Fallback behavior on oracle failure

Evidence summary #

Fallback behavior on oracle failure | Core Bridge has no price oracle, so oracle failure is not applicable in the traditional sense. For guardian network: if quorum falls below 13/19, VAA production halts. No documented automated fallback — bridge freezes rather than degrading gracefully to a secondary trust source. For NTT: rate limits queue transfers rather than silently dropping them when limits exceeded. | Profile §7; Wormhole docs on VAA model; NTT rate limiting docs (wormhole.com/docs/p...

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