UUPS _authorizeUpgrade correctly permissioned

Wormhole'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 #

Wormhole uses EIP-1967 Transparent Proxy, not UUPS. Upgrade authority flows through governance VAAs (not `_authorizeUpgrade`). The transparent proxy pattern delegates upgrade authority to the ProxyAdmin / Guardian governance mechanism, not to the implementation contract's `_authorizeUpgrade` function. UUPS-specific factor does not apply.

Methodology #
