## Security

### Security Headers (B — 70/100)

*6 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured
- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured
- **[WARNING]** Referrer-Policy has a weak value
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[PASS]** Content-Security-Policy is present
- **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[PASS]** X-Powered-By header is not present
- **[PASS]** Server header is present without version info
- **[PASS]** Domain is in the Chrome HSTS preload list (status: preloaded)

### Content Security Policy (A+ — 100/100)

*9 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[PASS]** default-src directive is set
- **[PASS]** No 'unsafe-inline' in script source
- **[PASS]** No 'unsafe-eval' in script source
- **[PASS]** No wildcard in script source
- **[PASS]** object-src falls back to default-src
- **[PASS]** base-uri is properly restricted
- **[PASS]** frame-ancestors directive is set
- **[PASS]** form-action directive is set
- **[PASS]** upgrade-insecure-requests is enabled

### TLS & Certificates (A+ — 100/100)

*TLS 1.3, 7 checks passed*

- **[PASS]** TLS 1.3 is used
- **[PASS]** Strong cipher suite is used
- **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance.
- **[INFO]** OCSP stapling not enabled — Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server.
- **[PASS]** Certificate is valid (expires in 84 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 2 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 95/100)

*3 cookies analyzed, 8 checks passed*

- **[PASS]** Cookie '_gh_sess' has the Secure flag
- **[PASS]** Cookie '_gh_sess' has the HttpOnly flag
- **[PASS]** Cookie '_gh_sess' has SameSite=Lax
- **[PASS]** Cookie '_octo' has the Secure flag
- **[WARNING]** Cookie '_octo' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft.
- **[PASS]** Cookie '_octo' has SameSite=Lax
- **[PASS]** Cookie 'logged_in' has the Secure flag
- **[PASS]** Cookie 'logged_in' has the HttpOnly flag
- **[PASS]** Cookie 'logged_in' has SameSite=Lax

### Cookie Hygiene (A+ — 100/100)

*All 3 cookie(s) pass hygiene checks*

- **[PASS]** All 3 cookie(s) pass hygiene checks

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

- **[INFO]** No WAF detected — Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva.

### security.txt (A+ — 100/100)

*Vulnerability disclosure policy*

- **[PASS]** security.txt found

### Cross-Origin Tab Safety (C — 75/100)

*1 of 11 new-tab link(s) missing rel=noopener*

- **[WARNING]** 1 link(s) open in a new tab without rel=noopener — Without rel="noopener", the destination tab can navigate the original tab via window.opener -- a reverse-tabnabbing phishing primitive. Modern browsers default to noopener since Chrome 88 / Firefox 79 / Safari 12.1, but explicit rel="noopener noreferrer" remains the documented best practice for older browsers, in-app webviews, and security scanners.

### CSP Inline-Style Readiness (D — 60/100)

*115 inline style attribute(s) detected*

- **[WARNING]** 115 inline style attribute(s) detected — Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 115 inline style(s) is high. Affected element types include: body, div, span, svg, input. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win.

### Trusted Types (XSS Sink Hardening) (B — 95/100)

*Trusted Types not enabled*

- **[INFO]** Trusted Types not enabled — Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode.

### Bot Challenge Detection (A+ — 100/100)

*Scan reached real page content (no bot-protection interstitial)*

- **[PASS]** No bot-protection interstitial detected -- the rest of the report reflects the real page

### Soft-404 Detection (A+ — 100/100)

*No soft-404 patterns detected in page title or headings*

- **[PASS]** No soft-404 patterns detected in page title or headings

### Empty Page Detection (A+ — 100/100)

*Page has substantive body text and no placeholder / template-leak signals*

- **[PASS]** Page has substantive body text and no placeholder / template-leak signals

### Geo-Restriction Detection (A+ — 100/100)

*No geo-restriction signals detected -- scan reached the page from an allowed region*

- **[PASS]** No geo-restriction detected

### Maintenance Mode Detection (A+ — 100/100)

*No maintenance-mode signals detected -- scan reached a normal page*

- **[PASS]** No maintenance-mode signals detected

### Subresource Integrity Adoption (F — 30/100)

*0% SRI adoption (0/80 third-party resources)*

- **[WARNING]** SRI adoption: 0/80 third-party resources protected (0%) — Of 80 third-party `<script>` / `<link rel=stylesheet>` resources, 0 (0%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource.

