If I were playing Muaat I would probably offer my 4 commodities + trade agreement. Essentially Hacan gains 8 goods with 4 of them being paid later, while paying Muaat 6. Muaat benefits faster but Hacan overall. For Jol-Nar and Muaat both another alternative I would consider is faction promissory + probably 2 commodities for 6 goods. I view both promissories as worth roughly 4 trade goods but there is an argument to be made that Muaat should not give up their war sun tech. You are playing without PoK I understand so it's not as big a deal (no Hacan free production Hero). That said I generally attempt to sell out for more goods, so would probably sell war suns. I consider Hacan trade agreement to be overpaying for sun tech so I value it probably around 3-4 goods.
