Case 02 / Compliance engine · award-winning
Guardian
A compliance console that reads a supplier's messy dossier and blocks non-compliant cosmetic listings against real Vietnamese law — verdicts come from a deterministic engine, never the LLM.
Demo
The rule
Exactly one LLM call per document — extraction only. The verdict is a pure function running six checks. Verdicts never come from the LLM.
Build notes
The 48-page sweep
Swept 48 product pages from the client's own live site through the exact production matcher: 45 clean, 3 correctly flagged — one violation buried in body copy — zero false positives.
Law as data, not prompt text
9 policy clauses each citing Circular 06/2011/TT-BYT or the 2012 Advertising Law, an 80-row recall watchlist from a real DAV decision, and a 5-substance banned-ingredient screen.
The Vietnamese matcher
Fixes a real false-positive class: 'trị' alone fires on 'giá trị' in invoices — so it matches full claim phrases, plus a diacritic-stripped twin for OCR'd scans.
Concurrency done right
Concurrent review runs are serialized with a Postgres advisory lock that stays correct through pgBouncer, with a 5-minute staleness window to recover crashed runs.
