UUPS _authorizeUpgrade correctly permissioned

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

Evidence summary #

Protocol uses TransparentUpgradeableProxy (not UUPS). In the transparent proxy pattern, _authorizeUpgrade() does not exist; upgrade authority is held by the ProxyAdmin (TimelockController 0xc26016f1166bE7b6c5611AAB104122E0f6c2aCE2). UUPS-specific check is not applicable.
