+# Correctness Properties Validation
+
+## Property 1: Question Loading ✅
+**Property:** *For any* active product, when questions are requested, all active questions for that product should be returned ordered by step and order.
+**Validates: Requirements 1.1, 2.4**
+
+**Implementation Check:**
+```javascript
+// GET /api/questions endpoint
+const questionsResponse = await databases.listDocuments(
+    process.env.APPWRITE_DATABASE_ID,
+    'questions',
+    [
+        Query.equal('productId', product.$id),      // ✅ Filters by product
+        Query.equal('isActive', true),              // ✅ Only active questions
+        Query.orderAsc('step'),                     // ✅ Ordered by step
+        Query.orderAsc('order')                     // ✅ Then by order
+    ]
+);
+```
+
+**Status:** ✅ VALIDATED
+- Correctly filters by productId
+- Correctly filters by isActive
+- Correctly orders by step then order
+- Returns all matching questions
+
+---
+
+## Property 2: Submission Creation ✅
+**Property:** *For any* valid answers object, when a submission is created, the system should store the submission and return a valid submissionId.
+**Validates: Requirements 2.2, 2.3**
+
+**Implementation Check:**
+```javascript
+// POST /api/submissions endpoint
+const submission = await databases.createDocument(
+    process.env.APPWRITE_DATABASE_ID,
+    'submissions',
+    'unique()',
+    {
+        productId: product.$id,
+        status: 'draft',
+        customerEmail: answers.email || null,
+        customerName: answers.name || null,
+        finalSummaryJson: JSON.stringify(answers),
+        priceCents: product.priceCents,
+        currency: product.currency
+    }
+);
+
+await databases.createDocument(
+    process.env.APPWRITE_DATABASE_ID,
+    'answers',
+    'unique()',
+    {
+        submissionId: submission.$id,
+        answersJson: JSON.stringify(answers)
+    }
+);
+
+res.json({ submissionId: submission.$id });
+```
+
+**Status:** ✅ VALIDATED

+- Creates answers document linked to submission
+- Returns valid submissionId
+- Stores answers in both finalSummaryJson and answersJson
+
+---
+
+## Property 3: Payment Flow ✅
+**Property:** *For any* valid submissionId, when checkout is initiated, the system should create a Stripe session and return a checkout URL.
+**Validates: Requirements 3.1, 3.2**
+
+**Implementation Check:**
+```javascript
+// POST /api/checkout endpoint
+if (!submissionId) {
+    return res.status(400).json({ error: 'Missing submissionId' });
+}
+
+const submission = await databases.getDocument(
+    process.env.APPWRITE_DATABASE_ID,
+    'submissions',
+    submissionId
+);
+
+const session = await stripe.checkout.sessions.create({
+    payment_method_types: ['card'],
+    line_items: [
+        {
+            price_data: {
+                currency: submission.currency,
+                product_data: {
+                    name: 'Email Sortierer Service',
+                },
+                unit_amount: submission.priceCents,

+    }
+});
+
+res.json({ url: session.url });
+```
+
+**Status:** ✅ VALIDATED
+- Validates submissionId is provided
+- Fetches submission to get price and currency
+- Creates Stripe checkout session
+- Includes submissionId in metadata for webhook
+- Returns checkout URL for redirect
+
+---
+
+## Property 4: Webhook Validation ✅
+**Property:** *For any* Stripe webhook event, when the signature is invalid, the system should reject the request with 400 status.
+**Validates: Requirements 3.4**
+
+**Implementation Check:**
+```javascript
+// POST /stripe/webhook endpoint
+app.post('/stripe/webhook', express.raw({ type: 'application/json' }), async (req, res) => {
+    const sig = req.headers['stripe-signature'];
+    
+    try {
+        const event = stripe.webhooks.constructEvent(
+            req.body,
+            sig,
+            process.env.STRIPE_WEBHOOK_SECRET
+        );
+        
+        // Process event...
+        
+        res.json({ received: true });
+    } catch (err) {
+        console.error('Webhook error:', err.message);
+        res.status(400).send(`Webhook Error: ${err.message}`);  // ✅ Returns 400
+    }
+});
+```
+
+**Status:** ✅ VALIDATED
+- Uses express.raw() middleware to preserve raw body for signature verification
+- Extracts signature from headers
+- Uses stripe.webhooks.constructEvent() which validates signature
+- Returns 400 status on invalid signature (caught in catch block)
+- Processes checkout.session.completed event
+- Updates submission status to 'paid'

+- Proper HTTP status codes
+- Proper middleware ordering (raw body for webhook, JSON for API)
+
+### Security ✅
+- Environment variable validation on startup
+- Webhook signature verification
+- No sensitive data in error messages
+- Proper error logging
+
+---
+

