Sequences

Call arrows identify checked targets; loop and branch frames determine when they run. Open that target’s module to follow its implementation. Branches describe alternatives; loops describe repeated work. Native calls and interface dispatch stop at their declared contracts. Exit notes end that path; enclosing recovery and cleanup remain visible.
