Hopefully Robin has it saved somewhere. It was something similar to
what you have, with a repeated pattern of rules for each selma'o.

For example, if you want to erase "lo broda" and replace it with "re
lo broda".  "lo broda cu sa re lo broda cu brode".  The idea is that
SA doesn't just look at the following word to know how far back to
delete, but to the folowing construct. I sill think this is only
marginally better than the selmaho version though.

Yes, but first we need to know what the correct behavior is supposed to be.

SU is used when you are getting nowhere with your utterance and you
want to make a fresh start. That's a reasonable thing to have, and
easy for the human parser to handle. SI is used to replace the last
word with something else. Somewhat artificial, but at least clear
enough and not impossibly hard to follow. But what do we want SA to
do? Searching back for the last appearance of some particular selmaho
in speech is an extremely hard thing to do, and then on top of that
you have to start reprocessing from there, keeping what you had before
and continuing with something else? That may work for machines, but
for human beings? In my opinion, that's the issue we have to solve for
SA before working out the grammar in detail. Selmaho driven
replacement is not a human friendly option, in my opinion.