Missing SRI on (first 5 examples):
  - https://github.githubassets.com/assets/light-2ff56e1b36116ee2.css
  - https://github.githubassets.com/assets/light_high_contrast-f7f95d7633592089.css
  - https://github.githubassets.com/assets/dark-2d1fe43dbc9adf1f.css
  - https://github.githubassets.com/assets/dark_high_contrast-d530ee188d165539.css
  - https://github.githubassets.com/assets/primer-primitives-7f694b60439d06c0.css

Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.

### CORS Depth (A+ — 100/100)

*No CORS response headers -- the resource is same-origin-only by browser default*

- **[PASS]** No CORS response headers -- the resource is same-origin-only by browser default

### Permissions-Policy Granularity (C — 60/100)

*No Permissions-Policy header set -- powerful features (camera / microphone / geolocation / payment / USB) default to allow-on-same-origin*

- **[WARNING]** Permissions-Policy header not set -- features default to allow-on-same-origin — Without a `Permissions-Policy` (or legacy `Feature-Policy`) header, every powerful browser feature defaults to its spec default policy (typically `self`). A third-party iframe injected via XSS or a misconfigured embed can still request access to the user's camera, microphone, geolocation, payment APIs, USB devices, etc. Explicitly deny features the page doesn't need:

```
Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=(), accelerometer=(), gyroscope=()
```

Features the page legitimately uses can stay enabled with `feature=(self)`.

### Referrer-Policy Strictness (D — 50/100)

*Referrer-Policy is `origin-when-cross-origin` (leaky -- origin sent cross-origin even on protocol downgrade)*

- **[WARNING]** Referrer-Policy: `origin-when-cross-origin` -- leaky -- origin sent cross-origin even on protocol downgrade — Same-origin requests get full URL; cross-origin gets only origin. Similar shape to the modern default BUT does NOT suppress Referer on HTTPS-to-HTTP downgrade -- the origin leaks even when the protocol is downgrading to HTTP. Switch to `strict-origin-when-cross-origin` for the same UX with no downgrade leak.

### Source Map Exposure (A+ — 100/100)

*Source-map probe didn't run on this scan*

- **[PASS]** Source-map probe didn't run on this scan

### HTML Version Disclosure (A+ — 100/100)

*No software-version disclosures in HTML*

- **[PASS]** No software-version disclosures in HTML

### Open Redirect Surface (A+ — 100/100)

*No redirect-shaped query parameters in DOM links*

- **[PASS]** No redirect-shaped query parameters in DOM links

### Auth Security (A+ — 100/100)

*Page is not a login form -- auth-security checks are N/A*

- **[PASS]** Page does not appear to be a login form

### Subdomain Inventory Exposure (A+ — 100/100)

*No risky subdomain names in certificate SANs*

- **[PASS]** No risky subdomain names in certificate SANs

### JS Library Vulnerabilities (A+ — 100/100)

*No known vulnerabilities*

- **[PASS]** No known JavaScript library vulnerabilities detected

### Information Leakage (A+ — 100/100)

*No exposures*

- **[PASS]** security.txt is present — good practice
- **[PASS]** No sensitive files exposed

### Email Security (B — 72/100)

*DMARC: quarantine, SPF: ~all, DKIM*

- **[PASS]** DMARC policy is quarantine — good protection
- **[INFO]** SPF ends in ~all (soft fail) — Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify).
- **[PASS]** DKIM configured (selectors: k2, smtpapi, k1, google, selector1, s2, s1)
- **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.
- **[INFO]** TLS-RPT not configured — TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.<domain>.
- **[INFO]** BIMI not configured — BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.

