fix(sandbox): harden the per-session record and the ACL runner failure paths (review round v6)
Durable record: bound to the owning session id and validated at the fold (orphan-SID shape, temp path inside the host temp root) — a fork's copied parent record no longer provisions the child, and a tampered record fails loud. Private temp dir: random unguessable name persisted in the record, created exclusively (pre-existing entries and reparse points fail EEXIST). Persistence: a fresh provision kicks an immediate flush (no write-behind debounce), narrowing the crash window to the flush latency — documented as the one self-healing gap. Runner-failure rules: exit-gated on 127 so a confined command that prints the signature on a non-127 exit is never misclassified. Spawn: AssignProcessToJobObject failure terminates the suspended child (no hanging orphans). SandboxExecutionPolicy.sessionId is the branded SessionId. Boundary docs: qualifying clause on the absolutist sentences, NULL-DACL Known Limitation, 'full' scoped to the supported NTFS surface, CLM gate comment.

## 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 an orphan SID (`S-1-4-x-y`); the orphan 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 orphan SID is PER SESSION, not per spawn: the seam provisions one SID per session as a log-only `sandbox/acl-session` event on the session log (fork mints a fresh one; resume replays the same one), materializes its ACEs lazily at the session's first confined execution, and holds them for the server process's lifetime (revoked on provider dispose; idempotent re-grant skips the eager full-tree re-propagation when the exact ACE survives a restart — no garbage collection). The token's restricting list is the keep-alive group plus the orphan SID only under workspace-write: read-only = [logon SID, Everyone] and workspace-write = [logon SID, Everyone, orphan]. 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 orphan: 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 unrevoked 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-<hash>`, TMP/TEMP rewritten by the runner — bwrap `--tmpfs /tmp` semantics). 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.

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 per-session grant machinery is pinned cross-platform by `packages/sandbox/sandbox-local/tests/acl-session.spec.ts` (record fold/provision, one-shot materialization, fork/resume SID reuse, dispose revocation, and the mode-switch cycle — read-only materializes nothing, the upgrade materializes once, the downgrade keeps the standing grant — with the Win32 surface mocked) and on win32 by `grant.spec.ts` (real-DACL materialization), the `acl.spec.ts` idempotent-grant fast-path, 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).

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 all grants on exit. 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.

**Per-session grant reuse** (`--write-sid`): the seam provisions ONE orphan SID per session — stored as a log-only `sandbox/acl-session` event on the session log, so a resumed session replays the SAME SID and a fork mints a fresh one — and materializes its ACEs lazily at the session's first confined execution, holding them for the SERVER process's lifetime (revoked on provider dispose). Under `--write-sid` the runner neither grants nor revokes (`manageDacls: false`); without it (standalone use) it self-manages per-call grants as before. 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: the session's record re-grants the same SID, and the next dispose revokes them. Known cost: materializing a grant on a big workspace tree blocks for the full eager propagation once per session per server lifetime.

**Per-session grant reuse** (`--write-sid`): the seam provisions ONE orphan SID per session — stored as a log-only `sandbox/acl-session` event on the session log (bound to the owning session id, validated at the fold), so a resumed session replays the SAME SID and a fork mints a fresh one — and materializes its ACEs lazily at the session's first confined execution, holding them for the SERVER process's lifetime (revoked on provider dispose). A fresh provision kicks an IMMEDIATE persistence flush right after the append (no write-behind debounce), so the record is durable within the flush latency — a crash inside that window can strand inert orphan-SID ACEs, the one documented self-healing gap (the spawn seams are synchronous, so no await barrier exists between record and ACEs). Under `--write-sid` the runner neither grants nor revokes (`manageDacls: false`); without it (standalone use) it self-manages per-call grants as before.

- **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; `dispose()` revokes them, and `init()` revokes already-applied grants 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. The per-session record makes an unclean shutdown self-healing: the same SID is re-granted on resume (skipping the apply when the ACE stands) and revoked at the next dispose; orphan ACEs never accumulate a new SID per restart.

The seam passes the session's PRIVATE subdirectory (`<temp>\dsh-<hash>`); 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 itself is plain `%TEMP%` litter with no garbage collection: OS temp hygiene reclaims it, and the record's determinism lets a later resume reuse it.
|
||||
- **`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.

- **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 (the seam's per-session record does exactly this: one SID per session, keyed to the session's immutable cwd).
|
||||
- **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.
|
||||
- **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.
|
||||
- **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-session reuse pays it once per session per server lifetime (lazily at the first confined execution, skipped entirely when the exact ACE survives a restart); the self-managed runner fallback still pays it per invocation. If a session's workspace is huge, the first pwsh call of each server lifetime is correspondingly slow.
|
||||
- **Resuming one session concurrently in two server processes grants two SIDs.** The durable record lives in the session log; both processes read or provision it independently, the per-path lock keeps the DACL merges consistent, and the last-written record wins for future resumes — the losing SID's ACEs are revoked by its own process's dispose. 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.
