In a compact choice of basis, only one adds a new nonzero numerical span: **460**. The other six specify interval correspondence, paired reflection and the supplied partition ratios. Those endpoint assignments and ratios remain inputs; the reduction does not establish them from the number 460 alone.\n\nThe resulting **1058, 190, 5819 and 5+5 equality are dependent consequences**. A further source-qualified consequence is\n\n\\[\n\\boxed{20=3+17=10+10\\quad\\text{in units of }529.}\n\\]\n\nAcross the five supplied 3+7 chains, the Christ-period landing is the midpoint of a **mixed cumulative 20×529 Mirror interval**. This remains valid for the principal 6 BC landing without requiring the unsupported 2651n regular Flood midpoint. It is another endpoint realization of the 20-fold width, not an independent calibration of that width.\n\n**What is held.** The principal reconstruction is C06's N02 packet, with its explicitly retained apparent-Creation comparison. Regular Gears remain confined to Noah/Shem/Flood. Creation stays Normal/G2; its ordinary and apparent fields remain distinguished. SP's person companion is confined to Noah/Shem, while Flood close remains an independent event boundary. The main regular profile is full-430/Terah-0/MT-SP-Cainan-OFF; the alternate MT Flood midpoint retains its separate full-430/Cainan-ON/Terah+60 profile. Native LXX Cainan ON and derived OFF remain explicitly identified.\n\nAll coordinates below are **signed paired centers**, with the fixed Mirror axis at January AD1. A BC coordinate C is −C, displayed as (C+1)t/Cn BC; its paired reflection has center +C, displayed as AD Ct/(C+1)n. There is no civil year zero.\n\n**The retained C06 variables and equations.**\n\n| Symbol | Signed center | Source role |\n|---|---:|---|\n| a | −4444 | Apparent SP Creation closing |\n| o | −4421 | Ordinary SP Creation opening |\n| b | −4419 | Ordinary SP Creation offset 2 |\n| f | 2456 | Reflected MT G1 Flood start |\n| g | 2458 | Reflected MT G2 Flood start |\n| m | 2757 | Reflected SP G2 companion Noah death |\n| n | 3056 | Reflected MT G1 Noah birth |\n| h | 3108 | Reflected SP G2 Flood start |\n| s | 3706 | Reflected SP G1 primary Noah birth |\n| c | −5287 | Cumulative LXX OFF later member |\n| c₋ | −5885 | Cumulative LXX OFF earlier member |\n\nThe original ten relations are retained as written:\n\n| ID | Equation |\n|---|---|\n| R01 | o−a=23 |\n| R02 | b−o=2 |\n| R03 | g−f=2 |\n| R04 | n−f=600 |\n| R05 | 25f−23n−2a=0 |\n| R06 | 25n−23s−2b=0 |\n| R07 | h−g=s−n |\n| R08 | 2m=g+n |\n| R09 | b−c=868 |\n| R10 | c−c₋=n−g |\n\nR05 and R06 retain their source-qualified anchored dilation meanings from C05–C06. The measured **868 attachment remains an input**. These relations give L=n−g=598, s−n=650, g−b=6877 and s−c=8993; C12 does not rerun the earlier search that identified their endpoints.\n\n**Seven added endpoints require seven added relations.**\n\n| Symbol | Signed center | Source role |\n|---|---:|---|\n| u | −6345 | Cumulative LXX native-ON earlier member |\n| q | 1400 | Reflected Conquest member, AD1400t/1401n |\n| v | 2648 | Reflected MT G2 Flood, retained ON/+60 profile |\n| A | −5293 | C10 cumulative MT ON Flood member |\n| X | −3706 | Actual BC SP G1 primary Noah birth |\n| Y | −2648 | Actual BC MT ON/+60 Flood midpoint |\n| Z | −3 | C10 Christ-period landing, 4t/3n BC |\n\nWrite **E=c−u**. The compact extension is:\n\n| ID | Equation | What the relation supplies |\n|---|---|---|\n| R11 | c₋−u=460 | Cumulative Cainan insertion |\n| R12 | s−v=E | The retained cumulative/regular equal-interval correspondence |\n| R13 | g−q=E | The Conquest/Flood correspondence |\n| R14 | X+s=0 | Paired reflection of SP Noah |\n| R15 | Y+v=0 | Paired reflection of alternate MT Flood |\n| R16 | 2(X−A)=3E | The supplied 3-fold first leg, measured against the 2-fold interval |\n| R17 | Z−A=5E | The supplied 10-fold outer interval, measured against the 2-fold interval |\n\nR12 and R13 are statements about the **identified endpoints**, not permission to assign a source label to any point produced by the equations. R16 and R17 retain the dimensionless allocation choices **3/2 and 5** from the supplied construction. In particular, the presence of just one new nonzero right-hand-side constant does not reduce the seven source and incidence choices to one historical assumption.