  "reportHeader": {
    "title": "Monthly Sales Report",
    "subtitle": "Calculated: {MONTH(TODAY())} {YEAR(TODAY())}"
  },
  "parameters": [
    {
      "name": "country",
      "type": "select",
      "cascadeConfig": { "optionsUrl": "/api/countries" }
    },
    {
      "name": "region",
      "cascadeConfig": {

      "type": "html",
      "content": "Products in {category}/{subcategory}"
    }
  ]
}

🔄 Framework Behavior Consistency

Calculated Fields

FormRenderer:

// Recalculate on every field change
handleFieldChange → recalculateFields → updateFormData

DashboardRenderer:

// Recalculate on refresh interval or filter change
handleRefresh | handleFilterChange → recalculateWidgets → updateDashboard

ReportRenderer:

// Calculate once during report generation
generateReport → calculateTotals | calculateSummaries → renderReport

ContentRenderer:

// Calculate once during render (if filters change, recalculate)
render → calculateContent | handleFilterChange → recalcContent

Cascade Selects

All Renderers:

// Load parent field options on mount
// Load child options when parent changes
// Cache options for 5 minutes
// Lock values during submission/generation

Async Validation

FormRenderer:

// Validate on blur (debounced 500ms)
// Validate on change (sync rules only)
// Validate all on submit

DashboardRenderer:

// Not primary concern
// Widgets don't require form submission validation

ReportRenderer:

// Validate parameters before generation
// No ongoing validation during report display

ContentRenderer:

// Validate embedded forms only
// Not applicable to static content

Repeater Discovery

FormRenderer:

// Discover templates on mount
// Generate from database schema if not provided
// Allow add/edit/delete operations

ReportRenderer:

// Discover templates for detail sections
// Display read-only rows
// No add/edit/delete

DashboardRenderer & ContentRenderer:

// Not applicable - no repeater sections

✅ Consistency Testing Checklist
