# F11 test driver — NOT part of the CI contract (CI only builds and runs the
# demo binary, whose built-in pass dumps the scroll-class device query and
# probes XSendEvent-fabricated wheel events, then exits 0). This driver adds
# real XTest wheel clicks (xdotool click 4/5/6/7) so both representations of
# a wheel event — core buttons and XI2 button events — are captured, and the
# XIPointerEmulated flag can be measured on the XI2 side. Run it from the
# repo dev shell (`nix develop`, for dub/xvfb-run); xdotool via `nix shell`.
#
#     ./run.sh        # build, then run both passes under Xvfb
#
# Passes (see ../../f11-scroll.md for the findings they produce):
#   A  built-in:  device query (scroll_class none=1 on every Xvfb device) +
#      XSendEvent probes (send_event=1, core-only, no XI2 twin)
#   B  driven:    WSI_DRIVEN=1 + xdotool wheel clicks against three phases —
#      dual_client (core on conn 2, XI2 on conn 1), dual_selection (one
#      client selecting core AND XI2: who gets the event?), then core_only
#      (XI2 selection cleared: does core delivery resume?)
