The record

An official file preserves that a report was made and examined. It does not, by itself, establish what was seen.

UNKNOWN - described at https://www.theufochronicles.com/2005/12/kgbs-secret-ufo-files-finally-made.html

No document is attached yet. The retrieval is open work.

What is not settled

The Blue Folder's chain of custody is bad: the pages reportedly vanished, a Swedish journalist is said to have bought them in Russia for 500 German Marks, and copies bearing KGB registration marks were distributed by a ufologist. No independent verification against a Russian state archive has been published, and the KGB has a documented history of seeding UFO disinformation.
