# Manual two-process smoke test for lobby.tscn (task 1.5). BOTH roles load
# lobby.tscn as their actual current_scene via change_scene_to_file —
# matching how main_menu.gd's Host/Join flow (task 1.7) really gets a
# player there — rather than instantiating it as a child of this driver.
# That distinction matters: change_scene_to_file() operates on
# get_tree().current_scene, and calling it from a node that ISN'T an
# ancestor-chain match for current_scene (as an earlier draft of this test
# did, by add_child()-ing lobby.tscn under this driver) hung completely
# on disconnect — see multiplayer-todo.md §9 gotcha 27.
#
# The host role loading lobby.tscn is deliberate, not an oversight: a
# *dedicated* server (server_boot.tscn) never loads it, but a self-hosting
# player clicking main_menu.gd's Host button does — NetworkManager.host()
# then _leave_to_lobby(), landing them on lobby.gd's is_server branch (a
# read-only view of the roster, no team/ready controls). An earlier
# version of this test skipped that branch entirely on the mistaken
# assumption that "host" here meant "dedicated server"; adversarial review
# caught that it left a real, production-reachable code path untested.
#
# Not part of tests/test_runner.tscn — needs real ENet peers. Run:
#
#   godot --headless --path Game res://tests/lobby_smoke.tscn -- --role=host
#   godot --headless --path Game res://tests/lobby_smoke.tscn -- --role=client
