Guardrails and fix patterns for enterprise knowledge retention. Use this page when AI systems over-retain, delete too early, or mix expired data with active knowledge.

|
||
|
||
## When to use this page
|
||
- AI responses reference documents that should have been deleted per policy.
|
||
- Retained snippets do not respect jurisdictional time limits (e.g., GDPR 3 years).
|
||
- Knowledge base or embeddings store does not purge revisions.
|
||
- RAG answers mix archived with active content.
|
||
|
||
---
|
||
|
||
## Core acceptance targets
|
||
- ΔS(question, expired_snippet) ≥ 0.70 → expired content must not surface.
|
||
- All snippets carry `{expiry_date, retention_scope, audit_hash}` fields.
|
||
- Coverage ≥ 0.70 within *active* retention window only.
|
||
- λ remains convergent across three paraphrases and two seeds.

## Typical retention problems → exact fix
|
||
|
||
| Symptom | Likely cause | Open this |
|
||
|---------|--------------|-----------|
|
||
| Expired docs still retrieved | Store never purged embeddings | [vectorstore-fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/vectorstore-fragmentation.md) |
|
||
| Wrong answer mixes expired + active | Snippets missing `expiry_date` field | [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |
|
||
| AI cites “archived only” docs as live | Retrieval trace missing retention scope | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) |
|
||
|
||

|
||
|
||
## Fix in 60 seconds
|
||
1. **Check ΔS to expired content**: run probe with expired snippets, expect ΔS ≥ 0.70.
|
||
2. **Schema enforcement**: require `expiry_date` and `retention_scope` in every snippet.
|
||
3. **Index purge**: remove expired embeddings before next RAG run.
|
||
4. **Audit λ**: if λ flips when expired vs active co-exist, clamp with BBAM and enforce contracts.
|

|
||
## Copy-paste schema (JSON)
|
||
|
||
```json
|
||
{
|
||
"snippet_id": "KB-5532",
|
||
"expiry_date": "2025-12-31",
|
||
"retention_scope": "eu-3y",
|
||
"audit_hash": "sha256:...",
|
||
"text": "..."
|
||
}
|
||
````
|
||
|
||
---
|
||
|
||
## Escalate when
|
||
|
||
* Expired content continues to surface after purge.
|
||
* ΔS < 0.70 against expired content → embeddings contamination.
|
||
* Audit requires full deletion trace and cannot be reproduced.
|
||
|
||
Use [retrieval-playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md) for deep purge testing and [eval\_rag\_precision\_recall.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/eval/eval_rag_precision_recall.md) to validate coverage.
