Reality does not make mistakes and that is why we strive for meaning. A justification for Meaning. I feel like most of your points are sugary, I mean, that you could have phrased it more simply.
I - I do exist. => means that you are aware of the fact that you can think. (the notion of existence is ambiguous)
II - Time exists => Things I see/think vary overtime. (You know that time exists because you see variation)
III - Reality can not make mistakes => Things that happen happen. (If I understood your concept of mistake properly (= an error from our thought system regarding our representation of the reality))
IV - There is a blueprint for reality => There is a set of universal rules. (I do not agree with that one, since it's affirmative.
However, I would agree with "There could be a set of universal rules".
I will agree to your own statement if you prove me that a set of universal rules is needed to keep a reality up.
Since we can only experience the world,
Rules are usually the name we give to "patterns we discovered in the reality", which means it's a way for us to state that something in the world seems (to our eyes) to be constant, happening repetitively.)
