/* Platform filesystem capabilities the store layer probes at runtime.
 * macOS-only functionality.  Every other platform compiles the constant
 * -1 stub because the cabal c-sources entry is unconditional and the
 * C99 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. */

 * implement the query, or a non-macOS build - and the caller falls back
