★ Default bytes32(0) acceptable as valid root

PancakeSwap's assessment for RD-F-154 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

[★ N/A-pattern] LayerZero V1 does NOT use Merkle root-based proof verification. No inbox contract accepting bytes32 roots. V1 proof model is oracle (block header hash) + relayer (Merkle branch proof of tx-in-block). Nomad bug class (acceptableRoot(bytes32) accepting 0) has no applicable analogue in V1 architecture.
