UUPS _authorizeUpgrade correctly permissioned

EigenLayer'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 #

EigenLayer uses Transparent Upgradeable Proxy (TUP) pattern, not UUPS. Under TUP, upgrades are controlled by the Proxy Admin contract (0x8b9566AdA63B64d1E1dcF1418b43fd1433b72444), not via _authorizeUpgrade(). This factor is N/A for TUP architecture. Upgrade admin posture belongs to Cat 2.

Methodology #

Determine whether the UUPS implementation defines `_authorizeUpgrade(address)` restricted to owner/admin/timelock (not open to arbitrary callers).
