+"""probe/repl.py — Live conversational REPL for the CORE Versor Engine.
+
+Usage:
+    python probe/repl.py
+    python probe/repl.py --verbose          # also prints TurnEvent trace
+    python probe/repl.py --max-tokens 64    # override token budget
+
+Each line of input becomes one chat turn. The assembled surface sentence
+(ChatResponse.surface) is printed as CORE's response. Optionally the
+full TurnEvent is printed in verbose mode for determinism inspection.
+
+Type 'quit' or 'exit' (or hit Ctrl-D) to end the session.
