Bridge ecrecover checks result ≠ address(0)

Chainlink CCIP's assessment for RD-F-151 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

[★ CRITICAL] GREEN - PASS. MultiOCR3Base.sol: oracle set assignment rejects address(0) with OracleCannotBeZeroAddress(). In _verifySignatures, ecrecover result checked against signer role map - zero-address cannot hold Role.Signer. RMNRemote.sol verify(): 'if (signerAddress == address(0)) revert InvalidSignature()'. Both DON OCR path and RMN verification path guard against zero-address ecrecover return.
