About SpaceCorps

SpaceCorps is a high-performance systems engineering collective dedicated to building ultra-fast native software in pure Rust: autonomous agent developer tooling, real-time 3D simulation engines, and atomistic scientific computing suites. We bridge human operators, autonomous AI coding agents, and computational physics with zero runtime bloat.

The Two Pillars of SpaceCorps

1. Autonomous Agent CLI Fleet

Modern developer tools are weighed down by heavy interpreted runtimes (.NET, Python, Node.js) that incur hundreds of megabytes of disk overhead and hundreds of milliseconds of startup latency. When autonomous AI agents fan out concurrently to inspect, deploy, and verify infrastructure, these startup delays cripple agent responsiveness.

Originally prototyped as .NET global tools by developer Niels Bosma, the entire fleet was acquired and completely re-architected in 2026 into native Rust 2024 binaries under the SpaceCorps organization. Each tool preserves the full original git history while upgrading the implementation to modern systems engineering standards: single static binaries, blocking HTTP with rustls, native operating system keystore encryption, and deterministic YAML/JSON outputs.

2. Space3d Ecosystem & Scientific Physics Simulation

SpaceCorps engineers next-generation simulation and graphics systems in pure Rust (edition 2024, no C/C++/Fortran/Python dependencies, no FFI):

• Space3d Engine: A modular cross-platform 3D game and simulation engine built on wgpu 30 and winit. Featuring a deterministic 60 Hz fixed tick ECS (hecs), a GPU-driven indirect draw renderer capable of drawing 1,000,000+ instances in a few draw calls, non-blocking async asset streaming, SQLite persistence, and visual regression testing in cargo test.
• spacemd (Molecular Dynamics): Simulates atomic interactions and reports thermodynamic properties at up to 74M–108M atom-steps/s on Apple M4 Max. Supports Lennard-Jones, Morse, Buckingham, Ewald Coulomb, and Embedded-Atom Method (EAM) potentials, with NVE, NVT, and NPT ensembles.
• spaceemit (Thermal-Field Electron Emission): Computes current density, Nottingham heat, and full energy distributions across field, thermionic, and intermediate regimes with 14 µs per-point exact quantum transmission. Exposes both a Rust library and an OpenAPI 3.1 REST API server.
• molviewer: Real-time 3D simulation viewer with GPU-instanced atoms, live energy plots, and thermostat controls, running natively on the Space3d engine.

On-device game AI: alongside the two Rust pillars, SpaceCorps maintains two MIT-licensed libraries in other languages: OpenAppleModels (Swift, Apple Foundation Models) and OpenAndroidModels (Kotlin, Gemini Nano; not yet run on a Gemini Nano device), both pre-release. They are built to give games NPC dialogue with tool calls, AI decisions and content generation on the device, without a cloud service. Both speak the same JSON-RPC 2.0 protocol (v1.0), so a game engine such as Space3d can implement it once and inject the Apple backend (C ABI) or the Android backend (JNI) per platform.

The SpaceCorps Engineering Tenets

• Pure Native Rust 2024: Zero garbage collection pauses, memory safety guarantees, and sub-3ms execution startup for instantaneous terminal response.
• Deterministic Protocols: Human-readable YAML on standard output by default, strict structured JSON when passed --json, and machine-readable error envelopes on standard error with stable exit codes (1 to 7).
• Rigorous Physics Validation: Liquid argon self-diffusion matches experiment (2.43–2.55 × 10⁻⁵ cm²/s); NaCl Madelung constant computed to 1.74756459; forces match energy gradients to relative error ≤ 4 × 10⁻⁸; electron emission energy spectra sum rules hold to ≤ 5 × 10⁻⁴.
• Cryptographic OS Keystores: No unencrypted tokens or plaintext credentials in home directories. Keys are securely stored via macOS Keychain Services, Linux Secret Service, or Windows DPAPI.
• 100% Offline TCP Mock Integration Testing: Every CLI command is verified by in-process TCP mock servers, ensuring zero flaky network tests and rock-solid deterministic CI/CD pipelines.
• Autonomous Agent Discovery: Every tool publishes dedicated llms.txt manifests, agent cards, and embedded <binary> agent-readme commands so AI agents can self-configure and operate independently.