### API Surface (A+ — 100/100)

*No API specs or GraphQL introspection found (probed 11 candidate path(s))*

- **[PASS]** No API specs or GraphQL introspection found (probed 11 path(s))

### Permissions-Policy (D — 40/100)

*No header set*

- **[WARNING]** No Permissions-Policy header — Consider adding a Permissions-Policy header to restrict browser feature access from embedded content.

### CORS Configuration (B — 80/100)

*No CORS headers*

- **[PASS]** No CORS headers present — secure default

## Performance

### Page Weight Budget (F — 0/100)

*4.4 MB transferred, 147 requests*

- **[CRITICAL]** Page weighs 13.4 MB (4.4 MB transferred)
- **[WARNING]** JavaScript is 1.7 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[WARNING]** Images are 1.2 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[INFO]** CSS is 279 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size.
- **[INFO]** Fonts are 251 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[WARNING]** 147 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 0.92 g CO2 per page load

### Third-Party Impact (D — 50/100)

*97% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 97% of page weight (4.3 MiB of 4.4 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (C — 65/100)

*18 images, 0 KB saveable*

- **[WARNING]** https://images.ctfassets.net/8aevphvgewt8/g1XhuDG7... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://images.ctfassets.net/8aevphvgewt8/6Qr8Snm4... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (F — 20/100)

*19430ms total JS execution*

- **[WARNING]** https://github.githubassets.com/assets/chunk-39118...: 8293ms CPU time
- **[WARNING]** https://github.com/: 2941ms CPU time
- **[WARNING]** https://github.githubassets.com/assets/react-lib-1...: 2790ms CPU time
- **[WARNING]** https://github.githubassets.com/assets/46752-7bd89...: 1201ms CPU time
- **[WARNING]** Unattributable: 1121ms CPU time
- **[WARNING]** Third-party scripts: 16489ms (85% of total)

### Font Loading (A+ — 100/100)

*2 fonts (251 KB)*

- **[INFO]** 2 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (F — 20/100)

*94 scripts, 788 KB unused*

- **[WARNING]** https://github.githubassets.com/assets/landing-pag...: 409 KB unused (93%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/primer-reac...: 67 KB unused (55%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/react-lib-1...: 51 KB unused (59%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/48761-e0d70...: 48 KB unused (42%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/react-core-...: 46 KB unused (70%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 788 KB

### Resource Caching (A+ — 100/100)

*All resources properly cached*

- **[PASS]** No caching issues found

### Critical Rendering Path (A+ — 100/100)

*No render-blocking resources*

- **[PASS]** No render-blocking resources detected

### Resource Hints (B — 75/100)

*8 hints, 0 missing preconnects*

- **[WARNING]** 1 font preload(s) missing `crossorigin` -- font will be downloaded twice — Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: https://github.githubassets.com/assets/MonaSansVF-wdth-wght-opsz-902d64c7ad02.woff2. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
- **[INFO]** 2 dns-prefetch redundant with preconnect on same origin — preconnect already does the DNS lookup; adding dns-prefetch to the same origin is at best a no-op. Sample: https://github.githubassets.com, https://avatars.githubusercontent.com. Remove the redundant dns-prefetch entries.
- **[INFO]** 2 URL(s) appear in multiple hints — The same href shouldn't appear in multiple hint rels -- one wins, the others are wasted markup and may confuse cache behavior. Sample: https://github.githubassets.com (dns-prefetch+preconnect), https://avatars.githubusercontent.com (dns-prefetch+preconnect).
- **[PASS]** Page uses 8 resource hint(s)

### HTTP/3 (QUIC) (B — 75/100)

*HTTP/3 not advertised*

- **[INFO]** HTTP/3 (QUIC) is not advertised — HTTP/3 isn't advertised via Alt-Svc and the worker didn't negotiate h3. HTTP/3 reduces handshake latency (1-RTT instead of 2-3 RTTs) and is more resilient on lossy connections. Most modern CDNs (Cloudflare, Fastly, AWS CloudFront, Google Cloud CDN) support HTTP/3 with a single config switch -- consider enabling for mobile-heavy workloads.

