Module vector 

Vector operations — cosine similarity, hybrid merge, serialization.

Extracted from the former memory module and now used by crate::tools::SearchArchivedTicketsTool for hybrid FTS+semantic search. crate::embedder::Embedder produces embeddings that are stored as blobs in the tickets table and deserialized via bytes_to_vec during search.

Structs

ScoredResult

A scored result for hybrid merging

Functions

bytes_to_vec

Deserialize bytes to f32 vector (little-endian)

cosine_similarity

Cosine similarity between two vectors. Returns 0.0–1.0.

hybrid_merge

Hybrid merge: combine vector and keyword results using Reciprocal Rank Fusion (RRF).

vec_to_bytes

Serialize f32 vector to bytes (little-endian)
