 The `BlurView` in `tabBarBackground` is unreliable and can fail during re-renders/transitions, causing a fully transparent tab bar. The solid rgba background acts as a fallback while still allowing the blur effect on top.

-## E2EE (End-to-End Encryption) Implementation
-
-Chat messages (text, images, videos) are encrypted client-side using AES-256-GCM with triple-wrapped RSA keys.
-
-### Architecture
-- **Full documentation:** See `docs/e2ee-implementation.md` for complete details
-- **Encryption library:** `apps/mobile/src/lib/encryption/`
-- **React hooks:** `apps/mobile/src/hooks/useEncryptionKeys.ts`, `useDecryptedMessage.ts`
-- **Edge functions:** `handle-key-rotation`, `reencrypt-pending-messages`
-
-### Key Concepts
-1. **Message versions:** v1 = plaintext (legacy), v2 = E2EE
-2. **Triple-wrapped keys:** Each message's AES key is RSA-encrypted for sender, recipient, and admin
-3. **Device recovery:** When user gets new device, admin key re-wraps messages for new user key
-
-### Database Tables
-- `messages.version` - Encryption version (1 or 2)
-- `messages.encrypted_content` - Base64 ciphertext
-- `messages.encryption_iv` - Base64 IV for AES-GCM
-- `messages.keys_metadata` - JSONB with wrapped keys
-- `profiles.public_key_jwk` - User's RSA public key
-- `master_keys` - Admin RSA public keys
-
-### Setup Required
-1. Run `node scripts/generate-admin-keys.mjs` to generate admin keypair
-2. Insert public key into `master_keys` table
-3. Store private key in `ADMIN_PRIVATE_KEY_JWK` environment variable for edge functions
-4. Install crypto dependency: `npm install react-native-quick-crypto@^0.7.x`
-5. Run `npx expo prebuild --clean` after installation
-
-### Edge Functions for E2EE
-| Function | verify_jwt | Purpose |
-|----------|------------|---------|
-| `handle-key-rotation` | false | Re-wraps message keys when user gets new device |
-| `reencrypt-pending-messages` | false | Wraps keys for recipient after they generate keys |

+# Pack Icons: Admin-First Approach
+
+## Problem Statement
+
+The current pack icon system uses emojis stored in the database, which creates a "AI slop" appearance. We've added a frontend mapping from emojis to Ionicons, but this is fragile:
+
+- New packs require manual code changes to add mappings
+- The mapping is hidden from admins
+- It's a maintenance burden
+
+## Solution: Admin-First Icon Selection
+
+Allow admins to select Ionicons directly in the admin UI, storing the Ionicon name (e.g., `"briefcase-outline"`) in the database instead of emojis.
+
+## Backwards Compatibility
+
+**Important**: We must maintain backwards compatibility with the app currently in App Store review.
+
+| App Version | DB has emoji "💼" | DB has "briefcase-outline" |
+|-------------|-------------------|---------------------------|
+| Old (in review) | Shows emoji | Shows literal text (broken) |
+| New (with mapping) | Maps to Ionicon | Uses directly |
+
+### Strategy
+
+1. **Don't migrate existing data** - existing packs keep their emojis
+2. **New packs use Ionicon names** - admin UI stores Ionicon names
+3. **Mobile handles both formats** - detect format and handle appropriately
+
+This ensures:
+- Old app continues working with existing emoji packs
+- New packs show default icon on old app (acceptable degradation)
+- New app handles everything correctly
+
+---
+
+## Implementation Tasks
+
+### Task 1: Create Ionicon Picker Component (Admin)
+
+**File**: `apps/admin/src/components/ui/icon-picker.tsx` (new file)
+
+Create a new component that displays a grid of available Ionicons for selection.
