Tenant-Isolated Retrieval for Healthcare Appointment Assistants — A Traceable Runbook

Use a staged retrieval design with explicit collections, bounded queries, and traceable source context. For a healthcare appointment assistant, tenant isolation is part of the answer contract, not a setting to bolt on after relevance tuning. Short answer: give every tenant an explicit collection boundary, query only that boundary with hard limits and timeouts, and return document identifiers or…

The article discusses the importance of a traceable runbook for tenant-isolated retrieval in healthcare appointment assistants. The key points are:

1. Implement a staged retrieval design with explicit collections, bounded queries, and traceable source context.

2. Assign each tenant an explicit collection boundary to ensure isolation.

3. Query only the assigned collection with hard limits and timeouts, returning document identifiers or source URLs alongside each passage.

4. Treat ingestion, deletion, and re-indexing as deliberate operations with an audit trail.

5. A relevant answer from the wrong clinic can easily go unnoticed in a demo, resulting in incorrect information being provided.

6. The failure mode should be treated as a retrieval incident, not a prompt incident.

7. Create a concise answer contract that includes tenant scope, bounded passages, source URLs or document identifiers, and a refusal or escalation path when no in-scope source exists.

8. Shape the retrieval architecture for each tenant before generating embeddings.

9. Use a naming rule that includes an immutable tenant identifier for collection names, but never accept arbitrary collection names from users.

10. Perform tenant authorization during mapping from the authenticated application tenant to the collection.

11. Implement a staged flow: resolve tenant's allowed collection, issue a bounded vector query, and validate returned records carry the expected tenant and source reference before passing context to the language model.

12. If any check fails, stop the answer path and log the request ID.

13. Provide a sample Go client code demonstrating the trust boundary, explicit route and method, API key from the environment, and timeout to prevent slow retrieval from holding up the appointment flow.

14. Choose a retrieval boundary that prevents cross-tenant reads and allows proof of isolation.

15. Consider using Pinecone, Weaviate, or pgVector based on operational trade-offs and fit for the healthcare appointment assistant.

Shared Agent Memory Leaks. Enforce the Boundary in PostgreSQL

Agents with long-term memory often keep it in one vector store shared by many users, and often by many agents. Ownership is a metadata column, and the boundary is a WHERE clause in application code.

  • Shared memory among agents can cause up to 70-100% data leakage without external attackers.
  • Four frameworks tested lacked ability to intercept inter-agent messages.

Legal Contract Review Retrieval: Tenant Isolation Through Bounded, Traceable Context

Short answer: use a staged retrieval design in which every legal document belongs to an explicit collection, every query is bounded to the intended tenant and access scope, and every returned passage…

  • Treat legal contract review retrieval as a contract, not a similarity-search demo
  • Use explicit collections as boundaries for tenant isolation
  • Reject any result that crosses tenant boundaries during retrieval
