P6 is the procurement layer. Most legal AI failures originate in vendor selection, not vendor performance. P6 codifies the Vendor Defensibility Scorecard, the AI Bill of Materials discipline, the sub-processor inventory requirement, and the procurement infrastructure that distinguishes defensible vendor decisions from box-ticking exercises.

Operating outputs: the Vendor Defensibility Scorecard, the AI BoM template, the sub-processor inventory, the procurement playbook, and the Schedule X DPA template.
