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
