+# 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.
