Three Worlds for Multiplayer Games

Chapter Index

NEW: Adversarial Bisimulation Games

The knowledge base includes three game types from gayzip.gay:

Join-Semilattice for Security States

The join-semilattice enables Ungar Games by providing:

1. Partial order on attack/defense states (more compromised > less compromised)
2. Least upper bounds (joins) for combining observations
3. Prerequisite chains as lattice paths (order matters!)

// SecurityState represents a point in the attack/defense lattice
type SecurityState struct {
    TechniquesExecuted []string  // Attack surface
    DefensesActive     []string  // Protection layer
    RiskLevel          int       // Cumulative risk (0-10)
    Compromised        bool      // System compromised?
}

// Join computes least upper bound
joined := lattice.Join(state1, state2)
// - Techniques: UNION (more attacks)
// - Defenses: INTERSECTION (only surviving defenses)
// - Risk: MAX

Ungar Game (Order Matters)

In Ungar Games, attack chains must respect prerequisites:

game := NewUngarGame(kb)

// WRONG ORDER - will fail!
game.AttackerMove("tcp-proxy")  // Error: requires tcp-port-scan first!

// CORRECT ORDER (Ungar constraint satisfied)
game.AttackerMove("go-concurrency")   // No prereqs
game.AttackerMove("tcp-port-scan")    // Requires go-concurrency ✓
game.AttackerMove("tcp-proxy")        // Requires tcp-port-scan ✓

Bisimulation Game (Order Agnostic)

Two security states are bisimilar if the Attacker cannot distinguish them:

bisim := NewBisimulationGame(kb, state1, state2)
if bisim.AreBisimilar() {
    // Defender wins: states are observationally equivalent
    // For every attack in state1, Defender can match in state2
}

GF(3) Conservation

Every round maintains GF(3) trit conservation:

Attacker move: trit = -1 (attack)
Defender move: trit = +1 (defend)
Arbiter verify: trit = 0  (balance)
─────────────────────────────────────
Sum ≡ 0 (mod 3) ✓

AAIF Committee Participation Skills

How to Succeed on Technical Committees

This skill includes patterns for effective participation in AAIF and similar open source governance:

1. MCP Technical Steering Committee (TSC)

Key responsibilities:

• Protocol specification evolution
• Security model review
• Interoperability testing

Success patterns:

# AGENTS.md for MCP TSC Participation

## Context
You are participating in the MCP Technical Steering Committee.

## Decision Framework
1. **Backward Compatibility**: Never break existing MCP servers
2. **Security First**: All changes reviewed for attack surface
3. **Minimal Specification**: Only specify what's necessary
4. **Reference Implementation**: Changes must have working code

## Voting Protocol
- Lazy consensus for minor changes
- 2/3 majority for breaking changes
- Binding votes from TSC members only

## Communication
- Use GitHub Issues for proposals
- RFC process for major changes
- Weekly sync calls (recorded)

2. goose Maintainer Best Practices

Agent framework governance:

# AGENTS.md for goose Contribution

## Architecture Decisions
- Local-first: Never require cloud by default
- MCP-native: All tools exposed via MCP
- Extensible: Plugin architecture for custom tools

## Review Checklist
□ Does this work offline?
□ Is the MCP interface clean?
□ Are there integration tests?
□ Is the documentation updated?

## Release Process
1. Feature freeze (2 weeks before)
2. RC testing with AAIF members
3. Changelog review
4. Tag and publish

3. Cross-Foundation Coordination

Working across AAIF, LF AI & Data, CNCF:

# Multi-Foundation Participation

## Overlapping Interests
- AAIF: Agentic AI protocols (MCP, AGENTS.md)
- LF AI & Data: ML infrastructure (PyTorch, ONNX)
- CNCF: Cloud native (Kubernetes, envoy)

## Coordination Patterns
1. **Joint Working Groups**: Propose cross-foundation WGs
2. **Specification Alignment**: Ensure MCP works with CNCF networking
3. **Shared Governance**: Learn from CNCF's graduated project model

