Legacy modernization is the process of re-binding decisions that earlier teams already bound - in older languages, against older requirements, often with the original intent now lost across generations of owners and maintainers. This model treats that work as a product rather than a one-off migration: the personas below carry distinct, frequently competing concerns, and the capabilities exist to serve those concerns explicitly rather than by informal consensus. The aim is to preserve business intent while replacing the runtime, surfacing trade-offs between stakeholders as deliberate choices instead of side effects of technical decisions.
