Further thoughts, which may help towards further analysis (either proving my main program wrong, or allowing a manual proof to be better constructed)

A couple of minor tidy-ups, and added a non-answer section to gather thoughts so far towards how it might be solved "properly"

Updated ready for undeletion following much more tweaks to the search program than I'd ever envisaged.

Further update - less progress than expected at last update, so will delete answer within 24 hours if no further progress.
