### Actual and Rounded chronology retain their selected states

The Actual and Rounded families can be compared precisely when each date retains its source role. For the present Creation bridge, the selected Actual completion endpoints are 14004 BC in cumulative chronology and 4114 BC in regular chronology. Their Rounded companions are 14006 and 4106 BC. The respective gaps are therefore 9890 and 9900 years. These figures describe two related, explicitly selected comparisons.

The changes have different causes. In the regular calculation, six years arise from the combined row-rounding residuals; the standard-versus-strict Shem convention supplies two further years. Together they explain the movement from Rounded 4106 to selected Actual 4114. In the cumulative calculation, row rounding preserves the 12600-year total and its 14006 BC head. Selecting the lower Actual completion endpoint supplies the separate two-year change to 14004.

This distinction makes the shared structure more informative. The displacement pair, cumulative −2 and regular +8, preserves the weighted coordinate (4C+R)/5 because 4(−2)+8=0. Here C and R denote cumulative and regular Creation respectively. Both selected pairs therefore yield 12026 BC. That conservation belongs to these stated endpoints and conventions. The source rows, endpoint selections, and individual chronological roles remain part of the explanation.
