Profiler (Modules) collects per-frame wall and thread CPU time, named inclusive sections, counters and GPU durations. It is off by default, so a disabled scope costs one branch. Application, WidgetApplication, VulkanContext and Canvas mark the frame phases (process, dispatch, advance, draw, paint, UI flush, acquire, submit, present). GpuTimer wraps Vulkan timestamp queries in a small ring that is read without stalling; the window frame and any RenderBuffer that asks for it report GPU time into the profiler. InputRecording stores raw window input with exact timing, pen pressure and tilt as a line-based text file, and InputRecorder captures it through a new raw tap in the InputCoalescer that sees every platform event before coalescing.