### Compression Algorithm (C — 70/100)

*Main response served uncompressed*

- **[INFO]** Main HTML response has no Content-Encoding (uncompressed) — The main HTML document is served without compression. The Text Compression section above lists the broader picture; for the main response specifically, even gzip would shave ~70-80% off most text payloads.

### LCP Image Preload (A+ — 100/100)

*LCP preload audit not available*

- **[PASS]** LCP image preload audit not available for this scan

### Main HTML Cache-Control (A+ — 100/100)

*Main HTML max-age=0 (≤ 5min) is appropriate*

- **[PASS]** Main HTML max-age=0 (≤ 5min) is appropriate

### Server-Timing Observability (B — 85/100)

*No Server-Timing header found*

- **[INFO]** No Server-Timing header found — Server-Timing exposes backend timing breakdowns to browser DevTools (e.g., `db: 45ms; render: 120ms; cache: 2ms`). Useful for diagnosing slow pages without backend log access. Most modern frameworks (Next.js, Cloudflare Workers, Fastly) emit it automatically; absence on a managed platform usually means telemetry headers are stripped at the edge.

### Server Response Intelligence (A+ — 100/100)

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: X-PJAX, X-PJAX-Container, Turbo-Visit, Turbo-Frame, X-Requested-With, Accept-Lan... — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[PASS]** `ETag` present -- conditional GET supported

### Page Weight Inventory (F — 30/100)

*147 resources · 4.4 MB · 788 KB savings available*

- **[WARNING]** Page weight 4.4 MB exceeds 1 MB target by 3.4 MB
- **[INFO]** ~788 KB of savings available
- **[WARNING]** 145 third-party resources (97% of weight)
- **[INFO]** 5 resources over 200KB

### Render-Blocking Resources (A+ — 100/100)

*No render-blocking resources detected*

- **[PASS]** No render-blocking resources detected in <head>

### Third-Party Resources (A+ — 100/100)

*No third-party resources detected*


### JavaScript Blocking (B — 70/100)

*2 JS blocking issue(s) detected*

- **[WARNING]** 7 render-blocking <script src> tag(s) without async/defer — Each `<script src=...>` without `async`, `defer`, or `type="module"` blocks HTML parsing while the browser fetches and executes it. The block lasts the entire round-trip + execution time -- on slow networks this translates directly into LCP delay. Add `defer` (executes after parse, in source order) for scripts that interact with the DOM, or `async` (executes whenever ready) for analytics / independent scripts. Module scripts (`type="module"`) are deferred by default.
- **[WARNING]** Total JS execution time is 19.4 s -- over the 3.5s budget — Total JavaScript execution (parse + compile + run) across all scripts exceeds 3.5 seconds. On low-end devices that becomes 7-15+ seconds and shows up directly in TBT and INP. Reduce by: tree-shaking unused dependencies, code-splitting (dynamic `import()`), removing or deferring third-party tracking, and replacing heavy frameworks where they're not needed.

### CSS Performance Depth (A — 88/100)

*1 CSS depth issue(s) detected*

- **[WARNING]** 20 render-blocking stylesheet(s) -- recommended: <=3 — Each `<link rel="stylesheet">` without a non-blocking `media` attribute holds up the first paint. Browsers download all of them before painting any content. Consolidate into 1-2 critical-path stylesheets; defer non-critical CSS via `<link rel="stylesheet" media="print" onload="this.media='all'">` or via the loadCSS pattern; inline above-the-fold CSS in `<style>` to short-circuit the request entirely.

## Content Quality

### Links (A — 90/100)

*200 links checked, 198 healthy, 2 broken*

- **[WARNING]** 198 of 200 links are healthy
- **[WARNING]** Broken link: https://github.githubassets.com — Found in <link href>. Returns HTTP 404.
- **[WARNING]** Broken link: https://github.githubassets.com/ — Found in <link href>. Returns HTTP 404.

