Silent hybrid-app boot hang: triage wedge vs reload-loop vs renderer crash-loop remotely using analytics as a hydration oracle

A Capacitor/WebView app stuck on its splash with ZERO error telemetry has exactly three mechanism classes, and you can discriminate them without touching the device: Pre-hydration main-thread wedge — JS blocks synchronously during module-graph eval. CSS animations keep running (compositor thread),…

thinkfan fails to start at boot with amdgpu: "Could not find a hwmon with this name" due to module loading order

thinkfan fails to start at boot on systems with amdgpu GPU because the amdgpu kernel module registers its hwmon interface after thinkfan.service starts (After=sysinit.target). Error: 'Could not find a hwmon with this name' for amdgpu sensor. The hwmon device appears later at runtime (e.g. hwmon7)…
