Code costs trending to zero won't kill no-code. The cost of verifying, reproducing, and auditing outputs rises at the same time. The two stack as layers rather than competing as alternatives.
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.
The March 31, 2026 npm sourcemap incident revealed Claude Code internals. 4-phase execution, 7 modes, and the 11-step Agent Loop analyzed.

44 feature flags, 20 externally inactive. KAIROS, Auto-Dream, UltraPlan, Coordinator, Bridge, Daemon, UDS Inbox, Buddy, plus anti-distillation and undercover mode.
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.
52 built-in tools' common interface, 10-step execution pipeline, safe=parallel/unsafe=sequential concurrency model, 5-stage permission pipeline, and 888KB Tree-sitter 23-step bash security.
