Game: Neon Inferno Demo; executable: NEON INFERNO.exe. Thread: 1564820458161963139. Latest report 1565703417446408292 and earlier 1564823584952688714 end with whole-app SIGNALED status=9 on NVIDIA SHIELD/Tegra, with no Wine termination, tombstone or perf capture, across DXVK 1.9.2 and 1.14.1. Last graphics line is Emulating vkResetQueryPool on a private queue (family=0 index=1). Source inspection shows this is printed AFTER native vkCreateDevice, command-pool/buffer and fence creation succeed; it is not evidence of a failed native create. Existing WRAPPER_DIAG reports capabilities only at the end of device setup, may redirect stdout/stderr, and its attachment has repeatedly not arrived. Existing info/error messages do not bracket the remaining startup operations; WSI MESA_TRACE_FUNC is not the recovered normal log. This is diagnostic round 1, not a claimed SIGKILL fix. Add normal-stderr monotonic/pid/device markers scoped to this executable and NVIDIA vendor, bracketing device initialization, host-query-reset submission/wait, first four legacy queue submissions, swapchain creation, acquire and present. Preserve all Vulkan arguments, results, waits, queue selection and graphics policy; preserve member Proton 11 ARM64EC and DXVK selection. Verify GN-WRAPPER-STARTUP-v1 in the next recovered normal report, identify the last entered operation without a return, or establish graphics progressed before the app died. The sender of SIGKILL remains unknown and app RSS alone does not rule out system-wide memory pressure. Local diff --check passes; Android compilation/package verification via CI.
