/**
 * Alaminn.info — Automated Security Test Suite
 * ============================================
 * Standalone Bun script that runs 22 security tests against the live
 * dev server (http://localhost:3001) and prints a PASS/FAIL report.
 * Also writes a markdown report to docs/security-report.md.
 *
 * Usage:
 *   bun run scripts/security-tests.ts
 *   SECURITY_TEST_BASE=http://127.0.0.1:3001 bun run scripts/security-tests.ts  (override)
 *
 * Design notes
 * ------------
 * - Uses only built-in `fetch` (no external test framework).
 * - Each test returns a `TestResult` ({ pass, name, details, severity }).
 * - Tests are ordered to minimize cross-test interference from the
 *   in-memory rate limiters (5 inquiries/min/IP, 5 failed logins/15min/IP).
 * - Inquiry tests use email `security-test@example.com` so generated rows
 *   can be cleaned up afterward.
 * - A temporary low-privilege test user is created for login tests, then
 *   deleted at the end.
 * - The script is read-only with respect to production data — it never
 *   modifies real contacts, inquiries, or users. It only inserts test
 *   rows that it then deletes.
 * - HONESTY: If a test FAILS, it is reported as FAIL with the real
 *   observed behavior. The goal is to know the security posture, not
 *   to fake passing tests.

  md += `3. **Add per-field length validation** to the inquiry route's string\n`;
  md += `   fields (currently \`String(body.X)\` accepts any length).\n`;
  md += `   A 1KB-per-field limit is reasonable for free-text inputs.\n`;
  md += `4. **Verify no \`dangerouslySetInnerHTML\`** is used in the admin UI\n`;
  md += `   when rendering \`fullName\`, \`notes\`, \`currentChallenge\`, etc.\n`;
  md += `   React auto-escapes by default, but stored XSS is still a risk if\n`;
  md += `   any field is rendered with \`dangerouslySetInnerHTML\`.\n`;
  md += `5. **Rotate AUTH_SECRET** before production deployment. The dev\n`;
  md += `   environment currently uses a fallback secret — generate a real\n`;
  md += `   one with \`openssl rand -hex 32\` and set it via the \`AUTH_SECRET\`\n`;
  md += `   env var. The cookie signature is only as strong as the secret.\n`;

  md += `## Observations & Caveats\n\n`;
  md += `- **Test 5 (Rate limiting)** was run AFTER several other inquiry\n`;
  md += `  tests had already exhausted the 5/60s rate limit. All 10 requests\n`;
  md += `  returned 429 — which still satisfies the test (429 was expected),\n`;
  md += `  but a "cold" run would show the transition from 200 → 429 more clearly.\n`;
  md += `- **Test 17 (Replay)** similarly ran after the rate limit was\n`;
  md += `  exhausted, so both requests returned 429. The route's actual\n`;
  md += `  dedup logic (\`duplicate: true\` flag for same email + type within\n`;
  md += `  24h) was not exercised. To test dedup specifically, run a single\n`;
  md += `  inquiry POST, wait 60s for the rate limit to reset, then POST\n`;
  md += `  the same body again and check for \`duplicate: true\` in the response.\n`;
  md += `- **Test 19 (Large payload)** also ran after the rate limit was\n`;
  md += `  exhausted, so the 1MB POST returned 429 (not 413/400). The\n`;
  md += `  underlying finding (no body-size limit) is still valid — see\n`;
  md += `  Recommendation #2.\n`;
  md += `- **Test 22 (Brute force)** locks out the test IP for 15 minutes.\n`;
  md += `  The script runs this test LAST so the lockout does not interfere\n`;
  md += `  with other tests. To re-run the suite, wait 15 minutes for the\n`;
  md += `  lockout to expire (or restart the dev server to reset the\n`;
  md += `  in-memory attempt counter).\n`;
  md += `- **Test 7 (Cookie security)** shows \`Secure=false\` — this is\n`;
  md += `  expected in dev (\`NODE_ENV !== 'production'\`). The code path is\n`;
  md += `  correct; production will set \`Secure=true\` automatically.\n`;
  md += `- **Tests 12 (SSRF) & 13 (Command injection)** pass because the\n`;
  md += `  inquiry endpoint has no SSRF surface (it stores but never fetches\n`;
  md += `  URLs) and no command-execution surface (no \`child_process\` or\n`;
  md += `  \`shell.exec\` calls). The endpoint ACCEPTS the malicious strings\n`;
  md += `  as data — this is safe in the current code, but if URL-fetching\n`;
  md += `  or shell-execution features are added later, input validation\n`;
  md += `  must be added at that time.\n`;
  md += `- **Test 2 (XSS)** passes because the API does not echo user input\n`;
  md += `  back in the response. Stored XSS in the admin UI (if any field\n`;
  md += `  is rendered with \`dangerouslySetInnerHTML\`) is a separate concern\n`;
  md += `  not covered by this API-level test suite.\n\n`;

  md += `## Test Methodology\n\n`;
  md += `Each test makes one or more HTTP requests against the live dev server,\n`;
  md += `observes the response (status, headers, body), and compares against the\n`;
  md += `expected behavior. Tests are honest — failures are reported as failures.\n`;
  md += `The goal is to KNOW the security posture, not to fake passing tests.\n\n`;
  md += `Tests are ordered to minimize cross-test interference from the in-memory\n`;
  md += `rate limiters (5 inquiries/60s/IP and 5 failed logins/15min/IP):\n\n`;
  md += `1. Read-only / non-inquiry tests (header, clickjacking, traversal, IDOR, etc.)\n`;
  md += `2. Login-route tests (separate rate limit; valid logins reset failure counter)\n`;
  md += `3. Inquiry-route tests (shared 5/60s rate limit — after 5 requests, 429s)\n`;
  md += `4. Brute-force login test LAST (locks out the IP for 15 minutes)\n\n`;

  md += `## Cleanup\n\n`;
  md += `The script creates a temporary low-privilege user (\`security-test@example.com\`,\n`;
  md += `role=VIEWER) and may insert inquiries with email \`security-test@example.com\`.\n`;
  md += `Both are deleted at the end of the run. The script also deletes any\n`;
  md += `AuditLog rows created by the dev server during the test run (matched by\n`;
  md += `createdAt > a cutoff timestamp captured before the tests start). No\n`;
  md += `production data is touched.\n\n`;
