Problem

The Linux capture-helper staging test fails on Windows because it expects POSIX executable mode 0755, while Windows reports 0666.

Change

Only assert POSIX permission bits on non-Windows hosts. Windows still verifies staged helper contents, and the Hyprland protocol files remain checked. No production behavior changes.

Scope and approval

This is a small, focused fix for an obvious platform-specific test defect, qualifying for the exception without a prior issue or discussion.

Verification

On Windows x64:

• Before: the helper staging test failed with expected 0755, received 0666.
• After: vp test run lib/cli-external-packages.test.ts build-desktop-artifact.test.ts passed all 98 tests in 7.61s. Removed inherited ELECTRON_RUN_AS_NODE only from the test shell to avoid the separate existing environment-sensitive native-probe assertion.
• vp lint scripts/build-desktop-artifact.test.ts passed.
• vp run --filter @t3tools/scripts typecheck passed.
• git diff --check passed.

Linux/macOS execution was not available locally; their permission assertion is preserved.

Model: gpt-6.1-sol. Harness: Codex in T3 Code.

Approvability

Verdict: Approved at ef41d8c

Macroscope's review found this PR approvable — This is a narrowly scoped, test-only Windows compatibility adjustment in an ignored path; it preserves the substantive staging checks and does not alter product behavior, defaults, or static-analysis policy.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

📝 Walkthrough

The Linux capture-helper staging test now checks executable permission bits only on non-Windows hosts. Windows still runs the staging test without the POSIX mode assertion.

Changes: Capture-helper staging test

Layer / File(s)	Summary
Platform-specific permission assertion scripts/build-desktop-artifact.test.ts	The test reads the host platform and checks mode 0o755 only when the platform is not win32.
