What the Protocol Is
The Null Protocol does not exist. This is the official position of the Sovereignty of Solara, maintained in every public record, every press briefing, and every official response to every inquiry from every foreign government, independent journalist, and citizen petition that has ever asked about it.
The Null Protocol is the Sovereignty's black directorate for Voidshaper management. It locates Voidshaper-sensitive individuals across the galaxy, conducts covert assessments of their capabilities and threat profiles, and "contains" those assessed as high-priority. What containment means is determined by the Director on a case-by-case basis. It has never meant execution. Whether this is because of ethical constraints or operational pragmatism depends on who you ask.
The Protocol's budget is buried under fourteen layers of classified appropriations drawn from nine different administrative departments. No single Sovereignty official outside of the Director's clearance level can see the full funding picture. The Grand Council has voted to investigate it three times in the last decade. Each investigation was classified before it began. This is not unusual. This is, in fact, the Protocol doing exactly what it was designed to do.
