This directory should contain code related to affiliation, a mechanism that determines if user and device are managed by the same organization.
Managed users and managed devices can have affiliation IDs that were set by their admin. When the device and the logged in user are both managed and have a matching affiliation ID, they are said to be affiliated. This influences the behavior of some policies that only apply in the affiliated or the unaffiliated case.
TODO(crbug.com/40185259): Add more information about affiliation.
