Clean, prepare and conduct initial analytical assessment of approximately 30 additional candidate panel survey datasets for potential inclusion in the ILO multi-country resource on transitions between informal and formal employment. Review panel structures, identifiers, rotation schemes, survey years and availability of variables required to operationalize informality/formality. Harmonize core labour-market variables, prepare panel-ready and transition files where feasible, conduct descriptive and diagnostic checks, and document panel survey datasets retained, excluded or requiring restricted use. Provide harmonization code, country-level READMEs, QA logs and a consolidated feasibility tracker
