G0: copied inputs and the unchanged stop

Only XIV-F, XIV-E, XIV-D, XIV-C, XIII-C, XIII-B, XII-E, and XII-C are analytic manuscript inputs. The new proofs below are conditional on their stated handoffs. They do not verify every predecessor premise anew.

Quoted passages are copied from the supplied manuscripts. Displayed formulas are recorded with local labels. No incidence ledger, elementary phase theorem, clean-matching theorem, or branch fiber identity is reconstructed.
