Rock-Armour Stability Reanalysis: Reproducibility and Validation Package

This repository provides the data products, frozen validation partitions, analysis code, diagnostic outputs, and reproducibility materials for a re-analysis of the Van der Meer (1988) rock-armour stability database. The package contains the canonical endpoint manifest, frozen Test-number-grouped cross-validation maps, primary out-of-fold predictions, 100 repeated grouped-validation results, raw coefficient estimates from 1000 training fits, physical-Test cluster-bootstrap outputs, model diagnostics, environment information, source-workbook SHA-256 information, and package hashes. The archive is intended to permit independent numerical verification of the reported predictive results. The manuscript itself is not included in this repository. All scientific calculations use full-precision coefficients. Frozen fold maps are distributed as experimental-design artefacts so that validation results do not depend on implementation-specific group allocation in different software versions.
