Includes 27 harness subsystems—hint engine with 30+ rules, outcome classification, pattern learning, and DOM compression achieving 15x token efficiency—that guide AI agents and prevent costly error cascades. Achieves ~300MB memory for 20 parallel sessions versus 5GB+ for traditional approaches, while remaining invisible to bot detection and enabling authenticated cross-site operations.
