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
