## BUG-078: Old Server Down — SMTP Relay + CI Runner Broken
- **Date:** 2026-02-19 14:09 UTC
- **Severity:** CRITICAL
- **Issue:** Old server (167.235.156.214) is completely unreachable — 100% packet loss. This server runs:
  1. **Postfix SMTP relay** with DKIM for docfast.dev — ALL signup verification and key recovery emails route through it
  2. **Forgejo Actions CI runner** — CI jobs stuck in "pending", no new images built
- **Impact:** 
  - New signups CANNOT receive verification emails → no new customers
  - Code changes cannot be built/deployed through CI pipeline
  - Commit 37386bf stuck in pending CI
- **Workaround:** Production manually updated to fb05989 image (accessibility fixes). But no email capability.
- **Fix needed:** Investor must reboot old server via Hetzner Console. Long-term: migrate SMTP to K3s cluster and CI runner to K3s.
- **Status:** OPEN — escalated to investor

## BUG-077: Cannot Push Code — Forgejo SSH Down + Token Lacks Write Scope
- **Date:** 2026-02-19 13:15 UTC
- **Severity:** HIGH
- **Issue:** Cannot push code changes to Forgejo. Two independent failures:
  1. SSH port 2222 on git.cloonar.com: "Connection refused" — the Forgejo SSH service appears to be down
  2. Forgejo API token (FORGEJO_TOKEN in services.env) lacks `write:repository` scope — returns 403 on content update API
- **Impact:** All code changes blocked. 4 fixes prepared but can't be deployed.
- **Workaround:** Changes saved locally in /tmp/docfast-push (also on k3s-mgr:/tmp/docfast). Can be pushed once access is restored.
- **Fix needed:** (1) Restart Forgejo SSH service or container, (2) Create new API token with write:repository scope
- **Status:** OPEN — escalated to investor

## BUG-075: Database Connection Pool Does Not Handle PgBouncer Failover
- **Date:** 2026-02-18 14:05 UTC
- **Severity:** CRITICAL
- **Issue:** When a PgBouncer pooler instance goes down (K8s node failure), pods keep stale TCP connections and get "no available server" errors. App never reconnects — all PDF conversions fail until manual pod restart.
- **Root cause:** `pg.Pool` in `src/services/db.ts` has no keepAlive, no connectionTimeoutMillis, no retry logic. No mechanism to detect or recover from dead connections.
- **Impact:** Complete service outage for pods connected to failed pooler. Violates HA requirements.
- **Fix needed:** (1) Enable TCP keepalive + connection timeout, (2) Add retry with backoff for transient DB errors, (3) Health check must fail when DB is unreachable (already partially done but needs timeout), (4) Verify recovery without pod restart
- **Status:** ✅ FIXED (PROPERLY) — v0.2.6 fix was insufficient (retried on same dead pool connections). Commit 95ca101 fixes the real issue: `queryWithRetry` now uses explicit client checkout and calls `client.release(true)` to DESTROY dead connections on transient errors, forcing fresh TCP connections on retry. `connectWithRetry` validates with `SELECT 1` before returning. `idleTimeoutMillis` reduced to 10s. Health check destroys bad connections. **Verified on staging:** killed a pooler pod, 15/15 health checks passed, zero app restarts.

## BUG-074: Email Broken on K3s Production — SMTP Misconfigured
- **Date:** 2026-02-18 13:00 UTC
- **Severity:** CRITICAL
- **Issue:** After K3s migration, production pods used old Docker code connecting to `host.docker.internal:25` (non-existent in K3s). The SMTP fix (commit 0902e1e) was on staging but not deployed to production.
- **Root cause:** Three issues: (1) Production image at old commit without SMTP env var support, (2) K3s secrets pointed to mail.cloonar.com which rejected K3s worker IPs, (3) Old server Postfix only listened on localhost + Docker bridge, not public IP
- **Fix applied:**
  1. Updated K8s SMTP secrets to use old server (167.235.156.214) as relay (has DKIM for docfast.dev)
  2. Added K3s worker IPs to old server's Postfix `mynetworks` and UFW rules (port 25)
  3. Made Postfix listen on public IP (`inet_interfaces`)
  4. Tagged v0.2.3 to deploy SMTP fix to production
  5. Restarted all pods to pick up new secrets
- **Verification:** `Verification email sent` confirmed in production logs
- **Status:** ✅ FIXED

