The problem. Blockchains have largely treated identity, authorization, and control as one object—the private key. That compression is under strain: post-quantum signatures are large; institutions need conditional, revocable control; AI agents need bounded autonomy; wallet recovery still depends on a single master backup; cross-chain identity fragments; and everyone pays the cost of “every node does the same verification.” The separation. ACE-GF splits identity binding from per-transaction autho
