Evidence summary #
No circuit breaker on price deviation is documented or visible in JustLend's oracle contracts. SimplePriceOracle.sol stores prices directly without any deviation check against a secondary reference. PriceOracleProxy.sol does not implement a deviation-based halt. The poster submits prices without on-chain validation against an anchor or secondary source.
