Structured planning, parallel execution in git worktrees, and deep validation for Claude Code. Turns a one-line objective into a validated DAG of modules executed by worker agents, each self-checked and cross-module-reviewed before merge-back. 7 MCP tools: `validate`, `validate_plan`, `memory_recall`, `memory_save`, `iteration_state` (per-run scoped, with stagnation/velocity/oscillation detection)
