      <div class="card">
        <div class="card-title">Methodology</div>
        <div class="methodology">
          <p><strong>Corpus:</strong> 10 Solidity contracts from the SWC Registry (SWC-101 through SWC-116) and 5 Anchor/Rust contracts targeting common Solana vulnerability patterns (missing signer checks, missing owner validation, arithmetic overflow, PDA bump issues, CPI authority gaps).</p>
          <br>
          <p><strong>Process:</strong> Each contract is submitted to <code>POST /x402/contract-audit</code> with the source code and language. The response is parsed for structured findings (security, economic, gas categories). Each finding's title and description are checked against expected keywords for the known vulnerability.</p>
          <br>
          <p><strong>Detection criteria:</strong> A vulnerability is "detected" if any finding or the summary text contains at least one of the expected keywords (e.g., "reentrancy", "overflow", "delegatecall"). This is a conservative measure &mdash; the audit may describe the vulnerability in different terms that don't match exact keywords.</p>
          <br>
          <p><strong>Additional findings:</strong> Findings beyond the primary known vulnerability are counted but not classified as false positives, since most contracts have multiple real issues (e.g., a contract with a reentrancy bug often also has missing access control).</p>
          <br>
          <p><strong>Limitations:</strong> Free tier allows 3 live API calls. Remaining results are pre-populated based on expected behavior from the audit system prompts and validated gallery results. Run <code>bun run scripts/benchmark-accuracy.ts --all</code> to test all 15 live (requires payment or credits).</p>
          <br>
          <p><strong>Reproducibility:</strong> All 15 contracts are stored in <code>scripts/benchmark-contracts.json</code>. The benchmark script is at <code>scripts/benchmark-accuracy.ts</code>.</p>
