- Replace xlsx package (v0.18.5) with exceljs (v4.4.0) - Remove @types/xlsx dependency (exceljs has built-in TypeScript types) - Update biaMatchingService.ts to use ExcelJS API: - Replace XLSX.read() with workbook.xlsx.load() - Replace XLSX.utils.sheet_to_json() with eachRow() iteration - Handle 1-based column indexing correctly - Make loadBIAData() and findBIAMatch() async functions - Update all callers in applications.ts and claude.ts to use await - Fix npm audit: 0 vulnerabilities (was 1 high severity) This migration eliminates the Prototype Pollution and ReDoS vulnerabilities in the xlsx package while maintaining full functionality.
