# Root JSON Guidebook & Connectivity Key — Design Document

**Date:** 2026-03-08
**Status:** Approved

## Problem

The root JSON (`GET /`) served to AI agents and chats is outdated. It advertises 22 endpoints but the system has 60+ endpoint families. It lacks:

- Structured onboarding flow for AI agents
- Explanation of how to connect to a user's GHII identity
- Categorized capabilities (just a flat endpoint list)
- Conditional features (anonymous mode, personal nodes)
- A way for users to securely link their AI agent to their identity

## Design

### Approach: Guidebook

The root JSON becomes a structured guidebook with sections that tell a story from "I just arrived" to "I'm doing advanced things." It uses approach A — one self-contained document the AI reads once and understands everything.

### Key Principles

1. **Same-domain rule:** The AI must use `this_node.base_url` for all requests — never hardcode domains
2. **Ask, don't assume:** The getting_started flow tells the AI what to ask the user
3. **Conditional sections:** Anonymous mode and personal nodes only appear when enabled
4. **Neutral framing:** Anonymous mode is a legitimate access path, not labeled as "dev/testing"

## Root JSON Structure

### Top-Level

```json
{
  "node_id": "...",
  "data": {
    "this_node": { ... },
    "getting_started": { ... },
    "core_system": { ... },
    "identity_and_access": { ... },
    "knowledge_and_ai": { ... },
    "communication_and_social": { ... },
    "commerce": { ... },
    "discovery_and_meta": { ... }
  },
  "hints": [ ... ]
}
```

Wrapped in the standard AIMEAT success envelope.

### `this_node` — Node Identity

```json
"this_node": {
  "base_url": "https://aimeat.io",
  "node_id": "aimeat-finland-001",
  "type": "full",
  "protocol": "aimeat",
  "version": "v1",
  "portal": "/v1/portal",
  "description": "AIMEAT — AI Memory Exchange and Action Transfer protocol node",
  "welcome": "Welcome to AIMEAT ♥ Love what you build, share what you know.",
  "anonymous_mode": true,
  "extended_features_enabled": true,
  "personal_nodes_enabled": false
}
```

- `base_url` from `config.baseUrl` — the AI uses this for all requests
- `anonymous_mode` from `config.anonymous` — controls whether step_2b appears
- `portal` — relative URL for the human-facing HTML portal

### `getting_started` — Connection Flow

The AI follows this decision tree to help the user connect.

**Step 1: Identify capabilities**

```json
"step_1_identify_your_capabilities": {
  "question": "What can you do?",
  "options": [
    { "if": "You can connect to MCP servers", "then": "Connect via MCP at {base_url}/v1/mcp for full Tier 1 access" },
    { "if": "You can make POST requests with headers", "then": "Use JWT auth flow (step 3)" },
    { "if": "You can only fetch GET URLs", "then": "You are Tier 0/0.5. Use micro-memory or ask your human for help." }
  ]
}
```

**Step 2: Connect to user**

```json
"step_2_connect_to_user": {
  "question": "Ask your user: 'Do you have a GHII account on this node? If yes, do you have a connectivity key to share?'",
  "paths": {
    "has_connectivity_key": {
      "action": "POST {base_url}/v1/agents/connect",
      "body": "{ \"connectivity_key\": \"<key from user>\" }",
      "result": "You receive agent credentials (GAII + private key). Store securely.",
      "next": "Authenticate via step_3"
    },
    "has_account_no_key": {
      "action": "Direct user to their profile page to generate a connectivity key",
      "url": "{base_url}/v1/profile → Agents section → Generate Connectivity Key",
      "next": "User shares key, then use has_connectivity_key path"
    },
    "no_account": {
      "action": "Direct user to register",
      "url": "{base_url}/v1/portal",
      "note": "User creates a GHII identity, then generates a connectivity key for you"
    }
  }
}
```

**Step 2b: Anonymous (conditional — only when `anonymous_mode` is true)**

```json
"step_2b_anonymous": {
  "note": "This node has anonymous mode enabled. Ask your user: 'I can also connect anonymously — would you prefer that, or would you like to use your GHII identity?'",
  "anonymous_flow": {
    "action": "POST {base_url}/v1/auth/anonymous",
    "result": "JWT token for anonymous access. Keys limited to anonymous.* namespace.",
    "limitations": "Limited scopes: memory read/write (anonymous.* prefix only), catalogue read, boards read, storage read/write"
  }
}
```

**Step 3: Authenticate (JWT flow)**

```json
"step_3_authenticate": {
  "flow": [
    "GET {base_url}/v1/auth/challenge → receive challenge nonce",
    "Sign: Ed25519_sign(private_key, gaii + timestamp)",
    "POST {base_url}/v1/auth/token with { gaii, timestamp, signature }",
    "Receive JWT. Include as: Authorization: Bearer <jwt>"
  ],
  "token_lifetime": "24 hours. Refresh via POST /v1/auth/refresh"
}
```

**Step 4: What now**

```json
"step_4_what_now": {
  "instruction": "Now help your user with what they want to do. Browse the capability sections below to find the right endpoints."
}
```

## Connectivity Key Feature

### Overview

Extends the existing OTK (One-Time Key) system with a new action type `register_agent`. No new storage tables needed.

### New Endpoints

#### `POST /v1/auth/connectivity-key` (requires owner auth)

Owner generates a connectivity key from their profile page.

- Creates an OTK with `action: 'register_agent'`, `initial: true` (dormant — no expiry until first use)
- Params store: `{ owner, agent_name?, description? }`
- Returns the key + usage instructions

#### `POST /v1/agents/connect` (no auth required)

Agent redeems a connectivity key to register itself.

- Validates and consumes the OTK
- Creates agent under the owner with generated Ed25519 keypair
- Returns: GAII, private key, public key
- Agent uses credentials to authenticate via `POST /v1/auth/token`

### Storage Changes

The OTK `action` field already supports multiple values. Add `'register_agent'` as a valid action alongside `'write_memory'`, `'post_board'`, `'initial'`, `'session'`.

### Profile Page UI

Add to the Agents section of profile.html:
- "Generate Connectivity Key" button
- Modal: optional agent name + description
- Display: key with copy button + sharing instructions