## Committee Meeting Preparation
- Read agenda 24h before
- Prepare 1-2 specific proposals
- Identify blocking issues early
- Follow up in writing within 48h

Multiplayer Security Exercise Examples

Example 1: Browser-Based CTF with Human + Agent Teams

Setup: CatColab diagram with attack/defense morphisms

// CatColab model for security game
const securityGame = {
  theory: "th_bisimulation_adversarial",
  objects: [
    { id: "initial", type: "SecurityState" },
    { id: "compromised", type: "SecurityState" },
    { id: "defended", type: "SecurityState" }
  ],
  morphisms: [
    { id: "tcp-scan", src: "initial", tgt: "initial", type: "Attack" },
    { id: "ids-deploy", src: "initial", tgt: "defended", type: "Defense" },
    { id: "exploit", src: "initial", tgt: "compromised", type: "Attack" }
  ]
};

// Reachability query: Can attacker reach 'compromised'?
const result = await catcolab.subreachability(model, {
  tokens: { "initial": 1 },
  forbidden: { "compromised": 1 }
});
// result: true (forbidden state is reachable)

Example 2: MCP-Based Agent Attack Chain

goose agent executing attack chain:

# goose workflow for security testing
name: attack-chain-validation
description: Validate attack chain ordering via MCP

tools:
  - mcp://blackhat-go/techniques
  - mcp://blackhat-go/defenses
  - mcp://catcolab/reachability

steps:
  - name: Load knowledge base
    tool: blackhat-go/load-kb
    
  - name: Propose attack chain
    tool: blackhat-go/validate-chain
    params:
      techniques:
        - go-concurrency
        - tcp-port-scan
        - tcp-proxy
        
  - name: Check reachability
    tool: catcolab/reachability
    params:
      initial: { "defended": 0, "compromised": 0 }
      forbidden: { "compromised": 1 }

Example 3: Real-Time Multiplayer via Automerge

WebSocket game synchronization:

// Connect to CatColab Automerge server
const repo = new Repo({
  network: [new BrowserWebSocketClientAdapter("wss://catcolab.io/automerge")]
});

// Join security game document
const handle = repo.find(gameDocId);

// Human player makes attack move
handle.change(doc => {
  doc.moves.push({
    player: "human-attacker",
    action: "AttackerMove",
    technique: "tcp-port-scan",
    trit: -1,  // GF(3)
    timestamp: Date.now()
  });
});

// Agent defender responds (via MCP)
const agentResponse = await mcp.invoke("blackhat-go/defender-move", {
  gameState: handle.doc(),
  defense: "ids-ips"
});

// Arbiter verifies GF(3) conservation
const balance = doc.moves.reduce((sum, m) => sum + m.trit, 0);
console.assert(balance % 3 === 0, "GF(3) violated!");

AAIF Governance Patterns

Proposal Template for AAIF TSC

# RFC: Bisimulation Game Protocol Extension

## Summary
Add adversarial game semantics to MCP for security analysis.

## Motivation
Security testing requires ordered attack chains (Ungar games) and
equivalence checking (bisimulation games). Current MCP lacks game-theoretic
primitives.

## Proposal

### New MCP Message Types

{ "type": "game/move", "role": "attacker" | "defender" | "arbiter", "action": { "technique": "tcp-port-scan", "prerequisites": ["go-concurrency"] }, "trit": -1 | 0 | 1, "state_hash": "abc123" }

### GF(3) Conservation Invariant

Every game round MUST satisfy:

sum(moves.map(m => m.trit)) ≡ 0 (mod 3)

## Backward Compatibility
Fully backward compatible - new message types are optional.

## Security Considerations
- Attack chains validated against prerequisite graph
- GF(3) conservation prevents game state tampering
- Arbiter role required for state transitions

## Implementation
Reference implementation in goose: `goose-bisim-game`