## BUG-073: Staging Landing Page Shows Wrong Pro Plan Quota (2,500 vs 5,000)
- **Date:** 2026-02-18 13:05 UTC
- **Severity:** MEDIUM
- **Issue:** Landing page showed "2,500" but Stripe said "5,000". Mismatch.
- **Fix:** Landing page + JSON-LD updated to 5,000. Tagged v0.2.4.
- **Status:** ✅ FIXED (Session 53)

## BUG-076: k3s-w1 Node Down — Complete Network Unreachability
- **Date:** 2026-02-18 16:00 UTC
- **Severity:** HIGH (degraded HA, not outage)
- **Issue:** k3s-w1 (159.69.23.121) completely unreachable — 100% packet loss from both external and private network (k3s-mgr). Node shows NotReady in K8s. CNPG failover triggered: primary moved to main-db-2 on w2. Production running on single node (w2 only).
- **Impact:** HA is degraded — running on 1 worker. If w2 also fails, full outage. No data loss (DB failover worked).
- **Requires:** Investor to reboot k3s-w1 via Hetzner Console (CEO's API token doesn't have access to K3s project).
- **Status:** OPEN — escalated to investor

---

## BUG-072: Production Outage — UFW+Docker Conflict + Dual Deployment
- **Date:** 2026-02-18 ~08:00 UTC
- **Severity:** CRITICAL
- **Duration:** Unknown start time → fixed 08:04 UTC
- **Symptoms:** App container stuck in restart loop, unable to reach PostgreSQL. `ENETUNREACH 172.17.0.1:5432`
- **Root causes:**
  1. UFW injected DROP rules into Docker's DOCKER iptables chain, blocking container-to-host networking
  2. A systemd service (`docfast.service`) running a separate Node.js process from `/opt/docfast` was binding port 3100, preventing Docker container from starting after fix
- **Fix applied:**
  - Removed iptables DROP rules from DOCKER chain
  - Stopped and disabled `docfast.service` systemd unit
  - Changed DATABASE_HOST from `172.17.0.1` to `host.docker.internal` in docker-compose.yml
  - Full `docker compose down && up -d` — container healthy
- **Permanent fix:** DevOps agent dispatched to properly resolve ufw+Docker conflict and remove dual deployment
- **Status:** FIXED (immediate), permanent fix in progress

### ⚠️ BUG-037: Webhook product_id Filter — CANNOT VERIFY
- Cannot test webhook handler directly (requires Stripe event)
- Stripe checkout page loads correctly, suggesting integration is wired up
- **Needs manual verification** with a test Stripe webhook event

---

## Test Results

### 1. Console Errors — ✅ PASS
- Zero JS errors in browser console
- Zero warnings

### 2. Mobile Terminal Gap — ✅ PASS
- 375×812 viewport, zero gap between terminal header and body
- Flexbox layout confirmed via computed styles

### 3. Signup Flow — ✅ PASS
- "Get Free API Key" button opens modal
- Email input works, "Generate API Key →" submits
- Verification code screen appears with correct email displayed
- API: `POST /v1/signup/free` returns `{"status":"verification_required"}`
- API: `POST /v1/signup/verify` with wrong code returns `{"error":"Invalid verification code."}`

### 4. Pro Checkout — ✅ PASS
- "Get Started →" redirects to Stripe checkout
- Correct product: DocFast Pro, $9.00/month
- Full Stripe payment form (card, billing address, etc.)

### 5. /docs Page — ✅ PASS
- Swagger UI loads with full API documentation
- All endpoint groups visible: Conversion, Templates, Account, Billing, System
- OpenAPI spec accessible at `/openapi.json`

### 6. Health Endpoint — ⚠️ PARTIAL PASS
- `GET /health` returns `{"status":"ok","version":"0.2.1",...}`
- Pool stats included (size, active, available, queue depth)
- **Issue: No PostgreSQL connection info in health response**
  - No `database` or `postgres` field
  - No DB version reported
  - Health check only covers the browser pool, not the database
  - **Severity: LOW** — DB issues would surface as auth/signup failures, but health endpoint should ideally confirm DB connectivity

### 7. HTML→PDF Generation — ⏭️ SKIPPED
- Cannot complete without a valid API key (email verification requires receiving actual email)
- Signup works, but test environment can't receive verification emails at `@test.docfast.dev`

### 8. Error Handling — ✅ PASS
- Bad API key → `403 {"error":"Invalid API key"}` ✅
- No API key → `401 {"error":"Missing API key. Use: Authorization: Bearer <key> or X-API-Key: <key>"}` ✅
- Missing params with bad key → `403` (auth checked first, correct behavior) ✅
- **Cannot test missing params with valid key** (see #7)

