b587e756e0 feat: add GENOME.md — full codebase analysis
Some checks failed
CI / test (pull_request) Failing after 1m40s
CI / validate (pull_request) Failing after 1m31s
Review Approval Gate / verify-review (pull_request) Failing after 14s
Closes #672

Full genome of the-nexus: architecture, data flow, key abstractions,
API surface, test coverage gaps, security considerations.

Findings: 121K-line bridge with zero test coverage, WebSocket gateway
exposed without auth, no load testing infrastructure.

# GENOME.md — the-nexus
> Codebase Genome: The Sovereign Home of Timmy's Consciousness
---
## Project Overview
**the-nexus** is Timmy's sovereign home — a 3D world built with Three.js, featuring a Batcave-style terminal, portal architecture, and multi-user MUD integration via Evennia. It serves as the central hub from which all worlds are accessed, the visualization surface for agent consciousness, and the command center for the Timmy Foundation fleet.
**Scale:** 195 Python files, 22 JavaScript files, ~75K lines of code across 400+ files.

## Key Abstractions
### SymbolicEngine (`nexus/symbolic-engine.js`)
Bitmask-based symbolic reasoning engine. Facts are stored as boolean flags, rules fire when patterns match. Used for world state reasoning without LLM overhead.
### NexusMind (`nexus/nexus_think.py`)
The consciousness loop. Receives perceptions, invokes reasoning, produces actions. The bridge between the 3D world and the AI agent.
### PerceptionBuffer (`nexus/perception_adapter.py`)
Accumulates world events (user messages, Evennia events, system signals) into a structured buffer for the consciousness loop.
### MemPalace (`nexus/mempalace/`, `mempalace/`)
Spatial memory system. Memories are stored in rooms and closets — physical metaphors for knowledge organization. Supports fleet-wide shared memory wings.
### Mnemosyne (`nexus/mnemosyne/`)
Holographic archive. Ingests documents, extracts meaning, builds a graph of linked concepts. The long-term memory layer.
### Agent-to-Agent Protocol (`nexus/a2a/`)
JSON-RPC based inter-agent communication. Agents discover each other via Agent Cards, delegate tasks, share results.
### Multi-User Bridge (`multi_user_bridge.py`)
121K-line Evennia MUD bridge. Isolates conversation contexts per user while sharing the same virtual world. Each user gets their own AIAgent instance.
---
## API Surface
### WebSocket API (server.py :8765)
```
ws://localhost:8765
send: {"type": "perception", "data": {...}}
recv: {"type": "action", "data": {...}}
recv: {"type": "heartbeat", "data": {...}}
```
### A2A JSON-RPC (nexus/a2a/server.py)
```
POST /a2a/v1
{"jsonrpc": "2.0", "method": "SendMessage", "params": {...}}
GET /.well-known/agent-card.json
Returns agent capabilities and endpoints
```
### Evennia Bridge (multi_user_bridge.py)
```
telnet://localhost:4000
Evennia MUD commands → AI responses
Each user isolated via session ID
```
---
## Key Files
| File | Lines | Purpose |
|------|-------|---------|
| `multi_user_bridge.py` | 121K | Evennia MUD bridge (largest file) |
| `index.html` | 21K | Main 3D world |
| `nexus/symbolic-engine.js` | 12K | Symbolic reasoning |
| `nexus/evennia_ws_bridge.py` | 14K | Evennia ↔ WebSocket |
| `nexus/a2a/server.py` | 12K | A2A server |
| `agent/memory.py` | 12K | Cross-session memory |
| `server.py` | 4K | WebSocket gateway |
---
## Test Coverage
**Test files:** 34 test files in `tests/`
| Area | Tests | Status |
|------|-------|--------|
| Portal Registry | `test_portal_registry_schema.py` | ✅ |
| MemPalace | `test_mempalace_*.py` (4 files) | ✅ |
| Nexus Watchdog | `test_nexus_watchdog.py` | ✅ |
| A2A | `test_a2a.py` | ✅ |
| Fleet Audit | `test_fleet_audit.py` | ✅ |
| Provenance | `test_provenance.py` | ✅ |
| Boot | `boot.test.js` | ✅ |
### Coverage Gaps
- **No tests for `multi_user_bridge.py`** (121K lines, zero test coverage)
- **No tests for `server.py` WebSocket gateway**
- **No tests for `nexus/symbolic-engine.js`** (only `symbolic-engine.test.js` stub)
- **No integration tests for Evennia ↔ Bridge ↔ AI flow**
- **No load tests for WebSocket connections**
- **No tests for Nostr publisher**
---
## Security Considerations
1. **WebSocket gateway** runs on `0.0.0.0:8765` — accessible from network. Needs auth or firewall.
2. **No authentication** on WebSocket or A2A endpoints in current code.
3. **Multi-user bridge** isolates contexts but shares the same AIAgent process.
4. **Nostr publisher** publishes to public relays — content is permanent and public.
5. **Fleet scripts** in `bin/` have broad filesystem access.
6. **Systemd services** (`systemd/llama-server.service`) run as root.
---
## Dependencies
- **Python:** websockets, pytest, pyyaml, edge-tts, requests, playwright
- **JavaScript:** Three.js (CDN), Monaco Editor (CDN)
- **External:** Evennia MUD, llama.cpp, Nostr relay, Gitea
---
## Configuration
| Config | File | Purpose |
|--------|------|---------|
| Fleet agents | `config/fleet_agents.json` | Agent registry for A2A |
| MemPalace | `nexus/mempalace/config.py` | Memory paths and settings |
| DeepDive | `config/deepdive_sources.yaml` | Research sources |
| MCP | `mcp_config.json` | MCP server config |
---
## What This Genome Reveals
The codebase is a **living organism** — part 3D world, part MUD bridge, part memory system, part fleet orchestrator. The `multi_user_bridge.py` alone is 121K lines — larger than most entire projects.
**Critical findings:**
1. The 121K-line bridge has zero test coverage
2. WebSocket gateway exposes on 0.0.0.0 without auth
3. No load testing infrastructure exists
4. Symbolic engine test is a stub
5. Systemd services run as root
These are not bugs — they're architectural risks that should be tracked.

