Reproducibility package for the paper "Characterising Quantum Randomness under Classical Rejection Sampling in Quantum-Backend-as-a-Service Architectures: A Readout-Mitigated Hardware Study with a Fair-Dice Case Study." Contains the production circuits, seeded experimental data, analysis and figure-generation scripts, the FastAPI quantum-dice service, and the LaTeX manuscript sources. All simulator results are bit-for-bit reproducible (seed_simulator=42). MIT-licensed. v1.6–v1.7: camera-ready typesetting (numbered equations, prose contributions, uniform figure widths, algorithm float) and a production-quality service- architecture figure. No changes to code, data, or reported results vs. v1.5.
