Verityv2.2.2

RWA oracles that bleed when they're wrong.

An autonomous oracle agent that reasons over conflicting evidence, whose on-chain reputation rises and falls with accuracy, and whose data you pay for per query via Casper x402. When the oracle is wrong, its score drops — visibly, on-chain.

Price scales with reputation: a higher score earns a higher price. Boolean settlement only — the consumer pays, reads the value, and learns nothing else about the agent.
