[](https://dev.tourl/)Governance‑First! Before Retrieval? Most RAG pipelines are still built the old way: retrieve broadly → filter → hope nothing leaks

That pattern is convenient, but in multi‑tenant or regulated workloads it’s structurally unsafe. Once the model has already seen unauthorised embeddings, you’ve lost the guarantee.

TenantSage flips the pattern: , tenant scope, and legal‑hold rules are applied before retrieval, so restricted content never reaches the ranking step — and never touches the model.

Why Post‑Filtering Fails in Multi‑Tenant RAG

When filtering only happens after semantic retrieval, several predictable risks emerge:

• Permission drift

Embedding chunks don’t automatically update when source permissions change.

• Cross‑tenant leakage

Similarity search doesn’t respect tenant boundaries unless enforced upfront.

• Legal‑hold exposure

Restricted documents can still enter the candida
