- Fix wrong comments on graph launch tracker entries: they claimed correlation works "via CUPTI_ACTIVITY_KIND_GRAPH_TRACE", but that approach was rejected (GRAPH_TRACE suppresses per-kernel records). The actual mechanism is the shared correlationId across all nodes in one graph launch. - Fix ConcurrentHashMap::fetch() missing its read lock — a pre-existing data race now exercised by the new graph correlation hot path. - Cache PersistentState::Get().cudaGraphCurrentLaunch in a local ref inside matchGraphActivityToAPICall instead of calling Get() twice.

Tracy Profiler
A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
Tracy supports profiling CPU (Direct support is provided for C, C++, Lua, Python and Fortran integration. At the same time, third-party bindings to many other languages exist on the internet, such as Rust, Zig, C#, OCaml, Odin, etc.), GPU (All major graphic APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
