 **Phase 6 complete 2026-03-26:** TOML config system added. Users can override frequency and waveform per traffic class via `netsynth.toml` (auto-discovered or `--config` flag). Partial overrides, unknown-key validation, and fail-fast startup errors. New `config` package with BurntSushi/toml.
 
+**Phase 7 complete 2026-03-26:** User-defined classification rules via `[[rules]]` TOML blocks with port/protocol/class fields. User rules prepend before built-ins (first-match-wins). Auto-frequency assignment (FNV-32a, 1200-2350 Hz) for new class names. `--print-config` flag outputs full effective config as commented TOML with source annotations.

-- Custom waveform per class (sine, square, sawtooth, triangle)
-- User-defined classification rules with custom sounds
-- Auto-discover config from ./netsynth.toml or ~/.config/netsynth/config.toml
