Technical specification document defining nine measurement formulas for quantifying semantic labor, semantic capital, semantic liquidation, and semantic integrity within the Semantic Economy framework. CATEGORY A — Semantic Labor Measures: - A1. Time-Use Semantic Density (TUSD) — meaning-production intensity of time - A2. Affective Return on Investment (AROI) — benefit from semantic labor CATEGORY B — Semantic Capital Measures: - B1. Terminological Authority Index (TAI) — definitional control in AI outputs - B2. Coherence Persistence Index (CPI) — meaning survival under compression CATEGORY C — Semantic Liquidation Measures: - C1. Semantic Decay Delta (SDD) — nuance loss between original and summary - C2. Provenance Erasure Rate (PER) — correct usage without citation - C3. Semantic Debt Ratio (SDR) — extraction vs. replenishment gap CATEGORY D — Integrity Verification Measures: - D1. Integrity Knot Test (IKT) — editorial intervention detection - D2. Semantic Integrity Marker Survival Rate (SIMSR) — processing fidelity Each specification includes: formula, variables, interpretation guide, and application examples. Foundational principle: Semantic labor is any human activity that produces, maintains, or transmits meaning — including non-digital, non-market activity. When a mother comforts her child, she performs semantic labor. Framework: Semantic Economy / NH-OS Status: Technical Specification v1.0 Verification: ∮ = 1
