• Header comment references 'send.go' but the file is named 'parse.go'. Update the @title to match the actual filename.

// @Title        send.go

• [nitpick] Error message 'column key cannot be EMPTY' has inconsistent casing. Consider using 'column key cannot be empty' for clarity and consistency.

return ColumnDTO{}, errors.New("column key cannot be EMPTY")

.github/workflows/test-core.yml:16

• The workflow ignores the OS matrix and always runs on ubuntu-latest. Change to 'runs-on: ${{ matrix.os }}' to respect the configured matrix.

runs-on: ubuntu-latest

• [nitpick] The Name and Error fields (mapping from record.GetColumnName() and record.GetColumnError()) are not covered by tests. Consider adding test cases to validate these mappings.

Name:        record.GetColumnName(),
