+# AISSIA - AI Smart Schedule & Interactive Assistant
+
+**AISSIA** is an intelligent personal assistant for time management, hyperfocus detection, and language learning, powered by **GroveEngine**.
+
+## What is AISSIA?
+
+AISSIA helps manage:
+- **Hyperfocus**: Detects when you've been working too long and need a break
+- **Time Management**: Intelligent scheduling and task planning
+- **Language Learning**: Interactive practice in target languages
+- **Notifications**: Context-aware alerts with TTS support
+
+## Built on GroveEngine
+
+AISSIA leverages **GroveEngine**, a C++17 hot-reload module system that enables:
+
+- **Hot-Reload**: Modify code at runtime without losing state (<1ms reload latency)
+- **Modular Architecture**: Self-contained modules (200-300 lines each)
+- **Pub/Sub Communication**: Decoupled inter-module messaging
+- **State Preservation**: Automatic state serialization across reloads
+- **Configuration Hot-Reload**: Update settings without code changes
+
+### Why GroveEngine?
+
+✅ **Ultra-fast Development**: Hot-reload validated at 0.4ms
+✅ **Type Safety**: Strong C++ typing, no "wildcode"
+✅ **Proven Architecture**: Production-ready module system
+✅ **Privacy-First**: Local mode, data never uploaded
+✅ **Progressive Evolution**: MVP → Production → Cloud without rewrite

+- Task estimation and tracking
+
+**NotificationModule**: System alerts with priority levels
+- Priority-based notifications (LOW, NORMAL, HIGH, URGENT)
+- Silent mode (respects URGENT priority)

+
+## Getting Started
+
+### Prerequisites
+
+- CMake 3.20+
+- C++17 compiler (GCC/Clang)
+- GroveEngine (included via symlink)
+
+### Build
+
+```bash
+# Configure
+cmake -B build
+
+# Build everything
+cmake --build build -j4
+
+# Build modules only (for hot-reload workflow)
+cmake --build build --target modules
+
+# Run
+./build/aissia
+```
+
+### Hot-Reload Workflow
+
+1. Start AISSIA: `./build/aissia`
+2. Edit a module: `src/modules/SchedulerModule.cpp`
+3. Rebuild: `cmake --build build --target modules`
+4. **Module reloads automatically with state preserved**
+
+### Configuration
+
+Configuration files in `config/`:
+
+**scheduler.json**:
+```json
+{
+    "hyperfocusThresholdMinutes": 120,
+    "breakReminderIntervalMinutes": 45,
+    "breakDurationMinutes": 10,
+    "workdayStartHour": 9,
+    "workdayEndHour": 18
+}
+```
+
+**notification.json**:
+```json
+{
+    "language": "fr",
+    "silentMode": false,
+    "ttsEnabled": false,
+    "maxQueueSize": 50
+}
+```
+
+## Documentation
+
+- **[docs/README.md](docs/README.md)**: Project documentation and architecture
+- **[docs/GROVEENGINE_GUIDE.md](docs/GROVEENGINE_GUIDE.md)**: Complete GroveEngine user guide
+- **[CDCDraft.md](CDCDraft.md)**: Detailed requirements specification (French)
+
+## Development Philosophy
+
+### MVP-First
+
+- **Phase 1 (Required)**: Local Windows mode only
+- **Phase 2+ (Optional)**: Cloud features if needed
+- **Configuration-Driven**: 90% of needs via JSON
+- **Simplicity First**: Complexity emerges from interaction
+
+### Module Development
+
+Each module is a self-contained unit (~200-300 lines):
+
+1. Implements `IModule` interface
+2. Pure business logic (no infrastructure code)
+3. Communicates via `IIO` pub/sub
+4. Serializes state for hot-reload
+5. Configurable via `IDataNode`
+
+See `docs/GROVEENGINE_GUIDE.md` for detailed module development guide.
+
+## Architecture
+
+AISSIA runs on a simple loop (10Hz for assistant workload):
+
+```
+┌─────────────────────────────────────────────┐
+│           Main Loop (10Hz)                   │
+│                                              │
+│  ┌────────────────────────────────────┐    │
+│  │  1. Check for module file changes   │    │
+│  │  2. Hot-reload if modified          │    │
+│  │  3. Process all modules             │    │
+│  │  4. Route inter-module messages     │    │
+│  │  5. Sleep to maintain 10Hz          │    │
+│  └────────────────────────────────────┘    │
+└─────────────────────────────────────────────┘
+```
+
+Modules communicate via topics:
+- `scheduler:hyperfocus_detected` → NotificationModule alerts user
+- `notification:alert_sent` → DataModule logs event
+- `aiassistant:suggestion` → NotificationModule displays suggestion
+
+## Technical Stack
+
+- **Core**: C++17
+- **Module System**: GroveEngine
+- **Logging**: spdlog
+- **Data Format**: JSON (nlohmann/json)
+- **Build**: CMake 3.20+
+- **Future**: SQLite (DataModule), Claude API (AIAssistantModule)

