Solution move 001 - Challenge and bounded target

SG8 asks whether flavor structure is actually produced by the shape. The bounded task solved here is narrower and testable: reconstruct the frozen one-angle CKM texture, compare its abs(Vtd) output with the declared 2024 measured anchor on one complete ruler, adjudicate the negative legacy branch, and classify the rebuilt measured-spurion EFT without confusing reconstruction with prediction. A polished narrative cannot upgrade the answer. The legacy texture can be permanently false while the conditional EFT identity remains usable and the geometric origin of flavor remains OPEN. This worked chain therefore treats scoped success and physical closure as different outputs.

The deliverable must show every numerical operation, the provenance firewall, the sealed six-session replay, the twenty-one harness controls, and all local closure interfaces. It ends only after the 39 inherited and local dependencies are propagated. The original evidence dossier is preserved byte-for-byte; this file is a replacement challenge solution with an independent operational sequence.

Solution move 002 - Permitted evidence and authority

The permitted inputs are the SG8 frozen legacy chain, the measured abs(Vtd) anchor, the complete flavor ruler tuple, the cumulative SG7-to-SG8 dependency ledger, the machine flavor certificate, and the deterministic execution records. Numerical values may be recomputed from those sources, but their provenance labels may not be edited. The one-angle texture was frozen before the 2024 comparison packet; the PDG value is a MEASURED-ANCHOR; and the rebuilt EFT obtains its spurions from measurement.

The authority boundary rules out three shortcuts. First, a measured Yukawa matrix cannot be renamed a geometric output. Second, an internal randomized reconstruction cannot be described as the absent independent reviewer trial. Third, a local claims shrink cannot be described as a global board cutover. These restrictions are part of the solution, because violating any one of them would manufacture closure rather than demonstrate it.

Solution move 003 - Required outputs

The answer must issue four simultaneous terminals. The frozen legacy one-angle texture is CLOSED-NEGATIVE. The low-energy EFT, when supplied with measured spurions, is PASS-CONDITIONAL and classified as MEASURED-ANCHOR-RECONSTRUCTION. The geometric origin of flavor is OPEN. The physical SG8 gate and the global board cutover are OPEN with 39 blocking dependencies. The package-local claims cutover is PASS, but it has no authority to erase upstream rows.

Two execution labels are equally important. The supplied six-session reconstructed gauntlet passes all twenty-one controls, whereas the reviewer-randomized gauntlet is NOT-EVALUATED. Nature selection is NOT-CLAIMED. Any final sentence that drops these qualifiers fails the challenge even if its arithmetic reproduces 15.927965908641152 exactly.

Solution move 004 - Same-ruler preparation

The comparison observable is the dimensionless rephasing-invariant magnitude abs(Vtd). The source chart is the standard three-angle one-phase CKM chart; the target chart is the PDG 2024 three-generation unitary global-fit chart. Projection means construct the full unitary matrix and then extract abs(Vtd). Below mW the CKM elements are treated as constant, so operator running is not reassigned to the magnitude. The observer map is the identity on the low-energy invariant.

The uncertainty contract uses the arithmetic mean of the reported plus and minus one-sigma errors for the challenge pull. Correlation scope is explicitly marginal diagnostic only, not a global p-value. With observable, normalization, charts, scheme, projection, energy domain, observer map, running statement, and uncertainty rule all present, the ruler is complete. Removing any field changes the candidate and triggers an early wrong-ruler failure.

Solution move 005 - Provenance and prediction firewall

Exact algebra does not determine the origin of its inputs. A matrix identity can be exact once measured Yukawa or spurion matrices are supplied, yet contain no derivation of those matrices from the thirteen-dimensional parent. SG8 therefore separates the identity layer from the origin layer. The first may receive PASS-CONDITIONAL; the second stays OPEN until normalized overlap integrals, target-blind texture selection, complete transport, and independent tests exist.

The firewall also preserves the negative historical result. Falsifying one target-independent legacy texture is genuine information, but it does not validate a replacement chosen after residuals were known. Xi_OGF and similar repairs remain construction-anchored. A new name or a reduced residual cannot reverse the order in which target knowledge entered the model.

Solution move 006 - First-failure and no-hidden-dial discipline

Every candidate is checked in a fixed order: object identity, ruler completeness, provenance chronology, prediction label, pull arithmetic, and scoped terminal. Evaluation stops at the earliest hard failure. This prevents a decoy with an attractive later number from surviving an earlier conceptual defect. The sealed answer key records the expected first-failure rule before the witness comparison.

