"The teachings of Sacred Magisterium are given on a solemn occasion and are infallible dogma. They are proclaimed at councils."

I appreciate your patience. I had already looked at wikepedia but they really didn't have a lot of info.

If I get it, when a council is called the findings of that council are then dated, published and considered findings of the magesterium. IOW, the Nicene Council was a meeting of the magesterium. If for example it's an ordinary finding this could be developed by letters sent from one bishop to the next until every one has had their say, if they want to, and when there is an agreement there is a finding.

Yes, except if the two bishops have any reason to suspect that they teaching is not common to all, they would probably check with the curia (The Court in Rome) as well.
