Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

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 Use this page when retrieved data may be out of date, unmaintained, or legally required to expire.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RAG retrieves documents that are outdated but still present in the index.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Outdated answers from old policies	No expiry metadata on ingestion	data-contracts.md
Deprecated snippets retrieved	Index not refreshed after content change	retrieval-playbook.md
Conflicting answers (old vs new)	Stale embeddings and no version hashing	context-drift.md
Expired docs still cited	Traceability schema missing `expiry_date`	retrieval-traceability.md

Fix in 60 seconds

Add expiry metadata on ingestion:

{
  "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.