No parameter, covariance choice, flavor Actor, threshold correction, or label may be introduced after seeing the target unless it is declared as a repair input. Target-aware fitting can be useful, but it is not a prediction. The solution will therefore accept the incumbent claims-shrunk reconstruction and a provenance-clean repair proposal for evaluation while rejecting wrong-ruler, relabeled-spurion, arithmetic-error, and disguised-target-aware decoys at their first violated rule.

Solution move 007 - Freeze the legacy branch

Read the branch identifier SG8-LEGACY-ONE-ANGLE-120-DEGREE before opening the measured comparison. The numerical inputs are Vus=0.22436, Vcb=0.0408, Vub=0.00378, and delta=120 degrees. The archived output is abs(Vtd)=0.011447034. This chronology makes the branch a falsifiable legacy prediction rather than a repair trained on the 2024 value. The operation does not bless the texture; it merely establishes a clean object to test. A different angle, input magnitude, or phase would be a new branch and could not be substituted during adjudication.

Solution move 008 - Extract s13

The standard chart defines s13 directly from Vub. Substitution gives s13=0.0037799999999999999. No approximation or fit is performed in this move. The only admissible output is the frozen magnitude converted into the sine coordinate used by the CKM parameterization. The calculation remains within the legacy branch; it says nothing about why that value occurs in nature. Keeping that distinction explicit prevents an observed input from being counted as a successful geometric prediction.

Solution move 009 - Compute c13

Unitarity of the trigonometric coordinate pair gives c13=sqrt(1-s13^2). With s13=0.0037799999999999999, the positive standard-chart root is c13=0.99999285577448005. The sign choice is fixed by the conventional angle range, not tuned to the target. Squaring the two values returns one within floating-point precision. This normalization matters because both Vus and Vcb contain the common c13 factor; omitting it would move the comparison onto a different chart.

Solution move 010 - Recover s12

The standard matrix entry obeys abs(Vus)=s12*c13. Division by the previously computed c13 gives s12=0.22436/0.99999285577448005=0.22436160288988907. This value is slightly larger than the raw Vus magnitude, as required because c13 is below one. The move is deterministic and uses no abs(Vtd) information. Its audit check is to multiply s12 by c13 and recover 0.22436 at the precision of the frozen input.

Solution move 011 - Recover s23

Likewise abs(Vcb)=s23*c13, so s23=0.0408/0.99999285577448005=0.040800291486483661. Multiplication by c13 returns 0.0408. This independent extraction keeps the 2-3 angle tied to the declared chart. A candidate that divides one anchor by c13 but not the other would no longer implement the archived chain, even if a rounded final magnitude appeared close.

Solution move 012 - Complete the cosine coordinates

Take the positive roots c12=sqrt(1-s12^2) and c23=sqrt(1-s23^2). The values are c12=0.97450596260293842 and c23=0.99916732143050901. Each sine-cosine pair separately satisfies its unit-circle identity. These checks establish a full internally coherent angle tuple before the complex phase is applied. There is still no reference to the measured abs(Vtd) anchor, so the legacy prediction remains frozen.

Solution move 013 - Construct the complex Vtd entry

In the standard CKM chart the relevant element is Vtd=s12s23-c12c23s13exp(i*delta). Insert delta=120 degrees, with cos(delta)=-1/2 and sin(delta)=sqrt(3)/2. The minus sign in front of the phase term is part of the matrix convention. This operation combines the previously derived coordinates into a complex amplitude; it does not yet compare a magnitude. Rephasing can alter the complex presentation, but the next magnitude is invariant under that freedom.

Solution move 014 - Resolve real and imaginary components

Direct complex evaluation gives Re(Vtd)=0.010994301424665318 and Im(Vtd)=-0.0031874630126460133. The negative imaginary part follows from subtracting the positive sine component of exp(i*120 degrees). Squaring and adding the components provides an independent route to the final invariant. Recording both components exposes sign mistakes that could be hidden if only the absolute value were printed. The phase convention ceases to matter only after the magnitude is formed.

Solution move 015 - Form the invariant magnitude

Apply abs(Vtd)=sqrt(Re(Vtd)^2+Im(Vtd)2). The result is 0.011447033863555408, namely 0.011447033863555408 at the controlling precision. This is the exact reproduced legacy output used by the gauntlet. It is dimensionless and already on the declared low-energy CKM-magnitude ruler. No error bar has yet been attached because this leg reconstructs the frozen texture rather than a covariance analysis of its inputs.

