Answer
Lane priorities, expiration times, and entanglement rules ensure predictable update ordering.
Quick Answer
React's lane model assigns each update to a specific bit in a lane bitmask (32-bit integer). Each lane represents a priority level. React processes lanes in priority order. Because lanes are bitmask operations (fast) and priorities are fixed, React can deterministically schedule and merge concurrent updates — the result is always the same for the same inputs.
