# AE24-005

Tri-Layer Fallback Architecture achieves 99%+ uptime for browser automation: Layer 1 (Semantic Path via Crawl4AI, fast/cheap), Layer 2 (Vision Path via Gemini Flash, handles DOM obfuscation), Layer 3 (Fleet-Wide Immunity via parallel swarm, heals all agents before encountering errors). Generic platforms cannot do fleet-wide immunity.
