Crate dimvexa_data 

The unit table of dimvexa, compiled from audited TOML at build time.

The source of truth is data/units/*.toml (inside this crate): each unit carries an exact rational factor, an exactness flag (defined or measured), a cited source and a note, and has at least one golden test vector in data/vectors/. cargo xtask validate-data enforces this.

let reg = dimvexa_data::registry()?;
let c = reg.conversion("psi", "Pa")?;
assert!((c.apply(1.0) - 6894.757_293_168_361).abs() < 1e-9);
