Experiment Plan
- Target asset:
urn:li:dataset:(urn:li:dataPlatform:kafka,payments.authorized_transaction_events,PROD)
- Rationale Explanation: Introduce the unseen digital-wallet channel at the proposed rate and verify that the production encoder's unknown-category behavior remains safe.
- Expected signals: AUC drop, prediction flip rate, inference error rate
