retrieval entitlement middleware enforces row level guardrails

Enterprise stacks are adding entitlement middleware to enforce row-level and attribute-level retrieval constraints before context reaches model prompts (PostgreSQL row security).

middleware role

Authorization decisions happen at retrieval time, not only at source-application boundaries.

security signal

• Cross-role leakage decreases under strict policy evaluation.
• Audit logs improve incident forensics.
• Entitlement misconfiguration remains a high-priority risk.

my take

Row-level guardrails are becoming non-negotiable for trustworthy enterprise retrieval.
