What building it taught us

The connector's own docstring, verbatim. It lives beside the code so it cannot drift from it.

World Bank WDI connector: annual consumer price inflation.

Kept alongside the IMF monthly data because it reaches back to 1960 for countries whose monthly history is short or missing entirely -- Australia's monthly CPI starts in 2025, but its annual series runs from 1960.

fetch() downloads with conditional requests and returns raw bytes; parse() turns a stored snapshot into observation rows. The driver decides what to store.
