basic XBYTE questions

I've been spinning my wheels here for too long. I've had more code and less code and it has executed byte_codes and lut_tables and not yet in a way I expect and often forever executing them. I baked this down to the what I think are the essential elements to run a few byte codes. baby steps, I'll try to build on.
ultimately, I'm trying to launch this cog with the byte_codes required to load a Scheme parser/bytecode generator that continues to load the XBYTE interpreter. I've noodled around with starting two adjacent cogs to share a double-sized LUT to cover most of R5RS Scheme bytecodes implemented in Pasm2.
all that may be a fever dream of mine. but, I was hoping someone here would recognize the mistakes I've made in this condensed batch of mistakes, and help me grok what needs to happen. as nifty as it is in other respects, grok.com couldn't help me with this.
I welcome any guidance, comments, even chiding. thanks.
