Warfactory - Implementation Roadmap

Current Status

✅ Phase 1 Complete: Core Interfaces (IEngine, IModuleSystem, IModule, IIO, ITaskScheduler) ✅ Phase 2 Complete: BLAZING HOT-RELOAD SYSTEM - 0.4ms average reload time! 🚀 Current Phase: Phase 3 - Module Ecosystem Development

---

✅ Phase 1: Core Interfaces 🏗️ - COMPLETED

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 + 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 + 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 - 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!

• Hot-reload ready: Always implement getState()/setState()

Performance Targets

• V1 Client: 30+ fps
• V2 Client: 60+ fps
• V1 Server: 10+ players
• V2 Server: 100+ players
• Iteration cycle: <5 seconds (edit → reload → test)

Testing Strategy

• #ifdef TESTING validation in modules
• Standalone testing: Test modules without full engine
• AI-optimized: Simple tests for Claude Code development
