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

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 |

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.
