E.17.AUD:5.4 - Explanation-laundering case
An onboarding explainer starts from one stable source-pinned note, but then the simplified prose begins to sound like canonical assurance or policy. The publication unit may still be readable, yet the main problem situation is no longer publication-unit stability. Leave publication-unit stability and use E.17.EFP’s simpler source-linked boundary sentence first; instantiate ExplanationFaithfulnessProfile only when explanation-class ambiguity still changes the next action.
