Modernize legacy codebases (COBOL, legacy Java/C++/.NET, monolith web apps) with a structured preflight / assess / map / extract-rules / brief / (reimagine | transform | uplift) / harden / status workflow. Cross-stack rewrites, greenfield reimagining, and same-stack version uplifts (e.g. .NET Framework → .NET 8); an interactive topology viewer; specialist agents; and optional dynamic-workflow orchestration with adversarial verification.
