Fallback behavior on oracle failure

Jito'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 #

Solana core: no oracle to fail (intrinsic). Arbitrum StakePoolRate: staleness revert present (allowedRateStaleness immutable threshold) but no secondary oracle fallback. If updater service offline, getRate() reverts — EVM consumers halt JitoSOL borrowing. No documented fallback oracle or secondary source for the cross-chain rate relay.

Methodology #

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