The Shiab Operator: Definition and Geometric Meaning
Shiab is the Einstein projection rebuilt out of transport, wedge, and $\ast_Y$—so gauge symmetry survives.

The Ricci trace is a perfectly good move on tensor curvature—until curvature lives in $\mathrm{ad}(P_H)$.
Two bad transformation laws, one good variable.
Choosing an affine origin (without adding structure) so transport becomes well-defined.
Connections don't form a vector space, and that single fact quietly forces a bigger symmetry.
Fields don't live on spacetime by default—they must survive pullback from the observerse.
Axial torsion is the engine that distinguishes chirality, drives overlap physics, and deforms geometry from the inside.

We introduce a single scalar that controls how the ambient geometry breathes along unobserved directions.

The immersion is an observation map that carves spacetime into the ambient geometry and defines what survives pullback.
In this post, we zoom out to the 14D ambient space Y, where Geometric Unity actually lives. We’re not compactifying, slicing, or bolting on extra fields. Instead, everything we observe—fields, particles, interactions—is a consequence of how 4D spacetime immerses into a larger, structurally rigid arena.
This post defines observables in Geometric Unity: quantities that are invariant under transport symmetry and stable under pullback.
Once torsion is recognized as a coordinate on connection space, geometry becomes a transport problem.
