5 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.

The evidence overlap.

Both records have documented values for Product type, Technical setup, Published numeric pricing, Checked within 30 days, Retained price snapshot. Matching availability does not measure behavior under your call conditions.

Run the same booking, tool failure and unsuccessful human-transfer cases. Record both outcomes and billable units before signing a deployment agreement.
