Correct me if the detail matters more than I have assumed.

Adding the part of the answer the thread has not reached. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

OP back with an update, since a thread like this is useless without one.
