Storage-layout collision risk across upgrades

Lido'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 #

Lido uses Aragon AppProxyUpgradeable pattern, pre-dating OZ upgrades plugin. No OZ upgrades plugin collision confirmation found. However, Certora formal verification (V3) would likely detect storage collisions. Aragon's fixed storage layout reduces risk for the proxy layer.
