_mockPriceFeedsAtTimelockExecution​

GovernorBravoProposal simulates execution after the timelock delay by warping the fork forward. On a static fork, external oracle contracts do not receive the Chainlink/API3/RedStone updates that would occur during that real elapsed time, so PRICE can reject otherwise valid proposal actions with stale-feed errors.

The proposal actions depend on PRICE during simulation because deploying the cache-backed oracle clones seeds/validates the OHM/USDS cache. Preserve the feed answers from the fork, but move their timestamps to the simulated timelock execution time so the simulation exercises the proposal logic instead of failing on fork-only clock drift. These mocks are cleared immediately after simulation and do not affect the calldata submitted to governance.

function _mockPriceFeedsAtTimelockExecution(Addresses addresses) internal;

addressesAddresses
