Versioning policy

CPS uses semantic versioning for the public dataset:

• Major: incompatible canonical-code, field, or interpretation changes.
• Minor: new families, references, collections, or backward-compatible fields.
• Patch: corrections that do not change the intended identity of a reference.

Published family numbers are permanent. New families are appended rather than inserted into the existing registry.

Migration behavior

Color Pick accepts supported legacy codes during input, project import, shared-state loading, and local-data migration. New exports use the current canonical code while retaining a legacy alias field when relevant.

Applications using a versioned dataset should pin the exact filename and review this page before upgrading.
