Given how far back these systems go, the real challenge isn’t just the code or the lack of documentation, but the tribal knowledge baked into them. A lot of the critical logic lives in conventions, naming patterns, and unwritten rules that only long-time SMEs understand.

Using AI and a few different modalities of information that exist about these systems (existing code, docs, AI-driven interviews, and workflow capture), we can triangulate and extract that tribal knowledge out.
