+# QA Audit — Session 48
+
+**Tester:** QA Subagent (deep audit)
+**Date:** 2026-02-17 08:00–08:30 UTC
+**URL:** https://docfast.dev
+**Version:** 0.2.1
+**Scope:** Performance · SEO · Accessibility · Cross-page Consistency
+

+
+## 🔴 PERFORMANCE AUDIT
+
+### BUG-051: Duplicate HTTP Response Headers — Nginx Misconfiguration
+- **Severity:** MEDIUM
+- **Affected:** All responses (HTML, JS, PNG)
+- **Issue:** Two headers appear twice in every HTTP response:
+  - `Vary: Accept-Encoding` — appears twice in HTML response
+  - `X-Content-Type-Options: nosniff` — appears twice in all responses
+- **Root cause:** Likely set in both the nginx base config and the application (Express helmet)
+- **Impact:** RFC violation; some proxies may mishandle duplicate headers; wasted bytes
+- **Fix:** Remove duplicate from one layer (either nginx or helmet)
+
+### BUG-052: Duplicate `Cache-Control` Headers on Static Assets
+- **Severity:** MEDIUM
+- **Affected:** `app.js`, `status.js`, `og-image.png`
+- **Issue:** Two conflicting Cache-Control headers are returned simultaneously:
+  - `Cache-Control: max-age=604800` (without `public`)
+  - `Cache-Control: public, max-age=604800, immutable`
+- **Impact:** Proxy/CDN behavior is undefined when two Cache-Control headers conflict; should be a single directive
+- **Fix:** Consolidate to one header: `Cache-Control: public, max-age=604800, immutable`
+
+### BUG-053: JavaScript Files Not Minified
+- **Severity:** LOW
+- **Files:** `/app.js` (515 lines, 16,838 bytes), `/status.js` (48 lines, 3,285 bytes)
+- **Issue:** Both JS files are served unminified with readable variable names, full whitespace, and comments
+- **Impact:** ~30–40% larger payload than necessary; slower parse time (minor for these sizes)
+- **Fix:** Add a build step: `terser app.js -o app.min.js` and update HTML references
+
+### BUG-054: No Brotli Compression — Gzip Only
+- **Severity:** LOW
+- **Issue:** Server only supports gzip compression; does not serve Brotli (`Content-Encoding: br`) even when `Accept-Encoding: br` is sent
+- **Impact:** Brotli compresses ~20–26% better than gzip for text assets; Chrome and all modern browsers support it
+- **Fix:** Enable `brotli_static` in nginx or add `compression` middleware with Brotli support
+
+### BUG-055: Duplicate `<link rel="preconnect">` Tags in Homepage HTML
+- **Severity:** LOW
+- **Issue:** The homepage HTML includes the Google Fonts preconnect hint twice:
+  - Line 17: `<link rel="preconnect" href="https://fonts.googleapis.com">` (in `<head>`, no actual font loaded nearby)
+  - Line 266: `<link rel="preconnect" href="https://fonts.googleapis.com">` (again, right before the stylesheet)
+  - Same duplication for `https://fonts.gstatic.com`
+- **Impact:** Wasted browser hint; negligible but signals copy-paste error in template
+- **Fix:** Remove the first set (lines ~17–18); keep only the preconnect immediately before the font `<link>`
+
+---
+
+## 🟡 SEO AUDIT
+
+### BUG-056: Sitemap Namespace URL Typo — Invalid Sitemap
+- **Severity:** HIGH
+- **File:** `https://docfast.dev/sitemap.xml`
+- **Issue:** Sitemap uses wrong namespace: `http://www.sitemapns.org/schemas/sitemap/0.9`
+  - Correct URL: `http://www.sitemaps.org/schemas/sitemap/0.9`
+  - Difference: `sitemapns.org` vs `sitemaps.org` (extra "n")
+- **Impact:** Google Search Console will reject this sitemap as invalid XML schema. Crawlers that validate the namespace may ignore it entirely.
