langfuse-data-boundary-auditor

Audit supplied Langfuse observation payloads for unapproved fields, incomplete cursor coverage and retention evidence gaps. Separate project retention from Cloud access windows and dataset/audit/external-copy scope. Use when reviewing this evidence. Trigger with "review a Langfuse debug export", "did anonymization leave metadata?" or "does retention cover all these Langfuse records?".

# Langfuse Data Boundary Auditor

## Overview

Compare supplied observation response fields with an explicitly reviewed owner
policy and identify project/retention/coverage gaps. Unknown fields, empty
containers and nested metadata are still data. A matching field policy is not
anonymization, permission to publish, proof of deletion or legal compliance.

This operator produces an evidence ledger. It never creates an export, rewrites
customer data, rotates credentials, changes retention or deletes records.