+
+**Requirements**:
+- Display commonly used Ionicons in a grid/dropdown
+- Show icon preview with name
+- Search/filter functionality (optional)
+- Return the Ionicon name string (e.g., `"briefcase-outline"`)
+
+**Suggested Icons to Include**:
+```typescript
+const AVAILABLE_ICONS = [
+  // Relationships & Love
+  'heart-outline', 'heart-half-outline', 'heart-circle-outline',
+
+  // Communication
+  'chatbubbles-outline', 'chatbox-outline', 'mail-outline',
+
+  // Romance & Dates
+  'flower-outline', 'wine-outline', 'restaurant-outline', 'cafe-outline',
+
+  // Adventure & Travel
+  'airplane-outline', 'car-outline', 'compass-outline', 'map-outline',
+
+  // Home & Family
+  'home-outline', 'people-outline', 'person-outline',
+
+  // Mystery & Secrets
+  'eye-off-outline', 'key-outline', 'lock-closed-outline',
+
+  // Fun & Games
+  'dice-outline', 'gift-outline', 'sparkles-outline', 'star-outline',
+
+  // Intimacy
+  'flame-outline', 'flash-outline', 'moon-outline', 'sunny-outline',
+
+  // Goals & Planning
+  'flag-outline', 'calendar-outline', 'checkbox-outline', 'trophy-outline',
+
+  // General
+  'layers-outline', 'cube-outline', 'folder-outline', 'bookmark-outline',
+  'bulb-outline', 'color-wand-outline', 'sync-outline', 'refresh-outline',
+];
+```
+
+**Component Interface**:
+```typescript
+interface IconPickerProps {
+  value: string;
+  onChange: (iconName: string) => void;
+}
+```
+
+---
+
+### Task 2: Update Pack Form Dialog (Admin)
+
+**File**: `apps/admin/src/components/content/PackFormDialog.tsx`
+
+**Changes**:
+1. Import new `IconPicker` component
+2. Replace `EmojiPicker` with `IconPicker` for the icon field
+
+**Current code (line ~101-104)**:
+```tsx
+<EmojiPicker
+    value={formData.icon}
+    onChange={(emoji) => setField('icon', emoji)}
+/>
+```
+
+**New code**:
+```tsx
+<IconPicker
+    value={formData.icon}
+    onChange={(iconName) => setField('icon', iconName)}
+/>
+```
+
+3. Update default icon in `initialFormData` (line ~41):
+```typescript
+// Change from '💕' to:
+icon: 'heart-outline',
+```
+
+---
+
+### Task 3: Update Category Form (Admin)
+
+**File**: `apps/admin/src/pages/content/CategoriesPage.tsx`
+
+Same changes as Task 2 - replace `EmojiPicker` with `IconPicker` for category icons.
+
+---
+
+### Task 4: Update AI Pack Generator (Admin)
+
+**File**: `apps/admin/src/lib/ai/generators/packs.ts`
+
+Update the AI prompt to suggest Ionicon names instead of emojis.
+
+**Current (line ~147)**:
+```typescript
+- icon: A single descriptive emoji
+```
+
+**New**:
+```typescript
+- icon: An Ionicon name from this list: heart-outline, flame-outline, sparkles-outline, gift-outline, wine-outline, airplane-outline, home-outline, key-outline, flash-outline, sunny-outline, flower-outline, star-outline, dice-outline, compass-outline, bulb-outline
+```
+
+---
+
+### Task 5: Update Mobile Icon Utility
+
+**File**: `apps/mobile/src/lib/packIcons.ts`
+
+Update `getPackIconName()` to handle both Ionicon names and legacy emojis.
