## Proposed Change

- Asset: `urn:li:dataset:(urn:li:dataPlatform:kafka,payments.authorized_transaction_events,PROD)`
- Source column: `payment_channel`
- Scenario: new-digital-wallet-channel
- Request: Five percent of payments will begin using a new payment_channel category named digital_wallet.
- Trigger event: `evt-95f298cb-c57c-4efc-a974-b0557f5bb086`
- Trigger source: `payment-platform-release-agent`

### Evidence URNs

- `urn:li:dataset:(urn:li:dataPlatform:kafka,payments.authorized_transaction_events,PROD)`
- `urn:li:dataset:(urn:li:dataPlatform:postgres,fraud.realtime_payment_features,PROD)`
- `urn:li:mlFeature:(realtime_payment_risk_features,payment_channel)`

## 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
