~/.cache/hermes-pytest failed seven files: a dot-dir ancestor made the hidden-dir search tests
see every fixture as hidden, and the longer root pushed the PulseAudio/voice AF_UNIX test
sockets past sun_path. /var/tmp is the FHS disk-backed temp root (never tmpfs), non-hidden,
and shorter than the old /tmp root. test_tool_result_storage asserts STORAGE_DIR instead of a
literal, and the zh-Hans bot-mode mirror follows the English code block it must copy.
