- Claims [[claim-internal-negotiation-dominates]], [[claim-guardrails-fail]], [[claim-upfront-consensus-destroys-value]], [[claim-ai-replaces-routine-negotiation]].
- The prescriptive apparatus: [[concept-deal-value-board]], [[concept-consultation-funnel]], [[concept-internal-side-deals]], [[concept-market-standard-default]], [[concept-business-plan-mandate]], and action items [[action-audit-contract-history]], [[action-strip-commitment-authority]], [[action-draft-business-plan-mandates]], [[action-implement-dvb]].
