GSC-X Giant Planets Complete Analysis Dataset V1

This dataset provides the complete reproducible analytical record of the GSC-X Giant Planets Multi-Visit Validation V1, performed using publicly available JWST/MIRI Medium Resolution Spectrometer (MRS) observations of Uranus and Neptune. Unlike the compact validation release, this archive preserves the entire analytical workflow, including intermediate products, quality-control decisions, rejected candidates, robustness analyses, repeatability studies and Executive Decision outputs. The objective is to provide a fully reproducible scientific audit trail rather than only the final published results. The validation was performed on 120 calibrated JWST/MIRI x1d spectra obtained from 10 independent observing visits: Uranus: 3 complete observing visits Neptune: 7 complete observing visits 12 calibrated MIRI/MRS spectral sub-bands per visit The complete analytical workflow includes: automatic observation inventory product integrity verification spectral schema validation spectral fingerprint extraction cross-object coincidence analysis science candidate catalogue generation robustness validation sensitivity and stability analysis literature association layer local spectral profile verification continuum robustness analysis candidate decision framework multi-visit repeatability analysis cross-target repeatability comparison quality guard validation Executive Decision engine publication dataset generation The complete processing generated: 490 repeatability clusters 59 strongly repeatable spectral structures 213 moderately repeatable structures 218 non-repeatable structures 12 repeatable common Uranus–Neptune features 18 robust target-specific repeatable candidates After all robustness filters and multi-visit validation, the Executive layer confirmed one reproducible target-specific spectral profile candidate: Target: Neptune Spectral band: MIRI CH2-LONG Central wavelength: 11.06755 μm Repeatability: 7/7 Neptune visits Control observations: absent in all Uranus visits Amplitude ratio: ~9.38 Executive classification: TARGET_SPECIFIC_PROFILE_CONFIRMED This result is intentionally presented as a reproducible spectral profile candidate rather than a molecular identification. Molecular attribution requires independent spectroscopic confirmation beyond the scope of the present validation. The archive intentionally preserves both positive and negative analytical outcomes, including rejected molecular associations and continuum-sensitive structures, providing a transparent and fully reproducible scientific workflow.
