AI Letters #33 - We Built Traceprop: Finally, an ML Audit Trail That Answers the Regulator's Question
· 12 min read
We spent months auditing ML pipelines across regulated industries. Every single one had the same gap: source files on one side, model predictions on the other, and nothing connecting them.
