citadeldb-vector

Vector search for the Citadel encrypted embedded database engine. Provides the VECTOR(N) SQL type, distance operators (<-> L2, <#> inner product, <=> cosine), and a PRISM-backed filtered approximate-nearest-neighbor index that reads through Citadel's encrypted page storage, so the index is encrypted at rest like every other page.

This crate is part of the Citadel workspace. For SQL vector queries depend on the main citadeldb crate; for agent memory see citadeldb-mem.
