Step 012 — Split-complex boundary algebra
Prime polarity cannot remain a bare classification of fold strata: it must be given an algebra in which the two polar orientations can be projected, compared, and later transported.

Construction role
Prime polarity cannot remain a bare classification of fold strata: it must be given an algebra in which the two polar orientations can be projected, compared, and later transported. The construction therefore passes to the bipolar boundary algebra
, ,
where R_τ denotes the earned scalar/readout algebra available at this stage, not an imported real line. Its idempotents
e_±=(1± j)/(2)
split boundary behavior into orthogonal channels, and the σ-equivariant Boolean sublattice
B_σ(D)=0,e_+,e_-,1
gives the first four-atom boundary grammar. At this stage the atoms are not physical sectors; they are pre-physical channel eigenstates with the pre-physics dictionary 0 null, e_+γ/B, e_-η/C, 1α/D. Physical names such as electromagnetic, strong, and gravitational are assigned only after the Book-III carrier and sector readout are constructed.
What this step earns
Split-complex boundary algebra is made addressable as Step 012 in the fine-grained Construction Spine routing layer.
- Routing scaffold. Detailed earned-output extraction is pending the source-map pass.
What this step does not yet establish
This route exposes the RC3 construction step for inspection. It does not by itself establish peer review, empirical adequacy, or final manuscript-level source closure.
