What building it taught us

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

INEGI connector: Mexico's national CPI and 2024 basket weights.

INEGI's public CPI application uses an anonymous ASP.NET JSON service for its tree and posts selected series to a documented CSV export. The tree and CSV are archived as separate exact responses; parsing the CSV reads its sibling tree snapshot offline to recover source parentage. This is the same snapshot-sibling pattern used by the BLS connector for its catalogue.

The monthly table's main hierarchy is `por objeto del gasto`. Its SCIAN and durability cuts remain separate sections. The weight workbook publishes a different, explicit CCIF 2018 hierarchy. Both are retained verbatim and are never silently crosswalked.
