# input_auto.ludic — proves the frame loop commits the device layer automatically
# (#83): a real handler game reads Input.active in its Update phase and NEVER calls
# Input.poll by hand, yet the action fires from the live key. Before this fix the
# loop only fed Input.key(), so Input.active read empty unless the game polled.
#
# Driven headless by the keys on stdin — one char per frame. With "llq": frame 1
# and 2 read 'l' (the action key), frame 3 reads 'q' (which quits). So the action
# is active on exactly two frames.
#
# Run:  printf 'llq' | bin/ludic examples/library/input_auto.ludic   ->  2
