Research direction

Start in api/provisioning.go around lines 1762-1792 and inspect the surrounding provisioning function and its handling of configlets. Review the range-loop pointer finding and determine whether the reassignment affects the intended reconciliation behavior; done means the finding is resolved or documented with the expected behavior verified.
