Hands-on verificationComplete on demand · Suggestions15 minutes

Design handling of vector indexing, caching, and saved summaries after permission revocation.

Expand acceptance requirements and checkpoints
  • The old text cannot be read after revocation.
  • Cache does not return across scopes
  • References also recheck authorization

Key inspections

  • The authorization identity cannot be taken from the retrieval parameters generated by the model
  • Chunking, reranking, caching, and references all override permissions
  • Understand the different impacts of pre- and post-retrieval filtering on recall and safety margins
