E.17.EFP:6 - Bias-Annotation

Scope: Conditional where explanation-class ambiguity changes use. External source grounding is limited to generated, model-facing, retrieval-facing, or interactive explanation; ordinary human-authored use remains a local design branch with a simpler-note non-use default.

The profile biases toward source restraint and against overread. Its counter-bias is the E.17.EFP:5.7 task replay: do not apply the profile when a shorter source-linked boundary sentence performs the human task equally well.
