bj='''## Jubilees extends the same path model

Jubilees adds index contraction, weighted duration contraction, and alternative subdivisions of retained paths. Its 22-head/work parallel is a structural interpretation in File53. Inserting Kainan at position 13 gives a 23-head list while preserving every surviving name’s order. The index change is one position; the associated chronological weight remains source-specific.

| Representation of the removed element | Weight | What it measures |
|---|---:|---|
| Head index | 1 | Position |
| BJ secondary birth reconstruction | 57 | Years |
| File18 regular Cainan | 130 | Begetting interval |
| File18 cumulative Cainan | 460 | Lifespan contribution |

No BJ Kainan lifespan is supplied here, so the table does not infer a BJ cumulative 460. The supplied secondary deletion path changes Creation3856 → Flood2549 → Kainan2482 → Shelah2425 into3799 → 2492 → 2425. It preserves the inherited Creation–Flood1307 and contracts the total1431 to1374. The controlling SP-to-BJ7+1300 construction remains inherited input, not independent corroboration.

The displayed2450-to2400 reduction combines two operations. Creation3856 → Conquest1406 and Fall3849 → rest1399 each span2450. Removing57 from Creation gives3799, whose span to rest is2400. The reduction50 is therefore57−7, with the starting role changed. File53’s positive four-node reflection about2599 uses original Noah/Shem/Flood comparison nodes3149,2649,2549,2049 against compressed Creation3799 and rest1399. It is a separately declared comparison object; the expunged ledger’s Flood2492 does not replace2549 in that reflection.

The complete post-Abraham paths supply an even clearer whole-family example:

| Ordered interval | Biological reconstruction | Surface ledger | Surface minus reconstruction |
|---|---:|---:|---:|
| Abraham → Isaac | 100 | 111 | +11 |
| Isaac → Jacob | 60 | 59 | −1 |
| Jacob → Egypt entry | 130 | 125 | −5 |
| Egypt entry → Conquest | 285 | 280 | −5 |
| Whole Abraham → Conquest | **575** | **575** | **0** |

The boundary residuals are0,11,10,5,0 AM years. Adjacent differences generate the four changes above, using the same difference/accumulation rule as the mode and rounding fields. The six supplied jubilee timestamps regenerate exactly from AM=49(j−1)+7(w−1)+y. That validates their arithmetic encoding; it does not explain historically why those particular timestamps were selected. The source prose’s Isaac–Jacob70 conflicts with the literal59, and the surface Jacob lifespan142 conflicts with the stated147. Both tensions remain. The generated reconstructed death2183AM and literal surface death2188AM still preserve the final17 years after their respective Egypt entries.

Two partitions of the biological290-year subpath also fit one refinement. The six supplied nodes1981,1881,1866,1821,1806,1691BC have gaps100|15|45|15|115. Selecting biological birth cuts gives100|60|130; selecting sacrifice and death gives115|60|115. The six nodes, including four internal boundaries, retain distinct roles.

The larger bookend path3856 → 3396 → 1906 → 1446 → 1406 has gaps460|1490|460|40. Expanding only the call-to-Exodus460 by25/23 gives500 and reaches Conquest1406 while retaining the earlier1950. The source NT heads5326 and2876 share the2450 duration as35×70=50×49. That is a duration interface; it does not identify their events or transfer the BJ head list.
