           1. Return true.

+      : Input

+      : Output
+      :: a boolean
+
+      Note: Router conditions can be complex and nested using {{RouterCondition/_or}} and {{RouterCondition/not}}. To prevent excessive processing, this algorithm introduces two limits. First, the total number of conditions, counting all nested conditions, cannot exceed 1024. Second, the nesting depth is limited to 10 levels to avoid exponential computation.
+
+      1. Let |result| be a [=count router condition result=].
+      1. Set |result|'s [=count router condition result/total count=] to 0.
+      1. Set |result|'s [=count router condition result/depth=] to 1.
+      1. Let |maxCount| be 1024.

I think the latest commit simplified the flow and addressed the comment.
