Module math 

Small, dependency-free vector maths used by embedders and stores.

Functions

cosine

Cosine similarity in [-1, 1]; returns 0 if either vector is zero-length.

dot

Dot product of two equal-length slices (unchecked length; extra tail ignored).

from_bytes

Decode a little-endian f32 byte blob back into a vector.

norm

Euclidean (L2) norm.

normalize

L2-normalize a vector in place. A zero vector is left unchanged.

to_bytes

Encode a vector as a little-endian f32 byte blob (for DB storage).
