"""Live e2e smoke for the CLI **binary**, invoked as a child process via
``sys.executable -m notebooklm.notebooklm_cli`` (not a raw ``notebooklm`` binary —
CI PATH fragility). The notebook is passed by ``-n <id>`` / ``NOTEBOOKLM_NOTEBOOK``,
never ``notebooklm use`` (which mutates shared profile state).

These exercise the parts only a real subprocess can: argument parsing, the
console-script wiring, and the ``--json`` stdout/stderr split — including the
contract that on a LIVE failure ``--json`` still emits a single valid JSON object
on **stdout** (logs go to stderr).

Requires auth and the ``mcp`` extra (``importorskip`` — keeps this module skipping
in lock-step with the rest of the MCP/CLI-live suite when the extra is absent);
auto-marked ``e2e`` by ``conftest.pytest_itemcollected``.
