`buildWindowsRestrictAclArgs` invoked the hardening script as `powershell.exe -Command <script> <path> <sid> <isDir>`. `-Command` does not populate `$args`; it appends the trailing tokens to the command text. The script therefore read `$args[1]` as `$null`, threw `NullArrayIndex` at `$allowedSids[$sidText] = $true` under `$ErrorActionPreference = 'Stop'`, and exited 1. Both callers swallowed that: the async callback was empty and `applySecurePathRestriction` returned `true` regardless, while the sync `catch` returned `false` and nobody logged. Every Windows secure path has been left on its inherited ACL since the ACL was introduced (#5006), and nothing said so. Replace PowerShell with `icacls.exe`, which takes plain argv. That removes the quoting surface entirely rather than escaping it: interpolating a path into the command text would have turned a dead no-op into arbitrary PowerShell on a filesystem path, since `-Command` executes what it appends. It also drops the execution-policy dependency and the `powershell.exe` spawn an EDR flags, and runs ~25x faster than the PowerShell cold start. Hardening is now three passes: `/reset` to purge explicit ACEs that `/inheritance:r` leaves behind, `/inheritance:r` plus a `/grant:r` per allowed SID, then a read-back that checks the DACL is protected and grants only the intended rights. The predecessor's verification block was equally dead, and an apply that is never read back is only half a control. Failures stay non-fatal — non-NTFS volumes, network paths and restricted tokens fail legitimately and must not break startup — but they are no longer invisible: every failure is logged, and a failed async apply now evicts its cache entry so the next call retries instead of trusting a success that never happened. Routing through `runProcess`/`runProcessSync` also retires this file's `node:child_process` allowlist entry.
