Access Top Record within Repeaters

How do I access the top-record within repeaters?
I tried

fn (Contract $record) => dd($record)

fn (Contract $record) => dd($record)

and

fn (Contract $ownerRecord) => dd($ownerRecord)

fn (Contract $ownerRecord) => dd($ownerRecord)

I've like

– top-record
   - fieldset (relationship)
      - repeater
         - repeater

– top-record
   - fieldset (relationship)
      - repeater
         - repeater
