The Codebook - acts as the private key for reconstruction

Fields

version: u32

Version for compatibility

dimensionality: usize

Dimensionality of basis vectors

basis_vectors: Vec<BasisVector>

The basis vectors forming the encoding dictionary Data is projected onto these bases

semantic_markers: Vec<SparseVec>

Semantic marker vectors for outlier detection

statistics: CodebookStatistics

Statistics for adaptive encoding

salt: Option<[u8; 32]>

Cryptographic salt for key derivation (optional)
