The Global Coherence Constructor Is the Simplicial Braid Object
The arity-indexed pure braid groups form one simplicial object
with deletion face maps and strand-doubling degeneracy maps. Brunnian classes are its simultaneous face-kernel elements, but raw Brunnian cycles are not yet irreducible residues. Authorized higher fillings generate a boundary-like symmetric-commutator subgroup.
For spherical braids and , the terminal quotient is
Therefore the unbounded coherence hierarchy is organized by a single graded constructor. Its true obstructions are homotopy residues after fillable cycles are removed. This separates a facewise-invisible cycle from a genuinely unfillable class.
Geometric realization classifies the residue but grants no executable observation port; that still needs a source-authorized readout map.
