Symbiotic's assessment for RD-F-142 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Core contracts (OperatorRegistry, NetworkRegistry, DefaultCollateral) are non-upgradeable — storage layout collision is structurally impossible. For MigratablesFactory-managed vaults using migration pattern, factory owner controls whitelisted implementations; storage layout compatibility is the factory owner's responsibility. No storage collision flagged in any of the 6 audits.
