Phases A-C static diagnosis of the wl_proxy_add_listener null+8 crash.
Evidence-backed root cause, candidate patch verdict, ruled-out hypothesis
cross-check, and a copy-pasteable instrumented-rebuild runbook for the
orchestrator.
Verdict: candidate patch qtwaylandscanner-null-guard-listeners.patch guards
the CORRECT site (every generated init_listener). Necessary but not
sufficient alone — complementary to libwayland redox.patch hunk 1.
v5.5 'verified FIXED' claim overstated: never tested in isolation,
kded6 workaround masked it, stale-sysroot risk documented.
