The protocol hung off whatever frame the renderer happened to be drawing, and the only thing standing in for synchronisation was the sum of every vehicle's coordinates with a random number added on top - a value that cannot be equal on two machines and therefore reported a desync on every single step. - Global.simulation_tick: the authority counts the steps, a client takes the number from the authoritative frame it is executing. FRAME_INFO and the command requests carry it, so the network timeline has one unambiguous order independent of frame rates - network/statehash: a versioned FNV digest of the gameplay critical state - vehicle position, speed, direction, brake pipe and cylinder pressure, plus the clock. Values are quantized so that float noise is not mistaken for drift, and vehicles are folded in under their own identity and summed, so the digest does not depend on the order the scenario created them in. Switches, memcells and the event queue are the next candidates; they go in when stage 7 pins down what a snapshot contains - a client compares its own digest against the authoritative one and reports the drift when it starts and then only now and then, rather than every step; the overlay says how long it has been out of step and at which tick - refusing to compare at all when the two builds disagree on the digest layout EU07_NETWORK_VERSION is now 4.
