★ Default bytes32(0) acceptable as valid root

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

Evidence summary #

[★ CRITICAL] Cannot assess — MultipliBridger source not available. If custom bridge with Merkle-root validation: bytes32(0) acceptance is a catastrophic Nomad-class bug ($190M). If LayerZero OFT (no Merkle roots in OFT design): factor would be not_applicable. Source opacity prevents assessment.
