Complete Phase 1: Finalize all core interfaces with immutable architecture
- **IEngine**: Add run(), step(), loadModules(), socket management, health monitoring - **IModuleSystem**: Inherit ITaskScheduler, 1:1 module relationship, task delegation - **IModule**: Service injection (IIO*, ITaskScheduler*), pub/sub communication, void process() - **IIO**: Pull-based pub/sub with wildcards, low-frequency batching, health monitoring - **ITaskScheduler**: Task delegation interface for module→execution system Architecture completed with quadruple interface pattern optimized for: - Thread-safe pull-based messaging - Module task delegation to execution systems - Engine health monitoring of all IIO instances - Immutable interface foundation for future development 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

## Key Technical Concepts
|
||||
|
||||
### Modular Architecture (PRODUCTION-READY)
|
||||
- **Triple Interface Pattern**: IEngine, IModuleSystem, IModule(`process()`, `initialize()`, `shutdown()`), IIO
|
||||
### Core Interface Architecture (COMPLETED - PHASE 1)
|
||||
- **Quadruple Interface Pattern**: IEngine, IModuleSystem, IModule, IIO + ITaskScheduler
|
||||
- **CRITICAL**: **Core interfaces are IMMUTABLE** - Never modify once finalized
|
||||
- **Autonomous Modules**: Small (200-300 lines) hot-reloadable modules (.so files)
|
||||
- **Claude Code Optimized**: Each module is a micro-context for AI development
|
||||
- **Performance Targets**: V1 Client 30+ fps, V2 Client 60+ fps, V1 Server 10+ players, V2 Server 100+ players
|
||||
- **570+ Specifications**: Complete technical catalog in INTEGRATION-MASTER-LIST.md
|
||||
|
||||
### Interface Specifications (NEVER MODIFY THESE)
|
||||
- **IEngine**: Engine orchestration, module loading, client/coordinator socket management
|
||||
- **IModuleSystem**: Execution strategy + task scheduling (inherits ITaskScheduler)
|
||||
- **IModule**: Pure business logic + pub/sub communication + task delegation
|
||||
- **IIO**: Pull-based pub/sub with low-frequency batching and health monitoring
|
||||
- **ITaskScheduler**: Task delegation interface for module → execution system
|
||||
|
||||
### Module Frequencies & Isolation
|
||||
- **ProductionModule**: 60Hz (frame-perfect factory operations)

## Development Context
|

|
||||
### Current Status
|
||||
- **Phase**: **PRODUCTION-READY** - Modular architecture fully specified
|
||||
- **Build System**: Module-based CMake with autonomous builds per module
|
||||
- **Development Ready**: Hot-reload modules, 5-second iteration cycles
|
||||
- **Integration**: 85% complete (487/570 specifications integrated)
|
||||
- **Next Steps**: Module implementations (TankModule, EconomyModule, FactoryModule)
|
||||
- **Phase**: **INTERFACES COMPLETE** - All core interfaces finalized and production-ready
|
||||
- **Core Architecture**: 4 interfaces completed with full specifications
|
||||
- **Development Ready**: Hot-reload modules, pub/sub messaging, task delegation
|
||||
- **Integration**: Interface design phase complete (Phase 1 TODO finished)
|
||||
- **Next Steps**: Phase 2 - Initial implementations (DebugEngine, SequentialModuleSystem, IntraIO)

## Module Constraints (CRITICAL)
|
||||
|
||||
### NEVER/ALWAYS Rules
|
||||
- **INTERFACE STABILITY**: NEVER modify core interfaces - only implement them
|
||||
- **NEVER `cd ..`**: Jamais référence directories parent modules
|
||||
- **ALWAYS `cmake .`**: Builds autonomes par module (NEVER cmake ..)
|
||||
- **NEVER `#include "../"`**: Isolation modules stricte
|
||||
- **ONLY JSON Communication**: Communication entre modules via JSON uniquement
|
||||
- **PUB/SUB Communication**: Communication via IIO publish/subscribe only
|
||||
- **TASK DELEGATION**: Use ITaskScheduler for module → execution system tasks
|
||||
- **ZERO Infrastructure Code**: Aucun code infrastructure dans contexts modules

