 - [v1.1 Roadmap]: Phase 5 consolidates waveform types (WAVE-01, WAVE-02) with bank decoupling — both are internal refactors with no user-visible surface, establishing the injectable seam before config is added
 - [v1.1 Roadmap]: Research steps 5+6 (wire config + freq/waveform overrides) collapsed into Phase 6 — they share the same integration boundary (encode.RunSynthesis signature change) and are safer to land together
 - [v1.1 Roadmap]: User class name collision with built-in TrafficClass strings is an unresolved design question — decide before coding Phase 7 (treat as override vs. reject as ambiguous)
+- [Phase 05]: FreqConfig struct uses named field syntax for ClassFreqConfigs entries (required by WaveformType addition)
+- [Phase 05]: WaveformType zero value is WaveformCustom — all 14 existing ClassFreqConfigs entries retain hand-tuned harmonics without modification
