**IPIS (InterPlanetary Identity System)** is a voluntary protocol for identification, access control, and navigation in the Solar System. Its codename is **Duranki** (ancient Sumerian for *The Bond of Heaven and Earth*).
> **IPIS is not just a design system — it is a socio‑technical operating system.**
> Rockets are hardware. IPIS is the software that enables different people, nations, and machines to work together without conflict.
IPIS gives every object (human, spacecraft, robot) a **human‑readable code** and a **stackable history of visited worlds** – the **Snezhkov Stack**.
It does not replace national flags or existing systems (NORAD, transponders). It works alongside them, creating a shared semantic layer for space activities.

## Key Features
- **Simple coding** – circle (human/base), hexagon (robot), numbers 01 (Earth), 02 (Moon), 03 (Mars), indices `'` (orbit), `E` (EVA), `00` (deep space).
- **Snezhkov Stack** – horizontal row of touching small discs, each with a world number. First disc = birthplace, then work locations (>6 months). `E` disc after any world where EVAs were performed.
- **Ship Thread** – straight line on the hull from start to end node (e.g. `01—03`). Intermediate manoeuvres are digital only.
- **Two‑layer patch** – outer layer shows current code; under it hides a flat disc (future stack element). When you leave a base, the outer layer is peeled off and the disc is added to your stack. No need to print new patches in space.
- **Ritual “Base Gulp”** – a glass of local water, a sip, the sound of Velcro – a symbolic admission into the new ecosystem.
- **Technical integration** – RFID chips in patches for access control; `IPIS_CODE` field in NORAD / Space‑Track.org catalog. Stack verification is based on ship and base logbooks (digitally signed).

## Quick Example
A person born on Earth (`01`), who worked on a lunar orbital station with EVAs (`02’E`), and is currently on Mars (`03`):
- **Main patch:** circle with `03`
- **Stack:** `01` `02’` `E`
- **Two‑layer mechanism:** when leaving the lunar station, the outer `02’` patch was peeled off and the inner disc `02’` (plus the `E` disc earned there) became part of the stack.

A picture is worth a thousand words. See how IPIS looks on a Martian suit, a spacecraft hull, and in mission control.

## How to Use This
1. **Quick start** – [Quick Start for Beginners](docs/quickstart.md) – make your first IPIS patch in 5 minutes.
2. **Read the presentation** – [Slides](presentation/slides.md) (convert to PDF for printing).
3. **Learn the stack mechanics** – [Stack Guide](docs/stack_guide.md) for detailed patch donning / updating.
4. **Dive into technical integration** – [RFID spec](docs/rfid_spec.md) and [NORAD extension](docs/norad_extension.md).
5. **Explore cultural examples** – [Stack Examples](docs/stack_examples.md) (Major Tom, John Carter, etc.).
The system is **open** – you can adopt, modify, and pilot it. Feedback and contributions are welcome.
