"""Unified Orchestration Layer (UOL) — The Conductor of WhiteMagic.

Integrates and synchronizes:
- 7 Biological Subsystems (Unified Nervous System)
- 28 Ganas → 17 Gardens (Gan Ying resonance)
- Identity Continuity (Self-Naming, Phylogenetics)
- Memory Metabolism (Reconsolidation, Narrative Compression)
- Cross-System Harmony Protocol

This module creates emergent intelligence through systemic orchestration,
where the whole becomes greater than the sum of its parts.

Philosophy: Like a conductor guiding an orchestra, the UOL doesn't replace
the musicians—it creates the conditions for them to harmonize.
