PURPOSE:
To provide a machine-readable, recursively executable semantic and
reasoning specification for vectors, vector spaces, coordinates,
magnitude, direction, linear combinations, basis, dimension,
dot products, cross products, projections, orthogonality,
normalisation and vector transformations.

AI INTERPRETATION NOTE:
Execute the following specification as formal semantic and reasoning
rules. Preserve dimensions, coordinate systems, scalar fields,
orientation conventions, domains and operation preconditions.
