+## Promotion Boundary
+
+Do not move this into `tests/` until:
+
+- the exact book passage or external artifact is cited;
+- Raman ayanamsa mode and dasha-year policy are frozen;
+- the engine call is real, not a mock;
+- the tolerance is explicit and reviewed.
+
+Until then it is a benchmark/oracle draft only.
