**Features Implemented:**
- ✅ **Essential Documents Section** - Pinned critical docs (Insurance, Registration, Owner's Manual)
- ✅ **Browse by Category** - 8 category cards with gradients and animations
- ✅ **Role Switcher** - Owner, Captain, Manager, Crew views (UI complete)
- ✅ **Recent Activity** - Timeline of uploads, views, shares
- ✅ **File Type Badges** - PDF, XLSX, JPG with color coding
- ✅ **Expiration Alerts** - Insurance expiration countdown

- ✅ **Responsive Design** - Mobile/tablet/desktop breakpoints

**Design System Applied:**
```css
✓ Pink/Purple gradients (primary-500, secondary-500)
✓ Glass morphism (backdrop-filter: blur(12px))
✓ Smooth animations (transition: 0.3s cubic-bezier)
✓ Badge system (success, primary, warning)
✓ Hover effects (scale, translate, color shift)
✓ Staggered fade-in animations (0.1s-0.45s delays)
```

**Route Added:** `/library` → `LibraryView.vue`

## 🔒 Security Audit Results

### 2. Multi-Tenancy Audit ⚠️ CRITICAL ISSUES FOUND

**Report:** `/home/setup/navidocs/docs/analysis/MULTI_TENANCY_AUDIT.md` (600+ lines)

**Security Rating:** 🔴 **CRITICAL VULNERABILITIES**

**Critical Findings (5 vulnerabilities):**

1. **No Authentication Enforcement** ⚠️
   - All routes fall back to `test-user-id` instead of requiring JWT
   - **Risk:** Anyone can access any document
   - **Fix:** Add `authenticateToken` middleware to all routes

2. **DELETE Endpoint Completely Unprotected** 🚨
   - Any user can delete ANY document without access checks
   - **Code:** `server/routes/documents.js:354-414`
   - **Fix:** Add organization membership verification

3. **STATS Endpoint Exposes All Data** ⚠️
   - Shows statistics across ALL tenants
   - **Code:** `server/routes/stats.js`
   - **Fix:** Filter by user's organizations

4. **Upload Accepts Arbitrary organizationId** ⚠️
   - Users can upload docs to any organization
   - **Fix:** Validate user has access to organizationId

5. **Upload Auto-Creates Organizations** ⚠️
   - Allows creation of arbitrary organizations
   - **Fix:** Remove auto-creation, require pre-existing orgs

**Well-Implemented Features:** ✅
- Document listing uses proper INNER JOIN (excellent)
- Search token correctly scopes to organizations
- Image access control verifies membership
- Path traversal protection
- SQL injection protection via parameterized queries

### 3. Disappearing Documents Bug Investigation 🐛

**Report:** `/home/setup/navidocs/docs/analysis/DISAPPEARING_DOCUMENTS_BUG_REPORT.md` (800+ lines)

**Root Causes Identified:**

1. **🚨 HIGH RISK: Dangerous Cleanup Scripts**
   - `scripts/keep-last-n.js` - Defaults to keeping only 2 documents!
   - `scripts/clean-duplicates.js` - Deletes duplicates without confirmation
   - **No safeguards** against accidental mass deletion
   - **Most Likely Culprit:** Someone ran `node scripts/keep-last-n.js` without args

2. **🚨 HIGH RISK: Hard Delete Endpoint**
   - DELETE `/api/documents/:id` permanently removes documents
   - No authentication/authorization (marked as "TODO")
   - Cascades to filesystem and search index
   - **No soft delete** - data is gone forever

3. **⚠️ MEDIUM RISK: Status Transition Issues**
   - Documents stuck in "processing" if OCR worker crashes
   - Failed documents remain "failed" forever (no retry)
   - No timeout detection for stale jobs

4. **⚠️ MEDIUM RISK: CASCADE Deletions**
   - Deleting organization deletes ALL its documents
   - Foreign key cascade rules in schema

5. **ℹ️ LOW RISK: Search Index Sync Failures**
   - Indexing failures silently ignored
   - Documents appear "missing" from search but exist in DB

**Recommended Fixes (Prioritized):**

**Priority 1 (CRITICAL):**
```bash
# Add confirmation prompts to cleanup scripts
# Require minimum values (keep at least 5 documents)
scripts/keep-last-n.js --keep 10 --confirm
```

**Priority 2 (HIGH):**
```javascript
// Implement soft delete
UPDATE documents SET status = 'deleted', deleted_at = ? WHERE id = ?

// Add admin-only hard delete endpoint
router.delete('/admin/documents/:id/purge', authenticateAdmin, hardDelete)
```

