Reuse a replaced named comment's object reference so omitted replies and
review statuses remain attached. Keep popup replacement behavior and let
the final duplicate record control its deferred reply relationship.
Resolve indirect names in existing PDF comments so updates match their
original objects instead of creating duplicate parents.
Cover existing-PDF updates, incremental and full saves, subsequent FDF
exchange, page-scoped names, unnamed additions, duplicate records and
indirect names with surviving reply and review-status references.