## Claude Code Development Practices

|
||||
### Interface Management (ABSOLUTELY CRITICAL)
|
||||
- **IMMUTABLE INTERFACES**: Core interfaces (IEngine, IModuleSystem, IModule, IIO, ITaskScheduler) are FROZEN
|
||||
- **NEVER MODIFY**: Once interfaces are finalized, they become the architectural foundation
|
||||
- **Extension Only**: New functionality via new implementations, not interface changes
|
||||
- **Breaking Changes**: Modifying core interfaces breaks ALL existing modules and systems
|
||||
- **Documentation**: Interface changes require complete system redesign - avoid at all costs
|
||||
|
||||
### Context Management (CRITICAL)
|
||||
- **Small Modules**: Compact modules for focused development (micro-contexts)
|
||||
- **Context Optimization**: Massive context reduction through modular design

|
||||
## ✅ Phase 1: Core Interfaces 🏗️ - COMPLETED
|
||||
|
||||
### Interface Definitions
|
||||
- [ ] **IEngine.h** - Engine orchestration interface
|
||||
- `initialize()`, `update(deltaTime)`, `shutdown()`
|
||||
- `setModuleSystem(std::unique_ptr<IModuleSystem>)`
|
||||
### Interface Definitions - ALL COMPLETE ✅
|
||||
- ✅ **IEngine.h** - Engine orchestration interface
|
||||
- `initialize()`, `run()`, `step()`, `shutdown()`
|
||||
- `loadModules(configPath)` - Automatic module loading with strategies
|
||||
- `registerMainSocket()`, `registerNewClientSocket()` - Priority channels
|
||||
- `getType()` - Engine type identification
|
||||
- **IIO health monitoring** - Engine monitors all module IIO health
|
||||
|
||||
- [ ] **IModuleSystem.h** - Module execution strategy interface
|
||||
- `registerModule(name, std::unique_ptr<IModule>)`
|
||||
- `processModules(deltaTime)`, `setIOLayer(std::unique_ptr<IIO>)`
|
||||
- `queryModule(name, json input) -> json`
|
||||
- ✅ **IModuleSystem.h** - Module execution strategy + task scheduling
|
||||
- Inherits from `ITaskScheduler` for task delegation
|
||||
- 1:1 module relationship with `setModule()`, `getModule()`
|
||||
- `processModule(deltaTime)` returns int error code
|
||||
- `getType()` - ModuleSystem type identification
|
||||
- Task scheduling: `scheduleTask()`, `hasCompletedTasks()`, `getCompletedTask()`
|
||||
|
||||
- [ ] **IModule.h** - Pure business logic interface
|
||||
- `json process(const json& input)` // PURE FUNCTION
|
||||
- `initialize(const json& config)`, `shutdown()`
|
||||
- `getState()`, `setState(const json& state)` // Hot-reload support
|
||||
- ✅ **IModule.h** - Pure business logic + pub/sub + task delegation
|
||||
- `initialize(config, IIO*, ITaskScheduler*)` - Service injection
|
||||
- `void process(input)` - Void return, uses pub/sub for communication
|
||||
- `getState()`, `setState()` - Hot-reload support
|
||||
- `getType()` returns string - Module identification
|
||||
- Full access to IIO pub/sub and ITaskScheduler delegation
|
||||
|
||||
- [ ] **IIO.h** - Communication transport interface
|
||||
- `json send(target, message)`, `json receive(source)`
|
||||
- `broadcast(const json& message)`
|
||||
- ✅ **IIO.h** - Pull-based pub/sub with health monitoring
|
||||
- `publish(topic, message)` - Topic-based publishing
|
||||
- `subscribe(topicPattern, config)` - High-frequency subscription with wildcards
|
||||
- `subscribeLowFreq(topicPattern, config)` - Low-frequency batched subscription
|
||||
- `hasMessages()` returns count, `pullMessage()` consumes messages
|
||||
- `getHealth()` - Health metrics for Engine monitoring
|
||||
- `getType()` - IO type identification
|
||||
|
||||
- ✅ **ITaskScheduler.h** - Task delegation interface (defined in IModule.h and IModuleSystem.h)
|
||||
- `scheduleTask(taskType, taskData)` - Delegate tasks to execution system
|
||||
- `hasCompletedTasks()` returns count, `getCompletedTask()` pulls results
|
||||
- Implemented by IModuleSystem for different execution strategies
|
||||
|
||||
**CRITICAL**: All interfaces are now IMMUTABLE - Never modify these core interfaces!
