  "agent": "security",
  "verdict": "APPROVED",
  "summary": "Security gate passed. Header propagation sanitized against injection, no stack/internal leakage, log injection neutralized by JSON serialization, zero audit vulnerabilities with pino+zod.",
  "checks": {
    "dependencies": "PASS: npm audit -> 0 vulnerabilities; pino/zod justified in spec/tech.md",
    "header_injection": "PASS: incoming x-request-id accepted only under ^[A-Za-z0-9._-]{1,128}$; newline and 129-char payloads replaced by UUID (regression tests present)",
    "response_leakage": "PASS: 5xx path forces generic 'Internal Server Error'; body assertions confirm absence of thrown message and stack; 4xx exposes only safe messages/codes",
    "log_injection": "PASS: requestId is pre-sanitized; url/method serialized via pino JSON encoding which escapes control characters",
    "dangerous_patterns": "PASS: no eval / new Function / child_process in src"
  },
  "findings": [
    {
      "severity": "info",
      "note": "Fastify 4xx codes exposed in envelope (e.g. FST_ERR_CTP_INVALID_JSON_BODY) are public framework codes; no internal state disclosed."
    }
  ],
  "evidence": [
    "npm audit -> found 0 vulnerabilities",
    "grep eval|new Function over src -> none",
    "grep x-request-id non-test usages -> only constant + sanitized generator path",
    "5xx generic guard verified at build-app.ts lines 68/75",
    "test 'internal errors never leak message or stack to the client' passes"
