What approach do experts recommend for the Nachweisgesetz and essential contract terms in the funnel?

For the Nachweisgesetz (Verification Act) and essential contract terms in the funnel, a versioned mandatory field model for core conditions is the most robust approach. Decision criterion: fewer inconsistencies between listing, offer, and contract over at least two review cycles. Specifically: define core conditions in the portal; align listing, offer, and contract logic. (Sources: Destatis Labour Market, BA Beschaeftigung Statistik)
