    # Duban: 3 damage (local ally of itself — challenger)
    duban_after = next(d for d in new_state.demons if d.unit_id == "001")

    murmur_after = next(d for d in new_state.demons if d.unit_id == "002")
    assert murmur_after.damage == 3, (
        f"Murmur should take 3 Fixed Damage when Truth is revealed (local ally). "
        f"Got {murmur_after.damage}."
    )

    # No CP change — Question removal is not a death
    assert new_state.players[Side.PLAYER_1].cp == 0, "P1 should gain 0 CP (Question not dead)."
    assert new_state.players[Side.PLAYER_2].cp == 0, "P2 should gain 0 CP."
