コントラクト

• assert RFC 4180 strict parsing raises CSV::MalformedCSVError on unescaped internal quotes and backslash quotes unless liberal_parsing is enabled
• assert disabling quotes requires quote_char: nil whereas quote_char: "" raises ArgumentError
• assert skip_blanks: true alone does not skip whitespace-only lines without strip: true
• assert nil_value and empty_value explicitly differentiate unquoted empty fields from quoted empty string fields
• assert CSV.generate with quote_empty: false emits unquoted empty fields instead of quoted empty strings
• assert field_size_limit raises CSV::MalformedCSVError when field length exceeds configured threshold
• assert skip_lines ignores rows matching pattern without raising syntax errors
• assert explicit row_sep: "\n" raises CSV::MalformedCSVError on CRLF data due to carriage return in unquoted fields
