## The brief

GitHub's external custom properties preview lets an outside system keep repository ownership, service tier or compliance context in sync. Values remain read-only in GitHub so the external integration stays in control. Teams can use that context in repository filters and rulesets, with either the initial Port.io integration or their own API integration.