### Mixed Content (A+ — 100/100)

*No mixed content detected — all resources use HTTPS.*

- **[PASS]** No mixed content detected — all resources use HTTPS

### Open Graph (A — 90/100)

*Open Graph tags are well configured for social sharing.*

- **[CRITICAL]** og:image is not reachable — The og:image URL could not be fetched. Social platforms won't be able to display it.

### Open Graph / Twitter Card Depth (A+ — 100/100)

*OG image dimensions and Twitter card configuration look healthy*

- **[PASS]** OG/Twitter Card depth is clean -- dimensions, card type, and inheritance all valid

### Structured Data (C — 40/100)

*No structured data (JSON-LD) found.*

- **[INFO]** No structured data (JSON-LD) found — Adding structured data helps search engines understand your content and can enable rich results.

### Rich Results Eligibility (C — 75/100)

*No JSON-LD found -- no rich-result eligibility*

- **[INFO]** No JSON-LD structured data on the page — No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

### Image Optimization (F — 45/100)

*5 issues found across 24 images*

- **[WARNING]** 3 images significantly larger than display size — Resizing to display dimensions could save approximately 93 KB.
- **[WARNING]** 24 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 3 of 24 images use legacy formats
- **[WARNING]** 17 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[INFO]** 8 image(s) wider than 400px without srcset (no responsive serving) — These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://images.ctfassets.net/8aevphvgewt8/1uXZYDy7dMcH9QwxuAU06F/1cb167cc60d725b8cf7089faf9a4ed06/accordion-2-730955545f07.webp, https://images.ctfassets.net/8aevphvgewt8/3xzVZaJhqo3B62R8NeHjX2/e37c81e4f26e9dac2aff1f23a0243087/accordion-3-52ca331d22ea.webp, https://images.ctfassets.net/8aevphvgewt8/3cgNgdKFqflI27vyDh4Gpa/c459dc8690133e7663b8db2626cf2045/accordion-4-a26744b70ff7.webp (+5 more).

*No subdomain takeover risk detected*

- **[PASS]** No CNAME record present

### DNSSEC (B — 80/100)

*Unsigned (DNSSEC not deployed)*

- **[INFO]** DNSSEC is not deployed — The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

### CAA Records (A — 90/100)

*issue: digicert.com, globalsign.com, letsencrypt.org, sectigo.com | issuewild: digicert.com, letsencrypt.org, sectigo.com*

- **[PASS]** CAA issue tag present — authorized CA(s): digicert.com, globalsign.com, letsencrypt.org, sectigo.com
- **[INFO]** No CAA iodef tag — won't be notified of failed issuance attempts — Add `0 iodef "mailto:security@example.com"` to receive notifications when a CA refuses issuance because it doesn't match your CAA policy. Useful signal for detecting issuance attempts by unauthorized CAs.

### Reverse DNS (B — 75/100)

*0/1 IPs match cert SAN*

- **[INFO]** PTR for 140.82.116.3 does not match any cert SAN: lb-140-82-116-3-sea.github.com — Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.

### Multi-Resolver DNS Speed (A+ — 100/100)

*Mean 7ms across 3 resolvers (spread 12ms)*

- **[PASS]** Quad9: 3ms
- **[PASS]** Cloudflare: 5ms

### Crawlability (B — 80/100)

*robots.txt present, no sitemap*

- **[PASS]** robots.txt is present
- **[INFO]** No sitemap.xml found — A sitemap helps search engines discover and index your pages more efficiently.
- **[INFO]** robots.txt does not reference a sitemap — Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

### URL Variants (A+ — 100/100)

*www/non-www, trailing slash, HTTP→HTTPS*

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
- **[PASS]** HTTP correctly 301-redirects to HTTPS

### Domain Intelligence (A+ — 100/100)

---

## Availability

### CDN & Delivery (D — 50/100)

*No CDN detected*

- **[WARNING]** No CDN detected — A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (B — 75/100)

*max-age=0, private, must-revalidate*

- **[PASS]** Cache-Control header is set
- **[PASS]** ETag present — enables conditional (304) responses

