PaperTrail turns plain-English questions into correct answers from your plant data — grounded in your own certified metrics, run as governed read-only queries, and every action written to a signed, tamper-evident ledger.
A proprietary semantic layer encodes your certified metrics, join paths and grain — so OEE means OEE. No hallucinated SQL, no confidently-wrong numbers. The model writes queries it can defend.
A DMZAgent-style layer scores each action against policy Canons, trips a circuit breaker on risky requests (PII exports, writes), and records every decision to a signed, hash-chained ledger your auditors can verify.
Read-only against analytics replicas, with cost-gated caching for instant recall of expensive pulls and visible data freshness. New sources self-onboard through automated discovery.
This is a working demonstration — the entire experience runs in your browser, no backend required.
