Paper UAP-K: Temporal and Spectral Structure in an Instrumented Ball-Lightning Record Public-Data Reconstruction, Mechanism Identifiability, and a Prospective Holosphere Corridor Tes

Abstract

Ball lightning is a long-reported atmospheric phenomenon for which rare instrumented records remain especially valuable. This paper examines one reported natural event that followed a cloud-to-ground lightning strike and was recorded by two slitless spectrographs at an approximate range of 0.9 kilometers. Publications issued in 2014, 2018, 2022, and 2025 are successive analyses of this single event rather than independent replications. The present study reconstructs the public numerical products deposited for the 2025 analysis and determines whether those products can adjudicate a history-dependent Holosphere transport-corridor mechanism. The reviewed program verifies all ten deposited source files against a frozen byte-count and SHA-256 ledger, checks the expected embedded legend tokens and deposited column-order consistency used for the principal species assignments, reparses five Origin project files into 67 numerical datasets, and inventories 64 cropped spectral strips. The restricted parser does not independently decode the complete Origin graph-object binding. All twelve fixed validation checks pass. The reconstructed mean radiation-power densities agree within one percent with the source-paper approximations: about 374 million watts per square meter for neutral oxygen, 30.3 million watts per square meter for neutral silicon, and 25.7 million watts per square meter for neutral iron. The line-intensity table has unequal data availability, with 31 observed neutral-oxygen values, 22 neutral-nitrogen values, and 32 values each for neutral silicon and neutral iron. Both the available-observation comparison and an identical-row comparison restricted to the 22 rows containing all four lines show the same qualitative pattern: the oxygen and nitrogen emissions are much more variable than the silicon and iron emissions. A robust median-based sensitivity analysis preserves this ordering. The supported result is therefore a descriptive contrast between the dispersion of the air-related and soil-related spectral lines, not the identification of two unique physical states or mechanisms. A post-inspection gap rule divides the deposited neutral-oxygen power values into nine contiguous data runs with a median run-start spacing of 10.3335 milliseconds, corresponding numerically to 96.77 cycles per second. The nine-run result persists for gap thresholds from one to five milliseconds, while a half-millisecond threshold produces eleven runs. These are runs in a processed data deposit, not independently detected physical pulse onsets in a complete raw waveform. No physical period, natural constant, or Holosphere frequency is inferred. Paper K6 defines corridor memory as a bounded spatial field produced specifically by successful admissible transport and modified by leakage and diffusion. The public ball-lightning packet does not measure the three-dimensional parent-lightning channel, a synchronized trajectory of the emitting region, local electric and magnetic fields, channel temperature, electron density, conductivity, space charge, or an independent event-level holdout. A generic source-and-decay memory recurrence is not specifically Holosphere evidence when an ordinary electrical-discharge model can use the same recurrence and observational freedom. A distinct corridor test requires measured source and support variables and predictive improvement beyond ordinary lightning-channel and plasma memory. Paper UAP-K therefore supports reproducible public-data reconstruction and a robust descriptive spectral-dispersion contrast. Spatial corridor reuse remains not adjudicated, and this event does not test or validate a Holosphere mechanism. The paper instead supplies a prospective model ladder, control structure, instrumentation requirements, and theory-modification rules for future multi-event lightning and ball-lightning measurements.
