These capabilities span the entire process of computing power supply, intelligent execution, and protocol access, and are used to establish: * Traceable data and state closure * Controllable model and strategy evolution path * Observable and controllable operating boundary * Isolation and security mechanisms for multi-protocol parallel operation Together, they determine whether AI and agents can operate as controllable financial execution units in the long term, and support the system in maintaining stability and predictability under conditions of high volatility and continuous iteration. --- # Agent Instructions This documentation is published with GitBook.
