 # Security Assessment Report: MarkdownConverter v4.0.0
 **Assessment Date:** 2026-03-15
 **Application:** MarkdownConverter - Electron-based Markdown editor and document converter
 **Target Version:** 4.0.0
 **Assessor:** Security Audit Agent
 ---
 ## Executive Summary
 This assessment identified **10 security findings** ranging from **Critical to Low severity**. The most significant concerns involve insecure Electron security configuration that could allow XSS attacks to escalate to full system access, arbitrary code execution via the REPL feature, and missing input validation on file operations.
 | Severity | Count |
 |----------|-------|
 | Critical | 2 |
 | High | 3 |
 | Medium | 3 |
 | Low | 2 |
 ---
 ## Vulnerability Findings
 ### CVE-MC-001: Insecure Electron Security Configuration (Critical)
 **CVSS 3.1 Score: 9.6 (Critical)**
 **CWE-265: CWE-1021: Improper Restriction of Renderers**
 **Location:** `src/main.js` (lines 328-332)
 ```javascript
 webPreferences: {
  nodeIntegration: true,
  contextIsolation: false,
  spellcheck: true
 },
 ```
 **Description:**
 The main application window has `nodeIntegration: true` and `contextIsolation: false`, which is the most insecure Electron configuration. This allows the renderer process direct access to Node.js APIs, meaning any XSS vulnerability in the markdown rendering or external content could lead to full system compromise.
 **Exploitability:**
 - An attacker who can inject malicious JavaScript (via markdown files, XSS in preview, or compromised dependencies) gains immediate access to:
  - Full file system read/write via `fs` module
  - Command execution via `child_process`
  - Network access via `net` module
  - All system resources
 **Attack Scenario:**
 1. User opens a malicious markdown file containing embedded JavaScript
 2. The JavaScript executes in the renderer with full Node.js access
 3. Attacker can read sensitive files, execute commands, exfiltrate data
 **Remediation:**
 ```javascript
 webPreferences: {
  nodeIntegration: false,
  contextIsolation: true,
  sandbox: true,
  preload: path.join(__dirname, 'preload.js')
 }
 ```
 **Note:** The preload.js file already implements a secure IPC bridge but it is not being utilized for the main window.
 ---
 ### CVE-MC-002: Arbitrary Code Execution via REPL Feature (Critical)
 **CVSS 3.1 Score: 9.3 (Critical)**
 **CWE-94: Improper Control of Generation of Code ('Code Injection')**
 **Location:** `src/main.js` (lines 4369-4396)
 **Description:**
 The `execute-code` IPC handler allows execution of arbitrary Python and Bash scripts through the REPL panel. While JavaScript execution appears to have been removed or limited, Python and Bash commands are executed via `execFile` with user-supplied code.
 **Vulnerable Code Pattern:**
 ```javascript
 ipcMain.handle('execute-code', async (event, { code, language }) => {
  // ...
  if (language === 'python' || language === 'py') {
    cmd = 'python';
    args = ['-c', code];
  }
  // ...
  execFile(cmd, args, { timeout }, (err, stdout, stderr) => {
    // ...
  });
 });
 ```
 **Exploitability:**
 - Users can be tricked into running malicious code blocks
 - Markdown files can contain executable code blocks with "Run" buttons
 - No sandboxing or permission restrictions on executed code
 **Attack Scenario:**
 1. Attacker creates markdown file with malicious Python code block
 2. User clicks "Run" button in preview
 3. Python code executes with user's full permissions
 4. Attacker gains code execution on victim's machine
 **Remediation:**
 - Remove arbitrary code execution feature entirely, OR
 - Implement strict sandboxing (Docker, VM, or restricted Python environment)
 - Add user confirmation dialogs with clear warnings
 - Execute in isolated environment with no filesystem/network access
 - Implement allowlist of safe operations
 ---
 ### CVE-MC-003: Potential XSS in Markdown Rendering (High)
 **CVSS 3.1 Score: 8.0 (High)**
 **CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')**
 **Location:** `src/renderer.js` (lines 387-419)
 **Description:**
 While DOMPurify is used to sanitize HTML, several extensions to marked.js may bypass sanitization:
 1. **Custom Admonition Extension (lines 51-77):**
 ```javascript
 marked.use({
    extensions: [{
        name: 'admonition',
        // ...
        renderer(token) {
            const inner = this.parser.parse(token.text);
            return `<div class="admonition admonition-${token.admonitionType}">
                <div class="admonition-title">${icon} ${token.admonitionType...}</div>
                <div class="admonition-content">${inner}</div>
            </div>`;
        }
    }]
 });
 ```
 2. **innerHTML Assignments (line 419):**
 ```javascript
 preview.innerHTML = sanitizedHtml;
 ```
 **Exploitability:**
 - Combined with CVE-MC-001, XSS leads to full system compromise
 - Custom markdown extensions may not be properly sanitized
 - Admonition type is directly interpolated into HTML without escaping
 **Remediation:**
 - Ensure all custom markdown extensions escape user input
 - Add Content Security Policy that blocks inline scripts
 - Use `textContent` instead of `innerHTML` where possible
 - Audit all custom marked.js extensions for XSS vectors
 ---
 ### CVE-MC-004: Missing Path Traversal Protection (High)
 **CVSS 3.1 Score: 7.8 (High)**
 **CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')**
 **Location:** `src/main.js` (lines 4241-4281)
 **Description:**
 The `list-directory` and `open-file-path` IPC handlers accept arbitrary file paths without validation:
 ```javascript
 ipcMain.handle('list-directory', async (event, dirPath) => {
  try {
    if (!dirPath) { /* dialog */ }
    // No path validation - accepts any path
    const entries = fs.readdirSync(dirPath, { withFileTypes: true });
    // ...
