BUG-107: Recover route uses in-memory cache only — recovery fails silently across pods

  • Date: 2026-03-06
  • Severity: MEDIUM
  • Issue: POST /v1/recover and /v1/recover/verify use getAllKeys() (in-memory cache) to find a user's key by email. In a 2-replica setup, if the key was created or email changed on another pod, the cache is stale. Recovery silently returns "recovery_sent" without actually sending an email (because it doesn't find the key), or verify returns "No API key found" despite the key existing in DB.
  • Impact: Users may be unable to recover their API key if they hit the "wrong" pod. Silent failure — no error shown.
  • Fix: Fall back to DB query when in-memory lookup fails.
  • Status: ✅ FIXED — commit b964b98. DB fallback in recover/verify endpoint. 2 TDD tests added (recover-db-fallback.test.ts). 520 tests total.

BUG-106: downgradeByCustomer only checks in-memory cache — cancellations can silently fail

  • Date: 2026-03-06
  • Severity: HIGH
  • Issue: downgradeByCustomer() in src/services/keys.ts only checks keysCache (in-memory). In 2-replica production, if a Stripe cancellation webhook hits a pod that doesn't have the key cached (pod restart, key created on other pod), the function returns false without checking DB. Customer keeps Pro access despite canceling their subscription.
  • Impact: Revenue leakage — canceled customers retain Pro tier indefinitely. Silent failure with no error log.
  • Fix: Add DB fallback: query api_keys table by stripe_customer_id when not found in cache, then update tier in DB and hydrate local cache.
  • Status: ✅ FIXED — commit b964b98. DB fallback + cache hydration. 2 TDD tests added (keys-downgrade.test.ts). 520 tests total.

BUG-105: Go and PHP examples show non-existent SDK code

  • Date: 2026-03-05
  • Severity: MEDIUM
  • Issue: Go example used github.com/docfast/docfast-go (doesn't exist), PHP example used DocFast\Client (doesn't exist). Both said "SDK coming soon" but showed SDK code. Developers copying these would get import errors.
  • Fix: Replaced with plain HTTP examples (Go: net/http, PHP: file_get_contents). Removed fake Laravel facade. 5 regression tests added.
  • Status: ✅ FIXED — commit 4f6659c. 484 tests passing, 32 test files.

BUG-104: Terms of Service still references discontinued "Free Tier"

  • Date: 2026-03-05
  • Severity: MEDIUM
  • Issue: public/src/terms.html section 2.1 describes a "Free Tier" with "100 PDF conversions" and "10 requests per minute." Free accounts were discontinued — only a Demo endpoint exists (5 req/hour, no account needed). Section 5.1 also says "no SLA for free tier."
  • Impact: Legal page contradicts actual product offering. Could confuse users or create contractual ambiguity.
  • Fix: Replace Free Tier section with Demo tier description; update SLA reference.
  • Status: ✅ FIXED — commit 503e651. Section 2.1 now describes Demo (Free), section 5.1 updated. 3 regression tests added. 487 tests total, all passing.

BUG-103: Template render route bypasses PDF option validation entirely

  • Date: 2026-03-05
  • Severity: MEDIUM
  • Issue: /v1/templates/:id/render accepts _format and _margin from user input and passes them directly to renderPdf() without going through validatePdfOptions(). All convert routes and demo routes were fixed in BUG-102 to use validated/sanitized options, but the template route was missed. Invalid format values (e.g., "invalid") go straight to Puppeteer.
  • Impact: Users could pass invalid page formats or margin values to template rendering. Puppeteer may reject or silently handle them. Inconsistent validation across API surface.
  • Fix: Import and use validatePdfOptions() in template render route, same pattern as convert/demo routes.
  • Status: ✅ FIXED — commit 47571c8. Added validatePdfOptions() to template render route. 6 TDD tests added (templates-render-validation.test.ts). 479 tests total, all passing. Pushed to main.

