Campaign activity generates events across channels:

* impressions
* clicks
* conversions
* on-chain actions

Each event is:

* signed locally
* timestamped
* streamed into a unified event layer

For every event, two receipts are generated:

* **Usage Receipt** records what data was used, under which policy, and at what privacy cost
* **Result Receipt** records anonymized outcomes such as reach and conversions

Only cryptographic commitments are stored on-chain. Detailed records remain in their original domains for audit.

**Output:** → verifiable, tamper-proof event records (VUR)
