-## The Universal Asset Forge
-`coreason-meta-engineering` acts as the deterministic mathematical toolchain (EDA) for expanding the CoReason ecosystem. It is an active engineering service rather than a passive library—it strictly parses Python as a Concrete Syntax Tree (`libcst`), rigidly enforces cryptographic URN discovery bounds, and strictly avoids probabilistic AI logic execution when generating code.