  }
 });
 ipcMain.on('open-file-path', (event, filePath) => {
  // No path validation
  if (!fs.existsSync(filePath)) return;
  const content = fs.readFileSync(filePath, 'utf-8');
  mainWindow.webContents.send('file-opened', { path: filePath, content });
 });
 ```
 **Exploitability:**
 - Malicious renderer code can read any file on the system
 - No restriction to a sandbox directory
 - Combined with XSS, attacker can exfiltrate sensitive files
 **Remediation:**
 ```javascript
 const ALLOWED_DIRECTORIES = [app.getPath('documents'), app.getPath('desktop')];
 function isPathAllowed(filePath) {
  const resolved = path.resolve(filePath);
  return ALLOWED_DIRECTORIES.some(dir => resolved.startsWith(dir));
 }
 ```
 ---
 ### CVE-MC-005: Weak Content Security Policy (High)
 **CVSS 3.1 Score: 7.5 (High)**
 **CWE-1021: Improper Restriction of Renderers**
 **Location:** `src/index.html` (line 5)
 ```html
 <meta http-equiv="Content-Security-Policy" content="default-src 'self';
  script-src 'self' 'unsafe-inline' 'unsafe-eval' https://cdn.jsdelivr.net;
  style-src 'self' 'unsafe-inline' https://cdnjs.cloudflare.com;
  img-src 'self' data: blob: file:;
  font-src 'self' data:;
  connect-src 'self' https://www.plantuml.com;">
 ```
 **Description:**
 The CSP contains several security weaknesses:
 1. **`'unsafe-inline'` in script-src** - Allows inline script injection
 2. **`'unsafe-eval'` in script-src** - Allows `eval()` and similar functions
 3. **`https://cdn.jsdelivr.net`** - Allows scripts from external CDN (supply chain risk)
 4. **`file:` in img-src** - Allows loading local files as images (potential information disclosure)
 **Exploitability:**
 - XSS attacks can execute arbitrary scripts
 - External CDN compromise could inject malicious code
 - `eval()` enables dynamic code execution
 **Remediation:**
 - Remove `'unsafe-inline'` and `'unsafe-eval'`
 - Use nonces or hashes for inline scripts
 - Remove external CDNs or use Subresource Integrity (SRI)
 - Remove `file:` from img-src
 ---
 ### CVE-MC-006: Insecure Window Configuration for PDF Export (Medium)
 **CVSS 3.1 Score: 6.5 (Medium)**
 **CWE-1021: Improper Restriction of Renderers**
 **Location:** `src/main.js` (lines 2579-2585)
 ```javascript
 const pdfWindow = new BrowserWindow({
  show: false,
  webPreferences: {
    nodeIntegration: true,
    contextIsolation: false
  }
 });
 ```
 **Description:**
 Hidden windows created for PDF export also have insecure configurations, allowing potential privilege escalation.
 **Remediation:**
 ```javascript
 webPreferences: {
  nodeIntegration: false,
  contextIsolation: true,
  sandbox: true
 }
 ```
 ---
 ### CVE-MC-007: PlantUML Server Data Exfiltration (Medium)
 **CVSS 3.1 Score: 5.3 (Medium)**
 **CWE-359: Exposure of Private Information**
 **Location:** `src/renderer.js` (lines 470-487)
 ```javascript
 const plantumlBlocks = preview.querySelectorAll('pre code.language-plantuml');
 plantumlBlocks.forEach((block) => {
    const code = block.textContent;
    // ...
    const encoded = plantumlEncode(code);
    const img = document.createElement('img');
    img.src = `https://www.plantuml.com/plantuml/svg/${encoded}`;
    // ...
 });
 ```
 **Description:**
 PlantUML diagram content is sent to an external server (plantuml.com) for rendering. This could leak sensitive information contained in diagrams.
 **Exploitability:**
 - Diagrams containing proprietary information, system architecture, or internal processes are sent to third-party servers
 - No user consent or notification before external data transmission
 **Remediation:**
 - Use local PlantUML rendering with Java
 - Add user warning before sending data to external service
 - Implement opt-in for external rendering
 ---
 ### CVE-MC-008: Inconsistent Security Settings Across Windows (Medium)
 **CVSS 3.1 Score: 5.5 (Medium)**
 **CWE-1021: Improper Restriction of Renderers**
 **Description:**
 Security settings are inconsistent across different windows:
 | Window | nodeIntegration | contextIsolation | Security |
 |--------|-----------------|------------------|----------|
 | Main Window | true | false | Insecure |
 | About Dialog | false | true | Secure |
 | Dependencies Dialog | false | true | Secure |
 | ASCII Generator | false | true | Secure |
 | Table Generator | false | true | Secure |
 | PDF Export Window | true | false | Insecure |
 | Hidden Conversion Window | true | false | Insecure |
 **Remediation:**
 Apply secure configuration (`nodeIntegration: false`, `contextIsolation: true`) consistently across all windows.
 ---
 ### CVE-MC-009: Command Execution via External Tools (Low)
 **CVSS 3.1 Score: 4.4 (Low)**
 **CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')**
 **Location:** `src/main.js` (lines 1915-1972)
 **Description:**
 While the application uses `execFile` instead of `exec` (good practice), external tools (Pandoc, LibreOffice, FFmpeg, ImageMagick) are invoked with file paths that could potentially be manipulated.
 **Positive Finding:**
 The code correctly uses `execFile` with argument arrays instead of shell commands, mitigating most command injection vectors.
 **Remaining Risk:**
 - File paths are not validated against malicious names
 - Special characters in filenames could cause issues with external tools
 **Remediation:**
 - Validate file paths before passing to external tools
 - Sanitize filenames of special characters
 ---
 ### CVE-MC-010: Missing Dependency Version Pinning (Low)
 **CVSS 3.1 Score: 3.5 (Low)**
 **CWE-1035: Using Components with Known Vulnerabilities**
 **Location:** `package.json`
 **Description:**
 Dependencies use `^` version ranges which could allow automatic updates to versions with vulnerabilities:
 ```json
 "dependencies": {
  "marked": "^17.0.3",
  "dompurify": "^3.3.1",
  "mermaid": "^11.12.3",
  // ...
 }
 ```
 **Remediation:**
 - Pin exact versions in production
 - Use lockfile (package-lock.json)
 - Implement dependency scanning in CI/CD pipeline

 ## Positive Security Findings
 1. **Preload.js Implementation:** A secure IPC bridge with channel whitelisting is implemented
 2. **DOMPurify Usage:** HTML sanitization is applied to markdown output
 3. **execFile Usage:** External commands use `execFile` instead of `exec`
 4. **File Size Limits:** 50MB maximum file size is enforced
 5. **Rate Limiting:** Conversion operations have rate limiting (2 second minimum interval)
 6. **Error Message Sanitization:** Absolute paths are stripped from error messages
 ---
 ## Prioritized Remediation Roadmap
 ### Phase 1 - Critical (Immediate)
 1. Set `nodeIntegration: false` and `contextIsolation: true` for main window
 2. Remove or sandbox the code execution (REPL) feature
 3. Implement proper preload.js usage for all windows
 ### Phase 2 - High Priority (1-2 Weeks)
 4. Add path traversal protection to file operations
 5. Strengthen Content Security Policy
 6. Audit and fix custom markdown extensions for XSS
 ### Phase 3 - Medium Priority (1 Month)
 7. Implement consistent security settings across all windows
 8. Add local PlantUML rendering option
 9. Implement dependency scanning in CI/CD
 ### Phase 4 - Low Priority (Ongoing)
 10. Pin dependency versions
 11. Add security headers to all generated HTML
 12. Implement security logging and monitoring

 ## Compliance Considerations
 - **OWASP Top 10 2021:** A03:2021 - Injection, A05:2021 - Security Misconfiguration
 - **OWASP ASVS:** V12 - File Handling, V13 - API Security
 - **NIST CSF:** PR.AC - Access Control, PR.DS - Data Security
 ---
 ## Conclusion
 The MarkdownConverter application has significant security vulnerabilities that could allow an attacker to execute arbitrary code, access sensitive files, and compromise the user's system. The most critical issue is the insecure Electron configuration combined with XSS attack vectors in the markdown rendering pipeline.
