Datasets and results tables for "Sensor–rock coupling controls capacitance-based measurement of water content in intact rock: calibration and agreement analysis on limestone and phyllite"

Primary datasets and derived results tables supporting the manuscript on sensor-rock coupling in capacitance-based water-content measurement of intact rock (limestone and phyllite; HPC-75 fringing-field capacitance sensor). This deposit contains data and values only (no code, no narrative documents). Contents: data/ - the archival specimen master (specimens.csv; 156 specimens, one row per specimen) and the raw replicate logger archive (readings_long.csv; 9,644 readings); results/ - per-analysis CSV tables (descriptives, per-dataset and pooled calibrations, leave-one-specimen-out and leave-one-state-out cross-validation, Bland-Altman and concordance agreement, physics-based mixing models, series-capacitance grids, GUM Monte-Carlo uncertainty budget, principal component analysis, group tests, and the pre-registered porosity-aware calibration test); results/figure_data/ - the exact numerical data underlying each manuscript and supplement figure; results/ledger/ - the numeric claim ledger (ledger_master.csv and addenda) mapping every reported quantity to its value; and SHA256SUMS.txt - SHA-256 checksums for every file. The program spans two lithologies and three sensor-rock coupling classes (surface-insulator contact, ~1 mm air gap, and ~1.5 mm in-hole insertion); 156 specimens with 153 complete voltage-reference analysis rows. Column headers are self-descriptive, with units noted in the header names (e.g. saturation_index_pct, porosity_pct, sensor_voltage_V).