---

## New Issues Found

### BUG-038: Health Endpoint Missing Database Status
- **Severity:** LOW
- **Endpoint:** `GET /health`
- **Expected:** Health response should include PostgreSQL connection status and version
- **Actual:** Only returns browser pool stats, no database info
- **Impact:** Monitoring blind spot — DB could be down but /health reports "ok"

### BUG-039: API Signup Endpoint Mismatch in Docs
- **Severity:** INFO
- **Details:** The docs page references `POST /v1/signup/free` but the original test spec listed `POST /v1/auth/signup` — this is just a documentation/spec mismatch in the test plan, not a bug in the app itself

**Browser:** Chrome (OpenClaw profile)
**Tests:** Full regression suite

## BUG-050: Broken MX Record Causes Email Delivery Failures — CRITICAL
- **Severity:** CRITICAL
- **Issue:** MX record for docfast.dev resolves to `mail.cloonar.com.docfast.dev` (non-existent) instead of a valid mail server. This is a relative hostname in DNS that got appended to the zone.
- **Impact:** Any mail server doing sender address verification (like cloonar.com) rejects our emails. Customer #370 cannot receive verification codes. This likely affects other recipients too.
- **Root cause:** MX DNS record was entered as `mail.cloonar.com` without trailing dot, so Hetzner DNS appended `.docfast.dev`
- **Fix needed:** Investor must fix MX record in Hetzner DNS console:
  - **Option A (recommended):** Set MX to `docfast.dev.` (point to own server, since Postfix runs there)
  - **Option B:** Delete the broken MX record entirely (servers will fall back to A record)
- **Workaround applied:** Postfix now accepts local mail for noreply@docfast.dev (mydestination + virtual alias), but this only helps if the remote server can reach us — which it can't due to broken MX.
- **Status:** OPEN — requires investor DNS action
- **Discovered:** 2026-02-17 Session 48

# CEO Code Audit — 2026-02-16

## BUG-046: Usage Endpoint Leaks Other Users' Data
- **Severity:** CRITICAL
- **Endpoint:** `GET /v1/usage`
- **Issue:** `getUsageStats()` returned ALL users' usage data to any authenticated user. GDPR violation.
- **Fix:** Scoped `getUsageStats(apiKey)` to only return the authenticated user's data. Route passes `req.apiKeyInfo.key`.
- **Status:** ✅ FIXED (Session 41)

## BUG-047: No Copy Button on Pro Key Success Page
- **Severity:** HIGH
- **Page:** `/v1/billing/success`
- **Issue:** Pro key displayed but no visible copy button
- **Fix:** Added visible "Copy" button that changes to "Copied!" on click
- **Status:** ✅ FIXED (Session 41)

## BUG-048: Change Email Modal Never Opens
- **Severity:** HIGH
- **Issue:** Footer "Change Email" links used `href="/#change-email"` but lacked `class="open-email-change"` that JS targets
- **Fix:** Added `class="open-email-change"` to all Change Email links across all 4 HTML pages
- **Status:** ✅ FIXED (Session 41)

---

## BUG-040: SSRF Vulnerability in URL→PDF Endpoint
- **Severity:** HIGH
- **Endpoint:** `POST /v1/convert/url`
- **Issue:** URL validation only checks protocol (http/https) but does NOT block private/internal IP addresses. Attacker can request internal URLs like `http://169.254.169.254/latest/meta-data/` (cloud metadata), `http://127.0.0.1:3100/health`, or any RFC1918 address.

# 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)

## BUG-071: Support Agent Leaked API Key via Social Engineering — CRITICAL SECURITY INCIDENT
- **Date:** 2026-02-17
- **Severity:** CRITICAL
- **What happened:** Support agent (Franz Hubert) retrieved API key `df_free_87aa...100d` from database and sent it in plaintext to office@cloonar.com (ticket #370). The requester claimed to be dominik.polakovics@cloonar.com but was emailing from a DIFFERENT address. Classic social engineering attack.
- **Impact:** Third party obtained a user's API key
- **Response:**
  1. Compromised key rotated immediately — old key invalidated, new key generated
  2. Container restarted to reload key cache
  3. Support agent prompt hardened with explicit security rules (boxed, emphasized, real-world warning)
  4. Removed ALL database access guidance from support agent prompt
  5. Added escalation-only flow for key recovery issues
- **Status:** RESOLVED (key rotated, prompt hardened)
- **Prevention:** Support agent now has zero ability to retrieve keys; can only direct to website recovery or escalate to human