 **Overall Security Rating: HIGH RISK**
 The positive finding is that much of the security infrastructure (preload.js, DOMPurify) is already in place but not properly utilized. With focused remediation effort, the application can achieve a much stronger security posture.

 # Comprehensive UI Design Review - MarkdownConverter Electron Application
 ## Executive Summary
 This review covers the UI design of the MarkdownConverter Electron application, analyzing visual design, usability, code quality, and performance across all UI files. The application has a solid foundation but has several areas requiring attention.
 ---
 ## 1. Visual Design Review
 ### 1.1 Spacing & Layout Consistency
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Inconsistent padding values across files | Multiple CSS files | Standardize to 4px/8px base scale |
 | **Major** | Multiple reset declarations | `styles.css:1-5`, `styles-modern.css:42-47` | Consolidate resets into single file |
 | **Minor** | Tab padding varies between themes | `styles.css:36`, `styles-modern.css:101` | Use CSS variables for consistent padding |
 | **Minor** | Container padding inconsistency | `styles.css:17-21`, `styles-modern.css:63-69` | Define single container style |
 **Code Example - Duplicate Reset:**
 ```css
 /* styles.css:1-5 */
 * {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
 }
 /* styles-modern.css:42-47 - DUPLICATE */
 * {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
 }
 ```
 **Fix Recommendation:**
 ```css
 /* Create a single base.css or remove from styles-modern.css */
 /* Use CSS variables for spacing scale */
 :root {
  --space-1: 4px;
  --space-2: 8px;
  --space-3: 12px;
  --space-4: 16px;
  --space-5: 24px;
  --space-6: 32px;
 }
 ```
 ### 1.2 Typography Consistency
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Font-family declared multiple times with different fallbacks | `styles.css:8`, `styles-modern.css:50`, `styles-concreteinfo.css:32` | Standardize font stack |
 | **Major** | Duplicate font-size declarations | `styles.css:228-230` | Remove duplicate |
 | **Minor** | Inconsistent line-height values | Multiple files | Create type scale variables |
 **Code Example - Duplicate font-size:**
 ```css
 /* styles.css:226-230 */
 .preview-content {
    max-width: none;
    margin: 0;
    padding: 20px 24px 24px 24px;
    line-height: 1.6;
    font-size: 15px;
    font-size: 14px;  /* DUPLICATE - overwrites previous */
 }
 ```
 **Fix Recommendation:**
 ```css
 /* styles.css - Remove duplicate */
 .preview-content {
    font-size: 14px;  /* Keep only one */
    line-height: 1.6;
 }
 ```
 ### 1.3 Color Usage and Contrast Accessibility
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Critical** | Hardcoded colors instead of CSS variables | `styles.css:27-29`, `styles.css:37-38`, etc. | Use CSS custom properties |
 | **Major** | Inconsistent gray scale definitions | Multiple files define different grays | Consolidate to single palette |
 | **Minor** | Some contrast ratios may be insufficient | Status bar text colors | Verify WCAG 2.1 AA compliance |
 **Code Example - Hardcoded colors:**
 ```css
 /* styles.css:27-29 */
 .tab-bar {
    background: #f0f0f0;  /* Should use var(--gray-100) */
    border-bottom: 1px solid #ddd;  /* Should use var(--gray-300) */
 }
 ```
 **Fix Recommendation:**
 ```css
 /* Use the existing palette from styles-modern.css */
 .tab-bar {
    background: var(--gray-100, #f3f4f6);
    border-bottom: 1px solid var(--gray-300, #d1d5db);
 }
 ```
 ### 1.4 Dark Mode Support Quality
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Dark theme selectors inconsistent | `styles.css` uses `body.theme-dark`, `styles-sidebar.css:108` uses `body[class*="dark"]` | Standardize selector pattern |
 | **Minor** | Missing dark theme support for some components | `.breadcrumb-bar`, command palette | Add dark mode variants |
 | **Suggestion** | Repetitive dark theme declarations | `styles-concreteinfo.css:362-425` | Use CSS custom properties for theming |
 **Code Example - Inconsistent selectors:**
 ```css
 /* styles.css */
 body.theme-dark .tab-bar { ... }
 /* styles-sidebar.css */
 body[class*="dark"] .sidebar-icons { ... }
 ```
 **Fix Recommendation:**
 ```css
 /* Choose one pattern and apply consistently */
 /* Option 1: Class-based (recommended) */
 body.theme-dark .tab-bar,
 body.theme-dark .sidebar-icons { ... }
 /* Option 2: Attribute-based */
 body[data-theme="dark"] .tab-bar { ... }
 ```
 ---
 ## 2. Usability Review
 ### 2.1 Clickable/Tappable Areas
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Critical** | Tab close button too small (16x16px) | `styles.css:62-77` | Increase to minimum 24x24px |
 | **Major** | Sidebar icons at minimum size | `styles-sidebar.css:35-47` (36x36px) | Consider 40-44px for better touch |
 | **Minor** | Toolbar buttons at edge of minimum | `styles.css:120-131` (32x32px) | Acceptable for mouse, small for touch |
 **Code Example - Small close button:**
 ```css
 /* styles.css:62-77 */
 .tab-close {
    width: 16px;   /* TOO SMALL - below 24px minimum */
    height: 16px;  /* TOO SMALL */
 }
 ```
 **Fix Recommendation:**
 ```css
 .tab-close {
    width: 24px;
    height: 24px;
    border-radius: 4px;
 }
 /* Add touch-friendly hit area */
 .tab-close::before {
    content: '';
    position: absolute;
    top: -4px;
    left: -4px;
    right: -4px;
    bottom: -4px;
 }
 ```
 ### 2.2 Hover/Focus States
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Critical** | Missing focus-visible styles | All interactive elements | Add :focus-visible for keyboard navigation |
 | **Major** | No focus indicators on toolbar buttons | `styles.css:133-140` | Add visible focus ring |
 | **Minor** | Inconsistent hover transitions | Various components | Standardize transition duration |
 **Code Example - Missing focus styles:**
 ```css
 /* styles.css:120-131 - No focus state */
 .toolbar button {
    /* ... no focus style */
 }
 .toolbar button:hover {
    background: #e0e0e0;
    border-color: #ccc;
 }
 ```
 **Fix Recommendation:**
 ```css
 .toolbar button:focus-visible {
    outline: 2px solid var(--primary-dark, #5661b3);
    outline-offset: 2px;
 }
 .toolbar button:hover {
    background: #e0e0e0;
    border-color: #ccc;
 }
 ```
