i do not remember if they asked, but i had all my application paper with me going thru immigration. If your insurance expire on dec 31 2025 than you will only be stamped until your insurance expire, so not 1 full year. I also lost 2 months when initially entered due to insurance.
So what you can do, before your stamp expire buy new insurance for 1 yr in Thailand, leave Thailand - go vacation somewhere close ie Singapore, Malaysia...etc. once you come back provided the same visa and new insurance to immigration. They will stamp you for another year the expiration date of yr new insurance.
This was what i did for the initial 2 yrs.
