1. Seems that you fixed only indentation. Please, fix other comments too.

2. You do not need rights, when work locally.

3. Please, do not put a code in comment. If you do not need it, then just delete.

> +subscriber:replace({1, 1, '79160000000', 42})
> +t = subscriber:get({1, 1})

4. replace() returns a result tuple, so you can just do t = subscriber:replace(), with no get().

> +t:tomap({names_only = false})
> +t:tomap({names_only = true})

5. Like I wrote in the previous review, please, add tests on tomap with invalid options, on tomap with names_only = non-boolean, on tomap with empty options. Do not hurry so much.
