/**
* INTEGRATION PATCH FOR STDDEV RANGES
* ====================================
*
* This shows how to integrate the StdDev calculator into the existing
* Direct Calculation button handler in roll_calculator.html
*
* CHANGES:
* 1. Load stddev data from article-data.json when article is selected
* 2. Modify the d-calc button handler to use ranges
* 3. Update Forklift checker to use worst-case weight
* 4. Keep everything backward compatible
*/
// ===================================================================
// PATCH 1: STORE STDDEV IN HIDDEN FIELDS DURING ARTICLE SELECTION
// ===================================================================
// Add this to populateArticleDropdowns_v14() in rollcalc_improvements.js
// In the article selection handler for d-art:
/*
if (match) {
console.log('[Article Select] Found:', match.nr, '- Thickness:', match.thickness, 'Area Weight:', match.area_weight);
// 1. Auto-fill Thickness
document.getElementById('d-th').value = match.thickness;
// 2. Auto-fill Area Weight
if (match.area_weight && match.area_weight > 0) {
document.getElementById('d-aw').value = match.area_weight;
}
// 3. Auto-fill Roll Width
var widthMatch = match.name.match(/(\d+[,\.]\d+)\s*x\s*\d+/);
if (widthMatch) {
var width = widthMatch[1].replace(',', '.');
document.getElementById('de-wi').value = width;
}
// NEW: Store stddev values in hidden attributes
document.getElementById('d-th').dataset.stddev = match.thickness_stddev || 0;
document.getElementById('d-aw').dataset.stddev = match.area_weight_stddev || 0;
