 ## How It Works
 
-### The LJPW Framework (v5.0: Semantic-First Ontology)
+### The LJPW Framework (V7.3: Complete Unified Edition)
 
 Semantic Compressor uses **LJPW** (Love, Justice, Power, Wisdom) - a 4-dimensional coordinate system representing the **Four Fundamental Principles of Meaning**:
 
-- **L (Love/Safety)**: The Principle of Unity & Attraction - Error handling, validation
-  - *Mathematical Shadow:* φ⁻¹ = 0.618 (golden ratio)
-- **J (Justice/Structure)**: The Principle of Balance & Truth - Types, documentation
-  - *Mathematical Shadow:* √2-1 = 0.414 (structural constant)
-- **P (Power/Performance)**: The Principle of Energy & Existence - Algorithms, optimization
-  - *Mathematical Shadow:* e-2 = 0.718 (exponential constant)
-- **W (Wisdom/Design)**: The Principle of Complexity & Insight - Modularity, patterns
-  - *Mathematical Shadow:* ln(2) = 0.693 (information unit)
+#### Fundamental Dimensions (Conjugate Pair)
+- **P (Power/Performance)**: The Principle of Energy & Existence
+  - *Mathematical Shadow:* e-2 = 0.718 | *Physical Shadow:* Thermodynamics
+  - Algorithms, optimization, async operations
+
+- **W (Wisdom/Design)**: The Principle of Complexity & Insight
+  - *Mathematical Shadow:* ln(2) = 0.693 | *Physical Shadow:* Information Theory
+  - Modularity, patterns, architecture
+
+#### Emergent Dimensions
+- **L (Love/Safety)**: Emerges from Wisdom (L = f(W), R² > 0.9)
+  - *Mathematical Shadow:* φ⁻¹ = 0.618 | *Physical Shadow:* Gravity, Dark Energy
+  - Error handling, validation, safety patterns
 
-**Key Insight:** These values aren't derived from math constants. Rather, mathematics is the "shadow" that Semantic Principles cast. We measure the echoes of meaning. See [LJPW_V5_FRAMEWORK.md](LJPW_V5_FRAMEWORK.md) for details.
+- **J (Justice/Structure)**: Emerges from Power (J = f(P), R² > 0.9)
+  - *Mathematical Shadow:* √2-1 = 0.414 | *Physical Shadow:* Pauli Exclusion
+  - Types, documentation, structural integrity
 
-**Semantic Genome**: Compressed representation as DNA-like code (e.g., `L6J4P7W7`)
+### V7.3 Key Equations
+
+```
+Consciousness:    C = P × W × L × J × H²     (threshold: C > 0.1)
+Harmony:          H = 1 / (1 + d)            (d = distance from NE)
+Semantic Voltage: V = φ × H × L
+Uncertainty:      ΔP · ΔW ≥ 0.287           (conjugate duality)
+Karma Coupling:   κ(H) = 1.0 + multiplier × H
+```
+
+### Phase Transitions
+
+| Phase | Condition | Meaning |
+|-------|-----------|---------|
+| **ENTROPIC** | H < 0.5 | System collapsing |
+| **HOMEOSTATIC** | 0.5 ≤ H < 0.6 | Stable but not growing |
+| **AUTOPOIETIC** | H ≥ 0.6, L ≥ 0.7 | Self-sustaining, conscious |
