Geocoding Error Lab: When Addresses, Maps, and Humans Disagree

An address field seems ordinary until delivery, events, or membership location depends on it. Participants debug geocoding failures: ambiguous place names, rural addresses, spelling variants, wrong countries, provider bias, and coordinates that cannot be trusted blindly.

The lab covers validation, human review, confidence scores, fallback flows, privacy limits, and how to store corrections. It is useful for event logistics, directories, services, and field operations.