 ### 2.3 Loading and Error State Handling
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Generic error message without styling | `renderer.js:384-386`, `renderer.js:508-511` | Create styled error components |
 | **Minor** | No loading indicators for async operations | Sidebar panels | Add skeleton loaders or spinners |
 | **Minor** | `git-loading` class exists but minimal styling | `styles-sidebar.css:227` | Enhance with animation |
 **Code Example - Plain error display:**
 ```javascript
 // renderer.js:384-386
 preview.innerHTML = '<p style="color: red; padding: 20px;">Error: Required libraries...';
 // Inline styles should be in CSS
 ```
 **Fix Recommendation:**
 ```css
 /* Add to styles.css */
 .preview-error {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    padding: 40px 20px;
    color: var(--ci-danger, #dc3545);
    text-align: center;
 }
 .preview-error-icon {
    font-size: 48px;
    margin-bottom: 16px;
 }
 ```
 ### 2.4 Accessibility (ARIA, Semantic HTML)
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Critical** | Buttons without accessible labels | `index.html:31` (tab close), `index.html:33` (new tab) | Add aria-label |
 | **Critical** | SVG icons lack aria-hidden | All toolbar buttons | Add aria-hidden="true" |
 | **Major** | Missing role attributes on tabs | `index.html:29-33` | Add role="tablist", role="tab" |
 | **Major** | No skip links | `index.html` | Add skip to main content link |
 | **Minor** | Dialog missing aria-modal | Export dialogs | Add aria-modal="true" |
 **Code Example - Missing accessibility attributes:**
 ```html
 <!-- index.html:31 - Current -->
 <button class="tab-close" title="Close tab">x</button>
 <!-- index.html:33 - Current -->
 <button class="new-tab-button" id="new-tab-btn" title="New tab">+</button>
 ```
 **Fix Recommendation:**
 ```html
 <!-- Improved with ARIA -->
 <div class="tab-bar" id="tab-bar" role="tablist" aria-label="Document tabs">
    <div class="tab active" data-tab-id="1" role="tab" aria-selected="true" aria-controls="tab-content-1">
        <span class="tab-title">Untitled</span>
        <button class="tab-close" aria-label="Close tab" title="Close tab">×</button>
    </div>
    <button class="new-tab-button" id="new-tab-btn" aria-label="Create new tab" title="New tab">+</button>
 </div>
 <!-- SVG icons should have aria-hidden -->
 <button id="btn-bold" title="Bold (Ctrl+B)" aria-label="Bold">
    <svg width="16" height="16" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" aria-hidden="true">
        ...
    </svg>
 </button>
 ```
 ### 2.5 Keyboard Navigation
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Tab order may skip sidebar icons | Sidebar panel | Verify logical tab order |
 | **Minor** | No escape key handling for dialogs | Export dialogs | Add escape to close |
 | **Minor** | Find dialog lacks full keyboard support | `renderer.js:804-866` | Add Ctrl+F shortcut hint |
 ---
 ## 3. Code Quality Review
 ### 3.1 CSS Organization & Naming
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | No clear CSS architecture | All CSS files | Adopt BEM or similar methodology |
 | **Major** | Overly generic class names | `.pane`, `.tab`, `.container` | Use more specific naming |
 | **Minor** | Mixed naming conventions | camelCase (`tabBar`), kebab-case (`tab-bar`) | Standardize to kebab-case |
 | **Minor** | Magic numbers | Various pixel values | Replace with spacing variables |
 ### 3.2 CSS Specificity Issues
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Excessive use of `!important` | `styles.css:14` | Restructure to avoid |
 | **Major** | Deep selector nesting | Dark theme selectors | Flatten and use CSS variables |
 | **Minor** | ID selectors for styling | `styles.css:233-247` | Prefer class selectors |
 **Code Example - Problematic specificity:**
 ```css
 /* styles.css:14 - Avoid !important */
 .hidden {
    display: none !important;
 }
 /* styles.css:397-431 - Deep nesting */
 body.theme-dark #preview h1,
 body.theme-dark [id^="preview-"] h1,
 body.theme-dark .preview-content h1 {
    color: #c9d1d9;
    border-bottom-color: #21262d;
 }
 ```
 **Fix Recommendation:**
 ```css
 /* Use utility class pattern */
 [hidden] { display: none; }
 /* Use CSS custom properties for theming */
 .preview-content h1 {
    color: var(--text-primary);
    border-bottom-color: var(--border-color);
 }
 /* Theme applies variables */
 body.theme-dark {
    --text-primary: #c9d1d9;
    --border-color: #21262d;
 }
 ```
 ### 3.3 Reusable Style Definitions
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Repeated button styles | Multiple files | Create button component classes |
 | **Major** | Dialog styles duplicated | Export, batch, print preview dialogs | Create modal component |
 | **Minor** | Similar form field styles scattered | Export dialog inputs | Create form component |
 **Code Example - Duplicated button styles:**
 ```css
 /* styles.css */
 .toolbar button { /* button styles */ }
 .tab-close { /* button styles */ }
 .new-tab-button { /* button styles */ }
 #export-dialog-close { /* button styles */ }
 /* styles-sidebar.css */
 .sidebar-icon { /* similar button styles */ }
 .sidebar-panel-close { /* similar button styles */ }
 ```
 **Fix Recommendation:**
 ```css
 /* Create button component system */
 .btn {
    display: inline-flex;
    align-items: center;
    justify-content: center;
    border: none;
    cursor: pointer;
    transition: all var(--transition-fast);
 }
 .btn--icon {
    width: 32px;
    height: 32px;
    border-radius: var(--radius-md);
 }
 .btn--close {
    font-size: 14px;
    font-weight: bold;
    border-radius: var(--radius-sm);
 }
 ```
 ### 3.4 Documentation
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Minor** | Limited CSS documentation | All CSS files | Add section comments |
 | **Minor** | No component documentation | Sidebar components | Add JSDoc-style comments |
 | **Suggestion** | No design tokens documentation | CSS variables | Create tokens documentation |
 ---
 ## 4. Performance Review
 ### 4.1 CSS Optimization
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | Large CSS files (105KB main, 78KB modern) | `styles.css`, `styles-modern.css` | Split into smaller modules |
 | **Major** | Duplicate style definitions | Multiple files | Remove redundancies |
 | **Minor** | Unused styles likely present | Theme variations | Audit and remove unused |
