F.12:15.2 - Regression

  • RSCR-F12-E01 (relation update). A changed indicator, evidence, or semantic relation affects only evaluations that depended on it.
  • RSCR-F12-E02 (edition change). Source-local meaning remains tied to the edition used by each evaluation.
  • RSCR-F12-E03 (population drift). New population definitions create explicit new evaluations.
  • RSCR-F12-E04 (window partition). Weekly and monthly results and statuses remain distinct; any roll-up states its aggregation.
  • RSCR-F12-E05 (indicator retirement). Direct measurement changes future evaluations without silently rewriting prior indicator-dependent results or assertions.
