Guardrails and fix patterns to handle the **expiry, staleness, or invalidation** of enterprise knowledge inside AI pipelines. Use this page when retrieved data may be out of date, unmaintained, or legally required to expire.
|
||
|
||
---
|
||
|
||
## When to use this page
|
||
- RAG retrieves documents that are outdated but still present in the index.
|
||
- Policies require document expiry (e.g., 3-year rotation, GDPR “right to be forgotten”).
|
||
- Model cites knowledge that has been deprecated.
|
||
- Knowledge base retains drafts or revoked versions.
|
||
|
||
---
|
||
|
||
## Core acceptance targets
|
||
- Every document has an explicit `expiry_date` or `revision_hash`.
|
||
- Retrieval never selects content beyond expiry.
|
||
- Expired or revoked documents fully deleted from vector stores.
|
||
- Audit logs record expiry enforcement at retrieval time.
|
||

## Typical expiry problems → exact fix
|
||
|
||
| Symptom | Likely cause | Open this |
|
||
|---------|--------------|-----------|
|
||
| Outdated answers from old policies | No expiry metadata on ingestion | [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |
|
||
| Deprecated snippets retrieved | Index not refreshed after content change | [retrieval-playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md) |
|
||
| Conflicting answers (old vs new) | Stale embeddings and no version hashing | [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md) |
|
||
| Expired docs still cited | Traceability schema missing `expiry_date` | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) |
|
||
|

|
||
|
||
## Fix in 60 seconds
|
||
1. **Add expiry metadata** on ingestion:
|
||
```json
|
||
{
|
||
"document_id": "policy-123",
|
||
"revision_hash": "ab89e...",
|
||
"expiry_date": "2026-01-01"
|
||
}
|
||
````
|
||
|
||
2. **Drop expired docs** from index during nightly rebuilds.
|
||
3. **Enforce live expiry check** at retrieval:
|
||
|
||
* Reject snippets where `expiry_date < today`.
|
||
* Log `expired=true` in audit record.
|
||
4. **Verify ΔS stability** only against valid revisions.

||
## Copy-paste probe template
|
||
|
||
```txt
|
||
You have TXTOS and the WFGY Problem Map loaded.
|
||
|
||
My RAG system retrieved:
|
||
- doc_id, revision_hash, expiry_date
|
||
|
||
Task:
|
||
1. Drop all snippets past expiry_date.
|
||
2. Log ΔS(question,retrieved), λ_state, and expired flag.
|
||
3. If expired=true, cite the Problem Map page to rebuild the index.
|
||
Return JSON: { "valid_snippets": [...], "expired_snippets": [...], "ΔS": 0.xx, "λ_state": "<>", "next_fix": "..." }
|
||
```
|
||
|
||
---
|
||
|
||
## Escalate when
|
||
|
||
* Same query alternates between expired and valid docs.
|
||
* Expired documents remain in retrieval despite metadata.
|
||
* Audit logs show `expiry_date` ignored during reranking.
|
||
|
||
For deeper cases, apply [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) to enforce correct load order and [ops/debug\_playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md) for runtime tracing.