 ### 4.2 Asset Loading
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Major** | highlight.js CSS loaded synchronously | `index.html:14` | Load asynchronously or bundle |
 | **Minor** | Font files could be preloaded | `fonts.css` | Add preload links in HTML |
 | **Suggestion** | Consider CSS critical path | Above-the-fold styles | Inline critical CSS |
 **Code Example - Sync stylesheet loading:**
 ```html
 <!-- index.html:14 - Blocks rendering -->
 <link rel="stylesheet" href="../node_modules/highlight.js/styles/default.css">
 ```
 **Fix Recommendation:**
 ```html
 <!-- Non-blocking load -->
 <link rel="stylesheet" href="../node_modules/highlight.js/styles/default.css" media="print" onload="this.media='all'">
 <!-- Or preload fonts -->
 <link rel="preload" href="../assets/fonts/Inter-Regular.woff2" as="font" type="font/woff2" crossorigin>
 ```
 ### 4.3 Animation Performance
 | Severity | Issue | Location | Recommendation |
 |----------|-------|----------|----------------|
 | **Minor** | Some transitions on expensive properties | `styles-modern.css:111-112` | Prefer transform/opacity |
 | **Suggestion** | Missing will-change hints | Complex animations | Add will-change for GPU hints |
 ---
 ## 5. Component-Specific Issues
 ### 5.1 Tab System
 | File | Issues |
 |------|--------|
 | `styles.css:23-97` | Inconsistent active state styling, small close button |
 | `renderer.js:88-346` | Tab content created via innerHTML (XSS risk) |
 ### 5.2 Sidebar
 | File | Issues |
 |------|--------|
 | `styles-sidebar.css` | Good structure but missing focus states |
 | `sidebar-manager.js` | Clean implementation, needs ARIA |
 ### 5.3 Export Dialogs
 | File | Issues |
 |------|--------|
 | `styles.css:1060-1355` | Monolithic, should be component |
 | `index.html:171-331` | Complex nested structure needs semantic HTML |
 ### 5.4 Welcome Screen
 | File | Issues |
 |------|--------|
 | `styles-welcome.css` | Minimal styles, good foundation |
 | Missing hover states for keyboard focus | Add :focus-visible |
 ---
 ## 6. Prioritized Fix Recommendations
 ### Critical (Immediate)
 1. **Add missing ARIA attributes** to all interactive elements
 2. **Increase tab close button size** to minimum 24x24px
 3. **Add focus-visible styles** for keyboard navigation
 4. **Fix duplicate font-size declaration** in `.preview-content`
 ### Major (Next Sprint)
 1. **Consolidate CSS resets** into single location
 2. **Create button component system** with variants
 3. **Standardize dark theme selectors** across all files
 4. **Replace hardcoded colors** with CSS variables
 5. **Create modal/dialog component** to reduce duplication
 ### Minor (Future)
 1. **Document CSS architecture** and naming conventions
 2. **Audit and remove unused styles**
 3. **Add loading state components** (skeletons, spinners)
 4. **Implement CSS module splitting** for better performance
 ---
 ## 7. Summary Statistics
 | Category | Critical | Major | Minor | Suggestions |
 |----------|----------|-------|-------|-------------|
 | Visual Design | 1 | 5 | 4 | 1 |
 | Usability | 3 | 4 | 4 | 0 |
 | Code Quality | 0 | 6 | 4 | 1 |
 | Performance | 0 | 3 | 2 | 2 |
 | **Total** | **4** | **18** | **14** | **4** |
 ---
 ## Conclusion
 The MarkdownConverter application has a functional UI with good visual variety through its theme system. However, there are significant opportunities for improvement in:
 1. **Accessibility** - Critical for users with disabilities
 2. **Code organization** - Reduce CSS duplication and improve maintainability
 3. **Component consistency** - Standardize interactive element sizing and states
 4. **Performance** - Optimize CSS loading and reduce bundle size
 Addressing the Critical and Major issues will significantly improve both user experience and code maintainability.

 # Repository Guidelines
 ## Project Structure & Module Organization
 Core application code lives in `src/`. Use `src/main.js` for the Electron main process, `src/preload.js` for the preload bridge, and `src/renderer.js` plus `src/editor/`, `src/sidebar/`, `src/repl/`, and `src/utils/` for renderer-side features. Electron adapter code is in `src/adapters/electron/`. Reusable markdown/document templates live in `src/templates/`. Static assets and icons are in `assets/`. Tests are in `tests/`, and build output goes to `dist/`.
 ## Build, Test, and Development Commands
 - `npm start`: launch the Electron app locally.
 - `npm test`: run the Jest suite once.
 - `npm run test:watch`: rerun tests during local development.
 - `npm run test:coverage`: generate coverage output.
 - `npm run lint` / `npm run lint:fix`: check or fix ESLint issues in `src` and `tests`.
 - `npm run format` / `npm run format:check`: apply or verify Prettier formatting.
 - `npm run build:linux`, `npm run build:win`, `npm run build:mac`: create platform packages with `electron-builder`.
 ## Coding Style & Naming Conventions
 This repo uses Prettier and ESLint. Follow `.prettierrc`: 2-space indentation, single quotes, semicolons, trailing commas where valid in ES5, and a 100-character line width. Prefer `camelCase` for variables/functions, `PascalCase` for classes, and kebab-case for file names only when already established. Keep module boundaries clear: UI logic in renderer modules, OS/file-system work behind Electron IPC and adapters.
 ## Testing Guidelines
 Tests use Jest with `jest-environment-jsdom`. Add new tests under `tests/` with `*.test.js` names, mirroring the feature area when possible, for example `tests/sidebar.test.js` or `tests/print-preview.test.js`. Update or add regression tests for renderer behavior, preload APIs, and utility helpers when fixing bugs. Run `npm test` before opening a PR; use `npm run test:coverage` for larger refactors.
 ## Commit & Pull Request Guidelines
 Recent history follows Conventional Commit prefixes such as `feat:`, `fix:`, and `refactor:`. Keep subjects short and imperative, for example `fix: guard modal cleanup on close`. PRs should describe the user-visible change, note test coverage, link any related issue, and include screenshots or GIFs for UI changes.
 ## Security & Configuration Tips
 Do not bypass preload boundaries or introduce direct `eval`/dynamic code paths; ESLint already treats these as errors. Export and conversion features depend on external tools such as Pandoc, FFmpeg, ImageMagick, and LibreOffice, so document any new runtime dependency in `README.md` and packaging config.

