+## Current Milestone: v1.2 Extended Protocol Coverage
+
+**Goal:** Expand traffic classification with grouped protocol families that share recognizable sound signatures
+
+**Target features:**
+- Research common network protocols and identify missing ones beyond the current 10
+- Group related protocols into families (Mail, Web, Remote Access, Database, Discovery, File Transfer, VoIP)
+- Within-group sound design: shared base frequency, different waveforms or slight detuning
+- Frequency rebalancing to accommodate new classes without overcrowding the spectrum
+- New classification rules for all identified protocols
+- Updated --print-config output reflecting groups
+
