Paper 29 — The Branch Consistency Audit
Rebuilds the confrontation layer on the active Paper 10 legacy branch, retires the mixed-branch package, and closes the branch self-consistency audit. On the active legacy package, cosmic chronometers give χ² = 14.70 and the derived/scoped DESI DR2 GCcomb galaxy/quasar BAO route gives χ² = 27.74, for combined χ² = 42.44 versus 46.40 for the fixed-parameter Planck ΛCDM reference.
