# Code Review — TP-045 Step 3

**Verdict:** APPROVE for the Step 3 code change, with one non-code cleanup noted below.

## Findings

### P3 — Strip trailing whitespace from the newly added Step 3 plan review

`git diff --check 3d0dd1fcf58c3a799b1aeaf7dcac74f8fdec938b..HEAD` fails on trailing whitespace in `taskplane-tasks/TP-045-intervals-client-dojsonquery-hardening/.reviews/R006-plan-step3.md` lines 9, 12, 15, and 18. This is not a production-code issue, but it is in the current diff and may break whitespace checks if enforced. Remove the Markdown line-ending spaces before merge.

## Code review notes

No blocking code findings for `RetryConfig.WithDefaults`.

The implementation replaces `normalizeRetryConfig` at the `NewClient` call site and in the direct test helper construction, deletes the old function, and avoids the whole-struct `RetryConfig{}` comparison. The explicit `allFieldsUnset` calculation is captured before defaults are applied, preserving the existing retry semantics:

- zero `RetryConfig{}` receives default attempts, base delay, max delay, and default jitter;
- partial configs such as `RetryConfig{MaxAttempts: 3}` keep explicit zero jitter;
- non-positive attempts/base/max delays still default;
- negative jitter is still clamped to zero.

The exported `WithDefaults` method has a doc note starting with the identifier, so it should satisfy the exported-note lint rule.

## Verification run

- `go test ./internal/intervals` — pass
- `go test ./...` — pass
- `git diff --check 3d0dd1fcf58c3a799b1aeaf7dcac74f8fdec938b..HEAD` — fails only on the trailing whitespace in `R006-plan-step3.md` noted above
