UUPS _authorizeUpgrade correctly permissioned

Maple Finance's assessment for RD-F-021 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

MapleCCIPReceiver (UUPS) uses proxiableUUID() and upgradeToAndCall() with DEFAULT_ADMIN_ROLE gating _authorizeUpgrade. Core V2 contracts (NonTransparentProxy/MapleProxied) use admin-only setImplementation() — equivalent protection.

Methodology #
