OpenFoodFacts is the sole barcode lookup. Poor coverage for store-brand, regional, and specialty products. Users dropped into manual entry with no assistance on miss.

Implementation: Resolver chain (like LLM fallback in expiration_predictor.py). Primary: OFF. Fallback 1: UPC Item DB (free, low-volume). Fallback 2: USDA FDC branded foods by barcode. Log miss rate per source.

Tier: Free (chain); Paid (premium barcode APIs).

Implemented in commit 0de6182.

Fallback chain: OFFs → Open Beauty Facts → Open Products Facts. All three share the same API format. When all miss, the frontend switches to manual entry mode automatically instead of silently failing.