BUG-102: Convert/demo routes ignore sanitized PDF options from validator

  • Date: 2026-03-05
  • Severity: MEDIUM
  • Issue: validatePdfOptions() returns { valid: true, sanitized: {...} } with normalized values (e.g., format "a4" → "A4"). But all convert routes (html, markdown, url) and demo routes pass raw body.* values to renderPdf() instead of validation.sanitized.*. Format normalization never takes effect.
  • Impact: Users sending lowercase format like "a4" get it passed raw to Puppeteer. Puppeteer may reject or silently handle it, but the validator's normalization is wasted work.
  • Fix: Use validation.sanitized for PDF options in all convert and demo routes.
  • Status: ✅ FIXED — commit ba2e542. All 5 routes (3 convert + 2 demo) now use validation.sanitized from validatePdfOptions(). 5 TDD tests added (convert-sanitized.test.ts). 473 tests total, all passing. Pushed to main (staging auto-deploy pending CI runner).

BUG-101: Body size limits on demo and convert routes are ineffective — global parser runs first

  • Date: 2026-03-04
  • Severity: MEDIUM
  • Issue: In src/index.ts, the global express.json({ limit: "2mb" }) middleware (line ~85) runs BEFORE route-specific parsers. Express only parses the body once — the first matching parser wins. So the route-specific limits never fire:
    • Demo route: express.json({ limit: "50kb" }) — INEFFECTIVE, actually allows 2MB
    • Convert routes: express.json({ limit: "500kb" }) — INEFFECTIVE, actually allows 2MB
  • Impact: Demo users (unauthenticated) can send 2MB payloads instead of 50KB — free resource abuse vector. Authenticated users can send 2MB instead of 500KB.
  • Verified: Sent 52KB payload to /v1/demo/html on production — got HTTP 200 instead of expected 413.
  • Fix: Remove global JSON parser, apply route-specific parsers before each route group with correct limits.
  • Status: ✅ FIXED — commit c03f217. Removed global express.json(), applied route-specific parsers per-route. 4 TDD tests added (body-limits.test.ts). 468 tests total, all passing. Pushed to main (staging auto-deploy).

BUG-100: Usage flush transaction error handling broken — one bad key poisons entire batch

  • Date: 2026-03-04
  • Severity: MEDIUM
  • Issue: flushDirtyEntries() in src/middleware/usage.ts wraps all usage writes in a single PostgreSQL transaction (BEGIN/COMMIT) with per-key try/catch inside the loop. In PostgreSQL, if any single INSERT fails inside a transaction, the transaction enters an "aborted" state and ALL subsequent queries fail with "current transaction is aborted, commands ignored until end of transaction block." The per-key error recovery is ineffective — one bad key causes all remaining keys in the batch to silently fail.
  • Impact: If any single usage INSERT fails (e.g., constraint violation, type error), ALL remaining usage counts in that flush batch are lost. Could cause usage count divergence between in-memory and DB.
  • Fix: Remove the transaction wrapper and flush each key independently, or use SAVEPOINTs.
  • Status: ✅ FIXED — commit d2f819d. Removed transaction wrapper, each key flushes independently with its own client. 1 TDD test added. 464 tests total, all passing. Pushed to main (staging auto-deploy).

BUG-099: provisionedSessions Set in billing.ts grows unbounded (memory leak)

  • Date: 2026-03-03
  • Severity: LOW
  • Issue: provisionedSessions in src/routes/billing.ts is an unbounded Set<string> that stores every Stripe checkout session ID forever. Used to prevent duplicate key provisioning on success page refresh. DB-level dedup (findKeyByCustomerId) handles correctness across pod restarts, but the in-memory Set grows without bound.
  • Impact: Over months/years, memory usage increases linearly with purchases. Low real-world impact given expected volume, but a code quality issue.
  • Fix: Replace with a TTL Map that auto-expires entries after 24h.
  • Status: ✅ FIXED — commit 5f776db. Replaced Set with TTL Map (24h expiry, hourly cleanup). 4 TDD tests added. 447 tests total, all passing. Pushed to main (staging auto-deploy).

