改写后的环境块（bwrap `--tmpfs /tmp` 的语义）。read-only 保持环境中的临时目录条目不动——那里的写入反正会被拒绝。子目录在提供方 dispose 时移除；崩溃后它可能作为普通 `%TEMP%` 垃圾存活，直到 OS 的临时目录卫生（或手动删除）将其回收——之后的恢复会在独占创建处大声失败。
- **受限令牌下 `whoami` 与令牌检查 cmdlet 会失败。** 子进程对复制令牌的 `GetTokenInformation` 部分不可用，因此 `whoami /all` 报错——这是限制方案的诊断噪音，不是运行故障；真正重要的拒绝面（文件写入）不受影响。
## Model Experience
间接地通过 [`dsh-bash-sandbox`](../../bash/bash-sandbox/README.md)、[`dsh-pwsh-sandbox`](../../bash/pwsh-sandbox/README.md) 及其工具呈现：它们渲染此后端的强制与拒绝事实（工具层通过 `denialSignatures` 分类的受限 stderr），而 [`dsh-sandbox`](../sandbox/README.md) seam 拥有 `SANDBOX_UNAVAILABLE` 文本与 runner 选择。
#### KV Cache 影响
无直接影响；拒绝面属于工具层。
## Known Limitations and Deferred Work
- **每个工作区一个写入白名单** —— 写入 SID 是白名单的基本单位，且**就是**工作区身份；同一沙盒实例跨两个工作区复用时，两个根目录会互相扩大授权面（同一个 SID 将命名两个根）。请按工作区根目录各建一个实例——seam 正是这样做的，以工作区路径为键。
- **清理尽力而为** —— `dispose()` 会尝试全部临时撤销并把失败聚合为 `AggregateError`；清理失败只会留下仅含写入 SID 的临时 ACE，本进程下次 `init()`/`dispose()` 循环或 `icacls`（按 ACE 而非受托者名）仍可清除。
- **常驻工作区 ACE 是不可见残留。** 工作区改名会派生新的 SID；旧路径上的旧 ACE 留在原地（失效、仅含写入 SID）。未来的清理命令可以回收它们；它们不会引起任何重新传播。
- **NULL-DACL 目录在 grant+revoke 往返下不保持身份。** 带 NULL DACL 的目录（罕见——Windows 创建的目录都带真实 DACL）意味着「所有人完全控制」；`grantWrite` 从该 null 构建新 ACL，撤销往返后留下的是 EMPTY（全部拒绝）DACL 而非原始 NULL DACL。POC 行为相同；真实工作区与临时目录都带真实 DACL，因此这仍是记录在案的边界情形而非守护路径。
- **受限孙进程的管道 stdio 捕获不可用（named pipe 的默认 SD 模板）。** libuv 的管道 stdio 用的是 NAMED pipe；不带安全属性调用 `CreateNamedPipeW` 时，其默认安全描述符不是内核的模板，而是 Win32 层在用户态安装的默认 SD 模板（由 KernelBase 构建——owner/SYSTEM/Admins 全权，Everyone/ANONYMOUS 只读，即 [MS 文档](https://learn.microsoft.com/en-us/windows/win32/ipc/named-pipe-security-and-access-rights)记载的固定模板）——**不是**令牌默认 DACL（后者才是内核在原始 SD-null 创建时应用的）——因此 client 端打开所请求的写访问没有任何 restricting SID 被授予：受限进程内 `spawn(..., { stdio: 'pipe' })` 以 EPERM 失败，这是 POC 记载的 WRITE_RESTRICTED「无法重定向输出」边界。继承（`inherit`/fd）与忽略（`ignore`）stdio 的 spawn 可用；匿名管道（CreatePipe——令牌默认 DACL 的消费者，例如 PowerShell 的管道）因受限令牌默认 DACL 携带 restricting SID 全权 ACE（init 时写入）而可用。受限进程因此无法用管道捕获孙进程输出；必须捕获输出的工具无法在受限下运行。
- **授权物化是急切的全树传播。** 在带可继承 ACE 的目录上调用 `SetNamedSecurityInfoW` 会立即遍历每个后代（**不是**按访问惰性进行——大型工作区树上实测数十秒，加上真实临时根目录）。按工作区身份每台机器每个工作区只付一次（在首次受限执行时惰性进行，之后每次供给在精确 ACE 常驻时完全跳过）。如果工作区巨大，该主机上的第一次受限写入相应变慢。
- **两个服务器进程并发恢复同一会话时，第二个会在其首次受限写入处失败。** 两个进程派生同一个私有临时目录；第二个的独占创建撞上第一个的目录并大声失败。单写者会话用法（常规部署）永远不会遇到。
