tool-pwsh now renders sandbox denial facts (denial marker + same-turn escalation hint, runner-failed notice on background reads) and advertises the sandbox_permissions/justification escalation pair resolved through ctx.approval before execution — the shared fail-closed sequence from dsh-sandbox, with the tool name 'pwsh'. The description teaches the ConstrainedLanguage contract under the Windows sandbox (both confined modes run pwsh in CLM: Add-Type, non-core .NET statics, COM, and reflection fail; the mode cannot be lifted — probe-verified, pinned by LANGMODE assertions in the runner suite and description assertions in the tool suite). The stale pwsh-sandbox JSDoc ('the tool owns approval') and the parity notes' superseded 'minus sandbox' claims are corrected.
The duplication gate flags the call-for-call mirror of bash-sandbox's executor (the pwsh-tool-and-executor decision): wrap the class body in jscpd ignore markers, the same convention the invariant companions use.
Confine Windows command execution through a WRITE_RESTRICTED token whose restricting SIDs carry an orphan-SID write allowlist, ported from https://github.com/huoyaoyuan/windows-acl-restrict-poc (@ 10e4dfb). Every Win32 call is checked and fails closed - the POC silently ran children with the FULL token when CreateRestrictedToken failed.
- @deepseek-ai/dsh-sandbox-windows-acl: koffi primitives verified against the MinGW Windows headers (verify/abi-probe.cpp) plus the confinement runner ([node, runner, --workspace, --temp, --mode, --, argv...]: kill-on-close job, stdio passthrough, exit-code mirroring, windows-acl-run: failure signature, grant revocation). read-only = strict zero grants (NUL device not writable; documented). Windows-only execution: exempted from the Linux coverage lane (windowsOnlyCoverageExclusions).
- @deepseek-ai/dsh-sandbox-local: PLATFORM_CHAINS.win32 filled with the windows-acl runner (full enforcement, ACL denial dialect, runner-failure rules).
- @deepseek-ai/dsh-pwsh-sandbox: sandbox-consuming pwsh executor (call-for-call mirror of dsh-bash-sandbox) over a new argv-level seam in dsh-pwsh-local; per-file coverage complete via the fake-provider spec.
- bundle/base: the Windows platform layer mounts the confined pwsh roster - sandbox/policy/fs-sandbox/permission/approval re-enabled, the POSIX bash stack stays disabled.
