+"""Regression tests for the home-directory RuntimeError bug.
+
+Without the fix to ``agent/subdirectory_hints.py`` (add ``RuntimeError`` to
+the three ``except`` clauses around ``Path.expanduser()`` /
+``Path.home()``), the first two tests raise ``RuntimeError`` from inside
+the hint walker on POSIX systems.
+
+These tests use pytest's built-in ``tmp_path`` fixture and intentionally
+do not depend on the richer ``project`` fixture from
+``test_subdirectory_hints.py`` so the file is runnable standalone.
