cosineInt8

cosineInt8(a: Int8Array, scaleA: number, b: Int8Array, scaleB: number): number

Defined in: src/lib/memoryEngine/quantization.ts:119 

Cosine similarity between two Int8-quantized embeddings.

The integer dot product is exact; the per-vector scales cancel because cosine normalizes by both magnitudes — passing scaleA and scaleB is supported for symmetry with the dequantized API but they are mathematically irrelevant when both vectors share the same quantization scheme. They are still validated to catch zero-magnitude (zero-vector) inputs cleanly.

Returns 0 when either vector is zero or dimensions differ. Result is clamped to [-1, 1] to absorb floating-point error from sqrt.
