Circuit breaker on price deviation

Veda (BoringVault)'s assessment for RD-F-057 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

The AccountantWithRateProviders implements auto-pause as circuit breaker when new exchange rate exceeds allowedExchangeRateChangeUpper or falls below allowedExchangeRateChangeLower. No protocol-level circuit breaker on individual Chainlink feed staleness. The circuit breaker applies to the share-price oracle, not to underlying Chainlink feeds.
