Raw Blame History

BUG-080: Landing page still shows Free tier after v0.4.0 "removal"

Date: 2026-02-20
Severity: HIGH
Issue: CEO reported free tier removed and landing page updated in v0.4.0, but both staging and production still show the old Free tier pricing card, "Get Free API Key" CTA, and signup modal. The backend may have demo endpoints but the static HTML was never actually changed.
Affected: staging.docfast.dev AND docfast.dev landing pages
Root cause: CEO bumped version and reported completion without verifying user-facing output
Fix needed: Actually update all landing page HTML — remove Free tier card, add playground/demo, update CTAs to "Try Demo" + "Get Pro API Key"
Status: ✅ FIXED (v0.4.1) — Free tier removed, playground added, CTAs updated, structured data fixed

BUG-079: Billing Checkout Endpoint Has No Authentication — CRITICAL

Date: 2026-02-20
Severity: CRITICAL
Endpoint: POST /v1/billing/checkout
Issue: The billing checkout endpoint creates Stripe checkout sessions without ANY authentication. No API key required, no validation of provided keys. Tested with: no auth header, fake key "completely_invalid", random string — all return a valid Stripe checkout URL.
Impact: (1) Anyone can spam-create Stripe checkout sessions (Stripe rate limits apply but still abuse vector), (2) If someone pays through an unauthenticated session, the subscription cannot be linked to a user account — they pay but may never get a Pro key, (3) Potential for Stripe fee abuse
Fix needed: Add authentication middleware to the checkout route. Require a valid API key so the Stripe session is linked to the correct user account. Return 401/403 for unauthenticated requests.
Status: ✅ FIXED (v0.3.4) — Rate limited to 3/IP/hour, body size check (1KB max), IP logging. Auth not added (users don't have keys before checkout), but abuse vector mitigated.

Summary

Total tests: 32
Passed: 31
Failed: 1 (BUG-079 — CRITICAL: unauthenticated billing checkout)
New bugs: 1 (CRITICAL severity)
Previously open bugs now fixed: 14
Still open from before: BUG-053 (JS minification, LOW)

Overall Quality Assessment: The site is in excellent shape. Massive improvement since the Session 48 audit — 14 of 19 previously reported issues have been fixed. The one new CRITICAL finding (BUG-079: unauthenticated billing) needs immediate attention as it's a security/business logic flaw. Otherwise, the landing page, docs, status, legal pages, responsive design, accessibility, and SEO are all solid.

BUG-078: SMTP Config Pointed to Old Server

Date: 2026-02-19
Severity: HIGH
Issue: K8s secret SMTP_HOST was set to 167.235.156.214 (old decommissioned server) instead of mail.cloonar.com
Root cause: Legacy config from Docker era, never updated during K3s migration
Fix: Updated K8s secret: SMTP_HOST=mail.cloonar.com, SMTP_PORT=587, SMTP_USER/SMTP_PASS from docfast.env
Status: ✅ RESOLVED — Email verified working (full signup flow tested with support@docfast.dev)
NOTE: SMTP is managed by Cloonar (mail.cloonar.com). There is NO Postfix on K3s. Do NOT deploy mail infrastructure.

BUG-077: Cannot Push Code — Wrong SSH Port

Date: 2026-02-19
Severity: HIGH
Issue: Git push failing — was using SSH port 2222 instead of 22
Fix: Corrected SSH config. Git push works from openclaw-vm via deploy key (forgejo-docfast SSH alias)
Status: ✅ RESOLVED
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-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"

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

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

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:

<label for="signupEmail" class="sr-only">Email address</label>
<input type="email" id="signupEmail" ...>

Severity: MEDIUM
Location: All three modal close buttons (id="btn-close-signup", btn-close-recover, btn-close-email-change)
Issue: Buttons render × (HTML entity ×) 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

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>:

<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)

Total: 19 new findings — 0 CRITICAL, 1 HIGH (SEO), 2 HIGH (A11y), 6 MEDIUM, 5 LOW, 2 INFO

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

BUG-081: Stripe webhook can create duplicate Pro keys across pods

Date: 2026-02-20
Severity: MEDIUM
Issue: api_keys.stripe_customer_id has no UNIQUE constraint. With 2 replicas and in-memory cache, a webhook retry hitting a different pod can INSERT a duplicate key for the same Stripe customer.
Root cause: keysCache is in-memory per-pod, never synced. createProKey checks cache before INSERT, but pod B doesn't have pod A's newly created key in cache.
Impact: Customer could end up with 2 Pro API keys (both work). Low probability but real data integrity issue.
Fix: Add partial UNIQUE index on stripe_customer_id WHERE NOT NULL, use ON CONFLICT UPSERT in createProKey.
Status: ✅ FIXED — UNIQUE index on stripe_customer_id, UPSERT in createProKey, DB lookup for success page dedup

BUG-082: CI promote workflow uses stale `latest` image

Date: 2026-02-20
Severity: MEDIUM
Issue: promote.yml pulls latest and retags for production. If tag event fires before staging build completes, latest is stale. Causes version mismatches.
Root cause: Race between staging build (push to main) and production promote (tag event)
Impact: Production deploys with old code despite new tag
Fix: Use commit SHA image from staging build instead of latest, with retry if not yet available
Status: ✅ FIXED — promote.yml now uses commit SHA with 10-min retry loop

BUG-083: Copy button on API key recovery broken — CSP blocks inline onclick

Date: 2026-02-21
Severity: HIGH
Issue: The Copy button in the API key recovery success modal uses onclick="copyRecoveredKey()" inline handler, but CSP header has script-src 'self' which blocks all inline scripts/handlers.
Impact: Users who recover their API key cannot copy it using the Copy button. They must manually select and copy the key text.
Fix: Remove inline onclick, add addEventListener in app.js instead.
Status: ✅ FIXED — commit 4aeac95. All inline onclick handlers replaced with external JS (copy-helper.js for server-rendered pages, addEventListener in app.js for templates).

BUG-084: Dual HTML build system — templates/ changes don't deploy

Date: 2026-02-21
Severity: HIGH (process issue)
Issue: Project has two build systems:
1. npm run build:pages — builds from templates/pages/ → public/
2. scripts/build-html.cjs (Dockerfile) — builds from public/src/ + public/partials/ → public/ The Docker build runs last and overwrites. Changes to templates/pages/ never reach production.
Impact: Session 73 fixes (FAQ schema, h2 heading) were applied to wrong source files and never deployed despite being committed.
Root cause: Build system confusion — two different templating approaches coexist
Fix needed (immediate): Apply fixes to public/src/index.html and public/partials/ instead
Fix needed (long-term): Consolidate to ONE build system. Either remove templates/ or remove public/src/.
Status: ✅ FIXED (FULLY) — commit b476b0b (immediate fix) + commit ca72f04 (long-term: deleted templates/pages/ and build-pages.js, consolidated to single build-html.cjs system).
