C711: eighty-step checkpoint

The4346 hinge now has two explicit anchored MT constructions. Their190 source-state difference balances the232−42 gain difference; their completed radii differ by the40-year anchor separation. The supplied1470 ladder and4900 Danielic path can then be read as refinements around that hinge. The admitted directional690 comparison matrix likewise follows from a single50=(E−P)690 balance. These fixed source comparisons retain their inherited status.

A separate, amendment-local twelve-node phase field tests whole-set closure:5842 maps all12nodes to their mirror, while the other supplied totals produce8/8/4overlaps. Its conditional placement theorem follows from the center equation c+L=−c. This is affine reflection in its own phase chart, not File52c decimal reversal. Remote source extensions remain unopened.

The larger explanation is now organized by source realization, retained subdivision, translation/reflection, phase-aware placement and calendar calibration. Exact conserved quantities explain why some changes preserve family structure.

C703 records wording corrections to the preceding checkpoint: the residual interpretation is2.5 additional336-day units=840days; native14006 is distinguished from generated14146/14846; the retained macro table belongs to Supplement A§10.3.

Next: integrate the results into a readable account and exact diagram, independently review them, and preserve the complete100-step record.
