Audit scope mismatch

Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-001 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Seven firms, 20+ engagements cover all major contracts across upgrade cycles. Private 'pegasus' repo blocks independent commit-SHA-to-bytecode verification. December 2024 DaoCollateral/SwapperEngine upgrade and post-May-2025 exploit remediation represent post-audit-coverage windows that cannot be independently verified. Subsequent audits (Cantina Phase 1+2 Oct 2024, Halborn Nov 2024, Spearbit Jan 2025, Sherlock #832 March 2025 $209.5K pool) were staged to cover each upgrade cycle, but private repo prevents confirming audit scope commit matches deployed bytecode.
