Nope, that doesn't do it, because using Torf ,fort, or Tor 4 produces a solution. My doubt is whether a digit can be inserted where there could be a word, but not one that produces a solution.

I haven't rigorously examined the sample solutions for lack of one that would establish the point, nor do I really care to.

    Well. I think it is perfectly clear. You cannot use a digit at any point where a word is available. (*)

    (*) I was about to add 'regardless of whether a solution can be achieved', but it is unnecessary. If there is a word available, you cannot ignore that word and use a digit. For any reason, including achieving a solution that would otherwise be complient.

    For the record, without that rule, there would be many more solutions that are presented in the official results.

      Well, you've rewritten the requirement to avoid the problematic "can", but that you did so, rather than argue that "can" is not ambiguous, just shows that "can" is unambiguously ambiguous :)

      Would the sample provided in the spec have any additional solutions? If not, this falls into the category of ambiguities remaining after "all ambiguities" are resolved by the sample.
