A repo-memory episode flagged this (marked stale since `client.py` had changed), so I re-verified it directly against the live server before trusting it:\n\n- `amount: 10.0` (float) \u2192 `/totals` refund stays `0.0`\n- `amount: \"10.0\"` (string) \u2192 `/totals` refund is `10.0`\n\nThe implementation mirrors `submit_batch` but posts to `/refund` and encodes each amount with `str(r[\"amount\"])`, so the test's `12.50 + 7.50` reconciles to `20.00`.
