title: Add pilot-critical Customer BP validation rules

source_evidence: The deterministic pilot readiness gate reports 31.2% validation-rule
  coverage for the Customer BP reference model, below the 40% pilot threshold. Adding
  two rules for the high-risk tax number and foundation date attributes raises the
  model to 43.8% without claiming that every attribute is fully governed.

# Customer BP pilot validation coverage

This proposal intentionally closes the minimum evidence gap required for a pilot-ready
reference model. Country-specific formats and the cutover date remain review inputs; no
AI-generated rule is treated as an executable control without human review.