BUG-098: Request interceptor leaks across browser pool pages after URL-to-PDF conversion

  • Date: 2026-03-02
  • Severity: MEDIUM
  • Issue: In src/services/browser.ts, renderUrlPdf() calls page.setRequestInterception(true) and adds a page.on("request", ...) listener for SSRF DNS pinning. recyclePage() never cleans these up. When the page is returned to the pool and reused, the stale interceptor blocks external resource requests (fonts, images, stylesheets) for subsequent HTML-to-PDF conversions. Successive URL-to-PDF calls on the same page also stack listeners.
  • Impact: After a URL-to-PDF conversion, any HTML-to-PDF conversion reusing the same page may fail to load external resources. Low probability in practice (depends on pool cycling) but a real data corruption vector.
  • Fix: Add page.removeAllListeners("request") and page.setRequestInterception(false) to recyclePage().
  • Status: ✅ FIXED — commit 024fa00. recyclePage now calls removeAllListeners("request") + setRequestInterception(false). 1 test added (TDD red→green verified). 443 tests total. Deployed to staging.

BUG-097: Footer "Support" link missing on /examples, /privacy, and /status pages

  • Date: 2026-03-02
  • Severity: LOW
  • Issue: The footer "Support" mailto link (support@docfast.dev) is present on /, /impressum, and /terms but MISSING from /examples, /privacy, and /status. Footer should be consistent across all pages.
  • Status: ✅ FIXED — commit 6290c3e. Added Support link to shared footer partial. Verified on staging.
  • Status: ✅ FIXED — commit 6290c3e. Added Support mailto link to _footer.html partial. 2 tests added. Verified on staging.

BUG-096: Demo endpoint accepts invalid scale value (scale:99) without returning 400 error

  • Date: 2026-03-02
  • Severity: MEDIUM
  • Issue: POST /v1/demo/html with {"html":"<h1>test</h1>","options":{"scale":99}} returns HTTP 200 and generates a PDF instead of returning a 400 validation error. Chromium's page.pdf() scale parameter accepts values between 0.1 and 2.0, so scale:99 is clearly invalid and should be rejected. The API silently accepts it, which could cause unexpected behavior (Chromium may clamp or error internally).
  • Steps to reproduce: curl -X POST https://staging.docfast.dev/v1/demo/html -H "Content-Type: application/json" -d '{"html":"<h1>test</h1>","options":{"scale":99}}' → returns PDF (200)
  • Expected: HTTP 400 with validation error about scale range
  • Actual: HTTP 200 with generated PDF
  • Note: format:"invalid" and margin with non-string values could not be retested due to 5/hour demo rate limit. These may also lack validation.

BUG-095: /docs page footer missing most footer links (Home, Docs, Examples, API Status, Support, Change Email)

  • Date: 2026-03-02
  • Severity: LOW
  • Issue: The /docs page (Swagger UI) footer only shows Impressum, Privacy Policy, and Terms of Service. Missing Home, Docs, Examples, API Status, Support, and Change Email links.
  • Status: ✅ FIXED — commit 6290c3e. Expanded docs.html footer to include all 9 links. Verified on staging.
  • Status: ✅ FIXED — commit 6290c3e. Expanded docs.html footer to include all 9 links. 2 tests added. Verified on staging.

BUG-092: Footer missing "Change Email" link on landing page

  • Date: 2026-03-01
  • Severity: LOW
  • Issue: The email change modal exists in the DOM but the footer has no link to trigger it. BUG-090 added the backend routes, but when the free tier was removed, the "Change Email" footer link was also removed (it was part of the old footer layout). Users have no way to reach the email change feature from the landing page.
  • Fix: Add "Change Email" link back to footer with class="open-email-change".
  • Status: ✅ FIXED — commit added Change Email link to both public/src/index.html footer and public/partials/_footer.html. 2 tests added verifying footer link presence. 438 tests total, all passing.

