Fallback behavior on oracle failure

Aave v3's assessment for RD-F-051 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

AaveOracle has a FallbackOracle mechanism contractually (setFallbackOracle()) but it is non-functional in production — configured to zero address or equivalent per T-10 assessment. If primary Chainlink feed reverts or returns stale data, no automatic fallback activates. Pool-dependent functions revert.
