 - **Onboarding friction for new knowledge bases.** If adding a new KB requires server-side configuration, custom endpoints, or domain-specific setup beyond pointing at a repo URL, the interface isn't consistent.
 - **Tools that work with one KB but break with another.** If an agent workflow built against the software canon fails when pointed at the theology KB, the interface promised consistency it didn't deliver.
