Independent source and editorial review — C1585–C1634

Reviewed the new reader sections and the expanded C1584 forward-path paragraph. This is a bounded review of the final synthesis, not a new research branch. No reader, source, or journal file was edited.

Result: no blocking numerical or source-state defect. Twenty-one independent checks pass. The new relations retain ordinary, Conquest-held inverse, and completed inverse roles correctly in the tables. The native Cainan-ON/full-430 LXX and accepted SP Fall controls remain explicit in the report's controlling comparative introduction. None of these additions changes the inputs.

Small actionable wording fixes

1. In “One 7000-year packet…”, change “The primary cumulative Creation heads…” to “The primary inverse cumulative Creation heads…”. The stated −1090 is the difference of the reconstructed inverse heads (13636−14726 or 10936−12026). Ordinary cumulative source heads differ by +890. The surrounding reference to inverse legs makes the intended meaning recoverable, but the missing adjective is avoidable ambiguity immediately after the +890 source explanation.
2. In the first new table, change “Completed Flood BC” to “Completed inverse Flood, BC”. All three rows are cumulative; either introduce the table explicitly as cumulative or use “Completed inverse cumulative Flood, BC” if layout permits. This is a label clarification; its entries 7536/8446/5436 are correct.
3. In the source paragraph, “then reduces it to 890 = 460 + 430 at Creation” can be made more informative as “then reduces it to 890 = 460 + 430 from Lamech back to Creation.” This states the exact boundary of the plateau rather than only its ultimate endpoint. Arithmetic and existing source references already support it.
4. In the concluding synthesis, repair “a600-year Shem translation” to “a 600-year Shem translation.”

No additional caveat or deeper mirror discussion is needed. The remaining prose is sufficiently clear for the stated scope.

Source findings confirmed

• File18 §§2.2, 4.2 supplies MT/LXX lifespans; File51a §16.1 independently rounds whole lives. Flood 910 is Cainan 460 + the other post-Flood 450. Terah contributes zero; the 450 is 25+25+40+100+100+100+60.
• Identical cumulative Shem 600 and Noah 950 preserve the source 910 plateau. Lamech 755−775=−20 changes it to 890. The actual chain uses 914−24=890, as File18 §6D states via its Cainan-leveled 454−24=430 calculation. Thus no regular +60 Terah or Sojourn adjustment has entered the cumulative row sum.
• File18 §3.2.1 and §6C support SP Eber −60 and official Terah −60. The source 120 and inverse 1980 together give 2100. The accepted Fall 5 remains confined to the upper SP source endpoint and does not move the Flood lower leg.
• “Ordinary cumulative Shem” is correct for 5436/6346; those are not their completed inverse Shem nodes. “Ordinary / held-inverse cumulative Flood” correctly distinguishes 4836/5746 from completed 7536/8446. SP 5436 is the completed inverse cumulative Flood and shares MT ordinary cumulative Shem's coordinate only.
• The 7000 packet is the full translated four-node sequence 7536/5436/4836/536 →8446/6346/5746/1446, with +910 at every node. The target displacement has the same numerical magnitude as the source-row displacement; the report does not need to assert that source rows historically generated the Exodus–restoration dating.
• The 600-year forward civil translation is exact: 5436→4836 and 536 BC→AD 65 both span 600, taking 4900→4900. It joins the last 10 Jubilees of the earlier SP 13+10 partition without changing the counting convention.
• The finer 11206→5746→4836→1406 BC→AD 65 chain gives 78+13+49+21 units70. Its first two portions are 91×70=13×490; its final two are 70×70=10×490.

C1584 forward path and deferred-mirror scope

Freshly checked File52c_latest §§1.4 and the protocol register: q(B BC)=1−B; q(AD A)=A−1; Rounded width B+A−2; literal civil count is one greater. The expanded paragraph is exact:

13136→7536→5436→536 BC moves forward 2700 in q-space to 10436→4836→2736 BC→Rounded AD 2166. The edges remain 5600,2100,4900; the total remains 12600. The report explicitly preserves civil counting for AD 65. No reflection of the whole spine, new mirror axis, second decimal inversion, Gear transport, or new source state is introduced. Merely identifying Abram's reflected birth and transporting the established path stays inside the user's declared scope.