Solution move 016 - Match the archived printout

The historical page printed 0.011447034. Its absolute difference from the recomputation is 1.364445917362289151e-10. That approximately 1.36e-10 discrepancy is ordinary decimal rounding, not evidence of a new prediction or a conflict between implementations. Agreement at this level certifies faithful reconstruction of the archived chain. It also fixes the value that must be tested; replacing it by a refitted number would evade rather than solve the legacy challenge.

Solution move 017 - Freeze the measured anchor

The comparison packet supplies abs(Vtd)=0.00858 with plus 0.00019 and minus 0.00017 at one sigma from equation 12.27 of the 2024 CKM review. Its provenance is MEASURED-ANCHOR and its fit scope is the three-generation unitary global CKM fit. This value is not inserted into the legacy calculation. It enters only now, after the prediction is reproduced, so the comparison is prospective with respect to the frozen texture even though the execution is being performed today.

Solution move 018 - Apply the declared symmetrization

The challenge explicitly defines sigma_sym=(0.00019+0.00017)/2=0.00018. This arithmetic mean creates a single marginal diagnostic ruler for the requested pull. It does not reconstruct the global likelihood or account for correlations among all CKM inputs. That limitation travels with the reported sigma count. A reader may prefer asymmetric or correlated treatment, but must label it as a different statistic rather than silently replacing the frozen challenge rule.

Solution move 019 - Compute the residual

Subtract the measured central value from the legacy magnitude: 0.011447033863555408-0.00858=0.0028670338635554075. The residual is positive, so the texture overshoots the measured anchor. Its sign is important for the directional check and its magnitude is far larger than either quoted one-sigma side. No rounding to the archived nine-digit printout is needed; the recomputed precision is retained throughout the division.

Solution move 020 - Evaluate the symmetrized pull

Divide the residual 0.0028670338635554075 by 0.00018. The resulting marginal diagnostic is 15.927965908641152 sigma, conventionally summarized as approximately 15.9 sigma. The large value decisively rejects the exact frozen texture under the declared challenge rule. Because the denominator is a marginal fit uncertainty, this number must not be advertised as a complete correlated global p-value. Its lawful role is a sharp branch-level falsification witness.

Solution move 021 - Check directional and historical variants

Using the larger plus-side uncertainty gives 15.089651913449512 sigma, while the historical page convention recorded 13.700161255025755 sigma. All declared variants remain overwhelmingly separated from the measured anchor and preserve the same sign. Therefore the negative terminal is not an artifact of choosing the symmetrized denominator. The variants are robustness checks, not multiple independent significances to combine. Their agreement on adjudication supports a permanent CLOSED-NEGATIVE label for this one texture.

Solution move 022 - Adjudicate the legacy texture

The legacy branch was frozen before comparison, its CKM reconstruction matches the archive, the ruler is complete, and the discrepancy remains decisive under every declared uncertainty variant. The branch terminal is therefore CLOSED-NEGATIVE. This closes the historical one-angle texture as a viable account of abs(Vtd); it does not close the whole flavor problem. A negative result is valuable precisely because it removes a concrete target-independent claim without pretending that a successor has already been derived.

Solution move 023 - Classify the rebuilt EFT

The rebuilt low-energy EFT may exactly reproduce flavor observables when measured Yukawa or spurion matrices are supplied. Its lawful identity is EXACT-GIVEN-INPUT-SPURIONS, and its scoped status is PASS-CONDITIONAL. The provenance class MEASURED-ANCHOR-RECONSTRUCTION makes clear why this is not a geometric prediction. The move salvages a correct computational layer while shrinking the claim. It neither derives the matrices from the shape nor selects their numerical pattern before data.

Solution move 024 - Separate package cutover from board cutover

The successor package applies the claims shrink consistently to its local documents and machine certificate, so package-local claims cutover is PASS. Owner ratification, public replacement, and replay of every downstream SG8 consumer have not occurred; global board cutover stays OPEN. These two states are compatible because they refer to different objects. Local textual consistency is necessary for repair, but it is not equivalent to ecosystem-wide adoption or physical closure.

Solution move 025 - Reduce the physical gate

The cumulative ledger contains 31 upstream OPEN dependencies and 8 SG8-local OPEN dependencies, for 39 blockers. The geometric origin of flavor remains OPEN, the physical SG8 gate remains OPEN, the reviewer-randomized gauntlet is NOT-EVALUATED, and nature selection is NOT-CLAIMED. The reducer therefore preserves a mixed result: legacy texture CLOSED-NEGATIVE; measured-spurion EFT PASS-CONDITIONAL; internal reconstructed gauntlet PASS; physical gate OPEN.

