Wave C: Structural Map of Multi‑System Coherence

Wave C formalizes the architecture of multi‑system coherence: how alignment, drift, and reorganization propagate across interacting systems without central control. It provides the structural map for the Second Triad (Objects 4–6), revealing their downstream signatures while preserving all upstream operators. This document situates Wave C as the bridge between internal coherence (Wave B) and collective‑scale phenomena. It outlines the geometry through which coherence becomes inter‑systemic: cross‑agent gradient detection, longitudinal drift across carriers, and distributed reorganization under tension. Wave C shows how these signatures appear across biological, cognitive, ecological, symbolic, and institutional substrates, forming a unified multi‑system field. The Structural Map establishes the conceptual boundaries, invariants, and relational dynamics that govern all Wave C papers. It provides the minimal scaffolding required to understand how coherence propagates across agents, how collective structures stabilize or dissolve, and how downstream systems express the physics of Objects 4–6 without exposing their mechanisms. Wave C is the first layer where coherence becomes visible between systems. This map defines its geometry.
