Two problems made a missing Wayland compositor look like broken tests. The cleanup traps ended on a bare conditional, so when a test skipped before creating its TMPDIR the trap's last command returned 1 and, under set -e, that overrode the explicit exit 0. Six tests that launch quickshell had no compositor guard at all, so they ran anyway and failed on the Qt platform plugin. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
