Function declared_dimension 

Source 
pub async fn declared_dimension(
    conn: &Connection,
    model: &ModelName,
) -> Result<usize>
Expand description

The dimension a registered model’s table declares, read from the schema.

The crate keeps no registry of its own. F32_BLOB(768) in the column type is the declaration, PRAGMA table_info reports it verbatim, and reading it back means the Rust-side dimension check and the storage-layer one cannot disagree — there is only one number. Keeping a HashMap<model, dim> beside the database would be the same mistake D-035 fixed in archive(): a second hand-maintained description of a set the schema already defines.
