Mechanism: CustomAggregatorV3CompatibleFeed: a Chainlink-shaped feed with a feed admin role. setRoundData checks only minAnswer <= value <= maxAnswer; setRoundDataSafe additionally requires deviation(last, value) <= maxAnswerDeviation (percent at 10^decimals scale) and, in the 2026-06 implementations, more than one hour since the last post.
