Frozen Numerical Evidence and Independent Audit for a Four-UAV Flexible-Net Catching Study

This dataset provides a non-production, frozen-record evidence archive for a pure numerical study of a four-UAV flexible-net system for high-altitude emergency catching. It contains synthetic input and configuration snapshots, processed contact-state and residual records, deterministic-repeatability summaries, the P1.19 paired system endpoint, rounded figure-value tables, an evidence index (S1), file-integrity manifests, and two independent Python audit files for inspecting stored P1.53/P1.55 records. The original numerical records and audit code are retained unchanged; preparation of this release did not rerun an experiment or the production solver. The archive is intended for inspection of the included evidence and independent numerical checking of stored records. It is not the complete production simulator and does not demonstrate external reproduction of the original simulation pipeline. P1.51's original runtime audit is unavailable. P1.49 and P1.50 remain blocked, and production_merge_recommendation=NOT_AUTHORIZED remains in force. The preserved Figure 3 values have a documented maximum discrepancy of approximately 0.85% from the current analytical force screen; their full-precision historical source is unavailable. These values support qualitative trends rather than exact agreement with the current formulas. All conclusions are limited to numerical modeling and frozen-record auditability. No real-flight performance, human safety, real-time execution, airworthiness, structural certification, or deployment readiness is established.
