The metadata field on a OnboardingMilestone record in Skarn Suite (the platform auth hub: SSO, tenancy, billing, entitlements, internal event bus) stores a specific piece of the data; it stores structured data the application reads and writes here, holding richer per-record detail that screens unpack into readable information. In everyday use this is part of how OnboardingMilestone records are created, displayed, validated, and reported, and it is grounded strictly in the real schema fact OnboardingMilestone.metadata: Json.
