-## Result: live R parity diverged
+## Result: manual review required
 
-Mapped parity tests recomputed every R value from the freshly installed live R NNS and the Python implementation did not match. Public Python behavior differs from live R at the recorded commit.
+The plan reports unmapped R files. A human must extend `sync/r_api_map.json` before automated parity can run:
