feat: add GENOME.md — full codebase analysis

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.

+> 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.

-# Mission Cell Directory Spec
-
-This document defines the foundational Mission Cell filesystem contract for Lazarus Pit.
-It is a grounded M6 foundation slice, not the full Mission Cell runtime.
-
-Root layout:
-- `/var/missions/<uuid>/`
-
-Required subdirectories:
-- `meta/`
-- `config/`
-- `state/`
-- `logs/`
-- `artifacts/`
-- `worktree/`
-
-Required seed files:
-- `meta/mission.json`
-- `config/cell.json`
-- `state/heartbeat.json`
-- `logs/daemon.log`
-
-## Intent of each path
-
-- `meta/mission.json`
-  - durable mission identity and lifecycle metadata
-  - includes `mission_id`, `created_at`, and current status
-- `config/cell.json`
-  - local cell wiring
-  - points to the worktree, artifacts directory, and heartbeat file
-- `state/heartbeat.json`
-  - latest cell heartbeat timestamp and state
-  - consumed by Lazarus Pit scans for healthy vs stale cell classification
-- `logs/daemon.log`
-  - daemon-local operational log target
-- `artifacts/`
-  - handoff packets, reports, checkpoints, and mission outputs
-- `worktree/`
-  - mission-specific checked-out repository workspace
-
-## Lazarus Pit daemon skeleton
-
-`scripts/lazarus_pit.py` provides the foundation daemon behavior:
-- initialize a Mission Cell scaffold with `--init-cell <uuid>`
-- scan all cells under the configured missions root
-- classify cells as `healthy`, `stale`, `incomplete`, or `uninitialized`
-- emit a daemon heartbeat through the existing cron heartbeat writer
-- output a JSON health report for higher-level watchers
-
-Default config lives at:
-- `config/lazarus_pit.json`
-
-## Example bootstrap
-
-```bash
-python3 scripts/lazarus_pit.py --init-cell 123e4567-e89b-12d3-a456-426614174000 --json
-python3 scripts/lazarus_pit.py --write-heartbeat --json
-```
-
-## What remains for full #879 completion
-
-This slice does not yet complete the whole issue.
-Still open:
-- health heartbeat endpoint on existing wizard gateways
-- Gitea mission proposal issue template
-- live daemon service wiring / long-running supervisor integration
