★ Oracle source = spot DEX pool (no TWAP)

Lombard Finance's assessment for RD-F-053 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

[★ CRITICAL — GREEN] No DEX spot price oracle found in any Lombard source file. LBTC minting/burning is Consortium-authorized, not price-oracle gated. BTC/USD from Chainlink is a push oracle with no DEX component. StakedLBTCOracle derives LBTC/BTC exchange rate from Consortium-signed ratio, not DEX. No slot0(), getReserves(), or equivalent DEX price read found in contracts/LBTC/, contracts/PoR/, or contracts/bridge/ directories. Source inspection of all oracle-related contract directories confirms absence of any spot DEX oracle dependency.
