Characterization
The signal presents as a short structured burst repeating with a pattern that resists periodic modeling. Attempts to triangulate the source place it, contradictorily, both within and beyond Sector Grey-9.
Interpretations (disputed)
Some analysts argue the structure encodes a counting sequence. Others maintain it is an instrumentation artifact. The record is retained without a settled conclusion.