\n\nThe checker uses the expanded forms, for example R12 as v−s−u+c=0 and R16 as 2X−2A−3c+3u=0. It solves the complete system exactly over rational numbers.\n\n**The square-of-23 unit is recovered from the retained spans.**\n\n\\[\nL=600-2=598,\n\\qquad E=L+460=1058,\n\\qquad\\boxed{K=E/2=529=23^2.}\n\\]\n\nNo separate 529-length datum is added to this basis. The commensuration\n\n\\[\n10\\times598=13\\times460=5980\n\\]\n\nconnects C06's 13-fold Creation width to E. It follows that\n\n\\[\ng-b=13K,\\quad g-q=2K,\\quad\\boxed{q-b=11K=5819}.\n\\]\n\nThe Conquest **attachment** R13 is an independent endpoint relation; once it is retained, the numerical 5819 does not require another calibration. Its membership in the Conquest field is verified separately in C09–C11 and preserved here.\n\nLikewise,\n\n\\[\nv-g=(s-g)-E=(650+598)-(598+460)=\\boxed{190}.\n\\]\n\nFile_18 and the retained profile independently identify this as **130+60**. The number 190 follows in the compact reconstruction, but the regular Cainan and Terah operations do not become the cumulative 460 insertion.\n\nThere is an equivalent source-first basis: replace R12 by the directly documented **v−g=190**. The two sets have identical affine row spaces. This makes the distinction precise: one may use the regular profile displacement or the equal-interval correspondence as the reconstruction relation; neither constitutes extra independent evidence once the other relations are held.\n\n**The retained 5+5 equality adds no further constraint.** Reflection and R12 give\n\n\\[\nY-X=E=2K.\n\\]\n\nTogether with R16–R17 this yields\n\n\\[\nX-A=3K,\\quad Y-X=2K,\\quad Z-Y=5K,\n\\]\n\\[\n\\boxed{Y-A=Z-Y=5K,\\qquad Z-X=7K.}\n\\]\n\nThe midpoint equation **A+Z−2Y=0** has the exact certificate\n\n\\[\n\\boxed{2R12+2R14-2R15-R16+R17.}\n\\]\n\nHere each R denotes its zero-form linear equation. Thus the old 5+5 observation is compatible with, and algebraically implied by, the retained equal interval, reflection and 3+7 allocation. The source qualification of Y is still a separate requirement; this implication does not supply a 2651n Flood event in the principal opening row.\n\n**The independence claim is narrow and reproducible.**\n\n| Exact linear-algebra result | Value |\n|---|---:|\n| Named endpoint variables | 18 |\n| Rank of the seventeen relations | 17 |\n| Rank after deleting any one relation | 16 |\n| Rank after adding a=−4444 | 18 |\n| Rank after appending all 21 derived relations | 17 |\n\nWithout the final source anchor, the remaining free direction moves the original eleven points and u/q/v by +δ, while A/X/Y/Z move by −δ. This is the reflection behavior already found in C11. It is not a common translation of all eighteen coordinates and is not claimed as a source-preserving chronological action.\n\nFor every new relation the packet supplies a formal deletion witness. For example, deleting R13 permits q to move while the entire 3+2+5 partition stays fixed. Deleting R16 permits A and Z to move together while leaving the Conquest comparison and the 10-fold outer length fixed. These demonstrate the independent endpoint-placement constraints; the perturbed values are not admitted chronologies.\n\nDeleting R11 exposes the remaining numerical calibration: with the old anchored core held and u increased by λ, q and v increase by λ, Y decreases by λ, A increases by 3λ/2 and Z decreases by 7λ/2. The supplied 460 insertion fixes that freedom. Once the stipulated correspondences and ratios are held, an equivalent numerical calibration could use the regular 190 offset or the Conquest 11-fold relation; their source meanings remain distinct.\n\nThis rank calculation reconstructs one selected packet. It does not reduce the original three-coordinate configuration space to one dimension, count independent textual witnesses, or prove a minimal axiom system for the whole repository.\n\n**The 20-fold interval has a sourced Christ-period midpoint.** This consequence has a particularly simple proof in positive BC Nisan coordinates. Let N be one of the supplied Noah births, A its cumulative MT ON predecessor, Z its Christ-period landing, and D the admitted cumulative LXX OFF member in the 8993 comparison. Then\n\n\\[\nA-N=3K,\\qquad N-Z=7K,\\qquad N+D=17K.\n\\]\n\nReflect the cumulative D boundary to its AD paired position. The source path through actual BC Noah gives\n\n\\[\n\\boxed{A\\text{ BC}\\ \\longrightarrow\\ N\\text{ BC}\\ \\longrightarrow\\ D\\text{ reflected}\n\\quad=3K+17K=20K.