- Load() discovers, parses, validates, and merges TOML config over defaults
- SoundOverride struct with *float64/*string pointer fields for partial-merge (CFG-04)
- parseFile uses BurntSushi/toml DecodeFile + Undecoded() for unknown-key errors (CFG-05)
- discoverPath probes ./netsynth.toml then ~/.config/netsynth/config.toml (CFG-02)
- merge applies non-nil overrides per class; warns on unknown class names (D-09)
- parseWaveform maps sine/square/sawtooth/triangle strings to WaveformType
- Harmonics regenerated via WaveformPresetHarmonics when waveform/frequency changes
- All 9 tests pass; go vet clean
- WaveformType int with five constants: WaveformCustom (0), WaveformSine,
WaveformSquare, WaveformSawtooth, WaveformTriangle
- WaveformPresetHarmonics generates bandlimited harmonic series for each type
- WaveformCustom returns nil to preserve existing hand-tuned harmonics
- All generated harmonics are below Nyquist (sampleRate/2)
- FreqConfig gains WaveformType field (zero value = WaveformCustom)
- ClassFreqConfigs converted to named fields (required for new struct field)
- All existing synth tests continue to pass (38 tests total)
- Add bpfFilter and readPath global vars with flag registration
- Add deriveOutputPath helper: capture.pcap -> capture.mp3 (D-05)
- run() validates mutual exclusion of --read and -i (D-03)
- run() pre-validates BPF filter via capture.ValidateBPFFilter before capture (CAPT-05)
- runLiveMode: extracts existing live pipeline, passes bpfFilter to StartCapture
- runPcapMode: reads pcap with ReadPcapFile, classifies with timestamps, AggregatePcap, encodes
- Bookend messages: 'Reading <file>...' at start, 'Saved...' at end (D-06)
- --verbose supported in pcap mode via onSnapshot callback (D-07)
- Empty pcap produces clear error with file path (Pitfall 4)
- Add AggregatePcap to aggregate/window.go: reads ClassifiedPackets from channel,
assigns to time windows using Timestamp field (D-01), fills gaps with empty
snapshots (D-02: silence), fires onSnapshot callback per window (D-07)
- Add 7 tests covering basic, multiple windows, gaps, empty input, WindowIndex,
class counts, and onSnapshot callback
- All tests pass
- Add Timestamp time.Time field to ClassifiedPacket (classify/types.go)
- Create capture/bpf.go: ValidateBPFFilter and CompileSoftwareBPF
- Create capture/pcap_reader.go: ReadPcapFile with optional software BPF filter
- Update OpenCapture and StartCapture to accept filter string param
- Update cmd/netsynth/main.go to pass empty filter to StartCapture
- All new tests pass; existing tests unaffected
- Add 03-01-SUMMARY.md with deviations and test results
- Update STATE.md: advance progress, record metrics and decisions
- Update ROADMAP.md: phase 3 plan progress
- Mark CLAS-02 requirement complete
- Replace ClassUnknown with ClassUnknown1-4 (unknown-1 through unknown-4)
- AllClasses() now returns 14 elements
- Add hashBucket() function routing unrecognized traffic deterministically
- Update synth/config.go: NumLayers=14, 4 dissonant unknown tone configs at 862-1047 Hz
- Add TestAllClassesCount and TestHashBucketDistribution tests
- Add TestClassFreqConfigsComplete and TestNumLayersMatchesAllClasses to config_test.go
- Update TestNewBankHas14Layers, TestMixerNoClip for 14 classes
- All classify and synth tests pass
