### The source rows explain the three cumulative Flood connections

The MT–LXX **910-year** displacement now has an explicit source explanation. In the rounded post-Flood lifespan rows it is

\[
910=460+(25+25+40+100+100+100+60)=460+450.
\]

The 460 is second Cainan; the remaining terms belong to Arphaxad, Shelah, Eber, Peleg, Reu, Serug and Nahor. Terah contributes zero. Equal Shem and Noah lives preserve this difference through their cumulative boundaries. LXX Lamech's rounded 755 versus MT 775 then reduces it to **890 = 460 + 430** from Lamech back to Creation. Thus the familiar 430 belongs to that later comparison; the Flood difference uses 450. Rounding preserves the Creation difference because the Actual calculation gives the same \(914-24=910-20=890\). [File18 §§2.2,4.2,6D; File51a §16; C1586–C1589]

SP's post-Flood source difference is **120**, from Eber and official Terah each contributing 60 fewer lifespan years. Reversal changes its lower leg from 3310 to 1330, contracting it by 1980. The MT–SP inverse Flood separation therefore becomes **120 + 1980 = 2100**. This is generated before selecting a restoration target. [File18 §3.2.1; C1590–C1592]

| MSS | Original lower leg | Inverse lower leg | Completed inverse Flood, BC | Span to 536 BC |
|---|---:|---:|---:|---:|
| MT | 3430 | 3430 | 7536 | **7000** |
| LXX | 4340 | 4340 | 8446 | **7910** |
| SP | 3310 | 1330 | 5436 | **4900** |

All three lower inverse legs are multiples of 70: **49, 62 and 19 units**. Completing the Nativity stage and measuring to restoration adds the same amount to each:

\[
2700+(1406-536)=3570=51\times70.
\]

Their restoration spans are consequently **100, 113 and 70 units of 70**. The LXX 7910 is the third member of this fixed comparison. Moving its target from restoration 536 to Exodus 1446 removes the same source-derived 910 and gives **8446−1446 = 7000**, matching MT 7536−536. Its unsimplified 7910 also equals the LXX Regular inverse Flood–Nativity interval, 7916−6: the two start points and two targets differ by the same 530. [C1595–C1599]

### One 7000-year packet connects MT, LXX and SP

The 910 transport preserves a complete ordered packet, including both internal nodes:

| Node in the comparison | MT-based packet, BC | LXX packet, BC |
|---|---:|---:|
| Completed inverse cumulative Flood | 7536 | 8446 |
| Ordinary cumulative Shem | 5436 | 6346 |
| Ordinary / held-inverse cumulative Flood | 4836 | 5746 |
| Appointed target | 536, restoration | 1446, Exodus |

Every corresponding node differs by 910, and both packets have the same partition:

\[
7000=2100+600+4300,\qquad4900=600+4300.
\]

SP enters at the MT packet's Shem coordinate: **5436 is also the completed SP inverse cumulative Flood**. The source condition for that junction is \(2700-(120+1980)=600\). The common stage displacement, the SP source/reversal difference and Shem's lifespan therefore explain why the two constructions meet. [C1592, C1600–C1603]

This transport belongs to the specified packet. The primary inverse cumulative Creation heads have different upper inverse legs, 7190 in MT and 5190 in LXX, so their whole-head difference is \(910-2000=-1090\). Likewise, keeping the Flood and Shem cuts preserves the lower 910 transport, whereas reversing Conquest–Shem as one leg produces a 1900 difference. The named cuts remain part of the explanation. [C1593–C1594, C1604]

### Shem's 600 years join restoration to the Jubilee endpoint

A second whole-interval translation joins the Babylonian comparison directly to the SP Jubilee chain. MT cumulative Shem **5436 BC → Flood 4836 BC** is 600 years, and **536 BC → AD 65** is also 600 civil years:

\[
536+65-1=600.
\]

Both endpoints of the 4900-year interval therefore move forward together:

| Placement | Start | End | Years |
|---|---:|---:|---:|
| LXX Shem | 6346 BC | 1446 BC | **4900** |
| MT Shem / SP inverse Flood | 5436 BC | 536 BC | **4900** |
| MT Flood | 4836 BC | AD 65 | **4900** |

The successive forward translations are **910 and 600 years**. The final row is exactly the last **10 Jubilees** of the SP **13 + 10** division. Thus the restoration interval reaches the AD 65 interval through Shem's named lifespan, while SP supplies an inverse Flood at the shared 5436 junction. All three rows use ordinary same-side or civil elapsed counting. The separate Rounded AD 2166 transport below retains its own convention. [C1617–C1619]

The SP 9800 and 11270 comparisons also have one source calculation: \(4100+7100=11200=8\times1400\). Subtracting one 1400 gives 9800 to Conquest; adding the civil 70 from 6 BC to AD 65 gives 11270. Their two Jubilee counts are linked because Conquest→AD 65 is already **3×490**. The LXX self-retained Flood at 5746 supplies a finer cut in the existing SP–MT chain:

\[
11206\to5746\to4836\to1406\text{ BC}\to\text{AD }65,
\]
\[
(78+13+49+21)\times70=161\times70=23\times490.
\]

The first two pieces recombine into 13 Jubilees. The fixed comparison of all six primary spines retains the other values: among completed Flood nodes, SP Regular alone meets both selected Jubilee targets exactly. [C1612–C1616]

### One ordered path contains the new large spans

Keeping the MT inverse Flood inside the established LXX–SP comparison gives

\[
13136\longrightarrow7536\longrightarrow5436\longrightarrow536\text{ BC},
\]
\[
12600=5600+2100+4900=(8+3+7)\times700.
\]

The LXX Regular inverse head, MT inverse cumulative Flood and SP inverse cumulative Flood each contribute a named node. Keeping the MT cut gives **5600 + 7000**; keeping the SP cut gives the inherited **7700 + 4900**. Both are coarser partitions of this same path. Its first two edges follow directly from the inverse source words: \(5600=9030-3430\) and \(2100=3430-1330\). [C1605–C1609]

The existing Minimum Covenant point **1866 BC** can also remain between 5436 and 536. The resulting partition is

\[
12600=5600+2100+3570+1330.
\]

Its first three components total **11270 = 23×490**, the established LXX-head→Covenant radius; its final three total **7000**, and its final two **4900**. This joins the Flood, Babylonian and Covenant comparisons in one ordered structure. The repeated displays share these source nodes and are not independent confirmations. [C1625]
