      operationId: scan
      summary: Scan
      description: 'Scans up to 1000 patient merge updates. The since query parameter is inclusive, and the result list is ordered by updatedAt ascending.


        **Polling Pattern:**

        To continuously poll for updates without gaps:

        1. Make your initial request with a `since` timestamp (e.g., `since=2020-01-01T13:00:00.000Z`)

        2. The API returns 100 by default and up to 1000 patient merge records, sorted by `updated_at` ascending

        3. Find the `updated_at` value from the last record in the response

        4. Use that `updated_at` value as the `since` parameter in your next request

        5. Repeat steps 2-4 to ingest updates until you receive an empty list


        **Important Notes:**

        - The `since` parameter is inclusive, so you may receive the last record from the previous batch again (you can deduplicate by ID and version)

        - All patient merge records include `updated_at`, `id`, `version`, `deactivated`, and `updating_user` fields for tracking changes

        - Timestamps have millisecond resolution for precise ordering'