- **读侧隔离与网络策略不在范围内** —— `WRITE_RESTRICTED` 只交叉检查写访问；将此后端与读侧策略配对以获得更强隔离。
- **宽目录与 FAT 卷警告已推迟；FAT 类目标保持可写。** 对异常宽的目录或 FAT 类（非 ACL）卷的 UI 侧警告尚未实现，且 FAT 卷作为授权**根**只会大声失败（无 ACL 支持）。授权根**之外**的 FAT 类目标则不同：它没有安全描述符，因此受限令牌的写检查通过（Everyone 在两种列表中都在）——此类目标在**两种**受限模式下都可写。FAT 被视为遗留残留——不受支持、不围绕它设计；此处记录的是这种仅警告的立场，而非缓解措施。
- **两种受限模式都运行 ConstrainedLanguage 的 `pwsh`。** 受限令牌会触发 PowerShell 的锁定检测，因此在 `read-only` **和** `workspace-write` 下语言模式都是 ConstrainedLanguage：`Add-Type`（C# 编译、P/Invoke）、非核心 .NET 静态调用（`[System.IO.*]::`、`[math]::`、`[Environment]::`）、COM 对象与反射以 `Cannot create type` / `Cannot invoke method`（「only core types」）错误失败，且 `$ExecutionContext.SessionState.LanguageMode = 'FullLanguage'` 被拒绝。核心 cmdlet、核心类型（`[string]`、`[datetime]`、`[regex]`、`[guid]`）、`-f` 格式化与属性访问保持可用。`pwsh` 工具描述向模型传授该契约；`danger-full-access` 调用不受限地在 FullLanguage 下运行。

/**
* Windows ACL write-restriction sandbox backend for the DeepSeek Harness
* sandbox seam. Mirrors the mechanism of github.com/huoyaoyuan/
* windows-acl-restrict-poc @ 10e4dfb (the fixed revision): a WRITE_RESTRICTED
* token whose restricting SIDs include a write SID (`S-1-4-x-y`) that only
* this sandbox adds to the target directories' DACLs — the intersection
* check then allows writes exactly where that SID has a Write ACE, and
* nowhere else the write SID is concerned (the token's write check ALSO
* inherits the ambient write ACEs of the other restricting SIDs — the
* keep-alive group logon SID + Everyone; Authenticated Users, INTERACTIVE,
* and LOCAL are absent from both lists — see the seam's dual-list contract
* in `packages/sandbox/sandbox-local` and the package README's Modes section
* for the complete boundary). The write SID is the per-WORKSPACE identity
* ({@link workspaceWriteSid}): deterministic from the canonical workspace
* path, so the workspace-root ACE materializes once per workspace per
* machine and every later provision hits the exact-ACE skip — the
* grant-reuse story the per-session random SID paid a full tree propagation
* per session for. Unlike the POC, every API failure throws with the API
* name and exact Win32 code; a child is NEVER spawned unrestricted.
