I think the questions you propose are still too broad, although not as badly as the closed question you mention.
Latin evolving into Italian is a large phenomenon, and it would be better to ask about one specific thing at a time.
For example, something along the following lines would look good to me:
- Can you give two example texts, one written in Latin and one in early Italian that were written at almost the same time? Please indicate times and places for the texts and argue why one is Latin and the other is Italian. I would like to understand the transition from Latin to Italian via a concrete example.
- What are some early signs of regional dialects developing in Latin? I am mainly looking for regional properties that persist in some form in today's Romance languages. In other words, I want an early example of Latin starting to develop into its daughter languages.
- Did developments in medieval Latin influence Italian language in any way after the two languages were generally considered separate? If yes, can you give an example?
- This text is described as early Italian: <insert quote>. How can we argue that this text is no longer Latin?
In my opinion SE sites work much better via small(ish) concrete questions.
Even if you want to see a bigger picture, ask so that a good answer can be given concisely.
Often big pictures are best seen through examples and specific sub-questions.
