-The `next` and `stepIn` requests are wired to Priroda's existing source-line
-step so VS Code can drive one visible step. They are not true DAP step-over or
-step-in semantics yet.
+DAP supports `stepIn`, `next`, and `stepOut`. `stepIn` stops at the next
+displayed source location and can enter calls when the callee has a distinct
+displayed source position. `next` steps over calls by tracking the starting stack
+depth, and `stepOut` runs until execution reaches a shallower user frame.
+`stepOut` from the outermost user frame is rejected. This is still
+single-threaded and source-position based, not the full future thread/frame
+model.
