PSDA.Reference:13 - Keep source changes and case changes distinct

When a fact about one person, organization, model or provider changes, reconsider the opportunity or advice that depended on it. A changed human career-service condition affects the human engagement, assessment or return that used it; a changed consulting disclosure condition affects the applicable service. Keep the independent evidence for other subjects and conclusions.

Revise the reusable method when new evidence or a better approach changes its search, opportunity construction, dependency reasoning, reachability test or stopping rule. The maintainer of the affected advising or opportunity Method retains the changed claim, its source, the affected contribution and the revised limit. Reopen a wider PSDA contribution when one of its shared inputs or results changes.

A person using advice keeps the relevant subject, configuration, intended use, period and source conditions visible. Actual service relationships determine consent, confidentiality, competence, referral and closure duties. Apply the duties established for that relationship, and obtain a missing professional or technical result before relying on the affected conclusion.

The source responsibility and references identify the relied-on sources, while the subject-specific supplier account identifies the contribution whose local use may need to change.
