    +"""Tests: kanban worker spawn pins TERMINAL_CWD to the task workspace.
    +
    +Regression coverage for #34619 and #41312 (same root cause): ``_default_spawn``
    +launched the worker subprocess with ``cwd=workspace`` and set
    +``HERMES_KANBAN_WORKSPACE``, but did NOT set ``TERMINAL_CWD``. Because
    +``TERMINAL_CWD`` takes precedence over the process cwd in both
    +``tools/file_tools.py::_resolve_base_dir`` (relative ``write_file`` paths) and
    +``agent_init``'s context-file loader (``AGENTS.md`` discovery), workers inherited
    +the dispatching gateway's cwd — relative writes landed in the gateway user's
    +home (#41312) and the wrong profile's ``AGENTS.md`` was loaded (#34619).
    +Pinning ``TERMINAL_CWD`` to the workspace fixes both.
