How it works: Suture performs a three-way merge using the common ancestor (Base). It detects changes from both sides and resolves non-overlapping edits automatically. When both sides modify the same region differently, it inserts conflict markers so you can resolve manually. JSON merges operate at the field level — different keys never conflict.