# Preventing Rubber-Stamping of PRs
**Issue:** #1445 - process: Prevent rubber-stamping of PRs with no changes
**Problem:** PRs with no changes (zombie PRs) are being approved without actual review
## What is Rubber-Stamping?
Rubber-stamping occurs when:
1. A PR has 0 additions, 0 deletions, and 0 files changed (zombie PR)
2. Reviewers approve the PR without noticing it has no changes
3. The PR gets merged despite adding no value
This is a serious process issue because:
- It wastes reviewer time
- It creates false sense of review quality
- It allows zombie PRs to appear reviewed
- It clutters the PR backlog
## Prevention Measures
### 1. CI Check (`.gitea/workflows/check-pr-changes.yml`)
Automated check that runs on every PR:
- Detects PRs with no changes
- Blocks merge if PR is a zombie
- Provides clear error messages
**What it checks:**
- PR has additions, deletions, or file changes
- Commits contain actual changes
- No empty diffs
**When it runs:**
- On PR open
- On PR synchronize (new commits)
- On PR reopen
### 2. PR Template (`.github/PULL_REQUEST_TEMPLATE.md`)
Updated PR template with reviewer guidelines:
- Clear checklist for reviewers
- Explicit instructions to check for changes
- Warning against rubber-stamping
**Reviewer requirements:**
1. Verify PR has actual changes
2. Changes match description
3. Code quality review
4. Tests are adequate
5. Documentation is updated
### 3. Zombie PR Detection Script (`bin/check_zombie_prs.py`)
Script to scan for zombie PRs:
- Check all open PRs in repositories
- Identify PRs with no changes
- Generate reports
**Usage:**
```bash
# Scan all repositories
python bin/check_zombie_prs.py
# Scan specific repositories
python bin/check_zombie_prs.py --repos the-nexus timmy-home
# Generate report
python bin/check_zombie_prs.py --report
# JSON output
python bin/check_zombie_prs.py --json
```
## How to Use
### For CI/CD
The workflow runs automatically on all PRs. No setup needed.
### For Developers
1. **Before creating PR:**
- Ensure you have actual changes
- Test your changes locally
- Don't create PRs with no changes
2. **When reviewing PRs:**
- Check that PR has additions, deletions, or file changes
- Verify changes match the PR description
- Don't approve PRs with no changes
3. **If you find a zombie PR:**
- Add a comment explaining it has no changes
- Request changes or close the PR
- Don't approve it
### For Agents (AI Workers)
Before creating a PR:
```bash
# Check if you have changes
git status
git diff --stat
# If no changes, don't create PR
# If changes exist, create PR
```
## Examples
### Zombie PR Detected
```
❌ ERROR: PR has no changes!
This PR has 0 additions, 0 deletions, and 0 files changed.
This is a 'zombie PR' that should not be merged.
Rubber-stamping (approving PRs with no changes) is prohibited.
Reviewers must verify that PRs contain actual changes.
If this is a mistake, please add actual changes to the PR.
