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.
