The `/batch` POST always returns `{\"status\": \"accepted\"}`, which masked the real problem: I probed the live server directly (GET `/reset` \u2192 POST `/batch` \u2192 GET `/totals`) and found the payments service **only adds a record's `amount` to its totals when `amount` is a JSON string**. As a JSON number (float) it's silently recorded as `0.0`; as an int it's summed literally with no cents conversion. The client was serializing `amount` as a float.\n\n## Fix\n`billing/client.py`, `submit_batch` \u2014 encode the amount as a string in the payload:\n\n```python\npayload = {\"records\": [{\"id\": r[\"id\"], \"amount\": str(r[\"amount\"])} for r in records]}\n```\n\nI left a comment explaining the non-obvious contract and recorded it in repo memory, since `refunds.submit_refunds` is still unimplemented and will hit the same trap. Only `billing/client.py` was changed; tests were not touched."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 918, "cache_read_input_tokens": 39463, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 918}, "output_tokens": 4, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