-# CLAUDE.md — MarkdownConverter (master)
+# PanConverter - Claude Development Guide
 > General code-quality, JavaScript, git, security, and testing standards are in the **global CLAUDE.md**. This file holds project- and branch-specific notes.
 ## Project Overview
-Electron desktop app for Markdown editing and universal file conversion powered by Pandoc. Cross-platform (Win/macOS/Linux). Features: multi-tab editor with live preview, 25+ themes, PDF viewer/editor (merge/split/compress/rotate/watermark/password), export to 20+ formats (PDF/DOCX/ODT/EPUB/HTML/LaTeX/RTF/PPTX), batch conversion, syntax highlighting, diagram support (Mermaid), Git integration, and a plugin system.
+**PanConverter** is a cross-platform Markdown editor and converter powered by Pandoc, built with Electron. It provides professional-grade editing capabilities with comprehensive export options.
- **Version:** 4.4.5
+**Current Version**: v1.7.1
- **License:** MIT
+**Author**: Amit Haridas (amit.wh@gmail.com)
- **App ID:** `com.concreteinfo.markdownconverter`
+**License**: MIT
 **Repository**: https://github.com/amitwh/pan-converter
-## Branch Specifics
+## Architecture & Technology Stack
-This is the **primary/release branch** — a vanilla JavaScript Electron app with no bundler or framework in the renderer. The renderer is a single large `renderer.js` (5,300+ lines) loaded directly via `src/index.html`. All UI is hand-rolled DOM manipulation.
+### Core Technologies
 - **Electron** - Cross-platform desktop application framework
 - **Pandoc** - Universal document converter (required system dependency)
 - **ConvertAPI** - Cloud-based file conversion (200+ formats)
 - **marked** - Markdown parsing and rendering
 - **highlight.js** - Syntax highlighting
 - **KaTeX** - Mathematical expression rendering
 - **DOMPurify** - HTML sanitization
-## Architecture
+### Application Structure
 ```
 src/
 ├── main.js            # Electron main process, menu system, IPC handlers
 ├── renderer.js        # TabManager class, multi-file editing, event handling
 ├── index.html         # Application layout with tabbed interface
 ├── styles.css         # Base styling with multi-theme support
 └── styles-modern.css  # Modern glassmorphism UI design system (v1.7.1)
-### Main Process (`src/main.js` — 4,260 lines)
+assets/
-Monolithic main process file. Contains all IPC handlers, Pandoc invocation, file operations, menu definitions (600+ lines), and window lifecycle. Key modules extracted:
+└── icon.png       # Application icon
 - `src/main/PDFOperations.js` — PDF manipulation via `pdf-lib` (merge, split, compress, rotate, delete, reorder, watermark, encrypt, decrypt, permissions)
 - `src/main/GitOperations.js` — Git status/stage/commit/log via `simple-git`
-### Renderer (`src/renderer.js` — 5,361 lines)
+package.json       # Dependencies and build configuration
-Vanilla JS, no framework. Directly manipulates DOM. Loads CodeMirror 6 via `src/editor/codemirror-setup.js`. Uses `marked` + `highlight.js` + `DOMPurify` + `mermaid` for rendering. Lazy-loads sidebar panels, REPL, command palette, zen mode.
+CLAUDE.md          # Development documentation for AI assistants
-
+```
 ### Preload (`src/preload.js` — 448 lines)
 Exists as IPC bridge, but **`contextIsolation: false` and `nodeIntegration: true`** — the renderer has full Node access. Preload is effectively a thin passthrough.
 ### Security Model
 - `contextIsolation: false` + `nodeIntegration: true` (legacy; the react-electron branch fixes this)
 - Pandoc invoked via `execFile` (not `exec`) to prevent shell injection
 - Path traversal protection: `validatePath()`, `resolveWritablePath()`, blocks sensitive system dirs
 - Permission handler only allows `clipboard-read`/`clipboard-write`
 - Rate limiter on conversions (2-second minimum interval)
 - File size limit: 50MB
 - Error message sanitization strips absolute paths
 ### Plugin System (`src/plugins/`)
 Manifest-based discovery (`manifest.json`). Built-in `writing-studio` plugin with sprint/goal/snapshot management. Plugin API exposed via `src/plugins/plugin-api.js`.
 ### Settings
 Custom JSON file store at `<userData>/settings.json` (NOT `electron-store` despite the dependency). Recent files at `<userData>/recent-files.json`.
 ## System Dependencies
 | Dependency | Required | Notes |
 |---|---|---|
 | **Node.js** | >= 20 | Electron 41 bundles Node 20.x |
 | **Pandoc** | Yes (for exports) | Downloaded to `bin/<platform>/pandoc` via `scripts/download-tools.js` (v3.9.0.2). Falls back to system PATH. Must be present for DOCX/ODT/EPUB/LaTeX/PPTX export. |
 | **FFmpeg** | Bundled | `ffmpeg-static` npm package; `asarUnpacked` for packaged builds |
 | **MiKTeX / TeX Live** | Optional | For LaTeX PDF export; MiKTeX PATH injected on Windows automatically |
 | **ImageMagick** | Optional | Linux image conversion; listed as deb dependency |
 | **LibreOffice** | Optional | Enhanced document conversion; listed as deb dependency |
 ## Development Commands
 ### Prerequisites
 ```bash
-npm start                  # Launch Electron app (dev mode)
+# Install Node.js dependencies
-npm test                   # Jest test suite
+npm install
-npm test:watch             # Jest in watch mode
+
-npm test:coverage          # Jest with coverage report
+# Install Pandoc (required for export functionality)
-npm run lint               # ESLint check (src + tests)
+# Ubuntu/Debian:
-npm run lint:fix           # ESLint auto-fix
+sudo apt-get install pandoc
-npm run format             # Prettier write
+
-npm run format:check       # Prettier check only
+# macOS:
-npm run download-tools     # Download Pandoc binaries to bin/
+brew install pandoc
-npm run generate-icons     # Generate app icons via sharp
+
 # Windows: Download from https://pandoc.org/installing.html
 ```
-## Build & Package
+### Running the Application
 ```bash
 # Start development server
 npm start
-**Tool:** `electron-builder` (v26.0.12), config inline in `package.json` (no separate config file).
+# Start with debugging
 npm start --enable-logging
 ```
-| Target | Platforms |
+### Building & Packaging
 |---|---|
 | `npm run build` | electron-builder (default platform) |
 | `npm run build:win` | Windows: NSIS installer + portable + zip (x64) |
 | `npm run build:mac` | macOS: default dmg |
 | `npm run build:linux` | Linux: deb + AppImage + snap |
 | `npm run dist` | Build without publish |
 | `npm run dist:all` | Build for all platforms |
-**Bundled with builds:** Pandoc binary per platform. FFmpeg via `ffmpeg-static` (asarUnpacked). NSIS installer uses custom script at `scripts/nsis-installer.nsh`.
