Detection
Signal Analysis logged the fifth occurrence of the recurring interval pattern first catalogued under ARC-0001. The gap between the fourth and fifth cycles was roughly sixty percent of the gap between the third and fourth, a shortening trend flagged for continued monitoring rather than immediate escalation.
Cross-Department Note
Pattern Analysis was formally looped into Signal Analysis's review for the first time on this record, at the request of a department head who noted structural similarities to material logged under the Silent Ocean designation.
