Scenario fixtures record each step; a failing step fails only the tests
that assert on it. running() and raise_interrupt() live in helpers.py.
put_file probes parent directories with a HEAD request instead of a
get_archive stream. stream_run uses restore_latest and asserts its result.
Docstrings no longer refer to the removed Bash suite.
