1Access
Application-owned authorization
Treat the Pinecone API key as service authentication, not end-user authorization. Resolve user, tenant, case, and source permissions outside Pinecone, construct namespace and metadata filters in trusted server-side code, and test that every disallowed cross-boundary query returns no content.
2Freshness
Version-aware ingestion
Use deterministic record IDs, source-version markers, and idempotent jobs. Reconcile inserts, updates, revocations, and deletes against the source rather than treating a one-time index load as complete.
3Context
Corpus quality gate
Require an owner, effective status, access classification, and provenance before content can enter a production namespace. Quarantine malformed, orphaned, or conflicting records.
4Quality
Retrieval evaluation set
Maintain representative queries with expected evidence, prohibited evidence, and acceptable no-answer behavior. Measure retrieval coverage, ranking quality, filter correctness, corrections, latency, and cost.
5Evidence
Query and index observability
Trace namespace, filters, query strategy, returned record IDs, scores, source versions, reranking, latency, errors, and the downstream disposition without leaking protected content into logs.
6Recovery
Recoverable index changes
Test schema, embedding, chunking, and retrieval changes in a separate index before cutover. Where the plan and index type support backups, account for the non-queryable snapshot, its same-project, cloud, and region restore boundary, and the possibility that records written within the preceding 15 minutes are excluded.
