Bridge binds message to srcChainId

Fluid'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 #

CCIP OffRamp.sol binds messages to source chain via merkle root structure (each source chain has a separate committed root). The CommitStore/OffRamp tracks per-source-chain state. The CCIP architecture explicitly separates per-chain message commitment to prevent cross-chain replay. Green for CCIP path.

Methodology #

Determine whether the bridge message struct includes `srcChainId` and the verifier enforces per-chain separation.
