MDPE.20:3.2 - Recover present practice without turning one trace into prevalence

Use only current results that can change the trajectories or decision. Possible inputs include:

  • the bounded practice and project focus from MDPE.8 and MDPE.1;
  • live variants and alternatives from MDPE.9 and MDPE.16;
  • performer capability and context sensitivity from MDPE.10;
  • observations from MDPE.12;
  • recognition-and-selection arrangements from MDPE.13;
  • practice-conflict decisions from MDPE.14;
  • receiving enactment and transmission from MDPE.17;
  • cultural memory and lineage evidence from MDPE.18;
  • present continuation tests from MDPE.19; and
  • support arrangements from MDPE.22.

These are conditional inputs, not a lifecycle or mandatory checklist. A lineage story, archive count, enrolment figure, streaming trace, competition result, platform impression, press corpus, university syllabus, or expert estimate may be useful evidence for a named claim. None alone establishes enacted prevalence or continued reproduction.

When direct evidence is too costly or absent, use the best available expert estimate with its basis, uncertainty, and update condition. Do not demand an infeasible population study merely to avoid making a bounded decision.