}\n\\]\n\nThe path through the landing gives\n\n\\[\nA-Z=10K,\\qquad Z+D=17K-7K=10K.\n\\]\n\nTherefore **Z is the midpoint of the same 20K interval**. This also gives the common refinement **3+7+10**, without requiring an intermediate regular Flood node.\n\n| MT cumulative ON A, Nisan BC | SP Noah N, Nisan BC | Landing Z, Nisan BC | Reflected LXX cumulative OFF D | Two equal halves |\n|---:|---:|---:|---|---|\n| **5296** | **3709**, G3 companion | **6** | AD5284t/5285n | 5290+5290 |\n| 5295 | 3708, G2 primary | 5 | AD5285t/5286n | 5290+5290 |\n| 5294 | 3707, G2 companion | 4 | AD5286t/5287n | 5290+5290 |\n| **5293** | **3706**, G1 primary | **3** | AD5287t/5288n | 5290+5290 |\n| 5292 | 3705, G1 companion | 2 | AD5288t/5289n | 5290+5290 |\n\nAll five cumulative endpoints were checked against the held source fields. The principal paired chain is\n\n\\[\n\\boxed{5297t/5296n\\text{ BC}\n\\ \\xrightarrow{5290}\\ 7t/6n\\text{ BC}\n\\ \\xrightarrow{5290}\\ \\text{AD }5284t/5285n.}\n\\]\n\nFor its second half, the civil component checks are **7+5284−1=6+5285−1=5290**. Its full width is **5297+5284−1=5296+5285−1=10580**. Thus the no-year-zero and paired-season conventions agree.\n\nThis is a **mixed MT-ON / LXX-OFF cumulative comparison**, distinct from the previously retained 5290-opening self-Mirror construction of the same width. The interval's midpoint is the selected Christ-period landing, while the fixed reflection axis remains January AD1. The five rows retain the supplied landing field; they are not five independent historical nativity claims.\n\nThe extension does not add a new 20-fold calibration: **20=17+3** and **10=17−7** supply both halves. In the N02 linear register these appear as **A+c=−10580**, **Z+c=−5290**, and **A−c=2Z**. Their certificates retain the old R09 **868 attachment**; that attachment has not been derived from the 598/460 core. The principal row's 2651n midpoint failure is unaffected, because the new 20-fold path uses the Noah and Christ-period nodes directly.\n\n**Source limits remain active.** The eighteen-node packet is fully sourced at the principal N02 attachment. C11's N04 core follows the corresponding +2/−2 displacement, but translating the entire C06 apparent packet would require **4442 BC**, outside the held apparent Creation field. N01/N03 keep their valid partial Conquest/Flood-close paths; their full Creation expansions still require unsupported MT Noah births **3055/3057**. No missing Shem join is supplied. The proposed full-week 300→299 compression and its extra 4413 boundary remain conditional and are not used in this basis.\n\nThe five mixed cumulative 20-fold comparisons were checked separately against the actual fields, so their support does not depend on extending the full eighteen-node packet to every row. The previously recorded seasonal-envelope interpretation and the author's confirmation of the 5292 typo correction remain unresolved.\n\n**Evidence and checkpoint.** `evidence/check_c12.py` passes **156 exact checks**. `C12_BASIS_CERTIFICATE.json` contains the endpoint register, seventeen equations, oriented free direction, twenty-one exact affine consequence certificates and seven deletion witnesses. `C12_RESULTS.json` contains source checks, ranks, the alternative-basis equivalence, all five mixed cumulative paths and the retained exclusions. Ten frozen inputs include File_18/File_09 and the relevant C06/C10/C11 reports and evidence. Both generated result files reproduce byte for byte in an isolated replay; input and artifact SHA256 manifests accompany the packet.\n\nNo canonical source or historical graph was changed, and no completed campaign was rerun. The completed continuation is now **C01–C12**, alongside the recovered original **Reports 01–10**. Interrupted original **Reports 11–25** remain unestablished as completed; C12 is a new continuation supplement.\n\n**Best next bounded step:** leave the **868 attachment and 460 insertion symbolic** in this reduced system, then distinguish identities that survive from 529-family alignments that require their exact calibrations. Use the retained equations and source limits without rerunning the older endpoint campaigns. **High is sufficient.**\n", "evidenceLinks": [{"id": "d-68301ab760bfbe2e", "title": "File 18"}, {"id": "d-45851004c5864229", "title": "File 09"}]}
