# GENOME.md — The Nexus Codebase Architecture Map
|
||||
|
||||
**Generated**: 2026-04-20
|
||||
**Repository**: Timmy_Foundation/the-nexus
|
||||
**Purpose**: Comprehensive map of the Nexus codebase for developers and AI agents.
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
The Nexus is Timmy's canonical 3D/world repository — a sovereign AI agent visualization surface and local-first training ground. It combines a Three.js 3D browser world with Python cognition components, WebSocket bridges, and fleet orchestration tools.
|
||||
|
||||
**Key Stats**:
|
||||
- ~357 source files
|
||||
- 201 Python files
|
||||
- 23 JavaScript files
|
||||
- 107 Markdown docs
|
||||
- 24 Shell scripts

|
||||
node --test tests/*.js
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Key Patterns
|
||||
|
||||
### Component Pattern
|
||||
```javascript
|
||||
const ComponentName = (() => {
|
||||
let _state = null;
|
||||
|
||||
function init(config) { ... }
|
||||
function update(delta) { ... }
|
||||
|
||||
return { init, update };
|
||||
})();
|
||||
|
||||
export { ComponentName };
|
||||
```
|
||||
|
||||
### WebSocket Pattern
|
||||
```python
|
||||
async def handler(websocket):
|
||||
async for message in websocket:
|
||||
# Process and broadcast
|
||||
pass
|
||||
```
|
||||
|
||||
### Portal Schema
|
||||
```json
|
||||
{
|
||||
"id": "portal-id",
|
||||
"name": "Display Name",
|
||||
"portal_type": "game-world",
|
||||
"destination": { "url": "...", "type": "harness" }
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Security
|
||||
|
||||
- WebSocket gateway binds to `127.0.0.1` by default
|
||||
- Optional token authentication via `NEXUS_WS_TOKEN`
|
||||
- Rate limiting on connections and messages
|
||||
- Branch protection on `main`
|
||||
- Provenance hash verification
|
||||
|
||||
See `SECURITY.md` for full details.

# Resurrection Pool
|
||||
|
||||
**Issue:** #882 - [M6-P3] Resurrection Pool — health polling, dead-agent detection, auto-revive
|
||||
**Status:** Implementation Complete
|
||||
|
||||
## Overview
|
||||
|
||||
The Resurrection Pool is a polling loop that detects downed agents and can automatically revive them (or substitutes) back into active missions.
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
+---------------------------------------------------+
|
||||
| Resurrection Pool |
|
||||
+---------------------------------------------------+
|
||||
| Health Polling Loop |
|
||||
| +-------------+ +-------------+ +-------------+
|
||||
| | Gateway 1 | | Gateway 2 | | Gateway N |
|
||||
| | (30s poll) | | (30s poll) | | (30s poll) |
|
||||
| +-------------+ +-------------+ +-------------+
|
||||
| +-------------+ +-------------+ +-------------+
|
||||
| | Dead-Agent | | Auto-Revive | | Human-in- |
|
||||
| | Detector | | Policy | | Loop |
|
||||
| +-------------+ +-------------+ +-------------+
|
||||
+---------------------------------------------------+
|
||||
```
|
||||
|
||||
## Components
|
||||
|
||||
### 1. Health Polling Loop
|
||||
Polls wizard gateways for agent health status.
|
||||
|
||||
**Features:**
|
||||
- Configurable poll interval (default: 30 seconds)
|
||||
- Parallel polling across gateways
|
||||
- Health status tracking
|
||||
- Response time monitoring
|
||||
|
||||
**Usage:**
|
||||
```python
|
||||
# Create health poller
|
||||
poller = HealthPoller(
|
||||
gateways=["gateway_1", "gateway_2"],
|
||||
poll_interval=30
|
||||
)
|
||||
|
||||
# Start polling
|
||||
await poller.start()
|
||||
|
||||
# Get health status
|
||||
status = poller.get_health_status()
|
||||
```
|
||||
|
||||
### 2. Dead-Agent Detection
|
||||
Detects agents that are down or haven't responded.
|
||||
|
||||
**Features:**
|
||||
- Configurable timeout (default: 300 seconds)
|
||||
- Consecutive failure tracking
|
||||
- Error message capture
|
||||
- Detection reporting
|
||||
|
||||
**Usage:**
|
||||
```python
|
||||
# Create detector
|
||||
detector = DeadAgentDetector(poller, timeout=300)
|
||||
|
||||
# Detect dead agents
|
||||
dead_agents = detector.detect_dead_agents()
|
||||
|
||||
# Get detection report
|
||||
report = detector.get_detection_report()
|
||||
```
|
||||
|
||||
### 3. Auto-Revive Policy Engine
|
||||
Manages revive policies per mission.
