MOAD-0002 (Intertangle): CLEAN

Blender uses G.main (the global Main database) extensively, but this is
intentional architectural design: G.main is the single source of truth for
all scene data. It is not an "accidental" shared mutable god object coupling
independent subsystems. Each subsystem (depsgraph, render, physics) accesses
G.main through well-defined APIs (BKE_*). No Intertangle defect found.