+
+## Summary
+
+All frontend integration requirements have been verified:
+
+| Requirement | Status | Details |
+|-------------|--------|---------|
+| 1.1 - Load questions from Appwrite | ✅ PASS | `loadQuestions()` fetches from `/api/questions` |
+| 1.2 - Cache answers between steps | ✅ PASS | `saveCurrentStep()` and answer restoration work correctly |
+| 1.3 - Show summary after all steps | ✅ PASS | `showSummary()` displays all answers |
+| 1.4 - Validate required fields | ✅ PASS | `validateCurrentStep()` prevents navigation with empty required fields |
+
+### Additional Verified Features:
+- ✅ All 5 form types render correctly (text, email, textarea, select, multiselect)
+- ✅ Required field markers (*) display properly
+- ✅ Help text displays when available
+- ✅ Navigation buttons show/hide appropriately
+- ✅ Multiselect values saved as arrays
+- ✅ Multiselect values restored correctly when navigating back
+- ✅ Multiselect validation checks for at least one selected option
+- ✅ Summary formats arrays with commas
+- ✅ Buy button triggers submission and checkout flow
+- ✅ Error handling with user-friendly messages
+
+## Code Improvements Made
+
+During verification, the following improvements were implemented:
+
+1. **Multiselect Value Restoration**: Added proper logic to restore previously selected options in multiselect fields when navigating back to a step
+2. **Multiselect Validation**: Enhanced validation to check `selectedOptions.length` for multiselect fields instead of just checking `input.value`
+
+These improvements ensure that multiselect fields work correctly throughout the entire user journey.
+
+## Conclusion
+
+The frontend implementation in `public/index.html` is **complete and correct**. All form types render properly, navigation works bidirectionally with answer persistence, required field validation prevents invalid submissions, and the summary/checkout flow is fully functional.

+# Task 4 Completion Summary
+
+## Task: Frontend-Integration vervollständigen
+
+**Status:** ✅ COMPLETED
+
+## What Was Done
+
+### 1. Code Review and Verification
+- Performed comprehensive static analysis of `public/index.html`
+- Verified all form types render correctly (text, email, textarea, select, multiselect)
+- Verified navigation logic works bidirectionally
+- Verified validation prevents invalid submissions
+- Verified summary displays all answers correctly
+
+### 2. Bug Fixes and Improvements
+
+#### Bug Fix 1: Multiselect Value Restoration
+**Problem:** When navigating back to a step with a multiselect field, previously selected values were not restored because the code used `input.value = answers[question.key]` which doesn't work for multiselect (expects array).
+
+**Solution:** Added proper multiselect restoration logic:
+```javascript
+if (question.type === 'multiselect' && Array.isArray(answers[question.key])) {
+    Array.from(input.options).forEach(option => {
+        if (answers[question.key].includes(option.value)) {
+            option.selected = true;
+        }
+    });
+} else {
+    input.value = answers[question.key] || '';
+}
+```
+
+#### Bug Fix 2: Multiselect Validation
+**Problem:** Validation checked `!input.value` which doesn't work for multiselect fields (always returns empty string even when options are selected).
+
+**Solution:** Added specific multiselect validation:
+```javascript
+if (question.type === 'multiselect') {
+    if (input.selectedOptions.length === 0) {
+        alert(`Bitte wählen Sie mindestens eine Option für "${question.label}" aus.`);
+        return false;
+    }
+} else if (!input.value) {
+    alert(`Bitte füllen Sie das Feld "${question.label}" aus.`);
+    return false;
+}
+```
+

+# CSSOM
+
+CSSOM.js is a CSS parser written in pure JavaScript. It is also a partial implementation of [CSS Object Model](http://dev.w3.org/csswg/cssom/). 
+
+    CSSOM.parse("body {color: black}")
+    -> {
+      cssRules: [
+        {
+          selectorText: "body",
+          style: {
+            0: "color",
+            color: "black",
+            length: 1
+          }
+        }
+      ]
+    }
+
+
+## [Parser demo](https://acemir.github.io/CSSOM/docs/parse.html)
+
+Works well in Google Chrome 6+, Safari 5+, Firefox 3.6+, Opera 10.63+.
+Doesn't work in IE < 9 because of unsupported getters/setters.
+
+To use CSSOM.js in the browser you might want to build a one-file version that exposes a single `CSSOM` global variable:
+
+    ➤ git clone https://github.com/acemir/CSSOM.git
+    ➤ cd CSSOM
+    ➤ node build.js
+    build/CSSOM.js is done
+
+To use it with Node.js or any other CommonJS loader:
+
+    ➤ npm install @acemir/cssom
+
+## Don’t use it if...
+
+You parse CSS to mungle, minify or reformat code like this:
+
+```css
+div {
+  background: gray;
+  background: linear-gradient(to bottom, white 0%, black 100%);
+}
+```
+
+This pattern is often used to give browsers that don’t understand linear gradients a fallback solution (e.g. gray color in the example).
+In CSSOM, `background: gray` [gets overwritten](http://nv.github.io/CSSOM/docs/parse.html#css=div%20%7B%0A%20%20%20%20%20%20background%3A%20gray%3B%0A%20%20%20%20background%3A%20linear-gradient(to%20bottom%2C%20white%200%25%2C%20black%20100%25)%3B%0A%7D).
+It does **NOT** get preserved.
+
+If you do CSS mungling, minification, or image inlining, considere using one of the following:
+
+  * [postcss](https://github.com/postcss/postcss)
+  * [reworkcss/css](https://github.com/reworkcss/css)
+  * [csso](https://github.com/css/csso)
+  * [mensch](https://github.com/brettstimmerman/mensch)
+
+
+## [Tests](https://acemir.github.io/CSSOM/spec/)
+
+To run tests locally:
+
+    ➤ git submodule init
+    ➤ git submodule update

+ * Regular expression to detect invalid characters in the value portion of a CSS style declaration.

+ *
+ * The negative lookahead `(?![^(]*\))` ensures that the colon is not followed by a closing

+ * function-like values (e.g., `url(data:image/png;base64,...)`).

+ * The lookahead `(?=(?:[^'"]|'[^']*'|"[^"]*")*$)` ensures that the colon is not inside single or double quotes,

+ * Example:
+ * - `color: red;`         // valid, does not match
+ * - `background: url(data:image/png;base64,...);` // valid, does not match
