# Independent review: C859–C870

**PASS — no numerical correction or material overclaim found.** The companion `INDEPENDENT_C859_C870.json` records28 passing checks, source identities and the12 journal-record hashes reviewed.

The review independently parsed the raw frozen File43 and File51a tables, recalculated each construction and compared the resulting fields with root artifacts. It did not accept the preparation packet's normalized values as independent evidence or merely replay the numbered scripts. Four NT-packet source snapshots match their hashes; File18's admitted Cainan row was also inspected directly. All artifact hashes recorded by C859–C870 match.

| Construction | Independent coverage | Result |
|---|---:|---|
| Complete display |78 rows,156 opening/closing values |All match literal source and civil generator |
| Name/interval/carrier distinctions |Luke76/75; Matthew41/40/41 |Source roles retained |
| Native Luke–MT field |22 nodes and21 local edges |All match literal source and suffix reconstruction |
| Restored Cainan |23 nodes and22 local edges |MT35\|130, NT70\|70 confirmed |
| Actual/Rounded response |22 residual comparisons |Complete negative-residual identity |
| Finite Key returns |77 indices per operator |E:0,23,46,69; P:0,69 |
| Second rail |Six returns; covariance of79 boundaries |Every radius preserved |
| Common49/70 subdivision |Full grid intersection |12 boundaries,11 blocks of490 |
| Primary reflection |78 boundary pairs |Complete closure; marked BJ pair verified |

The restored MT Cainan chain is Arphaxad2586 → Cainan2551 → Shelah2421 in the strict Rounded frame. Its local35|130 order is correct. The source File18 comparison row explicitly supplies Cainan2551 with Shelah2421; it remains distinct from the source table's Noah/Shem+2 conventions. No upstream Gear transport is performed.

File43's schematic display status is explicit in C859 and preserved thereafter. Neither the exact row reconstruction nor the Key returns establishes historical begetting ages. C866–C867 appropriately classify the complete return support without claiming independent numerical hits or statistical significance. C870 appropriately distinguishes automatic reflection closure from the source placement of BJ Creation and Conquest. No second inversion is executed in this reviewed block.

Three small provenance or presentation points should remain explicit in the final synthesis:

1. C869's check named `literal_field` compares against a **derived preparation field**, not a literal12-row source table. Its finding already calls the extended49-grid a comparison construction. This review independently recomputed the entire intersection and verified the literal source1470|2450|1470 partition, so the mathematical conclusion passes.
2. C868's generated36BC row carries the display label Jesus as the specified second rail. It must not be described as a revised Nativity date;6BC remains the birth hinge.
3. C864's restored MT coordinates retain File51a's strict no-Shem+2 state. Their agreement with an admitted Cainan row does not promote the entire generated comparison into a new canonical table.

These are scope reminders, not requested numerical repairs. No canonical source or numbered root action was changed by this review.
