+# Ghost Context — Guardrails and Fix Pattern
+
+When personas, roles, or long sessions change, old buffers may linger.  
+These stale fragments contaminate new answers, creating phantom references or role bleed.
+
+---
+
+## Symptoms
+- Answer contains facts or tone from a **previous persona** even after reset.  
+- Citations look valid but reference sections from a **past session**.  
+- A new task starts yet responses **drift back to old task context**.  
+- Model insists on constraints that were valid in an earlier role but not now.  
+- Answers feel “haunted” by old memory traces.
+
+---
+
+## Root causes
+- Hidden buffers not cleared after system or role switch.  
+- State variables (persona, role, policy) not reset between sessions.  
+- Token reuse from stale cache layers.  
+- ΔS stays abnormally low even when task has switched domains.  
+- λ\_observe shows convergence to an **irrelevant anchor**.
+
+---
+
+## Fix in 60 seconds
+1. **Stamp and reset state**  
+   Require `{mem_rev, mem_hash, persona_id}` on each turn.  
+   If persona_id differs from previous → force buffer clear.
+
+2. **Fence the prompt schema**  
+   Assemble prompts as `{system | persona | constraints | snippets | answer}`.  
+   Do not let persona or role tokens bleed into snippet blocks.
+
+3. **Drop stale buffers**  
+   When persona changes, zero all prior hidden states.  
+   Require fresh snippets for new context.
+
+4. **Probe for contamination**  
+   - Compute ΔS(new question, retrieved snippet).  
+   - If ΔS ≤ 0.30 but snippets belong to past persona → ghost detected.  
+   - Trigger hard reset and request new anchors.
+
+5. **Audit the joins**  
+   Compare ΔS across old vs new persona snippets.  
+   Require ΔS(new persona, old snippet) ≥ 0.65 before allowing reuse.
+
+---
+
+## Copy-paste diagnostic prompt
+```txt
+You have TXTOS and the WFGY Problem Map.
+
+Task: Detect and purge ghost context.
+
+Steps:
+1. Print {mem_rev, mem_hash, persona_id}.
+2. Verify that current persona_id matches task scope.
+3. If snippets cite a different persona_id, mark as ghost.
+4. Require re-retrieval for ghosted snippets.
+5. Report:
+   - ΔS(new question, retrieved)
+   - ΔS(new persona vs old snippets)
+   - λ states
+   - Reset actions taken
+````
+
+---
+
+## Acceptance targets
+
+* ΔS(new question, retrieved) ≤ 0.45
+* Coverage ≥ 0.70 to the new target section
+* λ remains convergent across three paraphrases
+* No snippet contamination from old persona or task scope
