Phase 6: Config Package and Sound Overrides Verification Report

Phase Goal: Users can create a TOML config file to override frequency and waveform per traffic class, with auto-discovery, partial override semantics, and clear validation errors Verified: 2026-03-26T20:15:00Z Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	Load with explicit path to valid TOML returns merged config map with overrides applied	✓ VERIFIED	TestLoadPartialOverrideFrequency, TestLoadBothOverrides — PASS
2	Load with no config file found returns default ClassFreqConfigs unchanged	✓ VERIFIED	TestLoadNoConfig (t.Chdir to empty tmpdir) — PASS
3	Load with unknown TOML key returns error naming the bad key	✓ VERIFIED	TestLoadUnknownKey ("frequncy") — PASS; error contains the typo'd key name
4	Load with partial override (only frequency set) leaves waveform unchanged	✓ VERIFIED	TestLoadPartialOverrideFrequency — WaveformType remains WaveformCustom — PASS
5	Load with partial override (only waveform set) leaves frequency unchanged	✓ VERIFIED	TestLoadPartialOverrideWaveform — BaseHz remains 65.0 — PASS
6	Load with unknown class name logs warning and does not error	✓ VERIFIED	TestLoadUnknownClass (BOGUS class) — err == nil, 14 entries, warning to stderr — PASS
7	User passes --config /path/to/file.toml and tool uses that file for sound overrides	✓ VERIFIED	config.Load(configPath) called in run() at line 87; flows to RunSynthesis and NewBank
8	User passes --config /nonexistent.toml and tool exits with clear error before capture	✓ VERIFIED	Tested live: go run ./cmd/netsynth --config /nonexistent/file.toml exits 1 with "config file not found: /nonexistent/file.toml"
9	User runs without --config and auto-discovery kicks in (or defaults used silently)	✓ VERIFIED	discoverPath() checks ./netsynth.toml then XDG dir; silent default on no-find
10	RunSynthesis uses the merged config map instead of hardcoded ClassFreqConfigs	✓ VERIFIED	encode/mp3.go line 58: synth.NewBank(1.0, freqCfgs) — no reference to ClassFreqConfigs

Score: 10/10 truths verified

Required Artifacts

Artifact	Expected	Status	Details
config/config.go	Load function, parse, validate, merge, discover	✓ VERIFIED	184 lines; exports Load, SoundOverride, rawConfig; all functions present
config/config_test.go	Table-driven tests for CFG-01 through CFG-05	✓ VERIFIED	181 lines; 9 test functions (TestLoad*); all 9 pass
cmd/netsynth/main.go	--config flag, config.Load call, freqCfgs to RunSynthesis	✓ VERIFIED	configPath var, flag registration, config.Load at line 87, two RunSynthesis call sites updated
encode/mp3.go	RunSynthesis with freqCfgs parameter	✓ VERIFIED	Signature: func RunSynthesis(..., freqCfgs map[classify.TrafficClass]synth.FreqConfig) error
encode/mp3_test.go	Updated tests for new RunSynthesis signature	✓ VERIFIED	Three call sites pass synth.ClassFreqConfigs as third arg

Key Link Verification

From	To	Via	Status	Details
config/config.go	synth/config.go	synth.FreqConfig, ClassFreqConfigs, WaveformPresetHarmonics	✓ WIRED	grep confirmed all three at lines 46, 147-148, 172, 178
config/config.go	classify/types.go	classify.TrafficClass (AllClasses implied)	✓ WIRED	Line 161: classify.TrafficClass(className) confirmed
config/config.go	github.com/BurntSushi/toml	toml.DecodeFile, md.Undecoded()	✓ WIRED	Lines 104 and 115 confirmed; dependency in go.mod
cmd/netsynth/main.go	config/config.go	config.Load(configPath)	✓ WIRED	Line 87: freqCfgs, err := config.Load(configPath)
cmd/netsynth/main.go	encode/mp3.go	encode.RunSynthesis(snapshots, outputPath, freqCfgs)	✓ WIRED	Lines 157 and 225 — both runLiveMode and runPcapMode
encode/mp3.go	synth/bank.go	synth.NewBank(1.0, freqCfgs) using passed-in config	✓ WIRED	Line 58: synth.NewBank(1.0, freqCfgs) — no hardcoding

Data-Flow Trace (Level 4)

Artifact	Data Variable	Source	Produces Real Data	Status
config/config.go	result map	synth.ClassFreqConfigs + TOML overrides	Yes — copies from ClassFreqConfigs (14 entries), overlays TOML	✓ FLOWING
encode/mp3.go	freqCfgs	Injected from config.Load	Yes — passed in from caller, not hardcoded	✓ FLOWING
cmd/netsynth/main.go	freqCfgs	config.Load(configPath) return	Yes — real config.Load result, error-guarded	✓ FLOWING

Behavioral Spot-Checks

Behavior	Command	Result	Status
--config flag appears in CLI help	go run ./cmd/netsynth --help	--config string Path to TOML config file (default: auto-discover)	✓ PASS
Explicit --config missing file errors before capture	go run ./cmd/netsynth --config /nonexistent/file.toml --read /dev/null	exit 1, "config file not found: /nonexistent/file.toml"	✓ PASS
All 9 config package tests pass	go test ./config/... -count=1 -v	All 9 TestLoad* PASS	✓ PASS
Full test suite green	go test ./... -count=1	7 packages all ok	✓ PASS
Binary builds and vets clean	go build ./... && go vet ./...	BUILD OK, VET OK	✓ PASS

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
CFG-01	06-01	User can create a TOML config file that overrides default sound mappings	✓ SATISFIED	config.Load + merge; TestLoadPartialOverrideFrequency PASS
CFG-02	06-01	Tool auto-discovers config from ./netsynth.toml or ~/.config/netsynth/config.toml (silent if absent)	✓ SATISFIED	discoverPath(); TestLoadNoConfig PASS (t.Chdir to empty dir)
CFG-03	06-02	User can specify explicit config path via --config flag (error if missing)	✓ SATISFIED	--config flag registered; config.Load returns "not found" error
CFG-04	06-01	User can override individual values without replicating entire default config	✓ SATISFIED	Pointer fields (*float64, *string); TestLoadPartialOverrideWaveform PASS
CFG-05	06-01	Unknown keys in config file produce a clear error with the typo'd key name	✓ SATISFIED	md.Undecoded() + keyPath extraction; TestLoadUnknownKey PASS

All 5 requirement IDs from both PLAN frontmatter entries (CFG-01, CFG-02, CFG-04, CFG-05 from 06-01; CFG-03 from 06-02) are satisfied with evidence.

Orphaned requirements check: REQUIREMENTS.md traceability table maps CFG-01 through CFG-05 to Phase 6. All 5 are claimed and verified. No orphans.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
go.mod	14	BurntSushi/toml marked // indirect despite being a direct import in config/config.go	Info	None functional — go mod tidy corrects it; does not affect build or tests

No placeholders, stub functions, hardcoded empty returns, or TODO markers found in any phase 6 modified files.

Human Verification Required

No items require human verification. All functional behaviors were confirmed programmatically:

• Config loading, merging, and validation verified via unit tests.
• CLI flag confirmed in help output.
• Error-before-capture behavior confirmed via live CLI invocation.

Gaps Summary

No gaps. All 10 observable truths verified, all 5 artifacts substantive and wired, all 6 key links confirmed, all 5 requirements satisfied. The single info-level finding (BurntSushi/toml marked indirect in go.mod) is a trivial go module hygiene item — go mod tidy resolves it and it has no impact on correctness or functionality.
