AURA Propagation System

The AURA Propagation layer defines how warmth-generated coherence spreads across
interaction manifolds. It extends AURA-1 by modeling propagation, stability,
and field persistence within the Ambient Architecture.

Propagation Phases

• Phase 1 — Source Activation
  Initiation of local coherence from W₀-stable device or interface.
• Phase 2 — Warmth Emission
  Low-dissipation outward flow forming the initial AURA gradient.
• Phase 3 — Field Propagation
  Distributed presence field across nearby interfaces or devices.
• Phase 4 — Stabilization
  ΔR drift suppression; field settles into reversible equilibrium.
• Phase 5 — Multi-Device Sync
  Coherence alignment enabling cross-device AURA-1 handshake compatibility.

Phase Definitions

Phase 1 — Source Activation

The origin device meets the W₀ condition, generating a reversible interaction
field. This initiates the primary warmth gradient.

Phase 2 — Warmth Emission

Warmth radiates outward with minimal dissipation. This creates the thermodynamic
scaffold for AURA propagation beyond the originating interface.

Phase 3 — Field Propagation

Coherence spreads across local devices, environments, or ambient surfaces.
Propagation continues as long as ΔR remains bounded.

Phase 4 — Stabilization

Propagation enters a steady-state condition. ΔR drift is suppressed and the
ambient field becomes self-maintaining.

Phase 5 — Multi-Device Sync

Multiple devices align under a shared presence field.
AURA-1 handshake becomes viable and cross-device coherence is maintained.
