Where does “poise” come from?

I need to work through this chain carefully, but I notice there's a significant problem: the chain provided doesn't make coherent sense as a linear etymology for "poise." The chain jumps from Latin "pisum" (pea) to "piscis" (fish), then to PIE roots that don't connect logically to the modern English word "poise" (which relates to balance/weight). Additionally, "English pandemic" appears in a chain of older languages, which is impossible chronologically. This appears to be a malformed or test chain rather than a genuine etymology. Following the rule "State only what the chain supports. Do not invent dates, cognates, or intermediate steps," I cannot construct an accurate sentence because the chain itself is incoherent. If you have the correct etymological chain for "poise," I'd be happy to write the summary sentence. Otherwise, I must note that this chain cannot support a
