Bridge binds message to srcChainId

Lista DAO's assessment for RD-F-152 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

LayerZero V2 EndpointV2 enforces origin chain ID (Origin.srcEid) in all message delivery. Each packet includes endpoint IDs (srcEid, dstEid). OFT validates peer addresses per chain via peers[dstEid]. Chain binding enforced at the protocol layer. setPeer() and peers() functions confirmed in ListaOFTAdapter ABI.
