MAV-MCC 4S+4T UGT - LHCb G-perp Prospective Prediction Freeze v0.1-R0

This record publishes the ex-ante prospective prediction freeze MAV-UGT-LHCb-GPERP-P1-v0.1-R0 within the MAV-MCC 4S+4T Unified General Theory research framework. The protocol converts an exploratory four-body geometry identified in LHCb Request #67 into a fixed prediction to be tested without post-unblinding retuning. Requests #67 and #80 are treated strictly as calibration and protocol-development datasets. The primary observable is the leave-gate-out coordinate G_perp = D1 / D3, constructed from Lorentz-invariant pair-affinity variables. The frozen LOW selector is m²(p_same pi_same) <= 2.011466 GeV² inside the fixed Lambda_b signal window |M_parent - 5619.6 MeV| <= 25 MeV. The principal prospective requirement is Q_G = median(G_perp | LOW) / median(G_perp | REST) <= 0.60, together with the predeclared directional conditions D1_LOW < D1_REST, D3_LOW > D3_REST, and the same LOW-versus-REST G_perp direction separately in MagUp and MagDown data. The first execution target for the present G_perp P1 protocol is LHCb Request #84, production MAV_MCC_ABB_LOW_STEP3_2015_Lb_pKpipi_v1, corresponding to the 2015 BHADRON.MDST MagDown and MagUp samples for the Lambda_b0 -> p K- pi+ pi- decay and charge-conjugate mode. Request #84 is a previously analysed corpus under a different MAV-MCC Step-3 LOW-network protocol based on the frozen N1 and N2 observables. It is therefore not classified here as unseen-data blind validation. The present P1 test is ex-ante with respect to the newly frozen D1, D3, G_perp and Q_G observables. These quantities were not defined as primary judging observables in the earlier Request #84 protocol. No result from that earlier analysis is used to tune, modify or rescue the present G_perp prediction. Accordingly, the methodological status of the present execution is: EX-ANTE FOR THE NEW G_perp STATISTIC / PREVIOUSLY ANALYSED CORPUS / NOT UNSEEN-DATA BLIND VALIDATION. All P1 observables, thresholds, polarity requirements, bootstrap settings and PASS/FAIL rules were publicly frozen before the present G_perp execution. The protocol, thresholds, observable definitions, bootstrap procedure and decision rules are fixed. If required variables are unavailable, the outcome is classified as TECHNICALLY INCOMPLETE or NOT EXECUTABLE rather than modifying the prediction. P1 is classified as PASS only if the combined Q_G satisfies the frozen Q_G <= 0.60 requirement, the frozen D1 and D3 directional conditions are satisfied, the LOW-versus-REST G_perp direction is reproduced independently in both MagUp and MagDown data, and the upper endpoint of the frozen 99% bootstrap interval remains below Q_G = 1. The bootstrap uses 10,000 resamples with RNG seed 670087 and preserves the original MagUp LOW, MagUp REST, MagDown LOW and MagDown REST stratum sizes. A PASS of this protocol would establish prospective transfer of the predeclared G_perp geometry only. It would not by itself constitute unique validation of MAV-MCC/UGT, since hadronic resonance structure, strong-phase interference, four-body phase-space correlations, acceptance effects and detector/reconstruction effects remain conventional competing explanations. The test does not claim direct observation of an upstream native frequency, direct observation of coherence, direct observation of T1, T3 or T4, new CP violation, an antiuniverse or antimatter-escape effect, extra physical spacetime dimensions, or exclusion of standard hadronic resonance physics. Historical verdicts for Requests #67, #80 and #91 remain unchanged. Correction note — 1 October 2026: The initially published v0.1-R0 metadata and freeze document incorrectly identified the execution target as LHCb Request #87. The correct identifier is LHCb Request #84. This is strictly a provenance and request-identifier correction. No scientific parameter, observable, threshold, signal window, LOW definition, polarity requirement, bootstrap setting, statistical criterion or PASS/FAIL rule has been changed. The original public deposit timestamp therefore remains the pre-P1-unblinding timestamp for the G_perp hypothesis.
