Reads a customs declaration packet (commercial invoice, packing list,
customs declaration, certificate of origin) and audits it before filing:
a deterministic checklist audit per document plus a cross-document packet
audit that flags the mismatches that stall clearance (weights, HS code,
origin, currency, Incoterms). Every finding cites the exact document and
line; when the packet does not contain a value, Tamga reports it as not
found instead of guessing.
FastAPI + SQLite backend (TF-IDF retrieval with optional dense embeddings,
reranking and OCR, all gracefully degrading), React/Vite frontend with a
guest demo, evidence reports, and an anti-hallucination evaluation suite
(59 tests, golden dataset, A/B harness).
