Implements the Representation-Level Control Surfaces (RLCS) paradigm for ensuring the reliability of autonomous systems and AI models. It provides three deterministic sensors: Residual Likelihood (ResLik) for population-level anomaly detection, Temporal Consistency Sensor (TCS) for drift and shock detection, and Agreement Sensor for multi-modal redundancy checks. These sensors feed into a standardized control surface that issues 'PROCEED', 'DEFER', or 'ABSTAIN' signals based on strict safety invariants, allowing systems to detect and react to out-of-distribution states, sensor failures, and environmental shifts before they propagate to decision-making layers.

The Bayesian modelling of relative sea-level data
    using a comprehensive approach that incorporates
    various statistical models within a unifying framework. 
    Details regarding each statistical models; 
    linear regression (Ashe et al 2019) <doi:10.1016/j.quascirev.2018.10.032>, 
    change point models (Cahill et al 2015) <doi:10.1088/1748-9326/10/8/084002>, 
    integrated Gaussian process models (Cahill et al 2015) <doi:10.1214/15-AOAS824>, 
    temporal splines (Upton et al 2025) <doi:10.32614/RJ-2024-018>, 
    spatio-temporal splines (Upton et al 2025) <doi:10.32614/RJ-2024-018> and
    generalised additive models (Upton et al 2025) <doi:10.1093/jrsssc/qlae044>.
    This package facilitates data loading, 
    model fitting and result summarisation.
    Notably, it accommodates the inherent measurement errors
    found in relative sea-level data across multiple dimensions,
    allowing for their inclusion in the statistical models.

Optimize and compress local and online image files with the
    'reSmush.it' 'API' <https://resmush.it/api/>. Process individual files
    or entire directories. The 'API' is free for personal use, accepts
    files smaller than 5 'MB' and supports 'PNG', 'JPEG', 'GIF', 'BMP' and
    'TIFF' files.

Utility functions to download data from the 'RESOURCECODE'
    hindcast database of sea-states, time series of sea-state parameters
    and time series of 1D and 2D wave spectra.  See
    <https://resourcecode.ifremer.fr> for more details about the available
    data.  Also provides facilities to plot and analyse downloaded data,
    such as computing the sea-state parameters from both the 1D and 2D
    surface elevation variance spectral density.
