Fallback behavior on oracle failure

mETH Protocol'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 #

On Oracle sanity check failure: protocol auto-pauses (no secondary oracle fallback). On quorum not reached: record not forwarded to Oracle; rate freezes at last valid record. Pending updates can be accepted/rejected by ORACLE_PENDING_UPDATE_RESOLVER_ROLE. No secondary oracle source configured. Pause is protective but halts all staking/unstaking.

Methodology #

Identify the declared fallback behavior (pause, secondary source, last-known-price, revert) when the primary oracle reverts or reports a stale value.
