6-Layer agent system design canvas and 8+4 core patterns from the Claude Code source leak (512K lines TS). From the Circuit Breaker that stopped 250K/day wasted API calls with 3 lines, to 23-step bash AST security.
CC internal Memory System (4-type persistent memory, Auto-Dream, Auto-Compact) vs independently built 3-layer system (documents→index→semantic search). validate_placement() is the differentiator CC doesn't have.
