herald 0.0.0.9000

Breaking changes

  • write_xpt(): name parameter renamed to dataset for API consistency.

New features

  • validate() gains files= parameter for explicit multi-file cross-dataset validation.
  • validate() and submit() gain ct_path= parameter for one-off custom controlled terminology without session registration.
  • New register_ct(), clear_ct(), list_ct() for session-level custom CT registry management.
  • submit() generates HTML + XLSX conformance reports alongside the submission package.
  • Submission Readiness banner in HTML report now only activates when conformance rules have actually run.

Validation engine

  • Cross-dataset aggregate operator: added gte/lte operators; negation now correctly flags violations (not compliance).
  • build_anchor_index() is fully spec-driven via 4-tier heuristic — no hardcoded dataset or variable names.

  • Operator bug fixes synced from heraldrules: HRL-SD-010/011/014, HRL-TS-002/004.
  • 269 new rules added across FDA, PMDA, and CDISC CORE engines.

  • pkgdown site at https://vthanik.github.io/herald/.
