 | **entailment**    | Hypothesis is a faithful, condensed or paraphrased restatement of the premise. All critical constraints, actors, conditions and scope remain intact.                                           |
 | **neutral**       | Hypothesis neither follows nor contradicts the premise. Typically introduces unverifiable or out‑of‑scope information (e.g. different institutions, expanded context, unrelated assumptions). |
-| **contradiction** | Hypothesis directly conflicts with the premise: reverses permissions/requirements, changes legal scope, numeric limits, formats, dates, or the responsible authority.                         |
+| **contradiction** | Hypothesis directly conflicts with the premise: reverses permissions/requirements, changes legal scope, numeric limits, formats, dates, or the responsible authority or both statements cannot realistically be true at the same time. |
 
 **Rule:** A single critical mismatch (date / territory / authority / format / obligation vs. optional) is sufficient for `contradiction`, even if most of the text agrees.
