ERC-3643: When Tokenization Becomes Architecture, Not Experiment

Early RWA tokenization failed because compliance lived off-chain and platforms became choke points.
ERC-3643 changes this by embedding identity and regulation directly into the token.

At the concept level, compliance becomes portable attached to the asset, not the venue.
At the execution level, every transfer enforces ONCHAINID checks and rule modules before value moves.

Identity is reusable, rules are modular, and recovery is native to the system.
Tokens remain ERC-20 compatible while enforcing legality in real time (T+0).

This is not a feature upgrade—it’s financial architecture maturing.
