abstract: 'Implements policy evaluation primitives from HM Treasury Magenta Book guidance
  (HM Treasury, 2026): theory of change and log-frame construction, evaluation planning
  and stakeholder mapping, power and minimum-detectable-effect calculations for randomised
  designs (including cluster and stepped-wedge designs following Hussey and Hughes
  (2007) <https://doi.org/10.1016/j.cct.2006.05.007> and Hemming et al. (2015) <https://doi.org/10.1136/bmj.h391>),
  Maryland Scientific Methods Scale ratings, structured confidence ratings, light-weight
  difference-in-differences and interrupted-time-series estimators (Bernal et al.
  (2017) <https://doi.org/10.1093/ije/dyw098>) with cluster-robust standard errors
  (Cameron and Miller (2015) <https://doi.org/10.3368/jhr.50.2.317>), pre-treatment
  balance checks (Stuart (2010) <https://doi.org/10.1214/09-STS313>), and cost-effectiveness
  analysis (cost per outcome, incremental cost-effectiveness ratio, acceptability
  curves, incremental net benefit, quality-adjusted and disability-adjusted life years).
  Designed as the evaluation companion to the appraisal package ''greenbook''. Bundled
  rubric and reference tables carry vintage metadata for reproducibility. Aligned
  with the May 2026 republication of the Magenta Book.'
