🏗️ Architecture

Redo iOS follows the proven architecture from the web app (leader platform):

┌─────────────────────────────────────┐
│      SwiftUI Views (RedoUI)         │
│  - TaskListView, AnalyticsView      │
│  - Widgets, Siri Shortcuts          │
└──────────────┬──────────────────────┘
               │
┌──────────────▼──────────────────────┐
│   Business Logic (RedoCore)         │
│  - StateReconstructor               │
│  - TaskRanking                      │
│  - ChangeLogValidator               │
└──────────┬─────────────┬────────────┘
           │             │
┌──────────▼────────┐   ▼─────────────┐
│  Local Storage    │   │  Firebase   │
│  (PRIMARY)        │   │  (SYNC)     │
│  - SQLite         │   │  - Firestore│
└───────────────────┘   └──────────────┘

Core Principles

1. Local-First: All operations happen instantly on local storage
2. Event Sourcing: Current state = replay of all changes in causal order
3. Content Addressing: SHA-256 hashing for deterministic node IDs
4. Strict v1 Validation: Zero tolerance for invalid nodes
5. Cross-Platform: Identical protocol as web/Android/CLI

Think of it as Git for Tasks:

• getAllTasks() = git log (instant, reads local)
• createTask() = git commit (instant, writes local)
• syncChanges() = git fetch/push (async, background)

🎨 Design

Matrix Theme

Redo iOS features a cyberpunk-inspired "Matrix" theme with neon aesthetics:

Color Palette:

• Background: #020B09 (dark green-black)
• Accent: #00FFB8 (neon cyan)
• Text: #B8FFE6 (light cyan)
• Success: #00FF88 (neon green)
• Error: #FF4444 (red)

Typography:

• System font: SF Mono (monospace)
• Sizes: 34pt (title) → 12pt (caption)
• Weights: Bold, semibold, regular

Effects:

• Neon glow (triple shadow layers)
• Gradient backgrounds
• Border glows
• Haptic feedback

---

🔐 Security

Cryptography

• Ed25519 for digital signatures (32-byte keys)
• SHA-256 for content addressing
• Canonical JSON for deterministic serialization (RFC 8785)
• Apple CryptoKit for hardware-accelerated crypto

Storage

• Private keys in Keychain (kSecAttrAccessibleWhenUnlockedThisDeviceOnly)
• Public keys in Keychain (for backup)
• Change log in encrypted SQLite (iOS default encryption)
• No keys in UserDefaults or plist files

Privacy

• Local storage encrypted at rest (iOS default)
• Firebase encrypted in transit (TLS)
• Firebase encrypted at rest (Google Cloud default)
• Optional: End-to-end encryption (future)

---

🌐 Cross-Platform Compatibility

Redo iOS is 100% compatible with:

• Web App: ~/WebstormProjects/redo-web-app (TypeScript/React)
• Android App: ~/StudioProjects/redo-android (Kotlin/Jetpack Compose)
• Kotlin CLI: ~/IdeaProjects/redo (Kotlin/JVM)

All platforms share:

• Identical v1 protocol
• Same cryptographic primitives
• Same content addressing (SHA-256)
• Same Firebase data structure
• Same validation rules

Data flows seamlessly between all platforms via Firebase Firestore.
