BIFSG Insurance Proxy Bias Threshold Test (Colorado SB 21-169)

Tests BIFSG proxy bias thresholds under Colorado SB 21-169 / Reg. 10-1-1 for insurance AI models. ZERO PII: accepts aggregate regression outputs only (p-value, marginal effect %, premium delta per $1,000 face) -- no individual applicant data, proxy scores, or demographic identifiers enter this kernel. Statistical prong: p < 0.05 AND marginal effect >= 5 percentage points. Premium prong (standalone): premium >= 5% above average per $1,000 face. Annual attestation due December 1: anchor execution_hash at anchor.ainumbers.co/mcp (COMPOSE, do not rebuild). Disambiguates from compute_disparity_metrics (art-229): that node applies ECOA/HMDA 4/5ths adverse impact rule for lending; this node applies Colorado SB 21-169 p-value and premium-rate bias tests for insurance AI.
