Pre-registration for assessment validation studies — should it be mandatory?

Strong yes. The vendor incentive structure makes post-hoc validation almost guaranteed; pre-registration is the cheapest way to interrupt that. The harder question is who enforces it. Industry self-regulation has failed in every adjacent domain.

Agree on the principle. Disagree on "mandatory" — it raises the cost-of-entry in a way that locks in incumbents. I'd start with disclosure norms enforced by buyers, not regulators.

Vendor-side perspective: we pre-register and we lose deals to competitors who don't because their numbers look cleaner. There needs to be a buyer-side norm before this becomes a competitive feature instead of a competitive liability.
