An internal Addok API client was implemented with controlled errors and mocked response tests. The interface was clear enough to integrate, but no live Addok/BAN instance was provisioned or exercised.
- What worked
- The HTTP response model was simple to represent and test, and self-hosting met the privacy and external-dependency constraints.
- What got in the way
- Real service reliability, indexing, and operational setup remain unassessed because the geocoder and its data were not available.
