# Tier 4 — lifecycle / teardown safety net.
#
# Everything above renders in steady state and kills waybar with SIGTERM, which
# never runs the C++ destructors. The crash classes that hurt most (exit,
# DPMS/output unmap, reload) all live in that create/destroy path, so exercise it
# explicitly under ASan:
#   1. clean exit on SIGINT (the real Bar teardown path, #5182)
#   2. runtime output hotplug (bar + module destruction while running, #5182)
#   3. visibility toggle + config reload churn (SIGUSR1 / SIGUSR2)
#   4. fast-interval modules torn down mid-tick (thread vs destructor races)
#
# Usage: lifecycle.sh