+## Architecture Technique
+
+### Principe Fondamental : Architecture Modulaire WarFactory
+
+L'architecture s'inspire de GroveEngine et suit le principe WarFactory :
+- **Hot-reload** : 0.4ms de latence de rechargement
+- **Modules ultra-compacts** : 200-300 lignes maximum
+- **Build autonome** : Chaque module se compile indépendamment
+
+### Hiérarchie du Système
+
+```
+MainServer Process
+├── CoordinationModule
+│   └── Charge appconfig.json
+├── DebugEngine
+│   └── SequentialModuleSystem
+└── Modules (.dll)
+    ├── scheduler.dll
+    ├── ai-assistant.dll
+    ├── language.dll
+    ├── notification.dll
+    └── data.dll
+```
+
+### Les 5 Interfaces Fondamentales
+
+```cpp
+ICoordinationModule  // Orchestrateur global du système
+    ↓
+IEngine             // DebugEngine → HighPerfEngine (évolution)
+    ↓
+IModuleSystem       // Sequential → Threaded → Cluster (évolution)
+    ↓
+IModule             // Logique métier pure (200 lignes max)
+    ↓
+IIO                 // IntraIO → LocalIO → NetworkIO (évolution)
+```
+
+## Contraintes Architecturales CRITIQUES
+
+### Règles pour les Modules
+
+**Caractéristiques obligatoires** :
+- ✅ 200-300 lignes maximum par module
+- ✅ Logique métier pure (pas de threading, pas de network)
+- ✅ Communication JSON uniquement entre modules
+- ✅ Build autonome : `cmake .` depuis le répertoire du module
+
+**Interdictions strictes** :
+- ❌ `cmake ..` ou `#include "../"` (pas de dépendances parent)
+- ❌ Modules dépassant 300 lignes
+- ❌ Dépendances directes entre modules
+
+**Principes de design** :
+- ✅ Build autonome garanti
+- ✅ Communication JSON standardisée
+- ✅ Hot-reload ready (rechargement à chaud)
+- ✅ Task-centric design (orienté tâches)
+
+### Workflow de Développement
+
+```bash
+# Développement d'un module
+cd modules/scheduler/
+cmake .                  # JAMAIS cmake ..
+make
+./scheduler-test
+
+# Edit SchedulerModule.cpp → Save → Hot-reload automatique en 0.4ms
+```
+
+## Communication Inter-Modules
+
+### Format JSON Standardisé
+
+Tous les modules communiquent exclusivement via messages JSON :
+
+```json
+// Détection d'hyperfocus → AIAssistantModule
+{
+  "event": "hyperfocus",
+  "duration_minutes": 120
+}
+
+// AIAssistantModule → NotificationModule
+{
+  "type": "break_suggestion",
+  "message": "Pause ?"
+}
+
+// NotificationModule → Système
+{
+  "notification": "system_toast",
+  "tts": true
+}
+```
