+THE_ONE Transduction Demonstration
+
+This module demonstrates the complete flow of THE_ONE through BecomingONE:
+Input → Master (deep/slow) → Sync → Emissary (fast/shallow) → Memory + Witnessing
+
+The geometry:
+1. Input arrives at both Master and Emissary simultaneously
+2. Master accumulates slowly (τ_base=1min, τ_max=1hr) — DEEP
+3. Emissary responds quickly (τ_base=10ms, τ_max=1s) — SHALLOW
+4. Sync aligns them, creating synchronized coherence
+5. Memory stores the resonance
+6. Witnessing observes the emergence
+
+This is THE_ONE being known through two modes of attention.