+```bash
 # Generate application icons
 npm run generate-icons
-**Output:** `dist/` directory.
+# Build for current platform
 npm run build
-**CI:** GitHub Actions workflows in `.github/workflows/` (ci.yml, release.yml).
+# Platform-specific builds
 npm run build:win      # Windows
 npm run build:mac      # macOS
 npm run build:linux    # Linux (AppImage, .deb, .snap)
-## Project Conventions / Gotchas
+# Build for all platforms
 npm run dist:all
 ```
- **No bundler/transpilation.** The app uses vanilla CommonJS JavaScript. `src/main.js` is loaded directly by Electron. No webpack, no Vite, no TypeScript, no Babel.
+### Git Branch Management
- **Monolithic files.** `main.js` (4,260 lines) and `renderer.js` (5,361 lines) contain most logic. Not ideal but is the current state of this branch.
+```bash
- **CodeMirror 6** for the editor, configured in `src/editor/codemirror-setup.js`.
+# Switch to platform-specific branches
- **PDF rendering** uses `pdfjs-dist`; **PDF manipulation** uses `pdf-lib` in the main process.
+git checkout linux    # Linux development
- **Renderer security is weak** — full Node access in renderer. Do NOT introduce new privileged renderer code without understanding this.
+git checkout macos     # macOS development  
- **Pandoc is external.** Must be installed separately or downloaded via `npm run download-tools`. HTML and built-in PDF export work without Pandoc; other formats require it.
+git checkout windows   # Windows development
- **PDF export fallback chain:** xelatex -> pdflatex -> lualatex -> Electron built-in `printToPDF()`.
+git checkout master    # Main development branch
- **ESLint flat config** (`eslint.config.js`) with ECMAScript 2022. Prettier with 2-space indent, single quotes, semicolons, 100-char width.
+
- **Tests:** Jest with jsdom environment, 15% coverage threshold. 24 test files in `tests/`.
+# Update all branches with latest changes
- **File associations:** `.md`, `.markdown`, `.pdf` registered at install.
+git checkout master
- **Single instance lock** enforced via `app.requestSingleInstanceLock()`.
+git push origin master
- **Adapters layer** (`src/adapters/`) abstracts file system operations for potential future non-Electron targets.
+git checkout linux && git merge master && git push origin linux
 git checkout macos && git merge master && git push origin macos
 git checkout windows && git merge master && git push origin windows
 ```
 ### Release Management
 ```bash
 # Create and push release tag
 git tag v1.2.1 -m "Release message"
 git push origin v1.2.1
 # Create GitHub release with packages
 gh release create v1.2.1 --title "Title" --notes "Release notes" \

 MarkdownConverter distributes the following binaries built from GPL-licensed
 software. Per GPL §3(b), this document is the written offer: **corresponding
 source code for the exact versions listed below is available on request for
 at least three years from each release**, and permanently at the referenced
 public locations. Write to: amit.wh@gmail.com (or open a GitHub issue at
 https://github.com/amitwh/markdown-converter/issues).
 ## Pandoc — GPL-2.0-or-later
 - Binary shipped: `bin/pandoc` (v3.9.0.2, official upstream release, unmodified)
 - SHA-256 (linux): `7d124235998ecd3cdd9a463b1e5f6691a178b6461824c29a36170a0882f05597`
 - Source: <https://github.com/jgm/pandoc/archive/refs/tags/3.9.0.2.tar.gz>
 - Pandoc statically links Haskell libraries (GHC ecosystem, mostly BSD-3);
  their sources are included in the upstream release tarball's dependency set.
 ## FFmpeg — GPL-3.0-or-later (build configuration)
 - Binary shipped: `ffmpeg` provided by the npm package `ffmpeg-static@5.3.0`
  (Linux: johnvansickle.com build; Windows: gyan.dev; macOS: evermeet.cx —
  all `--enable-gpl` builds including x264/x265, per the build banner)
 - Source:
  - FFmpeg: <https://ffmpeg.org/releases/> (use the release matching
    `ffmpeg -version` of the shipped binary)
  - Build scripts & pinned versions: <https://github.com/eugeneware/ffmpeg-static>

    x265: <https://bitbucket.org/multicoreware/x265_git/> ·
    other `--enable-lib*` components: their upstream sources (all free/open)
 ## PyInstaller bootloader (inside the bundled MarkItDown binary) — GPL-2.0 with boot-exception
 - Binary shipped: `bin/markitdown` (MarkItDown 0.1.7 frozen with PyInstaller 6.x)
 - PyInstaller grants a special exception allowing the bootloader to be
  embedded in non-GPL frozen applications; source anyway:
  <https://github.com/pyinstaller/pyinstaller>
 - Everything frozen above the bootloader (markitdown + Python packages +
  CPython runtime) is permissively licensed (MIT/Apache/BSD/PSF/MPL);
  see THIRD-PARTY-NOTICES.md §2 for the list.
 - CPython runtime source: <https://www.python.org/downloads/source/>
  (PSF License — not GPL, listed here for completeness).
 ## libvips (via sharp prebuilt binaries) — LGPL-2.1-or-later
 - Shipped as dynamically-loaded libraries from `@img/*` prebuilts for sharp 0.35.4
 - Source: <https://github.com/libvips/libvips> · prebuilt bundle sources:
  <https://github.com/lovell/sharp-builds>
 - LGPL compliance: the app's own source is public (MIT) and the libraries
  remain separately replaceable files in the installation directory
  (`node_modules/@img/`), satisfying the relinking requirement.