+
+**New implementation**:
+```typescript
+import type { Ionicons } from "@expo/vector-icons";
+
+type IoniconsName = keyof typeof Ionicons.glyphMap;
+
+// Legacy emoji mappings (for backwards compatibility with existing packs)
+const EMOJI_TO_IONICON: Record<string, IoniconsName> = {
+    "💼": "briefcase-outline",
+    "🔗": "heart-half-outline",
+    "❤️": "heart-outline",
+    "💫": "sparkles-outline",
+    "🤫": "eye-off-outline",
+    "🗝️": "key-outline",
+    "🌹": "flower-outline",
+    "🍷": "wine-outline",
+    "✨": "sparkles-outline",
+    "✈️": "airplane-outline",
+    "🚗": "car-outline",
+    "🏡": "home-outline",
+    "🎭": "color-wand-outline",
+    "🎲": "dice-outline",
+    "🎁": "gift-outline",
+    "🔄": "sync-outline",
+    "😈": "flash-outline",
+    "🔥": "flame-outline",
+    "🎯": "flag-outline",
+    "☀️": "sunny-outline",
+    "📦": "cube-outline",
+    "📁": "folder-outline",
+};
+
+export const DEFAULT_PACK_ICON: IoniconsName = "layers-outline";
+
+// List of valid Ionicon names (subset we support)
+const VALID_IONICONS = new Set([
+    'heart-outline', 'heart-half-outline', 'heart-circle-outline',
+    'chatbubbles-outline', 'chatbox-outline', 'mail-outline',
+    'flower-outline', 'wine-outline', 'restaurant-outline', 'cafe-outline',
+    'airplane-outline', 'car-outline', 'compass-outline', 'map-outline',
+    'home-outline', 'people-outline', 'person-outline',
+    'eye-off-outline', 'key-outline', 'lock-closed-outline',
+    'dice-outline', 'gift-outline', 'sparkles-outline', 'star-outline',
+    'flame-outline', 'flash-outline', 'moon-outline', 'sunny-outline',
+    'flag-outline', 'calendar-outline', 'checkbox-outline', 'trophy-outline',
+    'layers-outline', 'cube-outline', 'folder-outline', 'bookmark-outline',
+    'bulb-outline', 'color-wand-outline', 'sync-outline', 'refresh-outline',
+    'briefcase-outline',
+]);
+
+/**
+ * Converts an icon value to an Ionicons name.
+ * Handles both:
+ * - Ionicon names directly (new packs): "briefcase-outline" -> "briefcase-outline"
+ * - Legacy emojis (existing packs): "💼" -> "briefcase-outline"
+ */
+export function getPackIconName(icon: string | null | undefined): IoniconsName {
+    if (!icon) return DEFAULT_PACK_ICON;
+
+    // Check if it's already a valid Ionicon name
+    if (VALID_IONICONS.has(icon)) {
+        return icon as IoniconsName;
+    }
+
+    // Fall back to emoji mapping for legacy data
+    return EMOJI_TO_IONICON[icon] || DEFAULT_PACK_ICON;
+}
+```
+
+---
+
+### Task 6: Add Ionicons Package to Admin (if needed)
+
+**File**: `apps/admin/package.json`
+
+The admin app may need the Ionicons package to display icon previews.
+
+```bash
+cd apps/admin
+npm install react-icons
+```
+
+Then use `IoIcons` from `react-icons/io5` which matches Ionicons naming.
+
+Alternatively, create simple SVG components or use icon font directly.
+
+---
+
+## File Summary
+
+| File | Action | Priority |
+|------|--------|----------|
+| `apps/admin/src/components/ui/icon-picker.tsx` | Create | High |
+| `apps/admin/src/components/content/PackFormDialog.tsx` | Modify | High |
+| `apps/admin/src/pages/content/CategoriesPage.tsx` | Modify | Medium |
+| `apps/admin/src/lib/ai/generators/packs.ts` | Modify | Low |
+| `apps/mobile/src/lib/packIcons.ts` | Modify | High |
+| `apps/admin/package.json` | Modify (maybe) | Medium |
+
+---
+
+## Testing Checklist
+
+- [ ] Create a new pack in admin with Ionicon - verify it saves correctly
+- [ ] Edit an existing pack (with emoji) - verify emoji still displays in picker
+- [ ] Mobile app displays new Ionicon packs correctly
+- [ ] Mobile app displays legacy emoji packs correctly (via mapping)
+- [ ] Old app version (if testable) shows default icon for new Ionicon packs
+
+---
+
+## Future Considerations
+
+Once the new app version is widely deployed:
+1. **Optional**: Run a database migration to convert remaining emojis to Ionicons
+2. **Optional**: Remove emoji mapping code from mobile app
+3. **Optional**: Add migration script admins can run per-pack
+
+For now, the backwards-compatible approach means no database migrations and no breaking changes.

+# Plan: Remove E2EE and Switch to Server-Side Security
+
+## Overview
+
+This document outlines the plan to remove end-to-end encryption (E2EE) from Sauci's chat system and rely on Supabase's built-in security instead.
+
+### Current State
+
+- Messages are encrypted client-side using AES-256-GCM with triple-wrapped RSA keys
+- Each message has sender, recipient, and admin wrapped keys
+- Complex key management: generation, storage, rotation, recovery
+- ~2500+ lines of encryption code across 21 files
+- Edge functions handle key rotation and pending message re-encryption
+
+### Target State
+
+- Messages stored as plaintext in Supabase (protected by RLS policies)
+- TLS encryption in transit (Supabase default)
+- Encryption at rest (Supabase infrastructure)
+- No client-side key management
+- Simplified chat code
+
+### Why Remove E2EE?
