Improved package-check readiness by excluding prompt/planning artifacts from package build inputs via .Rbuildignore.
Updated LICENSE stub to valid DCF format for MIT + file LICENSE metadata.
Added explicit global variable declarations used in tidy-eval pipelines to avoid R CMD check NSE notes.
Expanded unit tests substantially for core helpers (selection/index/row/text/blank-line behavior).
Added dedicated regression tests for %>% pipeline behavior, including select_correct_range() output and selection side effects, to support safe future migration from %>% to |>.
Consolidated duplicate index helper definitions in R/rs_get_index.R into single implementations and removed superseded suffixed variants while preserving first/last/all selection behavior.
Modernized package baselines in DESCRIPTION (R (>= 4.1), testthat (>= 3.0.0), Config/testthat/edition: 3) and moved rstudioapi to Imports.
Confirmed GitHub Actions as the sole active CI path and removed Travis maintenance remnants.
Refreshed README wording and install guidance, removed stale date badge, and updated logo source branch links in both README.Rmd and README.md.
Added lightweight lint configuration via .lintr and set styler addin default transformer with strict = FALSE in .Rprofile.
Renamed visual-editor helper to is_visual_editor() and documented is_rmd_visual_mode as a backward-compatible alias.
Added a CRAN submission checklist and downstream deprecation migration guidance under .github/.
Added GitHub Actions lint workflow to run lintr and a non-destructive styler check.
Added a release prep helper script in data-raw/release-prep.R, a support matrix note under .github/, and a helper-family vignette for onboarding and discoverability.
Added a maintainer-facing revdep smoke-check helper in data-raw/revdep-smoke-check.R and documented when to run it before release tagging.
Expanded downstream deprecation guidance with an explicit timetable for is_rmd_visual_mode() and future compatibility wrappers.
Expanded the helper-family vignette with concrete examples for common addin tasks and a build-time package setup chunk.
Added a helper-family link to the README so discoverability paths surface the new vignette from the package homepage.