BUG-090: Email Change modal calls non-existent backend routes — feature broken

  • Date: 2026-02-27
  • Severity: HIGH
  • Issue: The "Change Email" modal on the landing page (and footer links on all pages) calls POST /v1/email-change and POST /v1/email-change/verify. These backend routes DO NOT EXIST. The frontend was built but the backend was never implemented. Users who try to change their email get a 404 "Not Found" error.
  • Impact: Complete user flow is broken. A feature advertised on every page doesn't work. Violates "every user flow must be complete" rule.
  • Fix: Implement src/routes/email-change.ts with both endpoints, following existing verification code pattern.
  • Status: ✅ FIXED — commit 480c794. Route + 9 tests added. 291 tests total, all passing. Awaiting CI build (runner appears down).

BUG-089: Examples page not linked from main navigation or footer

  • Date: 2026-02-27
  • Severity: MEDIUM
  • Issue: The /examples page exists and is in the sitemap, but is NOT linked from the main landing page nav or footer. The examples page itself includes "Examples" in its nav, but all other pages (/, /docs, /impressum, /privacy, /terms, /status) lack it. Developers can't discover code examples from the homepage.
  • Impact: High-value developer conversion page is hidden. Only discoverable via sitemap or direct URL.
  • Fix: Add "Examples" link to nav and footer partials so it appears on all pages.
  • Status: ✅ FIXED — commit aa7fe55. Added to landing page inline nav, landing page footer, and shared footer partial. Nav partial already had the link.

BUG-088: Landing page and FAQ schema falsely claim SDKs exist

  • Date: 2026-02-26
  • Severity: MEDIUM
  • Issue: FAQ structured data and landing page text both claim "Official SDKs for Node.js, Python, Go, PHP, and Laravel" exist. SDKs have NOT been published — only code examples exist. The /examples page was fixed (BUG-086) but landing page and FAQ schema were missed.
  • Impact: Misleading structured data could hurt SEO trust. Users expecting npm install docfast would be confused.
  • Fix: Updated FAQ answer and landing page subtitle to say "Code examples for Node.js, Python, Go, PHP, and cURL. Official SDKs coming soon."
  • Status: ✅ FIXED — commit 9dcc473

BUG-087: OpenAPI spec empty on staging — swagger-jsdoc 7.0.0-rc.6 regression

  • Date: 2026-02-25
  • Severity: HIGH
  • Issue: Session 93 upgraded swagger-jsdoc from 6.2.8 to 7.0.0-rc.6 to fix a minimatch ReDoS vuln. The RC is broken — swaggerJsdoc() returns {} (empty object, 0 paths). The /docs page on staging shows no API endpoints. /openapi.json returns {}.
  • Root cause: swagger-jsdoc 7.0.0-rc.6 does not parse @openapi JSDoc annotations from glob-matched files.
  • Impact: Staging has no API documentation. Production (v0.4.5) is unaffected (still on 6.2.8 build).
  • Fix: Reverted to swagger-jsdoc 6.2.8. Added 2 regression tests verifying OpenAPI spec has paths and includes key endpoints. npm audit still shows 0 vulnerabilities.
  • Status: ✅ FIXED — commit 288d6c7, deploying to staging

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.

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

  • "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

Summary

Test Result
Console errors ✅ PASS (0 errors)

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" ...>

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>: 
    <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

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).

