I'm not sure I completely understand your question, but I'll take a crack at it.

The Masoretes came up with their vowel notation method between the 8th and 12th centuries CE.

The Torah (Five Books of Moses) has very extensive rules around how it is written. A sopher (scribe) who writes a Torah must follow these rules. A Torah is prepared today exactly as it was in the days of Isaiah, David and Moses himself.

The 'nach (Prophets and Writings) was codified by the Men of the Great Assembly between 410 BCE and 310 BCE. This is about 1000 years before the first Masoretes.

All the Masoretes did (I say "all" but they did wonderful things to bring the oral tradition to written form) was add the vowel notations to make it easier for those less learned to read the text.

I'm not sure if I answered your question. If not feel free to ask it again!
