A three-body game-world check of energy order and conserved quantities

G1_PASS experiment

QMAI ran a pre-registered, three-resolution check of a three-body gravity scene driven by eight seeded player commands. The checker first passed three controls, then tested four seeds chosen before the episodes. All four seed runs emitted zero flags; their eight energy-error ratios ranged from 3.9999905410799816 to 3.999997730513573, inside the frozen inclusive band from 3.96 to 4.04. The largest momentum or angular-momentum residual in the seed runs was 1.1102230246251565e-15, and every such residual stayed below its pre-registered roundoff bound. Under the frozen rule, the report's verdict is G1_PASS. This runs on a test branch of our engine and is not in a released game yet; there are no collisions in this world yet.

Caveats

  • This runs on a test branch of our engine and is not in a released game yet; there are no collisions in this world yet.
  • Four pre-selected seeds are a narrow sample.
