AI First Legacy Migration
summary
An agentic orchestration pipeline extracts language‑agnostic specs using CodeGraph, LLM agents, Ader and Glean, then deterministically regenerates apps with a specification engine and stateful test-driven generation. The system runs automated validation, mutation testing (80% baseline), Dependabot/TruffleHog security checks and an iterative self‑correction loop. Applied to Ruby→Kotlin and PHP→TypeScript migrations it achieves one‑to‑one parity against ~2,000 legacy test cases while cutting human hours ~4× and total cost ~5×.
