# 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

### 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.
