A relief offer with hot rice at 52 °C is blocked by two packs

The disaster-kitchen flow records lentils, rice and cooked rice trays hot-held at 52 °C. The basic pack and the care pack each block the hot line; a nutrition pack has nothing to say about temperature.

الخطوات

  1. With no pack named the hub applies basic-nutrition-food-safety: one block finding on line 3. humanitarianCheck

  2. The care pack has its own hot-hold rule for vulnerable groups. humanitarianCheck

  3. Both packs together: two findings on the same line. humanitarianCheck

  4. The sodium-reduction pack alone: no temperature rules, no findings. humanitarianCheck

  5. Had this line come in by SMS, the gateway would have refused to list it before any document existed. parseSms

النتيجة

You have seen a block finding with its rule id, severity and the line it concerns. Next: scenario 076 compares it with an offer whose readings pass.
