Geographic interoperability, from source geometry to executable platform geography

The geography a buyer requested, the geometry that was supplied, the canonical H3 representation, the circles or IDs a platform actually executed, and the geography used for reporting are usually five different objects. This knowledge base documents every conversion between them - with containment rules, approximation classes, units, tolerances, and the edge cases that break them.

The same treatment for time

A timestamp and its zone, the UTC instant it resolves to, the canonical hour-of-week slot, and the grain a platform executed - with DST gaps and folds, broadcast days, dayparts, and ISO weeks.
