Supplemental Materials and Derived Data for "Joint Feasibility of Renewable-Utilization Targets under Grid-Exchange Shape Constraints: Window–Benchmark Structure, Attribution, and Restoration"

This record contains the supplemental materials and shareable derived research outputs supporting the manuscript “Joint Feasibility of Renewable-Utilization Targets under Grid-Exchange Shape Constraints: Window–Benchmark Structure, Attribution, and Restoration.” The deposit includes Supplemental Material S1–S12, machine-readable structured-validation and restoration results, non-sensitive preprocessing provenance, figure and claim-validation records, a data dictionary, reproducibility documentation, and cryptographic checksums. Project-specific full-year planning input series, associated source data, original engineering workbooks, and the frozen full planning input are not included because their public-release rights are restricted. The deposited materials support verification of the analytical, numerical, and reproducibility claims reported in the manuscript without disclosing restricted project data.
