> The Open Probabilistic Traceback & Origin Engine for Fresh Orchard Produce

OrchardSnacks is an open food origin and supply chain platform that traces the journeys, food miles, cold chain storage timelines, and ecological footprints of perennial orchard produce from grocery store stickers (PLU codes) and country of origin labels.

## The 6 Perennial Orchard Classes
1. **Pome Fruits**: Core-bearing fruits with high controlled-atmosphere storage resilience. (Apples, European & Asian Pears, Quince).
2. **Stone Fruits (Drupes)**: Fragile cold chains vulnerable to chilling injury between 36°F and 46°F. (Peaches, Cherries, Plums, Nectarines).
3. **Citrus Orchards**: Non-climacteric crops requiring 45°F–52°F curing vaults and degreening rooms. (Navel Oranges, Lemons, Limes, Grapefruit).
4. **Tree Nut Crops**: Shaker-harvested seeds dried on orchard floors; year-round shelf life. (California Almonds, Pecans, Walnuts).
5. **Berries & Vine Fruits**: Perennial shrubs and trellised vines with SO2 dual-release pad protection. (Blueberries, Table Grapes, Blackberries).
6. **Subtropical & Tropical Fruits**: High-value crops subject to USDA-APHIS Hot Water Dip quarantine for fruit flies. (Hass Avocados, Mangoes, Figs, Papayas).
