+"gradient" (patches) to the current skill document to produce an updated
+candidate skill.

+Modules
+-------
+- skill: edit application (optimizer.step() / parameter update)
+- clip: edit ranking and selection (gradient clipping)
+- slow_update: longitudinal comparison and guidance (EMA / regularization)
+- meta_skill: cross-epoch memory for optimizer context