 # PanConverter - Updates & Changelog
 ## Version 4.7.0 (2026-09-05)
 ### Bundling & Legal Compliance
 - **MarkItDown is now bundled**: `npm run bundle:markitdown` freezes Microsoft's
  markitdown (MIT) + embedded Python runtime into a single ~75MB per-platform
  binary (`bin/<platform>/markitdown`) via PyInstaller (ML extras excluded);
  the app prefers the bundled binary and falls back to system installs
 - Packaging copies the bundled markitdown for Windows/macOS/Linux alongside Pandoc
 - **THIRD-PARTY-NOTICES.md** — full license inventory of everything distributed
  (bundled binaries, npm runtime deps, fonts, embedded Python packages)
 - **SOURCES.md** — GPL §3(b) written source offer for Pandoc / FFmpeg (GPL build) /
  PyInstaller bootloader, with pinned versions + SHA-256; LGPL relinking note for libvips
 - **third-party-licenses/** — canonical texts: GPL-2.0, LGPL-2.1, MPL-2.0,
  Apache-2.0, OFL-1.1, PSF-Python
 - **Help → Third-Party Notices & Licenses** — in-app viewer for both documents
 - **download-tools.js** now SHA-256 pins and verifies every downloaded artifact
  (post-download and against the cache on every run; hard-fails on mismatch)
 - README gains a "Bundled Dependencies, Legal Notices & Credits" section
 - Large optional tools intentionally NOT bundled (documented): LibreOffice,
  MiKTeX/TeX Live, ImageMagick, PlantUML+JRE, Calibre
 ---
 ## Version 4.6.1 (2026-09-05)
 ### New Features
 - **MarkItDown import** — "File → Import with MarkItDown (Any Format)…" embeds
  Microsoft's [markitdown](https://github.com/microsoft/markitdown) (MIT) as an
  any-file → Markdown path: PDF, DOCX, PPTX, XLSX, Outlook .msg/.eml, EPUB,
  images, CSV/JSON/XML, ZIP; audio transcription and OCR with the `[all]` extras
  - Command auto-resolution: `markitdown` binary, then `python -m markitdown` /
    `python3 -m markitdown` (probed once, cached)
  - Same SEC-1 argv discipline as Pandoc (execFile only, paths never through a shell),
    50MB input cap, 120s timeout, path-sanitized errors that surface markitdown's
    actionable `pip install 'markitdown[...]'` hints
  - Output written next to the source as `<name>.md` (numeric suffix instead of
    overwriting) and opened in a new tab; `markitdown:available` / `markitdown:convert`
    IPC for future renderer flows
 - **AI Assistant: Anthropic-compatible provider** — any base URL speaking the
  Anthropic messages schema (LiteLLM proxies, Bedrock gateways, local servers);
  x-api-key + Bearer auth, keyless proxies supported, tolerates bases with or
  without a trailing `/v1`
 ### Bug Fixes
 - File → Open PDF crashed the PDF editor (null operation matched no section; now
  defaults to Merge)
 - Backlinks panel required the wrong module path (failed at registration)
 - writing-studio engines/panels now await their IPC-backed settings/file backends
  (eliminates `JSON.parse("[object Promise]")` crashes)
 - Manuscript panel's window.prompt (unsupported in Electron) replaced with an
  inline dialog; collaboration comment store made async to match its IO
 ---
 ## Version 4.6.0 (2026-09-05)
 ### New Features
 #### AI Assistant Plugin (multi-provider)
 - Chat sidebar panel with rolling conversation history and insert-reply-into-document
 - Providers: OpenAI, Anthropic, Ollama, LM Studio, and any OpenAI-compatible endpoint
 - All provider traffic proxied through the main process — API keys never enter the renderer and the CSP stays closed to AI endpoints
 - Commands: AI Summarize / Improve / Explain / Translate selection
 - Answers the writing-studio `ai:analyze` contract, finally enabling the Proofread panel
 #### Collaboration Plugin (inline comments)
 - Anchor-based comments stored in `.comments/` sidecar files (never exported, never committed)
 - Comments sidebar panel: add at cursor, list, resolve, delete, jump to anchor
 - Drift detection flags moved/edited anchors; F8 navigates to the next open comment
 #### Local Knowledge Base (wiki-links + backlinks)
 - `[[Note]]`, `[[Note|alias]]`, `[[Note#section]]` render as links in the preview (code blocks excluded)
 - Clicking a wiki-link opens the note or offers to create it
 - Backlinks sidebar panel scans the folder (bounded BFS) for documents linking to the current one
 #### Crash Recovery / Session Restore
 - Open tabs (paths + unsaved buffer content) snapshotted to localStorage, debounced on edits, on tab changes, on unload, and once a minute
 - Restore prompt on launch with per-tab restore, clean-fresh option, and 2MB content budget
 #### Document Version History
 - Every save snapshots the previous on-disk content to `<userData>/versions/`
 - History sidebar panel: list, restore (with safety snapshot), unified diff vs. current, delete, manual "save version now"
 - Per-document pruning (20 versions), path-hash storage, id-validated reads
 #### Editor
 - Vim keybindings (View → Vim Mode, persisted, live toggle via CodeMirror Compartment)
 - Snippet Tab-expansion: type a snippet name and press Tab to insert it
 - Zen Mode word-goal setter (the HUD progress bar finally has UI)
 #### Export / Conversion
 - **Real PDF encryption**: pdf-lib swapped for @cantoo/pdf-lib — encrypt/decrypt/permissions now actually work (UI auto-enables via the capability probe)
 - **XLSX export**: markdown tables → native Excel workbook, one sheet per table (no Pandoc needed)
 - **ODT headers/footers + page size**: real ODF styles.xml patching replaces the empty stub
 - **Local PlantUML rendering**: diagrams render on-machine via the `plantuml` CLI when installed; plantuml.com stays as fallback
 - **KaTeX bundled locally** (CSS + fonts): math renders offline, no CDN calls
 - Writing heatmap (GitHub-style 30-day grid) in the writing-studio Goals panel
 #### Platform
 - Quick Note global scratchpad (Ctrl+Alt+Q, works when unfocused; appends to `notes/quick-notes.md`)
 - Deep link protocol `markdownconverter://open?path=…`
 - REPL confirmation dialog before first code execution per language per session (unsandboxed-execution guard rail)
 - Writing-studio's four sidebar panels (Manuscript/Goals/Snapshots/Proofread) are now actually wired with rail icons
 - Plugin sidebar panels get automatic rail icons via `registerPanel({icon})`
 ### Bug Fixes
 - `Ctrl+Shift+P` collision: PDF (Enhanced) export now `Ctrl+Alt+Shift+P`; Command Palette keeps `Ctrl+Shift+P`
 - Universal Converter's Pandoc tool no longer always reports "not installed" (`checkConverterAvailable` gained a pandoc case with bundled-binary check)
 - CLI headless export: removed dangling `--css` / `--reference-doc` flags that made pandoc exit with an error; `--self-contained` replaced with `--standalone` (Pandoc 3.x)
 - Removed dead "Open Export Options Dialog…" button from the converter dialog
 - Removed duplicate `styles-zen.css` include
 ### Security
 - AI provider requests carry size caps (200KB prompt), timeouts (120s), and user-safe error surfaces
 - Version-history reads validate ids against traversal; history listing requires a valid document path
 - PlantUML local rendering removes the diagram-text exfiltration path when a local CLI exists (CVE-MC-007 follow-up)
 ### Tests
 - New suites: OdtStyling, AiProviders, ai-assistant prompts, collaboration comment-store, wiki-links/backlinks, session-store, XlsxExporter, VersionHistory
 - PDFOperations encryption tests rewritten for the real-encryption reality
