      "rationale": "Correctly identifies the vulnerable `/api/search/visit` endpoint in `src/endpoints/search.js` and the server-side fetch behavior. The submission is well aligned to the advisory’s SSRF scope, with only a minor mismatch in describing the exact validation implementation."

      "score": 26,
      "rationale": "Shows a coherent flow from attacker-controlled `url` input through hostname validation to the outbound fetch and returned response, and notes the explicit-port restriction to default ports. Some reasoning goes beyond what is directly grounded in the cited code, especially around DNS rebinding and extra address forms."

      "score": 15,
      "rationale": "The core impact—SSRF to localhost/internal services on ports 80/443—is technically credible and proportional. However, claims about cloud metadata access, exfiltration, and pivoting are more speculative than the code evidence presented."

      "key": "evidence-quality",
      "score": 6,
      "rationale": "Cites the correct file and some concrete implementation details, but the evidence is weaker than ideal: it leans on inferred `ip-regex` behavior and peripheral routing references instead of directly quoting the handler’s `url` intake, port rejection, and fetch/response path."

      "key": "overclaim-control",
      "score": 5,
      "rationale": "It avoids major disallowed claims such as RCE, SQLi, arbitrary-port SSRF, or unauthenticated exploitation. Still, it overreaches somewhat with DNS rebinding, IPv6-mapped forms, metadata-service access, and pivoting language without direct support from the supplied code evidence."

  "misses": [
    "Does not cleanly anchor the report to the advisory’s specific dotted-quad hostname validation check; it substitutes a broader `ip-regex` characterization.",
