+- 状态：DONE
+- 变更：新增 `contract/jkda.go` 与 `contract/jkda_test.go`；按 `docs/04 §8` 建立 `FindHealthRecordResponse`、`FindHealthRecord`、`HealthRecord`、`PastHistory`、既往疾病/手术/外伤/输血数组和 `FamilyMiddle` 查询响应结构体；保留响应侧错拼字段 `adressNumber`；`checkId`、`insuranceType`、`otherPersonGroup` 等 nullable 字段使用指针。
+- 验证：按 TDD 先看到 `go test ./contract -run TestFindHealthRecordDeserializesMeasuredJKDA00002Data -count=1` 因 `FindHealthRecord` 未定义失败；补结构体后通过。随后看到 `go test ./contract -run TestFindHealthRecordResponseDeserializesDataArray -count=1` 因 `FindHealthRecordResponse` 未定义失败；补响应结构体后通过。最终 `go test ./contract -count=1` 通过，`go test ./...` 通过。