### Operational Status Page (A+ — 100/100)

*Status page detected via anchor text*

- **[PASS]** Status page link found: https://www.githubstatus.com

### Transport Security (A — 90/100)

*HTTP/3, HSTS, and TLS version analysis*

- **[INFO]** HTTP/3 (QUIC) not advertised — HTTP/3 eliminates head-of-line blocking. If your CDN supports it, consider enabling it.
- **[PASS]** HSTS enabled (includeSubDomains, preload)
- **[PASS]** HSTS preload enabled
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### Health Check Endpoint (A+ — 100/100)

*Health endpoint at https://github.com/health (HTTP 200)*

- **[PASS]** Public health endpoint at https://github.com/health

### CDN Cache Observability (B — 85/100)

*No CDN cache-status headers in the response*

- **[INFO]** No CDN cache-status headers in the response — Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.

## Accessibility

### Landmark Structure (A — 90/100)

*18 landmarks*

- **[PASS]** <main> landmark present
- **[PASS]** 7 <nav> landmark(s) found
- **[PASS]** All <nav> elements are properly labeled
- **[PASS]** Skip navigation link present
- **[WARNING]** Skip link target(s) don't exist on page: #start-of-content — The skip-link anchor (e.g., `href="#main"`) points at an ID that has no corresponding element on the page. Activating the link does nothing -- a silent WCAG 2.4.1 failure that the visual link presence hides. Add `id="main"` (or whichever matches the href) to the target landmark.

### Heading Hierarchy (B — 75/100)

*32 headings, 1 skip(s)*

- **[WARNING]** Multiple H1 headings (4 found) — A page should have only one H1. Multiple H1s dilute the document outline.
- **[WARNING]** Heading level skipped: H1 → H3 (missing H2) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
- **[INFO]** 1 hidden heading(s) (aria-hidden)

### Heading Text Quality (A+ — 100/100)

*All 32 heading(s) have substantive, well-formed text*

### Link & Button Quality (C — 68/100)

*2 issue(s) across 155 links and 46 buttons*

- **[WARNING]** 11 link(s) open in new tab without warning — Add '(opens in new tab)' to link text or aria-label.
- **[CRITICAL]** 2 button(s) with no accessible text — Icon-only buttons need an aria-label so screen readers can announce them.
- **[PASS]** 144 link(s) with descriptive text

### Form Input Types (A — 90/100)

*2 input(s) using type=text where a specific type would help*

- **[INFO]** Input "query-builder-test" should use type="search" (currently type="text") — Field name "query-builder-test" suggests type="search". Wrong type loses mobile keyboard hints, browser autofill, and free format validation. Change to <input type="search">.
- **[INFO]** Input "custom_scope_query" should use type="search" (currently type="text") — Field name "custom_scope_query" suggests type="search". Wrong type loses mobile keyboard hints, browser autofill, and free format validation. Change to <input type="search">.

### Form Input Quality (A+ — 100/100)

*7 form control(s) checked, no input-semantic issues*

- **[PASS]** All form input semantics look correct

### Iframe Accessibility (A+ — 100/100)

*No iframes on this page*

- **[PASS]** No iframes on this page

### Tap Target Adequacy (C — 75/100)

*4 tap target(s) too small or too close together*

- **[WARNING]** 4 tap target(s) too small or too close to neighbors — WCAG 2.5.5 (Level AAA) requires interactive targets to be at least 44x44 CSS pixels; WCAG 2.5.8 (Level AA, added in 2.2) requires 24x24 minimum. Failing targets cause mis-taps for users with motor impairments, large fingers, or shaky hands -- and are a major bounce-rate driver on mobile commerce flows. Lighthouse measures rendered rects + adjacent-element spacing; the failing list is in the Lighthouse 'tap-targets' audit detail panel.

