into editable Architectural Decision Records (ADRs) and recomposes them to modern stacks,
with an audit trail by default.
Key workflows:
- kaizen memsafe-roadmap: C/C++ to Rust migration with CISA-format memory-safety roadmaps
- kaizen migrate-plan: Framework modernization (AngularJS, .NET Framework, Java 8, etc.)
Requires ANTHROPIC_API_KEY or OPENAI_API_KEY environment variable.
