The Fifth Coordinate — the Θ/θ Dictionary
Year: 2026
Type: preprint
Abstract: Derivation note, R&D Division, November 8, 2026. Successor to 'The Fifth Coordinate — the Bundle Construction' (November 8, 2026), which proved a uniqueness count — the corpus owns exactly one phase field, one seated twist, and one circle bundle — and sharpened the dictionary between the lineage twist Θ of Bounce Theory II/III and the phase θ of the torsion sector into a forced fork: either Θ is the bundle's axial holonomy read at slice scale, or Θ lives in a structure the corpus has not yet written. This note extracts every load-bearing Θ statement in Bounce Theory I–III and every load-bearing θ statement in FRONT-A, tests the first horn against each, and finds no contradiction. The dictionary: Θ at an epoch hypersurface is the signed principal value of the difference of the axial holonomy of the torsion connection S between that epoch and the home epoch — by Stokes' theorem, the flux of the connection's curvature through the axis worldsheet between the two epochs. The integer part of the holonomy is the lineage winding number (constant, invisible mod 2π); the reported small angle is the fractional part's epoch difference. The craft-scale reading χ and the slice-scale reading Θ are the open-path and closed-loop readings of one field; neither is the other. The identification is graded CONSTRAINED (unique in form; not derived from an action). The value Θ(recombination) is NOT DERIVED: the frame owes a law for the worldsheet flux, whose integrand and surface this note names. The fifth coordinate remains CONSTRAINED — charge (iii), the dictionary, is discharged; charge (ii), the readout, stands open. Three falsifiers are printed (F-D1–F-D3), including an empirical one: a measured rotation that accumulates along the trip would kill the boundary-difference form and this dictionary with it. Quantities drawn from simulation budgets in the parent notes (σ_χ ≤ 0.0667 rad) are SIMULATED, NOT MEASURED.
