PancakeSwap'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 #

Predictions: oracle failure → round cancelled, users refunded (no fund loss, UX disruption). Perpetuals (ApolloX): triple-oracle provides implicit fallback — documented that it 'dodges unexpected price behaviours.' AMM: no oracle, no fallback needed. Other Chainlink-consuming functions (AVAX/USD 86400s, COMP/USD 86400s): no documented fallback.
