Canonical Data Model (CDM)

The CDM is the backbone of Fastlane's configuration system. It defines a base schema of fields (drivers, vehicles, coverage, contact, common) that can be overridden at multiple levels:

Base CDM → Carrier Override → LOB Override → State Override

Override resolution uses first-match specificity: carrier + LOB + state beats carrier + state beats carrier + LOB beats carrier beats base CDM.

Fields that use cdmPath pull options, defaults, and visibility from the CDM. Carrier flows also include hardcoded step pages and forms.
