# R019 code review — Step 4: Tests and verification

Verdict: REVISE

Targeted tests pass with:

```sh
go test -count=1 ./internal/analysis ./internal/tools ./internal/toolcatalog ./internal/toolchecks ./internal/safety ./cmd/gendocs
```

## Blocking findings

### 1. New test helper is unused and will fail lint

- Location: `internal/tools/compute_tools_test.go:584`
- Severity: Medium

`ptrFloat64` is added in this step but is never referenced. The repo enables the `unused` linter with tests included, so this will fail the Step 5 lint gate. I confirmed `golangci-lint run ./internal/tools` reports:

```text
internal/tools/compute_tools_test.go:584:6: func ptrFloat64 is unused (unused)
```

Remove the helper or use it in a fixture before marking Step 4 complete.

## Notes

`golangci-lint run ./internal/tools` also reports existing implementation lint issues outside this Step 4 diff (`unparam` in compute helpers and unused implementation helpers). Those are not introduced by this test-only change, but they will also need resolution or documentation in Step 5 if still present.
