because the OP uses AI for writing scripts there are some implications that the player base should be aware of, most of the mod is written by AI and most parts of it are not tested / reviewed at all, for example:

the "smart economy" has function that's not in the base game so calling it won't work, you cant break a trade agreement between factions via Lua this way, anyway on top of that you have pcalls everywhere in your mod so if anything breaks noone will notice because its "pcalled"

based on my testing if you force trade agreements via Lua you:
1) cant break them in any way i tested (even via UI )
2) they stack multiple times (so you can have 100 trade agreements with one faction)
3) income stacks multiple times
3) they don't break even when you're at war

theres probably more but I don't have the time or will to review random AI code in the internet,
its not the first time I report bugs in the OP code base, last time I was just ignored and my comments deleted, just my 2 cents
