# Code Review — TP-065 Step 3

Result: APPROVE

## Findings

No blocking findings.

## Notes

- The requested `git diff 1acec90ecc5492c7ca80dac3e5342f2998aaacd8..HEAD` was empty because the supplied baseline commit is the current `HEAD`. I reviewed the Step 3 implementation via `git diff 1acec90ecc5492c7ca80dac3e5342f2998aaacd8^..1acec90ecc5492c7ca80dac3e5342f2998aaacd8`.
- The split is mechanical: encoder code moved to `internal/response/jsonenc`, walker code to `walk.go`, shaping API/pipeline to `shape.go`, metadata enrichment to `meta.go`, and `RegisteredScaleLabels` to `scales.go`.
- Public `internal/response` API remains unchanged (`Options`, `Shape`, `SetRuntimeCatalogMetadata`, `RegisteredScaleLabels`).

## Verification

- `go test ./...` passed.
- `git diff 1acec90ecc5492c7ca80dac3e5342f2998aaacd8^..1acec90ecc5492c7ca80dac3e5342f2998aaacd8 --check` passed.
- `gofmt -l` on the touched response files produced no output.
