Developer guide for migrating to reproducible environments without rewriting
The primary obstacle to adopting reproducible environments is often the assumption that environment parity requires containerizing legacy monoliths from scratch or abandoning stable CI/CD pipelines. In reality, reproducibility is about capturing application intent through configuration rather than rebuilding the application itself. This guide outlines a non-disruptive, incremental path to migrating your workflow to production-identical environments without touching your core codebase.
