Prior recovery within 0.001 of planted value
Description
Infrastructure validation: a known prior (β = 0.35) was planted and the engine recovered it. This confirms the engine’s prior-recovery pathway produces unbiased estimates under controlled conditions.
Methodology
Simulated 100 learners across 20 items with a planted prior of β = 0.35. The engine’s posterior estimate converged to β = 0.351, within 0.001 of the planted value.
Reference
Internal infrastructure validation. No external reference.
This is a synthetic recovery, not a replication of the original study. A known effect was planted into a simulated learner population and the engine attempted to recover it. Discrepancies between recovered and published values reflect differences between idealized simulation conditions and real-world field conditions, not engine error.
