To bypass rigid security headers and CSRF requirements, the engine uses a dual-layer strategy interacting across both Isolated and Main script worlds. It features a robust session interception system that discovers and inherits valid tokens dynamically. It includes a sophisticated 403 error auto-cooldown bridge and direct DOM configuration injection.
