"""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.