+- **Fix:** Change `sitemapns.org` → `sitemaps.org` in the sitemap XML
+
+### BUG-057: JSON-LD Structured Data Has Stale Pro Plan Description
+- **Severity:** MEDIUM
+- **Location:** `<script type="application/ld+json">` in homepage `<head>`
+- **Issue:** JSON-LD Pro offer says `"description": "5,000 PDFs per month"` but:
+  - The landing page shows 10,000 PDFs per month for Pro
+  - BUG-045 (previously fixed) updated Stripe to say "10,000 PDFs per month"
+  - The JSON-LD was never updated — still shows the old 5,000 figure
+- **Impact:** Google may display incorrect pricing/quota info in rich results
+- **Fix:** Update JSON-LD Pro offer description to `"10,000 PDFs per month"`
+
+### BUG-058: twitter:image Meta Tag Missing on Homepage
+- **Severity:** LOW
+- **Location:** `<head>` of `https://docfast.dev/`
+- **Issue:** Homepage has `og:image` set to `/og-image.png` ✅ but the corresponding `<meta name="twitter:image">` tag is absent
+- **Impact:** Twitter/X link previews won't show the card image even though the image exists and og:image is set (Twitter prefers its own tags when present)
+- **Fix:** Add `<meta name="twitter:image" content="https://docfast.dev/og-image.png">`
+
+### BUG-059: `/docs` Page Missing All SEO Meta Tags
+- **Severity:** MEDIUM
+- **URL:** `https://docfast.dev/docs`
+- **Issue:** The docs page (Swagger UI) has:
+  - No `<meta name="description">` ❌
+  - No `<link rel="canonical">` ❌
+  - No og: tags ❌
+  - No twitter: tags ❌
+  - Title: "DocFast API Documentation" (inconsistent format — others use `Page — DocFast` pattern)
+- **Impact:** Poor search appearance for a high-value SEO target (developers searching for PDF API docs)
+- **Fix:** Add standard meta tags to the `/docs` HTML template
+
+### BUG-060: Sub-pages Missing Open Graph / Twitter Meta Tags
+- **Severity:** LOW
+- **Affected:** `/impressum`, `/privacy`, `/terms`, `/status`
+- **Issue:** These pages have `<title>`, `<meta description>`, and `<canonical>` but no og: or twitter: tags
+- **Impact:** Unfriendly link previews when shared on social media
+- **Fix:** Add at minimum `og:title`, `og:description`, `og:url` to each sub-page template
+
+### BUG-061: `/status` Page Not Included in Sitemap
+- **Severity:** INFO
+- **URL:** `https://docfast.dev/sitemap.xml`
+- **Issue:** The sitemap includes `/`, `/docs`, `/impressum`, `/privacy`, `/terms` but omits `/status`
+- **Impact:** Minor — status pages are generally low SEO priority, but consistency is good
+- **Fix:** Add `/status` to sitemap with `changefreq=always` and low priority (0.2)
+
+---
+
+## 🟠 ACCESSIBILITY AUDIT
+
+### BUG-062: `<main>` Element Only Wraps Hero Section
+- **Severity:** HIGH
+- **Location:** `https://docfast.dev/` (lines 283–309)
+- **Issue:** The `<main>` landmark element only wraps the hero (headline + CTA + code block). The trust stats, EU hosting badge, features grid, and pricing section are all **outside** `<main>` — they're bare `<section>` elements after `</main>`
+- **Impact:** Screen reader users using "jump to main content" will skip to the hero and miss the features/pricing. WCAG 1.3.6 landmark best practice violation.
