So a naive port of `submit_batch` (which posts float amounts) would return \"accepted\" yet reconcile to `0.0`.\n\nI discovered this by probing the live server:\n- float `12.50` \u2192 dropped \u2192 `refund: 0.0`\n- int `1250` (cents) \u2192 taken literally \u2192 `refund: 2000.0` (wrong)\n- string `\"12.50\"` \u2192 parsed correctly \u2192 `refund: 20.0` \u2705\n\n`submit_refunds` POSTs to `/refund` with each `amount` serialized as a string (`str(r[\"amount\"])`), so the totals reconcile to `20.00`. I documented the float-drop trap in the module docstring. Only `billing/refunds.py` was changed; tests were not modified.\n\n**Heads-up (out of scope):** `tests/test_billing.py` is **failing independently** of my change. It exercises `billing/client.py::submit_batch`, which I did not touch \u2014 and `/batch` has the *same* float-dropping behavior, so `submit_batch` sending float amounts now reconciles to `0.0` instead of `25.00`. This is a pre-existing failure in session 1's `client.py`, not a regression from my work (test_billing doesn't import `refunds.py`). If you'd like, I can apply the same string-amount fix to `client.py` to make test_billing pass too \u2014 but that's outside the stated task, so I left it alone."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 490, "cache_read_input_tokens": 41187, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 490}, "output_tokens": 1, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