*
* Known boundaries (inherent to restricted tokens, not this port):
* - writes are restricted; reads, network, and process visibility are NOT
* (WRITE_RESTRICTED intersects only write accesses);
* - console isolation is unavailable — children share the host console
* (CREATE_NO_WINDOW / CREATE_NEW_CONSOLE children die with
* STATUS_DLL_INIT_FAILED under the restriction);
* - the temp directory and every writable directory must be owned by the
* caller (owner-implicit WRITE_DAC);
* - grants are standing ACE mutations on real directories. WORKSPACE grants
* are deliberately never revoked — the ACE is the cross-session reuse
* cache (revoking would force the next session to re-propagate the whole
* tree). TEMP grants are revocable: dispose() removes them so a standing
* inheritable ACE never outlives its session's temp directory (an
* inheritable ACE on the ambient temp root would otherwise widen the
* SID's write reach to every future temp file). With `manageDacls: false`
* the CALLER owns the DACLs (the sandbox seam's grant reuse):
* init()/dispose() skip grant/revoke entirely and the caller must not
* revoke under live children.

/**
* The windows-acl confinement runner: the argv-prefix wrapper the sandbox
* seam spawns in place of the caller's command. It creates the
* WRITE_RESTRICTED token with the workspace write-SID allowlist, spawns the
* wrapped argv under it with the CALLER'S stdio inherited (bytes flow
* straight through), mirrors the child's exit code, and revokes its temp
* grant on exit (workspace ACEs stay standing as the reuse cache).
*
* Stable argv contract (the seam builds it; a native-exe replacement would
* keep the same contract):
* [node, runner.js, '--workspace', <dir>, '--temp', <dir>,
* '--mode', <read-only|workspace-write>,
* ['--write-sid', <S-1-4-…>], '--', <argv...>]
*
* Modes:
* - workspace-write: the workspace and temp directories carry the orphan-SID
* Write grant; every other write is denied by the token intersection.
* - read-only: STRICT zero grants — no directory is writable, not even the
* NUL device (`> $null` fails with access denied); the restricting list
* carries no orphan SID, so a standing grant ACE from an earlier
* workspace-write period stays inert. BOTH modes drop Authenticated Users
* (CIM unavailable — documented in README) and INTERACTIVE/LOCAL (the
* Public tree writes are denied); the two lists share the keep-alive group
* (logon SID, EVERYONE) and differ only by the orphan.
*
* `--write-sid`: the seam's grant contract — the CALLER has already
* materialized the write-SID ACEs (the seam's workspace + private-temp
* grants, server lifetime) and owns their revocation, so the runner neither
* grants nor revokes (manageDacls: false). The carried SID is the
* per-workspace identity ({@link workspaceWriteSid}) — the seam derives it
* from the policy root; the flag's PRESENCE is the seam-managed marker (its
* value must equal the workspace-derived SID). Absent `--write-sid`
* (standalone/test use) the runner self-manages grants per invocation with
* the same workspace-derived SID (its workspace ACEs are standing — the
* reuse cache — and its temp ACE is revoked on exit). With `--write-sid` in
* workspace-write mode, the runner rewrites the TMP/TEMP entries of its OWN
* environment (SetEnvironmentVariableW) to the `--temp` directory — a
* PRIVATE per-session temp subdirectory the seam provisions (bwrap `--tmpfs
* /tmp` semantics) — and the child inherits the rewritten block (lpEnvironment
* NULL; an explicit block through koffi trips ERROR_INVALID_PARAMETER in
* CreateProcessAsUserW, verified empirically). Read-only leaves the ambient
* temp entries untouched (writes there are denied anyway).
*
* Failure contract: every runner-side failure (bad args, missing
* directories, token/grant/spawn errors) prints `windows-acl-run: <detail>`
* to stderr and exits 127 — the seam's RUNNER_FAILURE_RULES matches that
* signature. The child is NEVER spawned unrestricted.

* canonicalization converges case/alias spellings, so two spellings of one
* workspace derive one SID; an as-spelled fallback path would mint a second
* identity for the same directory (self-healing, at the cost of one extra