BUG-085: Examples page uses non-existent api.docfast.dev subdomain

  • Date: 2026-02-23
  • Severity: HIGH
  • Issue: Node.js, Python, Go, PHP examples on /examples page reference https://api.docfast.dev/v1/convert/html and https://api.docfast.dev/v1/convert/markdown. The api.docfast.dev subdomain does not exist — correct URL is https://docfast.dev/v1/.... Developers following examples will get DNS errors.
  • Affected: staging.docfast.dev/examples (and production once deployed)
  • Fix: Replace all api.docfast.dev with docfast.dev in public/src/examples.html
  • Status: ✅ FIXED (commit 1c0c8a3) — all api.docfast.dev → docfast.dev

BUG-086: Examples page references non-existent SDK packages

  • Date: 2026-02-23
  • Severity: MEDIUM
  • Issue: Go example says go get github.com/docfast/docfast-go (404 on GitHub). PHP example says composer require docfast/docfast-php (doesn't exist on Packagist). SDKs haven't been published yet — blocked on npm/PyPI/Go/Packagist tokens.
  • Fix: Either publish SDKs or change examples to use plain HTTP (curl/fetch) without SDK install instructions until packages are published.
  • Status: ✅ FIXED (commit 1c0c8a3) — replaced with "SDK coming soon" notes, kept HTTP examples

BUG-091: Demo endpoint accepts invalid scale value (scale:99) without error

  • Date: 2026-03-01
  • Severity: MEDIUM
  • Issue: POST /v1/demo/html with {"html":"<h1>test</h1>","options":{"scale":99}} returns HTTP 200 and generates a PDF instead of returning 400 validation error. Chromium's valid scale range is 0.1–2.0. Scale of 99 should be rejected.
  • Steps to reproduce: curl -X POST https://staging.docfast.dev/v1/demo/html -H 'Content-Type: application/json' -d '{"html":"<h1>test</h1>","options":{"scale":99}}'
  • Expected: 400 error with validation message about invalid scale
  • Actual: 200 with a PDF generated (Chromium may silently clamp or ignore)
  • Status: ✅ FALSE POSITIVE — API uses top-level params, not nested options object. scale:99 at top level IS correctly validated. Confirmed session 117/118.

BUG-092: Footer missing "Change Email" link

  • Date: 2026-03-01
  • Severity: LOW
  • Issue: The task spec expects a "Change Email" link in the footer, but it's not present. The change email modal (emailChangeModal) exists in the DOM but there's no footer link to trigger it. Users have no discoverable way to access the email change feature from the landing page.
  • Steps to reproduce: Visit https://staging.docfast.dev/ → scroll to footer → no "Change Email" link
  • Expected: Footer should include a "Change Email" link
  • Actual: Footer has: Home, Docs, Examples, API Status, Support, Impressum, Privacy Policy, Terms of Service — no Change Email
  • Status: OPEN

BUG-093: Signup modal removed but "Get Pro API Key" button text is misleading

  • Date: 2026-03-01
  • Severity: LOW
  • Issue: Free signup was discontinued (API returns 410). The signup modal (signupModal) has been removed from the DOM. However, the "Get Pro API Key — €9/mo" button now redirects directly to Stripe checkout, which is correct behavior. Not a bug per se, but the old "signup modal" test case is no longer applicable — documenting for awareness.
  • Status: NOT A BUG — by design after free tier removal

BUG-094: email-change endpoint returns unhelpful error without auth

  • Date: 2026-03-01
  • Severity: LOW
  • Issue: POST /v1/email-change without authentication returns {"error":"apiKey is required."} with HTTP 400. Should return 401 for consistency with other auth-required endpoints (/v1/convert/html and /v1/usage return 401).
  • Steps to reproduce: curl -X POST https://staging.docfast.dev/v1/email-change -H 'Content-Type: application/json' -d '{"current_email":"a@b.com","new_email":"c@d.com"}'
  • Expected: 401 with consistent "Missing API key" error message
  • Actual: 400 with "apiKey is required."
  • Status: ✅ WON'T FIX — email-change uses body apiKey param (not header auth), so 400 for missing body field is correct. Different auth pattern from header-auth endpoints.
