Sequential consistency.
also: sequentially consistentEvery node sees all operations in the same order, each client's in its own program order, though not necessarily in real-time order.

- Weaker than linearizable, still one global order.
- A write may become visible 'late' compared with the wall clock, but everyone agrees on the order.
- Each client's own operations stay in the order it issued them.
