Stabilize **long windows** and **multi-session memory**.  
This map helps you repair drift, collapse, forks, and ghost contexts when conversations or documents stretch far beyond the usual size.

---

## What this page is
- A **beginner-friendly checklist** for long contexts and multi-day sessions.
- **Copy-paste guardrails** that stop drift and collapse before they spread.
- **Concrete metrics** with ΔS and λ_observe so you know if your system is stable.

---

## When to use
- Dialog grows past **50k–100k tokens** and answers degrade.  
- Facts flip after **tab refresh** or **model switch**.  
- Citations look right but reasoning goes **flat or chaotic**.  
- OCR transcripts look fine but **capitalization or spacing drift**.  
- Multi-day support threads **lose task state** or **rewrite history**.

| [entropy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/entropy-collapse.md) | Attention melt in long windows | Outputs drift into filler |
| [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/context-drift.md) | Long reasoning drift | Correct early, wrong later |
| [pattern_memory_desync.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/pattern_memory_desync.md) | Cross-tab & cache hazards | State flips after refresh |
| [ghost-context.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/ghost-context.md) | Stale buffers & residue | Model recalls “phantom” text |
| [state-fork.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/state-fork.md) | Divergent memory forks | Same task_id, different answers |

| [chunking-checklist.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/MemoryLongContext/chunking-checklist.md) | Chunk stability at joins | Mid-sentence cuts or overlaps |

---

## Acceptance targets
- Retrieval coverage **≥ 0.70** to the intended section  
- ΔS(question, retrieved) **≤ 0.45** and joins **≤ 0.50**  
- λ_observe remains **convergent** across 3 paraphrases  
- No state fork across tabs or agents for the same `task_id`  

---

## 60-second fix checklist

1. **Lock metrics** — same analyzer & embeddings across sessions.  
2. **Enforce memory fences** — require `task_id`, `session_id`, and `snippet_id`.  
3. **Probe ΔS and λ** — run 3 paraphrases × 2 seeds.  
4. **Patch drift** — realign chunks, re-check OCR, drop ghost spans.  
5. **Audit consistency** — run traceability logs and verify continuity across restarts.