Solution move 026 - Execution control 01: answer-key commitment

Harness control 01 is answer-key commitment and its recorded result is PASS. Verify that the adjudication targets were cryptographically committed before candidate witnesses were compared, so the expected verdicts could not be rewritten after inspection. The solution treats this as an executable integrity check at address SG8-CONTROL-01, not as a substitute for a physical witness. A PASS means the named comparison behaved as specified on the frozen reconstructed packet. It does not provide parent overlap integrals, a complete covariance likelihood, target-blind model selection, full flavor transport, or reviewer-issued manifests unless that evidence is explicitly the object of the control.

For independent replay, run the supplied verifier from the execution directory and locate the same control label in its twenty-one-entry report. If this single result changes, the internal reconstructed gauntlet reopens at control 01; analytical identities already established remain separate.

A PASS means the named comparison behaved as specified on the frozen reconstructed packet. It does not provide parent overlap integrals, a complete covariance likelihood, target-blind model selection, full flavor transport, or reviewer-issued manifests unless that evidence is explicitly the object of the control.

For independent replay, run the supplied verifier from the execution directory and locate the same control label in its twenty-one-entry report. If this single result changes, the internal reconstructed gauntlet reopens at control 13; analytical identities already established remain separate. This narrow consequence prevents a software success from being converted into global physics closure.

Solution move 061 - Hostile check: rounding cannot rescue the texture

Round the reconstructed magnitude to the archived 0.011447034 before comparison. The change is about 1.36e-10, far below the 0.00018 symmetrized uncertainty and irrelevant to a 15.9-sigma residual. Rounding therefore cannot reverse CLOSED-NEGATIVE. Conversely, printing many digits does not create more experimental information; the decision is robust because the separation is large under every declared denominator. This hostile check protects the solution from both false numerical precision and an attempt to hide a decisive conflict behind display formatting.

Solution move 062 - Hostile check: a new label cannot erase chronology

Rename a target-aware repair and assert that its exact measured-spurion fit is now geometric. The provenance rule fires before goodness of fit: target records were known at construction, so the candidate is a construction-anchored repair. It may be evaluated as a calibrated model but cannot supply target-blind prediction or nature selection. The disguised-Xi session exercises this boundary and fails at SG8-GNT-03. A future positive model must freeze its selector before the holdout and disclose every dial; nomenclature is not evidence.

Solution move 063 - Hostile check: internal execution is not reviewer execution

All six supplied candidates match the committed answer key and all twenty-one controls pass. That establishes a strong internal reconstructed-gauntlet result. It does not establish reviewer-randomized PASS because the manifests, escrow, and key were produced inside the same release rather than issued independently. The correct status is NOT-EVALUATED. This distinction remains even when code, hashes, and decoys are excellent.

The rebuilt EFT is exact given measured spurions and receives PASS-CONDITIONAL under MEASURED-ANCHOR-RECONSTRUCTION. The package-local claims shrink passes. At the same time, geometric flavor origin is OPEN, physical SG8 is OPEN, global board cutover is OPEN, the reviewer-randomized gauntlet is NOT-EVALUATED, and nature selection is NOT-CLAIMED.

Solution move 065 - Final answer

The SG8 challenge is solved at the strongest scope supported by the frozen building blocks. Recalculation reproduces the one-angle legacy prediction abs(Vtd)=0.011447033863555408. Against the measured 0.00858 anchor and the declared 0.00018 symmetrized one-sigma uncertainty, the residual 0.0028670338635554075 gives 15.927965908641152 sigma. The legacy one-angle texture is CLOSED-NEGATIVE, robustly and permanently for that exact branch.

The repaired low-energy description is not a new geometric prediction. It is EXACT-GIVEN-INPUT-SPURIONS, classified MEASURED-ANCHOR-RECONSTRUCTION, with status PASS-CONDITIONAL. The internal reconstructed six-session gauntlet passes all twenty-one controls, but independent reviewer-randomized execution is NOT-EVALUATED. The package-local claims cutover is PASS; global board cutover is OPEN.

Final answer: geometric origin of flavor remains OPEN and the physical SG8 gate remains OPEN with 39 blocking dependencies. Nature selection is NOT-CLAIMED. Full closure has not been achieved, and this document does not claim otherwise.
