There was a problem hiding this comment.
Small nit on my part. Feel free to disregard.
Move this check to the top of the for loop. Alternatively make the models slice the same length as the modelStatus slice before the for loop and we can remove the defensive programming for each iteration.
Prevent a panic, ensure the index used on a slice isn't larger than the slice itself.
Help prevent a panic downstream.
