Rather than trust it blindly, I **probed the live service**:\n\n| Sent | Server refund total |\n|------|--------------------|\n| float `19.99` | `0.0` (silently dropped) |\n| string `\"19.99\"` | `19.99` \u2713 |\n| int `1999` | `1999.0` (wrong scale) |\n\nSo the memory's core claim still holds for `/refund`: the service only reconciles amounts serialized as decimal strings. My implementation sends `{\"amount\": str(r[\"amount\"])}`, mirroring `submit_batch`'s shape but with the string fix. The test (12.50 + 7.50 \u2192 refund total 20.00) passes.\n\nI updated the stale memory with the re-verified probe results and flagged that `client.py:submit_batch` currently sends raw floats \u2014 so if `test_billing` is failing, it likely needs the same `str()` fix (that's outside the scope of what you asked, so I left it untouched)."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 1077, "cache_read_input_tokens": 33711, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 1077}, "output_tokens": 4, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
