 - **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 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。

 - **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).

+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
 
-- **No `SandboxProvider` wiring yet** — this package is the primitives layer; the `ctx.sandbox.confine()` integration (spawn-side token application plus the `denialSignatures`/`runnerFailureRules` contract) is the next step and cannot reuse the argv-wrapping style of `dsh-sandbox-local` because the restricted token must be applied at `CreateProcess` time.
 - **One write allowlist per instance** — the orphan SID is the unit of the allowlist; reusing one sandbox instance across two workspaces widens both grants to both roots. Create one instance per workspace root.
 - **Cleanup is best-effort by design** — `dispose()` attempts every revocation and aggregates failures into an `AggregateError`; a cleanup failure leaves a standing (but orphan-SID-only) ACE that this process's next `init()`/`dispose()` cycle or `icacls` (via the ACE, not the trustee name) can still remove.
-- **Read-side confinement, network policy, and job-object kill-on-close are out of scope** for this layer and belong to the future provider design.
+- **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.