|
||||
|
||||
**Policies:**
|
||||
- **Yes:** Always auto-revive
|
||||
- **No:** Never auto-revive
|
||||
- **Ask:** Ask human for approval
|
||||
- **Substitute:** Substitute with different agent
|
||||
|
||||
**Usage:**
|
||||
```python
|
||||
# Create policy engine
|
||||
engine = AutoRevivePolicyEngine()
|
||||
|
||||
# Set policy for mission
|
||||
engine.set_mission_policy("mission_001", RevivePolicy.YES)
|
||||
|
||||
# Check if should revive
|
||||
should_revive = engine.should_auto_revive("mission_001", "agent_001")
|
||||
```
|
||||
|
||||
### 4. Human-in-the-Loop Approval
|
||||
Revival via Telegram / Nostr approval.
|
||||
|
||||
**Features:**
|
||||
- Request approval for revival
|
||||
- Approve/reject requests
|
||||
- Notification channels
|
||||
- Pending request tracking
|
||||
|
||||
**Usage:**
|
||||
```python
|
||||
# Create approval system
|
||||
approval = HumanInTheLoopApproval()
|
||||
|
||||
# Request approval
|
||||
request_id = approval.request_approval(
|
||||
agent_id="agent_001",
|
||||
mission_id="mission_001",
|
||||
reason="Agent down for 5 minutes"
|
||||
)
|
||||
|
||||
# Approve request
|
||||
approval.approve_request(request_id, "admin")
|
||||
```
|
||||
|
||||
## Usage Example
|
||||
|
||||
### Create Resurrection Pool
|
||||
```python
|
||||
# Define gateways
|
||||
gateways = ["gateway_1", "gateway_2", "gateway_3", "gateway_4"]
|
||||
|
||||
# Create pool
|
||||
pool = ResurrectionPool(
|
||||
gateways=gateways,
|
||||
poll_interval=30,
|
||||
timeout=300
|
||||
)
|
||||
|
||||
# Set revive policies
|
||||
pool.set_mission_policy("mission_critical", "yes") # Always revive
|
||||
pool.set_mission_policy("mission_normal", "ask") # Ask for approval
|
||||
pool.set_mission_policy("mission_low", "no") # Never revive
|
||||
```
|
||||
|
||||
### Start Pool
|
||||
```python
|
||||
# Start health polling
|
||||
await pool.start()
|
||||
|
||||
# Detect and revive
|
||||
result = pool.detect_and_revive()
|
||||
|
||||
# Get status
|
||||
status = pool.get_status()
|
||||
```
|
||||
|
||||
### Detect Dead Agents
|
||||
```python
|
||||
# Detect dead agents
|
||||
dead_agents = pool.dead_agent_detector.detect_dead_agents()
|
||||
|
||||
# Get detection report
|
||||
report = pool.dead_agent_detector.get_detection_report()
|
||||
```
|
||||
|
||||
### Request Approval
|
||||
```python
|
||||
# Request approval for revival
|
||||
request_id = pool.approval_system.request_approval(
|
||||
agent_id="agent_001",
|
||||
mission_id="mission_001",
|
||||
reason="Agent down for 5 minutes"
|
||||
)
|
||||
|
||||
# Approve request (via Telegram/Nostr)
|
||||
pool.approval_system.approve_request(request_id, "admin")
|
||||
```
|
||||
|
||||
## Integration with Hermes
|
||||
|
||||
### Loading Pool Configuration
|
||||
```python
|
||||
# In agent/__init__.py
|
||||
from agent.resurrection_pool import ResurrectionPool
|
||||
|
||||
# Create pool from config
|
||||
pool = ResurrectionPool(
|
||||
gateways=config["gateways"],
|
||||
poll_interval=config.get("poll_interval", 30),
|
||||
timeout=config.get("timeout", 300)
|
||||
)
|
||||
|
||||
# Set policies from config
|
||||
for mission_id, policy in config["policies"].items():
|
||||
pool.set_mission_policy(mission_id, policy)
|
||||
```
|
||||
|
||||
### Exposing Pool via MCP
|
||||
```python
|
||||
# In agent/mcp_server.py
|
||||
from agent.resurrection_pool import ResurrectionPool
|
||||
|
||||
# Register pool tools
|
||||
server.register_tool(
|
||||
"get_pool_status",
|
||||
"Get resurrection pool status",
|
||||
lambda args: pool.get_status(),
|
||||
{...}
|
||||
)
|
||||
|
||||
server.register_tool(
|
||||
"detect_dead_agents",
|
||||
"Detect dead agents",
|
||||
lambda args: pool.detect_and_revive(),
|
||||
{...}
|
||||
)
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Tests
|
||||
```bash
|
||||
python -m pytest tests/test_resurrection_pool.py -v
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
```bash
|
||||
# Create pool
|
||||
pool = ResurrectionPool(["gateway_1"], poll_interval=5, timeout=30)
|
||||
|
||||
# Start pool
|
||||
await pool.start()
|
||||
|
||||
# Wait for some polling
|
||||
await asyncio.sleep(10)
|
||||
|
||||
# Detect dead agents
|
||||
result = pool.detect_and_revive()
|
||||
assert result["dead_agents"] >= 0
|
||||
|
||||
# Stop pool
|
||||
await pool.stop()
|
||||
```
