★ Oracle source = spot DEX pool (no TWAP)

Cap (cUSD / stcUSD)'s assessment for RD-F-053 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

[★ CRITICAL] GREEN — No spot DEX pool oracle. Cap uses Chainlink push feeds (latestRoundData via adapter), RedStone push feed (NAV-based, 0.05% deviation), and Morpho/Chainlink adapter for stcUSD (ERC4626 conversion rate + Chainlink feeds, no TWAP). Primary/backup fallback implemented in PriceOracle.sol. No Uniswap TWAP or spot pool in price path.
