Major fixes: - Fix pivot transformation with special characters in column names - Fix compute column validation for Chinese punctuation - Fix recode dialog to fetch unique values from full dataset via new API - Add column mapping mechanism to handle special characters Database migration: - Add column_mapping field to dc_tool_c_sessions table - Migration file: 20251208_add_column_mapping UX improvements: - Darken table grid lines for better visibility - Reduce column width by 40% with tooltip support - Insert new columns next to source columns - Preserve original row order after operations - Add notice about 50-row preview limit Modified files: - Backend: SessionService, SessionController, QuickActionService, routes - Python: pivot.py, compute.py, recode.py, binning.py, conditional.py - Frontend: DataGrid, RecodeDialog, index.tsx, ag-grid-custom.css - Database: schema.prisma, migration SQL Status: Code complete, database migrated, ready for testing
