+# TariffWise
+
+AI tariff classification for footwear. A model reads the product description and runs an adaptive interview. A deterministic engine walks the 2026 HTS Chapter 64 tree, built from the published schedule, and assigns the ten digit code with its full derivation. Unresolved legal conditions route to expert review.
+
+Decision support only. Not legal advice.

+"""TariffWise AI layer. The model does the language work.

+The model has three jobs. It extracts facts from the user's description.
+It phrases the engine's named gap as a plain question. It reads each
+answer back into schedule terms. The engine makes every decision. No
+model output assigns a code.
+
+Provenance is recorded per fact. A fact is user_stated when extracted
+from the user's own words, and answered when it came from an interview
