Bridge tracks nonce-consumed mapping

Veda (BoringVault)'s assessment for RD-F-153 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Nonce/replay protection is handled by the LayerZero v2 EndpointV2 at 0x1a44076050125825900e736c501f859c50fe728c. The LayerZeroTeller does not implement its own nonce-consumed mapping — delegation to LZ v2 endpoint is the standard pattern. LayerZero v2 endpoint-level nonce protection is widely deployed and audited, but cannot independently verify endpoint nonce logic.
