The SP **Regular** original path from Nativity to Conquest to Flood is 6→1406→3106 BC, with legs 1400 and 1700. Reversing those original legs once gives\n\n\\[\n6+4100+7100=\\boxed{11206\\text{ BC}}.\n\\]\n\nThis is the inverse Flood node inside the accepted SP Regular path to 14306. It lies **9800 = 20×490** years before Conquest. Conquest 1406 BC to AD 65 supplies another **1470 = 3×490**, using civil counting without a year zero. Thus\n\n\\[\n11206+65-1=11270=23\\times490.\n\\]\n\nThe MT Cumulative Flood at **4836 BC**, retained by its Conquest-held inverse construction, provides an additional named division:\n\n| Ordered endpoints | Years | Units of 490 |\n|---|---:|---:|\n| 11206 BC → 4836 BC | 6370 | 13 |\n| 4836 BC → 1406 BC | 3430 | 7 |\n| 1406 BC → AD 65 | 1470 | 3 |\n| Whole interval | **11270** | **23** |\n\nThe **13 + 7 + 3** chain joins SP Regular inversion, MT Cumulative inversion, Conquest and AD 65. Grouping its first two legs gives the user's **20 + 3** division; grouping its final two gives **13 + 10**. Its whole 11270 interval also translates the earlier MT Creation→SP inverse cumulative Flood pair **14006→2736 BC** forward by exactly **2800 years at both endpoints**, reaching **11206 BC→AD 65**. The same interval therefore has both same-side and cross-axis placements, with the civil conversion explicit. [Comparative study §§3.2,7.2; Style Guide civil-span rule; C1583]\n\nThe second observation uses the **MT Cumulative** path. Its original Flood–Conquest leg is \\(4836-1406=3430\\), which is self-reversing. With Conquest held, the inverse Flood stays at 4836. The Nativity extension then gives\n\n\\[\n6+4100+3430=7536=4836+2700,\n\\qquad7536-536=\\boxed{7000}.\n\\]\n\nThis extends the Babylonian comparison through the two completed inverse cumulative Flood nodes:\n\n\\[\n7536\\longrightarrow5436\\longrightarrow536,\n\\qquad7000=2100+4900.\n\\]\n\nHere 7536 is the MT inverse cumulative Flood; 5436 is the SP inverse cumulative Flood, already coincident with ordinary Rounded MT Cumulative Shem. Their **2100-year separation** follows from their reversed lower legs, \\(3430-1330=2100\\), and survives the shared Nativity extension. From restoration, the two Flood nodes stand **100 and 70 units of 70** earlier. This places the new 7000 within the existing 4900 comparison through one named intermediate node. [C1583]\n\n\n## Verification and provenance\n\nAll 27 exact checks passed. The verifier uses integer division and remainders for reversal of original duration segments, and the civil coordinate conversion BC B → 1−B / AD A → A. Independent arithmetic review agreed with both supplied links, the 13|7|3 partition and the 2800-year translation. No second decimal reversal was used.\n\nThe source nodes 11206 and 7536 are already in the supplied comparative study (§§7.2 and 3.2). The new contribution is their joined target intervals and common named partitions. The source excerpt preserves the Style Guide’s no-year-zero rule. The current families explanation was updated from version 3; the completed C1483–C1582 research packet remains unchanged.\n\nThe accompanying evidence packet contains `C1583.json`, its C1582 predecessor, controlling excerpts/source, `verify_flood_links.py`, results and the updated reader. Run `python3 verify_flood_links.py` to replay this bounded arithmetic.\n\n**Reassessment:** These intermediate-node connections strengthen the family explanation. Continue the planned source-based synthesis of the MT–LXX cumulative 910 translation using existing row reconstructions; do not replace it with an unconstrained search for new endpoint matches.\n\nC1582 predecessor SHA256: `b7addc59554061e63897a05b62c4aa61bb1479c6be540d4ebb1714b3c626debe`  \nC1583 record SHA256: `aa1b7721d35e8629ef794233dd5b0ddf8d4e8772d75d799357d098b0e97c933e`\n"}
