A Cross-Domain Dual-Sector Spectral Fingerprint: Paper, Methods, and Reproducibility Materials

This paper A Cross-Domain Dual-Sector Spectral Fingerprint together with supporting reproducibility materials. The work reports a reproducible cross-domain spectral pattern detected under a fixed scan protocol across selected coherent and dissipative physical systems, together with null-domain comparisons and a bounded operator-theoretic interpretive framework. The deposit includes manuscript sources, supporting ledgers, and associated research materials intended to document theorem status, computational provenance, source provenance, and replication structure.

The paper presents two complementary sector profiles, a fixed constant library, audited anchor systems, and explicit limits on present claims. It does not claim a proof of universality; rather, it documents a structured empirical pattern, its reconstruction constraints within the classes tested, and the open mathematical conditions that remain. The materials are provided to support transparency, inspection, and independent reproduction of the reported results in standard computational environments.
