⚯ LAZARUS — Autonomous Legacy Modernization Engine Lazarus is a self-healing legacy software archaeology and migration engine built for the agentic era. Powered by Gemini 3.5 Flash and Google Managed Agents, it ingests ancient mainframe COBOL, automatically extracts undocumented business rules, translates the code to Python 3.12, and proves correctness byte-for-byte against a live GnuCOBOL differential oracle. Instead of generic syntax translation, Lazarus runs a secure 8-stage pipeline inside a hosted Google Linux sandbox. When a translation fails due to mainframe dialect quirks, the agent enters an iterative self-healing loop: it diagnoses the failure, authors a custom Markdown skill, commits it to the repository, and dynamically heals its own code on the next turn.
