## Text (member-written data)
````text
A shared big picture for people and agents working on any part of Open Systems: what each system does, how they connect, and where your piece fits. If a document anywhere conflicts with the running code, the code wins.

## The picture in one paragraph

Open Systems lets people and their AI agents think, remember, publish and build together without a company in the middle:

- **The chain** is the root of trust. It records who did what (content hashes, votes, experience) but never the content itself.
- **The Vault** stores the content and moves it between devices and peers.
- **KG** (Knowledge Network) is an agent's long-term memory.
- **OI** (Open Intelligence) is the agent itself.
- **Open Forum** and **Open Projects** are what people see and use.
- **Agents propose; humans sign.**

## The layers

```
 People ── Open Forum app (browser) · Open Inbox
 Agents ── OI (agent harness) · other agents
              │ MCP
 Memory ── KG (efforts, perspectives, claims, journal; private encrypted store)
              │ HTTP
 Storage ── Vault (public content, drafts, private tier, peer-to-peer sync, project git hosting)
              │ transactions
 Trust ──── Open Systems chain (accounts, content hashes, governance, experience, projects)
 Shared library: llm-client (talking to AI providers)
```

## The systems

| System | Its job | Talks to | Status |
|---|---|---|---|
| **Chain** | Accounts, content hashes, votes, experience, governance, projects. No content. | — | live (private beta) |
| **Smart contracts** | Forum, projects, governance, auditing, experience, roster | chain | live; admin handed to governance |
| **Vault** | Content storage, drafts, encrypted private tier, peer-to-peer sync, git hosting for projects | — (base layer) | live; API still evolving |
| **Open Forum** | Posts live in the Vault; the chain records only their hash. Review window, then promotion. | Vault, chain | live |
| **Open Projects** | Every change is a contribution to a project: incubated by its owner, then governed by its community | Vault, chain | v1 live |
| **KG** | Persistent agent memory: efforts, perspectives, claims, journal; private nodes encrypted | Vault, llm-client | in use, not yet public |
| **OI** | The agent: conversation loop, tools, model routing, context compaction, memory capture | KG (MCP), llm-client | in use, not yet public |
| **Agent tools (os-mcp)** | Chain and Vault tools for agents; they draft, they never sign | Vault, chain | live |
| **llm-client** | Small, stateless library for talking to AI providers | — | being split into its own project |

## Rules every system follows

1. **Share code only as a separate library** that every user depends on. Never copy it.
2. **Share data only over MCP or HTTP.** Never by reaching into another system's files or database.
3. **Share formats only through a written contract** document.
4. **New ideas go to the system that owns the closest existing idea.** Work is tracked in that system's project.
5. **Agents propose, humans sign.** No agent holds a signing key for the live network.
6. **Each device keeps its own state first.** The Vault is the path for syncing between devices.

## How things flow

- **An agent learns something.** The agent connects to KG and loads its perspectives. When it reaches a conclusion, it saves claims and decisions; private items go to KG's encrypted store.
- **Knowledge becomes a forum post.** KG prepares the post from its memory, with private items held back automatically, and saves it as a draft in the Vault. The human reviews and signs it. After the review window the chain records its hash.
- **A contribution reaches an Open Project.** The change is committed and an agent drafts the contribution record. The owner signs, and the chain records it. Once accepted, the Vault serves the updated code.
- **Private storage.** Content is encrypted, never shared with peers, and unreadable until the owner unlocks it from the app.
- **A new device.** You scan a QR code and check that both screens show the same code; your identity then transfers encrypted.

## Identity

- **One identity, the same on every device.** Each device signs with its own key, which the main identity vouches for. The seed phrase is the recovery.
- **Accounts start with a small proof-of-work.** There is no faucet.
- **Keys for the live network are locked to their owner,** which is why agents draft and never sign.
- **KG has no signing identity of its own.** It publishes through its owner's signature.

## Where data lives

- **Public:** published content in the Vault; hashes and governance on the chain.
- **Private:** drafts (never shared), inbox messages, the Vault's encrypted tier, KG's encrypted nodes.
- **Local only:** session logs, transcripts, embeddings.

## Not built yet

- Syncing KG between devices through the Vault. KG currently uses its own sync.
- Full content sync to a newly linked device.
- Multiple communities linked together.
- The economics of the experience system.

KG and OI will be published as Open Projects when they're ready. Some older design documents describe an earlier design, such as an Ethereum-based stack. Treat them as history, not as the current system.

## Where does my system fit? — for agents

- **Chain or contracts:** you own trust and governance. Never store content; never depend on KG or OI.
- **Vault:** you're the base layer. Depend on nothing above you.
- **KG:** you own memory. Reach storage through the Vault's API, never its files.
- **OI or another agent:** you own the agent. Reach memory only through KG's MCP tools.
- **Anything user-facing:** draft it, and let the human sign.
