From the OP:
This is incidentally a good thing during the trial period because I am deciding whether to migrate from Pages. Apple’s conflict resolution is to pop up an alert; there is no utility to compare versions. When the file is 100,000 words long, such a simple-minded notification is untenable.
So the question to L&L is about a conflict in Scrivener, but a conflict in Pages is why they’re trying Scrivener at all. Hence my response to your note.
I originally asked this of Scrivener support, but received no response. I checked junk mail.
I am trialing the macOS product and have bought the iOS version. I use it on iPhone, iPad, and macOS, and am planning on using it on Windows, too. All with the same project. I am a novelist. To be clear, I write on whatever device is available at the time, usually editing on the iPhone, composing on the iPad, and doing some research and some writing on the Mac.
I managed to cause a conflict between edited versions. (I end up doing this every few days.)
This is the original post up to the mention of a conflict. The OP has not mentioned Pages at this point. I really think that they are talking about a conflict in Scrivener. If I misunderstood, I misunderstood.
Smaller files will synchronize more quickly, reducing the potential for conflicts in the first place. And only the one(s) that actually change(s) need(s) to be synchronized.
Scrivener was designed the way it is before synchronization was really a thing, but its project structure definitely fixes many of the challenges associated with having 100K+ words in a single file.
I really didn’t understand it in that way. If I misread, I apologise.
And the paragraph that I quoted – which is immediately after the ones you quoted – pretty clearly refers to a Pages conflict.
Perhaps the OP will clarify their remarks at some point.
Hope so. Just shows how easy it is for two people to read the same thing and interpret it completely differently. 
Yep. Best of both worlds. A Scrivener project feels like a novel in one file, but is little files handled behind the scenes.
Both products get sync conflicts. I bought Scrivener because Scrivener allows me to locate the conflicts by file comparison, and now with a genius procedure shared in this very thread. Pages leaves you hanging with no way to compare versions.
I think that L&L can make Scrivener better by hooking their snapshot comparator automatically into conflict documents. Why isn’t a conflict document also a snapshot in the original document, yet? Probably because iOS doesn’t handle snapshots? Heavy users of syncing, especially with iOS in the mix, will get conflicts.
Thanks for clarifying.
Best of luck with the novels