+
+1. **Complexity** - Triple-wrapped keys, device recovery, key rotation adds significant maintenance burden
+2. **Overkill** - For a couples intimacy app, server-side security is sufficient
+3. **User Experience** - E2EE adds latency, recovery flows, and potential failure modes
+4. **Development Velocity** - Simpler code = faster iteration
+
+### Security Model After Removal
+
+- **In Transit**: TLS 1.3 (Supabase default)
+- **At Rest**: Supabase encrypts data at rest
+- **Access Control**: RLS policies restrict access to couple's own messages
+- **Admin Access**: Admins can read messages (same as current E2EE with admin key)
+
+---
+
+## Migration Strategy for Existing Messages
+
+Existing v2 (encrypted) messages need handling. Options:
+
+### Option A: Decrypt and Convert (Recommended)
+
+Run a one-time migration to decrypt all v2 messages using admin key and store as v1 plaintext.
+
+- Pros: Clean slate, no legacy code needed
+- Cons: Requires admin private key, one-time effort
+
+### Option B: Leave v2 Messages As-Is
+
+Keep encrypted messages in database but stop creating new ones. Old messages become unreadable.
+
+- Pros: Simpler migration
+- Cons: Users lose access to old messages
+
+### Option C: Hybrid Display
+
+Keep decryption code for reading old v2 messages, but send new messages as v1.
+
+- Pros: No data loss
+- Cons: Maintains complexity, defeats purpose of removal
+
+**Recommendation**: Option A - decrypt existing messages during migration window.
+
+---
+
+## Tasks
+
+### Phase 1: Database Migration (Estimated: 2-3 hours)
+
+#### Task 1.1: Create Migration to Decrypt Existing v2 Messages
+
+Create an edge function that:
+
+1. Fetches all messages with `version = 2`
+2. Decrypts each using admin private key
+3. Updates to `version = 1`, moves decrypted content to `content` column
+4. Clears `encrypted_content`, `encryption_iv`, `keys_metadata`
+
+**Files to create:**
+
+- `apps/supabase/functions/migrate-e2ee-to-plaintext/index.ts`
+
+#### Task 1.2: Run Migration
+
+Execute the migration function against both non-prod and prod databases.
+
+#### Task 1.3: Verify Migration
+
+Query to confirm no v2 messages remain:
+
+```sql
+SELECT COUNT(*) FROM messages WHERE version = 2;
+```

+
+```json
+"NSCameraUsageDescription": "Sauci uses your camera to take photos and videos that you can share privately with your partner in encrypted chat messages.",
+"NSPhotoLibraryUsageDescription": "Sauci uses your photo library so you can select photos and videos to share privately with your partner in encrypted chat messages.",
+```
+
+**Updated strings:**

+## Estimated Total Effort
+
+| Phase                           | Estimated Time   |
+| ------------------------------- | ---------------- |
+| Phase 1: Database Migration     | 2-3 hours        |
+| Phase 2: Remove Encryption Code | 4-6 hours        |
+| Phase 3: Simplify Chat Components | 3-4 hours      |
+| Phase 4: Clean Up State         | 1-2 hours        |
+| Phase 5: Remove Edge Functions  | 1 hour           |
+| Phase 6: Database Cleanup       | 1 hour (optional)|
+| Phase 7: Testing                | 2-3 hours        |
+| **Total**                       | **14-20 hours**  |
+
+---
+
+## Rollback Plan
+
+If issues arise after deployment:
+
+1. **Messages are preserved** - Content column still has plaintext for v1, migration preserves decrypted content
+2. **Re-enable E2EE** - Git revert the client changes
+3. **No data loss** - The migration only adds data (decrypts), doesn't delete
+
+---
+
+## Open Questions
+
+1. **Timeline**: When to execute the migration? During maintenance window?
+2. **Notification**: Should users be notified about the security model change?
+3. **Privacy Policy**: Does the privacy policy mention E2EE? May need update.
+4. **App Store**: Any App Store claims about E2EE that need updating?
