 "note": "Aggregate counts only. Grades describe the strength of evidence; they never name a perpetrator. deliberate_suspected needs an official notice reporting jamming or spoofing, or (from v1.1) EASA's weekly table listing spoofing in the FIR, covering a time-resolved effect (rule D1). EASA tables exist for only some weeks, so monthly deliberate_suspected counts follow which weeks have a table, not how much spoofing there was. The rules are frozen but not yet validated.",
