+### Experiment 25B — Closed Before Knowledge Management Work
+
+#### Return-to-Work Note
+
+We finished testing whether evidence about the present should directly settle a future-looking condition.
+
+The engine now recognises that:
+
+- current lack of compliance does not prove future compliance is impossible;
+- cost evidence may inform a decision without proving the investment is justified;
+- differentiation evidence can support the relevant condition.
+
+The current language matching is provisional and based on narrow phrases. Do not continue adding synonyms as the long-term solution.
+
+Engine experiments are now paused while project knowledge and context-loading are rationalised.