### Mobile-Readable Font Sizes (A+ — 100/100)

*All 162 visible text node(s) render at >= 12 CSS pixels*

- **[PASS]** All text uses legible mobile font sizes (>= 12 CSS px)

- **[PASS]** Name present: GitHub
- **[PASS]** 192x192 icon present
- **[PASS]** 512x512 icon present
- **[PASS]** Display mode: standalone

### PWA Depth (A — 90/100)

*2 PWA signal(s) surfaced*

- **[INFO]** Manifest has no maskable icon — Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).
- **[INFO]** Manifest is missing `theme_color` — Without `theme_color`, the install prompt and Android status bar fall back to a generic tint instead of your brand color. Add a hex color (e.g. `"theme_color": "#0066cc"`); for richer support, mirror it via `<meta name="theme-color" content="#0066cc">` so non-installed browsers also pick it up.

### Dark Mode Support (B — 80/100)

*Dark mode detected*

- **[PASS]** color-scheme meta tag present — The site declares support for light and dark color schemes via <meta name='color-scheme'>.
- **[INFO]** Theme-color present but no dark variant — A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.
- **[INFO]** Detection limited to meta tags and inline styles — External CSS files may contain prefers-color-scheme rules not visible to this scan.

### Print Stylesheet (D — 40/100)

*No print styles*

- **[INFO]** No print-specific styles detected — When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

### Navigation UX (F — 35/100)

*1 navigation pattern(s)*

- **[PASS]** Skip navigation link detected
- **[PASS]** 7 navigation landmark(s) detected

### Mobile UX Depth (A+ — 100/100)

*2 mobile-depth signal(s) detected*

- **[PASS]** iOS smart-banner opt-in present (`apple-itunes-app`) — The page declares a companion iOS app via `<meta name="apple-itunes-app" content="app-id=...">`. iOS Safari shows a smart banner offering to open the page in the app, with an unobtrusive 'X' to dismiss. Recommended when you have a published companion app.
- **[PASS]** Browser-chrome `theme-color` meta tag present — The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.

*1 markup-quality issue(s) detected*

- **[INFO]** 2 redundant ARIA role attribute(s) on native semantic element(s) — The W3C "ARIA in HTML" spec calls this its first rule: don't use ARIA when a native HTML element already conveys the semantics. `<button role="button">`, `<a href role="link">`, `<nav role="navigation">`, `<main role="main">` -- the role attribute either does nothing or shadows the native semantic, occasionally breaking assistive-tech behaviors. Remove the redundant role.

## Sustainability

### CO2 Per Page Load (D — 50/100)

*1.25g CO2 per view*

- **[WARNING]** 1.25g CO2 per page view — This page transfers 4.4 MB, producing an estimated 1.25g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.23g, network 0.22g, end-user device 0.80g.
- **[INFO]** At 10,000 monthly views: 149.8 kg CO2/year — With 10,000 page views per month, this page would generate approximately 149.8 kg of CO2 annually — equivalent to charging 18725 smartphones.

### Green Hosting (D — 40/100)

*Not green*

- **[INFO]** No confirmed renewable energy commitment detected — Consider providers like Cloudflare, Google Cloud, or Vercel that match 100% of their energy use with renewables.
- **[INFO]** Green hosting status based on known provider commitments — Green hosting detection uses a curated database of provider renewable energy commitments. This is not a real-time verification. For authoritative checks, visit thegreenwebfoundation.org.

### Repeat Visit Weight (A+ — 100/100)

*97% cached*

- **[PASS]** 97% reduction on repeat visits — Returning visitors download only 128 KB (vs 4513 KB first visit). 146 of 147 resources are served from browser cache, saving 1.21g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.04g CO2 (first visit: 1.25g)

### Carbon Budget (D — 50/100)

*68th percentile*

- **[WARNING]** 1.25g CO2 — above the median website (0.60g) — Heavier than an estimated 32% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 68th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (B — 80/100)

*83% efficient*

- **[INFO]** Transfer efficiency: 83% — An estimated 788 KB (17%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 788 KB of unused JavaScript. This wasted data produces 0.22g of unnecessary CO2 per page view.

### Web Font Weight Variants (B — 90/100)

*No detectable Google Fonts weights*

- **[INFO]** No detectable Google Fonts weights — The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
