 * strict job lints every C file under cbits on Linux; the Haskell side
 * picks the platform's answer at compile time and never calls the stub. */

 * Returns 1 on success, 0 when refused or unsupported - a non-NTFS
 * volume, policy, a non-empty directory, or a non-Windows build - and

 * path is a live branch, never an assert. */
