Written for someone who has never seen the pre-split extension: what the plugin adds to Nemo, what it costs, every config key, and the exact steps to move over from the single file version or go back.
Everything that was not about drawing emblems moves out: the columns, the properties tab and the context menu are their own plugins now, and the config, git and cache layers come from nemo-repo-core.
The indicator list stops being hardcoded. Entries that are not one of the three git derived indicators are matched by marker_directory or marker_file, which is how claude_dir now works and how a user adds their own without touching the code.
