RAG: revocation must reach retrievable content
Removing source access may leave usable copies.
Content produced with AI assistance for Thiago Silva’s website. Independent editorial analysis; it does not represent clients or employers.
Reading context
A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.
Original source ↗The architecture decision
A knowledge base may retain chunks after source permissions change. Review ingestion, indexing and retrieval as one journey.
Practical application
Editorial proposal: define how deletion and access changes reach derived copies. In a hypothetical assistant, specify behavior during propagation delays.
How to verify
Using synthetic data, revoke document access and attempt retrieval through different questions. Inspect citations and cached answers too. Evidence should show what became inaccessible and when, making delays an explicit risk decision.
