Findings separate the observed evidence from the analyst outcome.

Severity	Dimension	Finding	Outcome	Evidence	Sources
critical	bridge wrapper	DVN threshold configuration is a critical dependency	A bridge or watcher can release unbacked assets.	OFT assets depend on configured verification paths and cross-chain invariant checks.	LayerZero docs

Inbound and outbound trust assumptions touching this protocol.

Severity	Direction	Edge type	Dependency path	Analyst label
critical	inbound	bridged by	rsETH -> LayerZero	rsETH cross-chain paths can depend on LayerZero-style verification
critical	outbound	verified by	LayerZero -> Ethereum	LayerZero-linked assets need source and destination chain invariant checks
low	outbound	settles on	LayerZero -> Ethereum	LayerZero deployment inherits Ethereum settlement risk

Public operational signals and review cadence.

planned	Admin and guardian changes	Owner, guardian, Safe signer, threshold, and emergency role changes.	15 min after ingestion
planned	Oracle freshness	Heartbeat breaches, stale rounds, and large reference-market deviations.	5 min after ingestion
manual	Liquidity and cap shock	Supply cap utilization, borrow cap utilization, TVL drops, and liquidity depth changes.	Daily analyst review

Highest-severity paths that could transmit risk into or out of this protocol.
