| Reactor | UltimateSingularityProtocol — the core yield contract. Deposits buy Radiation, Radiation converts to Reactor Nodes. |
| Reactor Nodes | The miner unit. Emits Radiation continuously; RADIATION_TO_CONV_1NODE = 1,080,000 radiation per node. |
| Radiation | The accruing yield balance. Sells back to the curve via extractRadiation() (10% node burn, 2× lifetime cap). |

| MASS | Live DarkMatterNFT mass. Gates VIP membership (≥32) and sets raffle weight. Founder Pass = flat 100-mass seat. |
| DUST | Non-transferable activity score (StardustWheel). Earned on deposits/check-ins/awards; spent on wheel spins. No monetary rights. |
