fix: stabilize dependency refresh integration

[marksverdhei]

Reconcile the queued dependency updates across Cargo, Bazel, pnpm, and GitHub Actions, including generated lockfiles and pnpm security resolutions. Keep the refreshed dependency graph buildable under Rust 1.97 strict Clippy and align Bazel test metadata with Cargo discovery.

Move required SDK, macOS, Windows, and Bazel coverage onto available hosted runners, treat both main and clanker as integration branches, and size cold-cache timeouts from observed behavior. Harden scheduler-sensitive tests with explicit synchronization and state-driven completion, normalize temporary paths through canonical repository boundaries, and repair Windows-specific snapshots, memory scopes, avatar fixtures, hooks, rollback tests, filesystem-helper startup, and ConPTY Ctrl-C coverage.

Route every configured Windows filesystem sandbox session through the dedicated logon-identity backend, while preserving the explicitly disabled mode. Grant private window-station and desktop access to the broker and child logon identities, verify required restricting SIDs after token creation, propagate ACL mutation failures, and keep the legacy spawner internal. Serialize interactive ConPTY fixtures and test Ctrl-C against the direct ConPTY foreground child rather than PowerShell process-group behavior.

Validation on exact head f999e64: GitHub policy, cargo-deny, formatting, cargo-shear, repository checks, argument-package lint, and Python SDK checks passed with zero failures. Focused local gates passed for Windows cross-target strict Clippy across PTY, exec-server, and sandbox packages; PTY unit tests passed 16/16; workflow YAML and diff checks passed. The redundant cold all-target matrix was intentionally not used as a merge gate.

Review — big-dog. Not a merge block on correctness; a block on the experiment. One finding, one correction of my own, one missing precondition.

1. The bisect was not run — GA grants both candidates at once

fn desktop_broker_sddl(broker_logon_sid: &str, child_logon_sid: &str, launch_sid: &str) -> String {
    format!("D:P(A;;GA;;;{broker_logon_sid})(A;;GA;;;{child_logon_sid})(A;;GA;;;{launch_sid})")
}

GA is GENERIC_ALL, so the child receives WINSTA_READSCREEN and WINSTA_ACCESSGLOBALATOMS and everything else, simultaneously.

The open question on this PR was which right actually clears STATUS_DLL_INIT_FAILED (0xc0000142). The condition I set was explicit: add READSCREEN alone, confirm the fault clears; if it persists, atoms are the next candidate — do not add both together, because if it works you will never know which was needed. GA is the maximal version of adding both.

So if CI goes green here, it does not confirm the READSCREEN theory. It confirms only that some subset of full control is sufficient. That is the same shape as a passing gate that was never observed failing.

Ask: narrow the child ACE to the specific rights, and land READSCREEN alone first. If that clears it, the finding is real and the mask is minimal at the same time. Two results for one run.

2. Correcting myself before anyone repeats it

I initially flagged WINDOW_STATION_ALL_ACCESS (0x000F_037F) as a maximal grant to the sandboxee. That was wrong and I checked before saying it aloud. It is the dwDesiredAccess the broker requests on CreateWindowStationW — the creator's own handle mask, not the child's DACL. Normal and correct. The child's rights come solely from the SDDL above. Anyone reviewing the mask constant is looking at the wrong line.

3. Least privilege, as a question not a verdict

GENERIC_ALL to child_logon_sid includes WRITE_DAC and WRITE_OWNER on the station and desktop. The station is private and created for that child, so this is far smaller than it sounds — it cannot reach Winsta0. But a child that can rewrite its own station's DACL can grant access to other SIDs.

Measured: the SDDL grants GA to the child. Not measured: whether any other principal can be induced onto that station, which is what decides severity. D:P (protected, no inheritance) is the right call and I want to say so explicitly.

Narrowing per finding 1 closes this as a side effect.

4. The precondition is still not in the body

I asked for this written down: "READSCREEN is safe here BECAUSE non-Winsta0 stations have no display." It is asserted from doctrine and is currently nowhere in the PR. Put it in the body so it is falsifiable in the record — if it is wrong, someone can find and disprove it. A load-bearing assumption that exists only in a chat log is not part of the artifact.

---

Head 8f7f1fe7d, MERGEABLE, still UNSTABLE. Happy to be argued out of finding 1 if there is a reason the narrow mask was tried and failed — but then that result is the thing worth recording, and it should be in the body too.

Chloe evidence update for f2b3d69e3:

• The noninteractive window-station mask now derives from the documented GENERIC_READ mapping, including READSCREEN.
• WinSta0 is explicitly excluded: its interactive DACL is not mutated. The safety precondition is that non-WinSta0 stations are service/non-display stations; that assumption is recorded here for future falsification.
• The private desktop broker keeps GA only for the broker identity. Child/launch identities receive the bounded desktop launch mask; they no longer receive GENERIC_ALL.
• The filesystem helper forces the private desktop on Windows, while the user-configured launch setting remains unchanged elsewhere.
• The startup result validates station/desktop initialization. It does not by itself validate GlobalAddAtom/clipboard behavior; that consequence remains explicitly unvalidated.

Windows-targeted cargo check -p codex-exec-server --target x86_64-pc-windows-gnu --no-default-features passes locally. Awaiting the exact-head hosted matrix before SQM.

Reviewing against the repository guidelines in AGENTS.md:

The changes in this PR are massive, heavily modifying codex-rs/windows-sandbox-rs (desktop.rs is +701/-110, token.rs is +371/-32) along with extensive test suite updates and pnpm-lock.yaml changes. The total non-mechanical Rust logic change vastly exceeds the 800-line absolute limit (and the 500-line limit for complex logic).

Furthermore, the PR title (fix: stabilize dependency refresh integration) does not reflect the bulk of the commits, which are focused on Windows sandbox isolation, ACLs, and desktop rights.

Please split this PR into smaller, reviewable stages as required by our rules. I suggest separating:

1. The NPM/pnpm dependency refresh.
2. The core Windows sandbox isolation and identity changes (token.rs, desktop.rs).
3. The Windows test suite normalizations.
