+"""Regression tests for profile-aware tilde expansion in file tools.
+
+The bug (#48552): in-process file tools (write_file, read_file, patch,
+search_files) resolved ``~`` via ``os.path.expanduser()``, which reads the
+gateway process's ``HOME``.  In profile mode (Docker, systemd, s6) the gateway
+``HOME`` differs from the profile ``HOME`` that interactive sessions use, so
+``~`` expanded to the wrong directory and file operations failed with
+"no such file or directory".
+
+The fix adds ``_expand_tilde()`` which delegates to
+``hermes_constants.get_subprocess_home()`` — the same policy the terminal tool
+uses for subprocess environments.
+
+See: https://github.com/NousResearch/hermes-agent/issues/48552
