Overview

Collection of Branch descriptors. Exposes the guard/regular/total/+ interface the rest of the cop (and PrivateMethodCallGraph) relies on —a sequence of guard clauses (‘return/raise/next … if/unless`) shares a single “all guards pass” fall-through counted once per method (see #branches_from) rather than once per guard. `with_origin` tags inlined branches as the call graph descends into single-use helpers.
