Supplemental Material for The Chemistry Performance Envelope: Circuit resources, energy prediction and conditional processor budgets Pally Sai Tilak, Atomic Cubit; tillaksai@gmail.com CHEMISTRY_ENVELOPE_SUPPLEMENT.pdf: data conventions, circuit and energy comparison, full hydrogen campaign, repeat estimates, conditional processor budgets and reproducibility procedure. RESEARCH_DATA.zip: selected source records and documented extracts, reduced circuit and Pauli operator, result/calibration inputs, numerical reproduction scripts, plotting code, README and hash manifest. Read the PDF with a standard PDF reader. Extract RESEARCH_DATA.zip and follow its README.txt for offline Python reproduction. NumPy and SciPy support numerical checks; matplotlib supports plots; Qiskit is optional for a second circuit implementation. No complete original hardware execution or all original benchmark optimizations are claimed to be reproducible from these records. The scope is stated in the manuscript and archive README.
