 ## Ideas
 
-No ideas are currently awaiting selection. Active feature work belongs in its
-focused roadmap rather than this catalog.
+### Remaining Standard Policy Alignment
+
+Review the internal standard's architecture and testing clarifications about
+adopted constraints, threat scope, and tests that must not invent contracts.
+Adapt relevant guidance to Promptkit's library boundaries without introducing
+new runtime restrictions or release gates. This is separate from the completed
+licensing-documentation alignment.
