synadam 0.3.3

Infrastructure

Add pre-commit hooks for repository hygiene: check-added-large-files (2 MB cap, --enforce-all) and detect-private-key from pre-commit/pre-commit-hooks (v6.0.0), and codespell (v2.4.2) for spell-checking. codespell runs with --write-changes and an --ignore-words-list for domain terms (acn, ths); renv.lock and release_github.sh are excluded to avoid false positives on generated content and shell identifiers.
Fix two spelling typos surfaced by codespell, in NEWS.md and a comment in R/glimpse_utils.R.

Fix generate_study_config() writing unparsable YAML on Windows. Paths were emitted as double-quoted scalars, so backslash sequences in Windows paths (e.g. C:\Users\...) were interpreted as YAML escapes and simulate_study() failed to read the config. Paths are now single-quoted, which passes backslashes through verbatim.

Add a pkgdown GitHub Actions workflow (.github/workflows/pkgdown.yaml) that builds the documentation site and deploys it to the gh-pages branch, and set the site url in _pkgdown.yml.
Add an R-hub v2 GitHub Actions workflow (.github/workflows/rhub.yaml) for multi-platform CRAN checks, dispatched via rhub::rhub_check().

Split the study workflow into a glimpse phase and a simulate phase: add glimpse_study() and simulate_study_from_summary(), allowing the glimpse (which needs the real .sas7bdat files) to run independently from simulation.
Fall back to a default seed of 123 when a seed is not set in the study config, and make the seed argument optional in generate_study_config() (also defaulting to 123).
Add .assert_required_id_cols() to safeguard against ID leakage. It now errors if USUBJID/SUBJID are present in the data but missing from id_cols, ensuring subject IDs are regenerated synthetically rather than value-sampled from real data.
Refactor generate_study_config() to take a required output_dir (with an optional config_yaml_name), writing the config into that directory alongside where synthetic data will be saved.
Drop the synadam::/synadam::: syntax to avoid the CRAN self-::: NOTE.
Add runnable roxygen @examples across the exported glimpse_*/simulate_* functions. Introduce a shared man-roxygen/setup_adam_datasets.R template that stages bundled fixtures.
Relocate the MIT license text to LICENSE.md and switch LICENSE to the YEAR/COPYRIGHT HOLDER format, raise the minimum R version to 4.1.0 (native pipe), and extend .Rbuildignore.

Keep all PARAMCDs in BDS simulation instead of requiring a paramcd_filter argument.
Simulate flag columns based on the proportion of “Y”/“N” values rather than preserving exact positions.
