The smoke test only exercised steady-state rendering and killed waybar with SIGTERM, so whole crash classes were invisible: exit-time use-after-free (#5182), module state transitions (#5183) and hardware-backed modules (#5179). Add tiers that hit those paths under ASan (+ _GLIBCXX_ASSERTIONS): - lib.sh: assert_clean_exit (SIGINT teardown -> checks segfault/abort + ASan report emitted during destruction), output hotplug helpers, signal/reload, WAYBAR_WRAP hook, opt-in leak detection. - lifecycle.sh (gating): clean exit, runtime output hotplug (Bar/module destroy), toggle/reload churn, fast-interval teardown race (#5182 class). - fuzz.sh (gating): pathological custom-backend output (empty, nonzero exit, invalid JSON, huge, non-UTF8, empty format). - coverage.sh (gating): every Factory module must be classified for smoke coverage; a new unlisted module fails the job (#5179 slipped through). - modules.sh: also render the whole matrix inside a group; SIGINT teardown per module instead of SIGTERM. - state.sh (best-effort): real mpd driven through an empty queue (#5183) + stop/clear; pulseaudio + slider on a null sink. - hardware.sh (best-effort): backlight, backlight/slider (#5179) and battery via umockdev. - leakcheck.sh (report-only): clean-exit run under LSan.

# Tier — custom-backend fuzz. The custom module's exec output flows straight into
|
|
# formatting / sanitising / (optionally) JSON parsing, so feed it the pathological
|
|
# inputs that tend to segfault (empty, non-zero exit, invalid JSON, huge, non-UTF8,
|
|
# empty format) and assert no crash / critical, including on clean exit.