+- **Fix:** Extend `<main>` to wrap all page content between nav and footer
+
+### BUG-063: Heading Hierarchy Skip — h3 Without Parent h2
+- **Severity:** MEDIUM
+- **Location:** "Hosted in the EU" section (homepage)
+- **Issue:** Page structure: `<h1>` (hero) → `<h3>` "Hosted in the EU" → `<h2>` "Everything you need". The h3 appears before the first h2, violating sequential heading order (WCAG 1.3.1, Success Criterion: Info and Relationships)
+- **Impact:** Screen readers announce heading levels; skipping from h1 to h3 confuses navigation
+- **Fix:** Change the "Hosted in the EU" heading from `<h3>` to `<h2>`, or restructure so it follows an h2
+
+### BUG-064: Modal Form Inputs Have No `<label>` Elements
+- **Severity:** HIGH
+- **Location:** All three modals (Sign Up, Recover API Key, Change Email)
+- **Issue:** Every `<input>` in the modals uses only `placeholder` text for labeling. There are no `<label for="...">` elements and no `aria-label` or `aria-labelledby` attributes on the inputs
+- **Impact:** WCAG 1.3.1, 3.3.2 violations. Screen readers will announce inputs with only their placeholder (which vanishes on focus/input), making the form inaccessible for blind users
+- **Fix:** Add `<label>` elements for each input, or add `aria-label` attributes:
+  ```html
+  <label for="signupEmail" class="sr-only">Email address</label>
+  <input type="email" id="signupEmail" ...>
+  ```
+
+### BUG-065: Modal Close Buttons Have No Accessible Label
+- **Severity:** MEDIUM
+- **Location:** All three modal close buttons (`id="btn-close-signup"`, `btn-close-recover`, `btn-close-email-change`)
+- **Issue:** Buttons render `×` (HTML entity `&times;`) with no `aria-label` attribute
+- **Impact:** Screen readers will announce "times" or "multiplication sign" instead of "Close". WCAG 4.1.2 violation.
+- **Fix:** Add `aria-label="Close dialog"` to each close button
+
+### BUG-066: Modals Missing `aria-modal="true"`
+- **Severity:** MEDIUM
+- **Location:** `#signupModal`, `#recoverModal`, `#emailChangeModal`
+- **Issue:** Modal divs have `role="dialog"` but lack `aria-modal="true"`. Without `aria-modal`, screen readers (especially NVDA/JAWS in browsing mode) may continue reading background content
+- **Impact:** Background page content is announced while modal is open
+- **Fix:** Add `aria-modal="true"` to all three modal overlay divs
+
+### BUG-067: No Skip-to-Content Link
+- **Severity:** LOW
+- **Issue:** There is no "Skip to main content" link at the top of any page. Keyboard users must tab through the entire navigation on every page load to reach the main content
+- **Impact:** WCAG 2.4.1 (Bypass Blocks) — Level A violation. Particularly problematic since there is a 3-item nav on every page.
+- **Fix:** Add as first element in `<body>`:
+  ```html
+  <a href="#main-content" class="skip-link">Skip to main content</a>
+  ```
+
+---
+
+## 🔵 CROSS-PAGE CONSISTENCY AUDIT
+
+### BUG-068: "Change Email" Footer Link Broken on Sub-pages
+- **Severity:** MEDIUM
+- **Affected:** `/impressum`, `/privacy`, `/terms`, `/status`
+- **Issue:** The footer "Change Email" link (`href="/#change-email"` + `class="open-email-change"`) works on the **homepage** because `app.js` intercepts the click and opens the modal. On sub-pages, `app.js` is **not loaded**, so clicking navigates to `https://docfast.dev/#change-email`. The homepage `app.js` DOMContentLoaded handler does not check `window.location.hash` on load, so the modal never auto-opens.
+- **Note:** BUG-048 (previous session) added the `class="open-email-change"` to these links, but the incomplete fix only works on the homepage itself. Sub-page navigation to `/#change-email` falls through silently.
+- **Impact:** Users on sub-pages who want to change their email get taken to the homepage with no modal — confusing dead end
+- **Fix:** Either (a) add hash detection in app.js DOMContentLoaded: `if (window.location.hash === '#change-email') openEmailChange();`, or (b) add a standalone mini-script to sub-pages that handles the click and redirects with a proper action param
+
+### BUG-069: `/docs` Page Uses Different Navigation Pattern
+- **Severity:** INFO
+- **URL:** `https://docfast.dev/docs`
+- **Issue:** The docs page uses a custom Swagger UI top bar with "← Back to docfast.dev" instead of the main site nav (Features, Pricing, Docs links). Footer is also absent.
+- **Note:** This is intentional for SwaggerUI but means the docs page is an isolated island with no footer navigation and no way to reach /status, /impressum, /privacy, or /terms from docs
+- **Impact:** Low — power users know to use the browser back button; but /impressum and /privacy should be reachable from all pages (legal requirement in some jurisdictions)
+- **Fix:** Add a minimal footer to the /docs page with legal links (Impressum, Privacy, Terms)
