"""S5.3 CLI-parity tests for ``run.main()`` single-project flags (Steps 2/4/5).

In-process ``run.main([argv])`` + rc + ``capsys`` substring asserts (never subprocess),
mirroring ``tests/test_live_dry_run.py``. Every arm is offline — it stops before the first
model call (``debate.run``), so no socket/network is exercised (brief NFR). The bundle
fixture ``shared/examples/bygg-energi-mikro`` (project ``BYGG-KONTOR-NORD``) supplies citable
content so the dry-run reaches its offline return.
