MOAD-0003 (Leaked Context): CLEAN

Blender has several thread_local uses (gpu_context.cc active_ctx,
gpu_immediate.cc imm, draw_context.cc DRWContext::g_context). These are
per-thread GPU rendering contexts, which is the correct use of thread-local
storage for thread-affine GPU resources. They do not hold request-scoped
identity (e.g., user session, render job ID) that should be passed explicitly.
No Leaked Context defect found.
