Knowledge as Code: A Pattern for Knowledge Bases That Verify Themselves

Documentation rots. You know this. You've seen internal wikis with pages last updated in 2023 that everyone still treats as authoritative. You've inherited a knowledge base where half the links are dead and nobody knows which facts have drifted. The usual response is to assign someone to "maintain the docs." This works until that person gets busy, changes roles, or leaves. Then the decay resumes, silently, until the wrong person relies on the wrong fact.
