Entity-level semantic merge driver for Git. Two agents edit different functions in the same file? Clean merge. Every time.
# Two agents edited different functions $ git merge feature-b CONFLICT (content): Merge conflict in src/lib.ts Automatic merge failed. # Git sees overlapping lines. # The functions don't actually overlap.
# Same merge, with weave configured $ git merge feature-b weave [src/lib.ts]: 2 entities matched, 2 modified, 0 conflicts Merge made by the 'ort' strategy. # Different functions = no conflict.
