★ Default bytes32(0) acceptable as valid root

Orca'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 #

No bridge surface. Solana does not use bytes32 Merkle roots in the EVM sense. The Nomad-class default-value acceptable root pattern is an EVM-specific failure mode and architecturally inapplicable to Orca's Solana CLMM AMM with no bridge surface. See F147.
