Fallback behavior on oracle failure

Veda (BoringVault)'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 #

No protocol-level fallback oracle on Chainlink failure. If Accountant rate update fails bounds check or delay check, contract auto-pauses — halting deposits and withdrawals. No secondary oracle source is configured. Pause is the only circuit breaker.
