Keep multi-turn and multi-session dialogs stable by fencing memory state.
This page shows how to prevent forks, desync, and ghost buffers when conversations span long contexts or multiple agents.
---
## When to use this page
- Long support chats (~days) forget earlier task context.
- Model switches or tab refreshes flip prior facts.
- Two agents on the same ticket give inconsistent answers.
- OCR transcripts look fine but later steps rewrite history.
- Persona or role change contaminates state with old context.
---
## Core acceptance targets
- Each turn stamped with `mem_rev` and `mem_hash`.
- No forks across sessions for the same `task_id`.
- ΔS(question, retrieved) ≤ 0.45 with joins ≤ 0.50.
- λ remains convergent across three paraphrases.
- All claims cite snippet_id, no orphans.
---
## Structural fixes
- **Stamp and fence**
Require `mem_rev`, `mem_hash`, and `task_id` at every turn.
Forbid writes if stamps mismatch.
- **Shard state**
Partition prompts as `{system | task | constraints | snippets | answer}`.
Forbid snippet reuse across sections.
- **Normalize consistently**
Enforce Unicode NFC, strip zero width marks, unify full/half width.
Block OCR lines below confidence threshold.
- **Recover forks**
If two agents diverge, reconcile by ΔS triangulation and pick the lower-entropy path.
- **Bridge collapse**
Apply BBCR if attention melt or desync detected mid-chain.
---
## Fix in 60 seconds
1. At turn start, echo {mem_rev, mem_hash, task_id}.
2. If stamps mismatch, reject write and request sync.
3. Split snippets by section, forbid cross-reuse.
4. Normalize all inputs.
5. Apply BBAM/BBCR if λ drifts or collapse appears.
6. Verify ΔS(question, retrieved) ≤ 0.45 and joins ≤ 0.50.

## Copy-paste prompt
```
You have TXT OS and the WFGY Problem Map.
Goal: Keep memory coherent across multi-session dialogs.
Protocol:
1. Print {mem\_rev, mem\_hash, task\_id}.
2. Assemble prompt as {system | task | constraints | snippets | answer}.
3. Enforce guardrails:
* cite then answer
* forbid cross-section reuse
* reject orphan claims without snippet\_id
4. If λ flips, apply BBAM. If collapse, insert BBCR bridge.
5. Report ΔS(question, retrieved), ΔS across joins, λ states, and final answer.
```
---
## Common failure patterns
- **State fork**: two parallel tabs rewrite history differently.
- **Ghost buffer**: old role text leaks into new session.
- **Desync**: memory IDs mismatch after refresh.
- **OCR drift**: spacing or casing breaks snippet alignment.
