Integrated reader review

Reviewed: c1433_c1482/deliverables/490d_Chronological_Families_Explanation_C1431.md, including the introduction, “How the three inverse families connect internally,” and conclusion.

Result: no necessary mathematical, source-role or novelty correction found. The new findings are integrated into the larger explanation without excessive boundary discussion.

• The six partition-response rows agree with their fixed source intervals. The formulas for moving the division, d_L−d_U, and retaining both nodes, −d_U, are correct. The 990 place-value explanation has its stated decimal register.
• MT Regular refinements and MT Cumulative Flood+Shem →13016 are correctly marked inherited. The systematic LXX/SP comparison and separate MT Shem-only partition are presented as the extension.
• The SP upper-branch claim is correctly restricted to the selected Flood/Shem/Fall nodes. Their Conquest-held shifts are all −1980; their Nativity-stage shifts relative to the original coordinates are all +720. The held terminal is explicitly outside this translated branch.
• The 3336 incidence is confirmed in the recovered frozen Moses_LXX_native_complete_path.json, SHA256 349e15040eb75bcb325bb2c83865a847266e0b60a265da53410dc040515fd403. It explicitly lists Rounded Noah 3836, Shem 3336 and Arphaxad 3236, in the native-Cainan source state omitting Shem +2. The reader gives 3336 its proper LXX Regular role and keeps the SP generated role separate.
• The 5436 incidence preserves its MT Rounded Cumulative Shem identity and SP inverse-Flood identity. The 610 head-gap preservation is not overstated as a whole-path translation.
• Accepted SP Fall heads remain 4406/13396, with lower Flood nodes unchanged. No discarded SP alternative is reintroduced as a final solution.
• C1432's 1866 pivot is correctly the MT Minimum Covenant; the LXX source trunk retains its full-430 native-Cainan frame. The reciprocal is a Key inverse, not a second decimal reversal. The head-only scope and separate upper-branch map are clear.
• The circuit through 13306, 11606, 14306 and 14116 is arithmetically correct and expressly shares source inputs. It is not claimed as independent evidence or a universal chronological map.

The introduction and conclusion accurately emphasize the new internal relationships while retaining the inherited source-generation explanation. No optional expansion is recommended for this review.
