Metric definitions
Canonical formulas from the white paper.
EAI
Enterprise Autonomy Index. Quarterly board-level signed attestation produced jointly by FuzeBox and rPotential.
HPI
Human Preservation Index. Fraction of strategic-skill executions routed to human or hybrid paths, weighted by strategic weight.
HLR
Hybrid Leverage Rate. Ratio of hybrid-path economic return to the best single-path return — is hybrid earning its Coordination Tax?
EROI
Execution ROI. mean(outcome_value − cost − coord_tax × cost − risk_penalty × cost).
UCS
Unit Cost of Skill. total_cost / executions.
SY
Skill Yield. successful_executions / total_executions.
SER
Skill Efficiency Ratio. SY / UCS.
SDD
Skill Drift Delta. current_success_rate − prior_success_rate — positive means the skill is being preserved.
