# Jan: Guardrails and Fix Patterns
[Jan](https://jan.ai) is a desktop-native inference environment that allows you to run local LLMs with a polished UI, cross-platform support, and tight integration with quantized model formats.
While easier to use than CLI runtimes, Jan inherits common problems: unstable context handling, schema drift, citation loss, and device-specific crashes.
This page gives WFGY-based fixes to stabilize Jan deployments.

## Common Jan breakpoints
| Symptom | Likely Cause | Fix |
| ------------------------------------- | --------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| First run fails on GPU device | CUDA/Metal init order | [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) |
| Correct snippets but drifting answers | Schema mismatch in local context buffer | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |
| Answers alternate between runs | λ flip, unstable headers | [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md) |
| JSON parse breaks | Inconsistent serialization in UI layer | [logic-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md) |
| Safety refusal hides citations | Missing citation-first prompting | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) |

## Fix in 60 seconds
1. **Run warm-up**: issue a small dummy query to stabilize device kernels.
2. **Schema enforce**: lock JSON outputs for tools and citations.
3. **Trace citations**: enforce cite-then-explain.
4. **Measure ΔS and λ**: if ΔS ≥ 0.60, rebuild index with proper embedding metric.
5. **Watch entropy**: reset conversation memory after 4k8k tokens or entropy rise.

## Diagnostic prompt (copy-paste)
```txt
I am using Jan to run a local GGUF/GGML model.
Question: "{user_question}"
Return:
- ΔS(question, retrieved)
- λ across paraphrases and seeds
- JSON schema compliance
- Which WFGY fix page to open if ΔS ≥ 0.60
```
