# Code Review — TP-002 Step 2

## Verdict

APPROVE

## Findings

No blocking findings.

## Notes

- The client core stays within Step 2 scope: constructor/config plumbing, Basic Auth with `API_KEY` as username, per-request `User-Agent`, context-aware request creation, response body closure, and typed DTO definitions for the planned profile shape.
- `doJSON` currently has only temporary generic status handling, which is acceptable before Step 3. Structured/sentinel errors, retry behavior, and `Retry-After` support still need to be added in Step 3 as planned.
- Tests are not present yet, but Step 5 explicitly owns test coverage. Please ensure the later httptest coverage verifies auth header contents, user-agent, URL joining under a base path like `/api/v1`, body closure on non-2xx/decode paths, and secret-free errors.

## Verification

- Ran `git diff c154187b905da1d9b0c95aa7a503a3cdecf8d11d..HEAD --name-only`.
- Ran `git diff c154187b905da1d9b0c95aa7a503a3cdecf8d11d..HEAD`.
- Ran `go test ./...` — passed.
- Ran `git diff --check c154187b905da1d9b0c95aa7a503a3cdecf8d11d..HEAD` — no whitespace errors.
