# 📒 Deep Dive · Cross‑Agent Memory Overwrite (Placeholder)

> **Status:** WIP — awaiting real logs that show one agent erasing another’s state.

---

## 🔍 Typical Overwrite Scenario

* **Agent A** saves `Plan v1` → **Agent B** unknowingly commits `Plan v0` over it  
* Vector store returns *last‑writer‑wins* → earlier context disappears  
* Later conversation references missing data → hallucination or contradiction

## 📝 Help Us Harden the Fix

| What to Submit | Where | Why |
|----------------|-------|-----|
| JSON / text trace of overwrite | New **Discussion → Memory Overwrite Trace** | Build regression test |
| Framework info (LangChain, AutoGen …) | Same thread | Tune adapter layer |
| Desired guardrail behavior | Comment | Define acceptance criteria |

---

## 🛠 Planned Guardrail Outline

1. **Node Version Stamp** — each write carries `agent_id + timestamp + version`.  
2. **ΔS Collision Alert** — large semantic mismatch triggers “merge or fork?” prompt.  
3. **BBCR Reconcile** — automatic three‑way merge or safe branch to preserve both states.
