What this error means
Several Command classes may share a path prefix, but each command node must have one unambiguous feature-option scope. If a shared node contains branches but no executable endpoint, comes from more than one owner Module, and at least one of those Modules declares options, func cannot decide which options to expose at that node.
details.path identifies the ambiguous shared path. details.modules lists the owner Modules contributing to it.
How to fix it
Move the Commands sharing that path into one feature Module, or move options that should apply to every branch into the root Module. If the branches should not share a scope, change their Command paths so each feature has a distinct prefix before the ambiguity occurs.
