#
#   tests/e2e.sh [path/to/dingger]

# The test daemon polls only every 30s, so every update asserted here must
# arrive through events (hook reports, focus pokes, tmux focus hooks), the
# same paths that make the real UI react immediately.

# Layout:
#   session a: window wa1 (pane A1, fake pi), window wa2 (pane A2, fake pi)
#   session b: window wb1 (pane B1, fake pi)
#   session viewer: a pane running a real tmux client attached to session b,
#                   so "what the user is looking at" is real tmux state.
