Source-byte reconciliation and job-level robustness of a cross-platform qubit-space null test

Reproducibility package for a source-byte reconciliation and job-level robustness audit of the cross-platform qubit-space null test reported by Rybotycki et al. The sole authoritative data input is the corrected public record at doi:10.5281/zenodo.21775462. The package reproduces all 54 archived author-summary blocks and records the frozen 26/25/1/28 statistical classification, exact provenance, deterministic analysis code, validation tests, manuscript and supplementary information. The labels are statistical and do not identify a device mechanism, Hilbert-space dimension or new physics.
