+
+> 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.

-# OpenClaw Purge Report — 2026-04-12
-
-Directive: We are Hermes maxis. OpenClaw has been removed from the entire Timmy Foundation stack.
-
-## What was done
-
-### the-nexus (this repo)
- PR #1278 — Removed OpenClaw sidecar reference from README.md (merged)
- PR #1279 — Rewrote Fleet Vocabulary: deprecated Robing pattern, replaced with Hermes-native comms (merged)
- Issue #830 — Updated body to remove OpenClaw references from intelligence briefing scope
- ACTION NEEDED (rockachopa): Update org description at https://forge.alexanderwhitestone.com/Timmy_Foundation — remove `OpenClaw sidecar` from description.
-  - Current: `Sovereign AI foundation — Hermes harness, canonical Nexus repo, timmy-home training ground, OpenClaw sidecar.`
-  - New: `Sovereign AI foundation — Hermes harness, canonical Nexus repo, timmy-home training ground.`
-
-### timmy-config (complete)
- PR #487 — 7 files changed: code-claw-delegation.md, allegro-wizard-house.md, automation-inventory.md, capacity-inventory.md, topology.md, son-of-timmy.md, health_check.py (merged)
-
-### timmy-home (complete)
- PR #595 — 3 files changed: USER_AUDIT_2026-04-04.md, two greptard reports with deprecation headers (merged)
- Issue #141 closed (Robing architecture superseded)
- Issue #140 closed (lobster cutover superseded)
-
-## What was preserved
- 27 previously closed OpenClaw issues across repos — left as historical record
- Greptard memory architecture reports — preserved with deprecation headers
- The Robing/Lobster/Unrobed vocabulary entries — marked deprecated, not deleted
-
-## Remaining action
- Org description — needs org owner (rockachopa) to update. The perplexity account lacks org admin permission.
-
-## Architecture going forward
-Hermes handles everything: cognitive core, channels, dispatch, memory, cron, health monitoring. No external gateway layer. Two states: Online or Dead. No split-brain failure modes.
