+**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 policy is `never`, 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` — composition config is the one override channel.
-- The permission switcher leaves the Windows roster; session permission facts pin the composition defaults through the approval service and sandbox policy.
 
 ## 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.
+- 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; `packages/bundle/base/tests/base.spec.ts` pins the shipped Windows roster (disables, inserts, and the `never` approval policy).
 - 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).

-# executor (its presets bundle a sandbox mode the unconfined pwsh executor
-# cannot honor), so the permission service and its client knob leave the
