Module coupling 

Coupling — Gravity-weighted Kuramoto stepping for substrates.

The coupling function K_ij = K_base × G × cos(sim(e_i, e_j)) makes semantically similar atoms synchronize faster. This is the geometric kernel: the coupling IS the kernel function on the semantic manifold.

Uses the existing phase::kuramoto::kuramoto_step for the actual phase evolution, but computes the adjacency matrix from embeddings.

Structs

AudioMetrics

Audio metrics passed from JS via SharedArrayBuffer.

Functions

coupled_step

Perform one coupled Kuramoto step on all atoms in the substrate.

gravity_coupling

Compute gravity coupling between two atoms using embedding similarity. K_ij = K_base × gravity_scale × max(0, cos(sim(e_i, e_j)))
