★ Post-audit code changes without re-audit
Yearn Finance's assessment for RD-F-139 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
V3 core (VaultV3.vy): last external audits May-June 2024 (ChainSecurity, Statemind, yAcademy). ChainSecurity fixes deployed Oct 30, 2024; v3.0.4 final deploy Nov 1, 2024 — core vault is stable post-audit with the audit-fix commit deployed. Periphery/strategy ecosystem continues to evolve per governance forum retroactive review proposal (2026-04). Gov forum explicitly acknowledges ongoing unaudited strategy codebase changes. No comprehensive re-audit of strategy periphery since mid-2024. Yellow: core vault unchanged post-audit; strategy/periphery drift is documented and ongoing.
