A low-weight 2D-engine (visually 3D) astronomy simulator that renders only proven celestial objects through a deterministic universe graph. Portable offline client with catalog-driven truth packs, orbit visualization, and scalable galaxy-to-planet navigation.
🔐 Built on ARC-Core — the authority / event / receipt kernel. Every celestial object, orbit derivation, and scale-tier transition is an ARC-Core-shaped event with provenance-checked receipts. The "NASA Standard" qualifier is enforced by ARC-Core's authority-over-provenance contract.
Neo-VECTR is a deterministic astronomy simulator built around truth packs — catalog-driven manifests of celestial objects whose provenance (observation catalog, identifier, instrument, epoch) is cryptographically verifiable. The simulator will not render an unverified object. If a truth pack says "this planet exists with these orbital parameters from this NASA-standard source," that claim is receipt-backed.
- NASA-standard ingestion — only celestial objects traceable to a canonical catalog are accepted
- Truth packs — self-contained, SHA-256-verifiable bundles of astronomical data
- Deterministic rendering — two users with the same truth pack see the same universe bit-for-bit
- Offline-first — full operation without a network once truth packs are local
- Low-weight — 2D math core projected to 3D visually; runs on modest hardware
- Scalable navigation — galaxy → system → planet tier transitions without reloading
Neo-VECTR uses the ARC-Core authority kernel for:
| Neo-VECTR layer | ARC-Core pattern |
|---|---|
| Truth-pack receipt chain | Every celestial object has a provenance receipt citing its NASA-standard source |
| Event-sourced navigation | Camera, zoom, pan, scale-tier transitions are events; any viewport is reconstructable by replay |
| Authority over "proven" | The NASA-standard qualifier is an authority claim backed by proposal → evidence → receipt flow |
| Deterministic universe-graph replay | Universe graph is derived from truth packs + event log; fully reproducible |
| Offline verification | Receipts are SHA-256-addressable; packs verifiable without a server |
| Object identity | ARC-Core's entity-resolution pattern applied to celestial objects across truth packs |
Neo-VECTR is one of several consumer applications built on the ARC governed-AI ecosystem. All share the same author and the same event-and-receipt doctrine:
- ARC-Core — authority / event / receipt kernel (backbone of this project)
- arc-cognition-core — model-growth lab
- ARC-Neuron-LLMBuilder — governed AI build loop
- arc-language-module — governed lexical truth
- omnibinary-runtime — binary mirror / runtime ledger
- Arc-RAR — archive / rollback bundles
- arc-lucifer-cleanroom-runtime — deterministic operator kernel
Companion consumer repos:
- Seeded-Universe-Recreation-Engine — the broader seeded-universe research project
- Proto-Synth_Grid_Engine — the Synth grid runtime
- RiftAscent — action game on the same backbone
- TizWildinEntertainmentHUB — audio plugin ecosystem
