Agentic Data Migration Engine

Agentic Data Migration Engine is a Codex-powered demo that turns a legacy user-domain schema into an inspectable migration specification and deterministic SQL. It orchestrates four agentic phases: schema inference from DuckDB fixtures, semantic enrichment grounded in profiling and target-model documentation, mapping generation with explicit transformation intent and approval state, and SQL compilation. Key features include a Kuzu graph-based digital twin, per-phase Markdown reports, JSONL audit logging, a machine-readable approval artifact, and compiled SQL models for dim_user, dim_role, bridge_user_role, and dim_address.
