This is the key point. Once your data structure carries the full edit history instead of reconstructing it from DAG traversal, rebase and merge become different views of the same operation. Not fundamentally different operations with different failure modes. The weave approach moves ordering into the data itself. That's the same insight that matters in any system that needs deterministic ordering across independent participants: put the truth in the structure, not in the topology of how it was assembled.
