Storage-layout collision risk across upgrades

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

Evidence summary #

Bridge2 uses AdminUpgradeabilityProxy (OZ pattern). No OZ upgrades plugin storage-layout check artifact publicly available. Foundation can upgrade implementation unilaterally — if a storage-layout change is introduced, state corruption risk exists. Structural to the upgrade model; not confirmed as exploited.
