Architecture documentation that cannot drift

Drift is usually treated as a team failing. Someone forgot to update the diagram. Someone copied the schema into a slide and never updated it. The fix is always framed as more discipline, more process, more reviews. None of it works for long, because the condition is not behavioural. It is structural.

Most architecture toolchains look like this. The ER diagram lives in one tool. The API schema lives in another. The narrative document lives in a wiki. The slide deck lives in a shared drive. Each tool holds its own copy of the same entity. The moment you change one, the others are wrong, and nothing in the system forces them back into alignment.

This is the core reason NeoArc exists. Every other capability in the product follows from it. Model-first, single-source, derive everything that can be derived, and review the things that cannot. If you want to see how the pieces fit together, the product overview walks through the pipeline end to end.
