1.1.3 - Fix impossible calorie readings from the scanner FIXED - Barcode scanner sometimes recorded absurd calorie values (e.g. a Juice Monster showed 118,000 kcal). Root cause: some entries in the Open Food Facts database have typos - contributors occasionally enter energy in calories instead of kilocalories, or drop a decimal point, so the wrapper says 120 kcal but the database record says 118,000. The 1.1.2 fix taught the scanner to prefer per-serving values but still trusted whatever number was in the field. Now the scanner cross-checks calories against the reported protein, carbs, and fat using the standard 4-9-4 rule (4 kcal per gram of protein and carbs, 9 kcal per gram of fat). Values that are more than 3x what the macros can account for are rejected, and the scanner falls back to USDA data for that product.
