★ Reinitializable implementation (no _disableInitializers)
Sky Lending (formerly MakerDAO)'s assessment for RD-F-143 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
USDS.sol constructor calls _disableInitializers() — confirmed verbatim via WebFetch of GitHub source: 'constructor() { _disableInitializers(); // Avoid initializing in the context of the implementation }'. Core MCD contracts (Vat, Pot, Jug) are not proxy-based. sUSDS and SKY follow same OZ pattern per ChainSecurity/Cantina 2024 audits.

Methodology #
Determine whether the implementation contract does not call `_disableInitializers()` in its constructor, leaving re-initialization possible.
