"""WarRoomEngine coverage: EVENT-triggered campaign planning — armed,
X-creds gated, one-open-campaign dedup shared across BOTH entry points
(``run_cycle`` for the "run now" seam, ``open_for_release`` for the
release-publish hook), and the release-marker vs blank-brief distinction.

Mirrors test_x_engine.py's feature-spotlight-exploration block (same
_FakeClient/_NullClient injection pattern) and test_coroner_engine.py's
open_for_incident-style dual-path dedup coverage.
