Post-CRAN development and 2026 workshop materials

[Pascal-Kueng]

Summary

• Integrate the post-CRAN package development (version 0.1.0.9000), including generated-column/API refinements, GMC predictors, prepared-data summaries, covariance recovery updates, and the compare_nested_models() rename.
• Add and revise the 2026 Charité Summer School workshop slide decks, exercises, tracked datasets, setup/support scripts, and teaching materials.
• Keep the Quarto and R Markdown sources authoritative: Actions now regenerate workshop slides, vignette articles, PDF exports, and the combined ZIP instead of tracking generated HTML.
• Remove the remaining generated standalone dev HTML and refresh development notes for the accepted v0.1.0 release and current public API.

User and developer impact

• The workshop remains available at the stable pkgdown workshop URL.
• Workshop-related changes rebuild and validate both HTML slide decks, PDF exports, standalone exercise sources, datasets/support files, and the combined ZIP.
• Package-only pushes to main preserve the already-published workshop directory during the clean pkgdown deployment instead of rerendering the workshop.
• Pull requests whose complete diff includes workshop materials rebuild and validate those outputs without deploying them.
• Package users receive the documented development-version API and data-preparation improvements.

Validation

• Both workshop .qmd sources render successfully with no committed slide HTML present.
• R CMD build --no-manual . succeeds and regenerates all four vignette HTML articles from their .Rmd sources.
• The standalone paper-outline .Rmd renders successfully through all 17 chunks into a self-contained HTML file in a temporary directory.
• Workflow YAML parsing, relative-link and ignore-rule checks, git diff --check, staged asset checks, and ZIP-integrity checks pass locally.

Before merge

• Review package implementation, API, tests, manuals, and example-data changes.
• Remove and ignore the accidental tracked Rplots.pdf.
• Delete .github/workflows/workshop-draft.yaml.
• Remove generated workshop, vignette, and standalone developer HTML from version control and ignore regenerated copies.
• Refresh stale pre-CRAN, API-name, and DSM-status development notes.
• After merging, verify the exact main pkgdown run, downstream Pages deployment, stable URLs, and ZIP manifest.
