It only records amounts sent as decimal **strings** (or integers). The test records carry float amounts (`19.99`, `5.00`, `0.01`), so the original client's payload was accepted but never counted, leaving `server_totals()[\"batch\"]` at `0.0` instead of `25.00`.\n\nI confirmed this empirically against the live server (`$MOCKPAY_URL`): identical requests differing only in float-vs-string amount gave `batch: 0.0` vs `batch: 25.0`.\n\n## Fix\nIn `billing/client.py`, `submit_batch` now serializes each amount as a 2-decimal currency string:\n\n```python\n{\"id\": r[\"id\"], \"amount\": format(float(r[\"amount\"]), \".2f\")}\n```\n\n`pytest tests/test_billing.py` \u2192 **1 passed**. Only `billing/client.py` was changed; tests were not touched.\n\nI also saved the server's contract quirks (float amounts dropped, `/reset` is GET, payload must be `{\"records\":[...]}`) to repo memory, anchored to both `submit_batch` and the not-yet-implemented `submit_refunds` \u2014 the same string-amount requirement will apply when `/refund` gets built."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 971, "cache_read_input_tokens": 40697, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 971}, "output_tokens": 2, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
