The first run went green but the best-effort tiers silently didn't exercise
anything:
- state.sh: the mpd `audio_output { ... }` block was on one line, which mpd
rejects ("Unknown tokens after '{'"), so mpd never started and the mpd
sub-tier (the #5183 empty-queue repro) skipped. Split the block across lines.
Also move teardown into a cleanup() with `|| true` so a dead-pid kill under
`set -e` no longer makes the step exit 1.
- hardware.sh: umockdev-run's LD_PRELOAD lands ahead of the linked-in ASan
runtime, so ASan aborted before main() ("ASan runtime does not come first")
and waybar never started -- the backlight/slider (#5179) path wasn't tested.
Set verify_asan_link_order=0 so the instrumented binary runs under the preload.
- leakcheck.sh: abort_on_error=1 turned LSan's exit report into a core dump;
force abort_on_error=0 for this report-only tier.
- lib.sh: assert_clean now also flags "ASan runtime does not come first" so a
future preload/link-order regression fails loudly instead of passing.
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.
