WONDER CHAMBER / LOCKSTEP@1

Twins in lockstep.

One input log. Two isolated worlds.
The first changed bit leaves a red notch.

Starting two isolated replay workers…Engine

Fixed 120 Hz · FNV‑1a state checks · no sound · drag the desk to inspect the machining.

This browser demo replays the same input log in two local workers.

ROTOR / CHECKING--------

What is being compared?

The Node/V8 fixture stores the original arena input log and every post-tick state hash. Each laptop owns a separate module worker and replays that same log. The rotor below the screens uses only the owned deterministic math; its 3,600-tick state must match the committed golden hash.
