UUPS _authorizeUpgrade correctly permissioned

Balancer (v2 + v3)'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 #

Balancer v2 pool contracts are immutable deployments from factories — no UUPS proxy pattern. v3 Vault uses delegatecall to hardcoded VaultExtension/VaultAdmin addresses (set in constructor), not UUPS upgradeable proxy. No UUPS _authorizeUpgrade pattern in either version. N/A is appropriate — this factor measures a specific proxy pattern that Balancer does not use.

Sources #

Methodology #

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