Note: goreportcard.com was sunset this week, so the automated Go Report Card check can no longer fetch a grade for any submission. For reference, go-wav is clean under gofmt -s, go vet, and golangci-lint, has ~96% test coverage across the module, targets Go 1.26 with zero runtime dependencies, and ships a tagged v1.0.0 release.
