# 🤝 Agent Consensus Protocols  
*Make two (or ten) LLMs reach a decision **on time** and **on budget** — every run.*

> **Why this page?**  
> “Let them debate” sounds cool until:  
> * the Critic never stops nit-picking,  
> * the Planner forgets half the context,  
> * the Coder ships five conflicting drafts, and  
> * your bill looks like a crypto rug-pull.  
>   
> WFGY adds measurable **semantic tension (ΔS)** and **logic vectors (λ)** to debate & QA loops, so you can **prove** consensus is reached — not guessed.

## 1 · Three Canonical Consensus Modes

| Mode | Use Case | # Agents | Target ΔS | Target λ |
|------|----------|---------:|----------:|----------|
| **Critic-Coder** | Code/SQL generation with review | 2 | ≤ 0.40 | convergent |
| **Triad Debate** | Fact-check or legal reasoning | 3 | ≤ 0.45 | convergent |
| **Crew Vote** | 4 – 10 micro-agents on long plan | N | ≤ 0.50 | majority convergent |

*ΔS ceiling rises gently with group size; λ must return to convergent after each round.*

---

## 2 · Failure Modes (Why Votes Stall)

| # | Failure | ΔS / λ Symptom | Example |
|--:|---------|----------------|---------|
| 1 | **Infinite Debate** | λ oscillates (→, ←, →…) | Critic re-opens same defect |
| 2 | **Topic Drift** | ΔS > 0.60 vs. original prompt | Agents add new, unrelated goals |
| 3 | **Split Brain** | Two stable but divergent λ | 50 / 50 vote, no tie-breaker |
| 4 | **Early Merge** | ΔS still 0.55 but λ forced convergent | “Agree to disagree” w/ wrong answer |
| 5 | **Token Exhaust** | E_resonance ↑ while ΔS unchanged | Loop burns context without progress |

---

## 3 · WFGY Consensus Blueprint

> Four guard layers; plug into any framework (AutoGen, LangChain, custom asyncio).

| Layer | Module | Guard | Effect |
|-------|--------|-------|--------|
| **Round ΔS Checker** | BBMC | ΔS(agent, goal) ≤ ceiling | Drop off-topic vote |
| **λ Mediator** | ΔS + λ | λ must converge within 3 rounds | Force re-focus or escalate |
| **Vote Auditor** | WAI | JSON vote schema + arg defaults | No partial / malformed votes |
| **BBCR Fallback** | BBCR | > 5 rounds OR ΔS stagnates | Collapse & request human tie-break |

## 4 · Practical Setup (AutoGen example)

```python
from autogen import AssistantAgent, UserProxyAgent
from wfgy import consensus_filter

critic = AssistantAgent(name="critic")
coder  = AssistantAgent(name="coder")
user   = UserProxyAgent("user")

def callback(messages, state):
    # 1. measure ΔS + λ
    ok = consensus_filter(messages, ceiling=0.45, rounds=3)
    if not ok:
        return "STOP_DEBATE"
    return "CONTINUE"

coder.register_reply(callback)
critic.register_reply(callback)
```

*15 lines → loop stops automatically when convergence proven or impossible.*

---

## 5 · Debug Walk-Through

1. **Log votes**

```python
print(state.votes)   # {critic: "reject, ΔS=0.48", coder: "accept, ΔS=0.41"}
```

2. **Inspect λ trend**

```
λ sequence: → → ← →  (oscillating)  ❌
```

> Two divergent rounds trigger Mediator → requests narrowing question.

3. **Trigger BBCR**

```
ΔS stagnates at 0.52 for 3 rounds → BBCR => "Need human tie-break"
```

## 6 · Best-Practice Table

| Tip                                        | Why                                  |
| ------------------------------------------ | ------------------------------------ |
| **Keep each vote to max 300 tokens.**      | Reduces E\_resonance; easier ΔS calc |
| **Pin goal & constraints in every round.** | Prevents silent prompt drift         |
| **Summarise before vote.**                 | Normalises embeddings → fair ΔS      |
| **Record vote reason (1-2 lines).**        | Faster root-cause when split-brain   |