**Priority 3 (MEDIUM):**
```javascript
// Add stale job detection (timeout after 30 minutes)
const staleJobs = db.prepare(`
  SELECT * FROM documents
  WHERE status = 'processing'
  AND updated_at < datetime('now', '-30 minutes')
`).all()

// Add retry for failed documents
router.post('/documents/:id/retry', async (req, res) => {
  // Re-queue OCR job
})
```

## 🏗️ Architecture Analysis

### Database Schema (Verified) ✅
```sql
-- Multi-tenancy ready
organizations (id, name, created_at)
user_organizations (user_id, organization_id, role)
documents (id, organization_id, title, status, ...)

-- Proper foreign keys with CASCADE
FOREIGN KEY (organization_id) REFERENCES organizations(id) ON DELETE CASCADE
```

**Status:** Well-designed, multi-tenant ready, proper indexing

---

## 🎯 Implementation Status

### What's Working ✅
1. **UI/UX:** Beautiful library view with animations
2. **Database:** Solid multi-tenant schema
3. **Document Listing:** Proper org filtering (INNER JOIN)
4. **Search Scoping:** Tenant-isolated search tokens
5. **Image Access:** Organization membership verified

### What Needs Fixing 🚨
1. **Authentication:** Add JWT middleware to ALL routes
2. **Authorization:** Verify org membership before mutations
3. **Soft Delete:** Replace hard delete with status='deleted'
4. **Cleanup Scripts:** Add confirmation prompts
5. **Status Management:** Add retry mechanism for failed docs

### What's Missing ⏳
1. **API Integration:** LibraryView needs real data (currently static)
2. **State Management:** Add Pinia for role switching
3. **Loading States:** Add spinners for async operations
4. **Error Handling:** Add user-friendly error messages
5. **Accessibility:** Add ARIA attributes to all interactive elements

## 🔧 Immediate Next Steps

### Priority 1: Fix Security Issues (1-2 days)
```javascript
// 1. Add authentication middleware
router.use('/api', authenticateToken)

// 2. Add authorization to DELETE
router.delete('/documents/:id', async (req, res) => {
  const doc = getDocument(req.params.id)
  const userOrgs = getUserOrganizations(req.user.id)

  if (!userOrgs.includes(doc.organization_id)) {
    return res.status(403).json({ error: 'Unauthorized' })
  }

  // Soft delete instead of hard delete
  db.prepare('UPDATE documents SET status = ? WHERE id = ?')
    .run('deleted', req.params.id)
})

// 3. Filter stats by organization
router.get('/stats', async (req, res) => {
  const userOrgs = getUserOrganizations(req.user.id)
  const stats = getStats(userOrgs) // Filter by user's orgs
  res.json(stats)
})

// 4. Validate organizationId on upload
router.post('/upload', async (req, res) => {
  const { organizationId } = req.body
  const userOrgs = getUserOrganizations(req.user.id)

  if (!userOrgs.includes(organizationId)) {
    return res.status(403).json({ error: 'Not a member of this organization' })
  }

  // Proceed with upload
})

// 5. Remove auto-organization creation
// Delete this code block from upload route
```

### Priority 2: Fix Cleanup Scripts (30 minutes)
```javascript
// scripts/keep-last-n.js - Add safeguards
const keepCount = process.argv[2] ? parseInt(process.argv[2]) : null

if (!keepCount || keepCount < 5) {
  console.error('❌ Error: Must keep at least 5 documents')
  console.log('Usage: node keep-last-n.js 10')
  process.exit(1)
}

console.log(`⚠️  WARNING: This will delete ${total - keepCount} documents`)
console.log('Type "yes" to confirm:')

const readline = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
})

readline.question('> ', (answer) => {
  if (answer.toLowerCase() === 'yes') {
    // Proceed with deletion
  } else {
    console.log('Cancelled')
  }
  readline.close()
})
```

### Priority 3: Integrate Library API (1-2 days)
```javascript
// LibraryView.vue - Add real API calls
import { ref, onMounted } from 'vue'

const documents = ref([])
const loading = ref(true)

onMounted(async () => {
  try {
    const response = await fetch('/api/documents?organizationId=liliane1')
    const data = await response.json()
    documents.value = data.documents
  } catch (error) {
    console.error('Failed to load documents:', error)
    toast.error('Failed to load documents')
  } finally {
    loading.value = false
  }
})
```
