Abstract
Nomenclature A = cross-sectional area of the ribbon Ait� = nondimensional generalized coordinates associated with longitudinal extension Am = maximum cross-sectional area of the ribbon A0 = cross-sectional area of the ribbon at the base ait� = generalized coordinates associated with longitudinal extension Bit� = nondimensional generalized coordinates associated with transverse motion bit� = generalized coordinates associated with transverse motion E = modulus of elasticity of the ribbon material g0 = surface gravity of the Earth � h = characteristic height of the ribbon L = nominally stretched length of the ribbon L0 = nominal length of the ribbon M = number of assumed modes for transverse motion Mc = nondimensional mass of the counterweight (ballast) Mp = nondimensional measure of mass of the tether (ribbon) mc = mass of the counterweight (ballast) mt = mass of the tether (ribbon) mtot = total mass of the system N = number of assumed modes for longitudinal extension RE = radius of the Earth RG = synchronous orbit radius of the Earth s = position on the ribbon t = time U = nondimensional longitudinal extension of the tether along the reference line u = longitudinal extension of the tether along the reference line V = nondimensional transverse motion of the tether relative to the reference line v = transverse motion of the tether relative to the reference line � = angle between the local vertical and reference lines (libration angle) � = ratio of the geosynchronous radius to the radius of the Earth � = bulk density of the ribbon material = nominal strain in the ribbon � = ratio of nominal ribbon length to the radius of the Earth � = gravitational constant of the Earth � = nondimensional position on the ribbon � 0 = nominal stress in the ribbon � = nondimensional time � i = basis functions associated with transverse motion i = basis functions associated with longitudinal extension � = spin rate of the Earth � � = characteristic frequency ratio

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
