# State Fork — Guardrails and Fix Pattern

When the same `task_id` is held in multiple tabs, agents, or sessions, their memories may diverge.  
This creates **two or more competing state branches**, producing unstable or contradictory answers.

---

## Symptoms
- Two browser tabs answer the same task differently.  
- Multi-agent orchestration produces **conflicting citations**.  
- Session resumes but history appears **rewritten or selectively dropped**.  
- Answers alternate between two incompatible interpretations.  
- Logs show inconsistent `mem_rev` or `mem_hash` values for the same `task_id`.

---

## Root causes
- Concurrent writes to the same memory namespace.  
- Missing checks for `mem_rev` version control.  
- Agents refreshing at different times and overwriting buffers.  
- Weak schema: task identity not fenced by `{task_id, mem_rev, mem_hash}`.  
- No conflict resolution logic when branches emerge.

---

## Fix in 60 seconds
1. **Version control memory**
   - Every write stamped with `{task_id, mem_rev, mem_hash}`.  
   - Reject writes if `mem_rev` < server `mem_rev`.  
   - Require conflict resolution if two branches exist.

2. **Isolate namespaces**
   - Each agent/tab gets unique memory slot.  
   - If collaboration required, merge through a **coordinator agent**.  

3. **Detect divergence early**
   - Measure ΔS(answerA, answerB) across tabs.  
   - If ΔS ≤ 0.40 but snippets differ, state fork detected.  

4. **Resolve fork**
   - Run reconciliation: pick majority snippet set, or force human confirm.  
   - Hash merged state and issue new `{mem_rev, mem_hash}`.  

5. **Trace schema**
   - Require all claims to cite snippet ids.  
   - Reject orphan claims without snippet anchors.

## Copy-paste diagnostic prompt
```txt
You have TXTOS and the WFGY Problem Map.

Task: Detect and repair state forks across tabs or agents.

Protocol:
1. Print {task_id, mem_rev, mem_hash}.
2. If two active branches share task_id with different mem_rev → flag fork.
3. Compare ΔS(answerA, answerB).
   - If ΔS ≤ 0.40 but snippets differ → fork confirmed.
4. Apply resolution:
   - Choose majority snippet set or request human input.
   - Issue new {mem_rev, mem_hash}.
5. Report ΔS, λ states, and resolution path.
````

---

## Acceptance targets

* No conflicting branches for the same `task_id`.
* All writes validated against server-side `mem_rev`.
* ΔS(answerA, answerB) ≥ 0.60 after resolution.
* λ remains convergent across three paraphrases.
* Audit log records merge or reject actions explicitly.
