It was marked *stale*, so I verified it directly against the live server rather than trusting it:\n\n- `/refund` with `amount: 12.50` (float) \u2192 `{\"status\":\"accepted\"}` but `/totals[\"refund\"]` stayed `0.0`\n- `/refund` with `amount: \"12.50\"` (string) \u2192 recorded correctly\n\nSo `submit_refunds` serializes each amount as a 2-decimal string via `format(float(r[\"amount\"]), \".2f\")`. The test reconciles to `20.00` as expected. I recorded the verified behavior back to memory.\n\nOne thing worth flagging (I didn't touch it, since it's out of scope): `billing/client.py::submit_batch` still sends raw floats, which has the same bug \u2014 if `tests/test_billing.py` isn't currently passing, that's why.
