// TestWindowsSandboxHonorsShellQuotedCustomArg is the MUL-4957 round-3 must-fix
// 2 integration test. A `-c windows.sandbox=...` opt-in supplied shell-quoted
// (as users commonly type custom_args) reaches Codex normalized by
// agent.NormalizeCodexLaunchArgs; the Windows sandbox decision must consume the
// SAME normalized args, not the raw tokens, or the two drift and the user's
// isolation opt-in is silently downgraded. This locks the raw-args →
// normalized → policy chain end to end across the two packages so they cannot
// diverge again.
