Changes in version 1.1.0 (2026-04-25)                  

Bug fixes

  - count_valid(): multiple unblind_codes only checked first code.
    grepl(unblind_codes, desc) silently used only the first element when
    a vector was passed. Fixed with a nested vapply loop that evaluates
    every code independently.

  - collect_findings(): crashed on 0-row data frame. Assigning a scalar
    to a 0-row data frame column with $<- caused replacement has 1 row,
    data has 0. Fixed with an nrow > 0 guard; 0-row input now produces a
    valid summary_log entry with nu = 0.

  - build_reports(): all_open.xlsx could not be read back.
    readxl::read_xlsx(range = "A3:L500000") threw an error on Windows
    when the range exceeded the actual column count (10 columns).
    Replaced with skip = 2 which auto-detects the column count.

  - build_reports(): date parsing failed for ISO string dates. FIND DATE
    was stored as an ISO string ("2024-01-15") by openxlsx but converted
    with as.numeric() only, producing NA for every row. Added
    .parse_date_col() helper that tries Excel serial number, ISO string,
    and ddMMMYYYY format in sequence.

  - build_reports(): [Was closed but re-appeared] applied to all rows.
    The auto-note condition checked the already-reassigned status rather
    than the original status from the previous run. Fixed by preserving
    old_status before reassignment and checking it in the auto-note
    logic.

  - build_reports(): NA visit IDs failed to match in merge(). merge() in
    R does not match NA == NA. Fixed using a -1 sentinel value before
    every merge, restored to NA after.

  - build_reports(): duplicate auto-tags accumulated across runs.
    Re-running multiple times appended the same tag with different
    dates. Fixed by stripping existing tags of the same type before
    appending the updated one.

  - run_checks(): check scripts could not find collect_findings().
    new.env(parent = baseenv()) cut off the rCoreGage namespace from the
    check script's lookup chain. Fixed to new.env(parent =
    environment()) so all exported package functions are visible inside
    check scripts.

  - run_checks(): removed <<- global environment modification. The
    previous local({}) + <<- pattern was replaced with new.env() +
    sys.source() to comply with CRAN policy prohibiting modification of
    the global environment.

CRAN compliance

  - All \dontrun{} examples replaced with \donttest{}.
  - All @examples blocks are now fully self-contained using tempdir()
    and system.file() no project setup required to run them.
  - stringr removed from Imports field (was declared but never called).
  - utils::read.csv() qualified; importFrom(utils, read.csv) added to
    NAMESPACE.
  - utils::globalVariables(".data") added in R/globals.R to suppress R
    CMD check NOTE for dplyr column references.
  - setNames() calls replaced with structure() and names() <- to avoid
    undeclared dependency on the stats package.
  - Bare dplyr column references replaced with .data$ pronoun in
    run_checks().
  - DESCRIPTION: software name 'Excel' quoted; all acronyms (DM, MW,
    SDTM, ADaM, CDISC) expanded; CDISC reference URL added; Description
    field restructured to end with a complete sentence.
  - Roxygen @description in runner.R: check_<rule_set> angle brackets
    replaced with check_RULESET to prevent LaTeX PDF build errors.
  - vignettes/getting-started.Rmd: hardcoded C:/Projects path replaced
    with tempdir().
