It's filesystem mapping 1:1. Basically the same thing Obsidian does when you open a vault. You can create new files with Reor, create directories and edit existing files. Chunking happens only in vector DB and everything is synced automatically so you shouldn't notice anything if you reopen Reor after using Obsidian. In short, yes it'd work seamlessly if you wanted to use it occasionally.
