+- R2 (P1): `check_stock` must complete within 250 ms. On origin timeout the

+- R3 (P1): Regression cases must cite the source trajectory ID and the exact

+# Live diagnosis experiment architecture
+
+The orchestrator calls a local HTTP order service. Refund flows MUST call
+`verify_refund_eligibility` before `process_refund`. Inventory origin calls
+have a 250 ms client deadline; on timeout the orchestrator MUST call the same
+`check_stock` operation through the degraded cache route and finish normally.
+Every trajectory turn records its measured HTTP latency and raw response.
