The note was marked **stale**, so I didn't trust it blindly.\n- I probed the live `/refund` endpoint: numeric `1.00` \u2192 `refund` total `0.0`; string `\"1.00\"` \u2192 `1.0`. The quirk holds for `/refund` too.\n- Implemented `submit_refunds` in `billing/refunds.py` to POST `{\"records\": [{\"id\", \"amount\": str(amount)}]}` to `/refund`, mirroring `submit_batch` but stringifying the amount.\n- Recorded a fresh memory anchored to `submit_refunds` documenting the verified `/refund` behavior.\n\nThe test reconciles the two records ($12.50 + $7.50) to a server-side refund total of $20.00."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 770, "cache_read_input_tokens": 33772, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 770}, "output_tokens": 2, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
