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

Evidence summary #

Bridge binds message to srcChainId | YES — VAA body structure includes `emitter_chain` (u16) identifying the originating chain. This is part of the double-hashed body that all guardians sign. Per-chain separation enforced by the VAA's unique index `(emitter_chain, emitter_address, sequence)`. | VAA docs: wormhole.com/docs/protocol/infrastructure/vaas/ — emitter_chain u16 field | GREEN
