Revision policy

Preserving history is part of the data.

This policy defines how BoliviaDB will treat corrections, revisions, replacements, and conflicts across releases.

The official source governs

BoliviaDB does not replace an official release. It preserves the source file and publication-date reference.

When a source changes values, the new version is published without deleting prior vintages where the product supports them.

Unit, scale, frequency, and aggregation changes are documented in metadata.

If official releases disagree, the series remains under review until the source hierarchy is resolved.
