Evidence summary #

UUPS upgrades performed multiple times across major contracts (weETH: 4 upgrades, EtherFiAdmin: 5 upgrades, EtherFiNodesManager: multiple). OZ upgrades plugin presumably used internally but no public storage layout collision report found. Cannot confirm absence of collision risk externally.
