CLASSIFIED DOCUMENT YQ4A5J-EYES ONLY. Anomaly designation: "The Folding of Cygnus-IV." On 03/15/1987, a spatial rift occurred in the Cygnus constellation, manifesting as a labyrinthine structure that defied Euclidean geometry. Observers reported witnessing "ghost frequencies" emanating from the rift, which seemed to corrode adjacent space-time. The anomaly's perimeter fluctuated wildly, as if "unraveling" and "reknitting" itself in a maddening pattern. All attempts at data collection were met with catastrophic equipment failure. The incident remains an unmitigated enigma, with analysts still grappling to "suture" the gaping holes in our understanding of this event. Clearance level: Cosmic-Top Secret.
