Storage-layout collision risk across upgrades

Multipli'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 #

MultipliVault uses ERC-7201 namespaced storage pattern (confirmed from API analysis: 'ERC-7201 storage pattern compliance'). AuthUpgradeable uses dedicated storage slot 0xdd3fd67a... This mitigates storage collision across upgrades. No upgrade history to analyze for actual collisions.
