Data and Code for: Forward-Only Temporal-Coherence Occupancy Regimes in Atlantic Tropical Cyclone Intensity Evolution (1851–2024)

# Version 4.0 record description This package reproduces the corrected V2 analysis for “Forward-Only Temporal-Coherence Occupancy Regimes in Atlantic Tropical Cyclone Intensity Evolution (1851–2024).” The algebraic reduction from pairwise agreement to a common-sign representation was numerically neutral when applied to unchanged historical state semantics. Two subsequent activation corrections were material: no active label or occupancy is assigned to the first coherent advisory, and confirmation requires the same nonzero direction at consecutive advisories, so reversal resets confirmation. The 54,174-row public materialization and portable code regenerate the V2 detector, RI labels, descriptive stratification, five-advisory comparator, signed timing, separate null-family summaries, duration models, and all current manuscript tables and figures. Results and claims were regenerated and narrowed. RI is a downstream outcome only. This package is descriptive and is not an operational forecast model or physical storm-structure retrieval. Version 3.2 is retained as historical lineage and is superseded for reproduction of the current manuscript. The exact environmental model matrix is not redistributed because explicit redistribution authority was not locally verified; the schema, formulas, hashes, and expected outputs are supplied.
