## 📊 Data Availability for Submission

**Statement:**
> Metabolomics raw data (mass spectrometry files) and CT DICOM archives (7,686 slices) are available from the corresponding authors without restriction. Processed metabolomics abundance tables, CT feature matrices, and all analysis scripts are publicly accessible at https://palm.suncx.top (DOI pending upon Zenodo deposition). Interactive tools—including a CT viewer, metabolic network browser, variety comparison dashboard, and germination predictor—are hosted at the same URL for community use.
