CodeArena Core: The Engine Stack 🏛️

Organization: github.com/codearena-platform

High-performance, mission-critical infrastructure for the CodeArena ecosystem. This repository contains the physics engine, real-time broadcasting, and execution runtime that power industrial-grade bot combat.

Key Modules

The Core is a unified Go module github.com/codearena-platform/core:

• pkg/types: The "Source of Truth" for the entire network layer.
• internal/simulation: The Match-Making and Physics engine (Deterministic Combat).
• internal/realtime: Low-latency WebSocket broadcasting for battle state.
• internal/runtime: Bot sandboxing and isolation layer.

Concurrency & Scaling

CodeArena Core is designed for extreme horizontal and vertical scaling.

While influenced by the performance patterns of Rust's Tokio, CodeArena Core leverages the native Go Goroutine Scheduler to manage thousands of concurrent battle processes across multiple threads with microscopic memory footprint.

• M:N Scheduling: Millions of logical tasks mapped to a small pool of OS threads.
• Work-Stealing: Dynamic task distribution across CPU cores to prevent bottlenecks.
• Non-Blocking I/O: High-concurrency WebSocket and gRPC handled via efficient epoll/kqueue abstractions.

Modular Integration

This repository supports two primary modes of operation:

1. Standalone Microservices: Each module can be built as a separate binary via cmd/.
2. Unified Core Daemon: Use cmd/core/main.go to launch all core services within a single high-performance process, managed by internal Goroutine workers.

Building

# Build the integrated core
go build -o codearena-core ./cmd/core/main.go

# Build specific standalone services
go build -o sim ./cmd/sim
go build -o rt ./cmd/rt

Standalone Usage

This repository is fully decoupled. To use core types in other repositories:

go get github.com/codearena-platform/core/pkg/types

CodeArena Core is the primary engine stack of the CodeArena-Platform.
