This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

**Warfactory** is a Factorio-inspired industrial military simulation game combining factory management with strategic military doctrine. The project is currently in design/documentation phase with comprehensive technical specifications.

**Core Philosophy:**
- Factory assembly lines as gameplay foundation
- Player-driven military doctrine development
- Progression from PMC operations to conventional warfare
- Choice and complexity balanced with accessible presentation

## Documentation Architecture

The project uses a modular documentation system in `/docs/`:

### Core Design Documents
- `vue-ensemble.md` - Vision, philosophy, and design principles
- `architecture-technique.md` - Multi-server architecture, engines, performance specs
- `systemes-techniques.md` - Tile system, memory management, chunks
- `map-system.md` - Procedural generation with 218+ elements, budget system (-10 to +10)

### Gameplay Systems
- `gameplay-industriel.md` - Resource flow, production, factory optimization
- `systeme-militaire.md` - Vehicle design with grid-based component placement
- `economie-logistique.md` - Market simulation, supply chains, pricing
- `mecaniques-jeu.md` - Research systems, breakthrough mechanics, administration

### Advanced Systems
- `arbre-technologique.md` - 3000+ technology tree with prerequisites gating
- `metriques-joueur.md` - Comprehensive analytics (3.1GB per game, adaptive scaling)
- `coherence-problem.md` - Resolved design contradictions and technical challenges

## Key Technical Concepts

### Engine Architecture
- **Autonomous Engines**: 6 specialized engines (Economy, War, Intelligence, Designer, MacroEntity, Map)
- **Smart Client**: Request/response pattern, no streaming, FOW at chunk granularity
- **Performance Target**: 60fps with 1000+ AI companies, 1-2 vehicle designs/tick globally

### Map System
- **Multi-scale**: World (diplomatic) → Regional (logistics) → Local (factory) → Detail (combat)
- **Procedural Generation**: 218 elements with budget scoring, millions of combinations
- **Chunk System**: 64x64 tiles, streaming on demand, persistent storage

### Military Design
- **Grid-based Vehicle Design**: Irregular chassis shapes with component placement
- **Interface**: Pick/place with A/E rotation, R for snap toggle, template support
- **Combat**: Multi-chunk battles, persistent frontlines, auto-battler with player oversight

## Development Context

### Resolved Issues
Most initial "coherence problems" (P1-P30) were invalidated through clarification:
- Architecture scales properly with smart resource management
- Interface complexity is standard for genre (comparable to Factorio, Tarkov inventory)
- Performance targets achievable with proper optimization
- Only P7 (engine responsibilities) requires further analysis

### Current Status
- **Phase**: Design documentation complete, technically viable
- **Next Steps**: Implementation planning, engine responsibility clarification
- **Questions Open**: 11 items in `questions-ouvertes.md` for future resolution

## Working with This Project

### Documentation Updates
- Cross-reference systems when making changes (especially architecture ↔ gameplay)
- Maintain coherence between technical specs and game design
- Update `coherence-problem.md` if new conflicts emerge

### Key Design Constraints
- **Skip-ability**: All systems must be automatable for accessibility
- **Depth vs Accessibility**: Complex systems with simple interfaces
- **Performance**: Real-time constraints with large-scale simulation
- **Realism**: Military authenticity balanced with gameplay fun

### Important Files for Context
- Start with `vue-ensemble.md` for project vision
- Reference `architecture-technique.md` for technical decisions
- Check `coherence-problem.md` for resolved design challenges
- Use `questions-ouvertes.md` for known open issues
