Richard, thank you for your reply. I really appreciate it. The fact that you have carefully thought about how to cross the FROM clause barrier with expressions is itself a useful fact. If you say the current implementation is painted into a corner on this issue I believe you. It would be impossible to deduce this fact by simply studying documentation or source code. Thank you very much for taking my question.
At some point I may try what you suggest and see what I can learn. In the meantime, the CSV virtual table example appears to be closest to where I'd like to go next. https://sqlite.org/csv.html That example allows the caller to specify a creation schema. Expanding on the schema specifier, perhaps there is a way to make xBestIndex() and xFilter() work more generally in the problem domain of lightly encapsulated dynamic tables.
