Clarification of:
When attempting to read the database the standard library <map> throws std::out_of_range from "_NODISCARD mapped_type& at(const key_type& _Keyval)". _Keyval is 0.
The calling location is in reslut.h function "Value& get(col_count_t pos)". pos is 0. Line of code that throws: "return m_vals.at(pos);"
The exception is not fatal and the returned result (a pair of strings, one of which is a path to a file) works to open the file without error.

There are two calls per returned row, On first call _Keyval is 0, 1 on second call. Additionally, pos has the same value as _Keyval. For each row returnee there are two std::out_of_range exceptions.
