Executive Summary
This white paper shows how Google AI and CAST software mapping & intelligence combine to deliver deterministic, structure-aware understanding of large, custom applications – empowering LLM and making modernization decisions faster and safer.
Learn about:
- How to scale LLM-powered understanding to million-line estates for reliable impact analysis.
- An agentic approach that layers AI-generated documentation and vector search with CAST Imaging’s graph-based “digital twin” of the code to answer code-to-architecture questions with evidence.
- Concrete gains for teams – from accurate dependency and data-flow mapping to tighter test scoping, risk detection, and defensible rehost/replatform/refactor choices.
