Realization-fiber coherence eighth rung
Question
Does equal SCC certification leave a residual comparison problem large enough to require another canonical tower rung?
Claim boundary
The exact finite witness proves incompleteness of profile, kernel, and Gramian data for constructor equivalence. It does not classify physical or theta/Tate realization fibers.
Disposition
The canonical tower now has eight base rungs, ending in A7 realization-fiber coherence, with adjacent reconciler C1_6 law-to-realization fiber comparison. The interval flag expands from 28 to 36 cells and from 42 to 56 face maps; all 36 theta/Tate secondary overlay slots are present. An exact two-dimensional C_2 witness places two systems in the same strongest SCC profile with identical observer and Gramian but different constructor characters and no invertible intertwiner. The renderer now correctly admits the canonical v2 schema.
