        moveOwnDuplicated:
          type: boolean
          description: >-
            Controls what happens when a submitted URL already exists in another
            active list of the same owner (any campaign, not just the current
            one). If `true`, the existing prospect record is moved into this
            list — the record itself (id, statistics, flags, connection data) is
            preserved and simply re-assigned, and the URL is counted in
            `submittedUrls`. If `false`, the URL is skipped and reported in
            `existedUrlsMap` keyed by the campaign where the duplicate lives.
            This flag has no effect in three cases the backend always handles
            automatically: (1) duplicates in a teammate's or another user's list
            — always reported in `existedUrlsMap`, never moved; (2) previously
            deleted duplicates of the same owner — always reactivated into the
            target list; (3) exact same-list duplicates — skipped silently.
        shouldBeDeletedIfInactive:
          type: boolean
          description: >-
            If `true`, auto-remove prospects who have no posts on LinkedIn
            within the last 30 days (checked once, when the backend first pulls
            their posts). If `false`, keep them regardless of recent posting
            activity.
