- [Phase 01-capture-and-classification]: Dynamic link type detection via handle.LinkType() not hardcoded LinkTypeEthernet
- [Phase 01-04]: Cobra RunE + signal.NotifyContext for clean shutdown: context cancellation is the single stop signal propagating through all three pipeline stages
- [Phase 01-04]: Three-stage pipeline: capture -> classify goroutine -> aggregate via buffered channels; 1024-buffered classified channel absorbs burst processing
- [Phase 02]: go-lame v0.0.9 used for MP3 encoding (embedded LAME C source, no system library needed)
- [Phase 02]: go-audio/wav excluded — writing PCM bytes directly to LameWriter is simpler (per Claude's Discretion grant in CONTEXT.md)
