Architectural Amnesia: Solving the Context Gap in AI-Assisted Legacy Modernisation
Most legacy modernisation programs fail not because of bad tools, but because AI is thrown at code with no context: thousands of files, zero documentation, tribal knowledge lost, incident history scattered across ticketing systems. To make AI coding assistants reliable in these environments, you have to build technical knowledge layers that encode not just what the code does, but why it exists and how it behaves in production. This article goes deep into how to structure repositories, documentation, runbooks, and incident logs so that AI assistants can reason about legacy systems in cross‑industry IT / DevOps landscapes (banking, manufacturing, telecom, government) instead of just autocompleting syntax.
