| RUN-001 | Uncaught JavaScript error | critical | 60 | An unhandled JS exception was thrown while the page ran in a real browser, likely breaking behaviour. |
| RUN-002 | Console error | medium | 20 | The page logged an error to the browser console at runtime. |
| RUN-003 | Content-Security-Policy blocked a resource | high | 36 | A script, style, or connection was blocked by the CSP at runtime, so a feature failed to load or work. |
| RUN-004 | Runtime resource failed to load | medium | 25 | A subresource request failed or returned an error while the page was running (broken script/style/image/API). |
| RUN-005 | Key content failed to render | high | 36 | A primary content area rendered empty in a real browser — the page loads over HTTP but is broken at runtime. |
| RUN-006 | Interactive element throws on use | high | 24 | Clicking a primary control raised a JavaScript error instead of doing something. |

| REL-001 | Server errors observed | critical | 60 | One or more requests returned a 5xx during the scan. |
| REL-002 | Inconsistent responses | high | 24 | Repeated identical requests returned different statuses or wildly different payloads (flakiness). |
| REL-003 | Soft-404 / missing not-found handling | medium | 5 | A clearly non-existent path returns 200 OK instead of a proper 404 page. |
| REL-004 | High response-time variance | low | 6 | Repeated requests show large latency swings, indicating instability under light load. |

|---|---|---|---|---|
| SEC-001 | No HTTPS enforcement | critical | 30 | Site is served over plain HTTP or does not redirect HTTP→HTTPS. |
| SEC-002 | Missing HSTS header | medium | 5 | Strict-Transport-Security header absent on HTTPS responses. |
| SEC-003 | Missing Content-Security-Policy | medium | 5 | No CSP header, increasing XSS blast radius. |
| SEC-004 | Missing X-Content-Type-Options | low | 2 | nosniff header absent; MIME-sniffing attacks possible. |
| SEC-005 | Clickjacking protection missing | medium | 5 | Neither X-Frame-Options nor frame-ancestors CSP directive present. |
| SEC-006 | Insecure cookie flags | high | 24 | Session/identifying cookies set without Secure and/or HttpOnly. |
| SEC-007 | Sensitive file exposed | critical | 60 | A sensitive file (.env, .git/config, backup) is publicly downloadable. Only probed with verified ownership. |
| SEC-008 | Dangerous CORS configuration | high | 12 | Access-Control-Allow-Origin: * combined with credentials, or reflective origin allow-listing. |

| SEC-014 | No SPF record | medium | 5 | The domain publishes no SPF DNS record, so anyone can spoof email 'from' this domain — a common phishing vector. (Signal, not a mail-server audit.) |
| SEC-015 | No or weak DMARC policy | medium | 5 | The domain has no DMARC record, or a permissive p=none policy, so spoofed mail isn't rejected. Strengthens brand trust and anti-phishing. |
| SEC-016 | TLS certificate expired or expiring soon | high | 30 | The site's TLS certificate has expired or expires within 14 days — visitors will (or soon will) see a full-page browser security warning. |
| SEC-017 | External script without Subresource Integrity | low | 6 | A cross-origin <script> is loaded without an integrity (SRI) hash, so a compromised CDN could silently serve malicious code (supply-chain risk). |

| UXA-007 | Duplicate element IDs | low | 4 | Duplicate id attributes break ARIA references and label associations (WCAG 4.1.1). |
| UXA-008 | Low text contrast | medium | 12 | Text fails the WCAG AA contrast ratio (4.5:1 normal, 3:1 large) against its background — hard to read for low-vision users (measured in a real browser — Deep Dive). |

| CODE-006 | No linter configuration | low | 6 | No linter/formatter config detected (eslint, ruff, rubocop, etc.) — style is unenforced (repo mode). |
| CODE-007 | Dependency with known vulnerabilities | high | 30 | A runtime (production) package in the connected repo's manifest is pinned to a version with published security advisories (CVE-class). Upgrade to a patched release (repo mode). |
| CODE-008 | Dev dependency with known vulnerabilities | low | 10 | A dev-only package (build/test tooling, not shipped to production) is pinned to a version with published security advisories. Lower risk since it isn't served to users, but worth upgrading (repo mode). |

| GEN-001 | Pre-checked opt-in box | medium | 15 | A consent/marketing checkbox is pre-ticked by default, opting the user in without an affirmative choice — a recognised dark pattern (and unlawful consent under GDPR/ePrivacy). |
| GEN-002 | Urgency/scarcity messaging | low | 6 | High-pressure urgency or scarcity messaging is present (e.g. 'only 2 left', 'offer ends soon'). A neutral signal — legitimate when it reflects real inventory/deadlines; worth confirming it isn't manufactured. |
| GEN-003 | Fake countdown timer | medium | 10 | A countdown timer resets to the same value on reload, so the 'deadline' is not real — a deceptive urgency pattern (measured in a real browser — Deep Dive). |
| GEN-004 | Confirmshaming decline text | low | 6 | An opt-out is worded to shame or guilt the user for declining (e.g. 'No thanks, I like paying full price') — a manipulative choice-architecture pattern. |
| GEN-005 | No verifiable business identity | low | 4 | The site solicits payment or subscriptions but exposes no way to identify or contact the business behind it (no address, company registration, or contact method) — a common trait of throwaway/scam sites. |
| GEN-006 | Undisclosed AI interaction | low | 4 | An AI assistant/chatbot feature is present with no statement that users are interacting with AI or that content is AI-generated. Certifies transparency, not 'human-made' — the defensible AI-authenticity signal. |

| AIQ-003 | Inaccurate answer (hallucination) | high | 36 | The product gave a materially incorrect answer to a question whose correct answer is established in the provided ground truth. |
| AIQ-004 | Confident fabrication on an unanswerable question | high | 24 | Asked something it cannot know, the product invented a confident answer instead of declining or saying it doesn't know. |
| AIQ-005 | Inconsistent answers across repeated runs | medium | 20 | The same question asked multiple times produced materially different answers, indicating unreliable behaviour. |
| AIQ-006 | No AI disclosure when asked | medium | 10 | Asked directly, the product did not disclose that the user is interacting with AI — an emerging transparency-regulation requirement. |
| AIQ-007 | Produced unsafe or disallowed content | high | 36 | On a safety probe, the product generated harmful, disallowed, or clearly out-of-policy content it should have refused. |
