/**
 * Regression tests for #3509 — CLI breaks when repo path contains spaces
 *
 * Root cause: test code embedded space-containing paths into runGsdTools()
 * string args; the helper's whitespace tokenizer truncated paths at the first
 * space.  All calls that carry dynamic paths must use the array form of
 * runGsdTools() so execFileSync receives the full path as a single argv slot.
 *
 * These tests create a tmpdir whose prefix intentionally contains a space so
 * they remain red on a broken codebase regardless of the host machine's
 * tmpdir location.
