# Phase 8: Test and Constant Cleanup Verification Report
|
||
|
|
|
||
|
|
**Phase Goal:** Pre-existing test assertions and a stale exported constant that would block or mislead all subsequent v1.2 work are removed
|
||
|
|
**Verified:** 2026-03-27
|
||
|
|
**Status:** passed
|
||
|
|
**Re-verification:** No — initial verification
|
||
|
|
|
||
|
|
## Goal Achievement
|
||
|
|
|
||
|
|
### Observable Truths
|
||
|
|
|
||
|
|
| # | Truth | Status | Evidence |
|
||
|
|
|---|-------|--------|----------|
|
||
|
|
| 1 | NumLayers and GainPerLayer constants do not exist in the synth package | VERIFIED | `grep -n "NumLayers\|GainPerLayer" synth/config.go synth/bank.go synth/config_test.go` returns zero matches (exit 1 = no matches) |
|
||
|
|
| 2 | `go test ./...` passes with zero failures after all edits | VERIFIED | All 7 packages green: aggregate, capture, classify, cmd/netsynth, config, encode, synth |
|
||
|
|
| 3 | TestFrequenciesInRange accepts any BaseHz in (0, Nyquist) without manual test surgery | VERIFIED | `const nyquist = float64(synth.SampleRate) / 2.0` at line 19; hardcoded `1100` bound absent (grep returns exit 1); test passes |
|
||
|
|
| 4 | TestNumLayersMatchesAllClasses is renamed to TestClassFreqConfigsMatchAllClasses | VERIFIED | `TestClassFreqConfigsMatchAllClasses` present at line 56; `TestNumLayersMatchesAllClasses` absent; `TestClassFreqConfigsComplete` absent |
|
||
|
|
|
||
|
|
**Score:** 4/4 truths verified
|
||
|
|
|
||
|
|
### Required Artifacts
|
||
|
|
|
||
|
|
| Artifact | Expected | Status | Details |
|
||
|
|
|----------|----------|--------|---------|
|
||
|
|
| `synth/config.go` | Cleaned constant block without NumLayers or GainPerLayer; contains WhisperFloor | VERIFIED | Constant block contains SampleRate, WindowMs, SamplesPerWindow, WhisperFloor only (lines 5-10). NumLayers and GainPerLayer absent. |
|
||
|
|
| `synth/config_test.go` | Future-proof test assertions; contains TestClassFreqConfigsMatchAllClasses | VERIFIED | Nyquist-based validation in TestFrequenciesInRange (line 19). TestClassFreqConfigsMatchAllClasses present (line 56). TestClassFreqConfigsComplete absent. |
|
||
|
|
|
||
|
|
### Key Link Verification
|
||
|
|
|
||
|
|
| From | To | Via | Status | Details |
|
||
|
|
|------|----|-----|--------|---------|
|
||
|
|
| `synth/bank.go` | `synth/config.go` | gainPerLayer computed dynamically in NewBank — no static constant conflicts | VERIFIED | `gainPerLayer: 1.0 / float64(len(cfgs))` at line 21 of bank.go; no reference to the deleted NumLayers constant anywhere in synth package |
|
||
|
|
| `synth/config_test.go` | `synth/config.go` | TestFrequenciesInRange validates BaseHz against SampleRate-derived Nyquist | VERIFIED | `float64(synth.SampleRate) / 2.0` at line 19 of config_test.go; test runs and passes |
|
||
|
|
|
||
|
|
### Data-Flow Trace (Level 4)
|
||
|
|
|
||
|
|
Not applicable. This phase modifies a constants file and test file only — no dynamic data rendering involved.
|
||
|
|
|
||
|
|
### Behavioral Spot-Checks
|
||
|
|
|
||
|
|
| Behavior | Command | Result | Status |
|
||
|
|
|----------|---------|--------|--------|
|
||
|
|
| TestFrequenciesInRange passes | `go test ./synth/... -run TestFrequenciesInRange -count=1` | PASS | VERIFIED |
|
||
|
|
| TestClassFreqConfigsMatchAllClasses passes | `go test ./synth/... -run TestClassFreqConfigsMatchAllClasses -count=1` | PASS | VERIFIED |
|
||
|
|
| Full suite green | `go test ./...` | All 7 packages ok | VERIFIED |
|
||
|
|
| Both task commits exist | `git show --stat fd17061 4800e8e` | Both commits present with correct file changes | VERIFIED |
|
||
|
|
|
||
|
|
### Requirements Coverage
|
||
|
|
|
||
|
|
| Requirement | Source Plan | Description | Status | Evidence |
|
||
|
|
|-------------|------------|-------------|--------|----------|
|
||
|
|
| CLEAN-01 | 08-01-PLAN.md | Remove stale NumLayers constant and hardcoded frequency range test assertions that would block new class additions | SATISFIED | NumLayers and GainPerLayer deleted from synth/config.go (commit fd17061); hardcoded 1100 Hz bound replaced with Nyquist-based validation in config_test.go (commit 4800e8e) |
|
||
|
|
|
||
|
|
**Orphaned requirements check:** REQUIREMENTS.md maps only CLEAN-01 to Phase 8. The plan declares CLEAN-01. No orphaned requirements.
|
||
|
|
|
||
|
|
### Anti-Patterns Found
|
||
|
|
|
||
|
|
| File | Line | Pattern | Severity | Impact |
|
||
|
|
|------|------|---------|----------|--------|
|
||
|
|
| — | — | None found | — | — |
|
||
|
|
|
||
|
|
No TODOs, FIXMEs, placeholders, empty returns, or stub indicators in the modified files.
|
||
|
|
|
||
|
|
### Human Verification Required
|
||
|
|
|
||
|
|
None. All phase deliverables are code-verifiable (constant deletion and test assertions checked programmatically).
|
||
|
|
|
||
|
|
### Gaps Summary
|
||
|
|
|
||
|
|
No gaps. All four must-have truths are verified against the actual codebase:
|
||
|
|
|
||
|
|
- `synth/config.go` constant block contains exactly SampleRate, WindowMs, SamplesPerWindow, and WhisperFloor — the two stale constants are gone.
|
||
|
|
- `synth/config_test.go` uses Nyquist-derived bounds (22050 Hz) with no hardcoded 1100 Hz upper limit — adding a new class at any frequency up to 22050 Hz requires no test edits.
|
||
|
|
- The old `TestNumLayersMatchesAllClasses` name is gone; `TestClassFreqConfigsMatchAllClasses` replaced it with identical body.
|
||
|
|
- The duplicate `TestClassFreqConfigsComplete` is removed.
|
||
|
|
- All 7 packages pass `go test ./...` with zero failures.
|
||
|
|
|
||
|
|
The phase goal is fully achieved: no stale constants or hardcoded test bounds remain to block v1.2 work.
