Struct ShardEmbedding 

pub struct ShardEmbedding(pub [f32; 8]);

👎Deprecated:

JL projection at m=8 is mathematically unsound (Issue 139). Zero runtime consumers. Use region centroids for shard similarity.

Low-dimensional projection of NeuronShard style_weights for fast similarity search. Produced by Johnson-Lindenstrauss random orthogonal projection. 8 × f32 = 32 bytes — fits in cache line, suitable for SIMD cosine similarity.

Plan 230: Shard Embedding Projection — modelless linear weight-to-vector.

Deprecated

Mathematically unsound at m=8 — violates the JL lower bound by over 200×. See Issue 139 / Plan 230 close-out note.

Implementations

impl ShardEmbedding

pub const ZERO: Self

pub const DIM: usize = 8

pub fn cosine_similarity(&self, other: &Self) -> f32

Cosine similarity between two embeddings. Uses SIMD dot-product and SIMD sum-of-squares for the normalization.

pub fn dist_sq(&self, other: &Self) -> f32

Euclidean distance squared between two embeddings. Uses SIMD-accelerated fused-subtract-accumulate.
